He aha te Whakamātautau Pūwāhi Mirumiru mō ngā Tātari Konganuku Porous? He Aratohu Katoa

Ahakoa te kīanga "5 μm" o tētahi tātari whakarewa kua whakatōngia, kāore taua tau anake e whakaatu i te rahi o tōna ara rere tuwhera nui rawa atu ki tētahi kaihangarau. Mō ngā konganuku pūwero me te whatunga pūwero toru-ahu e hono tahi ana, he mea nui tēnei rerekētanga: ka pā te pūwero nui rawa atu ki te pono o te tātari, te ōritetanga, me te tiakitanga o raro ahakoa te āhua tika o te whakatauranga pūwero ingoa.

Ko tētahi take tēneiwhakamātautau ira mirumirue whakamahia whānuitia ana mō te whakahaere kounga o ngā wāhanga whakarewa porous.

Mō ngā konganuku kua whakakāhia, ko tētahi o ngā tohutoro tino whaitake koISO 4003:1977,Ngā rauemi whakarewa kua whakakāhia kia uru ki roto — Te whakatau i te rahi o ngā pūwero whakamātautau mirumiru[1]. E pā ana te paerewa ki ngā tātari, ki ngā peera porous, ki ngā irahiko porous, me ētahi atu wāhanga kua whakatōngia me te porosity e hono tahi ana. He mea nui, e whakaahua ana a ISO i te whakamātautau mirumiru heiwhakamātautau whakahaere kounga, kaua hei tikanga mō te tautuhi i te rahi pūwero tika, te tohatoha rahi pūwero katoa, te taumata tātari rānei. I arotakehia, ā, i whakaūtia te ISO 4003 i te tau 2022, ā, kei te mau tonu. [1]

He mea nui taua rerekētanga ki te mārama tika ki te whakamātautau ira mirumiru.

I roto i ngā kupu mahi, ka whakautua e te whakamātautau pūwāhi mirumiru tētahi pātai hangarau whai hua:

I tehea pēhanga ka taea e te hau te neke tuatahi i te wai mākū mai i te pūwero nui rawa atu o tēnei hanganga pūwero?

Mā te whakautu ka āwhina i ngā kaihanga me ngā kaiwhakamahi ki te aromatawai i te ōritetanga o ngā pore, ki te kite i ngā ara rere nui rerekē, ki te whakatairite i ngā puranga whakaputa, me te manatoko mēnā ka tutuki i tētahi wāhanga whakarewa pore tētahi whakaritenga kounga kua whakaaetia.

He aha te Whakamātautau Pūwāhi Mirumiru?

Ko te whakamātautau ira mirumiru he tikanga rere-mākū e whakamahia ana hei tautuhi i te pūwero tuwhera nui rawa atu i roto i tētahi rauemi pūwero.

He tino māmā te kaupapa matua.

Ka whakakīia te tātari pūwero ki te wai mākū. Nā te taumahatanga o te mata me ngā kaha o te pūwero, ka noho tonu te wai ki roto i ngā pūwero e hono ana.

Kātahi ka pāngia te pēhanga hau—te nuinga o te hau kōpeke ma, te hauota rānei—ki tetahi taha o te tātari mākū.

I te piki haere o te pēhanga, ka nui hei wikitoria i te kaha o te pūwero e pupuri ana i te wai i roto i te pūwero nui rawa atu. Ka haere te hau mā roto i taua pūwero ka puta he mirumiru i te taha kē.

Ko te pēhanga e pā ana ki te tīmatanga o te āhua pupuhi kua tautuhia ka kiia ko:

Pēhanga Pūwāhi Mirumiru

Ahakoa i tuhia te ASTM F316 mō ngā tātari membrane kaua mō ngā tātari konganuku kua whakatōkia, e whakaahua ana i te kaupapa matua o te capillary: ko ​​te pēhanga iti rawa e hiahiatia ana hei pana i te wai mākū mai i te pūwero ka whakawhirinaki ki te diameter o te pūwero, te kukū mata o te wai, me ngā āhuatanga mākū. [2]

He Huarahi Māmā ki te Whakaaroaro Mōna

Whakaarohia ētahi ngongo karorirori iti rawa kua kī tonu i te wai.

He nui ake te pēhanga e hiahiatia ana hei pana i te wai i roto i tētahi ngongo whaiti i tō te ngongo whānui.

E pā ana te mātāpono whānui kotahi ki tētahi rauemi pūwero e hono tahi ana:

He nui ake te pūwero whai hua → he iti ake te pēhanga e hiahiatia ana

He iti ake te pūwero whai hua → he nui ake te pēhanga e hiahiatia ana

Koia te take e whakarato ai te pēhanga pūwāhi mirumiru i ngā mōhiohio e pā ana ki te pūaha nui rawa atu i roto i te tātari pūaha.

Engari he herenga nui tēnei:

Ka tino hira taua rerekētanga ina aromatawaihia ngā konganuku pūngoi kua sintered.

He pēhea te mahi a te whakamātautau pūwāhi mirumiru?

E whā ngā wāhanga matua o tētahi whakamātautau pūwāhi mirumiru.

Hipanga 1: Whakamakukuhia rawatia te Tātari Porous

Ka whakakīia te wāhanga konganuku pūngoi ki te wai mākū e tika ana.

Me tomo te wai ki roto i ngā pūwero tuwhera, e hono ana, kaua e māku noa i te mata o waho.

I runga i te tukanga whakamātautau me ngā rauemi, ka uru pea ki ngā wai e tika ana he waipiro, he wai whakamātautau rānei kua tohua.

He mea nui te wai whakamakuku nā te meate taumahatanga o te matahe awe tika ki te whanaungatanga i waenga i te pēhanga me te diameter o ngā pore kua tatauhia.

Ko te tikanga tēnei:

He raraunga kāore i oti te pēhanga mirumiru, kāore he mōhiohio e pā ana ki te wai whakamātautau me te tikanga.

Ka taea e ngā taiwhanga e rua te whakamātautau i ngā tātari ōrite mā te whakamahi i ngā wai he rerekē ngā kukū mata, ā, ka whiwhi i ngā pēhanga mirumiru rerekē, me te kore e hē tetahi o ngā taiwhanga.

---

Hipanga 2: Tāpirihia te Pēhanga Hau

Ka pāngia te pēhanga hau ki tetahi taha o te tātari porous kua mākū.

Me whakanui te pēhanga i runga i te tikanga whakahaere.

I te tīmatanga, ka ārai te kaha o te kaha o te wai mākū i te rere o te hau mā roto i te whatunga pūwero kua kī i te wai.

I te pikinga ake o te pēhanga rerekētanga, ka tīmata te hau ki te neke i te wai mai i te ara rere māmā rawa.

---

Hipanga 3: Tāutuhia te Pūwāhi Mirumiru

I tētahi pēhanga, ka pakaru te hau mā roto i tētahi pūwero whai hua, ā, ka kitea ngā mirumiru i te taha whakararo.

I runga anō i te tikanga whakamātautau kua tohua, ka whakatauhia e te kaiwhakahaere, e te taputapu rānei te āhua o te pūwāhi mirumiru kua tautuhia.

E whakaahua ana te ASTM F316 i te pēhanga pūwāhi mirumiru e ai ki te pēhanga e puta ai he rerenga mirumiru pumau i roto i tana tikanga whakamātautau kiriuhi. [2]

Mō te QC ahumahi, he mea nui kia whakaae ngā kaiwhakarato me ngā kiritaki ki te tikanga whakamātautau me te pūwāhi mutunga, kaua e whakataurite i ngā tau pehanga me te kore e mōhio me pēhea te whiwhinga mai.

---

Hipanga 4: Tuhia te Pēhanga me te Arotake i te Hua

Ka taea te whakaatu i te hua hei pēhanga, hei tauira:

•Pae KPa psi

Ka taea hoki te huri heite rahi o ngā pore whakamātautau mirumirumā te whakamahi i te whanaungatanga kua tohua i waenga i te pēhanga, ngā āhuatanga mākū-wai, me te āhua o ngā pūwero.

Mō te QC whakaputa, ka taea e ngā kaihanga te whakarite i tēnei hua ki te awhe whakaae kua whakaaetia, ki ngā raraunga tukanga o mua rānei.

 

---

He aha te hononga o te pēhanga mirumiru ki te rahi o ngā pūwero?

Ko te mātāpono ā-tinana kei muri i te whakamātautau ira mirumiru i ahu mai i te pēhanga o te uaua o te ngākau.

Ko tētahi hononga māmā e whakamahia whānuitia ana ko:

D = 4γ cosθ / ΔP kei hea:

•D= te whānui o ngā pore whai hua

•Γ= te kukū o te mata o te wai mākū

•Θ= te koki whakapā i waenga i te wai me te mata o te pūwero

•ΔP= te pēhanga rerekētanga i te pūwāhi mirumiru

E whakaatu mai ana te whanaungatanga i tētahi mea tino whai hua:

Nō reira:

He mea whai hua tēnei mō te whakatairite i ngā tātari rite i hangaia, i whakamatautauria hoki i raro i ngā āhuatanga whakahaeretia.

Heoi, kaua te whārite e whakamatautau i a tātou ki te whakaaro i tētahi tātari whakarewa kua whakakōpikopikotia hei paihere ngongo karori porotaka tino tika.

Ehara i te mea.

Te Tirohanga Hangarau: Ehara te Pūwero Whakarewa i te Pūwero Tino Pai

Koinei te wāhi e nui ake ai te whakamere o te whakamārama i ngā raraunga mirumiru.

Tērā pea he kōhao āhuahanga kei roto i tētahi pereti keri-reera. Kāore he kōhao kei roto i tētahi tātari paura kua whakakāhia.

I te wā e whakatōngia ana, ka honoa ngā matūriki whakarewa, ka waiho he whatunga āputaputa e hono tahi ana. Ka taea e ēnei ara te huri i te wāhanga whakawhiti, te peka, te hono anō me te whai i ngā ara pikopiko i roto i te rauemi.

He hanganga toru-ahu te hua.

Nō reira, ina puta he "diameter pore whai hua" i roto i te tatau i te pūwāhi mirumiru, kaua e whakamāramatia aunoa me te mea kua keria e tetahi he kōhao porowhita tino tika o taua diameter tonu mā roto i te tātari.

He rite tonu te whakatūpato a ASTM F316 mō te whakamātautau kiriuhi: ko tōna rahi pūwero whai hua i tatauhia e ahu mai ana i tētahi tauira pūwero-pūwero kua whakatauria, ā, kāore e whakaatu tika ana i te pupuri matūriki tuturu. [2]

Mō ngā konganuku kua whakakāhia, e whakapono ana mātou he mea nui ake te whakawhitiwhiti mārama i tēnei rerekētanga.

Ko te ira mirumiru he whakaahuatanga o tētahi whatunga pūwero—ehara i te rūri moroiti e ine ana i ngā āputa katoa i roto i te konganuku.

---

He aha te Ine Tuturu a te Whakamātautau Pūwāhi Mirumiru?

He maha ngā kupu e whakaranua ana i roto i ngā whakatakotoranga whakarewa porous:

•Te rahi o ngā pūwero ingoa, te rahi mōrahi o ngā pūwero, te rahi toharite o ngā pūwero, te whakamātautau mirumiru, te whakatauranga tātari, te tohatoha rahi o ngā pūwero e pupuri ana i te matūriki

Kāore e taea te whakawhiti.

1. Te Putanga-Mai-Pōre Nui Rawa

Koinei te āhuatanga e tino pā ana ki te pūwāhi mirumiru tuatahi.

Ko te ara rere tuwhera nui rawa atu me te whai hua e hiahiatia ana te pēhanga iti rawa hei neke i te wai mākū.

Nā tēnei ka tino whai hua te whakamātautau ira mirumiru mō te tautuhi i ngā ara tuwhera nui kāore i te tūmanakohia.

---

2. Rahi o te Pūwero Ingoa

Ko te whakatauranga micron ingoa a te kaihanga he whakatakotoranga, he whakarōpūtanga rānei o te hua.

Kaua e kiia aunoa he rite tonu ki te rahi o ngā pore i ahu mai i te whakamātautau mirumiru.

Kāore te tātari e hokona ana he momo "5 μm" noa e whakaputa i te rahi o ngā pore whakamātautau mirumiru kua tatauhia he 5.00 μm tonu.

He rerekē ngā mea e whakaahuahia ana e ngā tau e rua.

---

3. Te Rahi Toharite o ngā Pore

Kaua te inenga o te ira mirumiru kotahi e whakamāramatia hei te diameter toharite o ngā pūwero katoa i roto i tētahi hanganga whakarewa kua whakakāhia.

E whakatūpato ana a ISO 4003 kia kaua e whakamahia te whakamātautau mirumiru hei tikanga mō te whakatau i te rahi tika o ngā pore me te tohatoha o te rahi o ngā pore. [1]

---

4. Te Tohatoha Rahi o ngā Pūwero

Mena e hiahiatia ana he whakaahuatanga taipitopito ake mō te tohatoha o ngā pūwero mā roto i tētahi tono, ko ngā tikanga pēnei i tete ine i te rere o te capillarytērā pea he nui ake ngā kōrero.

Ka arotakehia e ēnei tikanga te whanonga rere o te hau mākū me te hau maroke puta noa i te awhe pehanga, kaua ki te whakawhirinaki anake ki te āhua pakaru tuatahi.

---

5. Te Pupuri Matūriki

Ko tētahi atu pūtake noa tēnei o te whakapoauau.

Mā te whakamātautau mirumiru i tatauhia te rahi o ngā porekāore e ōrite aunoa ki te rahi o te matūriki iti rawa ka puritia e te tātari.

Ka whakawhirinaki pea te whanonga tātari tuturu ki:

•Āhuatanga o ngā pūwero te hohonu o ngā pūwero te piko o te āhua o te matūriki te tohatoha rahi o te matūriki te hanganga keke ngā āhuatanga wai te tere rere ngā taunekeneke mata pēhanga rerekē

Waihoki, e kī ana a ASTM F316 kaua ngā hua o te mirumiru e whakamahia hei take anake mō te whakaahua i te pupuri i te paru-matūriki. [2]

Te Māramatanga Hangarau

Mena ka mea te kaiwhakarato:

"E mea ana tō mātou pūwāhi mirumiru he 5 μm, nō reira he 5 μm te tapeke o te matūriki e mau ana i tēnei tātari." Me kite anō mātou i ētahi atu taunakitanga i mua i te whakaae ki taua whakatau.

Mō tētahi tono tātari nui, me noho te pūwāhi mirumiru hei wāhanga kotahi o te panga whakamana—kaua ko te panga katoa.

 

---

Te Pūwāhi Mirumiru vs. Te Rahi o ngā Pūwero Ingoa vs. Te Whakatauranga Tātari

He mea nui tēnei rerekētanga hei whakarāpopototanga:

Mō ngā tono uaua, me karo ngā kaihangarau i te whiriwhiri i tētahi tātari mai ikotahi te tau maikorona anake.

---

He aha te hiranga o te whakamātautau ira mirumiru mō ngā tātari konganuku kua whakatōkia?

Ka mārama ake te uara tūturu o te whakamātautau mirumiru ina whakamahia hei taputapu hanga me te taputapu QC.

1. Te Kite i ngā Pūwero Nui Rawa

Whakaarohia kia rua ngā kōpae tātari kua whakakōpikopikotia i hangaia mai i te rauemi kotahi me te taumata ingoa kotahi.

He rite tonu pea te nuinga o ngā hanganga o ō rātou pūwero.

Engari ki te mea he ara rere nui ā-rohe tō roto, ka puta pea tōna pakarutanga hau tuatahi i te pēhanga iti iho.

Ka whai hua pea te whakamātautau ira mirumiru mō te tautuhi i ngā āhuatanga rerekē o te hanganga o ngā kōhao e uaua ana ki te kite ā-kanohi.

---

2. Te Tirotiro i te Ritenga o te Hanganga

Ko te mahi a te konganuku porous sintered e whakawhirinaki ana ki ngā taurangi hanga maha, tae atu ki:

•Ngā āhuatanga o te paura whakarewa, te tohatoha rahi-matūriki, ngā tikanga hanga, te kiato matomato, te pāmahana, te hau, te hau, te wā, te mīhini, te horoi, te whakarewa, te horoi, te hau ...

Me whakaputa e tētahi tukanga whakaputa whakahaeretia ngā āhuatanga pūngao ōrite tonu mai i tētahi rota ki tētahi rota.

Mā te aroturuki i ngā hua o te mirumiru ka āwhina i ngā kaihanga ki te tautuhi i te rerekētanga o te tukanga.

---

3. Manatoko Pono

Ka taea hoki e te whakamātautau ira mirumiru te āwhina ki te whakaatu i ngā ara rere tuwhera rerekē.

I roto i ngā tono membrane, e kī ana a ASTM ko te whakamātautau ira mirumiru ka tohu pea i te kino o te membrane, te koretake o ngā hiri, te turuturu rānei o te pūnaha. [2]

He rerekē ngā momo rahunga mō ngā wāhanga whakarewa-whakakotahi pakari, engari he whai hua tonu te ariā QC matua:me rangahau te putanga wawe ohorere o te hau.

I runga i te waahanga, ko nga take pea ko:

•He hapa o te pore ā-rohe

•Te kino i te wā tukatuka tuarua

•He take i roto i tētahi huihuinga

---

4. Te Whakataurite i ngā Puranga Whakaputa

Mō ngā ota pakihi-b2b auau, he mea nui te ōritetanga, pērā anō i te whakatakotoranga ingoa.

He maha ngā wā ka hiahia te kaihoko e hoko ana i ngā rau, i ngā mano rānei o ngā wāhanga porous:

Kia rite te whanonga o te Rota 12 ki te Rota 11.

Mā ngā raraunga pūwāhi mirumiru, me te uruhanga me te tirotiro i ngā āhuatanga, ka taea te whakarato i tētahi pikitia puranga-ki-puranga he nui ake te whai tikanga i te tuhi noa i te "10 μm" ki ia tuhi.

---

Whakamātautau Pūwāhi Mirumiru vs. Ētahi Atu Whakamātautau Konganuku Pūwero

Kāore he whakamātautau kotahi e tino whakaahua ana i tētahi tātari whakarewa pūngoi.

Mō ngā tono ahumahi, he maha ngā tikanga ka taea te whakamahi tahi.

Mō ngā rauemi konganuku kua whakakāhia kia uru ki te wai,ISO 4022:2018ka hipokina motuhaketia te whakatau i te uruhanga wai. [3]

He mea ako tēnei wehenga:

He hononga tō te āhua o ngā pore me te uruhanga, engari he rerekē te āhua.

He maha ngā wā e hiahiatia ana ngā mea e rua mō tētahi tātari kua hangaia paitia.

---

Te Tirohanga Hangarau: Kaua e Arotauhia te Pūwāhi Mirumiru i te Takitahi

Ko tētahi whakaaro hē ka kitea i ētahi wā i roto i te kōwhiringa tātari ko:

"He pai ake te pūwāhi mirumiru teitei ake."

Kāore i te pono tonu tēnā.

Ko te pūwāhi mirumiru teitei ake e tohu ana i te iti ake o te pūaha uru nui rawa atu i raro i ngā tikanga whakamātautau rite.

Engari ka taea hoki e ngā pūwero iti ake te whakanui ake i te ātete ki te rere.

I roto i tētahi pūnaha tūturu, me whakataurite pea e ngā kaihangarau:

Pupuri ↔ Hekenga Pēhanga ↔ Tere Rere ↔ Āheinga Pupuri-Paru ↔ Kaha Ā-Mīhini

Hei tauira, mā te hanga i tētahi tātari hau kia tino whakanikoniko atu i te mea e tika ana, ka puta he rahi whakamiharo o ngā pūwero, ā, ka nui rawa te hekenga pehanga.

Nō reira, ehara te tātari "pai rawa" i te tātari me te pūwāhi mirumiru teitei rawa.

Koinei te tātari e rite ana te hanganga o ōna pūwero me ōna āhuatanga rere ki ngā whakaritenga o te tukanga.

E hangai ana tēnei ki tētahi kitenga e puta pinepine ana i roto i ngā kōrero hangarau whakarewa porous: ehara te porousity i te hapa hangahanga hei whakakore noa iho; i roto i tētahi tātari porous, ko te whatunga pore whakahaeretia tonu te āhuatanga mahi o te wāhanga. Nō reira, ka kōrerohia e ngā kaihangarau ahumahi te pūwāhi mirumiru me te permeability kaua hei inenga motuhake. [4]

---

He aha ngā āhuatanga ka pā ki ngā hua o te whakamātautau mirumiru?

He māmā noa iho te āhua o te whakamātautau ira mirumiru, engari he maha ngā taurangi ka pā nui ki te hua.

Wai Whakamākū

Ka uru tika te kukū o te mata ki te whanaungatanga pēhanga-pūwero.

Nō reira, mā te whakarerekē i te wai whakamātautau ka taea te whakarerekē i te pehanga i inehia.

Koia te take me tautuhi te pūrongo hangarau i te wai mākū.

---

Te Whakamakuku Katoa

Ki te kore e mākū tika te hanganga pūngoi, ka taea e te hau kua mau te whakaputa i ngā hua hē.

Ka tino whai pānga tēnei ki:

•Ngā pūwero tino angiangi Ngā āhua matatini Ngā mata kua poke Ngā ngongo pūwero roa Ngā hanganga matapo, ngā hanganga kua kapi katoa rānei

---

Koki Whakapā

He mea nui anō hoki te taunekeneke i waenga i te wai mākū me te mata whakarewa.

Ka pā pea te āhua o te mata, te poke me te matū ki te whanonga mākū.

---

Te pāmahana

Ka rerekē te kukū o te mata i te pāmahana.

Hei whakatairite i te tika, me whakahaere, me tuhi rānei i ngā āhuatanga whakamātautau.

---

Te Whakamāramatanga o te Ara Pēhanga me te Pūwāhi Mutunga

Mā te tere o te pikinga o te pehanga ka uaua ake te tautuhi i te putanga tuatahi.

Ka pai ake te auautanga mā te tukanga whakahaere.

---

Te Parahanga o te Mata

Ka taea e te hinu, ngā toenga mīhini, ngā matū horoi me ētahi atu poke te whakarerekē i te whanonga mākū.

Nō reira, me horoi tika te tātari i mua i te whakamātautau kia rite ki te tikanga kua tautuhia.

---

Āhuahanga Pore

He koretake, he pīrori hoki ngā pūwero tūturu kua whakapōturitia.

Koinei tētahi o ngā take e tika ana kia whakaarohia te whānui o ngā pore hei mea nuiāhuatanga whai hua, ehara i te whakaahuatanga āhuahanga katoa.

---

He aha i taea ai e ngā taiwhanga e rua te whakaputa hua rerekē mō ngā ira mirumiru?

Me kī, ka pūrongo mai te Taiwhanga A:

Pūwāhi Mirumiru: 0.8 pae i te mea e whakaatu ana te Taiwhanga B:

Pūwāhi Mirumiru: 1.0 pae

He tikanga anō tēnā kei te hē tetahi taiwhanga?

Kāore.

I mua i te whakataurite i ngā tau, tirohia:

1.I whakamahia rānei e rātou te wai whakamakuku kotahi?

2.I rite te pāmahana o te wai?

3.I mākū katoa te tātari?

4.I whakamahia te pito pūwāhi mirumiru kotahi?

5.I rite anō te arawhata pēhanga?

6.I whakamahia te tikanga tatau kotahi?

7.I horoia te tātari i taua ara anō?

8.I hiritia tika te taputapu whakamātautau?

Te Māramatanga Hangarau

Mō te tohu a te kaiwhakarato, ka tūtohu mātou kia kaua e whakamahia ngā whakatakotoranga e kī ana:

"Pūwāhi Mirumiru ≥ Pae X."

E tautuhia ana tete tikanga whakamātautau me te wai whakamātautau me te paearu whakaae.

Ki te kore, ka whakataurite pea ngā kaiwhakarato me ngā kiritaki i ngā tau i puta i raro i ngā āhuatanga ā-tinana rerekē.

ISO 4003: Te Paerewa Whakamātautau Mirumiru Matua mō te Mea Whakarewahia

Mō ngā wāhanga whakarewa kua whakatōkia ki roto i te pūwero,ISO 4003:1977he mea tino nui.

Ko tōna taitara ko:

Ngā rauemi whakarewa kua whakakāhia kia uru ki roto — Te whakatau i te rahi o ngā pūwero whakamātautau mirumiru

Ka kapi te whānuitanga i ngā tātari, ngā whāriki porous, ngā irahiko porous me ētahi atu wāhanga he porous honohono. Kei te whakaputaina tonutia te paerewa, ā, kei te whai mana tonu i muri i tōna whakaūnga i te tau 2022. [1]

Ehara pea i te mea ko te huarahi anake ki te whakahaere i te whakamātautau te karere tino whai tikanga i roto i te ISO 4003.

Koinei te āhuakaua e whakamārama.

Ka whakatūria e ISO te whakamātautau mirumiru heiwhakamātautau whakahaere kounga, kaua hei tikanga mō te whakatau i te rahi tika o te pūwero, te tohatoha rahi katoa o te pūwero, te taumata tātari rānei. [1]

Me whai pānga taua kōrero ki te āhua o te tuhi a ngā kaihangarau i ngā whakatakotoranga tātari.

---

Ā, me pēhea rā te ASTM F316?

He maha ngā wā ka tūtakihia te ASTM F316 i roto i ngā rangahau whakamātautau ira mirumiru.

Ko tōna taitara katoa ko:

Ngā Tikanga Whakamātautau Paerewa mō ngā Āhuatanga Rahi o ngā Pūwero o ngā Tātari Kiriuhi mā te Ira Mirumiru me te Whakamātautau Pūwero Rere Toharite.

E ai ki a ASTM ka taea te whakamahi i te tikanga hei whakatau me te whakatairite i te rahi o ngā pore mōrahi, ā, ka whakamāramahia te whanaungatanga i waenga i ngā kaha o te wai mākū me te pēhanga o te ira mirumiru. [2]

Heoi anō, he rerekētanga nui tēnei:

He paerewa tātari kiriuhi te ASTM F316. E aro tika ana te ISO 4003 ki ngā rauemi konganuku kua whakakāhia kia uru ki roto.

Nō reira, ina kōrerohia te maitai kore waikura kua whakakōpikopikotia, te nikara, te taitīnati me ētahi atu wāhanga konganuku pūngoi, ko te ISO 4003 te tohutoro e tika ana.

He whai hua tonu te ASTM F316 mō te mārama ki te mātāpono o te ira mirumiru me ngā herenga o te whakamaoritanga i tētahi tataunga pore whai hua ki te pupuri matūriki tuturu.

Tō Mātou Tirohanga Hangarau: Whakaarohia he Matapihi "Pore-Rere-Kaha"

Mō ngā kaupapa whakarewa porous maha, he pai ake te whakaaro ki te kōwhiringa tātari heimatapihi mahikaua ki tētahi whakatakotoranga kotahi.

E toru ngā taurangi e tino hira ana:

Hanganga Pūwero → Mahi Rere → Pūmautanga Mīhini

Mā te whakarerekē i tētahi ka pā ki tētahi atu.

Hei tauira:

•Tērā pea ka pai ake te pupuri i te wai e ngā pūwero angiangi engari ka nui ake te hekenga o te pēhanga;

•Tērā pea ka pai ake te uruhanga o te wai i te nui o te porosity, engari ka pā ki ngā āhuatanga hangarau;

•Tērā pea ka whakapai ake ngā rauemi matotoru i te pakari o te hanganga engari ka whakarerekē i te ātete rere;

•Ka pā te rerekētanga o ngā āhuatanga o te paura ki te tohatoha o ngā pore me te uruhanga.

Koia te take e whai hua ake ai ngā raraunga ira mirumiru ina honoa ki ētahi atu inenga.
