Ⅰ. Ngā wāhanga matua o Pūhaumāota Polyaluminium (PAC) kei roto:
Konumohe waikura (Al₂O₃): he 10%~30% te nui o te waikura, e whakatau ana i te pai o te rere o te waikura, ko te nui ake o te waikura, ko te nui ake o te kiato utu.
Te tote (uara B): tata ki te 85% mō te taumata ahumahi, me te 40%~60% mō te taumata wai inu/taumata kai hei whakaiti i te mōrearea o ngā toenga konumohe.
Te whakahaere i te poke: ka tino whakawhāitihia ngā konganuku taumaha (ārsenic, mata, mercury) me ngā matū kore e rewa i te pikinga o te kounga.
II. Ngā paerewa hanganga o ngā momo rerekē o te PAC (tae atu ki ngā raraunga wai me ngā raraunga totoka)
| Taumata/āhua | taumata hangarau | Ngā taumata wai inu | Kai kounga |
| Ngā āhuatanga wai | Te ihirangi Al₂O₃: 6%~10% Mea kore e rewa i te wai: ≤1.5% Āhua: Wai matotoru parauri, kei roto ngā paru me ngā putunga | Te ihirangi Al₂O₃: ≥10.0% 1 Te rohenga konganuku taumaha: te āheniki ≤ 0.0005%, te konukōrei ≤ 0.00001% Āhua: wai mārama kore tae ki te kōwhai mā | Te ihirangi Al₂O₃: ≥10.0% (i muri i te huringa) Te rohenga konganuku taumaha: te āheniki ≤ 0.0001%, tata ki te 0 Āhua: he wai mārama, he kōwhai mārama, kāore he poke e kitea ana |
| Ngā āhuatanga totoka | Te ihirangi Al₂O₃: 20%~26% Mea kore e rewa i te wai: ≤1.5% Tukanga: Whakamaroke i te pahu, ngā matūriki parauri | Te ihirangi Al₂O₃: ≥29.0% Teihana konganuku taumaha: te āheniki ≤ 0.0005%, te mata ≤ 0.001% Tukanga: Whakamaroke rehu, paura mā/kōwhai mā | Te ihirangi Al₂O₃: ≥29.5% Teihana konganuku taumaha: te āheniki ≤ 0.0001%, te ia o te konganuku taumaha Tukanga: tātari pereti me te anga maha-wāhanga, paura ma parakore |
Ngā rerekētanga matua:
Taumata ahumahi: ko te iti rawa o te ihirangi Al₂O₃ wai (6%~10%) me te nui ake o ngā poke totoka, he iti te utu engari he nui te nui o te paru mā te 20%.
Te taumata wai inu: me eke te matotoru o te wai ki te 1.12g/cm³, neke atu rānei, ā, me puta te totoka i te ine irahiko hei kimi i ngā konganuku taumaha.
Te kounga kai: ko te tere whakarewa totoka e rua te tere o te whakarewatanga o te kounga ahumahi, ā, he nui te utu mō te kawe wai.
III. Te awe o te āhua ki te mahi me te ōhanga
| āhuatanga | PAC wai | PAC tinana totoka |
| taumata hangarau | He tino whai hua, ā, he iti te utu, arā, 30% mō ia tana Ka taea e ngā poke me ngā matūriki te ārai ngāwari i ngā paipa | Ko te roa o te oranga he 12 marama, he pai mō te rokiroki Kua piki ake te rahinga o te paru mā te 20%, kua whakawhāitihia te whānuitanga o te kawe waka |
| Ngā taumata wai inu | Ka taea te whakarewa me te whakamahi tonu, he mea e tika ana mō te tāpiri aunoa ki roto Te tipu wai E toru marama anake te whai mana | E 40 ōrau te iti iho o ngā tukunga waro i ngā wai i ngā tukunga waro mō ngā waka Me whakaoho, me whakarewa hoki, engari ka tutuki i a ia ngā whakaritenga mō te tāruarua o te parahanga ohorere. |
| Kai kounga | Kāore he mōrearea toenga, he pai mō te horoi i ngā taputapu He nui ngā utu mō te kawe waka | Ka whakamahia i roto i ngā whakaritenga ā-waha mā te whakamātautau tātari konumohe e te FDA Ko te utu whakaputa e 2-3 ngā wā he nui ake i te utu ahumahi |
