Ko te mahi a ngā āwhina tukatuka ACR i roto i te tukatuka PVC e whakaatahia ana i roto i te whakatairanga i te kirihou, te whakapai ake i ngā āhuatanga rewa, te whakarei ake i te pumau tukatuka, te arotau i te kounga hua, me te whakarei ake i te urutau tukanga motuhake.
1. Whakatairanga i te whakakirikiri
Ka taunekeneke a ACR me ngā mekameka ngota PVC mā roto i ngā rōpū porowhita, ka whakaiti i te waku i waenga i ngā matūriki, ka tere ake te whakakirikiritanga rewa, ka whakapoto i te wā tukatuka (pēnei i te ACR-201, e whakaiti ana i te wā whakakirikiritanga mā te 40-60 hēkona), ā, ka taea te whakaheke i te pāmahana whakakirikiritanga mā te 10-20 ℃ (mō ngā tauira kei roto ngā rōpū waikawa carboxylic).
2. Whakapai ake i te mahi rewa
Whakarei ake i te kaha rewa: Ka hangaia e ngā mekameka ngota roa he whatunga honohono ā-tinana, ka whakanui ake i te kaha rewa mā te 300% (ACR-401), ka ārai i te pakaru rewa o te putanga (pēnei i te āhuatanga kiri mango);
Whakapai ake i te rere o te wai: whakaitihia te matotoru rewa mā te 10-15% me te whakarei ake i te pai o te whakakī i ngā tere kutikuti teitei.
3. Whakapai ake i te pumau o te tukatuka
Ārai i te wera nui o te rohe, whakapiki ake i te pāmahana tīmatanga o te pirau wera PVC mai i te 190 ℃ ki te 210 ℃, whakaitihia ngā piki me ngā heke o te pāmahana rewa, me te whakaiti i te taipana mā te 15-20% ina whakakotahihia ki ngā hinu whakahinuhinu (ACR-530).
4. Whakapai ake i te kounga o te hua
Te whakakore i ngā hapa o te mata pērā i ngā kanohi ika me ngā tohu rere, ka whakapai ake i te maeneene (pērā i te kohu <3%, te kanapa neke atu i te 90%); Te whakapakari i te pakari o te pānga (5-10 ngā wā ka whakanui ake i te kaha o te pānga ki te pāmahana iti) me te ātete ki te huarere.
5. Tautoko i ngā tukanga motuhake
Mara pahuka: Whakapai ake i te kaha o te rewa kia ōrite, kia mātotoru hoki ngā pore pahuka;
Hua mārama: he taupū whakaata PVC e ōrite ana (kohu ACR-Z30 <3%);
Mara hauora: Whakaitihia te ua (ka whakaitihia e ngā tauira kei roto ngā rōpū waikawa carboxylic te tukunga HCl mā te 60%).
He rerekē ngā tauira e tika ana mō ngā tukanga motuhake: ka whakarei ake te ACR-401 (whakaputa/hurihuri) i te kaha rewa, ka arotau te ACR-201 (werohanga/whakakikorua) i te rere o te wai, ka whakataurite te ACR-530 i te pūnaha whakahinuhinu.
