Ko te kaiwhakahaere pahuka PVC he tāpiringa pūmua e whakamahia ana hei whakapai ake i te mahi a ngā hua pahuka PVC. Ko āna mahi matua he whakanui i te kaha rewa, te whakatairanga i te ōritetanga o ngā pūtau pahuka, te ārai i te hinga o ngā pūtau, me te arotau i te mahi tukatuka. Koinei te whakataki whānui ki ngā kaiwhakahaere pahuka PVC:
1. Te mahi a te kaiwhakahaere pahuka PVC
Whakapai ake i te kaha rewa: ārai i ngā mirumiru kei pahū, kei hanumi rānei i te wā e pupuhi ana, ā, kia ōrite ake te hanganga o te pūtau.
Hanganga pūtau pumau: ka whakaiti i te hinganga o te pūtau, ka whakapai ake i te kaha ā-pūkaha me te kounga o te mata o te hua.
Whakapai ake i te mahi tukatuka: Arotauhia ngā āhuatanga rheological o te PVC rewa kia pai ake ai mō ngā tukanga pahuka extrusion, rolling, injection molding rānei.
Te whakarerekē i te mātotoru o te pahuka: te whakahaere i te rahi me te tohatoha o ngā pūwero pahuka hei whakatutuki i te pānga māmā e hiahiatia ana o te hua.
2. Te whakarōpūtanga o ngā whakarerekētanga pahuka PVC
(1) Whakarōpūtia e te hanganga matū
Ngā ester kiriaku (momo ACR): ko ngā mea tino noa, pērā i ngā copolymer methyl methacrylate (MMA) – butyl acrylate (BA), he tino pai ngā pānga whakapakari rewa.
Styrene acrylonitrile (momo SAN): He pai tōna ātete wera, ā, he pai mō ngā tukanga pahuka pāmahana teitei.
MBS (methyl methacrylate butadiene styrene): He mahi whakapakeke, he mahi whakahaere pahuka hoki āna.
(2) Whakarōpūtia mā te āhua ā-tinana
Momo hinu: whakamahia tika mō te pahuka kapia whakapiri PVC (pēnei i te hiako horihori, te pepapātū).
Momo paura: whakamahia mō te whakapūpū i te PVC mārō (pērā i ngā papa pahuka whakakikoruatia, ngā kōtaha).
3. Ngā mara tono o te kaiwhakahaere pahuka PVC
| rohe tono | ngā hua noa | Ngā whakaritenga a te kaiwhakahaere |
| Whakapaipai whare | Papa pahuka PVC, papa whakarara, kōtaha rakau rūpahu | He kaha rewa teitei, he rahi ōrite o ngā pore, ā, he ātete pai ki te huarere |
| Roto o te Motuka | Papa taputapu, papa tatau, tuanui | He iti te kakara, he ātete ki te pāmahana teitei, ā, he ātete ki te koroheketanga |
| ngā rauemi tākai | Tākai pūwero, paepae kai | Kāore he paitini, ā, e tutuki ana i ngā paerewa FDA |
| Ngā rauemi hu me te hiako hangai | Taka pahuka EVA/PVC, hiako hangai | He ngawari pai, he manawanui teitei |
4. Ngā āhuatanga whiriwhiri o te kaiwhakahaere pahuka PVC
