He maha ngā momo tāpiri mō te PVC (polyvinyl chloride), ka taea te wehewehe i ēnei ki ngā kāwai e whai ake nei i runga i ā rātou mahi, me ngā kai me ngā whakamahinga motuhake e tāpirihia ana:
1. Whakapūmau wera
Mahi: Hei ārai i te tukunga o te HCl nā te pirau wera i te wā e tukatukahia ana, e whakamahia ana rānei te PVC.
Ngā momo noa:
Ngā tote mata (pērā i te trisodium lead sulfate): He iti te utu engari he nui te paitini, ka āta whakamutua.
Pūmau konupūmā konutea: he pai mō te taiao, e whakamahia ana mō ngā takai kai me ngā taputapu hauora.
He mārama pai ngā matū tine waro (pērā i te dibutyltin), ā, he pai mō ngā hua hauora.
Pūmau oneone onge: he huarahi hou e pai ana mō te taiao.
2. Ngā Kaiwhakakirikiri
Mahi: Whakanuia ake te ngāwari me te whakaiti i te pāmahana whakawhiti karāhe.
Ngā momo noa:
Ngā Phthalates (pērā i te DOP, DBP): Whānui, he iti noa te paitini (pērā i te DEHP).
Ngā kōwhiringa pai mō te taiao: Ngā esters Citrate (ATBC), te hinu pīni soya kua whakapūkaratia (ESO), ngā mea whakakirihou polyester.
3. Ngā hinu whakahinuhinu
Mahi: Whakaitihia te waku miihini me te whakapai ake i te rere o te wai.
Kāwai:
Ngā hinu whakahinuhinu ā-roto (pērā i te waikawa stearic): ka whakaiti i te waku i waenga i ngā ngota o te PVC.
Ngā hinu whakahinuhinu o waho (pērā i te paraffin): whakaitihia te waku i waenga i te PVC me ngā taputapu.
4. Whakarerekētanga pānga
Mahi: Whakapai ake i te ātete pānga.
Ngā momo noa:
CPE (Polyethylene Whakapūkara): He tino whai hua te utu.
MBS (methyl methacrylate butadiene styrene copolymer): he pai mō ngā hua mārama.
ACR (kirikiri ester): He mahi tino pai rawa atu.
5. Ngā āwhina tukatuka
Mahi: Whakapai ake i te kaha rewa me te rere o te wai.
Ngā momo noa: ACR (pērā i te raupapa Paraloid), EVA (ethylene vinyl acetate copolymer).
6. Ngā ārai mura
Mahi: Ārai i te mura, e whakamahia ana i roto i ngā rauemi hanga, ngā waea me ngā taura.
Momo:
Ngā rauemi kore-waro: te hauwai konumohe, te hauwai konupora (he pai mō te taiao engari he nui ngā tāpiringa).
Ngā pūhui rauropi: Ngā pūhui bromine (pērā i te decabromodiphenyl ether, he iti te whakawhāititanga), ngā pūhui phosphorus (pērā i ngā phosphate esters).
7. Whakaū rama
Mahi: Ārai i te koroheketanga UV, e whakamahia ana mō ngā hua o waho.
Ngā momo noa:
Ngā mea mimiti UV (pērā i te benzotriazoles).
Pūmautanga mārama amine āraia (HALS).
8. Ngā Whakakī
Mahi: Whakaitihia ngā utu me te whakahaere i te mahi.
Tauira: Konupūmā kāponāte (konupūmā māmā/konupūmā taumaha), paura talc, me te wollastonite.
9. Ngā Tae
Momo:
Ngā tae rauropi: he kanapa te tae.
Ngā tae kore-waro: he ātete pai ki te huarere.
He tohunga a Bontecn Group Haina ki te hanga tāpiringa PVC，I tēnei wā, e rima ngā kaimahi matua o te kamupene R&D, neke atu i te 20 ngā kaimahi waenga R&D, me te neke atu i te 20 ngā rōpū mahi tahi. Ināianei kei te whakawhanake tahi te kamupene me ngā umanga rongonui o tāwāhi i tētahi hua hou, ka taea e te hua te whakaoti rapanga o ngā kai kirihou tuku iho me ngā raruraru utu nui, ā, kua tutuki ngā hua nui. Mā te hangarau tukanga matatau me ngā tikanga kimi tino pai, kei te haere tonu mātou ki te tūhura, ki te arotahi ki te rangahau me te whanaketanga, me te mahi tahi me ngā whare rangahau pūtaiao puta noa i te tau ki te whakawhanake tonu i ngā hua hou me ngā tukanga hou.
