1) Hoʻopili a hoʻopau i ka HCL, kāohi i kona hopena autocatalytic. ʻO kēia ʻano mea hoʻopaʻa e komo pū me nā paʻakai kēpau, nā kopa metala waikawa organik, nā hui organotin, nā hui epoxy, nā paʻakai inorganic, a me nā paʻakai metala thiol. Hiki iā lākou ke hana me HCL a kāohi i ka hana o PVC e wehe i ka HCL.
2) ʻO ke pani ʻana i nā ʻātoma chlorine paʻa ʻole i loko o nā molekala PVC e kāohi i ka wehe ʻana o HCL. Inā hoʻonohonoho ka mea hoʻopaʻa tin organik me nā ʻātoma chlorine paʻa ʻole o nā molekala PVC, e pani ʻia ka tin organik me nā ʻātoma chlorine paʻa ʻole i loko o ke kino hoʻonohonoho.
3) ʻO ka hopena hoʻohui me ke ʻano polyene e hoʻopilikia i ka hoʻokumu ʻia ʻana o ka ʻōnaehana hoʻohui nui a hōʻemi i ke kala. Loaʻa i nā paʻakai waikawa unsaturated a i ʻole esters nā pilina pālua, kahi e hana ai i kahi hopena hoʻohui diene me nā molekala PVC ma o ka hoʻohui ʻana i nā pilina pālua, a laila e hoʻopilikia ana i ko lākou ʻano hoʻohui a pale i ka loli kala.
4) Ke hopu nei i nā radical manuahi a me ka pale ʻana i nā hopena oxidation, hiki i kēia mea hoʻopaʻa wela ke loaʻa i hoʻokahi a i ʻole kekahi mau hopena.
ʻO ka mea hoʻopaʻa wela PVC kūpono he mea hana like ʻole a i ʻole he hui pū ʻana o nā mea e hiki ai ke hoʻokō i nā hana penei: ʻo ka mua, e pani i nā mea pani a paʻa ʻole; ʻO ka lua, ʻo ia ke omo a hoʻopau i ka HCL i hoʻokuʻu ʻia i ka wā o ka hana PVC, e hoʻopau ana i ka hopena hoʻohaʻahaʻa catalytic aunoa o HCL; ʻO ke kolu, ʻo ia ke hoʻopau a hoʻopau paha i nā ion metala a me nā mea haumia ʻino ʻē aʻe e pāʻani ana i kahi hana catalytic i ka hoʻohaʻahaʻa ʻana; ʻO ka hā, hiki i nā ʻano hana kemika like ʻole ke ālai i ka ulu mau ʻana o nā pilina unsaturated a kāohi i ke kala ʻana o ka hoʻohaʻahaʻa ʻana; ʻO ka lima, he hopena pale a pale ia i ka mālamalama ultraviolet. ʻO ka maʻamau, hoʻohana ʻia nā mea hoʻopaʻa wela i ka hui pū ʻana ma muli o ko lākou pono kikoʻī, a he kakaikahi kā lākou hoʻohana pilikino. Eia kekahi, ʻo ka hapa nui o nā ʻano like ʻole he ʻano pauka, a ʻo kekahi he mau kemika ʻawaʻawa loa. I mea e maʻalahi ai ka hoʻohana ʻana, pale i ka lāʻau ʻawaʻawa lepo, hoʻemi i nā mea ʻawaʻawa a hoʻololi paha iā lākou me nā mea ʻawaʻawa ʻole, ua hoʻomohala ʻia nā ʻano mea hoʻopaʻa hui like ʻole ma ka home a ma ka honua holoʻokoʻa i nā makahiki i hala iho nei. No ka laʻana, ʻo ka moʻo hoʻopaʻa hui ʻo German Bear brand, a me nā mea hoʻopaʻa hui tin organik a i ʻole nā mea hoʻopaʻa hui tin organik mai nā ʻāina e like me ʻAmelika Hui Pū ʻIa, Kelemānia, Iapana, a me Netherlands, he nui ka mākeke ma Kina. No laila, he mea nui ka hoʻomohala ʻana o ka ʻoihana plastik o Kina e hoʻolaha piha i ka hoʻohana ʻana i nā mea hoʻopaʻa hui hou i kūpono, haʻahaʻa ke kumukūʻai, ʻaʻohe lepo, ʻaʻohe ʻawaʻawa a haʻahaʻa ka ʻawaʻawa.
