ʻO ka ʻokoʻa ma waena o ka mea hoʻopaʻa calcium zinc a me ka mea hoʻopaʻa paʻakai kēpau

1. ʻAno hana
ʻO ka mea hoʻopaʻa calcium zinc: kāohi i ka palaho PVC ma o ka hopena synergistic o ke kopa calcium a me ke kopa zinc, ʻoiai e omo ana i ke kinoea HCl i hana ʻia e ka palaho PVC. Loaʻa kona kūpaʻa mai ka hopena hui pū ʻia o nā ʻāpana he nui (e like me nā honua laha ʻole, hydrotalcite, a pēlā aku), hiki ke kāohi i ka palaho catalytic o PVC e nā ion zinc.
ʻO ka mea hoʻopaʻa paʻakai alakaʻi: ke hilinaʻi nei i ka waikawa Lewis ikaika o ka paʻakai alakaʻi e hoʻopau iā HCl, a ke ālai nei i ka hopena decomposition kaulahao PVC ma ka hoʻoneʻe ʻana i nā ʻātoma chlorine paʻa ʻole.
2. Ke kūpaʻa a me ke aloha i ke kaiapuni
Paʻa:
ʻOi aku ka maikaʻi o ke kūpaʻa wela o nā mea hoʻopaʻa paʻakai kēpau, me ke kala mua maikaʻi loa, ka lubricity, a me ke kūpaʻa ʻana i ka wā lōʻihi.
He nāwaliwali ke kūpaʻa mua o nā mea hoʻopaʻa calcium zinc, akā ʻo nā huahana hui pū ʻia e like me ka calcium zinc honua laha ʻole e hoʻomaikaʻi nui i ka hana ma o nā hopena synergistic, e hoʻokokoke ana i ka pae o nā paʻakai kēpau.
Ka launa pū ʻana me ke kaiapuni:
Loaʻa i loko o nā paʻakai kēpau ke kēpau metala kaumaha, kahi e hoʻopilikia ai i ka haumia o ke kaiapuni a me nā pilikia olakino kanaka, a ʻaʻole ia e kūlike me nā lula kaiapuni e like me EU RoHS.
ʻAʻohe metala kaumaha i loko o nā mea hoʻopaʻa calcium zinc, hoʻokō i nā koi o ke kaiapuni, a kū i ka haumia sulfur (e like me ka ʻole e lilo i ʻeleʻele i nā wahi ua waikawa ʻākau).
3. Nā kahua noi
Mea hoʻopaʻa paʻakai kēpau: Ma muli o kona kumukūʻai haʻahaʻa a me ka insulation uila maikaʻi, ua hoʻohana nui ʻia i nā kahua ʻoihana e like me nā kaula a me nā paipu, akā ua hoʻopau mālie ʻia.
Mea hoʻopaʻa calcium zinc: kūpono no nā kahua koʻikoʻi o ke kaiapuni e like me ka ʻōpala meaʻai, nā mea lapaʻau, nā ʻaoʻao o ka puka a me ka puka makani, a ʻaʻohe pilikia o ka haumia keʻa i ka wā e hoʻololi ai me nā paʻakai kēpau a me nā mea hoʻopaʻa organotin.
4. Nā ʻokoʻa ʻē aʻe
ʻO ka nui a me ke kumukūʻai: He haʻahaʻa ka nui o nā mea hoʻopaʻa calcium zinc (ma kahi o 40% haʻahaʻa ma mua o nā paʻakai kēpau), hiki ke hoʻonui i ka nui o ka calcium carbonate i hoʻohana ʻia e hōʻemi i nā kumukūʻai.
Lubrication: ʻOi aku ka maikaʻi o ka lubrication o nā paʻakai kēpau, ʻoiai ʻo ka calcium a me ka zinc e hilinaʻi nei i nā lubricants kōkua e hoʻoponopono i ke kaʻina hana plasticization.
Ka hiki ke puhi ʻana i ka zinc: Pono nā mea hoʻopaʻa calcium zinc i ka hoʻohui ʻana o nā mea kōkua e like me polyols a me phosphites e kāohi i ka hōʻino catalytic o ka zinc chloride.
hōʻuluʻulu manaʻo
ʻOiai he hana maikaʻi loa nā mea hoʻopaʻa paʻakai kēpau, ʻaʻole maikaʻi ko lākou aloha i ke kaiapuni. Ua hoʻemi mālie nā mea hoʻopaʻa calcium zinc i ka hakahaka hana ma o nā hoʻomaikaʻi ʻenehana (e like me nā composites honua laha ʻole) a lilo i mau koho kaiapuni maʻamau.
