Aia nā ʻano mea hoʻohui like ʻole no ka PVC (polyvinyl chloride), hiki ke puʻunaue ʻia i nā ʻāpana ma lalo nei e pili ana i kā lākou mau hana, me nā mea hoʻohui kikoʻī maʻamau a me nā hoʻohana i hoʻopili ʻia:
1. Mea hoʻopaʻa wela
Hana: No ka pale ʻana i ka hoʻokuʻu ʻia ʻana o HCl ma muli o ka palaho wela i ka wā o ka hana ʻana a i ʻole ka hoʻohana ʻana i ka PVC.
Nā ʻano maʻamau:
Nā paʻakai kēpau (e like me ka trisodium lead sulfate): Haʻahaʻa ke kumukūʻai akā kiʻekiʻe ka ʻawahia, hoʻopau mālie ʻia.
Mea hoʻopaʻa calcium zinc: pili i ke kaiapuni, hoʻohana ʻia no ka hoʻopili ʻana i ka meaʻai a me nā mea lapaʻau.
He ʻano moakaka maikaʻi nā hui tin organik (e like me dibutyltin) a kūpono no nā huahana lapaʻau.
Mea hoʻopaʻa honua laha ʻole: he koho ʻē aʻe hou e pili ana i ke kaiapuni.
2. Nā mea hoʻopili palakiko
Hana: Hoʻonui i ka maʻalahi a hoʻohaʻahaʻa i ka mahana hoʻololi aniani.
Nā ʻano maʻamau:
ʻO nā Phthalates (e like me DOP, DBP): Universal, kaupalena hapa ʻia ka ʻawahia (e like me DEHP).
Nā koho ʻē aʻe e pili ana i ke kaiapuni: Citrate esters (ATBC), ʻaila soya epoxidized (ESO), polyester plasticizers.
3. Nā mea hoʻoluʻu
Hana: E hōʻemi i ka friction machining a hoʻomaikaʻi i ke kahe ʻana.
Māhele:
Nā mea hoʻoluʻu kūloko (e like me ka waikawa stearic): e hōʻemi i ka friction intermolecular o PVC.
Nā mea hoʻoluʻu waho (e like me ka paraffin): e hoʻēmi i ka friction ma waena o ka PVC a me nā lako.
4. Mea hoʻololi hopena
Hana: Hoʻomaikaʻi i ke kūpaʻa hopena.
Nā ʻano maʻamau:
CPE (Chlorinated Polyethylene): Kūʻai kūpono kiʻekiʻe.
MBS (methyl methacrylate butadiene styrene copolymer): kūpono no nā huahana moakaka.
ACR (acrylic ester): Hana piha maikaʻi loa.
5. Nā mea kōkua hana
Hana: Hoʻomaikaʻi i ka ikaika hoʻoheheʻe a me ke kahe ʻana.
Nā ʻano maʻamau: ACR (e like me ka moʻo Paraloid), EVA (ethylene vinyl acetate copolymer).
6. Nā mea pale ahi
Hana: Kāohi i ke kuni ʻana, hoʻohana ʻia i nā mea kūkulu hale, nā uea a me nā kaula.
ʻAno:
Nā mea inorganic: alumini hydroxide, magnesium hydroxide (aloha i ke kaiapuni akā me ka nui o nā mea hoʻohui).
Nā hui organik: Nā hui Bromine (e like me ka decabromodiphenyl ether, i kaupalena hapa ʻia), nā hui phosphorus (e like me nā phosphate esters).
7. Mea hoʻopaʻa kukui
Hana: Anti UV aging, hoʻohana ʻia no nā huahana waho.
Nā ʻano maʻamau:
Nā mea hoʻoheheʻe UV (e like me benzotriazoles).
Mea hoʻopaʻa kukui amine i pale ʻia (HALS).
8. Nā mea hoʻopiha
Hana: E hōʻemi i nā kumukūʻai a hoʻoponopono i ka hana.
Nā Laʻana: Calcium carbonate (calcium māmā/calcium kaumaha), pauka talc, a me ka wollastonite.
9. Nā mea hoʻoluʻu
ʻAno:
Nā pigment organik: ʻālohilohi nā kala.
Nā pigments inorganic: kūpaʻa maikaʻi i ka wā.
He loea ʻo Bontecn Group Kina i ka hana ʻana i nā mea hoʻohui PVC, I kēia manawa, he 5 mau limahana R & D koʻikoʻi o ka hui, ʻoi aku ma mua o 20 mau limahana R & D waena, a ʻoi aku ma mua o 20 mau hui hana like. I kēia manawa, ua hui pū ka hui a me nā ʻoihana kaulana o nā ʻāina ʻē i kahi huahana hou, hiki i ka huahana ke hoʻoponopono i nā pilikia mea hoʻohui plastik kuʻuna a me nā pilikia kumukūʻai kiʻekiʻe, a ua hoʻokō i nā hopena koʻikoʻi. Me ka ʻenehana hana holomua a me nā ʻano ʻike kūpono, hoʻomau mākou i ka ʻimi, kālele i ka noiʻi a me ka hoʻomohala ʻana, a hana pū me nā ʻoihana noiʻi ʻepekema i ka makahiki holoʻokoʻa e hoʻomau i ka hoʻomohala ʻana i nā huahana hou a me nā kaʻina hana hou.
Ka manawa hoʻouna: ʻOkakopa-13-2025
