YIHOO PVC (polyvinyl chloride) polymerization & hoʻololi i nā mea hoʻohui

Hōʻike Pōkole:

ʻO Polyvinyl chloride (PVC) kahi polymer o vinyl chloride monomer (VCM) i polymerized e ka peroxide, azo compound a me nā mea hoʻomaka ʻē aʻe a i ʻole nā ​​radical polymerization react i hana ma lalo o ka hana o ka mālamalama a me ka wela. Ua kapa ʻia ka vinyl chloride homo polymer a me ka vinyl chloride co polymer.

ʻO ka PVC ka mea nui loa i hana ʻia i loko o ka honua a hoʻohana nui ʻia. Hoʻohana ākea ia i nā mea kūkulu hale, nā huahana ʻoihana, nā pono o kēlā me kēia lā, ka ʻili papahele, nā pōhaku lepo, nā ʻili hana, nā paipu, nā kaula a me nā kaula, nā kiʻi ʻūlū, nā ʻōmole, nā mea huʻi, nā mea hoʻopaʻa, nā olonā a pēlā aku.

ʻO Polyvinyl chloride (PVC) kahi polymer o vinyl chloride monomer (VCM) i polymerized e ka peroxide, azo compound a me nā mea hoʻomaka ʻē aʻe a i ʻole nā ​​radical polymerization react i hana ma lalo o ka hana o ka mālamalama a me ka wela. Ua kapa ʻia ka vinyl chloride homo polymer a me ka vinyl chloride co polymer.

ʻO ka PVC ka mea nui loa i hana ʻia i loko o ka honua a hoʻohana nui ʻia. Hoʻohana ākea ia i nā mea kūkulu hale, nā huahana ʻoihana, nā pono o kēlā me kēia lā, ka ʻili papahele, nā pōhaku lepo, nā ʻili hana, nā paipu, nā kaula a me nā kaula, nā kiʻi ʻūlū, nā ʻōmole, nā mea huʻi, nā mea hoʻopaʻa, nā olonā a pēlā aku.

ʻO ka PVC kahi ʻano amorphous o ka pauka keʻokeʻo, me ke kēkelē branched haʻahaʻa. ʻO 77 ~ 90 temperature kona ana wela hoʻololi, a hoʻomaka e hoʻopau i ka170 ℃. I kēia manawa ʻaʻohe kūpaʻa maikaʻi o ka mālamalama a me ka wela: e hoʻopau a hana ia i ka hydrogen chloride ma luna o 100 ℃ a i ʻole ma hope o ka lōʻihi o ke kū ʻana o ka lā, a me ka hoʻohui pū ʻana me ka catalytic, ka mea e hoʻoliʻiliʻi a hāʻule i ke kino a me ka mechanical., , stabilizer a i ʻole nā ​​mea hoʻohui e pono e hoʻohui i mea e hoʻomaikaʻi ai i ka paʻa o PVC.

Hiki i ka ʻoihana ke hāʻawi i lalo o nā hua hoʻohui foaming PVC:

KUPANAHA HUAOLELO CAS ʻAno KANAKA NĀ PALAPALA
ANTIOXIDANT YIHOO AN245DW 36443-68-2 35% 7732-18-5 65% SONOX 2450DW Hoʻohana nui ʻia i ka styrene, kāpili synthetic, POM homopolymer a me copolymer, PU, ​​PA, PET, MBS, a me PVC.
YIHOO AN333 77745-66-5 JP333E Phenol-free antioxidant, i hoʻohana ʻia ma ke ʻano he stabilizer kōkua kōkua ma PVC, hoʻomaikaʻi i ke kala a me ka transparency o nā huahana PVC. Hiki nō ke hoʻohana i loko o ka laholio a me ka PU mea e hoʻomaikaʻi i ke kūnewa kūpaʻa o nā huahana.
YIHOO HP136 181314-48-7 Hiki iā ia ke hāʻawi i ka hydrogen hana e hoʻohou hou i ka phenolic antioxidant ālai ʻia a hoʻemi i ka lakio i hoʻohui ʻia o nā AO ʻelua. Kūpono no nā noi hana pāmahana kiʻekiʻe, PP, ʻili membrane BOPP, mea pono PC hoʻopōʻaiapuni, styrene polymer, PPR paipu mea, TPU, lina, etc.

No ka hoʻolako ʻana i nā mea hoʻopili polymer i nā noi kikoʻī hou aʻe, ua hoʻokumu ka ʻoihana i kahi moʻo huahana e uhi ana ma lalo o nā noi: PA polymerization & moditive additives, PU hua hua hoʻohui, PVC polymerization & hoʻololi hoʻololi, PC mea hoʻohui, TPU elastomer mea hoʻohui, haʻahaʻa VOC kaʻa ʻoki nā mea hoʻohui lole hoʻopau. nā mea hoʻohui āpau, nā mea hoʻohui uhi, nā mea hoʻonaninani mea hoʻopili, API a me nā huahana kemika e like me zeolite a pēlā aku.

Hoʻokipa ʻia ʻoe e kāhea iā mākou no nā nīnau!
