ʻO ka hoʻokumu ʻana i ka plastik PVC,
PVC Resin, PVC resin a me ka mea hoʻohui, PVC resin no ka hana ana i ka paipu, PVC SG-5, PVC SG-8, PVS SG-7,

ʻO ka hoʻokumu ʻana i ka plastik PVC ka mea nuiPVC resin a me ka mea hoʻohuis, nā mea hoʻohui e like me ka hana i māhele ʻia i: stabilizer wela, lubricant, hoʻololi hoʻololi, hoʻololi i ka hopena, hoʻopiha, ʻelemakule, colorant a pēlā aku.Ma mua o ka hoʻolālā ʻana i ka hana PVC, pono mākou e hoʻomaopopo mua i nā waiwai o ka resin PVC a me nā mea hoʻohui like ʻole.

Nā mea maka a me nā mea hoʻohui

PVC resin

ʻO ka hana ʻana o ka PVC plastic profile o resin he polyvinyl chloride resin (PVC), ua hana ʻia ʻo PVC me ka vinyl chloride monomer polymerization polymer, hoʻopuka ʻia ka lua wale nō i ka PE, ka helu ʻana i ka lua.

Hiki ke hoʻokaʻawale ʻia ka resin PVC i ke ʻano wehe (XS) a me ke ʻano paʻa (ⅺ) ma muli o nā dispersants ʻokoʻa i ka polymerization.ʻO 0.1-0.2mm ka nui o ka ʻeleʻele, ʻaʻole maʻamau ka ʻili, porous, pulu pulupulu, maʻalahi ke komo i ka plasticizer, ʻoi aku ka nui o ka ʻāpana paʻa ma lalo o 0.1mm, nā lula o ka ʻili, paʻa, ʻano tennis papa, ʻaʻole maʻalahi e hoʻomoʻa i ka plasticizer, ka hoʻohana o kēia manawa. o loose type oi.

Hiki ke hoʻokaʻawale ʻia ka PVC i ka papa maʻamau (PVC toxic) a me ka papa olakino '(non-toxic PVC).Hiki ke hoʻohana ʻia i nā meaʻai a me nā lāʻau lapaʻau e pono ai ka papa olakino o ka vinyl chloride (VC) ma lalo o LOXL0-6.He ʻokoʻa ke kaʻina hana synthetic, hiki ke hoʻokaʻawale ʻia ka PVC i ka PVC suspension a me ka emulsion PVC.E like me ke kūlana aupuni GB / T5761-93 "ka hoʻokuʻu ʻana i ke ʻano o ka polyvinyl chloride resin inspection standard", ʻo ke ʻano o ka hoʻokuʻu ʻana ua māhele ʻia ʻo PVC i PVC-SGL a i PVC-SG8JK resin, ʻoi aku ka liʻiliʻi o ka helu, ʻoi aku ka nui o ka polymerization, ʻoi aku ka nui. ʻO ke kaumaha o ka molekala, ʻoi aku ka kiʻekiʻe o ka ikaika, akā ʻoi aku ka paʻakikī o ke kahe hehee ʻana, ʻoi aku ka paʻakikī o ka hana ʻana.ʻO ke koho kikoʻī, hana i nā huahana palupalu, ka hoʻohana maʻamau o PVC-SGL, PVC-SG2, PVC-SG3 ʻano, pono e hoʻohui i ka nui o nā plasticizers.No ka laʻana, PVC kiʻiʻoniʻoni e hoʻohana ana i ka resin SG-2, e hoʻohui ana i 50 a 80 mau ʻāpana o ka plasticizer.A i ka hana ʻana i nā huahana paʻakikī, mai hoʻohui a hoʻohui i ka plasticizer ma kahi liʻiliʻi loa, e hoʻohana i ka PVC-SG4, VC-SG5, PVC-SG6, PVC-SG7, PVC-SG8 pēlā.E like me ka paipu paʻa PVC e hoʻohana ana i ka resin SG-4, nā kiʻi puka a me nā puka makani e hoʻohana ana i ka resin SG-5, ka pepa alohilohi paʻa e hoʻohana ana i ka resin SG-6, nā kiʻi paʻa paʻa e hoʻohana ana i ka resin SG-7, SG-8.A hoʻohana nui ʻia ka emulsion PVC paste no ka ʻili kūlohelohe, ka pepa pepa a me ka ʻili papahele a me nā huahana plastik.ʻO kekahi mau mea hana resin PVC o ka resin PVC e like me ka polymerization degree (polymerization degree ka helu o nā kaulahao wae, polymerization degree i hoʻonui ʻia e ka molecular kaumaha o ke kaulahao e like me ka molecular weight o ka polymer), e like me Shandong Qilu petrochemical general plant. ka hana ʻana o ka resin PVC, nā huahana hale hana no SK-700;SK – 800;SK – 1000;SK – 1100;SK - 1200, etc. ʻO ka degere kūpono o ka polymerization o ka resin SG-5 he 1000 - 1100. ʻO nā mea kino a me nā kinona o ka resin PVC e ʻike i ka hā.

ʻO ka pauka PVC he pauka keʻokeʻo me ka mānoanoa o 1.35 - 1.45 g/cm3 a me ka mānoanoa o 0.4-0.5 g/cm3.E nānā i ka nui o ka plasticizer maʻiʻo hiki ke maʻalahi, nā huahana paʻakikī, ʻo ka mea plasticizer maʻamau 0-5 nā huahana paʻakikī, 5-25 nā huahana semi-paʻakikī, ʻoi aku ma mua o 25 nā huahana palupalu.

ʻO PVC kahi ʻano amorphous, polar polymer, palupalu ka mahana a me ka hoʻoheheʻe ʻana he kiʻekiʻe, pono ka PVC maʻemaʻe ma 160-210 ~ C plasticizing processing, ma muli o ka paʻa polar ma waena o nā macromolecules no laila e hōʻike ka PVC i kahi hana paʻakikī a brittle.Eia kekahi, nā molekala PVC i loaʻa nā pūʻulu chlorine, ke piʻi ka mahana i 120 ~ C, e hoʻomaka ka PVC maʻemaʻe e wehe i ka hopena HCl, e alakaʻi i ka degradation thermal o PVC.No laila, pono e hoʻohui ʻia nā ʻano mea hoʻohui āpau i ka hana ʻana i ka hoʻololi ʻana o ka PVC a me ka hoʻololi ʻana i ka hopena, i hiki ke hana ʻia i huahana pono.

Hoʻohana nui ʻia ka resin PVC no ka hana ʻana i nā ʻano kiʻi ʻoniʻoni lahilahi (e like me ke kiʻi paʻi i kēlā me kēia lā, kiʻi ʻoniʻoni ʻenehana, kiʻi ʻōmaʻomaʻo mahiʻai, kiʻi wela wela, a me nā mea ʻē aʻe). ʻO nā huahana blister), nā ʻano paipu āpau, e like me ka mea ʻawaʻawa ʻole ma ka paipu threading pipe, ka hose aniani, a me nā mea ʻē aʻe), nā ʻano mea kūikawā like ʻole, e like me ka puka, ka puka makani, ka pā hoʻonani, ka ʻōmole puʻu (no nā mea hoʻonaninani a nā mea inu), Uea, nā ʻano huahana injection a me ka ʻili kūlohelohe, ka ʻili papahele, nā mea pāʻani plastik, etc.

ʻO Zibo Junhai Chemical ka mea mua o Sinopec Qilu, ka inoa PVC nui e like me kēia.
