O le resini mo le gaosia o pepa palasitika PVC o le polyvinyl chloride resin (PVC).Polyvinyl chloride o se polymer e faia i le vinyl chloride monomer.

O le PVC resin e mafai ona faʻavasegaina i ni ituaiga se lua, o se ituaiga taʻavale (XS) ma se ituaiga faʻapipiʻi (XJ), faʻalagolago i le faʻasalalau faʻasalalau i le polymerization.Ole lapo'a fa'amama e 0.1-0.2mm, o le pito i luga e le masani ai, porous, cotton-pei, faigofie ona fa'afefe plasticizer, lapopo'a lapopo'a e itiiti ifo nai lo le 0.1mm, luga e masani, malo, tenisi laulau, faigata ona fa'amalieina plasticizer, I. i le taimi nei, o loʻo faʻaaogaina le tele o ituaiga taʻavale.

PVC e mafai ona vaevaeina i vasega masani (PVC oona) ma tulaga tumama (le-o'ona PVC).O le tulaga tumama e mana'omia ai le vinyl chloride (VC) e itiiti ifo i le 10 × 10-6, lea e mafai ona fa'aoga i mea'ai ma vaila'au.Fa'agasologa synthetic eseese, PVC e mafai ona vaevaeina i le fa'amalologa PVC ma emulsion PVC.E tusa ai ma le tulaga faaleatunuu GB / T5761-93 "Tulaga faʻataʻitaʻiga mo le faʻamoemoe lautele polyvinyl chloride resin mo le faʻamalologa auala", o le faʻamalologa auala PVC ua vaevaeina i PVC-SG1 i PVC-SG8 valu ituaiga resins, lea e laʻititi le numera, o le maualuga o le tikeri o le polymerization, o le mamafa o le molecular foi O le tele o le malosi, o le maualuga o le tafe o le liusuavai, ma sili atu ona faigata le gaioiga.

Pe a filifilia se oloa vaivai, PVC-SG1, PVC-SG2, ma PVC-SG3 e masani ona faʻaaogaina, ma e manaʻomia le faʻaopoopoina o se aofaiga tele o plasticizer.Mo se faʻataʻitaʻiga, o se ata polyvinyl chloride e faia i le resin SG-2, ma faʻaopoopoina le 50 i le 80 vaega o le plasticizer.Pe a gaosia oloa faigata, e masani ona le faʻaopoopoina pe faʻaopoopo mea faʻapipiʻi i ni vaega laiti, o lea e faʻaaogaina ai le PVC-SG4, PVC-SG5, PVC-SG6, PVC-SG7, ma le PVC-SG8.

Mo se faʻataʻitaʻiga, o le SG-4 resin e faʻaaogaina mo le PVC paipa malo, SG-5 resin e faʻaaogaina mo palasitika faitotoa ma faʻamalama faʻamatalaga, SG-6 resin e faʻaaogaina mo ata tifaga manino, ma SG-7 ma SG-8 resin e faʻaaogaina mo fa'ailoga fa'afua malo.Ole auala emulsion PVC fa'apipi'i e masani ona fa'aaogaina mo pa'u pa'u, pepa puipui, pa'u fola ma oloa palasitika.O nisi o gaosi PVC resin e lafo PVC resin e tusa ai ma le tikeri o le polymerization (tikeri o le polymerization o le numera o iunite soʻotaga, o le tikeri o le polymerization faʻateleina i le mamafa mole o le filifili e tutusa ma le mamafa mole o le polymer), pei o le PVC resin gaosia e Shandong Qilu Petrochemical Plant, o fale gaosi oloa O le S-700;S-800;S-1000;S-1100;S-1200.

O le SG-5 resin ei ai le tikeri o le polymerization mai le 1,000 i le 1,100.O le paʻu PVC o se paʻepaʻe paʻepaʻe e iai le mamafa i le va o le 1.35 ma le 1.45 g / cm3 ma le foliga vaaia o le 0.4 i le 0.5 g / cm3.Matou te manatu i mea o loʻo i totonu o mea faʻapipiʻi i totonu o oloa PVC o ni mea vaivai ma faigata.E masani lava, o le plasticizer anotusi o 0 ~ 5 vaega mo oloa faigata, 5 ~ 25 vaega mo oloa semi-malosi, ma sili atu i le 25 vaega mo oloa vaivai.

Zibo Junhai Chemical o loʻo tuʻuina atu le Pvc Resin.E mafai ona matou tuʻuina atu le PVC Resin S3, PVC Resin SG5, PVC Resin SG8, ​​PVC Resin S700, PVC Resin S1000, PVC Resin S1300 ext.Ma e mai i luga o le gaosiga o Saina, e pei o Erdos PVC Resin, Sinopec PVC Resin, Beiyuan PVC Resin, Xinfa PVC Resin, Zhong tai PVC Resin, Tianye PVC Resin.ext.

O le Polyvinyl chloride o loʻo i ai uiga mataʻina o le tele o mea mataʻutia (suauu, limestone, coke, masima ma kesi faʻanatura), faʻagasologa o gaosiga matua, tau maualalo, ma le tele o faʻaoga.Ua avea ma resini lona lua tele-faamoemoega lautele i le lalolagi ina ua uma polyethylene resin.29% o le aofaʻi o le faʻaaogaina o le resin synthetic a le lalolagi.Polyvinyl chloride e faigofie ona faʻaogaina ma e mafai ona faʻaogaina e ala i le faʻapipiʻiina, laminating, tui tui, extrusion, calendering, blow molding, ma isi. Polyvinyl chloride e masani ona faʻaaogaina e gaosia ai mea palasitika vaivai e pei o paʻu faʻaofuofu, ata tifaga, ma faʻalava uaea, faʻapea foʻi. e pei o mea palasitika malo e pei o papatusi, faitotoa ma faamalama, paipa ma valve.
