Matyè premyè pou prepare corrugated doub-miray difisil PVC tiyo
Matyè premyè pou prepare tiyo corrugated doub-miray difisil PVC,
Materyèl bwit pou pwodwi corrugated doub-miray PVC tiyo,
Polyvinyl Chloride (PVC) se yon résine thermoplastique lineyè ki te pwodwi pa polymérisation monomère klori vinil.Akòz diferans nan matyè premyè, gen de metòd pou sentèz klori vinil monomè kalsyòm carbure pwosesis ak pwosesis petwòl.Sinopec PVC adopte de pwosesis sispansyon, respektivman soti nan Japonè Shin-Etsu Chimik Konpayi ak Ameriken Oxy Vinyls Konpayi.Pwodwi a gen bon rezistans korozyon chimik, ekselan pwopriyete izolasyon elektrik ak estabilite chimik amann.Avèk kontni klò segondè, materyèl la gen bon rezistans dife ak pwopriyete pwòp tèt ou-extend.PVC fasil pou trete pa extrusion, bòdi piki, kalandriye, bòdi kònen, konpresyon, bòdi jete ak bòdi tèmik, elatriye.
Aplikasyon
PVC se youn nan résine thermoplastique ki pi lajman itilize.Li ka itilize pou fè pwodwi ki gen gwo dite ak fòs, tankou tiyo ak ekipman, pòt profile, fenèt ak fèy anbalaj.
Li kapab tou fè pwodwi mou, tankou fim, fèy, fil elektrik ak câbles, planche ak kwi sentetik, pa adisyon nan plastifyan.

Materyèl bwit yo itilize pou fè tiyo PVC difisil corrugated prepare soti nan
PVC (100 pts.wt.),
trisalt (6.4-6.8 pts.wt.),
stearat plon (0.42-0.47 pts.wt.),
stearat barium (1.4-1.7 pts.wt.),
asid stearik (0.42-0.47 pts.wt.),
parafine mikrokristal (0.36-0.41 pts.wt.),
sir polyvinyl (0.58-0.62 pts.wt.),
ACR (401) (1.9-2.1 pts.wt.),
polietilèn klorin (5.8-6.3 pts.wt.),
