Polyvinyl chloride (PVC) ni polymer ya vinyl chloride monomer (VCM) polymerized na peroxide, azo compound hamwe nabandi batangije cyangwa hakoreshejwe uburyo bwa radical polymerisation yubusa hakoreshejwe urumuri nubushyuhe. Vinyl chloride homo polymer na vinyl chloride co polymer bita vinyl chloride resin.
PVC yahoze ari plastiki nini nini-rusange muri rusange kandi yarakoreshejwe cyane. Ikoreshwa cyane mubikoresho byubwubatsi, ibicuruzwa byinganda, ibikenerwa bya buri munsi, uruhu rwo hasi, amatafari yo hasi, uruhu rwubukorikori, imiyoboro, insinga ninsinga, firime ipakira, amacupa, ibikoresho bifuro, ibikoresho bifunga kashe, fibre nibindi.
PVC ni amorphous imiterere yifu yera, hamwe nimpamyabumenyi nkeya. Ubushyuhe bwikirahure bwacyo ni 77 ~ 90 ℃, kandi butangira kubora kuri 170 ℃. Hagati aho, ifite umutekano muke wumucyo nubushyuhe: izabora kandi itange hydrogène chloride hejuru ya 100 ℃ cyangwa nyuma yigihe kinini cyizuba, kandi ihita ikora catalitike ihimbye, itera ibara no kugabanuka kumiterere yumubiri nubukanishi, Mubikorwa bifatika , stabilisateur cyangwa ibindi byongeweho bigomba kongerwaho kugirango tunoze ituze rya PVC.
Isosiyete irashobora gutanga munsi yinyongera ya PVC ifuro:
| GUKURIKIRA | UMUSARURO | URUBANZA | UBWOKO BW'IGIHUGU | GUSABA |
| ANTIOXIDANT | YIHOO AN245DW | 36443-68-2 35% 7732-18-5 65% | SONOX 2450DW | Ahanini ikoreshwa muri styrene, reberi yubukorikori, POM homopolymer na copolymer, PU, PA, PET, MBS, na PVC. |
| YIHOO AN333 | 77745-66-5 | JP333E | Antioxydants idafite fenol, ikoreshwa nka stabilisateur yubushyuhe ifasha muri PVC, itezimbere ibara nubucyo bwibicuruzwa bya PVC. Irashobora kandi gukoreshwa mubikoresho bya reberi na PU mugutezimbere gusaza kwibicuruzwa. | |
| YIHOO HP136 | 181314-48-7 | Irashobora gutanga hydrogène ikora kugirango igarure antioxydants ya fenolike ihagaritswe kandi igabanye igipimo cyiyongereye cya AO zombi. Bikwiranye nubushyuhe bwo hejuru bwo gutunganya, PP, ibikoresho bya BOPP membrane, ibikoresho bya PC bisobanutse neza, ibikoresho bya styrene, ibikoresho bya PPR, TPU, ibifata, nibindi. |
Kugirango utange inyongeramusaruro za porogaramu mubisobanuro byihariye, isosiyete yashyizeho urutonde rwibicuruzwa bikubiyemo porogaramu zikurikira: PA polymerisation & modifisiyonike, inyongera ya PU ifuro, inyongera ya PVC polymerisation & modifisiyonike, inyongera za PC, inyongera ya TPU elastomer, inyongeramusaruro nke za VOC inyongeramusaruro, inyongeramusaruro, inyongeramusaruro, API nibindi bicuruzwa nkimiti nka zeolite nibindi ..
Buri gihe urahawe ikaze kutwandikira kugirango ubaze ibibazo!
