Icyerekezo cy'ejo hazaza cya PVC Resin
PVC ni ubwoko bwa pulasitiki ikoreshwa cyane mu bwubatsi. Kubwibyo, ntabwo izasimburwa igihe kirekire mu gihe kizaza, kandi izagira amahirwe menshi yo gukoreshwa mu turere tudateye imbere mu gihe kizaza. Nkuko twese tubizi, hari uburyo bubiri bwo gukora PVC, bumwe ni uburyo mpuzamahanga bwa ethylene busanzwe, ubundi ni uburyo bwihariye bwa karubone ya calcium mu Bushinwa. Inkomoko y'uburyo bwa ethylene ahanini ni peteroli, mu gihe amasoko y'uburyo bwa karubone ya calcium ahanini ari amakara, limestone n'umunyu. Ubu butaka bwiganje cyane mu Bushinwa. Kuva kera, uburyo bwa karubone ya calcium ya PVC mu Bushinwa bwari ku mwanya wa mbere. Cyane cyane kuva mu 2008 kugeza 2014, ubushobozi bwa karubone ya calcium ya PVC mu Bushinwa bwariyongereye, ariko kandi bwazanye ... -
PVC Resin ni iki?
Polyvinyl chloride (PVC) ni polymer yakozwe na vinyl chloride monomer (VCM) muri peroxide, azo compound n'ibindi bintu byatangije cyangwa hakurikijwe uburyo bwa polymerization ya free radical munsi y'urumuri n'ubushyuhe. Vinyl chloride homopolymer na vinyl chloride copolymer byose hamwe byitwa vinyl chloride resin. PVC yigeze kuba pulasitiki nini ku isi ikoreshwa muri rusange, ikaba yarakoreshwaga cyane. Ikoreshwa cyane mu bikoresho by'ubwubatsi, mu nganda, mu bikoresho bya buri munsi, mu ruhu rwo hasi, mu matafari yo hasi, mu ruhu rw'ubukorano, mu miyoboro, mu nsinga n'insinga, mu firime yo gupfunyika, mu macupa, mu bikoresho byo gufuro, mu bikoresho byo gufunga, mu migozi n'ibindi.
