Ptfe Niki?
Polytetrafluoroethylene (PTFE) ni fluoropolymer ya syntetique ya tetrafluoroethylene kandi ni PFAS ifite progaramu nyinshi.Imiti ikomeye ya PTFE, ubushyuhe, ubushuhe, hamwe n’amashanyarazi birwanya ibintu byiza igihe cyose ibicuruzwa, ibikoresho, nibigize bigomba kuba biramba kandi byizewe no mubikorwa bikomeye.Hejuru yibi, PTFE ifite uburebure budasanzwe bwo kwihanganira ubushyuhe no kurwanya umuriro bigatuma ihitamo neza kurutonde rwibicuruzwa bikomeza kwiyongera, ibice, nibisabwa.
PVC ni iki?
PVCni iya gatatu ku isi ikorwa cyane na polimeri ya syntetique ya plastike (nyuma ya polyethylene na polypropilene) .Toni zigera kuri miliyoni 40 za PVC zikorwa buri mwaka.
PVC iza muburyo bukomeye (rimwe na rimwe mu magambo ahinnye nka RPVC) nuburyo bworoshye.PVC Rigid ikoreshwa mubwubatsi bwa pipe, inzugi na Windows.Irakoreshwa kandi mugukora amacupa ya pulasitike, gupakira, na banki cyangwa amakarita yabanyamuryango.Ongeramo plasitike ituma PVC yoroshye kandi ihinduka.Ikoreshwa mumazi, insinga z'amashanyarazi, hasi, ibyapa, inyandiko za fonografi, ibicuruzwa byaka, no mubisimbuza reberi.Hamwe na pamba cyangwa imyenda, ikoreshwa mugukora canvas.
