PVC VS PTFE

Kodi Ptfe Ndi Chiyani?

Polytetrafluoroethylene (PTFE) ndi fluoropolymer yopanga ya tetrafluoroethylene ndipo ndi PFAS yomwe ili ndi ntchito zambiri.PTFE chofunika kwambiri mankhwala, kutentha, chinyezi, ndi kukana magetsi kupanga zinthu abwino nthawi iliyonse mankhwala, zida, ndi zigawo zikuluzikulu ayenera kukhala cholimba ndi odalirika ngakhale ntchito zolemetsa kwambiri.Pamwamba pa izi, PTFE ili ndi kukhazikika kwapadera kwa kutentha komanso kukana moto komwe kumapangitsa kukhala chisankho chabwino pamndandanda womwe ukukula nthawi zonse wazinthu, zigawo, ndi ntchito.

PVC ndi chiyani?

Zithunzi za PVCndi yachitatu padziko lonse lapansi yopangidwa mofala kwambiri polima yapulasitiki (pambuyo pa polyethylene ndi polypropylene). Pafupifupi matani 40 miliyoni a PVC amapangidwa chaka chilichonse.

PVC imabwera molimba (nthawi zina imafupikitsidwa ngati RPVC) komanso mawonekedwe osinthika.PVC yolimba imagwiritsidwa ntchito pomanga chitoliro, zitseko ndi mazenera.Amagwiritsidwanso ntchito popanga mabotolo apulasitiki, zopakira, ndi makhadi akubanki kapena umembala.Kuwonjezera mapulasitiki kumapangitsa PVC kukhala yofewa komanso yosinthika.Amagwiritsidwa ntchito popanga mipope, kutsekereza chingwe chamagetsi, pansi, zikwangwani, zojambulira za phonograph, zinthu zowotcha, komanso m'malo mwa rabala.Ndi thonje kapena nsalu, amagwiritsidwa ntchito popanga nsalu.
