Iyini i-Ptfe?
I-Polytetrafluoroethylene (I-PTFE) iyi-fluoropolymer yokwenziwa ye-tetrafluoroethylene futhi iyi-PFAS enezinhlelo zokusebenza eziningi.Amakhemikhali abalulekile we-PTFE, izinga lokushisa, umswakama, nokumelana nogesi kuyenza ibe into efanelekile noma nini lapho imikhiqizo, amathuluzi, nezingxenye kudingeka ziqine futhi zithembeke ngisho nasezinhlelweni ezinzima kakhulu.Phezu kwalokhu, i-PTFE inokuqina okuyingqayizivele kwezinga lokushisa eliphansi kanye nokumelana nomlilo okwenza kube ukukhetha okuhle kohlu olukhula njalo lwemikhiqizo, izingxenye, kanye nezinhlelo zokusebenza.
Iyini i-PVC?
I-PVCiyi-polymer yokwenziwa yepulasitiki yesithathu emhlabeni wonke (ngemuva kwe-polyethylene ne-polypropylene). Cishe amathani ayizigidi ezingu-40 ePVC akhiqizwa unyaka ngamunye.
I-PVC ifika iqinile (ngezinye izikhathi ifushaniswa njenge-RPVC) namafomu aguqukayo.I-PVC eqinile isetshenziswa ekwakheni ipayipi, iminyango namafasitela.Ibuye isetshenziswe ekwenzeni amabhodlela epulasitiki, ukupakisha, kanye namakhadi asebhange noma obulungu.Ukwengeza ama-plasticizer kwenza i-PVC ithambe futhi ibe lula.Isetshenziswa ekufakeni amapayipi, ukufaka amakhebula kagesi, ukubeka phansi phansi, izimpawu, amarekhodi egilamafoni, imikhiqizo edonsa umoya, kanye nasezindaweni zenjoloba.Ngokotini noma ilineni, isetshenziselwa ukukhiqizwa kwendwangu.
