Yintoni iPtfe?
Polytetrafluoroethylene (PTFE) yi-fluoropolymer eyenziweyo ye-tetrafluoroethylene kwaye yi-PFAS enezicelo ezininzi.Iikhemikhali ezibalulekileyo ze-PTFE, ubushushu, ukufuma, kunye nokuchasana kombane kuyenza ibe yimathiriyeli efanelekileyo nanini na xa iimveliso, izixhobo, kunye namalungu kufuneka aqine kwaye athembeke nakwezona zicelo zinzima.Ngaphezulu koku, i-PTFE iqhayisa ukuqina okuphantsi kobushushu kunye nokumelana nomlilo okwenza kube yinto efanelekileyo yoluhlu olukhulayo lweemveliso, amacandelo, kunye nokusetyenziswa.
Yintoni iPVC?
I-PVCyipolymer yokwenziwa kweplastiki yesithathu ehlabathini lonke (emva kwepolyethylene kunye nepolypropylene). Malunga nezigidi ezingama-40 zeetoni zePVC ziveliswa ngonyaka ngamnye.
I-PVC ifika ngokungqongqo (ngamanye amaxesha ifinyezwa njenge-RPVC) kunye neefom eziguquguqukayo.I-PVC eqinile isetyenziselwa ukwakhiwa kombhobho, iingcango kunye neefestile.Ikwasetyenziswa ekwenzeni iibhotile zeplastiki, ukupakishwa, kunye namakhadi ebhanki okanye obulungu.Ukongeza iiplasticizers kwenza iPVC ibethambile kwaye ibe bhetyebhetye.Isetyenziswa kwimibhobho yamanzi, ukugquma iintambo zombane, ukubeka phantsi phantsi, imiqondiso, iirekhodi zegramafoni, iimveliso ezinokuvutheka, kunye nezinto ezithatha indawo yerabha.Ngekotoni okanye ilinen, isetyenziselwa ukuvelisa i-canvas.
