INzululwazi ngasemva kwe-PTFE iFabric eNgqunyiweyo
Ukubunjwa kwemichiza kunye neePropati
Ilaphu eligqunywe yi-PTFE yimathiriyeli edityanisiweyo equlathe i-fiberglass substrate eqatywe nge-polytetrafluoroethylene. I-fiberglass core inika amandla kunye nokuzinza kwe-dimensional, ngelixa i-PTFE yokugqoka inika iikhemikhali ezikhethekileyo kunye neepropati ezibonakalayo. I-PTFE, i-synthetic fluoropolymer ye-tetrafluoroethylene, idume ngokunganamatheli kunye neempawu ze-hydrophobic. Le ndibaniselwano iphumela kwilaphu elingomelelanga nje kuphela kodwa elikwaziyo ukumelana noluhlu olubanzi lweekhemikhali, izinyibilikisi, kunye nezinto ezisingqongileyo.
Inkqubo yokuVelisa
Ukuveliswa kwelaphu eligqunywe nge-PTFE kubandakanya inkqubo yokuvelisa ephucukileyo. Okokuqala, ilaphu le-fiberglass ekumgangatho ophezulu licocwa ngobuchule kwaye lilungiswe. Emva koko, iileya ezininzi ze-PTFE zisetyenziswa ngenkqubo eyodwa yokwaleka. Oku kunokubandakanya ubuchule obunjengokwaleka kwediphu, ukugquma kweemela, okanye ukugquma ngesitshizi. Ilaphu eligqunyiweyo liphantsi kwenkqubo yokufudumala elawulwa ngononophelo, eyenza i-sinters ye-PTFE particles, idale indawo egudileyo, eqhubekayo.
