PTFE kav yog ua los ntawm polytetrafluoroethylene (PTFE) cov khoom.
Polytetrafluoroethylene, los yog PTFE luv luv, yog ib tug high-kev ua tau zoo yas, uas yog nto moo rau nws zoo heev tshuaj stability, corrosion kuj, sealing, siab lubrication, tsis adhesion, hluav taws xob rwb thaiv tsev thiab zoo anti-aging endurance. Nws yog ib tug polymer compound polymerized los ntawm tetrafluoroethylene, uas tsis tshua muaj kub kub thiab txias tsis kam thiab yuav siv tau rau lub sij hawm ntev nyob rau hauv qhov kub thiab txias ntawm -180 degree rau +260 degree. Polytetrafluoroethylene yuav luag insoluble nyob rau hauv tag nrho cov kuab tshuaj thiab muaj cov yam ntxwv ntawm acid tsis kam, alkali tsis kam, thiab tsis kam mus rau ntau yam organic solvents, ua rau nws ib tug heev corrosion-resistant khoom. Tsis tas li ntawd, kev sib txhuam coefficient ntawm polytetrafluoroethylene yog qhov tsawg heev, uas tuaj yeem tsis tsuas yog ua cov roj nplua nyeem, tab sis kuj yog cov txheej txheem zoo tshaj plaws rau kev ntxuav yooj yim ntawm cov kav dej sab hauv.
Polytetrafluoroethylene yeeb nkab yog cov kav dej uas tsim los ntawm kev siv tshuab tshwj xeeb, uas tuaj yeem tiv taus siab zoo ntawm 1.6Mpa thiab tsis zoo siab ntawm 77Kpa, thiab tuaj yeem siv tau ib txwm nyob rau hauv qhov kub ntawm -60 degree rau +260 degree . Hom yeeb nkab no tshwj xeeb tshaj yog tsim rau kev thauj cov pa roj thiab cov kua dej hauv qhov kub thiab txias vim nws cov corrosion kuj zoo heev, thiab tsis tuaj yeem hloov tau los ntawm lwm cov khoom siv hauv cov kav dej.
