PTFE khoom
PTFE luv luv rau polytetrafluoroethylene thiab muaj ntau yam zoo:
nws zoo heev corrosion kuj ua rau nws muaj peev xwm tiv taus ze li ntawm tag nrho cov muaj zog acids (xws li aqua regia)
nws cov rwb thaiv tsev muaj zog ua kom nws tsis txhob cuam tshuam los ntawm ib puag ncig thiab zaus, thiab qhov ntim tsis kam tuaj yeem ncav cuag 1018 ohms / cm, tsis tshua muaj hluav taws xob poob thiab siab tawg voltage;
PTFE cov ntaub ntawv kuj muaj zoo heev kub thiab tsis kub tsis kam, thiab tsis muaj kev cuam tshuam qhov kub thiab txias hloov, usable ua hauj lwm kub -190degree~ 250degree;
PTFE cov khoom muaj nws tus kheej-lubricating zog, nrog tsawg tshaj kev sib txhuam coefficient nyob rau hauv cov khoom, nws yog ib tug zoo tagnrho roj-dawb lubricating khoom, thiab yuav siv tau raws li roj-dawb bearing, thiab lwm yam .;
Ntxiv rau qhov ntawd, PTFE nto tsis nplaum. Raws li kev tshawb nrhiav, cov khoom siv paub zoo tsis tuaj yeem ua raws li qhov chaw, thiab nws yog cov khoom siv nrog lub zog me tshaj plaws;
PTFE cov ntaub ntawv kuj muaj cov atmospheric aging kuj zoo, hluav taws xob tsis kam thiab permeability tsawg, thiab nws raug rau huab cua nyob rau lub sij hawm ntev, cov khoom nto tsis hloov, nrog rau cov incombustibility ntawm PTFE cov ntaub ntawv, thiab cov pa txwv index yog qis dua 90. . Yog tias cov nplaim taws qhib raug tshem tawm, cov khoom siv PTFE yuav tsis raug puas tsuaj, nws yuav hlawv mus ntxiv.
Tab sis nws tsim nyog pom tias txawm tias cov khoom siv PTFE tsis muaj tshuaj lom thiab muaj kev nyab xeeb, thaum nws yuav tso cov pa phem thaum qhov kub siab tshaj 380.degreelos yog qhib nplaim taws, uas xav kom peb yuav tsum xyuam xim rau.
