Lub sijhawm lav yog ib qho tseem ceeb ntawm cov khoom lag luam uas yuav tsum muaj.Lub sijhawm lav yog lub sijhawm rau kev lees paub zoo.Nws yog ib hom kev ruaj ntseg zoo rau cov khoom nyob rau hauv ib lub sij hawm teev.Tib yam muaj tseeb rau cov khoom PTFE.Txawm hais tias peb txhua tus paub tias PTFE cov khoom muaj lub neej ua haujlwm ntev, kev pabcuam lub neej ntev npaum li cas?Ntau tus neeg yuav tsis paub ntau txog nws.Yog li, cia peb coj PTFE pawg thawj coj ua piv txwv los qhia rau koj Qhia txog kev pabcuam lub neej ntawm PTFE cov khoom.
Kev pab lub neej ntawm lubPTFE ntawvNws yog qhov ntev heev, vim tias daim ntawv PTFE yog lub phaj zoo li PTFE cov khoom ua tiav los ntawm cov txheej txheem tshwj xeeb (lossis tuag txiav lossis tig) los ntawm cov khoom siv PTFE, thiab cov khoom siv PTFE nws tus kheej Nws yog cov khoom siv nrog ntau yam kev ua tau zoo, suav nrogkub tsis kam, uas tuaj yeem siv rau ntawm qhov kub ntawm 200 ~ 260 degrees rau lub sijhawm ntev;tsis kub tsis kam, txawm tias ntawm -100 degrees, PTFE cov khoom tseem mos;corrosion kuj, tuaj yeem tiv taus aqua regia Thiab tag nrho cov organic solvents;huab cua tsis kam, lub sij hawm ntev raug rau huab cua, qhov chaw thiab kev ua haujlwm tsis hloov pauv, nws cov hluav taws xob tiv thaiv thiab tsis tshua muaj permeability kuj zoo dua;siab lubrication, nrog me me coefficient ntawm kev sib txhuam hauv plastics, Lub coefficient ntawm kev sib txhuam tsuas yog 0.04;nws muaj qhov nro me me hauv cov khoom siv thiab tsis ua raws li cov khoom siv;nws yog physiologically inert thiab non-toxic;Cov khoom siv hluav taws xob zoo heev, nws yog ib qho zoo tagnrho Class C insulating cov ntaub ntawv, thiab ib txheej tuab ntawm cov ntawv xov xwm tuaj yeem thaiv qhov siab voltage ntawm 1500V;... Yog li ntawd, qhov zoo ntawm PTFE daim ntawv ua los ntawm PTFE khoom yog ruaj khov nyob rau hauv ib txwm muaj xwm txheej, uas yog qhov zoo tshaj plaws ruaj khov ntawm PTFE daim ntawv teev nyob rau hauv feem ntau cov phau ntawv los yog hauv Internet.Peb tsis lees paub cov yam ntxwv, tab sis peb tseem yuav tsum tau piav qhia lwm yam yam ntxwv ntawm tusPTFE ntawvuas yuav tsum tau piav qhia.
Txhua yam khoom yuav nthuav dav thiab cog lus nrog cua sov, thaum daim ntawv PTFE muaj ntau dua rau thermal expansion thiab contraction, thiab expansion coefficient ntawm PTFE ntawv yog li kaum npaug ntawm cov hlau.Yog li ntawd, thaum daim ntawv PTFE raug hloov mus rau qhov kub thiab txias, nws yuav muaj qhov cuam tshuam loj heev ntawm daim ntawv PTFE, xws li caij nplooj ntoos hlav, caij ntuj sov, caij nplooj zeeg thiab lub caij ntuj no.Hauv ntau qhov chaw ntawm peb lub teb chaws, qhov kub thiab txias sib txawv ntawm plaub lub caij yog qhov loj.Nyob rau hauv lub caij nplooj ntoos hlav, lub caij ntuj sov, lub caij nplooj zeeg thiab lub caij ntuj no, lub rooj tsavxwm kuj tau txais loj los yog me me, thiab qhov teeb meem no tshwm sim.Nws yog ib qho tsim nyog sau cia tias txawm hais tias daim ntawv PTFE yuav raug me ntsis deformed los ntawm kev cuam tshuam ntawm tshav kub thiab txias, nws qhov zoo ntawm lub cev yuav tsis hloov.yuav hloov.
Daim ntawv PTFE tshiab QB/T5257-2018 qhia meej meej tias lub sijhawm lav ntawm PTFE nplooj ntawv yog kaum xyoo.Nov yog thawj zaug uas lub sijhawm lav ntawm PTFE cov khoom tau suav nrog hauv cov qauv kev lag luam hauv tebchaws.
