1. Teflon zaj duab xis, tseem hu ua PTFE zaj duab xis, Teflon zaj duab xis, los yog f4 zaj duab xis, yog ua los ntawm tshem tawm PTFE resin los ntawm molding, sintering, txias rau hauv ib qho khoob, thiab ces tig thiab calendering. Cov yeeb yaj kiab tsim los ntawm kev tig yog cov yeeb yaj kiab uas tsis yog kev taw qhia, thiab cov yeeb yaj kiab uas tsis yog taw qhia yuav ua rau cov yeeb yaj kiab taw qhia tom qab calendering. Cov zaj duab xis uas tsis yog-oriented yog dov 1.1-1.8 zaug los ua ib zaj yeeb yaj kiab ib nrab. Teflon zaj duab xis yog siv los ua qhov nruab nrab ntawm lub capacitor, xws li rwb thaiv tsev, hluav taws xob ntsuas hluav taws xob, thiab cov khoom siv ntom ntom. Nws muaj crystallinity siab, nruj txheej txheem molecular orientation, thiab me porosity, yog li Teflon zaj duab xis tau zoo heev. PTFE zaj duab xis muab faib ua PTFE xim zaj duab xis, PTFE activation zaj duab xis thiab F46 zaj duab xis. PTFE xim zaj duab xis yog tsim los ntawm ncua PTFE resin thiab ntxiv ib co xim ntawm cov xim, ces molded thiab sintered ua ib tug dawb paug, ces tig thiab calendered ua liab, ntsuab, xiav, daj, ntshav, xim av, dub, txiv kab ntxwv 13 xim ntawm PTFE directional lossis tsis-directional xim zaj duab xis. Polytetrafluoroethylene xim zaj duab xis tseem muaj hluav taws xob zoo rwb thaiv tsev tom qab ntxiv qee qhov xim xim, thiab tsim nyog rau kev rwb thaiv tsev thiab kev faib tawm ntawm cov xov hlau, cables, thiab cov khoom siv hluav taws xob. Txawm hais tias PTFE xim zaj duab xis yog ntxiv nrog rau qee qhov xim xim, nws tseem muaj cov hluav taws xob zoo, uas yog tsim rau kev rwb thaiv tsev thiab kev faib tawm ntawm cov xov hlau, cables, thiab cov khoom siv hluav taws xob. PTFE activation zaj duab xis yog ib zaj duab xis ua los ntawm PTFE zaj duab xis, puv zaj duab xis thiab xim zaj duab xis, thiab tom qab ntawd ces deg activation kho. Pigment, iav fiber ntau, carbon fiber, graphite, bronze hmoov thiab lwm yam muab ntxiv rau cov khoom, thiab qhov kev ua tau zoo ntxiv tom qab kev kho kom ua haujlwm. Nws tuaj yeem sib xyaw nrog cov roj hmab, hlau, thiab lwm yam, thiab tseem tuaj yeem siv los ua cov kab xev tshwj xeeb kom tau raws li cov qauv tsim. Dav siv nyob rau hauv lub teeb kev lag luam, tub rog kev lag luam, aerospace, roj teb thiab lwm yam teb. F4 zaj duab xis muaj qhov zoo ntawm qhov tseem ceeb tshaj qhov hluav taws xob tiv thaiv thiab tawg voltage. Nws yog siv los ua qhov nruab nrab capacitor, xws li rwb thaiv tsev, hluav taws xob ntsuas hluav taws xob, thiab sealing gasket. PTFE tig zaj duab xis yog ib hom kev taw qhia zaj duab xis tsim los ntawm dov thiab taw qhia los ntawm cov yob kub nrog lub calender. Nws muaj crystallinity siab, molecular orientation yog nruj nreem kaw, thiab lub porosity yog me me, yog li cov PTFE zaj duab xis tau zoo heev, tshwj xeeb tshaj yog yog qhov voltage kuj yog pom tseeb dua.
2. Qhov sib txawv ntawm nylon thiab PTFE Polytetrafluoroethylene (PTFE, feem ntau hu ua Teflon, yas huab tais) yog cov yeeb nkab tshwj xeeb ua tom qab extrusion thiab sintering, ziab, high-temperature sintering, thiab shaping. Teflon tseem hu ua Teflon, Teflon, Teflon, Teflon, Teflon, PTFE, yas vaj ntxwv, Teflon hauv lus Askiv, dav siv hauv tshuab, khoom siv hluav taws xob, tsheb, aerospace, tshuaj lom neeg kev lag luam, khoos phis tawj, hluav taws xob cua sov, tub rog, kev sib txuas lus thiab lwm yam tseem ceeb technology. kev lag luam, xws li micro-transformers. Nylon tau tsim los ntawm tus kws tshawb fawb Asmeskas zoo tshaj Carothers thiab pab pawg tshawb fawb hauv nws cov thawj coj. Nws yog thawj cov hluavtaws fiber ntau hauv ntiaj teb.
Cov tsos ntawm nylon tau coj ib tug tshiab saib rau textiles, thiab nws synthesis yog thawj kauj ruam nyob rau hauv hluavtaws fiber ntau.
Ib qho kev tawg loj hauv kev lag luam, tab sis kuj tseem yog ib qho tseem ceeb hauv kev lag luam polymer chemistry. Qhov ntom ntawm polytetrafluoroethylene feem ntau yog ntau dua 2, thaum qhov ceev ntawm nylon yog li 1.2. Qhov ntom ntawm polytetrafluoroethylene yog qhov ntom ntom, thiab nws qhov kub tsis kam thiab hardness kuj zoo dua, thaum lub raj nylon yog softer, thiab nws qhov kub thiab txias tsis kam yog phem dua li ntawm polytetrafluoroethylene hlab, tab sis vim nws kuj yog mos, nws tuaj yeem hloov mus rau ntau thaj chaw. Nyob rau hauv cov nqe lus ntawm tus nqi, PTFE hlab yog me ntsis kim tshaj li nylon hlab. Cov yam ntxwv ntawm PTFE cov khoom 1. Cov tshuaj lom neeg muaj zog: tuaj yeem tiv taus txhua yam muaj zog acids, suav nrog aqua regia, hydrofluoric acid, concentrated hydrochloric acid, nitric acid, oleum, organic acids, thiab lwm yam, muaj zog alkalis, muaj zog oxidants, txo cov neeg ua haujlwm thiab lub luag haujlwm ntawm ntau yam organic solvents. Zoo tagnrho rau siab purity chemical feed applications. 2. Tsis tshua muaj kev sib txhuam coefficient: Cov kev sib txhuam coefficient feem ntau tsuas yog 0 xwb. 3 3. Cov khoom tiv thaiv zoo heev, thiab cov phab ntsa sab hauv ntawm lub raj tsis yooj yim rau kev ua raws li colloids thiab tshuaj. 4. Kev laus zoo heev, tuaj yeem siv sab nraum zoov ntev. 5. Kev ua tau zoo ntawm cov hluav taws xob rwb thaiv tsev: PTFE yog cov khoom siv tsis zoo nrog cov khoom siv hluav taws xob zoo, tsis tshua muaj hluav taws xob, thiab cov dielectric tsis tu ncua ntawm li 2.0, uas yog qhov tsawg tshaj plaws ntawm cov khoom siv hluav taws xob insulating. 6. Qee lub raj muaj qhov pom tseeb siab, uas ua rau nws yooj yim rau kev soj ntsuam cov kua dej sab hauv.
