Dab tsi yog qhov zoo tshaj plaws symmetrical thiab unbranched linear polymer?

Lub npe lus Askiv tag nrho rau polytetrafluoroethylene yas yog Polytetrafluoroethylene, abbreviated li Teflon, PTFE, F4, thiab lwm yam; Suav lub npe suav nrog "Plastic King", "Teflon", "Teflon", "Teflon", thiab lwm yam. Lub tshuab hluav taws xob Teflon tsim los ntawm peb lub Hoobkas muaj kev ruaj ntseg tshuaj lom neeg. Nws cov qauv molecular yog ib qho symmetrical linear polymer tsis muaj branched chains. Nws cov tshuaj lom neeg kev ua tau zoo yog qhov ruaj khov, thiab nws muaj kev nyab xeeb hauv cov kua qaub uas muaj zog, muaj zog hauv paus, oxidants, oxides, aqua regia thiab lwm yam kev daws teeb meem rau lub sijhawm ntev; Thiab muaj peev xwm tiv taus hydrofluoric acid nrog ib qho concentration ntawm 0-100 feem pua ​​boiling.
(1) Thaum siv cov ziab qhuav, xav txog seb qhov teeb tsa hluav taws xob puas tsim nyog: seb puas muaj lub zog tsim nyog tau raug xaiv raws li qhov tseeb ntawm tus kheej. Yog hais tias lub hwj chim load yog siab dhau lawm, nws yuav ua rau lub cua sov raj kub.
(3) Lub tshuab hluav taws xob cua sov yog tsim los ua kom sov cov kua dej thiab yuav tsum tsis txhob hlawv kom qhuav yam tsis tau tawm hauv cov kua dej thaum lub sijhawm ua haujlwm. Tiv thaiv kom tsis txhob muaj cua kub thiab hlawv tawm ntawm hluav taws xob cua sov raj. Lub zog tsis tshua muaj qhov chaw tsis muaj zog yog ib qho ntawm ob peb paub cov khoom siv nrog lub zog me me uas tsis muaj zog. Yuav luag txhua qhov xov xwm tsis tuaj yeem ua raws li lawv qhov chaw, thiab tsis muaj av tsim tawm thaum siv. Teflon hluav taws xob cua sov raj yog tsim los ntawm lub cev thiab tshuaj lom neeg cov khoom ntawm cov khoom siv fluoroplastic zoo, nrog rau kev txhim kho cov ntaub ntawv. Nws yog tsim rau cua sov ntau yam muaj zog acid thiab alkali kua. Hluav taws xob cua sov raj muaj kev laus ua haujlwm zoo thiab kev ua haujlwm winding. Lub taub hau xovxwm yog kaw tag nrho, thiab qhov tsis muaj cua sov thiab overheating kub tswj qhov system tuaj yeem kho raws li qhov xav tau. Lub tshuab hluav taws xob Teflon tau txais kev hloov pauv ntawm qhov chaw qis (1.5w / cm2), uas ua rau qhov kub thiab txias ntawm Teflon hluav taws xob cua sov raj qis dua qhov tseem ceeb ntawm cov organic compound decomposition. Nws ua kom lub purity ntawm lub cua sov raj thiab additives, thiab hluav taws xob cua sov raj nws tus kheej yog tsis yooj yim rau hlawv, nrog ib tug series ntawm zoo heev kev ua tau zoo xws li lub neej ntev kev pab cuam, tag nrho sealing, tsis corrosion, thiab tsis muaj to.
(2) Thaum lub sijhawm ua haujlwm ntawm lub tshuab hluav taws xob cua sov, nyob ntawm cov kua nruab nrab hauv kev sib cuag, tej zaum yuav muaj cov nplai, av, thiab cov khib nyiab pov tseg rau ntawm qhov chaw ntawm lub tshuab hluav taws xob cua sov, uas tuaj yeem cuam tshuam cov hluav taws xob cua sov raj thiab cuam tshuam rau nws cov cua sov. dissipation, ua rau kev puas tsuaj rau hluav taws xob cua sov raj. Yog li ntawd, nws raug nquahu kom siv cov kua dej tawm uas tau kho thiab muaj cov impurities tsawg dua. Tsis tu ncua ntxuav lub ntsej muag ntawm lub raj cua sov thiab sab hauv ntawm lub thawv kom txhim kho kev ua haujlwm zoo thiab kev pabcuam lub neej ntawm lub raj cua sov.
