Ntawm cov xim tha xim siv nyob rau hauv txhuas phaj, fluorocarbon resin muaj qhov tshwj xeeb zoo tshaj plaws: huab cua tsis kam, tiv tshav kub, tsis kam tiv taus kub, tshuaj lom neeg tsis kam, thiab tshwj xeeb tsis-lo thiab tsis tshua muaj kev sib txhuam. Cov yam ntxwv zoo no ua rau fluorocarbon resin siv dav hauv ntau qhov chaw xws li kev tsim kho, tshuaj lom neeg kev lag luam, hluav taws xob thiab hluav taws xob kev lag luam, tshuab kev lag luam, aerospace kev lag luam, khoom siv hauv tsev thiab lwm yam.
1. Hom roj fluorocarbon cob
Feem ntau cov neeg hauv fluorocarbon resin tsev neeg yog PVDF thiab FEVE.
PVDF yog polyvinylidene fluoride cob, uas tau tshwm sim nyob rau xyoo 1960 thiab feem ntau yog siv los ua lub tsev txheej rau cov hlau cov phaj ua kom zoo nkauj tiv thaiv txheej txheem. Tom qab peb caug xyoo ntawm kev sim tiag, tusqub tsos yog yeej tswj. Cov fluorocarbon-coated hlau ci xim hom yuav tsum hla dhau qhov kub kub los ua ib zaj duab xis, thiab tsis tuaj yeem thov rau qhov kub tsis txias.
FEVE, uas yog polychlorotrifluoroethylene / vinyl ether resin, tau zoo tsim los ntawm cov kws tshawb fawb Nyij Pooj xyoo 1982 siv cov qauv tsim molecular saw thiab cov thev naus laus zis tshuab.
Nws yog cov tshuaj fluorocarbon txheej uas tuaj yeem kho ntawm qhov chaw sov. Thaum lub cev kub tsis txias, cov tshuaj fluorocarbon txheej txheem ua rau saum npoo ntawm ntau cov substrates los ntawm kev txhuam, cov hlau rau txheej, txau thiab lwm cov txheej txheem feem ntau los ua cov tshuaj fluorocarbon tiv thaiv txheej, uas zoo heev nthuav dav ntawm cov kev thov ntawm fluorocarbon txheej. Fluorocarbon txheej txheej hauv lub neej txhua hnub.
2. Cov yam ntxwv ntawm fluorocarbon cob
Cov tshuaj fluorocarbon txheej rau cov ntaub thaiv phab ntsa txheej txheej yog hom organic txheej raws fluorocarbon resin, nrog cov ntawv xov hlau lossis mica siv lead ua toner, thiab nws cov ntsiab lus PVDF (polyvinylidene fluoride) yog 70% (resin Mass ratio) saum toj no. Cov qauv ua tshuaj lom neeg ntawm fluorocarbon puag khoom yog sib khi los ntawm fluorine / carbon chemical bond, uas yog suav hais tias yog qhov tseem ruaj khov thiab qhov muaj zog tshaj plaws tam sim no. Nyob rau hauv ib txwm muaj xwm txheej, nws muaj cov haujlwm zoo nram qab no:
Kev tiv thaiv huab cua - nws muaj peev xwm tiv taus huab cua tsis zoo thiab ultraviolet sab, yog li nws tuaj yeem tswj cov xim thiab ci rau lub sijhawm ntev;
Kev tiv thaiv xeb - nws tiv taus cov kua qaub thiab kua alkali thiab tsis cuam tshuam los ntawm huab cua paug thiab dej nag. Lub permeability ntawm oxygen, noo noo thiab corrosive hais yog qhov tsawg, thiab nws tuaj yeem tiv taus qhov chaw ib puag ncig ntev ntev uas tsis muaj xeb.
Neeg kho tshuab cov khoom - zoo heev cuam tshuam, hnav tsis kam thiab zoo xim zaj duab xis yooj.
Hauv txheej txheej npe hu ua KYNAR500®, qhov yuav tsum hnyav ntawm qhov hnyav ntawm KYNAR500 ® yog ≥70%. Qhov laj thawj yog tias thaum cov ntsiab lus resin yog 70%, kev ua tau zoo ntawm PVDF, tshwj xeeb tshaj yog huab cua tiv thaiv thiab ua tau ntev, tuaj yeem ua tau raws li cov kev xav tau ntau dua, thiab thaum nws siab tshaj 70%, nws qhov kev cuam tshuam tsis loj, yeej 70% Hauv tib yam kev ua haujlwm hauv lub xeev, thiab cov ntsiab lus tseem ceeb yog 30% thiab 70% PVDF phim, qhov kev ua tau zoo tshaj plawsKYNAR500®resin cov ntsiab lus tsawg dua 70%, lub npe KYNAR500®coating tsis tso cai.
3. Txheej txheem ntawm fluorocarbon resin xim pleev xim
Muaj ntau txoj hau kev rau fluorocarbon cob txheej, uas tuaj yeem yog cov hlau ua cov roj pleev, tshuaj pleev xim txheej lossis electrostatic hmoov txheej. Cov txheej txheem sib txawv yuav tsum muaj cov khoom siv sib txawv thiab cov txheej txheem kho, thiab qhov tshwm sim ntawm cov xim txheej thiab txheej xim kuj sib txawv.
