Kev xaiv cov ntaub ntawv txheej rau xim hlau coils

Tam sim no, hom coatings siv rau xim coated steel daim hlau muaj xws li polyester coatings / fluorocarbon coatings / silicon hloov coatings / high weather resistant coatings / acrylic coatings / polyurethane coatings / plastisol txheej, thiab lwm yam.
1, Polyester txheej muaj adhesion zoo rau cov ntaub ntawv, thiab xim coated steel daim hlau yog ib qho yooj yim rau txheej txheem thiab daim ntawv, nrog tus nqi qis, ntau yam khoom, thiab ntau yam xim xaiv. Tshaj tawm ncaj qha rau hauv ib puag ncig, lub neej tiv thaiv corrosion tuaj yeem ncav cuag li 7-8 xyoo. Txawm li cas los xij, nyob rau hauv ib puag ncig kev lag luam lossis thaj chaw muaj kuab paug hnyav, lawv lub neej kev pabcuam yuav luv luv. Txawm li cas los xij, UV tsis kam thiab zaj duab xis crushing tsis kam ntawm polyester txheej tsis zoo tagnrho. Yog li ntawd, kev siv PE txheej tseem yuav tsum tau txwv. Nws feem ntau yog siv rau hauv thaj chaw uas muaj huab cua tsawg lossis cov khoom lag luam uas xav tau ntau yam molding thiab kev ua haujlwm.
2, Vim tias muaj cov pab pawg nquag - OH / - COOH hauv polyester, nws yooj yim rau hnov ​​​​mob nrog lwm cov macromolecules thiab polymers. Txhawm rau txhim kho lub teeb ua haujlwm thiab ua kom tsis muaj zog ntawm PE, silicone resin nrog cov xim zoo nkauj thiab kub tsis kam yog siv rau cov tshuaj tiv thaiv denaturation, thiab tus nqi denaturation nrog PE tuaj yeem nyob nruab nrab ntawm 5% -50%. SMP muab kev ua haujlwm zoo dua ntawm cov hlau phaj, nrog rau lub neej corrosion mus txog rau 10-12 xyoo. Tau kawg, nws tus nqi kuj tseem siab dua PE, tab sis vim yog qhov tsis zoo ntawm cov nplaum thiab ua cov txheej txheem ntawm silicone resin rau cov khoom, SMP xim coated steel daim hlau tsis haum rau cov xwm txheej uas xav tau ntau yam txheej txheem molding, thiab feem ntau yog siv rau lub tsev ru tsev. thiab sab nrauv phab ntsa.
3, Cov huab cua resistant polyester txheej yog superior rau zoo tib yam silicon hloov polyester txheej, nrog rau sab nraum zoov huab cua tsis kam mus txog 15 xyoo. Nyob rau hauv tus txheej txheem ntawm synthesizing huab cua resistant polyester resin, monomers uas muaj cyclohexane qauv yog siv los ua kom tiav qhov sib npaug ntawm resin yooj, huab cua tsis kam, thiab nqi. Aromatic polyols thiab polybasic acids yog siv los txo qhov nqus ntawm ultraviolet rays los ntawm resin thiab ua tiav huab cua tsis kam ntawm txheej. Ntxiv ultraviolet absorbers thiab qhov chaw thaiv amines (HALS) rau cov xim tsim los txhim kho huab cua tsis kam ntawm cov xim zaj duab xis.
4, Plastisols muaj dej zoo thiab tshuaj lom neeg. Feem ntau, nws yog cov txheej txheem siab nrog cov txheej tuab ntawm 100-300 μ M. Cov txheej txheem PVC du lossis embossing kho raws li embossing txheej tuaj yeem muab tau; Vim qhov tseeb tias PVC txheej yog cov thermoplastic resin nrog cov yeeb yaj kiab siab, nws tuaj yeem muab kev tiv thaiv zoo rau cov hlau phaj. Tab sis PVC muaj qhov tsis zoo thaum tshav kub kub.
5, Vim yog lub zog sib txuas ntawm PVDF cov khoom siv tshuaj, cov txheej txheem muaj kev tiv thaiv zoo heev thiab cov xim tuav. Nws yog cov khoom lag luam zoo tshaj plaws hauv Baosteel kev tsim kho xim hlau phaj coil txheej, nrog lub siab molecular hnyav thiab cov qauv sib txuas ncaj qha. Yog li ntawd, ntxiv rau cov tshuaj tiv thaiv, nws cov khoom siv kho tshuab, UV tsis kam, thiab kub ua haujlwm kuj tseem ceeb heev. Nyob rau hauv ib puag ncig, lub neej tiv thaiv corrosion tuaj yeem ncav cuag li 20-25 xyoo. Nyob rau hauv xyoo tas los no, fluorine resin co polymerized nrog trifluoroethylene thiab vinyl ester monomers tau dav siv nyob rau hauv Suav teb thiab yog dav siv nyob rau hauv lub tsev sab nrauv phab ntsa thiab hlau panels. Vim yog kev siv yooj yim hydrolyzed vinyl ester monomers, cov ntsiab lus fluorine yog li 30% qis dua PVDF, thiab nws cov huab cua kuj txawv me ntsis ntawm PVDF.
6, Acrylic resin muaj kev ua haujlwm zoo thiab tus nqi siab, thiab tsuas yog siv rau hauv thaj chaw tshwj xeeb (xws li ntim khoom).
