Lub tshuab nqus tsev plating hluav taws xob cua sov raj UV xim tuaj yeem tiv taus lub teeb ultraviolet

Ib qho tsis txaus ntawm PC yas yog tias nws tsis tiv taus lub teeb ultraviolet, nws yooj yim rau daj thiab hnub nyoog nyob rau hauv lub hnub, thiab nws tsis hnav-resistant. Raws li lub tsheb teeb lub teeb ntxoov ntxoo, cov khoom siv yuav tsum muaj kev tiv thaiv UV zoo, thiab nyob rau hauv lub ntsej muag ntawm qhov teeb meem no, UV topcoat feem ntau yog txau rau ntawm PC yas. UV pleev xim tsim cov dawb radicals nyob rau hauv irradiation ntawm ultraviolet lub teeb, thiab cov tshuaj tiv thaiv resin tshwm sim. Hauv lwm lo lus, thaum lub hnub ci, cov xim pleev xim yog tsim. UV pleev xim yog tiv taus lub teeb ci ultraviolet, thiab txau rau ntawm qhov chaw ntawm cov khoom uas tsis tiv taus lub hnub ci tuaj yeem txuas ntxiv cov khoom siv los tiv thaiv ultraviolet lub teeb, kom cov khoom tsis yooj yim rau hnub nyoog. Tsis tas li ntawd, UV pleev xim zaj duab xis muaj siab hardness, hnav tsis kam thiab siab transparency, uas ua rau lub shortcomings ntawm PC plastics thiab ua tau raws li qhov yuav tsum tau ntawm nws siv raws li ib tug tsheb taillight lampshade.

Hydroxychlorinated polypropylene copolymer rau lub tshuab nqus tsev electroplating hluav taws xob cua sov raj

PP tus neeg saib xyuas kev kho mob yog tshwj xeeb hydroxychlorinated polypropylene copolymer. Nws yog siv nyob rau hauv cov txheej txheem txau ntawm PP cov ntaub ntawv, hloov kho PP cov ntaub ntawv, lwm yam ntaub ntawv, thiab lwm yam. Nws tuaj yeem txhim kho cov wettability thiab nto adhesion ntawm PP substrates. Ib txheej ntawm zaj duab xis yog tsim los ntawm cov xim pleev xim, uas yog sib xyaw ua ke kom ua tiav cov kev sib txuas txaus, yog li txhawb cov interlayer adhesion ntawm cov xim thiab cov khoom PP, tsim cov txheej ruaj khov, thiaj li daws tau qhov teeb meem ntawm cov tshuaj tsuag. los ntawm kev adhesion tsis zoo. Kev tsis xws luag xws li xim tev.

Lub tshuab nqus tsev electroplating hluav taws xob cua sov raj yog coated rau saum npoo ntawm cov khoom thiab ces txau nrog xim

Nylon, PP thiab lwm yam ntaub ntawv yas yog feem ntau ua rau txheej adhesion teeb meem. Ntawm qhov tod tes, nws yog qhov teeb meem ntawm qhov tsis muaj polarity thiab qis zog saum npoo. Ntawm qhov tod tes, siab crystallinity thiab kev hloov pauv ntawm cov khoom siv hauv kev ua lag luam thiab lwm yam khoom siv yuav ua rau cov khoom siv tsis zoo, ua rau cov khoom tsis muaj zog adhesion. Ntawm cov khoom siv hlau, xws li cov hlau tsis muaj steel, vim nws qhov chaw du, nws nyuaj rau siv roj. Nws kuj yog ib qho ua rau cov xim muaj teeb meem adhesion hauv dej plating lossis UV txheej txheej txheem. Yuav ua li cas los daws qhov teeb meem ntawm cov xim zaj duab xis adhesion nyob rau hauv cov txheej txheem tshuaj tsuag painting tau dhau los ua ib qho teeb meem loj nyob rau hauv kev lag luam painting, tab sis raws li cov lus hais mus: muaj ib txwm muaj ntau txoj kev daws teeb meem. Tseeb tiag, lub luag haujlwm ntawm tus neeg saib xyuas kev kho adhesion tuaj yeem yog tus neeg saib xyuas tshwj xeeb uas tuaj yeem txhim kho qhov adhesion ntawm cov xim zaj duab xis thiab substrate. Txoj kev txau yog siv los pleev xim rau saum npoo ntawm cov khoom thiab tom qab ntawd tshuaj tsuag xim. Muaj cov kev sib raug zoo rau cov khoom sib txawv. Los ntawm kev sib cuam tshuam los yog kev sib txuas ntawm cov khoom siv sib txuas, cov khoom siv tshuaj lom neeg, thiab lwm yam, kev ua haujlwm adhesion tau zoo tuaj. Nws kuj tseem nrov thiab tau txais hauv kev lag luam txheej. Pom zoo tshuaj rau kev txhim kho zaj duab xis adhesion.
