PVDF xim-coated txhuas kauj yog ib hom coated txhuas uas yog dav siv nyob rau hauv lub tsev facades thiab ru tsev systems vim nws durability, huab cua tsis kam thiab zoo nkauj thov. Cov txheej txheem xim txheej muaj ob peb kauj ruam, qhov tseem ceeb tshaj plaws ntawm cov menyuam txheej. Hauv tsab xov xwm no, peb yuav tshawb xyuas cov kauj ruam uas cuam tshuam rau cov txheej txheem txheej txheem ntawm PVDF xim-coated aluminium coil.
Kauj Ruam 1: Kev npaj deg
Thawj kauj ruam hauv cov txheej txheem rau cov menyuam txheej yog kev npaj nto. Aluminium substrate yog huv si huv si thiab degreased kom tshem tawm tej impurities los yog tej yam kab mob uas yuav cuam tshuam rau adhesion ntawm cov khoom txheej. Tom qab ntawd, qhov saum npoo yog kho nrog cov tshuaj etching los txhim kho nws qhov roughness thiab txhim kho lub zog sib txuas ntawm cov txheej.
Kauj ruam 2: Priming
Qhov thib ob theem yog priming, uas yuav tsum tau thov ib tug primer rau saum npoo ntawm aluminium substrate. Lub primer ua hauj lwm pab raws li ib tug basecoat los txhim kho lub adhesion ntawm topcoat thiab muab corrosion kuj rau cov txhuas. Cov primer feem ntau yog cov kuab tshuaj los yog cov khoom siv dej uas muaj cov resins, pigments, thiab additives.
Kauj Ruam 3: Sab saum toj txheej
Cov kauj ruam thib peb yog txheej txheej saum toj kawg nkaus, uas suav nrog kev siv cov khoom siv PVDF txheej siv lub tshuab rau cov menyuam txheej. PVDF txheej yog ib qho kev ua tau zoo fluorocarbon polymer uas paub txog nws cov huab cua zoo heev, ua haujlwm ntev, thiab xim tuav. Cov txheej txheej zoo muab cov txhuas ua kom du, glossy tiav uas tiv taus fading, chalking, thiab tawg.
Kauj Ruam 4: Kho
Cov kauj ruam thib plaub thiab zaum kawg yog kho, uas suav nrog kev ci cov coated aluminium coil nyob rau hauv qhov cub kub kub kom hla cov txheej txheej thiab xyuas kom nws ua haujlwm zoo. Lub sijhawm kho thiab kub hloov pauv nyob ntawm cov khoom siv txheej, tab sis feem ntau, nws yuav siv li ntawm 10-15 feeb ntawm qhov kub ntawm 200-220 degree .
Hauv kev xaus, cov kauj ruam uas koom nrog hauv cov txheej txheem txheej txheej txheej txheej ntawm PVDF xim-coated aluminium coil yog kev npaj nto, priming, txheej sab saum toj, thiab kho. Txhua kauj ruam yog qhov tseem ceeb kom ua tiav qhov xav tau txheej txheej thiab zoo li. Los ntawm kev ua raws li cov kauj ruam no, cov tuam ntxhab tuaj yeem tsim cov xim zoo-coated aluminium coils uas ua tau raws li cov qauv kev lag luam nruj tshaj plaws thiab cov neeg siv khoom xav tau.
