Dab tsi yog Acrylic Powder Coatings
Acrylic hmoov txheej hmoov muaj cov khoom zoo nkauj zoo nkauj, huab cua tsis kam, thiab muaj kuab paug tsis kam, thiab muaj qhov tawv tawv siab. Zoo saj zawg zog. Tab sis tus nqi yog siab thiab corrosion kuj tsis zoo. Yog li ntawd, European lub teb chaws generally siv ntshiab polyester hmoov (carboxyl-muaj resin, kho nrog TGIC); (hydroxyl-muaj polyester cob yog kho nrog isocyanate) raws li huab cua-resistant hmoov txheej.
Muaj pes tsawg leeg
Acrylic hmoov txheej yog tsim los ntawm acrylic resins, pigments thiab fillers, additives thiab curing agents.
hom
Vim muaj cov pab pawg ua haujlwm sib txawv uas muaj nyob hauv cov qauv molecular, acrylic resins muaj cov hauv qab no:
1. Acrylic resin muaj glycidyl ether functional pawg.
2. Acrylic resin muaj carboxyl functional pawg.
3. Acrylic resin muaj hydroxyl functional pawg.
Kev Kho Mob
Vim yog cov qauv sib txawv thiab cov pab pawg ua haujlwm muaj nyob rau hauv acrylic resins, xaiv cov tshuaj tua kab mob thiab cov txheej txheem kho kuj sib txawv. Tom qab hla kev sib txuas, lub cev thiab tshuaj lom neeg kuj sib txawv.
Cov txheej txheem kho ntawm acrylic hmoov txheej yog:
Kub kub: 180 ℃ ~ 200 ℃;
Lub sijhawm kho: 15min ~ 20min;
Daim ntawv thov txheej txheem ntawm thermosetting hmoov txheej yuav siv tau rau acrylic hmoov txheej.
Cov Txheej Txheem Ua
Muaj plaub txoj kev tsim khoom rau acrylic hmoov txheej:
Ib qho yog txoj kev evaporation.
Qhov thib ob yog txoj kev tshuaj tsuag kom qhuav.
Qhov thib peb yog txoj kev ntub dej.
Thaum kawg, nws yog tib yam li cov txheej txheem ntau lawm ntawm epoxy hmoov txheej.
Txoj kev tsim plaub feem ntau yog siv.
Cov txheej txheem yog raws li hauv qab no:
Sib tov → extrusion → crushing → sieving → ntim
