Cov hmoov txheej daim ntawv thov tus nqi yog ncaj qha ntsig txog cov ntsiab lus resin, them nyiaj ntxiv, muab tub lim, thiab hmoov particle loj faib.
Ua kom cov ntsiab lus resin thiab txo cov ntsiab lus muab tub lim, thiab xaiv cov resins nrog cov khoom siv zoo, xws li epoxy (uas yooj yim dua rau cov hmoov), thaum qee cov tuam txhab tsis siv cov hmoov rau polyester (uas nyuaj dua rau siv cov hmoov, vim epoxy thiab polyester yog hauv av rau hauv cov hmoov tshuaj tsuag sib cais), ua rau muaj kev sib txhuam zoo dua nrog rab phom sib sib zog nqus piv rau rab phom electrostatic coated.
Ntxiv qhov tsim nyog tus nqi ntawm cov khoom siv hluav taws xob ntxiv rau cov qauv tso cai rau cov hmoov hmoov nqa tau tus nqi ntau dua. Ib qho hluav taws xob muaj zog muaj nyob rau hauv thaj tsam ntawm qhov siab -voltage electrostatic spray gun thiab workpiece, thiab huab cua yog ionized, tsim billions ntawm ions. Thaum cov hmoov nplej uas tau them dhau los ntawm thaj chaw no, lawv tau polarized, ntes ntau cov ions tsis zoo thiab tau txais tus nqi ntau dua. Hauv cov cheeb tsam xws li grooves thiab cov fab tuag, qhov twg Faraday effect ua rau cov kab hluav taws xob tsis muaj zog, cov hmoov nplej ntau dua tuaj yeem ncav cuag qhov chaw ua haujlwm los ntawm lawv tus kheej lub zog, yog li txhim kho cov hmoov hmoov hauv cov cheeb tsam no.
Lub fineness thiab dispersion ntawm fillers yog ze ze rau cov hmoov thov. Cov nag lossis daus yog siab dua li ntawm ultrafine hnyav barium sulfate, thiab zoo dua li ntawm calcium carbonate.
Tswj cov hmoov particle loj faib yog qhov tseem ceeb; qhov nqaim qhov zoo. Tsim nyog tswj cov hmoov particle loj yog qhov nyuaj. Hauv peb qhov kev tsim khoom tiag tiag, peb tsuas tuaj yeem kho qhov nrawm ntawm lub ntsiab thiab pabcuam mills hauv ACM. Cov hmoov particle loj ntawm 40-50 μm yog suav tias tsim nyog, thiab qhov nqaim ntawm kev faib tawm, qhov zoo dua.
