Tsib yam ntawm cov yas txau ntawm cov txheej txheem hardboard yog raws li hauv qab no:
1. Annealing: Annealing yog cov txheej txheem ntawm kev tshem tawm cov kev ntxhov siab thaum lub sij hawm molding ntawm cov khoom yas. Annealing yog kom tsis txhob muaj teeb meem tawg ntawm qhov kev ntxhov siab tom qab pleev xim. Txoj kev kho annealing muaj cua sov cov yas molded qhov chaw hauv qab lub tshav kub deformation kub thiab tuav lawv li ob teev kom tshem tawm kev ntxhov siab.
2. Roj tshem tawm: Qhov saum npoo ntawm cov khoom yas feem ntau yog npog nrog roj, hws, thiab tso tawm tus neeg sawv cev, uas yuav ua rau cov txheej txheej adhesion tsis zoo thiab ua rau tawg, tawg, thiab tev. Degreasing yuav tsum tau ua ua ntej pleev xim. Cov khoom yas feem ntau yog ntxuav nrog roj av lossis cawv, thiab tom qab ntawd tshuaj degreased. Tom qab cov tshuaj degreasing, qhov chaw ntawm lub workpiece yuav tsum tau muab ntxuav kom huv si nrog cov lye seem thiab thaum kawg ntxuav nrog dej ntshiab thiab qhuav los yog qhuav.
3. Ntxiv rau qhov hluav taws xob thiab hmoov av: Cov khoom siv yas yog cov insulators, qhov chaw tiv thaiv feem ntau nyob ib puag ncig 1013Ω, yooj yim los tsim hluav taws xob zoo li qub. Tom qab raug them, nws yog ib qho yooj yim rau adsorb cov plua plav zoo hauv huab cua thiab txuas rau saum npoo. Vim yog electrostatic adsorption ntawm plua plav nrog rau txoj kev tshuab dav dav kom tshem tawm nyuaj heev, kev siv cov cua kub siab ionized nyob rau tib lub sijhawm kom tshem tawm hluav taws xob thiab plua plav yog qhov zoo dua.
4. Txau: yas txheej thickness ntawm 15 ~ 20μm, feem ntau 2 ~ 3 txau kom tiav. Txau tom qab 15 feeb ntawm ziab, tom qab ntawd los ntawm lwm yam tshuaj tsuag. Qhov saum npoo uas yuav tsum tau ci yuav tsum tau txau nrog cov xim pob tshab. Cov coated qhov chaw tsis cuam tshuam cov nplaim retardant kev ua tau zoo.
5. Qhuav: Tom qab txheej, nws tuaj yeem qhuav ntawm chav tsev kub lossis ci ntawm 60 degree rau 30min. Cov txheej txheem txheej txheej yas zoo tuaj yeem txhim kho cov khoom lag luam zoo thiab peb lub tuam txhab tau koom nrog cov txheej txheem yas txau rau ntau xyoo thiab muaj cov txheej txheem ua tiav.
Cov ntsiab lus saum toj no yog cov txheej txheem tshuaj tsuag yas hauv cov txheej txheem ntawm tes, Kuv vam tias yuav ua kom koj nkag siab tob txog cov txheej txheem ntawm tes. Yog hais tias koj xav paub ntau ntxiv txog lub teeb tes board ua, txais tos rautiv tauj peb, peb yuav zoo siab los pab koj.
