Kev Taw Qhia:
Kev txheej txheej rau cov menyuam tau dhau los ua txoj hauv kev nyiam tshaj plaws rau kev siv cov txheej txheej rau ntawm cov hlau txhuas vim nws qhov ua tau zoo thiab ua tau zoo. Nrog rau qhov kev thov ntau ntxiv rau cov khoom lag luam txhuas zoo thiab ruaj khov, kev txheej txheej rau cov menyuam tau dhau los ua ib qho txheej txheem tseem ceeb hauv kev lag luam txhuas. Txawm li cas los xij, txhawm rau kom ua tiav cov txiaj ntsig xav tau, nws yog ib qho tseem ceeb kom nkag siab txog cov kev cai ua haujlwm tshwj xeeb rau kev txheej txheej rau cov menyuam. Hauv cov blog no, peb yuav nkag mus rau hauv cov kev cai ua haujlwm tseem ceeb uas cov txheej txheej rau cov menyuam yuav tsum ua tiav, tsom mus rau qhov viscosity thiab leveling zog, kho sai, kho kom zoo nkauj, thiab tiv taus huab cua.
1. Qhov viscosity tsim nyog thiab cov khoom zoo leveling:
Cov txheej txheem txheej txheej rau cov menyuam muaj xws li kev pub siv txoj siv sia sai, txheej txheej rau cov menyuam, ci kub siab, thiab txias sai. Yuav kom ntseeg tau tias cov khoom sib npaug zoo tshaj plaws, nws yog qhov tseem ceeb rau cov menyuam txheej kom siv cov xim txaus rau ntawm cov khoom siv txhuas. Yog li ntawd, cov txheej txheej rau cov menyuam yuav tsum muaj cov viscosity tsim nyog thiab cov khoom sib npaug zoo. Cov viscosity ntawm cov txheej yuav tsum tau ua tib zoo tsim kom yooj yim siv thaum tswj nws lub peev xwm los sib npaug ntawm qhov chaw txhuas. Kev ua tiav qhov sib npaug viscosity yog qhov tseem ceeb hauv kev tiv thaiv cov teeb meem xws li cov tuab txheej tsis sib npaug, cov kab txaij, thiab cov teebmeem ntawm cov tawv txiv kab ntxwv.
2. Kho sai:
Vim yog qhov ceev ceev ntawm cov kab tsim cov xim pleev xim rau cov menyuam, kev kho sai yog qhov tseem ceeb rau cov xim pleev xim rau cov menyuam. Vim tsis muaj kev txhawb nqa thiab qhov cub ci ntev tsawg, lub sijhawm rau cov xim kom kho tau raug txo qis heev. Cov xim siv rau hauv cov xim pleev xim rau cov menyuam yuav tsum tau tsim kom kho tau hauv lub sijhawm luv luv, zoo dua tsawg dua 60 vib nas this. Tsis tas li ntawd, cov txheej txheem kho yuav tsum ua kom cov xim qis dua qhov kub ntawm lub kauj ntawm 260°C kom tiv thaiv cov khoom los ntawm kev hloov pauv lossis lwm yam kev tsis zoo. Kev xaiv cov kuab tshuaj kom raug yog qhov tsim nyog kom ua tiav kev kho sai yam tsis muaj kev cuam tshuam rau kev ncaj ncees ntawm cov txheej, zam cov teeb meem xws li npuas, qhov, thiab qib tsis zoo.
3. Cov yam ntxwv zoo nkauj:
Ntxiv rau cov yam ntxwv ua haujlwm, cov txheej txheej roller coatings kuj yuav tsum ua tau raws li qhov yuav tsum tau ua kom zoo nkauj. Cov xim polyester feem ntau txaus rau kev ua tiav qhov zoo li xav tau nrog ib daim ntawv thov. Txawm li cas los xij, thaum siv cov txheej fluorocarbon, cov primer thiab topcoat yog qhov tsim nyog rau cov txiaj ntsig zoo nkauj. Cov primer yuav tsum muaj kev tiv thaiv corrosion zoo heev thiab lo rau ob qho tib si substrate thiab topcoat, thaum cov topcoat yuav tsum ua kom pom tseeb zoo zais lub zog thiab cov khoom dai kom zoo nkauj. Ib txheej ntawm primer ua raws li ib txheej ntawm topcoat tuaj yeem ua rau muaj qhov zoo nkauj uas ua tau raws li ob qho tib si aesthetic thiab kev ua haujlwm xav tau.
4. Kev tiv thaiv huab cua:
Cov txheej txheej txheej rau cov menyuam yuav tsum ua kom pom tias muaj kev tiv thaiv huab cua zoo heev, tshwj xeeb tshaj yog thaum siv rau cov khoom siv txhuas sab nraum zoov. PVDF fluorocarbon coatings feem ntau yog siv los muab kev ua tau zoo tiv thaiv cov yam xws li kev ruaj khov, nag acid, pa phem, xeb, cov xim sawv ntsug, thiab pwm. Nyob ntawm qhov chaw xav tau tshwj xeeb, ob, peb, lossis plaub txheej ntawm PVDF txheej tuaj yeem siv tau. Qhov no ua kom muaj kev tiv thaiv ntev thiab kev ua siab ntev tshaj plaws, uas tso cai rau cov txheej txhuas coated kom tiv taus txawm tias qhov xwm txheej ib puag ncig hnyav tshaj plaws.
Xaus lus:
Xaus lus, kev ua tiav qhov kev ua tau zoo tshaj plaws rau cov txhuas coils yuav tsum tau xav txog qhov viscosity thiab leveling ntawm cov txheej, kev kho sai, cov yam ntxwv zoo nkauj, thiab kev tiv thaiv huab cua. Los ntawm kev nkag siab thiab ua raws li cov kev cai ua tau zoo no, cov chaw tsim khoom tuaj yeem tsim cov khoom lag luam txhuas zoo uas ua tau raws li cov qauv xav tau ntawm ntau yam kev lag luam. Raws li qhov kev thov rau cov txhuas coils txhim khu kev qha thiab pom kev zoo nkauj txuas ntxiv mus, nws yog qhov tseem ceeb heev rau kev xaiv thiab siv cov txheej txheem roller uas tuaj yeem ua tiav cov kev cai ua tau zoo tseem ceeb no.
