Hav nyob ntawd, cov phooj ywg txheej enthusiasts! Raws li tus neeg muag khoom ntawm cov neeg ua haujlwm qib, kuv feem ntau tau nug yog tias muaj cov neeg ua haujlwm qib uas tsim nyog rau cov txheej txheem siab -. Zoo, cov lus teb luv luv yog yog, tab sis cia peb nkag mus tob rau hauv cov ncauj lus no.
Cov txheej txheem siab - tau txais txiaj ntsig ntau hauv xyoo tas los no. Lawv muab ntau qhov zoo dua li cov txheej txheem ib txwm muaj. Rau qhov pib, lawv muaj qis dua volatile organic compound (VOC) emissions. Qhov no yog qhov loj heev, tshwj xeeb tshaj yog nrog kev nce ib puag ncig kev cai thoob ntiaj teb. Tib neeg tau paub ntau ntxiv txog qhov cuam tshuam ntawm cov tshuaj lom neeg rau ib puag ncig, thiab siab - cov txheej txheej yog ib kauj ruam ntawm txoj kev.
Tab sis siab - cov txheej txheej tseem tuaj nrog lawv tus kheej cov teeb meem nyuaj. Ib qho ntawm cov teeb meem tseem ceeb yog ua kom tiav qhov du thiab txawm tias tiav. Txij li cov coatings no muaj cov ntsiab lus ntau dua, lawv yuav muaj kuab ntau dua. Qhov no nce viscosity tuaj yeem ua rau muaj teeb meem xws li txiv kab ntxwv tev nyhuv, txhuam cov cim, lossis tsis sib xws. Qhov ntawd yog qhov uas cov neeg ua haujlwm leveling tuaj.
Leveling agents yog cov additives uas pab txhim kho qhov ntws thiab qib ntawm cov txheej txheem. Lawv ua hauj lwm los ntawm kev txo qhov nro ntawm lub txheej, cia nws kis tau tusyees tshaj lub substrate. Hauv siab - cov txheej txheej, qhov no yog qhov tseem ceeb rau kev ua tiav qib siab - zoo.
Muaj ntau hom sib txawv ntawm cov neeg ua haujlwm leveling muaj nyob hauv khw. Qee qhov yog raws li silicone, thaum lwm tus yog acrylic lossis fluorocarbon - raws. Txhua hom muaj nws tus kheej cov khoom thiab qhov zoo.
Silicone - raws li tus neeg ua haujlwm qib yog nrov heev. Lawv muaj kev ua haujlwm zoo heev thiab tuaj yeem muab siab - gloss tiav. Lawv kuj muaj cov nplaum nplaum zoo thiab tiv thaiv - thaiv cov khoom, uas txhais tau hais tias cov chaw coated tsis tshua muaj peev xwm los ua ke. Txawm li cas los xij, qee zaum lawv tuaj yeem ua teeb meem nrog kev rov ua dua yog tias tsis siv kom raug.
Acrylic - raws li tus neeg sawv cev qib yog lwm txoj kev xaiv. Lawv tau sib xws nrog ntau yam txheej txheej txheej thiab feem ntau yog ib puag ncig zoo. Lawv muaj peev xwm muab tau zoo leveling thiab ntws zog, thiab lawv kuj tsis tshua muaj feem yuav ua rau defects nto.
Fluorocarbon - raws li leveling agents paub txog lawv cov khoom zoo heev. Lawv tuaj yeem muab cov dej zoo thiab cov roj tawm, nrog rau cov khoom tiv thaiv - graffiti. Tab sis lawv feem ntau kim dua li lwm hom.
Thaum xaiv tus neeg sawv cev rau qib siab - cov txheej txheej, muaj ntau yam los xav txog. Ua ntej ntawm tag nrho cov, koj yuav tsum xav txog qhov compatibility nrog txheej txheej. Tus neeg sawv cev theem yuav tsum muaj peev xwm yaj lossis tawg tau zoo hauv cov txheej txheem yam tsis ua rau muaj kev sib cais theem lossis lwm yam teeb meem.
Koj kuj yuav tsum xav txog txoj kev thov. Cov kev siv sib txawv, xws li tshuaj tsuag, txhuam hniav, lossis dov, yuav xav tau ntau hom kev sib txawv. Piv txwv li, kev siv tshuaj tsuag tuaj yeem xav tau tus neeg sawv cev qib uas tuaj yeem txo qhov nro nrawm kom tiv thaiv cov txiv kab ntxwv tev.
Lwm qhov tseem ceeb yog qhov xav tau tiav. Yog tias koj xav tau qhov siab - gloss tiav, koj yuav xav tau tus neeg sawv cev sib txawv dua li yog tias koj mus rau matte tiav.
Ntawm peb lub tuam txhab, peb muaj ntau yam ntawm cov neeg ua haujlwm leveling haum rau siab - cov khoom coatings. Peb tau ua ntau yam kev tshawb fawb thiab kev tsim kho kom ntseeg tau tias peb cov khoom tuaj yeem ua tau raws li cov kev xav tau tshwj xeeb ntawm cov neeg siv khoom sib txawv.

Ib tug ntawm peb cov neeg muas zaub, ib tug me me - scale pleev xim chaw tsim tshuaj paus, tau muaj teeb meem nrog rau theem ntawm lawv siab - khoom automotive txheej. Lawv tau txais ntau cov txiv kab ntxwv tev nyhuv, uas cuam tshuam rau lawv cov khoom zoo. Tom qab sim ntau tus neeg sawv cev sib txawv ntawm kev ua lag luam, lawv tuaj rau peb. Peb pom zoo ib qho ntawm peb cov silicone - raws li tus neeg ua haujlwm qib, thiab tom qab qee qhov kev hloov kho rau kev tsim, lawv muaj peev xwm ua tiav qhov du thiab txawm tiav. Lawv cov neeg siv khoom tau zoo siab tiag tiag nrog kev txhim kho zoo ntawm cov txheej txheem, thiab lawv tau siv peb cov khoom txij thaum ntawd los.
Tam sim no, yog tias koj xav paub ntau ntxiv txog kev ua haujlwm ntawm peb cov neeg ua haujlwm theem, koj tuaj yeem tshawb xyuas qhov txuas no:4-testsdfgsdfg ua.
