Txheej txheej yog ib yam khoom siv ntau heev hauv peb lub neej lossis kev ua haujlwm, tab sis nrog kev txhim kho txuas ntxiv ntawm cov neeg siv khoom paub, txhua tus neeg muaj kev xav tau ntau dua rau kev xaiv cov txheej txheem. Hauv kev tsim khoom, polyurethane coatings tau dhau los ua ib qho kev xaiv tshiab rau txhua tus neeg uas muaj cov yam ntxwv zoo heev.Yog li dab tsi yog cov yam ntxwv ntawm cov txheej txheem polyurethane, thiab cov yam ntxwv ua haujlwm li cas hauv kev tsim khoom tam sim no?
Polyurethane txheejyam ntxwv:
1. Zoo heev hnav tsis kam
Xim yog ib yam khoom siv rau saum npoo ntawm ib yam khoom. Nws lub luag haujlwm tseem ceeb tuaj yeem muab faib ua ob qhov xwm txheej, ib qho yog kho kom zoo nkauj thiab lwm qhov yog kev tiv thaiv.Lub ntsiab ntawm kev hnav tsis kam yog los cuam tshuam cov yam ntxwv ntawm kev tiv thaiv polyurethane. Tom qab siv cov txheej txheem polyurethane sib raug, ib zaj duab xis tiv thaiv yog tsim rau ntawm qhov chaw ntawm cov khoom, txawm tias nyob rau hauv cov txheej txheem ntawm kev thauj mus los los yog siv los txo cov kev sib txhuam ntawm sab nraud quab yuam ntawm cov khoom nws tus kheej, ntau yam cim generated, thiab lwm yam.
2. Cov tshuaj lom neeg thiab roj ua haujlwm zoo heev
Cov tshuaj lom neeg thiab cov roj stains yog cov khoom corrosive uas muaj feem cuam tshuam nrog thaum siv cov khoom siv, thiab cov khoom no muaj kev cuam tshuam zoo rau cov qauv ntawm cov khoom nws tus kheej los yog kev zoo nkauj ntawm qhov chaw.Thaum siv polyurethane coatings, lawv tuaj yeem ua lub luag haujlwm zoo hauv tshuaj lom neeg thiab roj ua haujlwm, tswj kev huv ntawm cov khoom nto thiab qhov sib thooj zoo li kev ncaj ncees.
3. Muaj zog adhesion
Lub luag haujlwm ntawm coatings yog tsim ib zaj duab xis rau ntawm qhov chaw ntawm cov khoom. Txawm hais tias nws yog kev tiv thaiv los yog kho kom zoo nkauj, nws yuav tsum tau khi rau cov khoom. Polyurethane coatings muaj qhov adhesion siab heev thiab tuaj yeem ua kom nruj dua rau cov khoom kom tau raws li qhov yuav tsum tau ua.
4. Tsawg kub curing kev ua tau zoo
Nyob rau hauv cov ntaub ntawv polymer, qhov curing kub ntau ntawm polyurethane yog dav heev, thiab nws tuaj yeem kho tau ntawm qhov kub thiab txias, uas ua rau nws muaj peev xwm tiv thaiv cov khoom hauv ib puag ncig tshwj xeeb.Tam sim no, nyob rau hauv cov txheej txheem ntawm kev siv, lwm yam khoom. tuaj yeem muab ntxiv los ua kom zoo nkauj ntawm cov khoom thiab ua si zoo nkauj zoo nkauj.
5. Ib puag ncig tus phooj ywg thiab tsis muaj tshuaj lom
Vim li cas polyurethane coatings thiaj li nrov, qhov tseeb, nws yog ib qho tseem ceeb heev uas lawv ua tau raws li cov yam ntxwv ntawm kev tiv thaiv ib puag ncig. Tsis muaj kev tso tawm cov tshuaj lom thaum siv, uas muaj kev nyab xeeb rau cov neeg siv.Thiab rau tag nrho ib puag ncig, nws kuj yog ib puag ncig zoo.
