Iav khov khoom siv tau txhawb kev loj hlob ntawm kev lag luam chemical. Nws yog tsim siv cov txheej txheem hluav taws xob kub tshwj xeeb. Nws yog ib qho tshuaj pleev kom zoo rau cov ntaub ntawv carbonaceous thiab cov khoom siv tseem ceeb rau kev tiv thaiv oxidation. Nws yog tsuas yog siv los ua cov siv lead ua primer thaum tsim rooj tog. Nws kuj tseem siv dav raws li cov xim hauv qab rau kev kho kom zoo nkauj.
1. Cov iav da dej ua rau cov khoom siv tsuas yog siv los ua cov siv lead ua xim tshiab hauv kev tsim cov rooj tog hauv txheej. Nws kuj tseem siv dav siv los ua ob lub hom phiaj rau kev kho kom zoo nkauj. Pom tias ntxiv qhov sib piv 5% -10%
2. Hauv cov rooj tog zaum xim tiav, nws cov pob tshab, thixotropy, hardness, thiab abrasion kuj zoo heev. Tus nqi pom zoo kom ntxiv yog 3-7%, thiab cov xim tha xim yog 5-10%.
3. Tsim nyog rau cov xim yas thiab xim hlau, cov tshuaj pom zoo yog 10-15%.
Cov iav frosted cov khoom tuaj yeem txo qhov hluav taws kub tsis kam rau hauv tus neeg saib xyuas kev cog lus, txhawb kev tsim lub khob lub cev, thiab zoo heev txhim kho lub zog ntawm kev ua kom zoo. Ua kom muaj kev nyeem ntxiv thiab ntub ntawm phau ntawv txhawm rau ua kom cov ntawv ci kom zoo nkauj faib ib ncig ntawm cov xaum abrasive. Txo qhov shrinkage ntawm tus neeg sawv cev khi thiab txhim kho lub zog thiab kev ua kom muaj zog ntawm tus neeg sawv cev khi nws tus kheej.
