Vijtsam luam ntawv xim yog qhov tseem ceeb xim hauv cov txheej txheem luam ntawv, tsis muaj tus number case ntxiv cov xim rau cov khoom, luam ntawv yuav poob nws qhov tseem ceeb. Yog li, koj puas paub dab tsi yog cov khoom xyaw hauv tshuaj ntsuam luam ntawv number case?
Cov xim muaj xim muab rau ntau lub ntiaj teb kev zoo nkauj, thiab cov xim no kuj tseem tuaj yeem siv tshuab luam ntawv los kos cov qauv zoo nkauj. Dab tsi yog cov khoom xyaw hauv tshuaj ntsuam luam ntawv number case uas tuaj yeem ua rau cov xim pleev xim rau lub thawb duab?
1. Daim ntawv: nws yog hom kua nplaum, uas tuaj yeem lo cov xim ntawm lub zom zaws, ua si ua lub luag haujlwm zoo nkauj ua kom pom tseeb. Los ntawm phau ntawv qhia, peb kuj tuaj yeem pom cov viscosity, kom qhuav thiab nrawm ntawm kev ua haujlwm ntawm tus number case. Lub binder yuav tsum yog qhov zoo. Qhov tseem ceeb ntawm cov binder yog cov roj zaub los yog cov roj ntxhia, thiab cov roj ua hnav kuj yog qhov tseem ceeb.

2. Xim Xim: cov xim txau ua tau yog ib hom xim zoo nkauj, uas nyuaj rau yaj hauv dej thiab tsis txuam nrog phau ntawv tiv thaiv. Feem ntau, nws yuav raug muab tshem tawm, nrog xim zoo nkauj, zoo txaus thiab pob tshab. Lwm cov xim zas yog qhov sib txawv, siab solubility, tab sis kuj muaj nws qhov zoo, tab sis tuaj yeem siv rau hauv luam ntawv number case.
3. Cov koom tes: los ntawm cov ntsiab lus lus nkag siab kom nkag siab, qhov tseeb, yog los pab number case zoo dua los ua lub luag haujlwm. Cov npo luam ntawv tuaj yeem ua rau kev ua haujlwm ntawm tus number case zoo dua. Piv txwv li, cov voos yas ua kom cov yas ntawm cov number case, txhim kho qhov muag muag ntawm tus number case; Diluent ua cov mem kua thinner, yog li ntawd tus number case muaj qhov ua tau zoo dua; Tshem cov nplaum tuaj yeem ua rau lub viscosity ntawm tus number case tsawg dua; Drier tseem hu ua desiccant, number case tuaj yeem ua kom qhuav.
Qhov zoo ntawm npo luam ntawv number case yog ncaj qha ntsig txog qhov zoo ntawm cov ntawv luam tawm nws tus kheej. Yog li ntawd, peb yuav tsum xyuam xim rau qhov no. Xaiv tus number case kom yog tus yuam sij rau qhov zoo ntawm kev luam ntawv.
