Kev Sib Piv ntawm Lub Sijhawm Qhuav thiab Cov Yam Ntxwv Hardness
Kev sib piv ntawm lub sijhawm ziab thiab cov yam ntxwv ntawm cov xim pleev xim acrylic sib txawv:
- Txoj kev ziab
Cov xim acrylic ib feem qhuav los ntawm kev ua kom cov kuab tshuaj yaj thiab ziab lub cev
Xim pleev xim acrylic polyurethane ob yam khoom yog kev sib xyaw ua ke ntawm cov resin thiab cov neeg sawv cev kho uas hla kev sib txuas tshuaj lom neeg.
- Lub sijhawm qhuav ntawm qhov chaw
Xim acrylic ib feem siv sijhawm 15-30 feeb
Xim pleev acrylic polyurethane ob yam khoom siv sijhawm li 1–4 teev (nyob ntawm qhov chaw ib puag ncig)
- Lub sijhawm qhuav tob
Cov xim acrylic ib feem siv sijhawm 2–4 teev
Xim acrylic polyurethane ob yam khoom siv sijhawm li 24 teev
- Xim zaj duab xis hardness
Xim acrylic ib feem yog nruab nrab, yooj yim siv
Xim pleev xim acrylic polyurethane ob txheej yog siab dua, nrog kev tiv taus huab cua zoo dua
- Txawm tias kev sib xyaw ua ke puas xav tau
Xim acrylic ib feem tsis tas yuav sib tov, npaj siv tau raws li nws yog
Cov xim pleev acrylic polyurethane ob yam yuav tsum tau sib tov cov khoom A/B kom sib npaug.
Lo lus "ua kom tawv" txhais tau hais tias thaum twg daim xim pleev xim muaj zog txaus los tiv taus qhov khawb me me thiab kev siv li niaj zaus. Kev ua kom tawv tag yuav siv sijhawm ob peb hnub lossis ntau dua ib lub lim tiam.
Cov yam tseem ceeb uas cuam tshuam rau kev ziab thiab tawv
Kub: Qhov kub siab dua, cov kuab tshuaj yuav ua pa sai dua, thiab lub sijhawm ziab luv dua; qis dua 5 ℃, kev ziab ib txwm yuav ua tsis tau.
Av noo: Thaum cov av noo ntau tshaj 85%, nws yuav ua rau qeeb qeeb ntawm qhov ziab.
Qhov tuab ntawm txheej: Yog tias siv txheej tuab dhau, qhov saum npoo yuav qhuav thaum txheej sab hauv tseem ntub, ua rau qhov tawv thiab lo rau.
Cov huab cua zoo: Kev ua pa zoo pab ua kom cov tshuaj yaj sai dua thiab ua kom qhuav zoo dua.
Cov xim pleev acrylic enamel yuav qhuav thiab tawv raws li qhov xwm txheej ib txwm muaj, uas yog lub hauv paus rau nws ua haujlwm tiv thaiv thiab kho kom zoo nkauj. Kev xaiv hom xim kom haum (ib feem/ob feem), tswj cov yam ntxwv ib puag ncig, thiab ua raws li cov lus qhia ntawm kev tsim kho yog qhov tseem ceeb kom ntseeg tau tias cov xim pleev zoo raws li cov qauv.
