Daim ntawv qhia ceev rau cov txheej txheem Varnishing rau cov ntawv lo!
Varnishing yog hais txog kev siv cov txheej tsis muaj xim, pob tshab kua roj vanish rau ntawm daim ntawv lo. Lub hom phiaj yog txhawm rau ua kom lub ntsej muag ci ntawm cov khoom luam tawm, nrog rau kev tiv thaiv nws los ntawm stains, noo noo, thiab kev puas tsuaj rau cov duab thiab cov ntawv. Feem ntau, cov kua roj vanish tuaj yeem muab faib ua cov kua roj vanish, cov kua roj vanish, thiab cov kua roj vanish rov qab. Hauv tsab xov xwm no, kuv yuav piav qhia peb cov txheej txheem varnishing no thiab nkag mus rau hauv lawv cov yam ntxwv thiab cov ntsiab lus tseem ceeb rau kev siv.
Cov kua roj vanish
Cov yam ntxwv ntawm Full Varnish
Cov kua roj vanish tag nrho, tseem hu ua cov kua roj vanish tag nrho, suav nrog kev siv cov kua roj vanish uas tsis muaj xim pob tshab thoob plaws tag nrho daim ntawv lo. Tom qab leveling, ziab, nias, thiab kho, nws tsim ib txheej nyias, zoo ib yam, glossy txheej uas smooths daim ntawv lo saum npoo thiab txhim kho cov ntawv luam tawm.
Nws yog tsim nyog sau cia tias cov kua roj vanish yog txawv ntawm lamination. Lamination yog hais txog kev siv cov yas yas pob tshab, 0.012-0.020mm tuab, mus rau daim ntawv lo tom qab luam ntawv siv cov cua sov los yog siab, yog li daim ntawv lo thiab zaj duab xis sib xyaw ua ke. Raws li pom nyob rau hauv daim duab 1 (sab laug) yog ua ntej-coated zaj duab xis cov ntaub ntawv uas yuav tsum tau tshav kub rau lamination, thiab daim duab 1 (txoj cai) qhia zaj duab xis cov ntaub ntawv uas yuav tsum tau siab rau lamination.
