Ua ntej luam ntawv ntim muag muag, thawj zaug nrhiav kom paub cov hom thiab cov hau kev ntawm kev siv dej-ua kua mem ntxiv rau!
Peb yog lub tuam txhab luam ntawv loj hauv Shenzhen Tuam Tshoj. Peb muab tag nrho cov phau ntawv tshaj tawm, hardcover phau ntawv luam ntawv, ntawv thawm phau ntawv luam ntawv, phau ntawv phau ntawv hardcover, sprial phau ntawv luam ntawv, eeb stiching phau ntawv luam ntawv, phau ntawv luam ntawv, ntim ntawv thawv, daim ntawv qhia hnub nyoog, txhua yam ntawm PVC, cov khoom lag luam ntawv, sau ntawv, Cov menyuam yaus phau ntawv, ntawv nplaum, txhua yam hom ntawm cov ntawv tshwj xeeb xim luam ntawv cov khoom lag luam, game cardand so.

Cov khoom siv uas nquag siv rau hauv cov dej-raws li kev ua tau yog: pH stabilizers, defoamers, cov khoom siv qeeb-ziab, cov neeg ua haujlwm sai-nrawm, thiab cov zoo li. Cov haujlwm yog dab tsi, thaum twg lawv ntxiv, thiab yog dab tsi siv?
1, PH stabilizer. Lub pH stabilizer tuaj yeem ntxiv cov tshuaj ammonia thiab dej hloov tawm los ntawm tus number case hloov chaw thaum lub sijhawm luam ntawv, uas yuav pab kom cov viscosity ntawm tus number case nyob ruaj khov thiab ua kom cov luam ntawv zoo. Ua raws rau cov substrate, pH stabilizers tau muab faib ua hom qub thiab nyias zaj duab xis. Thaum luam ntawv cov xov hluav taws xob zoo, siv cov khoom siv pH stabilizer. Cov pH stabilizer feem ntau yog siv los ntxiv 1% rau 2% ntawm tag nrho cov kua dej nyob hauv txhua 30-40 feeb kom do tusyees, lossis ntxiv cov stabilizer rau cov twj tso kua mis circulating.
2, defoamer. Feem ntau, tus nqi tsim nyog ntawm tus neeg sawv cev tiv thaiv kab mob yog ntxiv rau tus number case ua ntej pib luam ntawv kom tiv thaiv tus number case los ua npuas ncauj, thiab tus nqi tsim nyog ntawm tus neeg sawv cev tiv thaiv kab mob yuav raug ntxiv yog tsim nyog thaum luam ntawv. Tus nqi ntawm cov tshuaj tua kab mob tus neeg sawv cev tsis tshaj 0.5% mus rau 1% ntawm tag nrho cov kua mem kua ib zaug.
3, ceev kom qhuav, tus neeg sawv cev qeeb. Tus neeg sawv cev ceev-nrawm thiab qeeb-txias tuaj yeem ntxiv rau tus number case raws li cov ntawv luam tawm ceev ntawm lub tshuab luam ntawv, thiab lub tshuab ua kom qhuav nrawm nrawm tuaj yeem hloov tau kom tau txais txiaj ntsig luam ntawv. Tus nqi yog los ntawm 1% txog 2% ntawm tag nrho cov kua mem.
4, thim tawm ntawm cov neeg sawv cev. Hauv qab ntawm qhov pH uas tsis tu ncua thiab viscosity, qhov sib ntxiv ntawm tus neeg sawv cev tiv thaiv tuaj yeem txo qhov xim xim ntawm tus number case. Tus nqi yuav tsum tau txiav txim siab nyob ntawm ib ntu zuj zus.
5, thinner. Qhov sib ntxiv ntawm qhov tsis haum rau tus number case txo qhov viscosity ntawm cov dej noo-raws li tus cwj mem tsis cuam tshuam rau pH. Tus nqi yuav tsum tsis txhob ntau dua 5% ntawm tag nrho cov kua mem.
6, txhim kho. Tus neeg sawv cev tuaj yeem tuaj yeem txhim kho qhov kev nplaum ntawm cov luam ntawv lossis cov kua roj vanish rau cov khoom siv luam ntawv, thiab tus nqi feem ntau yog li ntawm 1% mus rau 2% ntawm tus nqi ntawm tag nrho cov number case.
7, tshem tawm cov kab mob zoo li qub. Tus neeg sawv cev antistatic tuaj yeem tiv thaiv kom tsis txhob muaj hluav taws xob zoo li qub ntawm lub tshuab luam ntawv, thiab tus nqi ntawd feem ntau yog li 0.5% mus rau 1% ntawm tag nrho cov number case.
