Cov tsheb thauj khoom hauv lub cev yog cov khoom tseem ceeb ntawm kev thauj mus txias thiab, hauv kev siv tom qab, txiav txim siab lub neej thiab kev pabcuam lub neej. Yog li ntawd, thaum lub sijhawm ua kev ua noj txhua hnub thiab kev tsim khoom, muaj ntau cov ntsiab lus ua uas yuav tsum tau saib xyuas tshwj xeeb.
1. Cov khoom siv raw ua tau zoo thiab ua feem: nruj tswj cov khoom siv raw khoom xws li Isocyanate, cov neeg sawv cev, thiab catalyst. Rau cov ntawv sau ua tiav polyurethane, xyuam xim rau cov yam ntxwv xws li ntom thiab lub zog.
2. Kev ntsuas kub: raw khoom kub thiab huab cua kub, pwm, thiab laminator kub, cov qauv xov tooj, thiab cov nplaum.
3.
4. Nws sib xyaw: lub taub hau sib xyaw ntawm lub siab-} kev siv tshuab npuas yuav tsum muaj cov khoom siv raw kom huv si.
5.
6. Cov tawv nqaij Pretreatment: Xyuas kom cov tawv nqaij saum npoo av huv thiab qhuav. Thov cov kua nplaum lossis ua cov tshuaj tiv thaiv saum npoo av yog tias tsim nyog los txhim kho adhesion.
7. Kho lub sijhawm thiab cov xwm txheej: Ua kom lub sijhawm kho thiab tsim nyog ib puag ncig kom ua tiav kev ua npuas dej zoo.
8. Kev ceev faj kev nyab xeeb: Tshwj xeeb tshaj yog thaum siv isocyanates, ib qho kev tiv thaiv zoo tshaj plaws, tus kheej tiv thaiv tus kheej e
