3. Tshem tawm cov npuas npuas kom ua tiav adhesion ntawm zaj duab xis thiab substrate, tsis muaj wrinkles.
4. Tso cai kho ntawm chav tsev kub kom ua tiav daim ntawv thov.
Kub- Txheej txheem qhwv (tsim rau qhov tsis zoo li lub qhov rooj, moldings, txee, thiab profiles)
1. Tom qab siv cov nplaum rau lub substrate, muab tso rau hauv lub tshuab wrapping kom preheat zaj duab xis.
2. Siv rab phom cua kub / lub tshuab qhwv kom sov cov zaj duab xis, softening nws thiab ua kom nws elasticity.
3. Siv lub siab rollers kom nruj nreem qhwv zaj duab xis rau ntawm qhov profile lossis embossed nto.
4. Txias thiab teeb tsa, luas thiab ua tiav cov npoo, ua kom muaj kev sib haum xeeb ntawm cov ces kaum thiab grooves yam tsis muaj rov qab.
III. Cov ntsiab lus tseem ceeb rau daim ntawv thov: Siv cov nplaum nplaum nyias thiab sib npaug kom tsis txhob xau lossis sib sau ua ke uas tuaj yeem ua rau npuas thiab wrinkling.
Thaum thov cov yeeb yaj kiab, ua ntej tso nws, tom qab ntawd nias kom ruaj khov, thiab thaum kawg tshem tawm cov npuas npuas.
