Raws li kev ua tau zoo thiab kev pabcuam kev ua haujlwm ntawm lub khob ntawv, daim ntawv khob lub hauv paus ntawv yuav tsum ua raws li cov hauv qab no:
1. Muaj zog tiv thaiv dej
Lub khob ntawv yog ua tsis muaj dej seepage thiab to
2. Yooj yim ua formability
Thaum ua cov khob ntawv, kom tsis txhob muaj ntawv jam thiab wrinkling thaum lub sij hawm tsim khoom, thiab lub khob ntawv tsim tsis yooj yim rau deform, nws yuav tsum tau hais tias lub hauv paus ntawv ntawm lub khob ntawv muaj siab rigidity, zoo flatness, tsim nyog xoob thickness. , thiab yog ib qho yooj yim rau txheej txheem thiab daim ntawv.
3. Daim ntawv nto fineness
Nws yuav tsum tau tswj xyuas qhov roughness tus nqi ntawm cov ntawv hauv paus yuav tsum tau luam tawm lossis coated PE kom ua tau raws li qhov xav tau los ntawm qhov chaw luam ntawv ntawm lub khob ntawv.
