Kev tswj cov txheej txheem nyuaj
Cov kev ntsuas xws li qhov kub thiab qhov ceev yuav tsum tau ua kom zoo sib xws. Kev tswj tsis raug yuav yooj yim ua rau muaj teeb meem xws li cov ntawv tsis sib xws, qhov tsis sib xws, npuas lossis tawg.
Cov khoom siv siab heev
Nyob rau hauv ib qho - cov kauj ruam ntau lawm, lub hau ntswj extrusion tso zis yuav tsum raug sib npaug nrog tus nqi tuag; txwv tsis pub, nws yuav cuam tshuam cov hmoov dispersion thiab ntau lawm. Cov txheej txheem yog heev nyob ntawm cov khoom raug thiab stability.
Inherent Material txwv
PP / PE cov ntaub ntawv muaj kev txwv nruj thiab kub tsis kam, thiab nthuav tawm cov thermal expansion thiab contraction tseem ceeb thaum lub sij hawm tsim khoom. Qhov no impairs seem stability thiab imposes them nyiaj yuav tsum tau ntawm cov txheej txheem ntau lawm.
Kev Tswj Xyuas Zoo
Qhov teeb meem ntawm kev ua tsis tiav ex-kev tshuaj ntsuam xyuas lub Hoobkas yog muaj nyob rau hauv kev lag luam. Kev tswj xyuas qhov tsis zoo xws li tuab thiab xim tso siab rau siab - cov cuab yeej siv tau zoo thiab cov tshuab tswj kom zoo.
Qhov zoo ntawm cov ntawv hollow, xws li lub teeb yuag thiab ib puag ncig tus phooj ywg, tau coj mus rau lawv daim ntawv thov dav; Txawm li cas los xij, lawv cov txheej txheem tsim khoom nthuav qhia qee yam kev cuam tshuam.
