Nyob rau hauv lub ntiaj teb niaj hnub loj hlob ntawm cov khoom siv pov tseg, qhov zoo ntawm cov khob ntawv ib nrab yog qhov tseem ceeb. Cov txheej txheem tsim khoom, pib nrog kev txiav thiab curling ntawm PE yob, ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab kev ncaj ncees thiab kev siv tau ntawm cov khoom kawg. Cov khoom tseem ceeb ntawm cov txheej txheem no yog daim ntawv khob kiv cua thiab PE ntawv yob, uas yog cov khoom siv raw rau kev tsim cov khob ntawv zoo.

Cov ntawv khob taug kev pib nrog kev xaiv txoj caiPE ntawv yob. Tsis tsuas yog cov khoom siv no lub teeb yuag, tab sis nws tseem muab cov khoom tsim nyog los thaiv kom ntseeg tau tias lub khob tuaj yeem tuav cov kua dej tsis muaj dej. Qhov zoo ntawm PE ntawv yob ncaj qha cuam tshuam rau cov txheej txheem txiav, qhov tseeb yog qhov tseem ceeb. Txhua qhov kev tsis sib haum xeeb hauv cov chais tuaj yeem ua rau lub khob tsis zoo thiab qhov loj me, thaum kawg cuam tshuam rau nws qhov kev ua tau zoo.

Thaum daim ntawv txiav rau hauv cov duab xav tau, cov txheej txheem curling los ua si. Cov kauj ruam no yog qhov tseem ceeb vim nws npaj cov npoo ntawm daim ntawv rau kev sib khi, kom lub khob tuaj yeem tiv taus qhov kev siv nruj. Kev koom ua ke cov thev naus laus zis siab tshaj plaws rau hauv cov txheej txheem hemming tuaj yeem txhim kho cov molding zoo ntawm semi-tiav daim ntawv khob. Los ntawm kev ua kom zoo rau qhov ntsuas kub thiab siab siv thaum lub sij hawm hemming, cov tuam ntxhab tuaj yeem ua tiav cov ntug zoo ib yam thiab ruaj khov, uas yog qhov tseem ceeb rau kev tswj xyuas qhov zoo ntawm lub khob.

Hauv cov ntsiab lus, kev txhim kho cov txheej txheem uas tsom mus rau molding zoo, tshwj xeeb tshaj yog siv tau zoo ntawm PE ntawv yob thiab ntawv khob kiv cua, yog qhov tseem ceeb rau kev tsim cov khob ntawv zoo. Los ntawm kev nthuav dav txhua kauj ruam ntawm kev tsim khoom, cov tuam ntxhab tuaj yeem ua kom lawv cov khoom ua tau raws li cov neeg siv khoom xav tau thaum tswj kev ua haujlwm ruaj khov.Yog tias koj muaj lus nug, thov koj xav tiv tauj peb.tiv tauj peb!
