Yuav tsum siv pes tsawg GSM ntawm PE coated ntawv rau khob ntawv?

Cov khob ntawv tau dhau los ua ib feem tseem ceeb ntawm peb lub neej txhua hnub thiab siv dav thoob plaws ntiaj teb. Cov khob ntawv tuaj yeem pom txhua qhov chaw, txawm tias nws yog nyob rau hauv kev lag luam noj mov lossis hauv cov chaw nyob xws li cov tuam txhab lossis tsev neeg.

Cov khoom siv tseem ceeb uas siv rau hauv kev tsim cov khob ntawv yog daim ntawv coated PE. PE sawv cev rau polyethylene, ib qho thermoplastic polymer uas muab lub khob nrog ib txheej tsis pub dej nkag. Cov txheej no ua kom lub khob ruaj khov thiab tsis xau, ua rau koj txaus siab rau koj cov dej haus yam tsis muaj kev txhawj xeeb.

GSM (lossis grams ib square meter) yog chav ntsuas uas siv los txiav txim qhov hnyav thiab tuab ntawm daim ntawv. Qhov siab dua GSM, daim ntawv tuab dua thiab ruaj dua. Rau cov khob ntawv, GSM nyob rau hauv qhov ntau ntawm 170 txog 350 yog siv feem ntau. Cov khoom no ua kom ntseeg tau tias cov khob yog qhov sib npaug zoo meej ntawm kev ruaj khov thiab kev ywj pheej, ua rau lawv yooj yim tuav thiab tiv thaiv kev xau.

Tiam sis vim li cas GSM thiaj tseem ceeb rau cov khob ntawv? Lub hom phiaj tseem ceeb, yog li ntawd, yog xyuas kom lub khob tuav tau qhov hnyav ntawm cov dej haus thiab tsis lwj lossis tawg vim yog dej noo. GSM siab dua muab lub khob nrog lub zog thiab kev ruaj khov, xyuas kom meej tias nws tuaj yeem tuav cov kua kub yam tsis muaj teeb meem. Ntawm qhov tod tes, GSM qis dua yuav ua rau lub khob tsis khov thiab yooj yim xau.

Cov txheej txheem ntawm PE-txheej cov ntawv yob loj siv rau kev tsim cov khob ntawv. Cov txheej txheem no suav nrog txheej polyethylene txheej rau daim ntawv kom txhim kho nws cov khoom tiv thaiv dej thiab rwb thaiv tsev. Cov txheej txheem PE tiv thaiv cov dej noo kom tsis txhob nkag mus rau hauv daim ntawv thiab tswj qhov kub zoo rau cov dej haus, ua kom lawv kub lossis txias ntev dua.

Nws yog ib qho tseem ceeb heev uas cov txheej PE yuav tsum tau siv rau ntawm daim ntawv. Qhov no ua kom lub khob tsis xau thiab tsis txhob muaj kev nchuav. Qhov tuab ntawm cov txheej PE feem ntau yog 10 txog 20 microns, nyob ntawm seb lub khob zoo thiab kev ua haujlwm zoo li cas. Daim ntawv PE-coated no feem ntau hu ua “daim ntawv PE coated ib sab” lossis “daim ntawv PE coated ob sab”, nyob ntawm seb cov txheej no siv rau qhov twg.

Ntxiv rau GSM thiab PE txheej, lwm yam tseem cuam tshuam rau qhov zoo thiab kev ua haujlwm ntawm cov khob ntawv. Qhov zoo ntawm cov khoom siv raw ntawm khob ntawv, cov txheej txheem tsim khoom thiab kev tsim qauv ntawm lub kiv cua khob ntawv ua lub luag haujlwm tseem ceeb. PaperJoy tau tsim cov ntawv PE coated, kiv cua khob ntawv thiab lwm yam khoom siv khob ntawv rau 17 xyoo, thiab muab cov qauv dawb kom koj tuaj yeem paub zoo dua txog qhov zoo meej ntawm cov khoom.
