Cov khob ntawv tau dhau los ua ib feem tseem ceeb ntawm peb lub neej niaj hnub thiab tau siv dav thoob plaws ntiaj teb.Cov khob ntawv tuaj yeem pom nyob txhua qhov chaw, txawm tias nws yog nyob rau hauv kev lag luam catering lossis hauv cov chaw nyob xws li tuam txhab lossis tsev neeg.
Cov khoom siv tseem ceeb siv hauv kev tsim cov khob ntawv yog PE coated ntawv.PE stands rau polyethylene, ib tug thermoplastic polymer uas muab lub khob nrog ib tug waterproof txheej.Cov txheej no ua kom lub khob nyob ruaj khov thiab tsis muaj pov thawj, tso cai rau koj txaus siab rau koj cov dej haus tsis muaj kev txhawj xeeb.
GSM (lossis grams ib square meter) yog chav ntsuas ntsuas siv los txiav txim siab qhov hnyav thiab tuab ntawm daim ntawv.Qhov siab dua GSM, cov ntawv tuab thiab ruaj khov dua.Rau cov khob ntawv, GSM nyob rau hauv thaj tsam ntawm 170 txog 350 feem ntau yog siv.Qhov kev sau no ua kom ntseeg tau tias lub khob yog qhov sib npaug zoo tshaj plaws ntawm kev ruaj khov thiab yoog raws, ua rau lawv yooj yim los tuav thiab tiv thaiv kom tsis txhob muaj dej.
Tab sis vim li cas GSM ntau yam tseem ceeb rau cov khob ntawv?Lub hom phiaj tseem ceeb, yog li ntawd, yog kom ntseeg tau tias lub khob muaj peev xwm tuav tau qhov hnyav ntawm cov dej haus thiab tsis deform los yog vau vim ya raws.Qhov siab dua GSM muab lub khob nrog lub zog tsim nyog thiab nruj, kom ntseeg tau tias nws tuaj yeem tuav cov kua dej kub yam tsis muaj teeb meem.Ntawm qhov tod tes, GSM qis dua tuaj yeem ua rau lub khob flimsy thiab nws tuaj yeem xau.
Cov txheej txheem ntawm PE-txheej cov ntawv jumbo yob siv rau kev tsim cov ntawv khob.Cov txheej txheem cuam tshuam nrog txheej txheej ntawm daim ntawv nrog ib txheej ntawm polyethylene los txhim kho nws cov dej tsis zoo thiab insulating.PE txheej tiv thaiv cov dej noo los ntawm kev nkag mus rau hauv daim ntawv thiab tswj qhov kub zoo tshaj plaws rau cov dej haus, ua kom lawv kub lossis txias rau ntev.
Nws yog ib qho tseem ceeb heev uas cov txheej txheem PE yog siv sib npaug ntawm daim ntawv.Qhov no ua kom ntseeg tau tias lub khob tseem tsis muaj pov thawj thiab tsis txhob muaj qhov tsis xav tau.Lub thickness ntawm PE txheej yog feem ntau 10 mus rau 20 microns, nyob ntawm seb qhov xav tau zoo thiab kev ua haujlwm ntawm lub khob.Daim ntawv PE-coated no feem ntau hu ua "ib leeg-sab PE coated ntawv" lossis "ob-sided PE coated ntawv", nyob ntawm seb cov txheej txheem siv rau qhov twg.
Ntxiv rau GSM thiab PE txheej, lwm yam tseem cuam tshuam rau tag nrho cov khoom zoo thiab kev ua haujlwm ntawm cov khob ntawv.Qhov zoo ntawm daim ntawv khob raw cov ntaub ntawv, kev tsim khoom thiab tsim cov ntawv khob kiv cua ua lub luag haujlwm tseem ceeb.PaperJoytau tsim PE coated ntawv yob,ntawv khob ntxuamthiab lwm cov ntawv khob raw cov ntaub ntawv rau 17 xyoo, thiab muab cov qauv dawb kom koj tuaj yeem ua tau zoo dua cov txiaj ntsig zoo ntawm cov khoom.
