Raws li cov khoom siv dav siv hauv kev lag luam ntim khoom niaj hnub no, cov yeeb yaj kiab shrinkage nyob ntawm nws cov qauv tsim, xaiv cov khoom siv, thiab cov txheej txheem tsim khoom kom ua tiav qhov kev xav tau. Tsim kom raug tsis tsuas yog txhim kho kev ntim khoom tab sis kuj ua tau raws li ntau yam kev xav tau ntsig txog kev tiv thaiv cov khoom, kev nthuav qhia hom, kev nyab xeeb kev thauj mus los, thiab kev ruaj ntseg ib puag ncig. Yog li ntawd, txoj kev loj hlob ntawm shrink zaj duab xis yuav tsum tau saib xyuas ntawm cov khoom siv, shrink kev ua tau zoo, ntim yuav tsum tau, thiab daim ntawv thov tej yam kev mob.
Shrink kev ua tau zoo yog qhov tsim qauv tsim ntawm shrink zaj duab xis. Lub ntsiab feature ntawm shrink zaj duab xis yog nws lub peev xwm los cog lus tusyees thaum rhuab, cia cov zaj duab xis kom nruj haum rau cov khoom nto. Thaum lub sij hawm tsim, shrink ratio, shrink direction, thiab shrink speed yuav tsum tau ua tib zoo tswj. Cov khoom sib txawv thiab cov kev xav tau ntim yuav tsum muaj cov yam ntxwv sib txawv kom ua tiav cov ntim khoom zoo nkauj thaum txo qis wrinkles thiab cov npuas npuas.
Lub zog zaj duab xis yog lwm qhov tseem ceeb tsim kev xav. Thaum lub sij hawm ntim, kev thauj mus los, thiab tuav, cov yeeb yaj kiab shrink yuav tsum tiv taus kev ncab, kev sib txhuam, thiab kev cuam tshuam sab nraud. Yog li ntawd, nws yuav tsum tau zoo tensile zog, tsim kua muag kuj, thiab puncture kuj. Los ntawm kev kho cov khoom formulations thiab zaj duab xis thickness, manufacturers yuav txhim kho tag nrho cov zaj duab xis stability.
Transparency thiab tsos kev ua tau zoo kuj tseem ceeb tsim cov ntsiab lus. Pob tshab shrink zaj duab xis txhim kho cov khoom pom thiab tso cai rau cov neeg siv khoom kom pom meej cov ntsiab lus ntim. Rau cov khoom lag luam uas xav tau kev txhawb nqa, cov khoom nto yuav tsum tau tsim los xyuas kom meej cov ntawv luam tawm, duab, thiab logos.
Kev ua tau zoo ib puag ncig tau dhau los ua ib qho tseem ceeb hauv kev tsim cov yeeb yaj kiab niaj hnub. Nrog rau kev txhim kho cov ntsiab lus ntim khoom ruaj khov, cov neeg tsim qauv tau tsom mus rau kev rov ua dua tshiab, kev tsim khoom huv si, thiab cov qauv ua yeeb yaj kiab sib sib zog nqus. Kev siv cov ntaub ntawv zoo ib puag ncig thiab kev tsim cov yeeb yaj kiab zoo tuaj yeem txo cov peev txheej thiab txhim kho kev ruaj khov.
Nyob rau hauv cov nqe lus ntawm kev tsim cov ntaub ntawv, shrink film yog tsim los ntawm cov ntaub ntawv polymer. Cov khoom sib txawv muab cov yam ntxwv sib txawv. Cov ntaub ntawv muaj xws li PVC, PE, PET, thiab POF.
PVC shrink zaj duab xis muab cov pob tshab zoo, yoog raws, thiab kev ua haujlwm zoo. Nws tau siv dav hauv kev ntim khoom ua ntej, suav nrog cov khoom ntim txhua hnub thiab cov ntim khoom zoo nkauj. Txawm li cas los xij, nws txoj kev siv tau dhau los txwv vim muaj kev xav tau ib puag ncig.
PE shrink zaj duab xis muab kev yooj yim heev, cuam tshuam tsis kam, thiab tensile kev ua tau zoo. Nws yog qhov tsim nyog rau kev ntim khoom loj, ntim khoom thauj, thiab daim ntawv thov yuav tsum muaj kev tiv thaiv zoo. Nws toughness pab txo kev puas tsuaj thaum lub sij hawm ntim khoom.
PET shrink zaj duab xis nta lub zog txhua yam, ua haujlwm kub, thiab pob tshab. Nws yog dav siv nyob rau hauv daim ntawv thov uas yuav tsum tau ntau dua ntim kev ua tau zoo, xws li haus dej haus daim ntawv lo, electronics khoom ntim, thiab hwm cov khoom ntim. Nws muab qhov ntev ruaj khov thiab zoo heev tsos.
POF shrink zaj duab xis yog ib puag ncig tus phooj ywg shrink khoom nrog siab transparency, zoo toughness, thiab muaj zog kev nyab xeeb kev ua tau zoo. Nws yog dav siv hauv ntim khoom noj, ntim khoom txhua hnub, thiab ntim khoom muag. Piv nrog rau qee cov ntaub ntawv ib txwm siv, POF shrink zaj duab xis zoo dua raws li qhov xav tau ntawm kev ntim khoom ruaj khov.
Tsis tas li ntawd, cov khoom siv ntxiv xws li tshuaj tiv thaiv- cov tshuaj tiv thaiv zoo li qub, UV- cov ntaub ntawv tiv thaiv, thiab cov tshuaj tiv thaiv - pos huab tuaj yeem raug ntxiv raws li cov ntawv thov tshwj xeeb los txhim kho kev ua haujlwm hauv ib puag ncig tshwj xeeb.
Zuag qhia tag nrho, shrink zaj duab xis tsim yuav tsum muaj kev xav txog kev ua haujlwm ntawm lub ntsws, lub zog, pob tshab, kev cuam tshuam ib puag ncig, thiab kev ua kom haum. Cov khoom xaiv ncaj qha txiav txim siab qhov kawg ntawm zaj duab xis. Los ntawm kev tsim qauv thiab kev xaiv cov khoom tsim nyog, cov yeeb yaj kiab shrinkage tuaj yeem muab tus nqi ntau dua hauv kev tiv thaiv cov khoom, kev ntim khoom, thiab kev txhim kho ntim ruaj khov.
