Kev faib tawm ntawm thermoforming zaj duab xis
1. Cov yeeb yaj kiab shrinking yog siv rau kev muag khoom thiab kev thauj mus los ntawm ntau yam khoom. Lub luag haujlwm tseem ceeb yog ruaj khov, npog thiab tiv thaiv cov khoom. Cov zaj duab xis contraction yuav tsum muaj siab anti-puncture, zoo shrinkability thiab ib tug tej yam contraction kev nyuaj siab, thiab cov zaj duab xis yuav tsis tsim qhov thaum lub sij hawm contraction txheej txheem. Vim tias cov zaj duab xis contraction feem ntau siv sab nraum zoov, tus neeg saib xyuas UV tiv thaiv yuav tsum tau ntxiv. Xws li OPS / PE / PVC / POF / PET shrink zaj duab xis.
2. PE thermal shrinking zaj duab xis yog dav siv nyob rau hauv tag nrho cov sau thiab ntim ntawm caw, kaus poom zaub mov, dej ntxhia, ntau yam dej haus, fabrics thiab lwm yam khoom. Cov khoom no muaj kev ywj pheej zoo, cuam tshuam thiab tsim kua muag, tsis yooj yim rau kev puas tsuaj, tsis ntshai dej ntws, thiab ntsws.
3. PVC zaj duab xis muaj cov yam ntxwv ntawm siab pob tshab, zoo gloss, thiab siab contraction tus nqi.
4. POF muaj lub siab gloss, zoo toughness, siab tsim kua muag zog, uniform thermal contraction, haum rau tsis siv neeg high-speed ntim. Nws yog lwm yam khoom ntawm cov tsoos PVC thermal shrinking zaj duab xis. POF yog lub ntsiab lus ntawm thermal contraction zaj duab xis. POF yog ntau txheej co-squeezing polylefin thermal contraction zaj duab xis. Nws siv linear low-density polyethylene li intermediate layer (LLDPE) thiab hom polypropylene (PP) li txheej sab hauv thiab txheej. Nws yog plasticized thiab squeezed, thiab tom qab ntawd ua los ntawm cov txheej txheem tshwj xeeb, xws li pwm molding thiab npuas.
5. OPS contraction film (directional polystyrene) thermal contraction film yog ib hom tshiab ntawm OPS thermal contraction film ntim khoom, uas ua tau raws li kev tiv thaiv ib puag ncig. OPS thermal contraction zaj duab xis muaj lub zog siab, siab rigidity, ruaj khov zoo thiab zoo luster. Qib thiab pob tshab. Nws yog ib qho yooj yim rau kev ua tiav, yooj yim rau xim, zoo luam ntawv kev ua tau zoo thiab siab printing daws teeb meem. Qhov no yog ib qho kev txhim kho cov khoom siv rau kev ua lag luam txuas ntxiv mus rau cov khoom lag luam uas nrhiav kev luam ntawv zoo nkauj. Vim tias qhov kev cog lus siab thiab lub zog ntawm OPS zaj duab xis, nws tuaj yeem txuas nrog lub thawv ntawm ntau yam duab, yog li nws tuaj yeem tsis tsuas yog luam tawm cov qauv zoo nkauj, tab sis kuj ua tau raws li kev siv cov thawv ntim tshiab ntawm ntau yam duab. Ib zaj duab xis nyias uas tsis muaj tshuaj lom, tsis qab, roj-pov thawj, thiab kev tu cev ntawm cov zaub mov ua rau cov neeg tsim khoom siv qhov muag-catching xim kom ua tiav 360 degree daim ntawv lo tsim, muab kev ua si tag nrho rau kev muaj tswv yim thiab kev xav, thiab tso cai rau cov dej qab zib thiab lwm yam khoom rau daim ntawv lo. Siv vivid ntau dua, ua kom pom cov duab ntawm lub txee, thiab tsim kom muaj lub thawv ntim khoom npaj txhij txog.
6. PET thermal cua sov polyester zaj duab xis Nta: ruaj khov ntawm chav tsev kub, shrinking thaum lub sij hawm cua sov (sab saum toj iav hloov kub), ib-txoj kev thermal contraction tus nqi siab tshaj 70 feem pua.
