PVC tshav kub shrink zaj duab xis yog ua los ntawm PVC resin tov nrog ib lub kaum ob hom ntawm cov khoom pab tom qab tshuab thib ob, uas yog yus muaj los ntawm zoo transparency, shrinkage yooj yim, siab zog, shrinkage tus nqi yuav dawb do hloov raws li cov neeg siv xav tau, muaj zog operability.Nws cov dej tsis zoo, nplaim hluav taws kub, tus nqi qis thiab cov yam ntxwv siab, kuj yog los ntawm cov tuam txhab tsim khoom, cov neeg muag khoom thiab kev siv cov lag luam.
Tam sim no, qhov kev thov txhua xyoo ntawm shrink zaj duab xis rau dej haus, tshuaj pleev ib ce thiab tshuaj yog kwv yees li 1 lab tons, uas qhia txog kev ua lag luam uas tsis tau pom dua.
Nyob rau hauv Suav teb, lub tshav kub shrink zaj duab xis yog tsuas yog siv nyob rau hauv peb lub teb nram qab no.
Hauv kev lag luam ntim dej haus, ntim dej haus, ntim khoom noj, ntim khoom ntim khoom lag luam xav tau tag nrho cov nqi ntawm cov khoom siv hluav taws xob ua kom sov lub raj mis dej haus lub raj mis labeling ntau tshaj 100,000 tons, thiab ntawm qhov nruab nrab txhua xyoo kev loj hlob ntawm 18%.
Nyob rau hauv lub tshav pob ntawm kws tshuaj, lub thermal shrinkable zaj duab xis yog hloov lub thawv, uas zoo heev txo cov nqi ntim ntawm cov kws lag luam.Kev ntim tshuaj feem ntau yog hais txog lub raj mis, lub kaus mom, lub thawv, cov yeeb yaj kiab siv rau ntim tshuaj thiab tshuab kho mob.
Hauv kev ntim npias, cov khoom tsim tawm ntawm npias hauv Suav teb tau tshaj 51.89 lab tons xyoo tas los, xav tau ntau dua 8.2 billion npias fwj.Yog tias 5% ntawm lub raj mis npias siv cov ntaub ntawv thermoshrinkable, qhov kev noj txhua xyoo yuav ncav cuag 50,000 tons, uas yog qhov kev lag luam zoo heev.
Tam sim no, cov ntim yas ntim cov yeeb yaj kiab kub yog ntau pua txhiab tons, nrog rau PVC, PS, PE thiab lwm yam ntaub ntawv, cov PVC yog cov kub shrink zaj duab xis nrog cov khoom lag luam siab tshaj plaws tam sim no.
Txoj kev loj hlob ntawm thermal shrinkage technology txhawb kev lag luam ntawm thermal shrinkage zaj duab xis, uas ua rau PVC thermal shrinkage zaj duab xis npog lub ntim ntawm cov khoom siv hluav taws xob, cov khoom siv kho mob thiab lwm yam lag luam, thiab txhawb kev tsim cov khoom lag luam ntim khoom lag luam.Nyob rau tib lub sijhawm, cov ntawv ntim cua sov, cov hnab ntim khoom kuj tsim.
