Khoom Description
PVC shrinkage yog dab tsi
PVC shrink zaj duab xis yog ib zaj duab xis ua los ntawm polyvinyl chloride (PVC) resin, uas muaj kev ua haujlwm zoo shrinkage thiab pob tshab. Thaum lub sij hawm ntim cov txheej txheem, los ntawm cua sov PVC shrink zaj duab xis, nws softens thiab shrinks saum npoo ntawm cov khoom ntim, ua tiav sealing, tiv thaiv, thiab zoo nkauj ntxim nyiam.
Qhov zoo tshaj plaws shrinkage kub rau PVC shrink zaj duab xis
Feem ntau, qhov zoo tshaj plaws shrinkage kub rau PVC shrink zaj duab xis yog nruab nrab ntawm 60 degree thiab 80 degree. Nyob rau hauv qhov kub thiab txias no, PVC shrink zaj duab xis tuaj yeem muag sai sai thiab tsis ua rau deformation lossis puas rau cov khoom ntim. Yog tias qhov kub thiab txias qis dhau, PVC shrink zaj duab xis yuav tsis shrink txaus, cuam tshuam cov nyhuv ntim. Yog tias qhov kub thiab txias dhau lawm, PVC shrink zaj duab xis yuav dhau-shrink, ua rau cov khoom ntim khoom puas.
yog vim li cas ntawm shrinkage kub ntawm 60 degree thiab 80 degree
Lub cev muaj zog thiab ua haujlwm tshuab
Lub ntsiab tseem ceeb ntawm PVC shrink zaj duab xis yog polyvinyl chloride resin, uas muaj fluidity zoo thiab plasticity ntawm qhov kub thiab txias, cia nws soften thiab shrinkage sai.
Tib lub sijhawm, cov txheej txheem cua sov ntawm PVC shrink zaj duab xis kuj tso tawm cov cua sov, ntxiv kev txhawb nqa cov nyhuv shrinkage.
Txawm li cas los xij, yog tias qhov kub thiab txias dhau lawm, cov saw hlau molecular ntawm PVC shrink zaj duab xis yuav ua rau tawg ntau dhau, ua rau cov yeeb yaj kiab shrink ua nkig thiab tsis tuaj yeem ua rau tsis tuaj yeem.
1
Thinner shrink zaj duab xis yuav shrink yooj yim dua vim nws zoo thermal conductivity.
2
Yog hais tias qhov saum npoo ntawm cov khoom ntim yog du thiab tsis muaj qhov tsis sib xws, nws tuaj yeem ua kom zoo dua ntawm cov khoom ntim khoom, ua tiav cov txiaj ntsig zoo dua.
3
Lub sij hawm cua sov kom zoo tuaj yeem ua kom cov yeeb yaj kiab softens thiab shrinks tag nrho, tab sis lub sij hawm cua sov ntau dhau yuav ua rau cov khoom ntim tau kub heev, cuam tshuam rau lub ntim zoo.
hauv cov ntsiab lus
Cov ntsiab lus
Qhov zoo tshaj plaws shrinkage kub rau PVC shrink zaj duab xis yog nruab nrab ntawm 60 degree thiab 80 degree. Xaiv qhov tsim nyog shrinkage kub tuaj yeem ua kom lub cev qis thiab ntim cov nyhuv ntawm PVC shrink zaj duab xis, thaum tseem xav txog yam xws li cov yam ntxwv ntawm cov khoom ntim, ntim khoom, thiab kev tsim khoom. Kev siv PVC shrink zaj duab xis kom zoo tuaj yeem txhim kho kev ntim khoom zoo thiab kev tsim khoom, muab kev ruaj ntseg zoo dua rau kev muag khoom thiab kev thauj mus los ntawm cov khoom.
