Dab tsi yog aluminium ntawv ci
Composite aluminium foil yog cov khoom siv ua haujlwm ntawm aluminium ntawv ci thiab lwm yam ntaub ntawv. Nws muaj ntau yam khoom xws li tshuaj tua kab mob, tiv thaiv tshav kub, tiv thaiv corrosion, thiab rwb thaiv tsev kub, thiab yog dav siv hauv kev lag luam, kev tsim kho, ntim khoom noj thiab lwm yam.
Raws li cov khoom siv sib xws, aluminium ntawv ci yog lub teeb, nyias, hloov tau, ua haujlwm zoo thaiv cov kab hluav taws xob ultraviolet thiab kub kub, thiab muaj cov thermal conductivity zoo. Aluminium ntawv ci yog siv ua ke nrog lwm cov ntaub ntawv los muab kev ua si tag nrho rau lawv qhov zoo thiab txhim kho kev ua haujlwm tag nrho.
Dab tsi yog cov ntaub ntawv sib xyaw ntawm cov ntawv txhuas puas?
tus tsiaj
PET, luv luv rau "polyethylene terephthalate," yog ib hom thermoplastic polymer thiab ib tug tswv cuab ntawm tsev neeg polyester. Cov ntaub ntawv PET tau siv dav thoob ntiaj teb, tshwj xeeb tshaj yog hauv kev ntim khoom, fibers thiab engineering plastics.
Thaum sib xyaw nrog aluminium ntawv ci, PET cov ntaub ntawv tuaj yeem muab cov khoom siv zoo, xws li tawv tawv, cuam tshuam tsis kam, thiab ua haujlwm puas; thaum aluminium ntawv ci muab cov khoom thaiv zoo heev, xws li tiv thaiv kev nkag mus ntawm oxygen, noo noo, thiab lub teeb. Cov khoom siv PET / aluminium ntawv ci no feem ntau siv rau hauv ntim khoom noj khoom haus qib siab, tshuaj thiab cov khoom siv tshuaj los xyuas kom meej cov khoom txee lub neej thiab ruaj khov zoo. Tsis tas li ntawd, PET kuj tseem tuaj yeem ua ke nrog ntau cov yeeb yaj kiab los ua cov khoom ntim khoom siv xws li cov cua sov shrink zaj duab xis thiab daim ntawv lo.
Polyethylene / low ntom polyethylene
PE yog hais txog "polyethylene" thiab yog cov khoom siv hluavtaws ntau heev. Nws yog lub siab molecular polymerized los ntawm ethylene monomer. Polyethylene yog dav siv thoob ntiaj teb vim nws lub cev zoo heev thiab kev ruaj ntseg tshuaj.
Polyethylene tuaj yeem muab faib ua ntau hom raws li qhov hnyav molecular, crystallinity thiab branched qauv, xws li:
Tsawg ntom polyethylene (LDPE, low density polyethylene):
Nws muaj qhov yooj yooj yim, ductility thiab pob tshab thiab feem ntau yog siv rau hauv hnab yas, hnab yas, ua liaj ua teb mulch films, hoses thiab lwm yam khoom.
Linear low-density polyethylene (LLDPE, linear low-density polyethylene):
Piv nrog LDPE, cov qauv yog linear ntau dua, cov khoom siv kho tshuab muaj zog dua, thiab cov pob tshab yog me ntsis tsawg. Siv dav hauv cov yeeb yaj kiab yas, hnab yas, cov kav dej, cov ntaub ntawv rwb thaiv tsev cable thiab lwm yam.
High-density polyethylene (HDPE, high-density polyethylene):
Nws muaj lub zog siab, hardness thiab hnav tsis kam, thiab kuj yog kub-resistant. Feem ntau yog siv rau hauv kev tsim cov fwj (xws li tais xab npum fwj, lub raj mis mis), thoob, cov khoom ua si, cov kav dej, cov thawv loj, cov khoom ntim tsis yog khoom noj thiab ntau yam kev lag luam. Yam thiab lwm yam.
Ultra-siab molecular hnyav polyethylene (UHMWPE, ultra-siab molecular hnyav polyethylene):
Nws muaj kev cuam tshuam loj heev, nws tus kheej lubrication thiab hnav tsis kam, thiab feem ntau yog siv rau hauv cov khoom uas muaj kev ua haujlwm siab, xws li cov ntaub ntawv mos mos, cov dej khov nab kuab, cov pob qij txha, cov hlua khi marine thiab cov khoom ua si siab kawg.
PE (polyethylene) thiab txhuas ntawv ci cov ntaub ntawv sib xyaw ua ke ua ke cov yeeb yaj kiab polyethylene thiab aluminium ntawv ci los ntawm cov nplaum lossis lwm cov thev naus laus zis los tsim cov ntaub ntawv sib xyaw nrog ntau yam khoom zoo. Cov khoom siv sib xyaw no ua ke nrog qhov zoo ntawm PE thiab txhuas ntawv ci
PVC / polyvinylidene chloride
PVC yog cov ntawv luv ntawm "Polyvinyl Chloride" thiab yog ib qho khoom siv hluavtaws uas tsim los ntawm cov khoom siv polymerization ntxiv ntawm vinyl chloride monomer (VCM). PVC yog dav siv, tshwj xeeb tshaj yog nyob rau hauv kev tsim kho, ntim, xov hlau thiab cables, khoom siv kho mob, rooj tog kho kom zoo nkauj thiab lwm yam.
PVC (polyvinyl chloride) thiab aluminium foil composite txhais tau hais tias cov khoom siv PVC thiab aluminium ntawv ci yog sib koom ua ke los ntawm cov txheej txheem tshwj xeeb los tsim cov khoom sib xyaw nrog ntau yam khoom. Qhov no PVC aluminium foil composite khoom sib xyaw ua ke zoo ntawm ob qho khoom siv.
