Lub hauv paus ntawm Membrane Hloov: Khoom

Muaj peb yam khoom tseem ceeb siv rau kev hloov pauv membrane

Khoom siv: Polycarbonate (PC)

Hom tau zoo :

Kub-resistant - 60 ~ 120 ℃, thickness 0.125 ~ 1.2, du nto, siab transmittance, ib puag ncig tiv thaiv, tsis tshua muaj dej nqus, zoo seem stability, zoo heev dabtsi yog khoov, tensile thiab compressive zog, zoo heev kub tsis kam, txias tsis kam, hluav taws xob rwb thaiv tsev thiab atmospheric laus. tsis kam. Nws tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm feem ntau cov membrane hloov vaj huam sib luag, thiab kev xa tawm siab ntawm PC tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm lub qhov rais LCD.

Qhov tsis zoo:

Cov tshuaj tiv thaiv (organic hnyav) tsis zoo, qaug zog ua haujlwm tsis zoo, kev ntxhov siab tawg yooj yim tshwm sim, huab cua oxidation yog ib qho yooj yim kom maj mam tsim cov txheej txheej ntog, txiav txim siab los ntawm ib puag ncig, thiab thaum kawg maj mam decomposed. Lub sijhawm kev puas tsuaj rau lub cev yog 3-8 xyoo.

Khoom siv: Polyester (poly (ethylene phthalate) (PET))

Hom tau zoo :

Kub tiv taus - 30 ~ 160 ℃ / thickness 0.075 ~ 0.25 / du, zoo tshuaj tiv thaiv.

Nws muaj cov khoom siv zoo heev, rwb thaiv tsev, kub tsis kam, hardness thiab lub zog loj tshaj plaws thiab lub zog ntawm cov thermoplastic, zoo heev hnav tsis kam thiab kev sib txhuam tsis kam, tshwj xeeb tshaj yog nrog khoov tsis kam thiab siab elasticity, thiab siab seem stability.

The tensile strength is comparable to that of aluminum film, much higher than that of PC and PVC. It is the most ideal substrate for making thin film switch circuit. Textured PET is the preferred material for membrane switch panel.

Qhov tsis zoo:

Insoluble nyob rau hauv cov organic solvents, tsis alkali resistant.

Kev nqus dej tsawg.

Textured Tus tsiaj yog kim.

Khoom siv: Polyvinyl chloride (PVC)

Hom tau zoo :

Kub tiv taus -20 ~ 60 ℃ / thickness 0.175 ~ 1.5 / du nto, ruaj khov rau acid, alkali thiab ntsev nyob rau hauv ib txwm kub. Nws muaj kev hnav zoo, nplaim taws ua haujlwm thiab tua tus kheej, tshem tawm suab nrov thiab kev poob siab, thiab cov hluav taws xob zoo.

Qhov tsis zoo:

Tsis zoo thermal stability.
