Chaw tsim tshuaj paus Zoo Nqe VAE EMULSION (VAE) CAS: 24937-78-8

Chaw Tsim Khoom Zoo Tus Nqi VAE EMULSION (VAE) CAS: 24937-78-8 Duab Tshwj Xeeb

piav qhia luv luv:

VAE EMULSION (VAE) yog tau los ntawm kev sib sau ua ke ethylene thiab ethyl acetate raws li qhov sib txawv. EVA cov lus luv luv lus Askiv sawv cev rau cov khoom sib xyaw ethylene, VA sawv cev rau cov khoom acetate ethylene. Cov ntsiab lus muaj feem cuam tshuam ze. Raws li cov ntsiab lus VA sib txawv, VAE EMULSION (VAE) tuaj yeem muab faib ua peb pawg: cov ntsiab lus VA yog 5% Chemicalbook-40% hu ua EVA yas, uas feem ntau yog siv rau kev hloov kho polyethylene, tsim cov xov hlau thiab cables, zaj duab xis nyias, thiab lwm yam khoom molding thiab sib tov; Cov ntsiab lus VA yog 40% -90% hu ua EVA roj hmab, uas feem ntau yog siv rau roj hmab, cables thiab cov khoom lag luam tsheb. Cov ntsiab lus VA siab dua 90%, uas hu ua polyache acetate emulsion lotion, thiab feem ntau yog siv rau cov nplaum, txheej, thiab lwm yam.

Cov ntawv thov ntawm VAE

Ntxiv cov kua nplaum sib xyaw-1, cov ua npuas ncauj / cov khoom sib xyaw ua ke rau hauv cov kua nplaum tshwj xeeb, uas yog cov tshuaj pleev vinyl acetate ethylene copolymer zoo. Nws muaj qhov viscosity zoo heev thiab kev ruaj khov kho. Piv nrog polyvinyl acetate lotion, nws qhov ceev kho, kev nplaum thiab lwm yam khoom siv tuaj yeem txhim kho tau zoo heev. Nws muaj kev nplaum zoo rau cov yas zaj duab xis thiab cov ntawv ci txhuas, mos tas mus li rau cov ntawv sib xyaw, thiab ntau yam mis.

Ethylene-ethyl acetate communist muaj kev tiv thaiv zoo thiab kev ntxhov siab tawg, mos, siab elasticity, tiv thaiv kev raug thiab tshuaj lom neeg ruaj khov, kev ua haujlwm hluav taws xob zoo, biocompatibility zoo, qis ceev, thiab cov khoom sau, nplaim taws retardant Tus neeg sawv cev muaj kev sib raug zoo dua. EVA txawv ntawm VA cov ntsiab lus, ChemicalBook los ntawm yas, roj hmab, mus rau emulsion, thiab ntau yam kev siv yog dav, haum rau kev zawm, txhaj tshuaj molding, tshuab yas, txheej, kub molding thiab lwm yam kev ua. Nws tuaj yeem siv rau cov cables. Sealing qhov chaw, kev kho mob, insulating zaj duab xis, kav dej, phaj cov ntaub ntawv, cov ntaub ntawv tsim kho, cov khoom siv hluav taws xob, cov khoom siv tsheb thiab cov khoom siv txhua hnub.

Cov Qauv Qauv Molecular:

Cov yam ntxwv: Cov lus piav qhia luv luv ntawm VAE yog qhia txog vinyl acetate (VA) pawg rau hauv cov qauv saw ntev ntawm polyethylene (PE), uas cov ntsiab lus VA yog qhov tseem ceeb tshaj plaws cuam tshuam rau nws cov kev ua tau zoo, vim VA yog pawg polar. Nrog rau kev nce ntawm cov ntsiab lus VA, qhov crystallinity txo qis, thiab qhov yooj ywm, kev cuam tshuam tsis kam thiab kev tiv thaiv roj tau zoo dua. Txawm li cas los xij, nrog rau kev nce ntxiv ntawm nws cov polarity, qhov sib xws nrog cov fillers tau nce ntxiv, thiab qhov hluav taws kub kuj tau nce me ntsis.
