Umenzi wexabiso eliLungileyo VAE EMULSION(VAE) CAS:24937-78-8

Umenzi Ixabiso Elihle I-VAE EMULSION(VAE) CAS:24937-78-8 Umfanekiso Obonakalayo

inkcazo emfutshane:

I-VAE EMULSION (VAE) ifunyanwa ngokuqokelela i-ethylene kunye ne-ethyl acetate ngokwemilinganiselo eyahlukeneyo. Isifinyezo sesiNgesi se-EVA simele ukwakheka kwe-ethylene, i-VA imele izinto ze-acetate ethylene. Umxholo unxulumene ngokusondeleyo. Ngokwemixholo eyahlukeneyo ye-VA, i-VAE EMULSION (VAE) inokwahlulwa ibe ziindidi ezintathu: umxholo we-VA yi-5% Chemicalbook-40% ebizwa ngokuba yi-EVA plastic, esetyenziswa kakhulu ekuguquleni i-polyethylene, ekwenzeni iingcingo kunye neentambo, iifilimu ezincinci, kunye nezinye iimveliso zokubumba kunye nomxube; Umxholo we-VA yi-40%-90% ebizwa ngokuba yi-EVA rubber, esetyenziswa kakhulu kwirabha, iintambo kunye nezinto zoshishino zeemoto. Umxholo we-VA ungaphezulu kwe-90%, ebizwa ngokuba yi-polyache acetate emulsion lotion, kwaye isetyenziselwa kakhulu izinto zokuncamathelisa, ii-coating, njl.

Izicelo ze-VAE

Yongeza iglue edityanisiweyo-1, i-foam/layout compound kwiglue ekhethekileyo, eyi-vinyl acetate ethylene copolymer lotion esemgangathweni ophezulu. Ine-viscosity yokuqala egqwesileyo kunye nozinzo loomatshini. Xa ithelekiswa ne-polyvinyl acetate lotion, isantya sayo sokunyameka, ukunamathela kunye nezinye iimpawu zokusetyenziswa kwayo zinokuphucuka kakhulu. Inamathela kakuhle kwifilimu yeplastiki kunye ne-aluminium foil, ithambile ngokusisigxina kwii-composites ezisekwe ephepheni, kunye noluhlu olubanzi lweefomyula.

I-ethylene-ethyl acetate communist inokumelana okuhle nempembelelo kunye nokuqhekeka koxinzelelo, ukuthamba, ukuthamba okuphezulu, ukumelana nokubhoboza kunye nokuzinza kweekhemikhali, ukusebenza kakuhle kombane, ukuhambelana okuhle kwezinto eziphilayo, uxinano oluphantsi, kunye nezizalisi, i-retardant flame. I-arhente inokuhambelana okungcono. I-EVA yahlukile kumxholo we-VA, iChemicalBook ukusuka kwiplastiki, irabha, ukuya kwi-emulsion, kwaye uluhlu lwesicelo lubanzi, lufanelekile ukucudiswa, ukubumba ngenaliti, ukuvuthela iplastiki, ukugquma, ukubumba ubushushu kunye nezinye iindlela zokucubungula. Ingasetyenziswa kwiintambo. Izixhobo zokuvala, unyango, ifilimu yokukhusela, iipayipi, izixhobo zepleyiti, izixhobo zokwakha, izixhobo zombane, izixhobo zeemoto kunye nezinto ezifunekayo zemihla ngemihla.

Ifomula yoLwakhiwo lweeMolekyuli:

Iimpawu: Inkcazo emfutshane ye-VAE kukungenisa iqela le-vinyl acetate (VA) kwisakhiwo se-long chain ye-polyethylene (PE), apho umxholo we-VA yeyona nto iphambili echaphazela ukusebenza kwayo, kuba i-VA liqela le-polar. Ngokunyuka komxholo we-VA, i-crystallinity iyancipha, kwaye ukuguquguquka, ukumelana nempembelelo kunye nokumelana neoyile kuyaphucuka. Nangona kunjalo, ngokwanda okufanayo kwe-polarity yayo, ukuhambelana nezizalisi kuyanda, kwaye ukuthintela ilangatye nako kuyanda kancinci.
