Soo saaraha Qiimaha Wanaagsan VAE EMULSION(VAE) CAS: 24937-78-8

sharaxaad gaaban:

VAE EMULSION (VAE) waxaa lagu helaa iyadoo la ururiyo ethylene iyo ethyl acetate iyadoo loo eegayo saamiyo kala duwan.Soo gaabinta Ingiriisiga EVA waxay u taagan tahay ka kooban ethylene, VA waxay u taagan tahay qaybaha ethylene acetate.Waxa ku jira ayaa si dhow ula xidhiidha.Marka loo eego waxyaabaha kala duwan ee VA, VAE EMULSION(VAE) waxa loo qaybin karaa saddex qaybood: ka kooban VA waa 5%Chemicalbook-40% loo yaqaan EVA plastic, kaas oo inta badan loo isticmaalo wax ka beddelka polyetylen, fiilooyinka wax soo saarka iyo fiilooyinka, filimada khafiifka ah, iyo alaabada kale ee wax lagu dhejiyo iyo isku dhafka;Waxyaabaha ku jira VA waa 40%-90% loo yaqaan 'EVA rubber', kaas oo inta badan loo isticmaalo caag, fiilooyinka iyo qaybaha warshadaha baabuurta.Waxyaabaha ku jira VA waxay ka sarreeyaan 90%, taas oo loo yaqaan 'polyache acetate emulsion lotion', waxaana inta badan loo isticmaalaa xabagta, dahaarka, iwm.

Codsiyada VAE

Ku dar xabagta isku-dhafka ah-1, xarunta xumbo/qaabaynta koolada gaarka ah, taas oo ah kareemka vinyl acetate ethylene copolymer oo tayo sare leh.Waxay leedahay viscosity bilow aad u fiican iyo xasilloonida farsamada.Marka la barbardhigo kareemka polyvinyl acetate, xawaarihiisa daawaynta, adhesion iyo sifooyinka kale ee codsiga si weyn ayaa loo horumarin karaa.Waxay leedahay adhesion wanaagsan oo ku saabsan filim caag ah iyo aluminium aluminium, jilicsanaan joogto ah oo ku salaysan waraaqaha ku salaysan, iyo noocyo kala duwan oo qaacido ah.

Ethylene-ethyl acetate communist waxay leedahay saameyn wanaagsan oo iska caabin ah iyo dildilaaca cadaadiska, jilicsanaanta, dabacsanaanta sare, ka hortagga daloolada iyo xasiloonida kiimikada, waxqabadka korantada ee wanaagsan, biocompatibility wanaagsan, cufnaanta hoose, iyo buuxinayaasha, ololka ololka Wakiilku wuxuu leeyahay iswaafajin wanaagsan.EVA way ka duwan tahay nuxurka VA, Kiimikada Kiimikada ka caagga ah, caag, si emulsion, iyo kala duwan ee codsiga waa ballaaran, ku haboon tuujin, qaabaynta irbado, caag afuufaya, daahan, qaabaynta kulaylka iyo hababka kale ee processing.Waxaa lagu dabaqi karaa fiilooyinka.Qaybaha daboolka, daryeelka caafimaadka, filimka dahaarka, tuubooyinka, alaabta saxanka, qalabka dhismaha, qalabka korontada, qalabka baabuurta iyo waxyaabaha maalinlaha ah.

Miisaanka Molecular: 342.43

Qaab-dhismeedka Molecular:

Astaamaha: Sharaxaadda gaaban ee VAE waa in lagu soo bandhigo kooxda vinyl acetate (VA) qaabdhismeedka silsiladda dheer ee polyetylen (PE), kaas oo ka kooban VA uu yahay qodobka ugu weyn ee saameeya waxqabadkiisa, sababtoo ah VA waa koox polar ah.Kordhinta maadada VA, crystallinity ayaa hoos u dhacda, dabacsanaanta, caabbinta saameynta iyo caabbinta saliidda ayaa la hagaajiyaa.Si kastaba ha noqotee, korodhka u dhigma ee xayndaabkeeda, iswaafajinta buuxinta waa la kordhiyaa, dib-u-dhacyada ololkuna sidoo kale wax yar ayaa kordhay.
