Vinyl acetate (VAM)

Sharaxaad:Vinyl acetate (VAC), oo sidoo kale loo yaqaano vinyl acetate, waa walxo kiimiko ah oo muhiim ah oo ceeriin ah.Iyada oo la adeegsanayo is-polymerization ama isku-duubnida monomers kale, vinyl acetate waxay soo saari kartaa alaabada sida khamriga polyvinyl (PVA), vinyl acetate ethylene copolymer (EVA), polyvinyl acetate (PVAc), vinyl acetate vinyl chloride copolymer (EVC), iyo wixii la mid ah.Alaabooyinkani waxay leeyihiin isticmaalyo kala duwan, guud ahaan loo isticmaalo xabagta, waraaqaha ama alaabooyinka cabbiraadda dharka, rinjiga, khadadka, farsamaynta maqaarka, emulsifiers, filimada biyaha ku milma, hagaajinta ciidda iyo wixii la mid ah.

Astaamaha:Firfircoon oo guban kara

Codsiga:

1. Vinyl acetate waa alaabta ceeriin ee ugu weyn ee soo saarista vinyl fiber synthetic.

2. Vinyl acetate waa polymerized lafteeda ama la isku koobay oo leh monomers-hoosaadyo si loo helo khamriga polyvinyl, EVA, EVC, vinyl acetate-acrylonitrile fibers, vinyl acetate-acrylate copolymers, kuwaas oo dhammaantood leh isticmaalka warshadaha muhiimka ah oo si ballaaran loo isticmaalo.Waxa loo istcimaalaa sida xidhe, daahan dhismaha walxaha Kiimikada, cabbirka dunta iyo wakiilka dhamaystirka, wakiilka xoojinta waraaqaha, iyo soo saarida muraayadda badbaadada, iwm.

3. Vinyl acetate waxay la falgashaa ethanol iyo bromine si ay u hesho dhexdhexaadinta daawada Methionazole - bromoacetaldehyde diethyl acetal.

4. Waxaa loo isticmaalaa synthesis fiber resin, iyo sidoo kale loo isticmaalaa sida dhexdhexaad ah iyo xidhe ee saliidda shub dhibic niyad-jabka iyo dhumucdiisuna.

Tilmaamaha guud:Marka la kululeeyo ama hoos yimaada ficilka fiilooyinka indhaha ama peroxides, walaxda waxay u nugul tahay polymerization, oo keenaysa dabka iyo khatarta qaraxa.Waxay si ba'an uga falcelisaa oksaydhiyeyaasha xooggan

Xidhmada:190kg / durbaan, ama shuruudo macmiil ahaan.

Gaadiidka iyo kaydinta:

Ka fogow roobka dhalaalaya iyo heerkulka sare ee gaadiidka,

Ku kaydi alaabta meel qabow, hadh iyo hawo leh, ka fogow dabka.

Heerkulka kaydinta waa inuu ka hooseeyaa 35 ℃.
