I-vinyl acetate (VAM)

Incazelo:I-Vinyl acetate (VAC), eyaziwa nangokuthi i-vinyl acetate, iyinto ebalulekile yamakhemikhali ephilayo.Ngokusebenzisa i-self polymerization noma i-copolymerization namanye ama-monomers, i-vinyl acetate ingakhiqiza imikhiqizo efana ne-polyvinyl alcohol (PVA), i-vinyl acetate ethylene copolymer (EVA), i-polyvinyl acetate (PVAc), i-vinyl acetate vinyl chloride copolymer (EVC), njalonjalo.Le mikhiqizo inokusetshenziswa okunhlobonhlobo, okuvamise ukusetshenziselwa izinto zokunamathisela, iphepha noma ama-ejenti okulinganisa izindwangu, amapende, oyinki, ukucutshungulwa kwesikhumba, ama-emulsifiers, amafilimu ancibilika emanzini, izithuthukisi zomhlabathi nokunye.

Izici:Iyasebenza futhi iyavutha

Isicelo:

1. I-Vinyl acetate iwumthombo oyinhloko wokwenziwa kwe-synthetic fiber vinylon.

2. I-vinyl acetate i-polymerized ngokwayo noma i-copolymerized nge-sub-monomers ukuze ithole i-polyvinyl alcohol, i-EVA, i-EVC, i-vinyl acetate-acrylonitrile fibers, i-vinyl acetate-acrylate copolymers, konke okunokusetshenziswa okubalulekile kwezimboni futhi asetshenziswa kabanzi.Isetshenziswa njenge-binder, i-ejenti yokwakhiwa kwe-Chemicalbook impahla, i-textile sizing kanye ne-ejenti yokuqedela, i-ejenti yokuqinisa amaphepha, kanye nokwenza ingilazi yokuphepha, njll.

3. I-Vinyl acetate isabela nge-ethanol ne-bromine ukuze ithole okuphakathi kwesidakamizwa i-Methionazole - i-bromoacetaldehyde diethyl acetal.

4. Isetshenziselwa i-resin fibre synthesis, iphinde isetshenziswe njenge-intermediate kanye ne-binder yamafutha athululela iphuzu elicindezelayo kanye ne-thickener.

Amacebiso avamile:Uma ishiswa noma ingaphansi kwesenzo semicu yokubona noma ama-peroxide, into ijwayele ukwenziwa i-polymerization, idale ingozi yomlilo nokuqhuma.Isabela ngobudlova kanye nama-oxidants aqinile

Iphakheji:190kg/drum, noma imfuneko njengeKhasimende.

Ezokuthutha nokugcina:

Gwema imvula eningi kanye nokushisa okuphezulu kwezokuthutha,

Gcina imikhiqizo ezindaweni ezipholile, ezinomthunzi nezinomoya, gcina kude nomlilo.

Izinga lokushisa lesitoreji kufanele libe ngaphansi kuka-35 ℃.
