Vinyl Acetate Monomer (Sinopec VAM)
Vinyl acetate kapa vinyl acetate monomer (VAM) e sebelisoa haholo joalo ka monoma ha ho etsoa lik'hemik'hale tse ling tse sebelisoang lits'ebetsong tse fapaneng tsa indasteri le lihlahisoa tsa bareki.
Monomer ke eng?
Monomere ke molek'hule e ka kopanngoang le limolek'hule tse ling tse tšoanang ho etsa polymer.
Li-polymers tse thehiloeng ho VAM, ho kenyelletsa le vinyl chloride-vinyl acetate copolymer, polyvinyl acetate (PVA) le polyvinyl alcohol (PVOH), li sebelisoa lits'ebetsong tse fapaneng.
Ha li-polymer li etsoa ho sebelisoa VAM, vinyl acetate e sebelisoang ha e etsoa e sebelisoa ka ho feletseng, ho bolelang hore ho na le masala feela haeba ho ka ba le monyetla oa ho pepesehela VAM ka boeona lihlahisoa tsena.
● Likhomaretsi le Likhomaretsi: PVA e na le matla a ho khomarela lintho tse ngata tse fapaneng, tse akarelletsang pampiri, lepolanka, lifilimi tsa polasetiki le tšepe, ’me ke motsoako o ka sehloohong oa sekhomaretsi sa lehong, sekhomaretsi se sesoeu, sekhomaretsi sa ’metli le sekhomaretsi sa sekolo.PVOH e sebelisetsoa lifilimi tsa liphutheloana tse khomarelang;e qhibiliha ka metsing 'me e lula e tenyetseha ha e ntse e tsofala.
● Lipente: Li-polymers tse thehiloeng ho VAM li sebelisoa ha ho etsoa lipente tse ngata tsa ka hare tsa latex e le motsoako o fanang ka ho khomarela lisebelisoa tsohle le ho khanya ha qetello.
● Textiles: PVOH e sebelisoa ha ho etsoa masela bakeng sa ho roka, e leng mokhoa oo masela a koahetsoeng ka filimi e sireletsang ho fokotsa ho senya nakong ea ho loha.
● Li-coatings: PVOH e sebelisoa ho li-photosensitive coatings.E boetse e sebelisoa ha ho etsoa polyvinyl butyral (PVB), resin e nang le matla a ho khomarela, ho hlaka le ho tiea.PVB e sebelisoa haholo ka khalase ea laminated bakeng sa likoloi le mehaho ea khoebo;e fana ka interlayer e sireletsang le e bonaletsang e kopantsoeng pakeng tsa likarolo tse peli tsa khalase.E ka boela ea sebelisoa ka li-coatings le li-inks.Li-derivatives tse thehiloeng ho VAM li boetse li sebelisoa e le ho roala lifiliming tsa polasetiki bakeng sa ho paka lijo.
● Food Starch Modifier: VAM e ka sebelisoa e le motsoako oa ho fetola starch ea lijo.Setache sa lijo se fetotsoeng hangata se sebelisoa e le tlatsetso ea lijo bakeng sa mabaka a tšoanang le a tloaelehileng a li-starch a sebelisoa: ho tenya, ho tsitsisa kapa ho etsa lihlahisoa tsa lijo tse kang sopho, li-sauces le gravy.
● Li-thickeners: PVOH e sebelisoa e le ntho e tiisang metsi a mang.Li-thickening agents li ka eketsoa ho lino tse ling ho thusa ho phekola dysphagia, kapa bothata ba ho metsa, le ho thusa likahare tsa lino-mapholi hore li lule li arotsoe ka ho lekana.
● Insulation: VAM e sebelisoa ha ho etsoa ethylene vinyl acetate (EVA), e sebelisoang ho kenya terata le cable ka lebaka la ho tenyetseha ha eona, ho tšoarella ha eona le thepa ea eona e thibelang mollo.
● Barrier Resin: Tšebeliso e ntseng e eketseha ea VAM ke ho etsoa ha ethylene vinyl alcohol (EVOH), e sebelisoang e le lesela le thibelang ho paka lijo, libotlolong tsa polasetiki le litankeng tsa peterole le ho lipolima tsa boenjiniere.Li-barrier resin ke lipolasetiki tse sebelisoang ho paka lijo ho thusa ho thibela khase, mouoane kapa ho kenella ha metsi le ho thusa ho boloka lijo li le ncha.
Tanka ea lebopo ea VAM e fumanehang Jiangyin, Nanjing le Jingjiang ho feta 10000cbms. Ho itšetlehile ka eona, ho thehile litanka tsa lebōpo ho sebetsa haufi-ufi le balekane ba eona ba machaba le ho fana ka tšebeletso e molemo ka ho fetisisa ho bareki ba eona ba lefats'e.
