IVinyl Acetate Monomer (Sinopec VAM)
I-Vinyl acetate okanye i-vinyl acetate monomer (i-VAM) isetyenziswa ngokuyinhloko njenge-monomer kwimveliso yezinye iikhemikhali ezisetyenziswa kwiimveliso ezahlukeneyo kunye nemveliso yabathengi.
Yintoni iMonomer?
I-monomer yimolekyuli enokuthi idityaniswe kwezinye iimolekyuli ezifanayo ukwenza i-polymer.
Iipolymers ezisekelwe kwi-VAM, kuquka i-vinyl chloride-vinyl acetate copolymer, i-polyvinyl acetate (PVA) kunye ne-polyvinyl alcohol (PVOH), isetyenziswe kwiinkqubo ezahlukeneyo.
Xa iipolymers zenziwe kusetyenziswa i-VAM, i-acetate ye-vinyl esetyenziselwa ukwenziwa kwayo idliwe ngokupheleleyo, oku kuthetha ukuba kukho intsalela kuphela ukuba kukho ukuvezwa okunokwenzeka kwi-VAM ngokwayo kwezi mveliso.
● I-Adhesives kunye neGlues: I-PVA ineempawu eziqinileyo zokubambelela kwizinto ezahlukeneyo, eziquka iphepha, umthi, iifilimu zeplastiki kunye neentsimbi, kwaye isithako esiphambili kwiglue yomthi, iglu emhlophe, iglu yomchweli kunye neglu yesikolo.I-PVOH isetyenziselwa iifilimu zokupakisha ezinamathele;iyanyibilika emanzini kwaye ihlala ibhetyebhetye njengoko isidala.
● Iipeyinti: Iipolymers ezisekelwe kwi-VAM zisetyenziselwa ukuveliswa kweepeyinti ezininzi ze-latex zangaphakathi njengesithako esinika ukubambelela kuzo zonke izithako kunye nokukhanya kokugqiba.
● Iimpahla: I-PVOH isetyenziselwa ukuveliswa kwempahla yokulinganisa i-warp size, inkqubo apho iingubo zifakwe kwifilimu ekhuselayo ukunciphisa ukuphuka ngexesha lokuluka.
● Iingubo: I-PVOH isetyenziswe kwiingubo ze-photosensitive.Ikwasetyenziswa ekwenzeni i-polyvinyl butyral (PVB), i-resin ene-adhesion eyomeleleyo, ukucaca kunye neempawu zokuqina.I-PVB isetyenziswa kakhulu kwiglasi elaminethiweyo kwiimoto kunye nezakhiwo zorhwebo;ibonelela ngokhuselo kunye ne-interlayer engafihliyo edityaniswe phakathi kweepaneli ezimbini zeglasi.Inokusetyenziswa kwakhona kwiingubo kunye neenki.I-VAM-based derivatives nayo isetyenziswa njengengubo kwiifilimu zeplastiki zokupakisha ukutya.
● Isilungisi seSitatshi soKutya: I-VAM ingasetyenziswa njengesithako kwizilungisi zesitatshi sokutya.Isitatshi sokutya esilungisiweyo siqhele ukusetyenziswa njengesongezo sokutya ngenxa yezizathu ezifanayo ezisetyenziswayo: ukujiya, ukuzinzisa okanye ukumilisela iimveliso zokutya ezifana neesuphu, iisosi kunye negravy.
● Izinto ezityebisayo: I-PVOH isetyenziswa njengesixhobo sokujiya kolunye ulwelo.Ii-agent ezityebisayo zingongezwa kulwelo oluthile ukunceda ukunyanga i-dysphagia, okanye ubunzima bokuginya, kunye nokunceda imixholo yeziselo ezithambileyo zihlale zisasazwa ngokulinganayo.
● I-Insulation: I-VAM isetyenziselwa ukwenziwa kwe-ethylene vinyl acetate (EVA), esetyenziswa kwi-wire kunye ne-cable insulation ngenxa yokuguquguquka kwayo, ukuqina kunye neempawu zayo zokunqanda umlilo.
● I-Barrier Resin: Ukusetyenziswa okukhulayo kwe-VAM kukuveliswa kwe-ethylene vinyl alcohol (EVOH), esetyenziswa njengentlaka yesithintelo ekupakisheni ukutya, kwiibhotile zeplastiki, nakwiitanki zepetroli nakwizipholima zobunjineli.Iiresin zokuthintela ziiplastiki ezisetyenziselwa ukupakishwa kokutya ukunceda ukuthintela igesi, umphunga okanye ukungena kolwelo kunye nokunceda ukugcina ukutya kusitsha.
Itanki yonxweme ye-VAM ebekwe eJiangyin, eNanjing naseJingjiang ngaphezu kwe-10000cbms.Ukuxhomekeka apho, kwasekwa amatanki onxweme ukuze asebenze ngokusondeleyo kunye namaqabane ayo ngamazwe kunye nokubonelela ngeyona nkonzo ingcono kubathengi bayo behlabathi.
