I-Vinyl Acetate Monomer (Sinopec VAM)
I-Vinyl acetate noma i-vinyl acetate monomer (i-VAM) isetshenziswa ngokuyinhloko njenge-monomer ekukhiqizeni amanye amakhemikhali asetshenziswa ekusetshenzisweni okuhlukahlukene kwemikhiqizo yezimboni nezabathengi.
Yini i-Monomer?
I-monomer iyi-molecule engahlanganiswa namanye ama-molecule afanayo ukuze akhe i-polymer.
Ama-polymer asekelwe ku-VAM, okuhlanganisa i-vinyl chloride-vinyl acetate copolymer, i-polyvinyl acetate (PVA) ne-polyvinyl alcohol (PVOH), asetshenziswa ezinhlelweni ezihlukahlukene.
Uma ama-polymers enziwa kusetshenziswa i-VAM, i-vinyl acetate esetshenziswa ekukhiqizeni kwawo idliwe ngokuphelele, okusho ukuthi kunensalela kuphela uma kukhona ukuchayeka okungaba khona ku-VAM ngokwayo kule mikhiqizo.
● Izinto Ezinamathelayo Nezinamatheliso: I-PVA inamandla okunamathela ezintweni ezihlukahlukene, okuhlanganisa iphepha, ukhuni, amafilimu epulasitiki nezinsimbi, futhi iyisithako esiyinhloko kuglue yokhuni, ingcina emhlophe, ingcina yombazi kanye neglu yesikole.I-PVOH isetshenziselwa amafilimu okupakisha okunamathelayo;iyancibilika emanzini futhi ihlala iguquguquka njengoba iguga.
● Amapende: Ama-polymer asekelwe ku-VAM asetshenziswa ekukhiqizeni amapende amaningi e-latex angaphakathi njengesithako esinikeza ukunamathela kwazo zonke izithako kanye nokucwebezela kokuqeda.
● Izindwangu: I-PVOH isetshenziswa ekukhiqizweni kwezindwangu ukuze kulungiswe usayizi we-warp, inqubo lapho izindwangu zimbozwa ngefilimu evikelayo ukuze kuncishiswe ukuphuka ngesikhathi sokulukwa.
● Ama-coatings: I-PVOH isetshenziswa kuma-photosensitive coatings.Ibuye isetshenziswe ekwenzeni i-polyvinyl butyral (PVB), inhlaka enamathela ngokuqinile, ukucaca kanye nezakhiwo eziqinile.I-PVB isetshenziswa kakhulu engilazini elaminethiwe ezimotweni nezakhiwo zezentengiselwano;inikeza i-interlayer evikelayo nebonisa ngale ehlanganiswe phakathi kwamafasitelana amabili engilazi.Ingasetshenziswa futhi kuma-coatings kanye noyinki.Okuphuma ku-VAM okusekelwe ku-VAM nakho kusetshenziselwa ukumboza kumafilimu epulasitiki wokupakisha ukudla.
● Isilungisi Sesitashi Sokudla: I-VAM ingasetshenziswa njengesithako ekulungiseni isitashi sokudla.Isitashi sokudla esishintshiwe sivamise ukusetshenziswa njengesengezo sokudla ngenxa yezizathu ezifanayo ezisetshenziswa isitashi esivamile: ukujiya, ukusimamisa noma ukuqinisa imikhiqizo yokudla efana nesobho, amasoso kanye nomhluzi.
● Izikhuni: I-PVOH isetshenziswa njenge-ejenti ejiya kwezinye uketshezi.Ama-ajenti ajiyisayo angengezwa kolunye uketshezi ukusiza ekwelapheni i-dysphagia, noma ubunzima bokugwinya, kanye nokusiza okuqukethwe kweziphuzo ezibandayo ukuthi kuhlale kwabiwe ngokulinganayo.
● I-Insulation: I-VAM isetshenziselwa ukukhiqizwa kwe-ethylene vinyl acetate (EVA), esetshenziswa ekufakeni ucingo nekhebula ngenxa yokuguquguquka kwayo, ukuqina kanye nezici zayo ezivimbela ilangabi.
● I-Barrier Resin: Ukusetshenziswa okukhulayo kwe-VAM ukukhiqizwa kwe-ethylene vinyl alcohol (EVOH), esetshenziswa njenge-barrier resin ekupakisheleni ukudla, emabhodleleni epulasitiki, nasemathangeni kaphethiloli, nasezintweni zamapholymer zobunjiniyela.Ama-barrier resins amapulasitiki asetshenziswa ekufakweni kokudla ukusiza ukuvimbela ukungena kwegesi, umhwamuko noma uketshezi futhi asize ukugcina ukudla kukusha.
I-VAM shore tank etholakala ku-Jiangyin, Nanjing kanye ne-Jingjiang ngaphezu kuka-10000cbms. Ithembele kuyo, isungule amathangi ogwini ukuze isebenzisane kakhulu nabalingani bayo bamazwe ngamazwe futhi inikeze isevisi engcono kakhulu kumakhasimende ayo omhlaba.
