Vinyl Acetate Monomer (Sinopec VAM)
Vinyl acetate lossis vinyl acetate monomer (VAM) feem ntau yog siv los ua monomer hauv kev tsim khoom ntawm lwm cov tshuaj siv hauv ntau yam kev lag luam thiab cov khoom siv.
Monomer yog dab tsi?
Lub monomer yog ib qho molecule uas tuaj yeem txuas rau lwm cov molecules zoo tib yam los tsim cov polymer.
VAM-based polymers, suav nrog vinyl chloride-vinyl acetate copolymer, polyvinyl acetate (PVA) thiab polyvinyl cawv (PVOH), yog siv ntau yam kev siv.
Thaum cov polymers tau tsim los ntawm VAM, cov yas acetate siv hauv lawv cov chaw tsim khoom yog siv tag nrho, uas txhais tau hais tias tsuas muaj qhov seem yog tias muaj peev xwm raug rau VAM nws tus kheej hauv cov khoom no.
● Adhesives thiab Glues: PVA muaj zog adhesion zog rau ntau yam ntaub ntawv, xws li ntawv, ntoo, yas zaj duab xis thiab hlau, thiab yog ib tug tseem ceeb muaj nyob rau hauv cov kua nplaum ntoo, cov kua nplaum dawb, cov nplaum nplaum thiab cov kua nplaum tsev kawm ntawv.PVOH yog siv rau cov nplaum ntim zaj duab xis;nws yog dej-soluble thiab tseem hloov tau raws li nws muaj hnub nyoog.
● Paints: VAM-raws li polymers yog siv nyob rau hauv zus tau tej cov tha xim sab hauv latex xim raws li cov khoom uas muab adhesion ntawm tag nrho cov khoom xyaw thiab cov luster ntawm lub tiav.
● Textiles: PVOH yog siv nyob rau hauv textile manufacturing rau warp sizing, txheej txheem uas textiles coated nrog ib tug tiv thaiv zaj duab xis kom txo tau tawg thaum lub sij hawm weaving.
● Txheej: PVOH yog siv nyob rau hauv photosensitive txheej.Nws kuj tseem siv rau hauv kev tsim khoom ntawm polyvinyl butyral (PVB), ib qho resin uas muaj zog adhesion, clarity thiab toughness zog.PVB feem ntau yog siv rau hauv cov iav laminated rau tsheb thiab cov tsev lag luam;nws muab kev tiv thaiv thiab pob tshab interlayer uas yog sib koom ntawm ob lub iav ntawm iav.Nws kuj tseem siv tau rau hauv coatings thiab inks.VAM-raws li derivatives kuj tseem siv los ua txheej hauv cov yeeb yaj kiab yas rau ntim khoom noj.
● Food Starch Modifier: VAM tuaj yeem siv los ua cov khoom siv hauv cov khoom noj cov hmoov txhuv nplej siab.Hloov cov hmoov txhuv nplej siab feem ntau yog siv los ua cov khoom noj ntxiv rau tib yam vim li cas cov hmoov txhuv nplej siab tau siv: kom thicken, stabilize lossis emulsify cov khoom noj xws li kua zaub, kua ntses thiab gravy.
● Thickeners: PVOH yog siv los ua tus neeg ua kom tuab hauv qee cov kua.Cov tshuaj ua kom tuab tuaj yeem ntxiv rau qee cov kua dej los pab kho dysphagia, lossis nqos nyuaj, thiab pab cov ntsiab lus ntawm cov dej qab zib kom nyob twj ywm sib npaug.
● Rwb thaiv tsev: VAM yog siv rau hauv kev tsim khoom ntawm ethylene vinyl acetate (EVA), siv nyob rau hauv cov hlau thiab cable rwb thaiv tsev vim nws qhov yooj, durability thiab nws cov nplaim hluav taws xob.
● Barrier Resin: Kev siv VAM loj zuj zus yog kev tsim cov ethylene vinyl cawv (EVOH), uas yog siv los ua cov khoom siv barrier hauv cov ntim khoom noj, lub raj mis yas, thiab cov roj tank, thiab hauv engineering polymers.Barrier resins yog cov yas siv hauv ntim khoom noj los pab tiv thaiv cov pa roj, vapor lossis kua nkag thiab pab ua kom cov zaub mov tshiab.
VAM shore tank nyob rau ntawm Jiangyin, Nanjing thiab Jingjiang ntau tshaj 10000cbms.Relying uas, tsim shore tanks ua hauj lwm zoo dua nrog nws cov neeg koom tes thoob ntiaj teb thiab muab kev pab zoo tshaj plaws rau nws cov neeg siv khoom thoob ntiaj teb.
