Vinyl Acetate Monomer (Sinopec VAM)
Vinyl acetate kana vinyl acetate monomer (VAM) inonyanya kushandiswa semonomer mukugadzirwa kwemamwe makemikari anoshandiswa mumhando dzakasiyana dzeindasitiri nevatengi zvigadzirwa.
Chii chinonzi Monomer?
A monomer imorekuru rinogona kusungirirwa kune mamwe mamorekuru akafanana kuti aumbe polima.
VAM-based polymers, kusanganisira vinyl chloride-vinyl acetate copolymer, polyvinyl acetate (PVA) uye polyvinyl doro (PVOH), anoshandiswa mumhando dzakasiyana dzekushandisa.
Kana mapolymers achigadzirwa uchishandisa VAM, iyo vinyl acetate inoshandiswa mukugadzira kwavo inopedzwa zvachose, zvinoreva kuti pane chasara chete kana paine mukana wekuratidzwa kuVAM pachayo mune izvi zvigadzirwa.
● Zvokunamira uye Zvokunamatira: PVA ine zvinhu zvakasimba zvekunamira zvinhu zvakasiyana-siyana, zvinosanganisira mapepa, matanda, mafirimu epurasitiki nesimbi, uye chinhu chinokosha pakugadzira namo yemapuranga, guruu jena, guruu romuvezi uye guruu rechikoro.PVOH inoshandiswa kunamatira kurongedza mafirimu;inonyungudika nemvura uye inoramba ichichinja-chinja sezvainokura.
● Paints: VAM-based polymers inoshandiswa mukugadzirwa kwemavara akawanda emukati latex sechinhu chinopa kunamatira kwezvinhu zvose uye kupenya kwekupedzisa.
● Micheka: PVOH inoshandiswa mukugadzira micheka yewarp size, nzira iyo micheka inoputirwa nefirimu inodzivirira kuderedza kuputsika panguva yekuruka.
● Coatings: PVOH inoshandiswa mumifananidzo yemifananidzo.Inoshandiswawo mukugadzira polyvinyl butyral (PVB), resin ine yakasimba adhesion, kujeka uye kuoma zvinhu.PVB inonyanya kushandiswa mugirazi laminated yemotokari uye zvivakwa zvekutengesa;inopa inodzivirira uye yakajeka interlayer inosungirirwa pakati pemapani maviri egirazi.Inogonawo kushandiswa mukuvhara uye inki.VAM-based derivatives inoshandiswawo seyekuputira mumafirimu epurasitiki ekurongedza chikafu.
● Food Starch Modifier: VAM inogona kushandiswa sechinhu chekudya chekudya starch modifiers.Yakagadziridzwa chikafu starch chinowanzo shandiswa sekuwedzera kwechikafu nekuda kwezvikonzero zvimwechete zvakajairwa masitachi anoshandiswa: kukobvu, kudzikamisa kana kumisa zvigadzirwa zvechikafu senge soups, sosi uye muto.
● Makobvu: PVOH inoshandiswa seyakakora mune zvimwe zvinwiwa.Zvinwiwa zvinogona kuwedzerwa kune zvimwe zvinwiwa kubatsira kubata dysphagia, kana kuoma kwekumedza, uye kubatsira zviri mukati mezvinwiwa zvinyoro kuti zvirambe zvakagoverwa.
● Insulation: VAM inopedzwa mukugadzirwa kwe ethylene vinyl acetate (EVA), inoshandiswa mutambo uye tambo yekudzivirira nekuda kwekushanduka kwayo, kusimba uye zvinhu zvayo zvinopisa moto.
● Barrier Resin: Kuwedzera kushandiswa kweVAM kugadzirwa kweethylene vinyl alcohol (EVOH), iyo inoshandiswa sechivhariso chesimbi mukutakura chikafu, mabhodhoro epurasitiki, uye matangi epeturu, uye mumapolymer einjiniya.Barrier resins mapurasitiki anoshandiswa mukurongedza chikafu kubatsira kudzivirira gasi, mhute kana mvura kupinda uye kubatsira kuchengeta chikafu chitsva.
VAM shore tank iri paJiangyin, Nanjing neJingjiang inodarika 10000cbms. Relying on which, yakamisa matangi emahombekombe kuti ishande pamwe chete nevadyidzani vayo vepasi rose uye kupa basa rakanakisa kune vatengi vayo vepasirese.
