Vinyl Acetate Monomer (Sinopec VAM)
Vinyl acetate ko vinyl acetate monomer (VAM) ana amfani dashi da farko azaman monomer a cikin samar da wasu sinadarai da ake amfani da su a aikace-aikacen samfuran masana'antu da mabukaci daban-daban.
Menene monomer?
Monomer kwayar halitta ce da za a iya haɗa ta da wasu kwayoyin halitta iri ɗaya don samar da polymer.
Ana amfani da polymers na tushen VAM, gami da vinyl chloride-vinyl acetate copolymer, polyvinyl acetate (PVA) da polyvinyl barasa (PVOH), a aikace-aikace iri-iri.
Lokacin da ake yin polymers ta amfani da VAM, vinyl acetate da aka yi amfani da su wajen kerar su yana cinyewa gaba ɗaya, wanda ke nufin cewa akwai saura kawai idan duk wani yuwuwar bayyanar VAM kanta a cikin waɗannan samfuran.
● Adhesives da Glues: PVA yana da kaddarorin mannewa mai ƙarfi don abubuwa daban-daban, waɗanda suka haɗa da takarda, itace, fina-finai na filastik da karafa, kuma shine maɓalli mai mahimmanci a cikin manne itace, manne fari, mannen kafinta da mannen makaranta.Ana amfani da PVOH don fina-finai na manne;yana da ruwa mai narkewa kuma ya kasance mai sassauƙa yayin da yake tsufa.
● Paints: Ana amfani da polymers na tushen VAM a cikin samar da yawancin fenti na latex na ciki a matsayin abin da ke ba da mannewa da duk abubuwan da ke ciki da kuma haske na gamawa.
● Yadudduka: Ana amfani da PVOH a masana'antar yadi don daidaita girman warp, tsarin da aka rufe kayan yadi da fim mai kariya don rage karyewa yayin saƙa.
● Rufi: Ana amfani da PVOH a cikin suturar hotuna.Hakanan ana amfani dashi wajen kera butyral polyvinyl (PVB), resin da ke da ƙarfi mai ƙarfi, tsabta da kaddarorin tauri.An fi amfani da PVB a cikin gilashin da aka yi da katako don motoci da gine-ginen kasuwanci;yana ba da madaidaicin tsaka-tsaki mai karewa da bayyananne wanda ke haɗe tsakanin fakiti biyu na gilashi.Hakanan ana iya amfani dashi a cikin sutura da tawada.Hakanan ana amfani da abubuwan da suka samo asali na VAM azaman sutura a cikin fina-finan filastik don marufi na abinci.
● Mai gyara sitaci na Abinci: Ana iya amfani da VAM azaman sinadari a cikin masu gyara sitaci na abinci.Ana amfani da sitacin abinci da aka gyaggyara azaman ƙari na abinci saboda dalilai guda ɗaya da ake amfani da sitaci na al'ada: don kauri, daidaitawa ko haɓaka samfuran abinci kamar miya, miya da miya.
● Masu kauri: Ana amfani da PVOH azaman wakili mai kauri a wasu ruwaye.Ana iya ƙara abubuwa masu kauri zuwa wasu ruwaye don taimakawa wajen magance dysphagia, ko wahalar haɗiye, da kuma taimakawa abubuwan abubuwan sha masu laushi su kasance daidai da rarrabawa.
● Insulation: Ana amfani da VAM a cikin samar da ethylene vinyl acetate (EVA), wanda aka yi amfani da shi a cikin waya da kebul na igiya saboda sassaucin ra'ayi, tsayin daka da kaddarorin sa na wuta.
● Resin Barrier: Babban amfani da VAM shine kera ethylene vinyl barasa (EVOH), wanda ake amfani dashi azaman resin shinge a cikin marufi, kwalabe na filastik, da tankunan mai, da kuma a cikin injiniyoyin injiniya.Barrier resins robobi ne da ake amfani da su a cikin marufin abinci don taimakawa hana iskar gas, tururi ko shigar ruwa da kuma taimakawa abinci sabo.
Tankin bakin teku na VAM wanda ke kan Jiangyin, Nanjing da Jingjiang fiye da 10000cbms. Dogaro da su, ya kafa tankunan bakin teku don yin aiki tare da abokan haɗin gwiwa na duniya kuma suna ba da mafi kyawun sabis ga abokan cinikinta na duniya.
