Vinyl Acetate Monomer (Sinopec VAM)
A na-ejikarị Vinyl acetate ma ọ bụ vinyl acetate monomer (VAM) mee ihe dị ka monomer na mmepụta nke kemịkalụ ndị ọzọ ejiri na ngwa ụlọ ọrụ dị iche iche na ndị ahịa.
Kedu ihe bụ monomer?
A monomer bụ molekul nwere ike jikọta ya na ụmụ irighiri ihe ndị ọzọ yiri ya ka ọ bụrụ polymer.
A na-eji polymers dabeere na VAM, gụnyere vinyl chloride-vinyl acetate copolymer, polyvinyl acetate (PVA) na mmanya polyvinyl (PVOH), na ngwa dị iche iche.
Mgbe a na-eji VAM eme polymers, vinyl acetate a na-eji na-emepụta ha na-ericha kpamkpam, nke pụtara na ọ bụ naanị ihe fọdụrụnụ ma ọ bụrụ na ọ bụla nwere ike ikpughe VAM n'onwe ya na ngwaahịa ndị a.
● Adhesives na Glues: PVA nwere ihe eji eme ihe dị iche iche, gụnyere akwụkwọ, osisi, ihe nkiri plastik na ọla, ọ bụkwa isi ihe dị na gluu osisi, gluu na-acha ọcha, gluu nke ọkwá nkà na ụlọ akwụkwọ.A na-eji PVOH eme ihe maka ihe nkiri nkwakọ ngwaahịa nrapado;ọ na-agbaze mmiri ma na-anọgide na-agbanwe ka ọ na-eme agadi.
● Agba: A na-eji polymers dabeere na VAM na-emepụta ọtụtụ agba latex dị n'ime dị ka ihe na-eme ka adhesion nke ihe niile na-egbuke egbuke na njedebe.
● Akpụkpọ anụ: A na-eji PVOH eme ihe n'ichepụta textile maka nha nke warp, bụ usoro a na-eji ihe nkiri na-echebe akwa kpuchie akwa iji belata nkwụsịtụ mgbe a na-akpa ákwà.
● Mkpuchi: A na-eji PVOH eme ihe na mkpuchi foto.A na-ejikwa ya n'ichepụta polyvinyl butyral (PVB), resin nke nwere nrapado siri ike, ihe doro anya na ihe siri ike.A na-ejikarị PVB eme ihe na iko laminated maka ụgbọ ala na ụlọ azụmahịa;ọ na-enye interlayer nchebe na nke na-enweghị atụ nke jikọtara n'etiti pane abụọ nke iko.Enwere ike iji ya na mkpuchi na inks.A na-ejikwa ihe ndị sitere na VAM dị ka ihe mkpuchi na ihe nkiri plastik maka nkwakọ nri.
● Mgbanwe Starch Food: Enwere ike iji VAM mee ihe dị na ihe ndozi nri starch.A na-ejikarị starch nri emezigharị dị ka ihe mgbakwunye nri maka otu ihe ahụ a na-eji starch eme ihe: iji sie ike, kwado ma ọ bụ emulsify ngwaahịa nri dị ka ofe, sauces na gravy.
● Ihe ndị na-eme ka mmiri sie ike: A na-eji PVOH eme ihe dị ka ihe na-eme ka mmiri sie ike n'ụfọdụ mmiri mmiri.Enwere ike ịgbakwunye ihe ndị na-eme ka mmiri dị arọ na ụfọdụ mmiri mmiri iji nyere aka gwọọ dysphagia, ma ọ bụ ihe isi ike ilo, na iji nyere ọdịnaya nke ihe ọṅụṅụ dị nro aka ịnọgide na-ekesa nke ọma.
● Ihe mkpuchi: A na-eri VAM n'ichepụta ethylene vinyl acetate (EVA), nke a na-eji na waya na mkpuchi eriri n'ihi mgbanwe ya, ịdịte aka na ihe ndị na-ere ọkụ.
● Resin mgbochi: Ojiji VAM na-eto eto bụ imepụta mmanya ethylene vinyl (EVOH), nke a na-eji dị ka resin mgbochi n'ime nkwakọ ngwaahịa nri, karama rọba, na tankị mmanụ, nakwa n'ime polymer engineering.Resins mgbochi bụ plastik eji na nkwakọ nri iji nyere aka gbochie gas, vepo ma ọ bụ mmiri mmiri banye n'ime ya ma nyere aka mee ka nri dị ọhụrụ.
VAM n'ikpere mmiri tank nke dị na Jiangyin, Nanjing na Jingjiang karịa 10000cbms. Na-adabere na nke, guzosie ike n'ikpere mmiri tankị na-arụkọ ọrụ karịa ya na mba mmekọ na-enye kasị mma ọrụ ya zuru ụwa ọnụ ahịa.
