Vinyl acetate (VAM)

Kufotokozera:Vinyl acetate (VAC), yomwe imadziwikanso kuti vinyl acetate, ndi yofunika kwambiri pakupanga mankhwala.Kudzera polima polima kapena copolymerization ndi ma monomers ena, vinyl acetate imatha kupanga zinthu monga polyvinyl mowa (PVA), vinyl acetate ethylene copolymer (EVA), polyvinyl acetate (PVAc), vinyl acetate vinyl chloride copolymer (EVC), ndi zina zotero.Zogulitsazi zimakhala ndi ntchito zosiyanasiyana, zomwe zimagwiritsidwa ntchito pomatira, mapepala kapena zopangira nsalu, utoto, inki, kukonza zikopa, emulsifiers, mafilimu osungunuka m'madzi, owongolera nthaka ndi zina zotero.

Makhalidwe:Yogwira ndi yoyaka

Ntchito:

1. Vinyl acetate ndiye chinthu chachikulu chopangira chopangira vinylon.

2. Vinyl acetate ndi polymerized palokha kapena copolymerized ndi sub-monomers kupeza polyvinyl mowa, EVA, EVC, vinyl acetate-acrylonitrile ulusi, vinyl acetate-acrylate copolymers, onse ali ndi ntchito zofunika mafakitale ndipo amagwiritsidwa ntchito kwambiri.Amagwiritsidwa ntchito ngati binder, zokutira zomanga Chemicalbook zakuthupi, sizing za nsalu ndi kumaliza, wothandizira mapepala, komanso kupanga galasi lachitetezo, etc.

3. Vinyl acetate imakhudzidwa ndi ethanol ndi bromine kuti ipeze mankhwala apakati a Methionazole - bromoacetaldehyde diethyl acetal.

4. Amagwiritsidwa ntchito popanga utomoni wa fiber synthesis, komanso amagwiritsidwa ntchito ngati wapakatikati komanso womangira mafuta othira tsinde la depressant ndi thickener.

Malangizo onse:Pamene kutentha kapena pansi zochita za ulusi kuwala kapena peroxides, chinthu sachedwa polymerization, kuchititsa ngozi moto ndi kuphulika.Imachita mwankhanza ndi zotulutsa zolimba

Phukusi:190kg / ng'oma, kapena chofunikira ngati Makasitomala.

Mayendedwe ndi kusungirako:

Pewani mvula ndi kutentha kwambiri pamayendedwe,

Sungani zinthuzo pamalo ozizira, amthunzi komanso mpweya wabwino, khalani kutali ndi moto.

Kutentha kosungirako kuyenera kukhala kosachepera 35 ℃.
