wehewehe:ʻO Vinyl acetate (VAC), i kapa ʻia ʻo vinyl acetate, he mea koʻikoʻi koʻikoʻi.Ma o ka polymerization a i ʻole copolymerization me nā monomers ʻē aʻe, hiki i ka vinyl acetate ke hana i nā huahana e like me ka polyvinyl alcohol (PVA), vinyl acetate ethylene copolymer (EVA), polyvinyl acetate (PVAc), vinyl acetate vinyl chloride copolymer (EVC), a pēlā aku.He nui ka hoʻohana ʻana o kēia mau huahana, hoʻohana mau ʻia i loko o nā mea hoʻopili, pepa a i ʻole nā ​​mea hoʻonui lole, nā pena, nā inika, ka hana ʻili, nā emulsifiers, nā kiʻiʻoniʻoni wai, nā mea hoʻomaikaʻi lepo a pēlā aku.

 

Nā hiʻohiʻona:ʻeleu a hiki ke puhi ʻia

 

Noi:

1. ʻO Vinyl acetate ka mea waiwai nui no ka hana ʻana i ka vinylon fiber synthetic.

2. Hoʻopili ʻia ʻo Vinyl acetate iā ia iho a i ʻole copolymerized me nā sub-monomers no ka loaʻa ʻana o ka polyvinyl alcohol, EVA, EVC, vinyl acetate-acrylonitrile fibers, vinyl acetate-acrylate copolymers, ʻo ia mau mea āpau he hoʻohana koʻikoʻi ʻoihana a hoʻohana nui ʻia.Hoʻohana ʻia ʻo ia ma ke ʻano he mea hoʻopaʻa, ka uhi ʻana i nā mea Chemicalbook, ka nui o ka lole a me ka mea hoʻopau, ka mea hoʻoikaika pepa, a no ka hana ʻana i ke aniani palekana, etc.

3. Hoʻopili ka Vinyl acetate me ka ethanol a me ka bromine e loaʻa ai ka waena o ka lāʻau Methionazole - bromoacetaldehyde diethyl acetal.

4. Hoʻohana ʻia ia no ka resin fiber synthesis, a hoʻohana ʻia hoʻi e like me ka waena a me ka mea hoʻopaʻa o ka aila ninini wahi depressant a me ka mānoanoa.

 

Nā ʻōlelo kuhikuhi maʻamau:Ke wela a ma lalo paha o ka hana a nā fiber optical a i ʻole peroxides, hiki i ka waiwai ke polymerization, e waiho ana i kahi ahi a pahū.Hoʻopaʻa ikaika me nā mea oxidants ikaika

 

Pūʻolo:190kg / pahu, a i ʻole koi e like me ka mea kūʻai aku.

 

Ka lawe ʻana a me ka mālama ʻana:

E pale i ka ua a me ka wela kiʻekiʻe i ka lawe ʻana,

E mālama i nā huahana ma kahi anuanu, malu a me ka ea, e mamao loa mai ke ahi.

Pono ka mahana mālama ma lalo o 35 ℃.
