Vinyl acetate(VAM)

Whakaahuatanga:Ko te Vinyl acetate (VAC), e mohiotia ana ko te vinyl acetate, he matū matū tino nui.Na roto i te polymerization whaiaro, te copolymerization ranei me etahi atu monomers, ka taea e te vinyl acetate te whakaputa hua penei i te polyvinyl alcohol (PVA), vinyl acetate ethylene copolymer (EVA), polyvinyl acetate (PVAc), vinyl acetate vinyl chloride copolymer (EVC), me etahi atu.He maha nga whakamahinga o enei hua, i te nuinga o te waa ka whakamahia i roto i te whakapiri, te pepa, te papanga papanga ranei, te peita, te waituhi, te tukatuka hiako, te whakaemi, te kiriata wairewa, te whakapai i te oneone me era atu.

Āhuatanga:Hohe me te mura

Taupānga:

1. Ko te Vinyl acetate te rauemi mata matua mo te hanga o te vinylon muka waihanga.

2. Ko te Vinyl acetate he polymerized na ia ano, he copolymerized ranei me nga sub-monomers ki te whiwhi i te waipiro polyvinyl, EVA, EVC, vinyl acetate-acrylonitrile fibers, vinyl acetate-acrylate copolymers, he mea nui nga whakamahinga ahumahi me te whakamahi whanui.Ka whakamahia hei here, hei whakakikorua i nga rauemi Chemicalbook, te rahinga kakano me te kaihoko whakaoti, te kaihoko whakakaha pepa, me te hanga karaihe haumaru, aha atu.

3. Ka tauhohe te Vinyl acetate ki te ethanol me te bromine ki te whiwhi i te takawaenga o te tarukino Methionazole – bromoacetaldehyde diethyl acetal.

4. Kei te whakamahia mo te whakahiato muka kapia, ka whakamahia ano hoki hei takawaenga me te here o te hinu ringihanga ira me te whakapouri.

Tiwhi whānui:Ina whakamahana, i raro ranei i te mahi a te muka whatu, te peroxide ranei, ka ngawari te matū ki te polymerization, ka puta he ahi me te pahūtanga.He kaha te tauhohenga me nga waiora kaha

Mōkī:190kg/drum, ranei whakaritenga rite Kiritaki.

Te kawe me te rokiroki:

A ape i te ua whiti me te wera nui i roto i nga waka,

Whakaorangia nga hua i roto i nga waahi makariri, marumaru me te hau, kia matara atu i te ahi.

Ko te pāmahana rokiroki kia raro iho i te 35 ℃.
