Tsanangudzo:Styrene (C8H8), yakakosha mvura kemikari mbishi, imonocyclic inonhuhwirira hydrocarbon ine olefin parutivi cheni uye conjugated system ine benzene mhete.Ndiyo yakapfava uye yakakosha nhengo yeunsaturated aromatic hydrocarbons.Styrene inoshandiswa zvakanyanya seyakagadzirwa kugadzirwa kwesynthetic resins uye synthetic rubber.
Styrene imvura isina ruvara patembiricha yemumba, isinganyungudike mumvura, asi inonyungudika muzvinonyungudutsa zvinonyungudutsa sepeturu, ethanol uye ether, uye ine muchetura uye ine hwema hwakakosha.Nekuti styrene ine unsaturated double bonds uye inoumba Chemicalbook conjugated system ine benzene ring, ine simba reactivity reactivity uye iri nyore kuzvi-polymerize uye polymerize.Kazhinji, styrene yakasununguka-yakanyanya polymerized nekudziya kana catalyst.Styrene inopfuta uye inogona kugadzira misanganiswa inoputika nemhepo.

Hunhu:Kusagadzikana kwakasimba

Application:

1. Inonyanya kushandiswa seyakabikwa yepolystyrene, synthetic rabha, engineering mapurasitiki, ion exchange resin, nezvimwe.

2. Kunyanya kukosha kushandiswa ndeye monomer yekugadzira rabha uye mapurasitiki kuti abudise styrene-butadiene rabha, polystyrene, uye foamed polystyrene;inoshandiswawo kuita copolymerize nemamwe mamonomers kugadzira mapurasitiki einjiniya nekuda kwezvikonzero zvakasiyana.

3. For organic synthesis uye resin synthesis

4. Inoshandiswa kugadzira copper plating inopenya, iyo inotamba basa rekuenzanisa uye kupenya.

Package:170kg net uremu, kana chinodiwa seMutengi.

Kutakura uye kuchengetedza:

1. Nekuda kwemaitiro ayo emakemikari anoshanda, styrene inowanzochengetwa mudura inotonhorera uye ine mhepo.

2. Chengetedza kure nemoto nekupisa, uye tembiricha yekuchengetedza haifanire kudarika 25 ℃

3. Kuti udzivirire self-polymerization ye styrene, TBC polymerization inhibitor inowanzowedzerwa panguva yekuchengetedza uye kutakura.

Zvakapfuura: Stearyl methacrylate (SMA)

Zvinotevera: Tert-Butyl Acrylate (TBA)
