Product Detail

Khoom cim npe

Nqe lus piav qhia:Styrene (C8H8), ib qho tseem ceeb kua tshuaj raw khoom, yog ib tug monocyclic aromatic hydrocarbon nrog ib tug olefin sab saw thiab ib tug conjugated system nrog ib tug benzene nplhaib.Nws yog tus tswv cuab yooj yim tshaj plaws thiab tseem ceeb tshaj plaws ntawm unsaturated aromatic hydrocarbons.Styrene yog dav siv los ua raw khoom rau zus tau tej cov hluavtaws resins thiab hluavtaws roj hmab.
Styrene yog cov kua tsis muaj xim nyob rau hauv chav tsev kub, insoluble nyob rau hauv dej, tab sis soluble nyob rau hauv cov organic solvents xws li roj av, ethanol thiab ether, thiab yog tshuaj lom thiab muaj ib tug tshwj xeeb tsw.Vim hais tias styrene muaj unsaturated ob daim ntawv cog lus thiab tsim ib Chemicalbook conjugated system nrog lub nplhaib benzene, nws muaj zog tshuaj reactivity thiab yooj yim rau nws tus kheej-polymerize thiab polymerize.Feem ntau, styrene yog dawb-radically polymerized los ntawm cua sov los yog catalyst.Styrene yog flammable thiab tuaj yeem tsim cov khoom tawg nrog cua.

Yam ntxwv:Muaj zog volatility

Daim ntawv thov:

1. Feem ntau yog siv los ua raw khoom rau polystyrene, hluavtaws roj hmab, engineering plastics, ion exchange resin, thiab lwm yam.

2. Qhov tseem ceeb tshaj plaws yog siv raws li ib tug monomer rau hluavtaws roj hmab thiab yas los tsim styrene-butadiene roj hmab, polystyrene, thiab foamed polystyrene;nws kuj yog siv los copolymerize nrog lwm cov monomers los tsim engineering plastics rau ntau lub hom phiaj.

3. Rau cov organic synthesis thiab resin synthesis

4. Nws yog siv los tsim tooj liab plating brightener, uas plays lub luag hauj lwm ntawm leveling thiab brightening

Pob:170kg net hnyav, lossis yuav tsum tau ua raws li Cov Neeg Siv Khoom.

Kev thauj mus los thiab khaws cia:

1. Vim nws cov khoom siv tshuaj lom neeg, styrene feem ntau khaws cia rau hauv qhov chaw txias thiab cua txias.

2. Khaws kom deb ntawm qhov hluav taws kub thiab qhov cua sov, thiab qhov chaw cia kub yuav tsum tsis pub tshaj 25 ℃

3. Txhawm rau tiv thaiv tus kheej-polymerization ntawm styrene, TBC polymerization inhibitor feem ntau yog ntxiv thaum khaws cia thiab thauj.

Yav dhau los: Stearyl methacrylate (SMA) hmoov

Tom ntej: Tert-Butyl Acrylate (TBA)
