Tshuaj Tshuaj Muaj Zog:

Styrene yog kua ntawm chav tsev kub, tsis muaj xim liab, styrees yog insoluble hauv dej, yog tias ntawm 25 degrees Celsius, Styrees solubility tsuas yog 0.066%. Styrene tuaj yeem sib xyaw nrog EThere, methyl ferment, carbon ferment, acetone, benzene, benzene, betra-ironic carbon hauv ib qho kev faib ua feem. Styrene yog qhov zoo siv kuab rau ntuj roj hmab, hluavtaws roj hmab thiab ntau cov organic sib xyaw. Styrene yog tshuaj lom thiab tuaj yeem ua rau lom yog tib neeg lub cev nqus tau ntau dhau vapor. Kev tso cai concentration ntawm styrene hauv huab cua yog 0.1mg / l. Styrene vapor thiab huab cua yuav tsim kev sib xyaw tawg.

Daim Ntawv Thov:

Styrene yog ib qho tseem ceeb monomer ntawm cov roj hmab hluavtaws hluavtaws, cov nplaum thiab cov plastics. [3,4,5] Nws yog siv rau kev sib txuas ntawm cov roj hmab butadiene nqa roj hmab thiab roj hmab polystyrene cob, polyester iav fiber ntau ntxiv rau cov plastics thiab txheej. Nws yog siv rau kev npaj polystyrene, ion sib pauv resin, thiab ua npuas ncauj polystyrene. Nws kuj tseem siv rau cov copolymerization nrog lwm cov monomers los ua ntau yam kev txhim kho tshuab, xws li copolymerization ntawm acrylonitrile thiab butadiene los tsim cov khoom siv ua lwm yam hauv tsev neeg thiab kev lag luam. Copolymerization nrog acrylonitrile, tau san yog ib tug cob nrog kev poob siab tsis kam thiab ci xim. Cov SBS ua los ntawm Butadiene nrog Butadiene yog cov roj hmab thermoplastic, uas yog dav siv ua polyvinyl chloride thiab Acrylic hloov kho. SBS thiab SIS Thermoplastic elastomers yog ua nrog butadiene thiab isoprene copolymerization, thiab ua tus ntoo khaubligees ntawm PVC, polypropylene, thiab polyesterated polyester.
Syrene yog siv los ua cov monomer nyuaj rau kev tsim cov khoom siv Acrylic Emulsion thiab cov kuab tshuaj rhiab cov nplaum. Emulsion nplaum thiab cov xim pleev xim tuaj yeem npaj los ntawm Copolymerization nrog Vinyl acetate thiab acrylic ester. Styrene yog ib qho ntawm feem ntau siv vinyl monomers hauv thaj chaw scientific, siv hauv ntau cov ntaub ntawv hloov kho thiab sib xyaw. [6]
Ib qho ntxiv, ib qho me me ntawm cov styrene kuj tau siv ua naj hoom thiab lwm yam nruab nrab. Los ntawm chloromethylation ntawm styrene, cinnamyl chloride yog siv los ua cov tshuaj tiv thaiv kev mob siab, thiab cov extrichholinive thiab anticholinergic qub tshuaj nyob hauv plab hloov. Nws tuaj yeem siv tau los ua ke los synthesize zas xim nruab nrab, tshuaj tua kab mob emulsifiers, thiab styrees phosphonic acids thiab tooj liab plhaw cov neeg sawv cev.
