Cov kua dej Styrene Monomer
Cov kua dej Styrene Monomer,
styrene kua, Phenyl ethylene, vinyl-benzene, CAS: 100-42-5,
Styrene yog ib tug ntshiab, tsis muaj xim oily kua nrog ib tug qab zib, aromatic tsw.Nws yog miscible nrog feem ntau cov kuab tshuaj organic thiab me ntsis soluble hauv dej.Nws yog ib qho hnyav hnyav rau hluavtaws roj hmab, cov yas muaj zog, polystyrene thiab lwm yam siab molecular hnyav polymers.
Styrene tuaj yeem ua copolymerized nrog acrylates, methacrylates, acrylonitrile, butadiene, divinylbenzene thiab maleic anhydride.Nws teb rau ntau yam kev pib nrog rau peroxides thiab lwm yam dawb radical pib, redox initiator systems thiab ionic initiators.
Synonyms: Phenyl ethylene, vinyl-benzene, styrol, cinnamene, vinyl polymer, polyvinyl resin
Kev siv ntawm Styrene
Styrene yog monomer rau zus tau tej cov homopolymers thiab copolymer, qhov zoo tshaj plaws paub ntawm uas yog polystyrene, nyob rau hauv tej khoom los yog expandable daim ntawv.
Styrene yog cov khoom siv raw hauv kev tsim cov khoom siv ntau yam uas tau siv ntau txhiab yam khoom kawg xws li CD rooj plaub, lub tub yees hauv ob sab phlu, cov thawv ntim khoom noj, cov log tsheb, cov khoom siv ua si xws li cov kaus mom caij tsheb kauj vab, cov ntaub pua plag rov qab, cov keyboards thiab vaj tse rau ib lub tsev. Muaj ntau yam khoom siv lom zem hauv tsev xws li TV, khoom siv suab thiab video thiab games consoles.Stryene-raws li cov khoom yog cov yam ntxwv ntawm lawv cov toughness thiab rwb thaiv tsev zog.Vim li ntawd lawv tau nquag siv hauv cov thawv rau kev siv kho mob xws li kev thauj mus los ntawm cov tshuaj tiv thaiv thiab cov khoom nruab nrog cev
