Styrene ndi ntchito

Kodi styrene ndi chiyani

Styrene ndi chinthu chofunikira kwambiri pakupanga mankhwala, mankhwala ake ndi C8H8, amatha kuyaka, mankhwala owopsa, ochokera ku benzene koyera ndi kaphatikizidwe ka ethylene.Amagwiritsidwa ntchito kwambiri popanga thovu la polystyrene (EPS), polystyrene (PS), ABS ndi ma resins ena opangira ndi mphira wa styrene butadiene (SBR), SBS elastomer, zinthu zakumunsi zomwe zimagwiritsidwa ntchito kwambiri pomanga nyumba, kupanga magalimoto, zida zapakhomo, kupanga zidole, nsalu, mapepala, kunyamula nsapato ndi mafakitale ena.Kuphatikiza apo, itha kugwiritsidwanso ntchito ngati mankhwala, mankhwala ophera tizilombo, utoto, ma mineral intermediates, ali ndi ntchito zosiyanasiyana.Zomwe zimapangidwa ndi styrene ndizochokera kuchinayi KWAKULUKULU KWA Ethylene pambuyo pa polyethylene, ethylene oxide ndi vinyl chloride, ndipo kupanga styrene resins ndi yachiwiri kwa polyethylene (PE) ndi polyvinyl chloride (PVC).

1. Industrial Chain

Makhalidwe amakampani opanga ma styrene atha kufotokozedwa mwachidule ngati "mafuta okhala ndi mafuta apamwamba ndi malasha, mphira wotsika" - unyolo wamakampani amafuta amafuta apamwamba komanso unyolo wamakampani amafuta a malasha, utomoni wotsikirapo komanso mafakitale opangira mphira.

2.Gwiritsani ntchito

Kumtunda kwa styrene wa ethylene ndi benzene yoyera, kumunsi kwa styrene, EPS foam polystyrene, acrylonitrile - butadiene - styrene terpolymer, SBR/SBL styrene butadiene rabara, styrene latex ngati dispersant kunsi kwa mtsinje.EPS, ABS ndi PS ndizofunikira kwambiri kumunsi kwa styrene, zomwe zimawerengera zoposa 70%.Kuphatikiza pa gawo ili la kutsika kwa mtsinje, styrene imagwiritsidwanso ntchito muzamankhwala, utoto, mankhwala ophera tizilombo, kukonza mchere ndi mafakitale ena.

EPS foamed polystyrene imapangidwa kuchokera ku styrene ndi zinthu zowonjezera zotulutsa thovu, imakhala ndi kachulukidwe kakang'ono, kutsika kwamafuta otsika, kuyamwa kwamadzi otsika, kugwedezeka kwamphamvu, kutchinjiriza kutentha, kutchinjiriza kwamawu, umboni wa chinyezi, anti-vibration, dielectric performance ndikudikirira bwino. kuti apindule, amagwiritsidwa ntchito kwambiri pomanga zida zomangira, zida zamagetsi / zida zamaofesi zopangira zida zomangira ndi kapu / mabokosi akumwa kamodzi, ndi zina zambiri.

PS polystyrene imagwiritsidwa ntchito kwambiri m'makampani opepuka, makamaka pakukongoletsa kwatsiku ndi tsiku, zowonetsa zowunikira komanso kuyika zinthu.Kuphatikiza apo, polystyrene ndi chinthu chabwino kwambiri chotchinjiriza pamagetsi, kotero itha kugwiritsidwanso ntchito popanga zipolopolo za zida zosiyanasiyana, zida za zida ndi media capacitive.

Utoto wa ABS umapangidwa ndi styrene, acrylonitrile, butadiene terpolymer, umalimbana kwambiri ndi mphamvu, kukana kwamankhwala ndi mphamvu zamagetsi, ndi chipolopolo chapamwamba kwambiri, chomwe chimagwiritsidwa ntchito kwambiri pazida zam'nyumba / zida zamaofesi ndi zida, dashboard yamagalimoto / chitseko / chotchingira.
