Styren iyo codsiga

Waa maxay styrene

Styrene waa walxo kiimiko ah oo muhiim ah oo ceeriin ah, qaacideeda kiimikaad waa C8H8, kiimiko guban kara, khatar ah, oo ka timid benzene saafi ah iyo isku dhafka ethylene.Waxaa inta badan loo isticmaalaa in wax soo saarka ee polystyrene xumbo (EPS), polystyrene (PS), ABS iyo resins kale synthetic iyo styrene butadiene caag (SBR), SBS elastomer, alaabta hoose waxaa si ballaaran loo isticmaalaa in dahaarka dhismaha, wax soo saarka baabuurta, qalabka guriga, wax soo saarka toy, dhar, warqad, baakadaha kabaha iyo warshadaha kale.Intaa waxaa dheer, waxa kale oo loo isticmaali karaa daawo ahaan, sunta cayayaanka, dheeha, dhexdhexaadiyeyaasha macdanta, waxay leedahay adeegsiyo ballaaran.Soosaarayaasha Styrene ayaa ah kuwa afraad ee ugu weeyn ethylene ka dib polyetylen, ethylene oxide iyo vinyl chloride, iyo soo saarista xabagta styrene ayaa ka xigta kaliya polyetylen (PE) iyo polyvinyl chloride (PVC).

1. Silsiladda Warshadaha

Sifooyinka silsiladda warshadaha styrene waxaa lagu soo koobi karaa sida "saliid dhalada sare iyo dhuxusha, caag hoose" - silsiladda warshadaha kiimikada batroolka ee sare iyo silsilad warshadaha kiimikada dhuxusha, xadhkaha hoose ee resin synthetic iyo warshadaha caag synthetic.

2.Isticmaal

Xagga sare ee styrene ee ethylene iyo benzene saafi ah, ka hooseeya ee styrene, EPS xumbo polystyrene, acrylonitrile - butadiene - styrene terpolymer, SBR/SBL styrene butadiene caag, styrene cinjirka sida firdhisan hoose.EPS, ABS iyo PS waa baahida ugu weyn ee isha hoose ee styrene, taasoo ka dhigan in ka badan 70%.Marka laga soo tago qaybtan baahida hoose, styrene waxa kale oo loo isticmaalaa dawooyinka, dheeha, sunta cayayaanka, warshadaynta macdanta iyo warshadaha kale.

EPS xumbada polystyrene waxaa laga sameeyaa styrene iyo walxaha lagu daro wakiilka xumbo, waxay leedahay cufnaanta yar yar, heerkulka hoose ee kulaylka, nuugista biyaha hoose, gariir naxdin leh, dahaarka kulaylka, dahaarka dhawaaqa, qoyaan-cadayga, ka hortagga gariirada, waxqabadka dielectric waa sugitaan wanaagsan faa'iido ahaan, waxaa inta badan loo isticmaalaa in lagu dhiso alaabta dahaadhka, qalabka korontada/qalabka xafiiska baakadaha barkinta iyo koob cabitaanka hal mar/sanduuqyada, iwm.

PS polystyrene waxaa si weyn loogu isticmaalaa warshadaha iftiinka, gaar ahaan qurxinta maalinlaha ah, tilmaanta iftiinka iyo baakadaha alaabta.Intaa waxaa dheer, polystyrene waa qalab aad u fiican oo ku habboon dhinaca korantada, sidaas darteed waxaa sidoo kale loo isticmaali karaa in lagu soo saaro noocyo kala duwan oo qalab ah, qaybaha qalabka iyo warbaahinta awoodda leh.

ABS resin waxa uu ka samaysan yahay styrene, acrylonitrile, butadiene terpolymer, waxa uu leeyahay iska caabin aad u fiican, caabbinta kiimikaad iyo guryaha korontada
