Soo bandhigidda badeecada iyo sifooyinka
Styrene, waa isku-dhis dabiici ah, qaacidada kiimikada waa C8H8, elektaroonada vinyl-ka iyo giraanta benzene ee isku dhafan, aan ku milmin biyaha, ku milmi kara ethanol, ether iyo dareere kale oo dabiici ah, waa monomer muhiim ah oo ka kooban resin synthetic ah, resin is-weydaarsiga ion iyo caag macmal ah.
isticmaal
Isticmaalka ugu muhiimsan waa monomer caag ah iyo caag ah oo isku-dhafan, oo loo isticmaalo in lagu soo saaro caagga styrene butadiene, polystyrene, iyo xumbo polystyrene; Waxaa sidoo kale loo isticmaalaa in lagu koobiyeeyo monomers kale si loo sameeyo balaastikada injineernimada ee isticmaalka kala duwan. Sida acrylonitrile, butadiene copolymer ABS resin, oo si weyn loogu isticmaalo qalabka guryaha iyo warshadaha kala duwan; SAN copolymerized oo leh acrylonitrile waa resin leh iska caabin saameyn iyo midab dhalaalaya. SBS copolymerized oo leh butadiene waa nooc ka mid ah caagga thermoplastic, oo si weyn loogu isticmaalo polyvinyl chloride, wax ka beddelka polypropylene.
Styrene waxaa inta badan loo isticmaalaa soo saarista resin taxanaha styrene iyo cinjirka styrene BUTADIene, sidoo kale waa mid ka mid ah walxaha ceeriin ee loogu talagalay soo saarista resin-ka is-weydaarsiga ion iyo daawada, marka lagu daro, styrene waxaa sidoo kale loo isticmaali karaa daawooyinka, rinjiga, sunta cayayaanka iyo farsamaynta macdanta iyo warshadaha kale. 3. Isticmaalka:
Si loo helo waxqabadka ugu wanaagsan, waxaa lagu talinayaa in lagu daro ka dib marka la qaso. Cadadka biyaha la isticmaalo wuxuu inta badan ku xiran yahay nidaamka codsiga. Isticmaaluhu waa inuu go'aamiyaa cadadka ugu fiican isagoo tijaabinaya ka hor inta uusan isticmaalin.
xirmada iyo gaadiidka
B. Badeecadan waxaa loo isticmaali karaa, 200KG, 1000KG foosto balaastig ah.
C. Ku kaydi meel qabow, qalalan oo hawo leh gudaha. Weelasha waa in si adag loo xidhaa ka dib isticmaal kasta ka hor inta aan la isticmaalin.
D. Badeecadan waa in si fiican loo xiraa inta lagu jiro rarista si looga hortago qoyaanka, alkali iyo aashitada xooggan, roobka iyo wasakhda kale ee isku dhafan.
