Soo bandhigida alaabta iyo sifooyinka
Styrene, waa unug dabiici ah, qaacidada kiimikada waa C8H8, elektarooniga vinyl iyo giraanta benzene conjugate, aan milmayn biyaha, milanka ethanol, ether iyo dareerayaasha kale ee organic, waa monomer muhiim ah oo ah resin synthetic, resin sarrifka ion iyo caag synthetic.
isticmaal
Isticmaalka ugu muhiimsan waa sida caag synthetic ah iyo monomer caag ah, oo loo isticmaalo in lagu soo saaro caag butadiene styrene, polystyrene, xumbo polystyrene;Waxa kale oo loo istcimaalay in lagu daro monomers kale si loogu sameeyo balaastikada injineernimada ee isticmaalyo kala duwan.Sida acrylonitrile, butadiene copolymer ABS resin, oo si weyn loogu isticmaalo noocyada kala duwan ee qalabka guriga iyo warshadaha;SAN copolymerized with acrylonitrile waa resin leh saameyn iska caabin ah iyo midab dhalaalaya.SBS copolymerized with butadiene waa nooc ka mid ah caag heerkulbeeg ah, oo aad loo isticmaalo sida koloriinta polyvinyl, polypropylene modifier.
Styrene waxaa inta badan loo isticmaalaa in wax soo saarka ee taxanaha styrene iyo styrene caag BUTADIene, sidoo kale waa mid ka mid ah alaabta ceeriin ee wax soo saarka ee xabagta sarrifka ion iyo daawada, marka lagu daro, styrene waxa kale oo loo isticmaali karaa in farmashiyaha, dheeha, sunta cayayaanka iyo warshadaynta macdanta. iyo warshado kale.3. Isticmaalka:
Waxqabadka ugu fiican, waxaa lagu talinayaa in lagu daro ka dib marka la qaso.Qadarka biyaha la isticmaalo waxay inta badan ku xiran tahay nidaamka codsiga.Isticmaaluhu waa inuu go'aamiyaa qadarka ugu fiican isagoo tijaabinaya kahor isticmaalka.s.
xirmo iyo gaadiid
B. Alaabtan waxa loo isticmaali karaa ,200KG,1000KG foosto caag ah.
C. Ku kaydi meel qabow, qalalan oo hawo leh oo gudaha ah.Weelasha waa in si adag loo xidhaa ka dib isticmaal kasta ka hor intaan la isticmaalin.
D. Alaabtan waa in si fiican loo xiraa inta lagu jiro gaadiidka si looga hortago qoyaanka, alkali xooggan iyo aashitada, roobka iyo wasakhda kale ee isku darka.
