Hordhac iyo astaamo
Styrene, waa xarun dabiici ah, caanobooraha kiimikada waa c8h8, elektronikada vinyl iyo benzene-ka oo biyo ah, ayaa ah monomer muhiim ah oo ah resin isku-dhafan, iontretic resin resin iyo caag isku-darka ah.
isticmaal
Isticmaalka ugu muhiimsan waa isku-dhafan caag iyo balaastig ah oo caag ah, oo loo adeegsaday soo saaridda caagga styrene Butadient, polystyrene, polystyrene, polystyrene xumbo; Waxaa sidoo kale loo isticmaalaa in lagu codolo monomleris kale si loo sameeyo balaastigga injineerrada ee adeegsiyo kaladuwan. Sida acrylonitrile, Budiniene Coveymer Absomer Absin, ayaa si weyn loogu isticmaalay qalab iyo warshado kala duwan oo guryaha ah; San Copolymaried oo leh acrylonitrile waa resin leh caabbinta saameynta leh iyo midab dhalaalaya. SBS Copolanenerized with Budadiene waa nooc ka mid ah jilbaha thermoplastic-ka, si ballaaran loo isticmaalo sida polyvinyl chloride, polypropylene-ka.
Styrene waxaa inta badan loo isticmaalaa soo saarista taxanaha STYrene ee Detain iyo Styrene Butadiene, sidoo kale waa mid ka mid ah alaabta ceyriinka ah ee wax soo saarka itring-ka iyo dawada, marka lagu daro, dheeh, cayayaanka, sunta cayayaanka iyo macdanta. iyo warshadaha kale. 3. Adeegsiga:
Waxqabadka ugu fiican, waxaa lagu talinayaa in lagu daro ka dib dilid. Caddadka biyaha loo isticmaalo waxay kuxirantahay nidaamka dalabka. Adeeggu waa inuu go'aamiyaa qaddarka ugu fiican ee tijaabada ka hor inta aan la isticmaalin.s.
xirmo iyo gaadiid
B. Alaabtan waxaa loo isticmaali karaa, 200kg, 1000kg bact balaastig ah.
C. Dukaanku wuxuu ku xirnaa meel qabow, qalalan oo hawo leh gudaha gudaha ah. Weelasha waa in si adag loo xiraa oo loo xiraa ka dib isticmaal kasta kahor isticmaalka.
D. Alaabtan waa in si fiican loo xirxiraa inta lagu jiro gaadiidka si looga hortago qoyaanka, alkali xoog leh iyo aashitada, roobka iyo ciladaha kale ee isku dhafka ah.
