Codsiga Alaabta
Waxaa loo isticmaalaa samaynta caagadaha, balaastikada, iyo polymers-ka.
a) Wax soo saarka: polystyrene la ballaarin karo (EPS);
b) Soo saarida polystyrene (HIPS) iyo GPPS;
c) Soo saarista isku-xireyaasha styrenic;
d) Soo saarida xabagta polyesterka ee aan dheregsanayn;
e) Soo saarista caagga styrene-butadiene;
f) Soo saarista cinjirka styrene-butadiene;
g) Wax-soo-saarka styrene isoprene co-polymers;
h) Soo saarista kala firidhsanaanta styrene ee ku salaysan polymeric;
i) Soo saarida polyols buuxa.Styrene waxaa inta badan loo isticmaalaa monomer ahaan soo saarista polymers (sida polystyrene, ama caag gaar ah iyo cinjirka)
Styrene maleic anhydride (SMA ama SMAnh) waa polymer synthetic kaas oo ka kooban styrene iyo maleic anhydride monomers.monomers-yadu waxay noqon karaan kuwo si qumman isu beddela, taas oo ka dhigaysa kobolymer beddelka ah, [1] laakiin ( random) kopolymerisation wax ka yar 50% ka kooban anhydride lab ah ayaa sidoo kale suurtagal ah.Polymerization-ka waxaa lagu sameeyay polymerization xagjirka ah, iyadoo la isticmaalayo peroxide organic ah bilawga.Astaamaha ugu muhiimsan ee SMA copolymer waa muuqaalkeeda hufan, caabbinta kulaylka sare, xasilloonida cabbirka sare, iyo falcelinta gaarka ah ee kooxaha anhydride.Muuqaalka dambe wuxuu keenaa milanka SMA ee xalalka alkaline (biyaha ku salaysan) iyo kala firdhisanaanta.
SMA waxaa lagu heli karaa noocyo kala duwan oo miisaan molecular iyo maleic anhydride (MA).Isku darka caadiga ah ee labadaas guri, SMA waxay diyaar u tahay sida granule cad oo cad oo loo isticmaali karo codsiyo kala duwan.polymers SMA oo leh miisaan kelli sare ah ayaa si weyn loogu isticmaalaa codsiyada caagagga injineernimada, sida caadiga ah saameynta la beddelay iyo kala duwanaanshaha fiber galaas ikhtiyaari ah oo buuxa.Beddel ahaan, SMA waxaa lagu dabaqaa iyadoo la adeegsanayo daahfurnaanteeda iyadoo lagu darayo agabka kale ee hufan sida PMMA ama iska caabbinta kulaylka-kor u qaadista agabyada kale ee polymers sida ABS ama PVC.Solubility ee SMA ee xalalka alkaline ka dhigaysa mid ku haboon codsiyada kala duwan ee berrinkii of size (warqad), xidheyaasha, firdhiyey iyo daahan.Falcelinta gaarka ah ee SMA waxay ka dhigaysaa wakiil ku habboon iswaafajinta polymers-ka caadiga ah (tusaale ABS/PA isku-dhafka) ama isku-xidhka.Heerkulka kala-guurka dhalada ee Styren maleic anhydride waa 130 - 160 ° C.
