U isticmaal SBS sida shayga ugu muhiimsan si aad u baarto kuwa ku habboon iyo qaababkooda. Isticmaal qasiyaha caadiga ah si aad ugu darto qayb gaar ah oo masterbatch ah reactor-ka, kulayl oo ku qas bitumen-matrix kala duwan oo ku saabsan 160 ° C, oo ka samee masterbatch iyada oo loo marayo habka granulation.
Maadaama bitumen-ka polymer-ku-beddelay ay u baahan tahay isticmaalka qalab gaar ah sida warshado waaweyn oo kolloid ah oo lagu farsameeyo, oo kaliya polymers ayaa loo isticmaalaa in lagu qaso bitumen la beddelay, inta badan waa isku-dhafka jirka oo fudud, mana jirto isku-xidhka kiimikaad ee u dhexeeya beddelka polymer-ka iyo matrixka. bitumen. Xasiloonida nidaamka isku dhafan waa mid liidata, iyo tignoolajiyada isku dhafan ee SBS iyo isbarbardhiga u dhigma si loo sameeyo SBS modified bitumen masterbatch waxay hagaajinaysaa habdhaqanka socodka viscosity ee hal beddelka SBS waxayna yaraynaysaa heerkulka aagga qulqulka viscosity ee masterbatch. , heerkulka isku dhafka ah ayaa laga dhimay 180 ~ 190 ℃ ilaa 160 ℃, iyo isticmaalka qalabka isku dhafan ee caadiga ah waxay la kulmi karaan kala firdhinta lebiska iyo isku dhafka polymer iyo bitumen, taas oo yareyneysa wax soo saarka iyo badbaadinta kharashka wax soo saarka.
Styrene la safeeyey + xal la safeeyey + butadiene la safeeyey + antioxidant → polymerization → isku darka falcelinta → habaynta ka dib, baakadaha
