Gwiritsani ntchito SBS ngati chinthu chachikulu kuti muwone zofananira ndi mafomu awo. Gwiritsani ntchito chosakanizira wamba kuti muwonjezere gawo lina la masterbatch ku riyakitala, kutentha ndikusakaniza ndi phula la matrix osiyanasiyana pafupifupi 160 ° C, ndikupanga masterbatch kudzera munjira ya granulation.
Popeza phula losinthidwa ndi polima limafuna kugwiritsa ntchito zida zapadera monga mphero zazikulu za colloid pokonza, ndipo ma polima okha ndi omwe amagwiritsidwa ntchito kusakaniza phula losinthidwa, kwenikweni ndi losavuta kuphatikiza, ndipo palibe kulumikizana kwamankhwala pakati pa polima ndi matrix. phula. Kukhazikika kwa makina osakanikirana ndi koyipa, ndipo ukadaulo wophatikizira wa SBS ndi chofananira chofananira kuti SBS yosinthidwa phula masterbatch imathandizira kayendedwe ka viscosity flow of single SBS modifier ndikuchepetsa kutentha kwa viscosity flow zone ya masterbatch. , Kutentha kosakanikirana kumachepetsedwa kuchokera ku 180 ~ 190 ℃ mpaka 160 ℃, ndipo kugwiritsa ntchito zipangizo zamakono zosakanikirana zingathe kukumana ndi kubalalitsidwa yunifolomu ndi kusakaniza kwa polima ndi phula, potero kuchepetsa kukhwima kwa kupanga ndi kupulumutsa ndalama zopangira.
