Shandisa SBS sechinhu chikuru chekutarisa akakodzera anowirirana uye mafomula avo. Shandisa yakajairwa musanganisi kuti uwedzere imwe chikamu che masterbatch kune reactor, kupisa uye kusanganisa neakasiyana matrix bhitumeni panosvika 160 ° C, uye ita masterbatch kuburikidza ne granulation process.
Sezvo bhitumini yakagadziridzwa yepolymer ichida kushandiswa kwemidziyo yakakosha senge mikuru yecolloid kuti igadzirwe, uye mapolymer chete ndiwo anoshandiswa kusanganisa bhitumini yakagadziridzwa, inonyanya kusanganiswa kwemuviri, uye hapana makemikari anobatana pakati pepolymer modifier uye matrix. bhitumini. Kugadzikana kweiyo yakasanganiswa sisitimu kwakashata, uye tekinoroji yekubatanidza yeSBS uye inofananidzira inopindirana kugadzira SBS yakagadziridzwa bhitumene masterbatch inovandudza viscosity kuyerera maitiro eimwe SBS inogadzirisa uye inoderedza tembiricha yeviscosity flow zone ye masterbatch. , tembiricha yekusanganisa inodzikiswa kubva pa180 ~ 190 ℃ kusvika 160 ℃, uye kushandiswa kweyakajairwa kusanganisa midziyo inogona kusangana nekupararira kweyunifomu nekusanganiswa kwepolymer nebhitumini, nokudaro kuderedza kusimba kwekugadzira uye kuchengetedza mari yekugadzira.
Yakanatswa styrene + yakanatswa mhinduro + yakanatswa butadiene + antioxidant → polymerization → kuita musanganiswa → post-kugadzirisa, kurongedza
