Kumvetsetsa styrene-butaniene rabara (SBR): Chuma chachikulu chogwiritsidwa ntchito kwambiri pamafakitale

Rayrene-butadiene (SBR) Kodi ndi dziko lomwe limapangidwa kwambiri padziko lonse lapansi ndikupanga rabar. Copyolyrmed kuchokera ku styrene ndi bunadiene, imapereka zinthu zokwanira ndi zinthu zazikulu za zinthu zosiyanasiyana za mphira kuphatikiza matayala, mawonekedwe a nsapato, ndi hoses.

Kutengera ndi njira za polymerization, zimaphatikizidwa mu emulsion-polymenized stylrab (e-sbr) ndi solymedized styrene rabara (str-sbr). E-SBR, ndi njira yake yokhwima ndi mtengo wotsika, imagwiritsidwa ntchito kwambiri m'matayala ndi zinthu zomwe amagwiritsa ntchito. S-SBR imapereka kapangidwe kake, ndikuchepetsa mphamvu yayikulu, ndikuchepetsa kukana kukana, ndikupanga kukhala matayala obiriwira ambiri.

Ubwino wake wogwirira ntchito:

Akuluakulu abrasion, makamaka mu S-SBR;

Kukana kukalamba kwakukulu poyerekeza ndi mphira mwachilengedwe;

Kusandulika kwambiri komanso kuphatikizidwa;

Magwero ambiri okhala ndi zosaphika komanso mtengo wokhazikika.

Ntchito zoyambirira zimaphatikizapo matayala (kupondaponda ndi malo amtundu), Zisindikizo zaokha , zinthu zokongola kwambiri, malamba onyamula , ndi mawonekedwe a nsapato. Pakati pa zochitika zobiriwira zobiriwira, S-SBR imathandizira mapangidwe omwe amachepetsa mataulidwe omwe amatha kuthana ndi kuthamanga ndikuwonjezera chuma chamafuta, ndikupangitsa kuti ikhale yofunika kwambiri yamatayala atsopano.

Rayrene-butadiene (SBR) Kodi ndi dziko lomwe limapangidwa kwambiri padziko lonse lapansi ndikupanga rabar.
