styrene rau SBS
styrene rau SBS,
Styrene rau Styrene Butadiene Styrene,
styrene-butadiene-styrene (SBS) yog ib hom thermoplastic elastomer uas muaj qhov elasticity zoo ib yam nrog cov roj hmab hauv qhov kub thiab txias, thiab tuaj yeem yaj kom ntws mus rau qhov kub siab zoo li cov yas, hu ua cov khoom yas.Yog li, SBS hloov asphalt yog qhov tsis muaj kuab paug thaum raug cua sov los yog tsis yooj yim thaum txias;ntawm zoo plasticity thiab khoom ntawm aging kuj.Thiab SBS tau hloov kho asphalt tam sim no yog qhov ua tiav zoo tshaj plaws thiab siv dav siv hloov kho.Tus nqi ntawm SBS ntxiv rau hauv asphalt yog feem ntau ntawm 5% ~ 10%.SBS feem ntau yog siv los ua tsis tau tsuas yog waterproof membranes tab sis kuj sealing khoom thiab waterproof xim.
