Styrene butadiene roj hmab
Cov khoom: cov khoom ntawm latex styrene butadiene roj hmab yog tus los ntawm nws cov khoom xyaw (butadiene rau qhov sib piv styrene), qhov kub ntawm polymerization thiab hom emulsifier. Nws cov khoom feem ntau yog hais txog rosin kua tshuaj soap rau emulsifier (5 ℃) polymerization ntawm cov txheej txheem txias, kev ua si ntawm styrene yog 23.5% ntxiv lossis rho tawm cov khoom ntawm copolymer. Sbr-1500 yog hom cawv tshaj plaws ntawm kev ua kom muaj kuab zoo txaij ntawm lub pob txha mos. Rosin acid thiab fatty acid xab npum tau siv ua emulsifiers hauv polymerization. Vulcanized roj hmab tau zoo ua haujlwm, tensile zog, rhuav lub zog thiab kev laus ua hauj. Sbr-1500 yog qhov feem ntau cov tsis siv tshuaj uas tsis yog-polluting muag styrene butadiene roj hmab. Thaum polymerized, sib xyaw soaps ntawm rosin acid thiab fatty acid yog siv raws li emulsifiers. Nws qhov kev ua tau zoo ib yam li ntawm sbr-1500 nrog lub zog tensile zoo, txav tus neeg ua haujlwm thiab kev ua haujlwm tsawg. Nws muaj qhov zoo ntawm kev nplaum zoo, txhaws tsis ua hauj lwm, workability thiab tsawg tus nqi.
