Siab ntws ABS-GF, FR siab kub ua haujlwm rau OA daim ntawv thov

ABS yog terpolymer ua los ntawm polymerizing styrene thiab acrylonitrile nyob rau hauv lub xub ntiag ntawm polybutadiene. Cov proportions yuav txawv ntawm 15% mus rau 35% acrylonitrile, 5% mus rau 30% butadiene thiab 40% mus rau 60% styrene. Qhov tshwm sim yog cov saw ntev ntawm polybutadiene crises-hla nrog luv luv ntawm poly (styrene-co-acrylonitrile). Cov pab pawg nitrile los ntawm cov saw hlau nyob sib ze, ua polar, nyiam ib leeg thiab khi cov saw hlau ua ke, ua rau ABS muaj zog dua li ntshiab polystyrene. Lub acrylonitrile kuj tseem txhawb cov tshuaj tiv thaiv, qaug zog tiv thaiv, hardness, thiab rigidity, thaum ua kom kub deflection kub. Lub styrene muab cov yas ci ci, impervious nto, nrog rau hardness, rigidity, thiab txhim kho kev yooj yim. Cov polybutadiene, ib yam khoom siv roj hmab, muab cov tawv tawv thiab ductility ntawm qhov kub thiab txias, ntawm tus nqi ntawm tshav kub tsis kam thiab rigidity. Rau feem ntau ntawm cov ntawv thov, ABS tuaj yeem siv nruab nrab ntawm −20 thiab 80 ° C (−4 thiab 176 ° F), vim nws cov khoom siv sib txawv nrog qhov kub thiab txias. Cov khoom yog tsim los ntawm roj hmab toughening, qhov twg cov khoom zoo ntawm elastomer raug faib thoob plaws hauv cov matrix nruj.
