Cov qauv yog massed los ntawm zeb, dhau 250 ± 5g ntawm cov qauv ntawm cov yob nrog yob kub ntawm 50 ± 5℃thiab qhov kev ncua deb ntawm yob ntawm 1.4 ± 0.1 hli, tag nrho kaum dhau.
Daim ntawv thov
Nitrile roj hmab 3345 yog nruab nrab -acrylonitrile, qis-Mooney, ceev- kho hom nitrile roj hmab. Nws yog tus cwj pwm los ntawm kev ua haujlwm zoo heev, ua haujlwm yooj yim, thiab tsis muaj pwm paug. Nws yog ntau yam roj hmab raw khoom resistant rau roj. Nws yog tsim los ntawm qhov qis -kub emulsion polymerization ntawm butadiene thiab acrylonitrile. Cov roj hmab thaiv yog lub teeb xim av xim, nrog cov xim ntshiab thiab zoo nkauj, thiab tuaj nrog cov tsis muaj - pa phem antioxidant uas tiv thaiv tsis muaj xim thiab kev laus. Nws yog tsim rau ntau yam txheej txheem xws li extrusion, molding, thiab foaming, thiab yog dav siv nyob rau hauv cov khoom xws li roj kav, roj foob, gaskets, automotive qhov chaw, roj-cov khau khau khau, thiab lwm yam.
Khoom zoo
Mullen viscosity tsawg, uas ua rau muaj qhov zoo heev ntawm cov roj hmab sib xyaw. Lub extrusion nto yog du yam tsis muaj cov qauv, thiab cov txheej txheem molding tsis tshua muaj rau cov khoom tsis txaus thiab cua npuas. Cov txheej txheem vulcanization yog ceev, nrog kev ua haujlwm siab, ua rau nws haum rau cov kab ntau lawm. Nws muaj qhov ua tau zoo ruaj khov hauv kev tiv thaiv cov roj ntxhia thiab cov roj hydraulic, nrog kev sib npaug rov qab thiab hnav tsis kam. Cov mis muaj zog sib xws thiab tuaj yeem sib xyaw thiab hloov nrog PVC. Nws ua rau tsis muaj pwm tsis zoo, cov khoom zoo li huv si, nws tsis yooj yim rau frosting los yog xim hloov, thiab muaj cov nqi zoo heev -effectiveness.
