Xwm: dawb crystalline hmoov, iab iab. Kev daws teeb meem hauv alkali, insoluble hauv dej txias, ethanol, acetone, insoluble hauv roj thiab toluene. Kev sib xyaw, qhov sib txawv ntawm qhov kub thiab txias 196 ° C, nws pib-lub qhov hluav taws kub kub 421 ° C. Kev sib xyaw nrog huab cua yog qhov muaj qhov txaus ntshai. Muaj mob pesnrab. Kev khaws cia yog qhov ruaj khov, tab sis nws yog qhov zoo tshaj plaws los tso nws rau hauv qhov chaw qhuav ntawm qhov kub tsawg.

Muaj nuj nqi: ntau yam ntawm neoprene, chlorosulfonated polyethylene roj hmab, chloroether roj hmab, acrylate roj hmab accelerator. Nws yog qhov tsim rau cov hlau oxide vulcanization, tshwj xeeb tshaj yog magnesium oxide thiab zinc oxide raws li cov neeg sawv cev vulcanizing. Lub lag luam zoo, tsis yooj yim hlawv. Nyob rau ntawm ib txwm ntsuas kub ntawm vulcanization, qhov ntsuas vulcanization tau sai dua. Nrog rau qhov nce ntawm cov tshuaj ntau dua, qhov vulcanization tus nqi tseem tuaj yeem ua tau zoo tuaj, tab sis qhov kev ua haujlwm tiv thaiv tsis zoo kuj poob qis. Kev siv lub nrawm DM tuaj yeem txhim kho qhov scorch tsis kam. Siab, qis dua deformation, zoo elasticity thiab kub tsis kam. Sulphur tsis muaj qhov cuam tshuam ncaj qha rau lub vulcanization, tab sis muaj qhov nyiam kom qis qis crystallization, ua kom muaj kev ntxhov siab ntau dua qub, thiab ua kom lub zog tiv thaiv kev laus. Cov khoom no tshwj xeeb tshaj yog tsim rau W hom thiab lub hom phiaj dav dav neoprene. Rau W-type chloroprene roj hmab, dej-resistant roj hmab tuaj yeem tsim tau los ntawm kev siv cov hlau lead oxide lossis lead sulphide ua tus neeg sawv cev vulcanizing, tab sis cia lub teeb meem tsis zoo; salicylic acid muaj nws cov haujlwm ua kom muaj zog thiab tuaj yeem txhim kho qhov teeb tsa ntawm tus neeg sawv cev vulcanizing. Kev ntxhov siab; stearic acid muaj qhov ua haujlwm ntawm rov ua kom vulcanization. Thaum siv rau hauv cov hom phiaj dav dav GN hom neoprene, nws muaj kev ua haujlwm zoo dua qub thiab ua kom ruaj ntseg. Nws yooj yim rau kev tawg tawm hauv cov roj hmab, tsis muaj kuab paug, tsis muaj kev tshem tawm.
