Siv cov cwj pwm: Qhov sib txig ntawm qhov khoom no yog 1.32-1.38, soluble ethanol, acetone, benzene, dichloroethane, tsis muaj dej nyob hauv thiab dej cawv hydrocarbons. Siv raws li lub roj hmab thiab hluavtaws roj hmab vulcanizing tus neeg sawv cev. Txij li thaum cov dej qab ntsev tuaj yeem tso tawm hauv qhov ntsuas kub ntawm vulcanization, cov mis sulfur yog ib tus neeg sawv cev ntxhua khaub ncaws. Cov dej qab ntsev zoo tshaj plaws yog txog 27%. Lub lag luam yog kev nyab xeeb, txawm tias nws muaj chav nrog alkaline rauv dub, yog tsis muaj scorch. Tus nqi ntawm qhov siv lo lus swb qeeb qeeb, thiab nws tuaj yeem siv nrog thiazole, thiuram thiab dithiocarbamate los ua kom tus ntxhua qhov ntau dua. Nws ua haujlwm zoo dua nrog ib qho me me ntawm leej faj. Salicylic acid kuj tuaj yeem txhawb lub zuj zus ntawm cov khoom no thiab leeb cov nqi ntawm vulcanization, tab sis nws yuav txo tau lub cev nqaij daim tawv. Cov khoom no tsis siv tshuaj tsuag, tsis ua pa, tsis hloov xim, thiab yooj yim los faib. Vulcanized roj hmab yog kub resistant, resistant rau laus thiab muaj me me deformation. Kuj tseem siv tau ua tus txhawb nqa. Feem ntau siv cov khoom siv ntawm cov log tsheb, butyl puab leeg, txhua yam khoom siv hluav taws xob-resistant roj hmab, cov khoom tshwj xeeb tshaj li qub thiab cov khoom siv roj teeb xim.
Kev sib tov zoo tshaj plaws ntawm DTDM tua system yog raws li nram no:

Lus Cim: Qhov ntsuas kub ntawm cov khoom no yog 140 ° C, thiab qhov txo qis ntawm combustion concentration yog 20.5 g / m3. Muaj kev kub ntxhov thaum muaj kev ziab. Cov hmoov sib tov uas yog hmoov sib tov yog qhov muaj feem yuav tawg. Nws yog tshuaj lom me ntsis. Khaws nyob rau hauv qhov chaw tsaus kom tiv thaiv tsis txhob lwj. Tsis txhob kov cov tawv nqaij thiab qhov muag.
