Nws yog ib hom diacyl organic peroxide, uas yog ib tug zoo vulcanizing tus neeg saib xyuas rau silicone roj hmab, nrog cov khoom siab zog thiab zoo pob tshab. Qhov kev nyab xeeb kev kho kub yog 75 ℃, vulcanization kub yog 90 ℃, thiab pom zoo npaum li cas yog 1.1-2.3%.
Cov txheej txheem ntim khoom yog qhov hnyav ntawm 20 kg fiber ntau lub raj, ntim hnab yas sab hauv. Nws tseem tuaj yeem ntim tau raws li qhov tshwj xeeb xav tau los ntawm tus neeg siv.
Class D khoom organic peroxides, khoom faib: 5.2, United Nations tus naj npawb: 3106, chav kawm II txaus ntshai khoom ntim.
Khaws lub ntim kaw thiab nyob rau hauv qhov cua zoo, * cia kub ntawm 30 ℃, zam thiab txo cov neeg ua hauj lwm xws li amines, acid, alkali, hnyav hlau compounds (promoters thiab hlau soaps), thiab txwv tsis pub ntim thiab siv nyob rau hauv lub warehouse.
Bnyob rau hauv stability: Kev khaws cia raws li cov kev mob tshwm sim los ntawm cov chaw tsim khoom, cov khoom lag luam tuaj yeem lav lub Hoobkas cov txheej txheem hauv peb lub hlis.
Main decomposition khoom:CO2,1,3-dichlorobenzene, 2,4-dichlorobenzoic acid, kab ntau npaum li cas ntawm ob 2,4-dichlorobenzene, thiab lwm yam.
1. Nyob deb ntawm qhov hluav taws kub, qhib hluav taws thiab qhov chaw kub.
2. Tsis txhob tiv tauj nrog cov tshuaj txo qis (xws li amines), cov kua qaub, cov hauv paus, thiab cov khoom siv hlau hnyav (xws li cov neeg txhawb nqa, cov xab npum hlau, thiab lwm yam)
3. Thov xa mus rau daim ntawv qhia kev nyab xeeb (MSDS) ntawm cov khoom no.
Fyog extinguishing agent: Cov hluav taws me me yuav tsum tau muab tua nrog cov hmoov qhuav qhuav lossis cov pa roj carbon dioxide tua hluav taws, thiab txau nrog dej ntau kom tiv thaiv kom tsis txhob rov ua hluav taws. Qhov hluav taws kub yuav tsum tau txau nrog dej ntau kom deb ntawm qhov chaw nyab xeeb.
