Khoom npe:Roj Hmab Accelerator DBTU
Lub npe tshuaj:N,N'-Dibutyl thiourea
Molecular Formula: C9H20N2S
Molecular Structure:
Molecular Luj:188.25
CAS Nr.:109-46-6
Roj hmab accelerator DBTU yog siv los ua vulcanizing tus neeg sawv cev rau cov roj hmab ntuj, butyl roj hmab, styrene -butadiene roj hmab, thiab chloroprene roj hmab. Nws tuaj yeem ua kom qhov qis -kub vulcanization txheej txheem ntawm chloroprene roj hmab thiab tseem muaj kev ua haujlwm ntawm kev tiv thaiv ozone. Cov khoom siv lub cev ntawm cov khoom siv yog ruaj khov thiab haum rau cov xov hlau, cov khoom lag luam, thiab cov khoom siv daim txhuam cev.
Cov tshuaj no yog tau los ntawm reacting n-butylamine nrog carbon disulfide ntawm 30℃thiab ces cua sov thiab decomposing. Nws yuav tsum tau muab cia rau hauv qhov chaw txias thiab qhov cua thiab cais los ntawm oxidants. MSDS qhia tias nws qhov mob toxicity (qhov ncauj) yog nyob rau theem 4, cov tawv nqaij rhiab heev yog nyob rau theem 1, thiab cov cim kev phom sij suav nrog R20/21/22 thiab R22.

Cov khoom
Dawb hmoov. Qhov ceev yog 1.32. Ib me ntsis iab, flammability, yuav luag tsis muaj tshuaj lom. Soluble nyob rau hauv cawv, diethyl ether, acetone, cyclohexanone, tetrohydrofuran, ib nrab soluble nyob rau hauv tag nrho cov PVC plasticizers, insoluble nyob rau hauv dej thiab CS2 soluble nyob rau hauv alkali daws thiab nag los ntawm acid daws.
Daim ntawv thov
Nruab nrab- ceev vulcanization accelerator. Synergises nrog sulfur pub rau boost vulcanization thaum siv NR thiab SBR. Xav tau zinc oxide kom zoo. Siv raws li theem nrab accelerator hauv CR vulcanization thiab EPDR vulcanization system. Siv rau hauv cov khoom latex, cables thiab cov khoom lag luam dav dav. Nws yog qhov tseem ceeb ntawm qhov kub thiab txias yog 80oC, yog li nws tuaj yeem siv los ua cov khoom siv raw rau cov tshuaj thiab cov tshuaj zas xim thiab cov tshuaj reagent rau Os thiab Rh.
Ntim
25kg yas woven hnab, ntawv nrog yas zaj duab xis hnab.
Cia
Cov khoom yuav tsum tau muab cia rau hauv qhov chaw qhuav thiab txias nrog qhov cua zoo, tsis txhob raug cov khoom ntim rau hauv tshav ntuj ncaj qha. Lub sijhawm siv tau yog 1 xyoos.
