Roj Hmab Accelerator DOTG Hmoov

Roj Hmab Accelerator DOTG (Di-o-tolylguanidine)

Khoom npe:Di-o-tolylguanidine
Lub npe lag luam:Roj Hmab Accelerator DOTG
Lub npe tshuaj:1,3-Di-o-tolylguanidine
Synonyms:N,N'-Di-o-tolylguanidine
CAS Nr.: 97-39-2
EC No.: 202-577-6

Accelerator DOTG provides strong activation for thiazole (MBTS, MBT, ZMBT) accelerated curing systems in NR, SBR, and NBR. It is also effective in CR with thiuram/sulfur cures. DOTG exhibits better processing safety than DPG (diphenyl guanidine). DOTG requires the use of zinc oxide to develop a good cure. Fatty acids are not required; in fact, excess fatty acids (>1phr) tuaj yeem ua rau txo qis hauv lub cev. Vulcanizates kho nrog DOTG ua rau lub xeev siab kho. Cov khoom sib xyaw siv DOTG ua tus accelerator thib ob tuaj yeem ua vulcanized los ntawm txhua txoj kev (xovxwm, chav, cua kub). Antioxidants yeej ib txwm pom zoo rau kev tiv thaiv kev laus tshaj plaws. Txawm hais tias DOTG tau txais raws li CFR 21, ntu 177.2600 "Cov Khoom Roj Hmab Npaj Rau Kev Tiv Thaiv Cov Khoom Noj Rov Qab," nws cov ntxhiab tsw thiab iab saj imparted rau ib tsab xov xwm roj hmab yuav txwv tsis pub nws siv hauv zaub mov- tuav daim ntawv thov. DOTG tseem yuav ua rau cov tshuaj dawb ua kom tsis muaj xim thaum lawv raug teeb.

Grey-dawb hmoov los yog granule nrog ib tug me ntsis iab saj thiab tsis pom tseeb tsw. Qhov ceev yog 1.01-1.02 g / cm³. Nws yog soluble hauv chloroform, acetone, thiab cawv, me ntsis soluble hauv benzene, thiab insoluble hauv dej thiab roj av.

• Haum rau cov roj hmab ntuj (NR) thiab cov khoom siv hluavtaws hluavtaws.
• Muaj feem xyuam rau ntau hom roj hmab, suav nrog NR, SNR, IIR, IR, SBR, NBR, thiab CR.
• Feem ntau siv ua ke nrog thiazoles, thiurams, dithiocarbamates, thiab sulfenamides los txhim kho vulcanization kev ua si.
• Tsis tshua muaj siv los ua ib qho accelerator; feem ntau yog siv los ua ib qho auxiliary accelerator hauv cov qauv roj hmab.
• Yuav siv tau los ua peptizer (yas decomposer) rau chloroprene roj hmab (CR).
• Tsis pom zoo rau zaub mov-nrog rau daim ntawv thov lossis cov khoom kho mob.

20/25kg yas woven hnab, ntawv nrog yas zaj duab xis hnab, kraft ntawv hnab.

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.

• Siv los ua qhov nruab nrab - nrawm nrawm rau cov roj hmab ntuj (NR) thiab cov roj hmab hluavtaws.
• Siv dav hauv kev tsim cov log tsheb, cov ntawv roj hmab, khau roj hmab, thiab lwm yam khoom siv roj hmab.
• Siv los ua ib qho kev pabcuam accelerator nrog thiazole thiab sulfenamide accelerators hauv NR thiab SBR formulations.
• Muab kev ruaj ntseg cia zoo dua piv nrog thiuram thiab dithiocarbamate accelerators, txawm tias muaj kev ua haujlwm qis dua.
• Nws tuaj yeem siv los ua tus neeg sawv cev pabcuam gelling (ua npuas dej stabilizer) hauv fluorinated silicone ua npuas ncauj rau daim ntaub ntawv latex.

  FAQ
