Cov neeg uas paub txog kev lag luam roj hmab chemicals paub hais tias cov khoom nruab nrab ntawm TMTD (TT) thiab lwm yam roj hmab accelerators yuav tsim cov nitrosamine carcinogens. Koj yuav xaiv li cas? Yog tias koj xav siv lub chaw ua haujlwm zoo phooj ywg los kho nrog lub EU, thov mus saib SUNNYJOINT qhov kev taw qhia.
Accelerator TMTD kev hloov
Kev siv TBZTD (tetrabenzyl thiuram disulfide) kuj siv tau, nrog rau qhov kev nyab xeeb ntawm kev nyab xeeb thiab kev ua haujlwm rau kev hloov; TBZTD lub npe yog tetrabenzyl thiuram disulfide, tau muab hu ua TBZTD. Cov khoom no yog ib qho qauv tshiab thiuram accelerator, nws muaj peev xwm hloov TMTD (tetramethyl disulfide thiuram), nws tuaj yeem raug siv los ua cov roj hmab, qhov yoojyim ua kom ceev nrooj los yog lub zog rau styrene-butadiene roj hmab thiab styrene butadiene roj hmab. Txoj kev ruaj ntseg dua thiab muaj lub sij hawm ntev dua TMTD. Vim tias TBZTD muaj lub cev loj heev thiab lub siab melting point, nws nyuaj rau decompose, thiaj li tsis muaj nitrosamines. Hauv particular, TBZTD tsuas yog qis me ntsis hauv qhov ntxhov ntxhov siab ntau dua li TMTD, thiab lwm yam khoom hauv lub cev yuav luag zoo ib yam li TMTD, thiab nws tau dhau los ntawm cov thiuram. Vulcanization accelerator tshiab ntau yam.
Txawm hais tias TBZTD tseem yog ib hom thiuram, qhov tshwm sim dibenzyl nitrosoamine ua rau yog cov khoom uas tsis yog cov carcinogenic uas tsis muaj dej cawv lossis tsis tov dej hauv vim nws lub cev loj loj, thiab qhov khoom ntawm cov khoom no me me, vim tias nws yog tsis-ncov qaum, Frost tsis tuaj. TBZTD tseem muaj qhov zoo ntawm kev kho lub sijhawm ntev thiab muaj kev nyab xeeb zoo. Nws yog tsim rau lub hnab roj hmab, cov roj hmab, butadiene rubber, styrene-butadiene roj hmab, nitrile roj hmab, butyl roj hmab, EPDM roj hmab thiab latex. Nws yog dav siv. Raug kev xaim hlau thiab kab, tshuab raj, siv kaspes, xim pob tshuam khoom, khau thiab cov khoom kub-resistant, thiab lwm yam., Yuav siv los hloov thiuram accelerators xws li TMTD thiab TETD.
