Shenyang SUNNYJOINT raws li tus neeg muag khoom ntawm roj hmab Additives, Nws paub zoo tias MBS / NOBS, TMTD, DTDM thiab lwm cov neeg txhawb nqa yuav decompose nitrosamine carcinogens nyob rau hauv cov khoom nruab nrab ntawm cov tshuaj tiv thaiv vulcanization. Yuav ua li cas xaiv kev cawm? Kuv xav siv lub qhov chaw zoo nkauj zoo nkauj kho kom haum nrog lub EU, saib hauv qab no!
Vulcanization accelerators feem ntau siv los ua cov khoom taj laj muaj xws li cov tshuab sulfenamide accelerators thiab thiazole accelerators. Lub thiazole accelerator yog non-toxic, tab sis nws lub sij hawm scorch yog luv luv, thiab qhov qeeb vulcanization tus nqi txiav txim tias qhov ntau lawm nyob rau hauv lub log yog tshwm sim raws li ib qho kev ceev nrooj, thiab tus nqi tiag tiag yog me me. Cov ntaub ntawv tseem ceeb yog cov txhawb nqa M thiab DM.
Kev ua tiav kev kawm ntawm sulfenamide accelerators nrog kev ruaj ntseg zoo, ceev ceev vulcanization thiab lub cev muaj zog thiab cov khoom siv dag zog yog thawj qhov chaw nyob rau hauv lub tsheb laij teb cov zis. Cov leeb nquag muaj xws li MBS / NOBS, TBBS / NS, CBS / CZ, DCBS. / DZ.
MBS tsim cov nitrosamines, uas tau txiav luam tawm los ntawm cov chaw lag luam hauv kev tsim cov teb chaws thiab cheeb tsam sab hnub poob. Cov khoom no tseem siv hauv Suav teb. Ib qho nyiaj tsawg ntawm thiuram accelerator feem ntau ntxiv raws li qhov thib ob lub tshuab ua zog zaum thib ob. Feem ntau siv cov khoom yog tetramethylthiuram TMTD, uas ua cov nitrosamines. Ib qho uas siv ntau yam nyob rau hauv cov hnyuv hloov tau yog dithiodimorpholine DTDM, uas kuj ua cov nitrosamines.
Qhov peb raw khoom qhia saum toj no tuaj yeem tsim nitrosamines rau cov tib neeg lub cev. Cov cai REACH uas tau cog lus los ntawm cov European Union tau hais meej tias cov khoom xa tuaj rau EU tsis pub siv cov khoom siv sab saud. Cov hauv qab no yog ntau qhov tshwj xeeb ntawm tus phooj ywg zoo rau kev siv:
1. Siv TYO / NS los siv, tab sis ntau tshaj qhov teeb meem retarder CTP yuav tsum tau ntxiv;
2. TBSI tuaj yeem siv tsis txhob N-tert-butyl-bis (2-benzothiazole) sulfenamide. Lub scorch ntawm NOBS thiab DZ, thiab tus nqi tseem qis. Lub npe TBSI cov npe N-tert-butyl-bis (2-benzothiazole) accelerator, txo lub TBSI, kuj yog ib qho kev ua zog ntawm sulfenamide. Cov khoom no siv nyob rau hauv cov compound kom ntev lub sij hawm scorch thiab qeeb ntawm qhov hloov ntawm vulcanization. Sib piv nrog TBBS, TBSI muaj lub cev muaj zog, kev thermal stability, thiab lub siab tshaj qhov siab tshaj TBSS los ntawm ntau tshaj 30 ° C. Nws muaj qhov zoo ntawm lub sij hawm ntev scorch thiab ceev ceev vulcanization. Tam sim no, TBSS feem ntau tau koom nrog cov neeg ua haujlwm qias neeg CTP, thiab TBSI tuaj yeem siv ib leeg es txhob Titan + CTP. Ntxiv rau, TBSI kuj muaj kev ruaj ntseg dej ruaj khov thiab cia tau yooj yim; nws tuaj yeem txhim kho qhov tsis kam ntawm cov roj hmab mus rau cov tshuaj sulfur thaum vulcanizing ntuj roj hmab; nws ua tau zoo nyob rau hauv cov roj hmab-steel bonded tebchaw; nws yuav raug siv nyob rau hauv tag nrho cov elastomers, tshwj xeeb tshaj yog rau cov yuav tsum tau txo txoj cai. High thickness thiab lwm yam zoo.
3. Nws tuaj yeem hloov los ntawm CBBS, thiab nws yuav tsis ua tus tsuj roj rau N-nitrosamines. Thaum nws raug hloov los ntawm NOBS hauv kev sib npaug zos, qhov sib npaug ntawm vulcanization yog sib npaug kiag. Lub scorch kev ua tau zoo me ntsis zoo dua NOBS thiab CZ. Cov khoom ntawm lub cev vulcanizate zoo ib yam li cov NOBS, thiab yog siv dav hlau lub nroog thiab lwm cov khoom siv roj hmab.
4. XT580 tuaj yeem siv tsis yog N-fatty benzothiazole sulfenamide, nws qhov kev ua tau zoo kiag li rau NOBS, tsis muaj tshuaj lom, qhov nqi qis dua NOBS.
