Kev Qhia:

Feem ntau, DTDM / TMTD siv sib xyaw ua ke, los yog sulfenamide los yog thiazole accelerator siv los kho lub sij hawm scorch thiab qhov siv tshuaj ntxhua.

Tus sawv cev DTDM siv tau hloov mus rau qhov ntsuas kub ntawm 140 ° C-200 ° C, thiab qhov kev nyab xeeb ntawm scorch yog qhov zoo. Tom qab ncav cuag lub cev qhov kub li qub, qhov hloov qhov ceev nrooj yog accelerated, thiab cov khoom vaj huam sib luag ntawm lub cev yog qhov zoo tagnrho. DTDM tsis siv tshuaj tsuag, tsis muaj kev phom sij, thiab yooj yim los faib rau hauv cov khoom siv roj, thiab muaj kev ua tau zoo. DTDM yuav rub tawm cov khoom siv roj hmab ntau dua nrog cov khoom siv high-efficiency vulcanization, uas muaj peev xwm ua tau kom muaj kev tiv thaiv ntawm vulcanizates. DTDM tuaj yeem tsim tau morpholine dawb radicals nrog amine antioxidants nyob rau hauv lub hnab roj hmab, uas tuaj yeem ua rau cov roj hmab uas muaj ntaub nplaum tau zoo heev thiab oxidation kuj. DTDM muaj cov thermal khoom zoo heev thiab zoo tagnrho rau kev tsim cov khoom siv hluav taws xob rau cov khoom cua kub-resistant. Nws tuaj yeem txo qhov kub-generating NR thiab SNR thiab yog ib qho zoo tshaj plaws roj hmab vulcanizing tus neeg sawv cev.

Nrog cov neeg tiv thaiv ib puag ncig kev tiv thaiv thiab kev txhawj xeeb txog kev noj qab haus huv, nws tau raug pom tias cov tshuaj lom neeg DTDM thiab thiuram cov khoom yuav muab tso rau hauv qhov ntsuas kub kom tso tawm ob theem siab dua rau cov amino-molecular tawg, uas tau muab tso nrog cov nitroso pub los ua carcinogens . Nitrosamines, yog li cov khoom siv thiab cov ntaub ntawv ntawm cov khoom siv ntxhov siab DTDM thiab thiurams yuav raug rau cov kev txwv thiab cov lus ceeb toom ntawm cov tebchaws nyob sab Europe thiab Asmeskas thiab tej cai ntawm ib puag ncig. Tam sim no, tus neeg sawv cev tshiab uas siv DTDC (N, N-N (di-caprolactam) disulfide) tau nyiam cov xim thoob ntiaj teb vim qhov tseeb nws tsis tsim cov nitrosamines thaum lub sij hawm vulcanization. Nws yog qhov ua rau tus cev ntxhiab tsw phem DTDM thiab disulfide los yog hexasulfurate. Qhov zoo tshaj plaws rau M, qhov hloov lub cev hloov DTDM nrog tus nqi tib yam, tsis tas hloov cov formulation thiab txheej txheem ntawm lub compound
