Daim ntawv thov
Sulfur pub vulcanizing tus neeg saib xyuas kom ua tau zoo vulcanization thiab semi-kev ua haujlwm zoo vulcanization kho; muab cua sov / thim rov qab / kev laus ua haujlwm hauv NR thiab hluavtaws roj hmab; tsis yog-bloom; kev ruaj ntseg zoo heev.
Nws tuaj yeem siv los ua tus neeg sawv cev vulcanizing thiab accelerator rau ob qho tib si ntuj thiab hluavtaws roj hmab. Thaum siv los ua tus neeg sawv cev vulcanizing, nws decomposes tso tawm cov tshuaj sulfur nkaus xwb ntawm qhov kub ntawm vulcanization, ua rau nws siv kev nyab xeeb thiab tiv thaiv scorching. Thaum nws cov vulcanization ceev qeeb thaum siv ib leeg, nws tuaj yeem nce ntxiv thaum siv nrog cov accelerators xws li thiazoles, thiurams, lossis dithiocarbamates. Txawm hais tias salicylic acid-raws li cov kua qaub tuaj yeem txhawb nqa nws cov decomposition thiab ua kom cov vulcanization, lawv tuaj yeem txo cov khoom ntawm lub cev ntawm cov roj hmab vulcanized. Thaum siv los ua ib qho accelerator, tus naj npawb ntawm cov sulfur siv tau raug txo kom tsim nyog vim nws cov ntsiab lus sulfur zoo. Kev siv cov khoom no tiv thaiv kev tawg, kev kis kab mob, thiab discoloration ntawm cov roj hmab compound. Thaum siv rau hauv kev ua tau zoo thiab ib nrab -vulcanization tshuab zoo, qhov ua rau cov roj hmab vulcanized ua rau muaj kev kub ntxhov thiab kev laus ua haujlwm.
Kev Tiv Thaiv Kev Tiv Thaiv
Yog xav paub ntxiv txog kev tiv thaiv toxicological thiab kev tuav pov hwm, thov mus saib Daim Ntawv Qhia Kev Nyab Xeeb tam sim no. Daim ntawv qhia no tuaj yeem thov los ntawm Great Choj Chemical thiab yuav tsum tau sab laj ua ntej siv cov khoom no.
Ntim

Cia
Khaws Great Choj Chemical DTDM nyob rau hauv ib qho khoom pallets nyob rau hauv ib qho chaw txias, qhuav, zoo ventilated, tsis txhob raug cov khoom ntim rau lub hnub ncaj qha. Muab ob npaug rau ntawm cov khoom palletized tuaj yeem ua rau cov khoom sib txawv txawv. Cov av noo siab thiab / lossis kub tuaj yeem ua rau degradation uas tuaj yeem ua rau lub sijhawm luv luv. Tsis txhob khaws cov khoom no ze Crystex vim tias cov amine vapors tus yam ntxwv tawm ntawm cov khoom no tuaj yeem ua rau Crystex rov qab mus rau "Rubber Maker's" sulfur.
