Kev siv
Organic Synthemes Raw Khoom:
1,3, {5- Trimethylbzene yog siv los tsim cov neeg sawv cev, epoxy} Cov ntaub ntawv tshem tawm, thiab tom qab ntawd syneth} Cov ntaub ntawv pov thawj, thiab tom qab ntawd syneth} Cov ntaub ntawv tshem tawm, thiab tom qab ntawd syneth} Cov ntaub ntawv tshem tawm, thiab tom qab ntawd syneth} Cov ntaub ntawv tshem tawm, thiab tom qab ntawd syneth} Cov ntaub ntawv tshem tawm, thiab tom qab ntawd syneth} Cov ntaub ntawv pov thawj, thiab tom qab ntawd squeeter tshem tawm ntawm cov refreating ci ntsa iab, K -3 r thiab lwm tus tuag.
High boiling point cov kuab tshuaj:
Vim nws cov kuab lom tsawg thiab zoo solubility, nws yog dav siv nyob rau hauv txheej, number case, thiab kev lag luam roj hmab kom kho cov khoom voscosity thiab tus nqi kom qhuav; Nws yog siv los ua cov yeeb yaj kiab silicone silicone silicone
Cov Ntaub Ntawv Kev Nyab Xeeb
1,3, {5- trimethylbzene yog me ntsis lom, nrog cov tshuaj lom zoo ib yam li ntawm xylene. Kev nqus tau ntawm siab-siab txog vapor tuaj yeem ua pa rau cov ua pa, thiab lub sijhawm sib cuag lub siab ntev yuav ua rau lub siab thiab cov leeg hlwb. Cov tawv nqaij sib cuag tuaj yeem ua rau muaj kev tiv thaiv dermatitis. Qhov siab tshaj plaws tso cai pom hauv huab cua yog 125mg / m³. Hnav cov khoom tiv thaiv uas ua haujlwm thaum ua haujlwm thaum muaj hluav taws, khaws rau qhov chaw txias thiab muaj qhov cua, thiab khaws cais los ntawm oxidants. Thaum muaj kev xau, siv xuab zeb lossis inert cov ntaub ntawv kom tiv thaiv cov kuab paug dej.
