Kev Siv
Qhov qauv tshwj xeeb ntawm MXDA txiav txim siab tias nws muaj ntau yam khoom zoo heev thiab tshuaj lom neeg, yog li nws tau siv dav. MXDA thiab nws cov cyclic hydrides tuaj yeem siv ua cov neeg sawv cev rau epoxy resins, nrog rau kev ua haujlwm zoo heev hauv chav tsev kub, tiv taus cua sov zoo, tiv taus dej, thiab tiv taus tshuaj lom neeg corrosion. Ntxiv mus, lawv tuaj yeem tsim cov pob tshab thiab zoo heev-ua tiav cov resins kho nrog viscosity qis thiab ua haujlwm zoo. Tib lub sijhawm, MXDA yog ib qho tseem ceeb tshuaj intermediate, uas tuaj yeem synthesize polyamides nrog dibasic acids, thiab tuaj yeem synthesize m-xylene diisocyanate, ib tug monomer ntawm polyurethane. Nws cov benzene nplhaib hydrides kuj tuaj yeem siv los synthesize diisocyanates. Tam sim no, nws tau siv rau hauv kev tsim cov roj hmab crosslinking agents, tshuaj tua kab, fiber stabilizers, surfactants, thiab lwm yam.
1,3-Benzenedimethylamine feem ntau yog siv rau kev tsim cov tshuaj epoxy resin uas ua haujlwm tau zoo uas tiv taus kub, tsis muaj tshuaj lom, tsim nyog rau kev tsim kho hauv qab dej, thiab muaj peev xwm kho sai sai thaum cua sov. Nws ua haujlwm ua cov khoom siv raw rau polyurethane resins thiab cov tshuaj epoxy resins ua haujlwm, thiab kuj siv rau hauv cov teb ntawm cov roj hmab pabcuam, cov yas photosensitive, tshuaj tua kab, tshuaj pleev xim, cov khoom nylon, cov tshuaj ua tiav fiber, cov tshuaj tiv thaiv xeb, cov tshuaj chelating, cov roj nplua nyeem, kev ua ntawv, thiab lwm yam.
Nws yog siv rau kev npaj cov tshuaj tua kab epoxy resin, cov yas uas rhiab heev rau cov duab, cov roj hmab pab, cov polyurethane resins, cov tshuaj pleev xim, thiab lwm yam. Nws yog siv rau kev tsim cov tshuaj tua kab epoxy resin uas ua haujlwm tau zoo uas tiv taus kub, tsis muaj tshuaj lom, tsim nyog rau kev tsim kho hauv qab dej, thiab tuaj yeem kho sai sai thaum cua sov. Nws ua haujlwm ua cov khoom siv raw rau polyurethane resins thiab cov tshuaj epoxy ua haujlwm, thiab kuj siv rau hauv cov teb ntawm cov tshuaj pab roj hmab, cov yas uas rhiab heev rau cov duab, cov tshuaj tua kab, cov tshuaj pleev xim, cov khoom nylon, cov tshuaj ua tiav fiber, cov tshuaj tiv thaiv xeb, cov tshuaj chelating, cov roj nplua nyeem, kev ua ntawv, thiab lwm yam.
