Daim Ntawv Thov Khoom

HAUVFeem ntau yog siv los ua cov kuab tshuaj rau cov roj, nitrocellulose, cov tshuaj ua los ntawm cov khoom siv hluavtaws, cov xim alcoholate thiab cov xim vinylcellulose. Hauv kev lag luam txheej, nws tuaj yeem siv los ua cov tshuaj ziab varnish thiab cov tshuaj yaj rau txheej. Hauv kev lag luam luam ntawv thiab zas xim, nws tuaj yeem siv los ua osmosis reagent thiab leveling agent. Nws kuj tseem siv tau ua cov khoom ntxiv rau kev lag luam roj thiab cov xim hauv kev lag luam textile thiab ua cov organic synthesis intermediate hauv tshuaj thiab tshuaj tua kab.

DMFeem ntau yog siv ua cov kuab tshuaj kub rau cov kua luam ntawv, cov xim zas, cov roj hmab, cellulose thiab cov xim pleev xim. Thaum muab tso rau hauv cov xim pleev xim, nws ua rau cov xim yooj yim ntws, npog thiab ntws tiaj tus. Nws kuj tseem siv tau ua cov hydrocarbon thiab cov ester derivative intermediate hauv kev lag luam synthetic. Dhau li ntawd, nws tuaj yeem siv ua cov kua nres hauv cov cav, cov tshuaj reagent hauv kev tshuaj ntsuam chemistry, thiab cov organic synthesis intermediate hauv tshuaj thiab tshuaj tua kab.

TMtuaj yeem siv ua kua nres ntawm cov motors thiab cov khoom siv raw ntawm cov organic synthesis.
