Kev siv L-tartaric acid
【Siv 1】 L(+)-tartaric acid yog dav siv los ua cov kua qaub hauv dej haus thiab lwm yam khoom noj, siv rau hauv cawv, dej qab zib, khoom qab zib, qhob cij, thiab qee cov khoom qab zib colloidal.Feem ntau yog siv los ua cov kua qaub, tus neeg sawv cev sib cais thiab cov khoom siv tshuaj
【Siv 2】 Siv los ua biochemical reagent, masking agent thiab npias foaming agent, kuj siv hauv kev lag luam tanning
【Siv 3】 L(+)-tartaric acid yog dav siv los ua cov kua qaub hauv dej haus thiab lwm yam khoom noj, siv rau hauv cawv, dej qab zib, khoom qab zib, qhob cij, thiab qee cov khoom qab zib colloidal.Siv nws cov kev ua haujlwm kho qhov muag, nws tuaj yeem siv los ua cov tshuaj daws teeb meem rau kev daws teeb meem ntawm DL-aminobutanol, ib qho nruab nrab hauv kev tsim cov tshuaj tiv thaiv kab mob;nws kuj tseem siv tau los ua chiral raw khoom rau kev sib txuas ntawm tartaric acid derivatives;nws acidity yuav siv tau raws li polyester ntaub cob Catalyst rau xov, PH regulator rau oryzanol ntau lawm;Siv nws cov cuab yeej complexing, nws yog siv raws li complexing tus neeg saib xyuas, masking tus neeg saib xyuas, chelating tus neeg saib xyuas, luam ntawv thiab dyeing tiv thaiv nyob rau hauv electroplating, desulfurization, pickling, tshuaj ntsuam xyuas thiab kev kho mob tshuaj;Nws qhov txo qis yog siv los ua tus neeg sawv cev txo qis rau kev ua cov iav tshuaj.Tus tsim tawm yees duab.Nws tuaj yeem ua haujlwm nrog ntau yam hlau ions, thiab tuaj yeem siv los ua tus neeg saib xyuas thiab polishing tus neeg sawv cev rau cov hlau nto.
【Siv 4】 Siv nws cov cuab yeej complexing, nws yog siv raws li ib tug complexing neeg sawv cev, masking neeg sawv cev, chelating tus neeg saib xyuas, thiab dyeing tiv thaiv nyob rau hauv electroplating, desulfurization, pickling, tshuaj ntsuam xyuas thiab kev kho mob tshuaj;siv nws cov khoom txo qis, nws yog siv los ua cov tshuaj Mirror txo tus neeg sawv cev.Tus tsim tawm yees duab.Nws tuaj yeem ua haujlwm nrog ntau yam hlau ions, thiab tuaj yeem siv los ua tus neeg saib xyuas thiab polishing tus neeg sawv cev rau cov hlau nto.
