CAS Nr.: 868-14-4
Lub ntsiab lus: acid potassium tartrate
Lub cev thiab tshuaj muaj zog
Dawb crystalline hmoov los yog dawb crystalline hmoov, tsw, nrog ib tug txias qaub saj. Nws yog carbonized tom qab muaj zog cua sov, thiab muaj ntxhiab tsw qab zib hlawv. Tus txheeb ze ntom ntom yog 1.956. Lub solubility hauv dej sib txawv nrog qhov kub thiab txias. Nws yog qhov nyuaj rau yaj hauv dej txias (0.84g / 100ml, 25 degree C thiab ethanol 0.0001g / 100ml, qhov kub thiab txias) thiab soluble hauv dej kub (6.9g / 100ml, 100 degree C). Tus nqi pH ntawm saturated aqueous tov yog 3.66 (17. degrees. C.). Nws yog ib qho nruab nrab soluble ob ntsev nyob rau hauv poov tshuaj hydroxide los yog poov tshuaj carbonate tov thiab yog precipitated dua tom qab ntxiv acid.
Tartar, ib tug by-product ntawm wine brewing, yog ntxiv crystallized nrog acid los yog alkali tom qab dej extraction; Los yog los ntawm kev ua ntawm tartaric acid nrog potassium hydroxide lossis potassium carbonate.

Daim ntawv thov
Bulking agent
GB 2760-2014 qhia tias nws tuaj yeem siv rau cov hmoov nplej thiab nws cov khoom thiab cov zaub mov ci, thiab tuaj yeem siv rau qhov tsim nyog raws li kev xav tau ntau lawm.
Cov khoom no tsuas yog siv los ua cov khoom siv raw rau cov neeg ua haujlwm sib xyaw ua ke. Thaum siv los ua cov khoom sib xyaw ua ke rau ci zaub mov, nws cov ntsiab lus yog 10 feem pua ~ 25 feem pua. Yog tias 30-40g ntawm tus neeg sawv cev bulking yog siv rau ib kilogram ntawm hmoov, 3-10g ntawm poov tshuaj hydrogen tartrate muaj nyob rau ib kilogram ntawm hmoov.
