Tannic acid CAS 1401-55-4
Tannic acid tuaj yeem siv rau hauv tanning, number case manufacturing, ntawv thiab txhob lo lo ntxhuav gluing, boiler descaling, thiab lwm yam. Tannic acid kuj yuav siv tau raws li ib tug mordant, ib tug clarifying tus neeg saib xyuas rau npias thiab caw, thiab coagulant rau roj hmab. Tannic acid yuav siv tau nyob rau hauv kev lag luam xws li luam ntawv thiab dyeing, metallurgy, tshuaj, thiab lwm yam. Tannic acid lub inherent toxicity yog tsawg heev. Kev txiav txim siab los nag thiab qhov hnyav ntawm beryllium, aluminium, gallium, indium, niobium, tantalum, thiab zirconium. Kev txiav txim siab ntawm tooj liab, hlau, vanadium, cerium, thiab cobalt. Ib tug precipitant rau proteins thiab alkaloids. Sab nraud qhov taw qhia rau ammonium molybdate titration ntawm txhuas. Dye mordant.
