Dibasic Sodium Phosphate

piav qhia luv luv:

Nws yog ib qho ntawm cov ntsev ntsev ntawm phosphoric acid.Nws yog deliquescent dawb hmoov, soluble nyob rau hauv dej, thiab cov aqueous tov yog weakly alkaline.Disodium hydrogen phosphate yog ib qho yooj yim rau huab cua nyob rau hauv cov huab cua, nyob rau hauv chav tsev kub muab tso rau hauv cov huab cua kom poob li ntawm 5 siv lead ua dej los tsim heptahydrate, rhuab mus rau 100 ℃ kom poob tag nrho cov siv lead ua dej rau hauv anhydrous teeb meem, decomposition rau sodium pyrophosphate ntawm 250 ℃.

Khoom siv

Detergent / luam ntawv

Yuav ua rau citric acid, dej softening neeg sawv cev, ib co textile hnyav, hluav taws kub retardant tus neeg saib xyuas.Thiab qee qhov phosphates tuaj yeem siv los ua tus neeg saib xyuas dej zoo, dyeing detergent, dyeing aid, neutralizer, tshuaj tua kab mob kab lis kev cai, tus neeg saib xyuas kev kho mob biochemical thiab kev hloov pauv zaub mov hauv fermentation tsis thiab ci hmoov raw khoom.Nws yog siv rau hauv glaze, solder, tshuaj, pigment, zaub mov kev lag luam thiab lwm yam phosphates raws li muaj dej kho tus neeg saib xyuas emulsifier, zoo improver, as-ham fortification agent, fermentation pab, chelating tus neeg saib xyuas thiab stabilizer.Nws yog siv nyob rau hauv zus tau tej cov detergents, ntxuav cov neeg ua hauj rau luam daim hlau thiab mordant rau dyeing.Hauv kev lag luam luam ntawv thiab dyeing, nws yog siv los ua ib qho stabilizer rau hydrogen peroxide bleaching thiab muab tub lim rau rayon (los txhim kho lub zog thiab elasticity ntawm cov lo lo ntxhuav).Nws yog ib tug kab lis kev cai tus neeg sawv cev rau monosodium glutamate, erythromycin, penicillin, streptomycin thiab dej khib nyiab tsim thiab kho cov khoom.

Khoom noj khoom haus additive (Food grade)

Raws li kev txhim kho zoo, PH regulator, nutrient enhancer, emulsifying dispersant, fermentation pab, nplaum thiab lwm yam.Nws yog tsuas yog siv nyob rau hauv pasta, soy khoom, khoom noj siv mis, nqaij, cheese, dej haus, txiv hmab txiv ntoo, ice cream thiab ketchup, thiab feem ntau yog 3-5% nyob rau hauv cov khoom noj.
