Dibasic sodium phosphate

Cov lus piav qhia luv luv:

Nws yog ib qho ntawm cov ntsev sodium ntawm phosphoric acid. Nws yog deliquescent dawb hmoov, soluble hauv dej, thiab cov kua aqueous yog qhov tsis muaj zog alkaline. Disodium hydrogen phosphate yog ib qho yooj yim rau huab cua hauv huab cua, rhuab rau hauv cov pa roj crystal mus rau hauv cov pa roj crystal mus rau hauv cov pa roj crystal, decompost rau sodium pyrophosphate ntawm 250 ℃.

Disodium hydrogen phosphate yooj yim yooj yim tsib molecules ntawm cov siv lead ua kom tsim tau heptahydrate (na2hpo4.7h2o). Cov kev daws teeb aque yog me ntsis alkaline (PHY ntawm 0.1-1N daws yog kwv yees li 9.0). Ntawm 100 ° C, cov dej siv lead ua ploj thiab dhau los ua anhydrous, thiab ntawm 250 ° C, nws yog decomposed rau hauv sodium pyrophosphate. Tus nqi PH ntawm 1% kev daws teeb meem yog 8.8 ~ 9.2; Insoluble hauv cawv. Qhuav ntawm 35.1 ℃ thiab poob 5 Crystal dej.

Lus xab npum / Luam Ntawv

Yuav ua citric acid, watering muag tus neeg sawv cev, qhov hnyav textile, hluav taws retardant tus neeg sawv cev. Thiab qee cov phosphates tuaj yeem siv los ua cov tshuaj tiv thaiv kev kho mob, cov tshuaj tiv thaiv kab mob thiab kho mob biochemical thiab cov tshuaj kho mob buffer thiab ci cov ntaub ntawv nyoos. Nws yog siv rau hauv ci, siv tshuaj, tshuaj, xim, kev lag luam khoom noj khoom haus emulphes, zoo li kev pabcuam dej, cov khoom noj muaj txiaj ntsig zoo, chelating tus neeg sawv cev thiab stabilizer thiab stabilizer. Nws yog siv rau kev tsim cov tshuaj ntxuav tshuaj, ntxuav cov neeg sawv cev rau luam tawm daim hlau thiab mordant rau dyeing. Hauv kev luam ntawv thiab zas kev lag luam, nws yog siv los ua cov stabrogen peroxide dawb huv thiab ib tug muab tub lim rau Rayon (los txhim kho lub zog thiab elasticity ntawm cov lo lo ntxhuav). Nws yog kab lis kev cai tus neeg sawv cev rau Monosodium Glutamate, Erythromycin, penicillin, streptomycin thiab dej khib nyiab thiab kho khoom.
