Trisodium phosphate CAS 7601-54-9
Trisodium phosphate, tseem hu ua 'sodium orthophosphate'. Cov mis tshuaj yog Na3PO4 · 12H2O. Tsis muaj xim rau cov koob dawb zoo li siv lead ua los yog hmoov crystalline, nrog lub melting point ntawm 73.4 ° C rau dodecahydrate. Yaj hauv dej, cov kua dej ua rau muaj zog alkalinity vim muaj zog hydrolysis ntawm phosphate ions (PO43-); Insoluble hauv ethanol thiab carbon disulfide. Nws yooj yim rau deliquescence thiab weathering hauv huab cua qhuav, tsim sodium dihydrogen phosphate thiab sodium bicarbonate. Yuav luag tag nrho decomposed rau hauv disodium hydrogen phosphate thiab sodium hydroxide hauv dej. Trisodium phosphate yog ib qho ntawm cov khoom tseem ceeb hauv kev lag luam phosphate, siv dav hauv kev lag luam tshuaj niaj hnub, kev ua liaj ua teb thiab kev yug tsiaj, roj av, papermaking, detergents, ceramics thiab lwm yam teb vim nws cov khoom tshwj xeeb.

Trisodium phosphate yog ib yam khoom siv uas khaws cov dej noo hauv kev lag luam zaub mov, nws siv rau hauv cov khoom noj hauv qab, cov dej haus kua txiv hmab txiv ntoo, cov khoom noj mis nyuj, cov khoom noj nqaij, cheese, thiab dej haus. Siv ua cov tshuaj ua kom dej mos thiab tshuaj ntxuav hauv kev lag luam xws li tshuaj lom neeg, ntaub, luam ntawv thiab zas xim, ua ntawv, thiab tsim hluav taws xob, tshuaj tiv thaiv kev tawg ntawm lub boiler, tshuaj ua kom dej mos hauv kev zas xim ntawv, tshuaj ua kom pH buffering rau cov nplaum siv hauv kev tsim ntawv ciab, tshuaj kho thaum luam ntawv thiab zas xim, tshuaj ua kom cov ntaub lo lo ntxhuav ci ntsa iab, thiab tshuaj tiv thaiv kev tawg rau cov kab ntau lawm. Kev lag luam hlau siv ua tshuaj ntxuav roj thiab tshuaj ntxuav, thiab ua tus txhawb nqa zoo heev hauv kev daws teeb meem kev tsim duab. Tshuaj ntxuav hniav thiab tshuaj ntxuav lub raj mis. Tshuaj coagulant rau mis roj hmab. Tshuaj ntxuav kua qab zib.
