Phosphoric lossis orthophosphoric acid tau tshawb pom los ntawm R. Boyle los ntawm kev yaj cov teeb meem dawb tsim los ntawm kev sib xyaw ntawm phosphorus hauv dej. Orthophosphoric acid (tshuaj formula H3PO4) yog hais txog inorganic acids thiab nyob rau hauv ib txwm tej yam kev mob, nyob rau hauv nws cov ntshiab daim ntawv, yog sawv cev los ntawm tsis muaj kob rhombic crystals. Cov crystals no yog hygroscopic heev, tsis muaj xim meej, thiab yooj yim yaj hauv dej thiab ntau cov kuab tshuaj sib txawv.
Daim ntawv thov tseem ceeb ntawm phosphoric acid:
- organic synthesis;
- tsim khoom noj thiab cov kua qaub;
- tsim cov phosphate ntsev ntawm calcium, sodium, ammonium, aluminium, manganese;
- tshuaj;
- chiv ntau lawm
- kev lag luam hlau;
- ua kom cov pa roj carbon ntau lawm;
- kev lag luam roj;
- tsim cov khoom siv refractory;
- tsim cov tshuaj ntxuav tes;
- match production.
Tus nqi loj orthophosphoricacid yuav tsum pub cov nroj tsuag. Lawv xav tau phosphorus los tsim cov txiv hmab txiv ntoo thiab noob. Phosphate chiv nce qoob loo. Nroj tsuag ua Frost-resistant thiab resistant rau tej yam kev mob phem. Los ntawm kev cuam tshuam cov av, chiv pab txhawb rau nws cov qauv, inhibit tsim cov organic teeb meem, thiab txhawb kev loj hlob ntawm cov kab mob hauv av.
Tsiaj txhu kuj xav tau cov tshuaj orthophosphoric acid derivatives. Ua ke nrog ntau yam organic tshuaj, nws koom nrog hauv cov txheej txheem metabolic. Hauv cov tsiaj feem ntau, pob txha, plhaub, koob, hniav, spikes, thiab claws yog tsim los ntawm calcium phosphate. Phosphorus derivatives muaj nyob rau hauv cov ntshav, lub hlwb, connective thiab cov leeg nqaij ntawm tib neeg lub cev.
Orthophosphoric acid kuj tau pom daim ntawv thov hauv kev lag luam. Ntoo, tom qab impregnation nrog acid thiab nws cov tebchaw, yuav tsis-combustible. Vim yog cov khoom siv ntawm cov kua qaub no, nws tau siv los ua cov nplaim hluav taws kub hnyiab, nplaim hluav taws phosphate ua npuas ncauj, nplaim hluav taws phosphorus ntoo boards thiab lwm yam khoom siv hauv tsev.
Yog tias nws nkag mus rau hauv daim tawv nqaij, phosphoric acid ua rau kub hnyiab, thaum mob hnyav - ntuav, mob taub hau, kiv taub hau, ua tsis taus pa. Nws cov vapors, thaum nqus tau, ua rau cov mucous daim nyias nyias ntawm txoj hlab pa sab sauv thiab ua rau hnoos.
Orthophosphoric acid yog cov khoom noj ntxiv, uas tau muab rau tus lej E338, uas yog ib feem ntawm cov dej qab zib raws li flavorings. Nws kuj yog siv hauv kev tsim khoomnqaij thiab hnyuv ntxwm khoom, tiav cheeses, qab zib-ua thiab ci ci.
Kev tsim txom cov dej qab zib uas muaj phosphoric acid tsis zoo kiag li. Qhov teeb meem uas nws ua rau ib tug neeg yog ua kom cov acidity ntawm lub cev thiab cuam tshuam cov acid-base tshuav nyiaj li cas. "Acidification" ntawm lub cev yog ib qho chaw zoo heev rau ntau yam kab mob thiab cov txheej txheem ntawm kev lwj. Lub cev pib neutralize cov kua qaub nrog kev pab ntawm calcium, uas yog qiv los ntawm cov pob txha thiab cov hniav. Tag nrho cov no ua rau txoj kev loj hlob ntawm cov hniav caries, pob txha fragility. Kev pheej hmoo ntawm pob txha pob txha nce ntxiv, osteoporosis ntxov tshwm sim. Vim yog kev noj ntau dhau ntawm E338 hauv cov zaub mov, kev ua haujlwm ntawm lub plab zom mov yog cuam tshuam. Kev noj tshuaj txhua hnub rau tib neeg tsis tau tsim.
