Phosphoric acid: raug mob los yog kev pab

Phosphoric acid los yog orthophosphoric qhib R. Boyle los ntawm dissolving lub dawb teeb meem, tsim raws li ib tug tshwm sim ntawm combustion ntawm phosphorus nyob rau hauv cov dej. Orthophosphoric acid (tshuaj mis H3PO4) hais txog inorganic acids thiab, nyob rau hauv ib txwm tej yam kev mob, nyob hauv cov ntshiab daim ntawv no, muab tsis muaj kob muaju ntawm lub orthorhombic daim ntawv. Cov muaju twb txaus hygroscopic, lawv muaj ib tug tej yam xim, nkag soluble nyob rau hauv dej thiab nyob rau hauv muaj ntau yam sib txawv kuab tshuaj.

Main chaw ntawm daim ntaub ntawv ntawm orthophosphoric acid :

• organic synthesis;
• zus tau tej cov zaub mov thiab reactive acids;
• zus tau tej cov phosphate ntsev ntawm calcium, sodium, ammonium, txhuas, manganese;
• tshuaj;
• chiv ntau lawm
• hlau ua;
• zaj duab xis ntau lawm;
• zus tau tej cov tshuab txais carbon;
• Roj kev lag luam ;
• ntau lawm ntawm refractory ntaub ntawv ;
• zus tau tej cov detergents;
• Matchbox ntau lawm.

Great tseem ceeb muaj orthophosphoric acid rau tsob nroj kev noj haus. Lawv yuav tsum phosphorus rau cov tsim ntawm txiv hmab txiv ntoo thiab noob. Phosphate chiv kom qoob loo loo. Nroj tsuag muaj muaj zog thiab resistant mus phiv tej yam kev mob. Impacting rau hauv av, chiv ua rau kom nws cov structuring, inhibit qhov kev tsim teeb meem organic tshuaj, nyiam txoj kev loj hlob ntawm pab av kab mob.

Tsiaj txhu kuj yuav tsum tau derivatives ntawm phosphoric acid. Nyob rau hauv muaj ntau yam organic tshuaj, nws koom nyob rau hauv lub metabolism. Feem ntau cov tsiaj cov pob txha, zoo li, lub koob, cov hniav, spikes, claws yog muaj li ntawm calcium phosphate. Derivatives ntawm phosphorus muaj nyob rau hauv cov ntshav, hloov hlwb, nqaij thiab connective ntaub so ntswg ntawm tib neeg lub cev.

Orthophosphoric acid tau thov nyob rau hauv kev ua lag luam. Wood, tom qab impregnation acid thiab nws cov tebchaw, yuav uas tsis yog-combustible. Los ntawm xws acid zog rau nws cov hauv paus tom zus tau tej cov nplaim taws retardant xim, nonflammable ua npuas ncauj phosphate, phospho-incombustible ntoo laug cam thiab lwm yam kev siv khoom.

Yog hais tias daim tawv nqaij orthophosphoric acid ua kub nyhiab, mob lom - ntuav, mob taub hau, kiv taub hau, ua tsis taus pa. Nws vapors nqus tau cov pa chim lub Upper pa ib ntsuj av tau thiab ua hnoos.

Phosphoric acid - ib tug khoom noj khoom haus ntxiv, uas yog muab lub code E338, ib feem ntawm cov dej haus, uas yog lub hauv paus flavorings. Tseem nws yog siv nyob rau hauv qhuav ntawm cov nqaij thiab cov hnyuv ntxwm khoom, kev cheese, thiab qab zib ntau lawm nyob rau hauv lub bakery.

Kiag li unprofitable kev tsim txom si dej haus uas muaj phosphoric acid. Qhov mob hais tias nws ua rau ib tug neeg yog ua kom lub cev acidity thiab acid-puag tshuav nyiaj li cas. "Acidification" lub cev - ib tug heev paaj ib puag ncig rau ntau yam kab mob thiab putrefaction txheej txheem. Lub cev pib mus neutralize acid los ntawm calcium, uas yog coj los ntawm cov pob txha thiab hniav. Tag nrho cov no ua rau yus txoj kev loj hlob ntawm kev kho hniav caries, pob txha fragility. Tsub kom txoj kev pheej hmoo ntawm cov pob txha lov, txha muaj thaum ntxov. Vim ntev siv E338 nyob rau hauv khoom noj khoom haus tes nrog rau tej hauj lwm ntawm lub hnyuv ib ntsuj av. Lub hnub koob tshuaj rau tib neeg noj yog tsis meej.
