Feem ntau xws acid yog ib tug 85% concentration tshuaj, uas yog ib tug kua xws li ib tug phoov nrog ib tug ua tiav tsis muaj tsw. Phosphoric acid yog nkag soluble nyob rau hauv cov dej thiab ntau cov kuab tshuaj. Piv txwv li, ethanol. Yog hais tias cov cua kub kub tshaj 213 degrees, lub yam khoom uas yog hloov dua siab tshiab rau pyrophosphoric acid.

Muaj 2 ntawm ntau yam no substance:

• siav acid;
• Kev lag luam.

Orthophosphoric acid: daim ntawv thov

Rau hnub tim, cov tshuaj thov nyob rau hauv ntau qhov chaw ntawm lawm. Qhov twg tsis tau tsuas yog raws li phosphoric acid. Nws daim ntawv thov yuav tsum tau muab faib mus rau hauv 2 hom: khoom noj khoom haus thiab uas tsis yog-zaub mov industries.

Tsis yog khoom noj orthophosphoric acid

Nyob rau hauv ntau qhov chaw ntawm ntau lawm yuav tsis ua tsis muaj ib tug tivthaiv hu ua phosphoric acid. Daim ntawv thov yuav tsum ua kom:

1. Nyob rau hauv ua liaj ua teb. Tshwj xeeb tshaj yog nyob rau hauv xws industries li ua liaj ua teb. Ib tug tov ntawm no acid yog muaj nyob rau hauv mink pub urolithiasis tiv thaiv cov tsiaj cov kab mob.
2. Nyob rau hauv science nws yog siv rau cov kev tshawb fawb ua nyob rau hauv molecular biology.
3. Nyob rau hauv ntau lawm nws yog siv raws li ib tug flux thaum lub sij hawm soldering ntawm stainless steel, tooj liab.

Yuav ua li cas nrog rau cov xeb?

Cov lus teb yog yooj yim: koj pab phosphoric acid. Kev siv cov anti-xeb cov neeg ua hauj tiv thaiv corrosion. Qhov no yog hais tias nws, tsis zoo li ntau lwm tus neeg, muaj kev ruaj ntseg rau hlau. Ua orthophosphoric acid txhawb cov tsos ntawm tus nto tiv thaiv zaj duab xis uas tiv thaiv ntxiv kev puas tsuaj. Nws feem ntau tshwm nyob rau hauv cov xov xwm, uas yog ua rau sib ntaus sib tua xeb. Yog li ntawd, nws yog siv nyob rau hauv lub tsev so thiab tsev noj mov ua lag ua luam.

Puas orthophosphoric acid

Txawm li cas los, (nrog rau qhov zoo), muaj tsis zoo ntawm kev siv orthophosphoric acid.

1. Nws yog peev xwm ua rau lub acidity ntawm lub cev, thiab yog li chim siab qhov nqi koj tshuav.
2. Nws tsis zoo muaj feem xyuam rau cov calcium. Nws displaces nws los ntawm cov hniav thiab cov pob txha. Yav tas los nyob rau hauv kev kho hniav rau tshem txha hniav laus orthophosphoric acid yog feem ntau siv. Cov kev siv raug txwv nyuam qhuav rau qhov no yog vim li cas.
3. Txhua hnub siv ntawm no substance nyob rau hauv khoom noj khoom haus yuav ua tau kom ntuav, xeev siab, tsis muaj qab los noj mov.
4. Tau txais nyob rau hauv daim tawv nqaij, orthophosphoric acid ua mob loj heev kev kub nyhiab.

Txawm nws yog, rau kev siv cov tshuaj yeeb dej caw tso cai nyob rau lub teb chaws ntawm Russia, lub EU thiab cov qub CIS. Rau muaj kuab thiab skilful siv phosphoric acid yog ib tug lossis loj kev pab.
