Phosphoric acidyakajairika inorganic asidhi ine kemikari formula H3PO4.Haisi nyore kuvhuvhuta, isiri nyore kuora, iri nyore kuita deliquescence mumhepo.Phosphoric acid iasidhi yepakati-yakasimba ine crystallization point ye21°C.Kana tembiricha yadzikira pane tembiricha iyi, hemihydrate makristasi anozodzikiswa.Kupisa kunorasikirwa nemvura kuti uwane pyrophosphoric acid, uyezve kurasikirwa nemvura kuti uwane metaphosphoric acid.Phosphoric acid ine pfuma yeasidhi, acidity yayo haina kusimba kupfuura hydrochloric acid, sulfuric acid, nitric acid, asi yakasimba kupfuura acetic acid, boric acid, nezvimwe.
shandisa:
Mushonga: Phosphoric acid inogona kushandiswa kugadzira mishonga ine phosphorus, yakadai sesodium glycerophosphate.Zvekurima: Phosphoric acid chinhu chakakosha chekugadzira phosphate fertilizer (superphosphate, potassium dihydrogen phosphate, nezvimwewo), pamwe chete nekugadzirwa kwezvokudya zvekudya (calcium dihydrogen phosphate);
Zvokudya: Phosphoric acid ndeimwe yezvinowedzera zvekudya.Inoshandiswa seyakavava mumiriri uye mbiriso chikafu mukudya.Coca-Cola ine phosphoric acid.Phosphate zvakare yakakosha chikafu chekuwedzera uye inogona kushandiswa sechikafu chinowedzera;
Indasitiri: Phosphoric acid ikemikari yakakosha mbishi zvinhu, uye mabasa ayo makuru ndeaya anotevera;
1. Bata simbi pamusoro kuumba insoluble phosphate firimu pamusoro simbi pamusoro kudzivirira simbi kubva ngura;
2. Yakasanganiswa ne nitric acid sekemikari yekuchenesa makemikari kuvandudza kutsetseka kwesimbi;
3. Phosphate esters, midziyo yekugadzira mishonga yekuchenesa nemishonga yezvipembenene;
4. Raw materials yekugadzira phosphorus-ine flame retardants;
Kuchengetedza kana uchishandisa phosphoric acid:
Kuti udzivirire ganda kubva kune phosphoric acid, tinokurudzira kupfeka zvipfeko zvekudzivirira zvemakemikari zvakadai sebhutsu, zvipfeko zvekudzivirira uye magirovhosi, tinokurudzirawo kuti utenge matehwe akagadzirwa nerabha rakasikwa, polyvinyl chloride, nitrile rubber, butyl rubber kana neoprene giya rekudzivirira.
Kuti udzivirire chiso kana maziso kubva kune zvinogumbura uye zvinopisa zvinhu, tinokurudzira kushandiswa kwekuchengetedza magirazi ekudzivirira kemikari.
Pamusoro pekufefetedza kwemhepo, isu tinokurudzira kushandiswa kwemhepo yekufemesa yemuno kudzivirira njodzi dzekufema kana uchishandisa phosphoric acid, zvese zvinodikanwa zvekuchengetedza kwezvakatipoteredza zvinofanirwa kutorwa, uye utsi hunogona kuda kuburitswa kunze.
