Physicochemical properties:
1. Mvura inoonekera isina ruvara,Isina kunhuhwirira
2.Melting point 42℃;kuvira poindi 261℃.
3.Miscible nemvura mune chero ratio
Storge:
1. Chengetedza muimba yekuchengetera inotonhorera, ine mhepo.
2. Chengetedza kure nemoto nekupisa.
3. Iyo pasuru yakavharwa.
4. Inofanira kuchengetwa zvakasiyana kubva nyore (zvinopisa) zvinopisa, alkalis, uye mashizha anoshingaira esimbi, uye kudzivisa kusanganiswa kwakasanganiswa.
5. Nzvimbo yekuchengetera inofanira kunge yakashongedzerwa nezvinhu zvakakodzera kuti ive nekudonha.

Kushandisa zvekurima: mbishi zvinhu zvephosphate fetiraiza uye kudya kunovaka muviri
Indasitiri kushandiswa: makemikari mbishi zvinhu
1.Chengetedza simbi kubva pakuora
2. Yakasanganiswa ne nitric asidhi semakemikari polishing agent kuti ivandudze kupera kwesimbi
3.Zvinhu zvephosphatide iyo inoshandiswa kugadzira chigadzirwa chekugeza uye mishonga yezvipembenene
4.Kugadzirwa kwe phosphorus ine flameretardant zvinhu.
Zvekuwedzera zvekudya zvinoshandisa: acidic flavour, Yeast Nutri-ents, senge coca-cola.
Kushandiswa kwekurapa: kugadzira mushonga une phos-phorus, senge Na 2 Glycerophosphat
Phosphoric acid inonyanya kushandiswa mumishonga, chikafu, fetiraiza uye mamwe maindasitiri, anosanganisira sevanodzivirira ngura, zvinowedzera chikafu, mazino uye orthopedic kuvhiyiwa, EDIC caustics, electrolytes, flux, dispersants, maindasitiri caustics, fetiraiza seyakabikwa uye zvikamu zvekuchenesa imba. zvigadzirwa.Inoshandiswawo semakemikari ejenti, phosphates inovaka muviri kumarudzi ese ehupenyu.
Phosphoric asidhi kana orthophosphoric acid, ine huremu hwemamorekuru hwe97.994, inowanzoitika inorganic acid.Iasidhi yakasimba zviri pakati nepakati.Inowanikwa nekupedza phosphorus pentoxide mumvura inopisa.Orthophosphoric acid inowanikwa mukutengeserana nekurapa apatite ne sulfuric acid.Phosphoric acid inobvisa mvura nyore mumhepo.Kupisa kunorasikirwa nemvura kune pyrophosphoric acid, uyezve inorasikirwa nemvura kune metaphosphate.
Ruzivo rwakawedzerwa:
Nzvimbo yekushandisa:
1. Zvekurima: Phosphoric asidhi ndiyo mbishi yekugadzira yakakosha phosphate fetiraiza (superphosphate, potassium dihydrogen phosphate, nezvimwewo), uyewo mbishi yekugadzira chikafu chekudya (calcium dihydrogen phosphate).
2. Indasitiri: Phosphoric asidhi yakakosha kemikari mbishi zvinhu.Mabasa ayo makuru ndeaya anotevera:
(1) Kubata simbi pamusoro uye kugadzira insoluble phosphate firimu pane simbi pamusoro kudzivirira simbi kubva ngura.
(2) Yakasanganiswa ne nitric acid semushonga wemakemikari kuvandudza kupera kwesimbi.
(3) Kugadzirwa kwe detergent, pesticide raw material phosphate ester.
(4) Raw materials yekugadzira phosphorus-ine flame retardant.
3, chikafu: phosphoric asidhi ndeimwe yezvinowedzera zvekudya, muchikafu seyakavava mumiriri, mbiriso yekudya mumiririri, cola ine phosphoric acid.Phosphates inokoshawo zvokudya zvinowedzera uye zvinogona kushandiswa sezvokudya zvinowedzera.
4, mushonga: phosphoric acid inogona kushandiswa kugadzira phosphate-ine mishonga, yakadai sesodium glycerophosphate, nezvimwewo.
