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.

Shandisa:
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.Material ye phosphatide iyo inoshandiswa kugadzira chigadzirwa chekugeza uye chezvipembenene
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
Chikafu uye maindasitiri giredhi phosphoric acid zvinhu zviviri zvakakosha zvemakemikari zvinowanzoshandiswa munzvimbo dzakasiyana siyana. Ndeipi misiyano pakati pavo panguva yekushandiswa, uye unowana sei nzvimbo yakakodzera.
1. Chikafu chegiredhi phosphoric acid
Chikafu giredhi phosphoric acid ikristaro isina ruvara, inoonekera kana zvishoma yero ine yakasimba acidity uye adsorption zvimiro. Inogona kuita nesimbi ions kugadzira insoluble phosphates, uye saka inoshandiswa zvakanyanya muchikafuindustry. Hunhu hwakagadzikana, husina ngozi kumuviri wemunhu.
2. Industrial giredhi phosphoric acid
Industrial giredhi phosphoric acid inoparadza uye ine acidic. Kuchena kwemaindasitiri giredhi phosphoric acid yakadzikira, asi ine yakanaka catalytic chiitiko uye kugadzikana, uye inoshandiswa zvakanyanya muminda yakadai semakemikari engineering, simbi, uye kurapwa kwemvura.
Mukuita kwekushandisa, chiyero chekushandiswa kwezviviri zvakare hachina kunyatsoenderana. Semuyenzaniso, chikafu giredhi phosphoric asidhi inowanzoshandiswa acidity mumiririri inogona kuwedzera acidity yechikafu uye kunatsiridza kuravira kwayo. Semuenzaniso, kuwedzera huwandu hwakakodzera hwegiredhi yefosphoric acid yechikafu kune zvigadzirwa zvakaita sezvinwiwa, zvihwitsi, uye macondiments zvinogona kuvapa kuravira kwakasiyana.
Chechipiri, inogona kushanda sebuffer kuchengetedza kutsva uye kuravira kwechikafu. Kuwedzera chikafu giredhi phosphoric acid kune zvigadzirwa zvakaita seyogati uye jamu zvinogona kudzivirira kupera kwechikafu. Inogonawo kuita nesimbi ions muchikafu kugadzira insoluble phosphates, nekudaro ichidzikisa zviri mukati mesimbi inorema muchikafu.
Industrial giredhi phosphoric acid inoshandiswa zvakanyanya muindasitiri yemakemikari, senge mukugadzira phosphatefetereza, mishonga yezvipembenene, dhayi, etc. Mukuwedzera, maindasitiri giredhi phosphoric asidhi inogonawo kushandiswa semurazvo retardant, dehydrating agent, catalyst, nezvimwe.
Inoita basa rakakosha mumunda wemetallurgical, senge mukupenya, kubvisa ngura, kugeza acid, nezvimwe zvesimbi. Pamusoro pezvo, maindasitiri giredhi phosphoric acid inogona zvakare kushandiswa kubvisa simbi, senge lead, tin, nezvimwe kubva mumabhatiri emarara. Iine mashandisirwo akasiyana-siyana mumunda wekurapa kwemvura, iyo inogona kunyatsobvisa yakamiswa yakasimba, sediments, uye microorganisms mumvura, nekuvandudza mvura.
Nekuwedzera kuri kuramba kuchienderera mberi kweminda yekushandisa yechikafu uye maindasitiri giredhi phosphoric acid, kudiwa kwemusika kuri kuwedzera gore negore. Iko kudiwa kwemusika kwemaindasitiri giredhi phosphoric acid ine tarisiro yakakura, uye kukwidziridzwa kwekushandisa kwehutano, girinhi, uye yemhando yepamusoro chikafu kwakapawo mikana mitsva yemusika wegiredhi phosphoric acid.
Muchidimbu, chikafu uye maindasitiri giredhi phosphoric acid zvine tarisiro yakafara yekushandiswa munzvimbo dzakasiyana siyana. Kupesana nemamiriro ekuwedzera kudiwa kwemusika, mabhizinesi anofanirwa kugara achigadzira uye kugadzirisa mhando kuti asangane nemusika zvinodiwa! Kana zvichidikanwa, ndapota inzwa wakasununguka kubata uye kutaurirana.
