Chikafu Giredhi kana Industrial giredhi: Ndeipi kushandiswa kwephosphoric acid?Tarisa pazvinhu zvitanhatu izvi uye uchanzwisisa
Chikafu Giredhi kana Industrial giredhi: Ndeipi kushandiswa kwephosphoric acid?Tarisa aya mapoinzi matanhatu uye iwe unonzwisisa,
Phosphoric acid, PHOSPHORIC ACID vagadziri, phosphoric acid vatengesi, kushandiswa kwe phosphoric acid,
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
Muindasitiri yemakemikari, phosphoric asidhi chinhu chakakosha zvinhu, asi kutaura zvazviri, phosphoric asidhi zvakare yakawanda inoda kunzwisisa mutsauko!Semuenzaniso, ndeupi musiyano uripo pakati pegiredhi rekudya uye giredhi giredhi phosphoric acid mukushandisa maitiro?
Zvemukati zvechikafu uye maindasitiri giredhi phosphoric acid inosvika 85% uye 75%.Indasitiri giredhi phosphoric acid inonyanya kushandiswa muindasitiri yemakemikari, kusanganisira kudhinda machira, kugeza kugadzirwa, matanda refractories, metallurgy uye mamwe maindasitiri esimbi;Chikafu-giredhi phosphoric acid inogona kushandiswa mukunakisa chikafu chemazuva ese senge zvigadzirwa zvemukaka, kubika waini, shuga nemafuta ekubikisa.
Ndeapi mashandisirwo makuru egiredhi rekudya phosphoric acid?
1. Inogona kushandiswa sechikafu chekuwedzera, zvakadai se citric malic acid uye mamwe maasidhi anonhuwira, uye inoita basa rayo sechinhu chisina kuchena chembiriso uye phosphate mukubika.
2. Vanoda waini havafaniri kuva vatorwa kune phosphoric acid!Paunenge uchibika, phosphoric acid inogona kupa hutano hwakagadzikana kune mbiriso, iyo inodzivirira kukura kwebhakitiriya inorasika;Mukugadzira doro, inogona zvakare kuita basa rakanaka relactic acid kugadzirisa kukosha kwePH!
3. Zviwanikwa zvemvura zvino zvakakosha zvakanyanya, uye phosphoric acid inogonawo kushandiswa sechinhu chakabikwa chechikamu chekuchenesa chiyero uye zvinopfavisa mvura, zvichitipa mvura yakachena.
Industrial giredhi phosphoric acid yakanyanya kuoma, asi zvakare inoshandiswa zvakanyanya:
1. Phosphoric asidhi inofanira kuva nenzvimbo muindasitiri yesimbi.Kana iwe uchida kugadzira simbi pamusoro pekugadzira uye kushandisa yakatsetseka uye yakanaka, phosphoric acid inofanirwa kuve yakakosha.Kana ikasangana nesimbi, inogona kubatsira pamusoro pemvura insoluble phosphate film, kunyange mubasa rinotevera, kuderedza mukana wesimbi corrosion.
2. Kukwanisa kuchenesa kwephosphoric acid kunoregererwa nevanhu vakawanda.Muindasitiri yekudhinda, inogona kushandiswa mumvura yekuchenesa kuti ibatsire kubvisa mavara paplate yeoffset zvakanyanya, uye inogonawo kuve chikamu chezvinosuwisa muindasitiri yemakemikari yemazuva ese!
3. Pamusoro pezvo, ine zvakare nzvimbo yayo mukuvandudza hupenyu hwesevhisi yechoto, bhatiri electrolytes uye kunyange kushandiswa kazhinji kwezvigadzirwa zvekuchengetedza ganda uye zvizorwa.
