Ndeupi rudzi rwekurapa kwepamusoro kunoda kushandiswa kune phosphate?Inoita basa rei usati warapwa?,
Chinese phosphate, Hebei phosphate, Phosphate, phosphate China, phosphate mugadziri, phosphate mutengesi,
1. Ruzivo rwekutanga
Molecular formula: H3PO4

CAS NO: 7664-38-2
Kukwanisa kugadzira: 10,000 matani / gore
Packaging: 35Kg epurasitiki mbiya, 300Kg epurasitiki mbiya, tani mbiya
2. Chigadzirwa chemhando yepamusoro
3. Shandisa
zvekurima: Phosphoric asidhi chinhu chakakosha mbishi kugadzirwa kwefosfate fertilizer (superphosphate, potassium dihydrogen phosphate, etc.) ) mbishi.
Indasitiri: Phosphoric acid yakakosha kemikari yakabikwa, uye mabasa ayo makuru ndeaya anotevera:
1. Bata simbi pamusoro uye gadzira insoluble phosphate firimu pamusoro pesimbi pamusoro kudzivirira simbi kubva ngura.
2. Yakasanganiswa ne nitric acid sekemikari yekuchenesa makemikari kuvandudza kutsetseka kwesimbi.
3. Phosphateesters, mbishi zvinhu zvekugadzira detergent nemishonga yezvipembenene.
4. Raw zvinhu zvekugadzira phosphorus-ine flame retardants
Zvokudya: Phosphoric acid ndeimwe yezvinowedzera zvekudya.Inoshandiswa muchikafu sechinhu chinovava uye mbiriso inovaka muviri.Coca-Cola ine phosphoric acid.Phosphate zvakare yakakosha chikafu chekuwedzera uye inogona kushandiswa sechikafu chinowedzera.
Iyo metal surface "phosphorification treatment".Iyo inonzi phosphorus inoreva nzira yekugadzira simbi workpieces kuburikidza neine acidic mhinduro ine dihydrogen -phosphate munyu, uye nzira yekugadzira yakagadzikana insoluble insoluble phosphate membrane layer pachiso chayo kugadzira kemikari.Iyo membrane inonzi phosphorum film.Chinangwa chikuru chemufirimu wephosphorum ndechekuwedzera kusungirirwa kwefirimu yekuputira uye kuvandudza kusagadzikana kwekuora kwekuputira.Kune nzira dzakawanda dzekuita phosphoric.Maererano nekushisa panguva ye phosphorusization, inogona kukamurwa kuva yakakwirira tembiricha phosphorus (90-98 ° C), yepakati tembiricha phosphorus (60-75 ° C), yakaderera tembiricha phosphate (35-55 ° C) uye N mukamuri tembiricha phosphorus.
Iyo passivation tekinoroji yefirimu yephosphorum inoshandiswa zvakanyanya muNorth America nenyika dzeEurope.Iko kushandiswa kwepassivation tekinoroji kunobva pane maitiro eiyo phosphate film pachayo.Iyo phosphorum firimu itete.Kazhinji, iri 1-4g/m2, isingapfuure 10g/ M2, nzvimbo yayo yemahara yepore yakakura, uye iyo firimu pachayo ine kushomeka kushoma.Vamwe vanotokurumidza kuita ngura yero panguva yekuomesa.Mushure me phosphorusization, kurapa uye kuvharika kurapwa kunogona kuwedzera oxidized nesimbi yakafumurwa mumapores eiyo phosphorurative firimu, kana iyo passivation layer inogadzirwa.Iyo oxidation effect inoita kuti phosphate igadzikane mumhepo.
Iyo phosphate inoshandura firimu inoshandiswa musimbi, aruminiyamu, zingi, cadmium, uye alloys ayo, ayo anogona kushandiswa seyekupedzisira akacheneswa layer kana seyepakati pemamwe mazinga ekuvhara.Basa rayo rine zvinhu zvinotevera.
Kunyangwe Kuvandudza iyo phosphorurative firimu yakatetepa, nekuti isiri-simbi isina-conductive isolation layer, inogona kushandura yakanaka conductor yepasi pesimbi workpiece kuita adverse conductor, inhibisa kuumbwa kweiyo micro-electrical pamusoro pe. iyo simbi workpiece Corrosion yekuvhara firimu.Tafura 1 inonyora zvinokonzeresa phosphate film pane simbi corrosion resistance.
Kuvandudza iyo adhesion firimu pakati pematrix uye yekupfekedza kana mamwe organic ekushongedza akaturikidzana ndeye yakasimba yakazara chimiro chinosanganisa kusanganisa kwepedyo.Hapana muganhu uri pachena panguva iyi.Iyo porous properties ye phosphorurative firimu inoita kuti iyo yakavharwa mumiririri, majasi, nezvimwewo zvipinde mukati mezviputi izvi, uye zvakanyatsosunga kune membrane phosphoridized, kuitira kuti ivandudze kunamatira.
Ipa yakachena pamusoro phosphorus firimu anogona chete kukura pamusoro pemvura simbi workpiece pasina mafuta kusvibiswa uye ngura-isina layer.Naizvozvo, simbi workpieces anga ari phosphorus anogona kupa yakachena, yunifomu, mafuta-isina uye ngura nzvimbo.
