Hlobo luni lokwelapha okungaphezulu okudingeka kusetshenziselwe i-phosphate? Idlala yiphi indima ngaphambi kokwelashwa?
Hlobo luni lokwelapha okungaphezulu okudingeka kusetshenziselwe i-phosphate? Iyiphi indima eyidlalayo ngaphambi kokwelashwa?,
I-phosphate yaseShayina, I-Hebei phosphate, I-Phosphate, i-phosphate China, umenzi we-phosphate, umphakeli we-phosphate,
1. Ulwazi oluyisisekelo

Ukupakisha: 35Kg imiphongolo yepulasitiki, 300Kg imiphongolo yepulasitiki, ton imiphongolo
2. Izinga lekhwalithi yomkhiqizo
3. Sebenzisa
ezolimo: I-Phosphoric acid iyinto ebalulekile yokwenziwa komanyolo we-phosphate (i-superphosphate, i-potassium dihydrogen phosphate, njll.) ) izinto zokusetshenziswa.
Imboni: I-Phosphoric acid iyi-chemical material eluhlaza, futhi imisebenzi yayo eyinhloko imi kanje:
1. Phatha ingaphezulu lensimbi bese wenza ifilimu ye-phosphate engancibiliki endaweni yensimbi ukuze uvikele insimbi ekugqwaleni.
2. Ihlanganiswe ne-nitric acid njenge-ejenti yokupholisha amakhemikhali ukuze kuthuthukiswe ubushelelezi bendawo yensimbi.
3. I-Phosphateama-esters, izinto zokusetshenziswa zokukhiqiza izinto zokuhlanza nezibulala-zinambuzane.
4. Izinto ezisetshenziswayo zokukhiqiza ama-flame retardants ane-phosphorus
Ukudla: I-Phosphoric acid ingenye yezithako zokudla. Isetshenziswa ekudleni njenge-agent emuncu kanye nesakhi semvubelo. I-Coca-Cola iqukethe i-phosphoric acid.I-Phosphate iyisengezo esibalulekile sokudla futhi ingasetshenziswa njengesithuthukisi somsoco.
Indawo yensimbi "ukwelashwa kwe-phosphorification". Okubizwa ngokuthi i-phosphorus kubhekisela endleleni yokukhiqiza izingcezu zensimbi ngokusebenzisa isixazululo esine-acidic esiqukethe usawoti we-dihydrogen -phosphate, kanye nendlela yokukhiqiza ungqimba oluzinzile lwe-phosphate membrane ebusweni balo ukuze lukhiqize ukusabela kwamakhemikhali. I-membrane ibizwa ngokuthi ifilimu ye-phosphorum. Inhloso eyinhloko yefilimu ye-phosphorum ukukhulisa ukunamathela kwefilimu yokugqoka futhi kuthuthukise ukumelana nokugqwala kokugqoka. Kunezindlela eziningi zokwenza i-phosphorify. Ngokusho kwezinga lokushisa ngesikhathi se-phosphorus, ingahlukaniswa ngokushisa okuphezulu kwe-phosphorus (90-98 ° C), izinga lokushisa eliphakathi kwe-phosphorus (60-75 ° C), i-phosphate lokushisa eliphansi (35-55 ° C) kanye ne-N ekamelweni lokushisa i-phosphorus.
Ubuchwepheshe be-passivation befilimu ye-phosphorum busetshenziswa kabanzi eNyakatho Melika nasemazweni aseYurophu. Ukusetshenziswa kobuchwepheshe be-passivation kusekelwe ezicini zefilimu ye-phosphate ngokwayo. Ifilimu ye-phosphorum incane. Ngokuvamile, i-1-4g/m2, engeqi ku-10g/ M2, indawo yayo yamahhala ye-pore inkulu, futhi ifilimu ngokwayo inokumelana nokugqwala okulinganiselwe. Ezinye zize zibe nokugqwala ngokushesha okuphuzi phakathi nenqubo yokomisa. Ngemuva kwe-phosphorusization, i-passivation kanye nokwelashwa okuvaliwe kungabuye kufakwe i-oxidized ngensimbi evezwe kuma-pores wefilimu ye-phosphorurative, noma ungqimba lwe-passivation lukhiqizwa. Umphumela we-oxidation wenza i-phosphate izinze emkhathini.
Ifilimu yokuguqulwa kwe-phosphate isetshenziswa ku-iron, i-aluminium, i-zinc, i-cadmium, nama-alloys ayo, angasetshenziswa njengongqimba lokugcina olucwengiwe noma njengongqimba oluphakathi kwezinye izendlalelo zokumboza. Indima yayo inalezi zici ezilandelayo.
Nakuba Ukuthuthukisa ifilimu phosphorurative mncane, ngoba ungqimba non-metal non-conductive wokuzihlukanisa, ungakwazi ukuguqula umqhubi omuhle ebusweni bensimbi workpiece ibe umqhubi omubi, ukuvimbela ukwakheka micro -electrical ebusweni i-workpiece yensimbi Ukugqwala kwefilimu yokugqoka. Ithebula 1 libala imiphumela yefilimu ye-phosphate ekumelaneni nokugqwala kwensimbi.
Ukuthuthukisa ifilimu yokunamathisela phakathi kwe-matrix ne-coating noma ezinye izendlalelo zokuhlobisa eziphilayo kuyisakhiwo esiqinile esihlanganisa inhlanganisela eseduze. Awukho umngcele osobala phakathi nenkathi. Izakhiwo ezinama-porous zefilimu ye-phosphorurative zenza i-agent evaliwe, i-coatings, njll ingene kulawa ma-pores, futhi ibophe eduze kwe-membrane ye-phosphoridized, ukuze ithuthukise ukunamathela.
Nikeza indawo ehlanzekile yefilimu ye-phosphorus ingakhula kuphela phezu kwendawo yokusebenza yensimbi ngaphandle kokungcoliswa kwamafutha kanye nongqimba olungagqwali. Ngakho-ke, ama-workpieces ensimbi abe yi-phosphorus anganikeza izindawo ezihlanzekile, ezifanayo, ezingenawo amafutha kanye nezigqwalile.
