2. umgangatho womgangatho wemveliso
3. Sebenzisa
ezolimo: I-Phosphoric acid yinto ebalulekileyo ekrwada yokuveliswa kwezichumisi ze-phosphate (i-superphosphate, i-potassium dihydrogen phosphate, njl.) ) izixhobo eziluhlaza.
Umzi-mveliso: I-Phosphoric acid yimathiriyeli ebalulekileyo ekrwada, kwaye imisebenzi yayo ephambili yile ilandelayo:
1. Phatha umphezulu wesinyithi kwaye wenze ifilimu ye-phosphate enganyibilikiyo kwindawo yesinyithi ukukhusela isinyithi kwi-corrosion.
2. Ixutywe ne-nitric acid njenge-agent ye-chemical polishing ukuze kuphuculwe ukugudiswa kwendawo yesinyithi.
3. Iphosphateii-esters, imathiriyeli ekrwada yokuveliswa kwezicoci kunye nezibulali-zinambuzane.
4. Izinto ezisetyenziswayo zokuvelisa i-phosphorus-containing flame retardants
Ukutya: I-Phosphoric acid yenye yezongezo zokutya. Isetyenziselwa ukutya njenge-agent emuncu kunye nesondlo segwele. I-Coca-Cola iqulethe i-asidi ye-phosphoric.I-Phosphate ikwasisongezo sokutya esibalulekileyo kwaye sinokusetyenziswa njengesixhasi sesondlo.
Umphezulu wesinyithi "unyango lwe-phosphorification". Into ebizwa ngokuba yi-phosphorus ibhekisela kwindlela yokuvelisa i-workpieces yesinyithi ngokusebenzisa isisombululo esine-acidic equlethe ityuwa ye-dihydrogen -phosphate, kunye nendlela yokuvelisa i-membrane ye-phosphate ezinzileyo engapheliyo kumphezulu wayo ukuze ivelise ukusabela kwemichiza. Inwebu ibizwa ngokuba yifilimu yephosphorum. Injongo ephambili yefilimu ye-phosphorum kukunyusa ukunamathela kwefilimu yokugqoka kunye nokuphucula ukuxhathisa kwe-corrosion of the coating. Kukho iindlela ezininzi zokwenza i-phosphorify. Ngokutsho kweqondo lokushisa ngexesha le-phosphorus, inokwahlulwa ibe yi-phosphorus ephezulu (90-98 ° C), i-phosphorus yeqondo eliphakathi (60-75 ° C), i-phosphate yeqondo eliphantsi (35-55 ° C) kunye ne-phosphorus yegumbi le-N.
Itekhnoloji ye-passivation yefilimu ye-phosphorum isetyenziswa kakhulu eMntla Melika nakumazwe aseYurophu. Ukusetyenziswa kweteknoloji ye-passivation isekelwe kwiimpawu zefilimu ye-phosphate ngokwayo. Ifilimu yephosphorum ibhityile. Ngokuqhelekileyo, i-1-4g / m2, engagqithisi i-10g / M2, indawo yayo yamahhala ye-pore inkulu, kwaye ifilimu ngokwayo inokumelana nokugqwala okulinganiselwe. Abanye bade bakhawuleze babe nomhlwa otyheli ngexesha lokumisa. Emva kwe-phosphorusization, i-passivation kunye nonyango oluvaliweyo lunokuqhutyelwa ngakumbi nge-oxidized yintsimbi evezwe kwiipores zefilimu ye-phosphorurative, okanye i-passivation layer yenziwe. Impembelelo ye-oxidation yenza ukuba i-phosphate izinze emoyeni.
Ifilimu yokuguqula i-phosphate isetyenziswe kwintsimbi, i-aluminiyam, i-zinc, i-cadmium, kunye ne-alloys yayo, enokusetyenziswa njengomaleko ococekileyo ogqityiweyo okanye njengomaleko ophakathi kwezinye iileya zokugubungela. Indima yayo inale miba ilandelayo.
Nangona Ukuphucula ifilimu ye-phosphorurative ibhityile, ngenxa yokuba i-non-metal non-conductive isolation layer, inokuguqula i-conductor ecolekileyo yomphezulu we-workpiece yentsimbi ibe ngumqhubi ochaseneyo, inqanda ukubunjwa kwe-micro -electrical phezu komhlaba. umsebenzi wesinyithi Ukonakala kwefilimu yokwambathisa. Itheyibhile 1 idwelisa iziphumo zefilimu ye-phosphate kwi-metal corrosion resistance.
Ukuphucula ifilimu yokubambelela phakathi kwe-matrix kunye nokwaleka okanye ezinye iileyile zokuhombisa eziphilayo sisakhiwo esiqinileyo esidibanisa ukudibanisa okusondeleyo. Akukho mda ucacileyo ngeli xesha. Iimpawu ze-porous zefilimu ye-phosphorurative zenza i-agent evaliweyo, iingubo, njl njl. zingene kule mibhobho, kwaye zibophe ngokusondeleyo kwi-membrane ye-phosphoridized, ukwenzela ukuba kuphuculwe ukunamathela.
Ukubonelela ngefilimu ye-phosphorus ecocekileyo inokukhula kuphela kumphezulu we-workpiece yesinyithi ngaphandle kongcoliseko lweoli kunye nomgangatho ongenamhlwa. Ngoko ke, izixhobo zokusebenza zetsimbi eziye phosphorus zinokubonelela ngeendawo ezicocekileyo, ezifanayo, ezingenamafutha kunye nezinomhlwa.
