2. Heerka tayada alaabta

3. Isticmaal
beeraha: Phosphoric acid waa walxo ceeriin ah oo muhiim u ah soo saarista bacriminta fosfatetada (superphosphate, potassium dihydrogen phosphate, iwm) ) alaabta ceeriin.
Warshadaha: Phosphoric acid waa walxo kiimiko ah oo ceeriin ah oo muhiim ah, shaqadeeda ugu muhiimsanna waa sidan soo socota.
1. daaw birta oogada oo samee filim fosfateed aan milmi karin oogada birta si aad birta uga ilaaliso daxalka.
2. Lagu qaso aashitada nitric sida walax kiimiko ah oo dhalaalaysa si loo hagaajiyo jilicsanaanta dusha birta.
3. Fosfateesters, alaabta ceeriin ee soo saarista saabuunta iyo sunta cayayaanka.
4. Qalab ceeriin ah oo loogu talagalay soo saarista fosfooraska ka kooban ololka
Cuntada: Phosphoric acid waa mid ka mid ah cuntooyinka lagu daro. Waxaa loo isticmaalaa cuntada sida wakiilka dhanaan iyo nafaqeynta khamiirka. Coca-cola waxay ka kooban tahay fosfooraska acid.Phosphate sidoo kale waa wax lagu daro cuntada oo muhiim ah waxaana loo isticmaali karaa kobciye nafaqo.
Dusha birta ah "daaweynta fosfooraska". Fosfooraska waxa loogu yeero waxaa loola jeedaa habka loo dhaliyo workpieces biraha iyada oo loo marayo xal acidic ka kooban dihydrogen -phosphate cusbo, iyo hab ka mid ah soo saarida lakabka phosphate fosfooraska xasilloon oo aan la milmay on dusha sare si ay u abuuraan falcelin kiimikaad. Xuubka waxaa loo yaqaan filim fosfooraska. Ujeedada ugu weyn ee filimka fosfooraska waa in la kordhiyo adhesion ee filimka daahan iyo hagaajinta caabbinta daxalka ee daahan. Waxaa jira siyaabo badan oo fosfooraska loo sameeyo. Marka loo eego heerkulka inta lagu jiro fosfooraska, waxaa loo qaybin karaa fosfooraska heerkul sarreeya (90-98 ° C), fosfooraska heerkulka dhexdhexaadka ah (60-75 ° C), fosfooraska heerkulka hooseeya (35-55 ° C) iyo fosfooraska heerkulka qolka N.
Tiknoolajiyada gudbinta ee filimka fosfooraska ayaa si weyn looga isticmaalaa Waqooyiga Ameerika iyo wadamada Yurub. Isticmaalka tignoolajiyada passivation waxay ku salaysan tahay sifooyinka filimka fosfatka laftiisa. Filimka fosfooraska waa dhuuban. Guud ahaan, waa 1-4g/m2, taas oo aan ka badnayn 10g/M2, aagga daloolka xorta ah waa weyn yahay, filimka laftiisa ayaa leh iska caabin xaddidan. Qaar baa xitaa si degdeg ah u yeesha miridh jaale ah inta lagu jiro habka qalajinta. Ka dib fosfooraska ka dib, daawaynta iyo daawaynta xiran waxaa lagu sii kordhin karaa oksaydh by birta soo bandhigtay daloolada filimka fosfooraska, ama lakabka passivation ayaa la soo saaray. Saamaynta oksaydhisku waxay ka dhigtaa fosfattu inay dejiso jawiga.

Filimka beddelka fosfooraska waxaa loo isticmaalaa birta, aluminium, zinc, cadmium, iyo alliyaheeda, kuwaas oo loo isticmaali karo lakabka ugu dambeeya ee la safeeyey ama lakabka dhexe ee lakabyada kale ee daboolka. Doorkeedu wuxuu leeyahay dhinacyadan soo socda.

Inkasta oo Hagaajinta filimka fosfooraska waa khafiif ah, sababtoo ah waa lakabka go'doominta non-metal non-conductive, waxay u beddeli kartaa kaari ganaax dusha workpiece biraha galay kaari xun, xannibi formation of koronto-korodh dushiisa workpiece biraha Daxalka filimka daahan. Jadwalka 1 wuxuu taxayaa saamaynta filimka fosfooraska ee iska caabbinta daxalka birta.
Hagaajinta filimka adhesion ee u dhexeeya matrixka iyo daboolka ama lakabyada kale ee qurxinta organic waa qaab-dhismeed guud oo adag oo isku dhafan oo isku dhafan. Ma jiro xuduud cad inta lagu jiro muddada. Qalabka dabada leh ee filimka fosfooraska ayaa ka dhigaya wakiilka xiran, dahaarka, iwm. waxay galaan daloolladaas, waxayna si dhow ugu xiraan xuubka fosfooraska, si loo hagaajiyo adhesion.

Bixi filimka fosfooraska dusha nadiif ah oo keliya koraan karaa on dusha workpiece biraha aan wasakhaysan saliid iyo miridhku -free lakabka. Sidaa darteed, biraha birta ah ee fosfooraska ah waxay ku siin karaan nadiif, lebbis, dufan-free iyo dusha daxalaysan.
