Izengezo ze-nickel zePearl
Ni-351 nickel sealing additives
(1) Izici :
1. Ifaneleka ngokukhethekile inqubo yokuhlanganisa i-nickel enezingqimba eziningi esebenza ngokuqinile ngokumelene nokugqwala.
2. Iqukethe inani le-conductive particulate additive ayisatshalaliswa ngokufanayo kungqimba lwe-nickel ekhanyayo, (. . 3 million noma ngaphezulu izimbotshana / cm), ukuze ungqimba lwe-chromium lwakheke ku-chromium enezimbotshana, ngaleyo ndlela kuthuthukiswe ukumelana nokugqwala.@ _@3. Isixazululo sokucwenga sinokuzinza okuphezulu, umjikelezo omude wokwelapha, ukusebenza okulula, futhi singanciphisa kakhulu ukujiya kokunamathela ngaphansi kwezidingo ezifanayo zokusebenza kokugqwala.

(3 ) Ukulungiswa kwesixazululo |
1. Thela izingxenye ezimbili kwezintathu zamanzi ethangini eliyisipele (noma ithangi lokuqala) bese ulishisa libe ngu-66 ℃.
2. Engeza i-nickel sulfate edingekayo ne-nickel chloride, gxuma ukuze uhlakaze ngokuphelele.
3. Noma i-nickel carbonate yengezwe isixazululo esingu-4% se-sodium hydroxide ukuze kulungiswe i-pH (inani elingu-PH) libe ngu-5.2 .
4. Engeza i-2.5 ml / l ye-hydrogen peroxide, ehlanjululwe ngamanzi ngaphambi kokwengeza inombolo encane yesikhathi sokugqugquzela.
5. Engeza u-2.5 g/L wekhabhoni ecushiwe, gudluza amahora ambalwa, bese uyiyeka ime ubusuku bonke.
6. Sebenzisa iphampu yokuhlunga ukuze uhlunge isixazululo se-plating ethangini lokucwenga elihlanzekile.
7. Engeza i-boric acid edingekayo, uyihlakaze ngamanzi ashisayo, futhi ugcine ithangi linyakaza ukuze liqedwe ngokuphelele.
8. Engeza i-sulfuric acid ehlanjululwe futhi ulungise inani le-pH libe ngu-3.8-4.5.
9. Sebenzisa i-cathode enothayela kanye nokuminyana kwamanje okuphansi (0.15-0.4 ampere/dm2) ukuze uthole ugesi oqhubekayo amahora angaphezu kwangu-12, kuze kube yilapho umbala weleveli ephansi webhodi likathayela ushintsha usuka kumnyama omnyama ukuya kuyunifomu empunga ngokukhanyayo noma emhlophe.
10. Ngemva kokwengeza izithasiselo ze-Ni-351 ezingenhla, ungaqala ukufaka i-trial plating.
(4) Umsebenzi wezinto ezingavuthiwe
Nickel Sulfate
| Nickel sulfate wumthombo oyinhloko wama-ion e-nickel, futhi nickel yensimbi efakwa izingxenye ezicwebezelayo zincishiswa ngama-nickel ion. |
Nickel chloride |
||
| I-Nickel chloride inikeza ama-ion e-chloride ukusiza i-anode incibilike, inciphise ukuhlukaniswa kwe-anode, ikhulise ukuqhutshwa kwesisombululo se-plating, futhi yenze i-cathode ibe nokuminyana okuphezulu kwamanje, kuyilapho ihlinzeka nama-nickel ions. |
Boron acid |
||
| Ukugcwala kwe-boric acid kubalulekile ekugcineni i-pH, ukunamathela okufanayo, ukunamathela kanye nokuthamba. Akufanele kube ngaphansi kuka-40 amagremu. I-boric acid yengezwa ngemva kokuphela kosuku lomsebenzi ngesisekelo sokuhlaziya ngenxa yokusetshenziswa kwayo. |
(5) Ukugcinwa kwesixazululo |
||
Microporous nickel, ngenxa yokwethulwa kwama-hydroxide radicals nokungcola okuhlukahlukene okumuncwa izinhlayiya eziqinile, futhi ukunqwabelana kancane kancane kwe-anode slime, kuzolimaza ukusebenza kwesisombululo sokucwenga. Njengesixazululo esikhanyayo se-nickel plating, ngemva kwesikhathi sokukhiqiza, ukwelashwa okukhulu kuyadingeka. Kodwa-ke, i-nickel ekhanyayo enezimbobo ze-nickel inendawo yayo ekhethekile, i-chrome plating encane kakhulu (imizuzu engu-1-3), ngakho-ke, uma ukugeza okungcolile komshini (ububanzi obukhulu) ngeke kufakwe ku-workpiece , Ukwakheka kwezinhlayiya eziqinile. . Ngakolunye uhlangothi, izikhwama ze-anode azikwazi ukusetshenziselwa ama-anode e-nickel microporous, ukuze izinhlayiya eziqinile zihlakazeke kangcono kwisisombululo se-plating, kodwa ithuba lodaka lwe-nickel anode olungena kubhavu luyanda. Izinhlayiya nokungcola okusemishinini kucwila phansi ethangini, kukhishwe uketshezi olucacile, bese kufakwa i-hydrogen peroxide ne-activated carbon oketshezini olucacile ukuze lwelashwe. (Indlela efanayo nokwelashwa kwe-nickel egqamile) Bese wengeza izithasiselo ezahlukahlukene ngokuya ngenani lefomula, lungisa inani le-pH, bese uqhubeka nokukhiqiza. Lahla izinhlayiya eziqinile, izinhlayiya zemishini nodaka lwe-anode ngaphansi kwethangi.
Isixazululo se-Nickel Microporous plating sinenani elivumelekile elivumelekile lokungcola njenge-nickel ekhanyayo. Ukungcoliswa kokungcola kwensimbi enzima nakho kungasuswa yi-electrolysis yamanje ephansi.
Kumelwe kugcizelelwe ukuthi ukwethulwa kokungcola kwezinto eziphilayo kuzonciphisa kakhulu ukuminyana kwama-micropores. Ngakho-ke, izinto zokusetshenziswa zokulungiselela ukugeza okusha kufanele zinake okuqukethwe kokungcola okuphilayo. Ama-hydrocarbon angagcwalisiwe, ama-pyridine, nama-epoxy condensate alethwa kusixazululo esikhanyayo se-nickel plating njengezikhanyisi futhi anomthelela omncane ku-nickel encane. Ukwethulwa kwe-ejenti yokumanzisa ku-nickel ekhanyayo akuthinti ukuminyana kwe-micropore nokubukeka. Ngakho-ke, kungabhekwa njengokushintsha ngokuqondile kusuka ku-nickel ekhanyayo kuya ku-nickel encane ngaphandle kokuwasha phakathi. phansi kwethangi. Lapho ukukhiqizwa kuqaliswa kabusha, ukunyakaziswa komoya kufanele kwenziwe cishe amahora angu-1-2, futhi izinhlayiya zinganyakaziswa ngokuphelele ngaphambi kokuba kuqale ukukhiqizwa. zelashwa kanye kuphela ngemva kwesigamu sonyaka, futhi kuba nokwehluleka okumbalwa .
Ngemva kokuhlola nokuqongelela ulwazi ekukhiqizeni izimboni eziningi , ukusetshenziswa kwezithasiselo ezihlukahlukene kungokulandelayo:
Ni-351 A
Right inani
Ni-351 B
| Inani elilungile |
Ni-351 C (i-additive) |
| 400-500 ml / kA ngehora |
Ni-351 D |
| 200-300 ml / kA ngehora |
Inqobo nje uma ukusetshenziswa okungenhla kungeziwe, ukubukeka kwe-coating kanye nokuminyana kwezinhlayiyana ezanele kungaqinisekiswa. |
| (6) Isexwayiso sokuphepha: |
Bigley incoma ukuthi ufunde imininingwane yokuphepha yalokhu. umkhiqizo ngaphambi kokusebenzisa lo mkhiqizo. Iphepha ledatha elibalulekile lokuphepha lingatholwa enkampanini. |
