Imikhiqizo
I-Crivalent chromium zinc passivator
I-Trivalent chromium color zinc water Zn-237
Zn-237 iyisistimu ye-trivalent ye-chromium passivation yombala esetshenziswa ungqimba olunothayela. I-coating inokumelana nokugqwala okuphezulu futhi ayinawo ama-organic acid. Ngenqubo yokucwilisa elula, umkhiqizo ungagqama ngendlela efanayo, umbala ojulile ube ifilimu ye-passivation ephuzi enamandla enamandla okubopha i-chromium.
Isici
1. I-Zn-237 A ne-Zn-237 C ingathola umbala ofanayo nowe-hexavalent chromium passivation.
2. Ayiqukethe i-chromium ene-hexavalent.
3. Emazingeni okushisa asekamelweni, kukhiqizwa umfaniswano kanye nefilimu ye-passivation egqamile.
4. Ukumelana nesifutho sikasawoti songqimba lwe-passivation lwe-Zn-237 kungcono kunosendlalelo esinehexavalent se-chromium passivation.
5. Okokusebenza nobuchwepheshe bokudlula kwe-chromium eyi-hexavalent kungasetshenziswa.
6. Ezingeni lokushisa legumbi, kukhiqizwa ungqimba oluyisivikelo olunombala ophuzi olujiyile.
Advantage
1.Zn-237 A lungasetshenziswa njengengxenye ehlukile, futhi isikhathi esincane sokuhlola isifutho sikasawoti amahora angu-150.
2. Engeza i-Zn-237 C enanini lika-5-20 ml/litre , futhi umbala wokumboza ungaba mnyama.
Ukugeleza kwenqubo:
Galvanizing → ukuwasha ngamanzi → 0.5% nitric acid → ukuwashwa kwamanzi → Zn-237 → ukuwasha → drying

Qaphela: Kunconywa ukusebenzisa Zn-237 B ( liquid) ekudluleni kwezingubo eziwugqinsi ezinombala ojulile . I-Zn-237 B idlala indima esobala ekufakweni kwemiphongolo .
Indlela Yokulawula:
Hlaziya njalo ukungezwa kwe-Zn-237 bese uhlanza i-nitric acid, i-sodium bicarbonate noma i-sodium carbonate ukuze ulungise inani le-pH.
Gcwalisa ngokuvumelana endaweni yokusebenza engashintshiwe, ngemva komsebenzi ongu-100 dm² (10 ft²), engeza u-30-35 ml Zn-237 A. Zn-237 kuncike ekulahlekelweni okwenziwayo.
Ukuhlaziya
Zn-237 okuqukethwe
1) Thatha u-2 ml wesisombululo se-Zn-237 sokucwenga ube yi-250 ml ye-conical flask.
2) Faka u-50 ml wamanzi ahlanzekile.
3) Lungisa i-pH ibe yi-10 (engeza u-10-15 ml we-10 % sodium hydroxide, ikhambi liphenduka libe luhlaza).
4) Faka u-1.0-1.5 ml we-hydrogen peroxide.
5) Bilisa ikhambi imizuzu engama-30-45 kuze kube yilapho umthamo woketshezi uncipha ube ngu-1/3, futhi i-hydrogen peroxide eyeqile iyahwamuka.
6) Engeza u-100 ml wamanzi ahlanzekile ukuze uhlambulule isisombululo sokupholisa.
7) Ifakwe nge-concentrated hydrochloric acid (15ml), umbala wekhambi ushintshile usuka ophuzi ube owolintshi. Ingase ishise, bese iphola.
8) Engeza u-4-5 ml wesisombululo se-potassium iodide engu-10% (okubomvu okumnyama), bese wengeza isixazululo sesitashi.
9) Titrate ngesisombululo se-sodium thiosulfate esingu-0.1 esilinganayo kuze kube umbala omnyama. iyanyamalala.
Indlela yokubala
Zn-237 (%)= titration reading×N×16.7
Inothi lokusebenza:
1.Amanzi ompompi noma amanzi ahlanzekile angasetshenziswa ukuvula ithange.
2.I-passivation effect izoba ngcono uma umoya usetshenziselwa ukunyakazisa kancane noma izingxenye zokucwenga zinyakaziswa futhi zinyakaziswa.
3.Izinga lokushisa lomjikelezo wokomisa alidluli ku-120°C.
4.I-workpiece okuwele esixazululweni sokucwenga kufanele kukhishwe ngokushesha, ngaphandle kwalokho impilo yesixazululo sokucwenga izothinteka.
5.Impahla yolwelwesi yethangi lokucwenga kufanele kube i-polyvinyl chloride noma irabha.
