I-ejenti yokwehlisa ukugqwala kwe-alkali

Incazelo :

BC-20 iyinhlanganisela ye-alkaline eklanyelwe ngokukhethekile ukuhlanza nokuluma i-aluminium. Ihlinzeka ngokuluma okuhle kokupholisha okulandelayo, i-anode noma izinqubo zokumboza nge-chrome.

BC-20 inezimpawu ezine ezisobala: 1 ) ukulunywa okukhulu kakhulu; 2 ) hhayi amabhamuza amaningi kakhulu; 3) asikho isifutho se-alkaline; 4 ) akukho ukunqwabelana kodaka noma izinsalela.

Izici kanye nezinzuzo :

1. Igwebu eliphansi

1. Ngesikhathi sokuluma, asikho isifutho se-lye, ngakho izimo zokusebenza zimihle;

1. Iqeda ukuluma noma ukuvuza okungavamile okubangelwa amabala kawoyela noma ukuvinjwa kwendawo kwefilimu;

1. Umthelela ofanayo wokuluma futhi omuhle, oqinisekisa ikhwalithi;

1. Ayikho idiphozithi yodaka ngaphansi noma odongeni lwethangi, futhi izindleko zokuwulungisa ziphansi;

1. Susa amabala kawoyela ngokushesha nangokuphelele, ukuhambahamba kalula, ukusebenza okunezindleko eziphansi;

1. Ihlinzeka ngokusika okungaphansi kwe-aluminiyamu yokuhlobisa .

Izakhiwo zemvelo namakhemikhali:

I-alkaline

BC-20 i-alkaline etching agent elinganiselayo enganikeza ukugqwala okufanayo nokuluma okuhle ngesikhathi esifushane.

Ikhono lokuhlanza

Nakuba i-BC-20 inekhono elihle lokususa amabala kawoyela, ukuhlanza ngaphambili kuyadingeka ezimweni eziningi ukuqinisekisa ukuluma okufanayo. Inani lensimbi eqoshiwe lingalawulwa izimo zokusebenza ezifana nezinga lokushisa, isikhathi, nokugxilisa ingqondo.

Ukuze uqinisekise ukuluma okufanayo, izinga lokushisa, isikhathi nokugxilisa ingqondo kufanele kuhlale njalo.

Izici zegwebu

Igwebu okukhiqizwa ngesikhathi sokuluma kuyanyamalala ngokushesha ngemva kokuba ucezu lokusebenza lushiye isisombululo.

Izimo zokusebenza :

concentration

15-120 g/L

izinga lokushisa

50-93 ° C

isikhathi

30 ~3 amaminithi noma ngaphezulu

imishini

Ithangi lensimbi ne-heater

Inqubo yomjikelezo :

1.BC -19

1. Geza ngamanzi abandayo

1.BC-20

1. Ukugeza okubandayo

1. Khipha i-oxide noma ukungcola

1. Ukugeza okubandayo

1. Ukomisa, ukupholisha ngamakhemikhali, ukupholisha nge-electrolytic, i-electroplating noma i-anodizing treatment.

Izinyathelo zokuhlaziya :

BC-20 indlela yokuhlaziya

Ukuhlaziywa kwe-aluminium etchant

(A) 1. Sebenzisa i-pipette ukudlulisa ama-10 ml okubanda BC-20 ku-250 ml ye-conical flask;

2. Engeza cishe u-50 ml wamanzi ahlanzekile kanye namaconsi angu-3-5 e-phenolphthalein ekhombisa i-ejenti;

3. Titrate ngo-0.5N HCI kuze kunyamalale umbala ophinki;

4. Rekhoda inombolo ye-ml edliwe ngu 0.5N HCI titration .

(B) 1. Engeza u-30 mls wesixazululo se-KF esingu-10%. Uma umbala ophinki ungasaveli , kune - aluminium engancibilikisiwe kubhavu . Sebenzisa indlela yokubala 2.

2. Uma umbala ophinki uvela, setha kabusha i-burette ibe uziro futhi i-titrate ngo-0.5N HCI kuze kunyamalale umbala ophinki.

3. Phinda izinyathelo B 1 kanye no-B 2 ( ngaphandle kokumisa uziro). Uma umbala obomvana ungabonakali phakathi nemizuzwana engama-30, akukho okunye ukushintshwa kwe-titration okudingekayo. Uma u-pink evela, qhubeka u-titrating. Rekhoda i-0.5N HCI ml edliwe esinyathelweni B sokulinganisa .

Isibalo :

1. BC-20 concentration (oz/gal) = ( ml inombolo esinyathelweni A titration x 0.42)-( inombolo ml esinyathelweni B x 0.15)

1. I-aluminium encibilikisiwe (g/L) = inombolo ye-ml efakwe titrated esinyathelweni B x 0.45

1. I-aluminiyamu e-sodium (oz/gal) = i-aluminium encibilikisiwe (oz/gal) x 3.04
