Izithasiselo ze-nickel zokushisa okuphezulu
Isengezo se-nickel sokushisa okuphezulu kokucwebezeliswa okuqhubekayo
Inombolo: I-Ni - 3000
instructions
NI-3000 iyisengezo esilungiselelwe ngokukhethekile sokucwecwa okuqhubekayo kwe-nickel sulfonate ku-substrate bese kuba msulwa (ekhanyayo/inkungu ) ithini. Lesi sengezo sivumela ucezu lokusebenza olupuletiwe ukuthi luphumelele izivivinyo zokugeleza kabusha kwezinga lokushisa eliphezulu (IR, ukugeleza kabusha) ngaphandle kokushintsha umbala kwendawo enamathelayo. Izici zayo eziyinhloko kanye nobuhle kufingqiwe kanje:
ilungele ukusetshenziswa enkungu ye-sulfamic acid nickel base/sardines/bright tin process
kulula ukuyisebenzisa, ingadluliswa Ukuhlaziywa kwe-titration elula
ukusebenza kahle kwe-nickel ephezulu, ngaphandle kwesidingo sokushisa okuphezulu
akuphazamisi ukusebenza kwe-nickel plating
foam ephansi
gcina ukushisela okuhle nokubukeka kwe-coating
Izimo zokusebenza:
Ni-3000 kufanele yengezwe enqubweni eqhubekayo ye-nickel sulfonate plating ekuhlanganiseni okungu-1% ngevolumu. Yonke eminye imingcele yokusebenza ye-nickel sulfamate ihlala ifana; Ukuze uthole amanye amapharamitha afanelekile, sicela ubhekisele kudatha yezobuchwepheshe efanele.
Ukwengezwa kwe-NI-3000 kuncike emiphumeleni yenqubo yokubhala titration enamathiselwe ngezansi. Inani elisetshenzisiwe lisekelwe ekuthathweni nasekusetshenzisweni kwe-plating. Inani elingeziwe lilinganiselwa ukuthi licishe libe ngu-0.5L/KAH, kodwa inani langempela eliyisengezo kufanele linqunywe ngokuya ngokusetshenziswa kwangempela.
Ukugxiliswa kwe-Ni-3000 kufanele kugcinwe phakathi kuka-5-20ml/L, kanye nenani elikhulu. kufanele kube ngu-10ml/L. Ukugxila kokusebenza okungaphansi kuka-5 mL/L kuzoholela ekwehleni kokusebenza (ithini lizoshintsha umbala ngemva kokuhlolwa kwezinga lokushisa eliphezulu).
Qaphela: i-NI-3000 inqubo ayikwazi ukusetshenziswa ngaphansi kwesimo sokugxila esingu-20ml/L
Uhlelo lokuhlaziya:
1.0 an ukubuka konke kwe-
1.1 Ukugxila kwesengezo se-Ni-3000 kusixazululo senqubo ye-nickel sulfonate kunganqunywa nge-iodometric titration nesisombululo se-sodium thiosulfate esingu-0.1N.
1.2 Inani elithile lesisombululo esijwayelekile/sokugeza siphawulwe ngenkomba yesitashi.
1.3 Ukugxila kwesithasiselo kubalwa ngenani elikhonjiswe ekuguqukeni ukusuka endaweni eluhlaza okwesibhakabhaka-onsomi ukuya endaweni yokugcina engenambala.
2.0 Izisetshenziswa kanye ne-Instruments
2.1 25 ml graduated cylinder
2.2 Amashubhu okuhlola angu-50ml amabili
2.3 Amabhodlela amabili e-iodine angu-250ml anezitobha
2.4 10ml pipette
3.0 Reagents and materials
3.1 reagent iodine ti1 0.
3.2 0.1N sodium thiosulfate reagent
3.3 isitashi inkomba (entsha)
3.4 Sodium bicarbonate
3 .5 i-glacial acetic acid
4.0 the program
4.1 Ngokusebenzisa isilinda sokulinganisa esingu-25ml, kala amanzi ahlanzekile angu-10ml ube yiflask ye-iodine engu-250ml bese uyimaka "engenalutho"
Utshwala obumhlophe ".
4.2 Sebenzisa i-pipette engu-20ml ukususa u-20.0ml wesisombululo esipholile sokusebenza ku-250ml
ibhodlela le-Iodine, bese ulebula "isixazululo sesampula".
4.3 Yengeza ngokucophelela cishe amagremu angu-2.5 e-sodium bicarbonate ebhodleleni ngalinye, ungawengezi kanye kanye
Kungenjalo , izokhipha ibhamuza ngokushesha. Govuza cishe iminithi elingu-1, i-sodium bicarbonate
Izoncibilika ngokuphelele.
4.4 Engeza u-40.0 mL we-0.1N isixazululo se-iodine ebhodleleni lesampula, xuba ngokushesha bese umisa ibhodlela. leave
Linganisa ivolumu ye-iodine engeziwe bese uyirekhoda njengokuthi V1
4.5 Engeza u-40.0 mL we-iodine engu-0.1N ebhodleleni elingenalutho bese ubhala ngokuthi V2
4.6 Beka womabili amabhodlela ebumnyameni ihora elilodwa ukuze vumela ukusabela okugcwele.
4.7 Ngemva kwehora elingu-1, ngeza kancane u-25 mL i-acetic acid ebhodleleni elibhalwe ukuthi "isixazululo sesampula". 0.1N i-sodium thiosulfate iye endaweni yokugcina engenambala.
4.9 Rekhoda umthamo we-0.1N sodium thiosulfate esetshenzisiwe -- V3.
4.10 Isixazululo esibhalwe ukuthi "blank" ebhodleleni, phinda u-4.6 kuya ku-4.8 bese urekhoda njenge-V4 .
5.0 calculation
Ukugxila kwe-Ni-3000 kubalwe kanje:
Ni - 3000 (ml/L) = {[(V1 (N1) (N2 (V3)]] - [((V2) (N1) (N2) (V4) x 50
