Chromium durum additivorum
CR-2 magnum efficientiam dura chromium additivorum
1. Features@___@ Catholica efficacia hodiernae usque ad 2 . 4 ad 26%, norma conventionalis est chrome plating processum 2-3 temporibus, industria conservationis.
2. Utere densitate currenti lata, 2 0- . 6 0A / d㎡ potest, depositio celeritatis.@___@3. Nulla fluoride, nulla corrosio ad densitatem depressam in area substrati, nulla corrosio ad anode.
4. Microhardentia liturae attingere potest 1000-1100KHN 100
5. Platemen stratum lucidum, laeve, subtile, aequabile crassitudinis, ac altam plating facultatem.
6. Solutio platonis stabilis, facilis ad operandum, facilis ad conservandum.
2. Solutio compositionis et conditionis operativae

3.Plating solutionem praeparationis
1. piscinam mundare, duae tertias partes aquae voluminis addere, et calorem 45 ℃.
2. Chromicum anhydride (250g/L) adde et bene excita.
3. Additio acidi chemici puri sulphurici (II. 5 G / L note contentum chromii sulphatis anhydridis deductum) et misce.
4. Adde 20 ml/L chromium durum additivi CR-2, adde aquam ad volumen requisitum, et aequaliter excita.
5. Pone anode plumbi plumbei continens 7-10 % Sn, cathode falso utere cum area quinquies anodae, eamque in D k = 15A/d ㎡ pro 4 horis producere ad chromium trivalens debitam quantitatem.
6. Laminatio solutionis ad 55 calefaciendum et electroplatandum committitur.
4. Proxime 10ml CR-2 chromium durum additivi additur pro omni 1000 AH electricitatis, vel 5-7 literae CR-2 chromii duri additivi pro singulis 100 kg chromici anhydridis adiectis.
2.H 2 SO. 4 normales concentratio 2. . 5 G / L. Solet acidum sulphuricum non consumptum, solo amisso.
3. Commendatur nostrum productum CR-53 vel CR-53A addere chromium caligini inhibitoris ut chromium caligo minuatur et evadat et labefactetur aer pollutionis et detrimentum materiae chemicae rudis.
1. Approximately 10ml of CR-2 hard chromium additive is added for every 1000 AH of electricity , or 5-7 liters of CR-2 hard chromium additive for every 100 kg of chromic anhydride added .
2.H 2 SO . 4 normal concentration of 2. . 5 G / L. Usually sulfuric acid not consumed, with the loss only.
3. It is recommended to add our product CR-53 or CR-53A chromium mist inhibitor to reduce chromium mist escape and avoid air pollution and loss of chemical raw materials.
