Description
Technical field
The present invention relates to the quick production technique of a kind of basic nickel carbonate or cobaltous dihydroxycarbonate.
Background technology
Basic nickel carbonate [NiCO
32Ni (OH)
24H
2O], cobaltous dihydroxycarbonate [2CoCO
33Ni (OH)
2H
2O] product is widely used in industries such as accuracy electroplate, electroplating printed circuit board, general-purpose alloy plating, nickel cobalt (alloy) electroforming, ceramic industry, commercial catalysts, and it is widely used, and demand is big.At present the enterprise of this product of domestic production is more, but quality product compares with the import like product bigger gap is arranged, and major cause is that production technique is relatively backward, exists many problems should improve and perfect.
The production technique of these two kinds of products has manual operations and semi-mechanization to produce two kinds at present.With alkali formula carbon nickel method for making is example, pass through complicated procedures of forming such as reaction, washing, filtering separation, drying, pulverizing, screening, just makes basic nickel carbonate finished product (cobaltous dihydroxycarbonate and basic nickel carbonate method for making are basic identical) at last.All more or less there is certain defective in the comprehensive production technique of each enterprise at present.Such as, wash this operation, soon 3-4 days, generally to want just can finish about a week, filtering separation also needs 1-2 days.Add drying, the operation of pulverizing, sieve, not only process cycle is long, and processing parameter be difficult for to grasp, and as drying process, because overlong time, temperature distributing disproportionation are even, causes local temperature too high, causes the product dehydration easily, influences quality product.Above-mentioned in addition explained hereafter operation labour intensity is big, and dust pollution is serious, is unfavorable for health of operators, the production cost height, and industrial scale also is subjected to the influence of production technique.
Summary of the invention
The objective of the invention is to: overcome the defective of existing basic nickel carbonate or cobaltous dihydroxycarbonate production technique, provide that a kind of technology is simple, with short production cycle, labour intensity is little and the basic nickel carbonate of constant product quality or cobaltous dihydroxycarbonate production technique.
Production technique of the present invention may further comprise the steps:
A), dissolving: starting material nickelous chloride or cobalt chloride, soda ash are put into reactor respectively and dissolved, be liquid after the dissolving;
B), synthetic: alkaline solution and nickelous chloride or cobalt chloride solution are added another reactor carry out building-up reactions, add alkaline solution earlier, after add nickelous chloride or cobalt chloride solution, and stir, control sprays and stirring velocity, the pH value of solution value transfers to 〉=7.5～9.5;
C), filter washing: the solution that building-up reactions is good is put in the sheet frame and is washed, and in the washing process, should note the water yield, about dividing, about and the centre washing of changing sides, guarantee the homogeneity of washing, the washing time is 2.5～4.5 hours, constituent contents such as sampling analysis Na, Cl after washing is finished with control washing quality, are controlled at≤the 0.01g/ liter until Na, Cl content, after washing is finished, increase to 0.8～1.6MPa again, extrude moisture content, squeezing after 30 minutes is that dismountable sheet frame takes out filter cake.
D, drying: filter cake is directly entered drying oven carry out drying, control input speed and drying temperature well, temperature controlling will be done wet degree according to filter cake, and general temperature is controlled at about 60～80 ℃.
Nickelous chloride or cobalt chloride dissolving ratio is NiCl by mass ratio in the dissolution process of technology of the present invention
2: H
2O=1: 4～8, CoCl
2: H
2O=1: 4～8, yellow soda ash dissolving ratio by mass ratio is: Na
2CO
3: H
2O=1: 4～8.
Alkaline solution and nickelous chloride or cobalt chloride solution take the spray mode to add in the building-up process of technology of the present invention.
The synthesising reacting time of technology of the present invention is 2～4 hours.
The present invention has realized the fast fast preparation method production of cover basic nickel carbonate, cobalt product.Not only production technique is simple, and is with short production cycle, and labour intensity is little, and industrial scale can enlarge arbitrarily, and operation is simple, and cost is low, steady quality, efficient height.This technology has the advantages that to produce fast, product high-quality, efficient height, washes disposablely just can go out product, compare with traditional method, and power saving, water-saving, the saving of labor saves time, and is laborsaving.Convenient, can save production cost big spoke degree.Product does not need through crushing screening, and product particle is evenly fine again, helps using.Both reduce the pollution of dust in the production, improved the protection of work again, met the requirement of modern production fully.
