Abstract
The present invention relates to a technology for conducting treatment and electroforming deposition on a non-metal mould by an electrochemistry principle, which belongs to an electroforming technology. In the technology of the present invention, silver nitrate prepared from silver nitrate, water and absolute alcohol is used as a coating layer, hydrogen sulfide gas is sprayed after the silver nitrate is naturally dried, a silver oxide conductive body can be formed on the surface of a model, and then the model enters a groove for electrolyzing. The technology of the present invention has the advantages of low production cost, simple and convenient operation technology, high manufactured work original work faithful degree, strong artistic texture, good corrosion prevention, long storage time, etc. and solves the problem of the large silver consumption of an electroforming product for a long term, and the technology of the present invention has obvious economic benefit.
Description
The present invention system utilizes electrochemical principle, carries out the sedimentary technology of electroforming on nonmetal mould.Be mainly used in and make the big-and-middle-sized scuoptor elaboration of indoor and outdoor, duplicate all kinds of imitations of an ancient bronze, and art of architecture bronze, brass or copper ware decoration etc.Belong to nonmetal electroforming process.
Nonmetal electroforming, what at first will solve is the method problem of electrical conductor.The conductive processing of the non-metallic body that has adopted at present mainly contains two kinds of methods.A kind of is heavy silver-colored method, and it needs finish with four procedures: on the non-conductor mould, brush one deck shellac earlier waits and sprays one deck nitro again after doing and spray paint (1); (2), clean with sodium hydroxide solution, to remove wax-pattern surface grease at the coating surface degrease; (3) sensitization is handled, and brushes the mixed solution of one deck tin protochloride and hydrochloric acid, through the washing seasoning; (4) heavy silver is soluble in water with 25% Silver Nitrate, and is heavy clear with 5% ammoniacal liquor, adds 20% glucose and make catalytic reduction, adds and stir, and then mould is submerged in the solution, makes die surface form one deck silver layer, conducts electricity with this.This method complex process, the Silver Nitrate consumption is big, and therefore the production cost height can only be fit to make small-sized works and trial-production experiment.Another kind is taken a lot of work too big with Graphite Powder 99 or metal-powder swabbing process (in October, 77, National Defense Industry Press published＜plating handbook〉first volume introduction) when operating though this method cost is low.Particularly the dark recess part of mould is difficult to clip, thereby, just can not deposit metal.Its maximum shortcoming is: (1) conduction speed is extremely slow, influences production schedule.(2) to the moulding complexity, the works that surperficial concave curvature is big can not adopt, so this conductive method just can't be finished large-scale artistic work.
The objective of the invention is to provide a kind of with short production cycle, cost is low, and conductivity is strong, and the simple non-metallic body conductive processing method of operating procedure is to be fit to make the electroforming art bronze statue (device) and the electroforming moulding articles for use of all size, elaborate.
Technical scheme of the present invention is to consider like this: on the wax-pattern after the modification, directly brush the silver nitrate solution of one deck by Silver Nitrate, water and dehydrated alcohol preparation with hairbrush, after waiting its seasoning, spray is with hydrogen sulfide, make model surface form the oxidation silver layer of one deck iron cyan, go into the groove electroforming then.
Below will be described in detail embodiments of the invention.
On original work, turn over system gypsum piecemeal mould, water with gypsum piecemeal mould again and make wax pattern.Before watering wax, plaster mould will soak with clear water, with the solar heat protection wax bite.The composition of wax fat is: 8 parts in paraffin, stearic 2 parts, the wax temperature should be controlled at about 800 degree when casting, and carries out conductive processing after shaping investment pattern is modified.Be mixed with silver nitrate solution for 30 milliliters with Silver Nitrate 1 gram, 10 milliliters in water, dehydrated alcohol, this solution is coated in the wax-pattern surface equably, dark recess can wash away with solution, and the wax-pattern after the coating is placed in the natural temperature dry.20 milliliters of hydrochloric acid and 20 gram iron sulphide are obtained hydrogen sulfide after putting into the flask internal heating, and this gas is sprayed on the oxidation silver layer that generates one deck iron cyan behind the wax-pattern surface with the Silver Nitrate chemical reaction.So far, wax-pattern can be gone into the groove electroforming.After wax-pattern enters in the copper-bath groove,, after surface electrical cast layer thickness reaches 1.5～2 millimeters the grooving flushing through 72～90 hours.Because the brass work thickness after the electroforming generally below 3 millimeters, needs to handle through quick fire, quick fiery temperature is controlled between 300～400 degree.The surperficial stain of electroform product adopts chemical rightenning to handle, and available nitric acid, phosphoric acid, glacial acetic acid liquid mixture prepared are brushed in the surface, and flushing with clean water is clean after 2～3 minutes.At this moment after modifying a little, goods can obtain Electrotyping of bronze statue.
Explained hereafter cost of the present invention is low, and operating procedure is simple, and the works that make can verily reproduce original work, and artistic texture is strong, and antiseptic property is good, preserves a year limit for length, is a kind of having an economic benefit very much and the non-metallic body conductive processing technology of practical value.
