add zinc chloride and ammonium chloride

Stainless steel, Molybdenum tube austenitic stainless steel technology
   Flux kind of stainless steel, stainless steel can not be performed to solve the conventional problem of soldering, using phosphoric acid, zinc chloride, ammonium chloride, water, composition, use of phosphoric acid to the oxidizing agent, and because of its high temperature viscosity of water left after evaporation viscous substance adhering to the stainless steel surface to prevent secondary oxidation properties, add zinc chloride and ammonium chloride, in the welding of stainless steel to form an alloy of tin and solder layer so as to achieve the purpose. Not only can be used for soldering copper, iron and other materials can also be used for stainless steel and chrome-plated, nickel-plated solder surface. Discloses a stainless steel mounting type ophthalmic operating table, it is made mattress, bed legs can lift the head and the head fixing bracket plates, the bed with the lower leg fastening buttons, the adjusting bolt, the adjusting nut and the sleeve pin 13, bed legs by tightening the adjusting knob lift; mattress head bracket located at one end; head bracket with fixing plate can lift the head, the lower part of the elevator shaft, mounted on the lifting comprising lifting shaft, lifting sleeve wall has through holes, fastening buttons inserted into the through hole to adjust the movements of the head fixing plate. This product is a simple structure, flexible operation, good stability, safety and reliability. Provided at a low cost and practically sufficient bonding strength of the bonded tungsten carbide cemented carbide as a main component member and the stainless steel component excellent technical practicality. The present invention is mainly composed of tungsten carbide hard alloy member 1 and the method of joining steel member 2 is characterized in that the hard alloy member 1 and the steel member 2 are connected to the electrodes 3, in which cemented carbide member 1 and the steel member 2 are pressed against each state, the pulse current flows from the electrodes 3, tungsten carbide and stainless steel member 2 member 1, and then bonded by welding of the both. Kinds of stainless steel chemical polishing method, based on sulfuric acid as a carrier, sodium chloride, sodium (or potassium fluoride), sodium nitrate instead of the corresponding acid, the first solution of the salts dissolved in an aqueous solution of starch, will want polished stainless steel immersed in this solution, adhered to the surface layer of the salts dissolved in the starch layer and then polished of this material was immersed in sulfuric acid solution in a suitable temperature range for chemical polishing, usually when the solution is green, the polishing process is completed. The present invention does not produce mist, improving the work environment, reducing the production cost. The invention has practical and economic value for steel device erosion.
