Abstract
The invention discloses a method for prolonging service life of a zinc liquid cooling water pipe. The method includes the following steps: adding aluminum dihydrogen phosphate of 80-120g into cobalt oxide of 10-15g, uniformly coating on the outer surface of the cooling water pipe after fully mixing, drying at 150 DEG C; retaking silicone resin of 80-120g, red iron oxide of 20-40g, and talcum powder of 20-40g, uniformly coating on the outer surface of the cooling water pipe after fully mixing, drying at 150 DEG C, thereby obtaining the zinc liquid cooling water pipe with a corrosion resisting coating. Because of the corrosion resisting coating on the surface of the zinc liquid cooling water pipe, the direct corrosion of the zinc liquid to the seamless steel tube is cut off, the service life of the zinc liquid cooling pipe is prolonged, thereby avoiding the frequent changes, lowering the cost of production, and improving the production efficiency.
Description
Technical field
What the present invention relates to is the zinc liquid cooling tube that uses in a kind of zinc metallurgy industry, specifically a kind of method that improves Zn liquor cooled water tube life-span.
Background technology
Current, in zinc metallurgy industry, be extensive use of the cooling that the cooling tube that is formed by the weldless steel tube clod wash is realized zinc liquid.Because the surface tension of zinc liquid is little, perviousness is strong, and corrodibility is strong, can generate iron-zinc alloy with the ferro element in the cooling tube, can dissolve element such as carbon, silicon in the cooling tube.Zinc liquid to the deep-etching of cooling tube, makes cooling tube just be washed away leakage in a short period of time in flow process, and the cooling-water flowing in the pipe is in zinc liquid, and must in time change could ordinary production.Because zinc liquid cooling tube is short work-ing life, the consumption of cooling tube is quite big in the zinc metallurgy, and frequent replacing has improved production cost, has reduced production efficiency.
Summary of the invention
In order to solve the deficiencies in the prior art, the purpose of this invention is to provide a kind of Zn liquor cooled water tube method in work-ing life that improves.
The object of the present invention is achieved like this, evenly is coated onto on the outside surface of water-cooled tube behind the cobalt oxide thorough mixing with 80～120 aluminium dihydrogen phosphates adding 10～15 grams that restrain, and dries under 150 ℃ of temperature; Get the silicone resin of 80～120 grams, the red iron oxide of 20～40 grams, the talcum powder of 20～40 grams again, to evenly be coated onto again behind three's thorough mixing on the outside surface of water-cooled tube, under 150 ℃ of temperature, dry, both can obtain Zn liquor cooled water tube with corrosion-resistant coating.
The beneficial effect that the present invention is compared with prior art had is: because the surface of Zn liquor cooled water tube scribbles corrosion-resistant coating, cut off of the direct corrosion of zinc liquid, improved the work-ing life of zinc liquid cooling tube, avoided frequent replacing weldless steel tube, reduce production cost, improved production efficiency.
Embodiment
A kind of Zn liquor cooled water tube method in work-ing life that improves of the present invention, it realizes that the concrete steps of this method are evenly to be coated onto on the outside surface of water-cooled tube after earlier 80～120 aluminium dihydrogen phosphates that restrain being added 10～15 cobalt oxide thorough mixing that restrain, and dry under 150 ℃ of temperature; Get the silicone resin of 80～120 grams, the red iron oxide of 20～40 grams, the talcum powder of 20～40 grams again, to evenly be coated onto again behind three's thorough mixing on the outside surface of water-cooled tube, under 150 ℃ of temperature, dry, both can obtain Zn liquor cooled water tube with corrosion-resistant coating.Because the surface of zinc liquid cooling tube scribbles corrosion-resistant coating, has cut off the direct corrosion of zinc liquid to weldless steel tube, avoids frequent replacing the work-ing life of having improved Zn liquor cooled water tube, has reduced production cost, has improved production efficiency.Described aluminium dihydrogen phosphate is a colorless and odorless utmost point heavy-gravity liquid; Soluble in water, to solidify at normal temperatures, bonding force is strong, high temperature resistant, anti-vibration, antistripping, high temperature resistant airflow scouring, and have good red line receptivity and insulativity, be a kind of high temperature resistant, corrosion resistant material.Described cobalt oxide is a kind of grey black toner end, is dissolved in acid, with steel very strong tack is arranged.Aluminium dihydrogen phosphate be coated onto on the steel pipe and can firmly adsorb after cobalt oxide mixes with steel pipe.Described silicone resin, formal name used at school are polyorganosiloxane resin; Have good anti-corona, arc resistance,, good brightness and wear resistance are arranged attached to the metallic surface.Described red iron oxide is acidproof, alkaline-resisting, heat-resisting, and chemical stability is good, and good tinting strength and opacifying power are arranged.Good physics, chemical propertys such as described talcum powder has that oilness, resistivity against fire, resistance to acid, insulativity, fusing point height, chemical torpescence, opacifying power are good, softness, good luster, adsorptive power are strong.Silicone resin, red iron oxide, talcum powder three have characteristics such as adsorptive power is strong, wear-resisting, corrosion-resistant, chemical stability is good after mixing.
