Abstract
The invention relates to an improved hot galvanizing method of an iron handicraft or furniture. The method comprises the following steps: (1) uncoiling and degreasing a workpiece; (2) removing dust; (3) washing; (4) assisting plating; (5) baking; (6) galvanizing by dipping; (7) settling; (8) passivating; (9) cooling. In the method, a degreasant is changed into acidity and is composed of a sulfuric acid solution, OP-10 and di-o-tolyl-thiourea. Thus, a washing procedure can be saved; a water resource and the degreasant can be saved; the workpiece does not generate an over-cleaning phenomenon; a pickling solution is composed of a hydrochloric acid solution, phosphoric acid, alkylphenol ethoxylates, lauryl sodium sulfate and ethylenediamine tetraacetic acid, so that the pickling speed is improved, formation of acid mist and use of a complexing agent can be restricted, reduction of cadmia in galvanizing zinc is facilitated, the malleability of a zinc coating on the surface of the work-piece is improved, proper temperature and event are adopted in the subsequent galvanizing by dipping, and the thickness and the stability of the zinc coating at the surface of the workpiece are ensured. Thus, the improved hot galvanizing method is a method which is simple and convenient for operation and good in galvanized effect.
Description
Technical field
The invention belongs to the Hot Galvanizing Technology field of metal products, the improvement hot galvanizing method of especially a kind of irony artwork or furniture.
Background technology
Zinc is soluble in acid, also can be dissolved in alkali, is a kind of amphoteric metal, and it changes hardly in dry air, and in malaria, its surface can generate fine and close zinc subcarbonate film, so zinc is often used as coating to protect other metal.After common steel substrate top layer is zinc-plated, fine and close zinc layer has been protected steel substrate, and when breakage appears in zinc layer, zinc is as anode, and steel substrate, as negative electrode, so first zinc corrode, has been protected steel substrate.
The normal galvanized method using was electro galvanizing and Aplataer process in the past, and electro galvanizing is utilized electrolysis, on the surface of workpiece, form evenly, densification, in conjunction with good technology or alloy deposition layer, but the thinner thickness of electro-galvanizing.Aplataer process is that the steel part after rust cleaning is immersed in the zinc liquid melting, and makes workpiece surface adhere to zinc layer.Wherein Aplataer process comprise oil removing degreasing, washing, rust cleaning, wash, help plating, the step of oven dry, galvanizing, cooling, passivation, washing, oil removing degreasing in said process more often adopts sodium hydroxide, sodium carbonate, water glass mixed aqueous solution under more than 90 degrees Celsius hot conditionss, to carry out the degreasing of workpiece, and in working process, large, the workpiece surface of smell there will be and leaks iron phenomenon or coarse injustice; Single sulfuric acid or hydrochloric acid are used in rust cleaning, easily make workpiece surface occur excessive erosion or hydrogen evolution phenomenon; In galvanizing process, the amount of cadmia and zinc gray is larger, directly causes increasing of pot galvanize cost.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, scientific formulation, a kind of compound nutritional feed weaning in advance for piglet that piglet survival ratio is high are provided.
The technical scheme that the present invention takes is:
