At present, the processes commonly used in the industry mainly include the following steps: steel purchase inspection, pretreatment, degreasing, water washing, pickling, FLUX, galvanizing, water cooling, entering the finishing area on the trolley, quality inspection and finishing, Packaging, putting into the warehouse for bribery and delivery. Because the steel plate is a plate-shaped maggot, both sides of the entire steel plate will be mineralized when the mirror zinc step is immersed in the liquid. However, in some cases, it is not suitable to make money face to face, and it is difficult to pour steel sheets with single zinc. In the prior art, in order to manufacture a single-sided galvanized steel sheet, the process generally used is to ^ a steel sheet coated with zinc on both sides. The side of the steel sheet that is not to be plated is immersed in an acid solution again. The acid solution is used to wash away the zinc that has been produced in the company, so that a single steel sheet can be obtained. However, 'the old process 4' has many disadvantages. Immerse both sides of the steel plate in acid solution to wash off the galvanization on one side. This will increase the number of steps in the process, especially on the production line. If only the -S tank is set, the acid solution tank must be executed on the steel plate. The treatment of acid solution before mirror zinc must be carried out to read the two sides of the steel plate that has been zinced on the double side, which will hinder the speed of the production line and increase the amount of acid solution and zinc solution. ^ An acid tank is installed behind the zinc tank, which is used to dissolve and remove the zinc-plated steel plate on both sides of the zinc plate after the galvanizing step. Although it will not hinder the manufacturing process, the y liquid Slots, strict housing areas are bound to increase, and more acid solution is also needed, all of which increase "" costs. Therefore, it is true that a method of manufacturing single-sided galvanized steel sheet is required, which can shorten the process time, increase the output, and reduce the wave of the processing liquid. [Summary of the Invention] Jia further increases the cost. 200536958 In view of the above problems, the present inventor has designed the present invention based on the experience of the inventor over the years in the galvanizing process. According to the present invention, a method for manufacturing a single-sided galvanized steel sheet is proposed, which includes the following steps: steel product inspection, pre-treatment, coating with acid-resistant substances, degreasing, water washing, pickling, FLUX, galvanizing, and water cooling Among them, in the pre-treatment step, before the degreasing step is performed, a layer of acid-resistant material is coated on a steel plate that is not to be galvanized, and then the steel plate coated with acid-resistant material is sequentially degreased, washed, Pickling, flux (FLUX), galvanizing, etc. Since the acid-resistant substance is an unsaturated polyester resin, the acid-resistant substance will not be removed after degreasing, water washing, and acid washing. The isolation of the acid-resistant material makes it impossible for the zinc liquid to adhere to the surface steel plate coated with the acid-resistant material when the galvanizing treatment is performed, so that a single-side galvanized steel plate is formed. With the above method, when a steel sheet with only one surface is to be manufactured, as long as an acid-resistant substance is coated on the surface steel sheet that is not to be spared, it can be manufactured according to the process originally used to manufacture double-sided galvanized steel sheets. Does not hinder the original production line, and does not need to be immersed in the acid solution tank again in order to dissolve away the excess zinc plating, so it can save the use of acid solution and distillate, simplify the process, increase the output and reduce the cost. efficacy. [Embodiment] Hereinafter, a method for manufacturing a single-sided galvanized steel sheet according to the present invention will be described in detail with reference to the accompanying drawings. φ First, considering the process shown in the first figure, the method of manufacturing a single-sided ore zinc steel sheet according to the present invention 'includes the following steps: steel product inspection, pre-treatment S20, coating with acid-resistant substance S25, degreasing S30, and washing S40 , Pickling S50, flux (FLUX) S60, galvanized S70, water-cooled S80, 'In the pre-treatment step S20, before the steel plate has not been degreased, apply a layer of acid resistance on the steel plate that is not to be galvanized. Material, and then the steel plate coated with acid-resistant material, the entire steel plate is sequentially degreased S30, water washing S40, acid washing S50, cosolvent (FLUX) S60, galvanized S70 and other treatments. Since the acid-resistant substance is an unsaturated polyester resin, the acid-resistant substance will not be removed after the steps of degreasing S30, water washing S40, and acid washing S50. The isolation of the acid-resistant material prevents the zinc solution from adhering to the surface steel plate coated with the acid-resistant material when performing galvanizing S70 treatment. Therefore, it can only adhere to the other steel plate not coated with the acid-resistant material 6 200536958. A single-side plated steel sheet is formed. In contrast, the process with reference to the second figure shows the method for manufacturing single-sided ore steel sheet in the prior art. The same steps as the present invention are marked with the same parameters. The method in the prior art includes the following steps: steel purchase Inspection S10, pretreatment S20, degreasing magic 0, water washing S40, pickling S50, flux (FLUX) S60, galvanizing S70, pickling S50, water cooling S80. In order to manufacture the single-sided plated steel sheet, when the steel sheet has undergone steps such as steel incoming inspection sl10, pre-treatment S20, degreasing S30, water-washing S40, pickling S50, flux (FLUX) S60, galvanized S70, etc. After the steel sheet that has been freed, the side of the steel sheet that is not to be galvanized is placed in a scum bath, and a pickling S50 is applied, and the plated metal is washed away with an acid solution to become a single-sided plated steel sheet. Obviously, according to the present invention, it is only necessary to separately distinguish the steel sheet to be made of single-sided galvanizing in the pre-treatment S20 step, and apply the acid-resistant substance S25, and then degreasing with the double-sided galvanized steel sheet S30, The steps of water washing S40, pickling S50, flux (FLUX) S60, galvanizing S70, etc. will not hinder the speed of the production line, and there is no need to perform additional pickling S50. The zinc in the middle will remove the acid and zinc. waste. Therefore, compared with the prior art, the method for making a single-sided riding steel plate can indeed shorten the processing time of the green technology, increase the yield, and reduce the waste of processing fluid, thereby saving costs. Although the present invention has been described based on the above embodiments, it should be understood that for those skilled in the art, after reading the disclosure of the present invention, other modifications and equivalent substitutions can be conceived. Therefore, the scope of the present invention should not be limited by the above specific embodiments, but should be defined by the following patent application scope.
