Problems solved by technology

[0002] As a large system engineering in current construction engineering, fire protection engineering has always been concerned by architects. Some fire protection engineering has problems in drawing design. Intelligent engineering does not include engineering construction of the building part, such as the width of escape stairs. , the distance between buildings, fire lanes, etc. In the fire protection engineering, it is particularly important to choose good quality windows for the construction of fire pump rooms. How to prepare good windows and improve the preparation of existing metal windows is a problem for technicians to solve

Embodiment

[0011] Embodiment The manufacturing process of the metal window of the fire-fighting pump room includes the following steps, pretreatment, making the surface of the workpiece clean, uniform, and grease-free through degreasing, rust removal, and phosphating processes; in the first step, phosphating is to use manganese phosphate, Metal workpieces are treated with zinc and cadmium orthophosphate solutions to form an insoluble phosphate protective layer on the surface of the workpieces. The formed phosphating film has a dense structure with fine pores, which increases the surface area of ​​the workpiece and greatly improves the organic Adhesion of the coating to the workpiece. Drying, quality inspection before hanging, visual inspection of unpainted workpieces before going online; grinding, removing granular impurities on the surface of the workpiece with water sandpaper to increase roughness; hanging, hooking the workpiece on the hanger, the hanger is conductive and Move with the...

Abstract

The invention discloses a manufacturing process of a metal window of a fire-pump room. The manufacturing process is characterized by comprising the following steps: pretreatment: performing degreasing, dedusting and phosphorization working procedures to enable the surface of a workpiece to be clean, uniform and grease-free; drying and production inspection before racking: checking the appearance of the workpiece which is not coated; grinding: removing granular impurities from the surface of the workpiece with waterproof abrasive paper to enhance the roughness; racking: hooking the workpiece on a hook, electrifying the hook and driving the hook to move along the assembly line; dust collection after the workpiece is racked; coating and drying: automatically coating for treatment by adopting manual coating or Disk automatic coating; coating repairing: checking a defected part or a part which cannot be coated, and repairing the coating; and baking in a preheating furnace: baking a product in a main furnace, taking down the product from the hook, and packing the product.
