Embodiment Construction
[0018] The following clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0019] The invention provides a process for solving the abnormal noise of the car door lock, which includes the following steps:
[0020] (1) Degreasing for the first time: first degrease the car door lock with degreasing liquid, the agent used is a white granular degreasing powder containing heavy metal surfactant and sodium hydroxide, the concentration is 80-120g / L, The degreasing temperature is 60-70°C, and the degreasing time is 15-30 minutes, which can effectively remove most of the oil stains on the surface of the parts.

The invention provides a car door lock catch abnormal sound solving process. The car door lock catch abnormal sound solving process comprises the following steps: (1) firstly performing first-time oilremoval on a car door lock catch; (2) performing shot-blasting on the car door lock catch through shot-blasting equipment; (3) performing oil-removal again on the car door lock catch through oil-removal liquid; (4) pickling, wherein hydrochloric acid is used to perform pickling on the car door lock catch; (5) performing electrolytic oil-removal: using an electrolytic oil-removal reagent to perform electrolytic oil-removal on the car door lock catch; (6) adopting a plating solution to perform electroplating, wherein an electroplating thickness is 8-35 mm; (7) using a passivating agent to passivate the car door lock catch; (8) using a nano type sealing agent to seal; and (9) using wax water to coat wax to the surface of the car door lock catch. The car door lock catch abnormal sound solvingprocess solves the abnormal sound problem generated when a car door is closed of the lock catch, takes a lubricant as a buffer agent of the car door lock catch, and enables the coating surface of thecar door lock catch to be smoother and more uniform, and therefore, friction force of the surface of the car door lock catch is reduced, and abnormal sound when the car door lock catch is used is obviously relieved.
Description
technical field [0001] The invention relates to the field of surface treatment of lock parts for automobiles, in particular to a process for solving abnormal noise of car door locks. Background technique [0002] The car door is to provide the passage for the driver and passengers to enter and exit the vehicle, and to isolate the interference from the outside of the vehicle, to reduce side impact to a certain extent, and to protect the occupants. The beauty of the car is also related to the shape of the door. When the car door is closed, it is through the dead bolt and buckle on the door lock body. In practical application, when the car door is closed, the car door lock often makes abnormal noise, which reduces user satisfaction. Contents of the invention [0003] The purpose of the present invention is to provide a process for solving the abnormal sound of the door lock. [0004] The technical solution of the present invention: the process for solving the abnormal soun...
