Embodiment Construction
[0026] In order to make the purpose and technical solution of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention.
[0027] Such as Figure 1-3 Shown, a kind of slide block surface is coated with the method for teflon, on the surface of wherein one side of described slide block 1, offer groove 2, the method for slide block surface coat teflon comprises the steps:
[0028] Step 1: roughen the surface of the slider 1 to increase the surface roughness and increase the surface adhesion of the slider, so that the Teflon coating can be better combined with the surface of the slider. Sandblasting is used to increase the surface roughness of the slider.
[0029] Step 2: Clean the slider 1 with a weak acidic solution to remove surface oil, rust, etc., so as to prevent the dirt from affecting the bonding effect between the Teflon and the slider. If ther...

Abstract
The invention discloses a method for enabling the surface of a sliding block to be coated with teflon. The method comprises the steps that firstly, the surface of the sliding block is subject to coarsening treatment, and the surface roughness is increased; secondly, a weakly acidic solution is adopted to clean the sliding block, and the surface oil contamination and the corrosion are removed; thirdly, the cleaning solution remaining on the surface of the sliding block is dried, and the sliding block continues to be heated to 100 DEG C; fourthly, spraying is carried out; fifthly, drying is carried out, wherein the sprayed sliding block is put into an oven at the temperature of 180 DEG C, and subject to heat preservation treatment for 8 hours, and curing of a teflon coating is carried out; sixthly, the sliding block treated in the fifth step is cooled to the room temperature. Through the roughness treatment, cleaning, preheating, drying and other steps of the sliding block, the combination force between the teflon coating and the sliding block surface is improved, and a coating is prevented from peeling off; the surface of the sliding block is sprayed with a teflon solution, the coating is formed, and the corrosion resistance of the sliding block is improved; meanwhile, the teflon solution is adopted to carry out spraying, spraying of the teflon solution is the physical process, harmful substances polluting the environment are not generated, and the method is environment-friendly.
Description
technical field [0001] The invention belongs to the technical field of sliding block surface coating, and in particular relates to a method for coating the surface of a sliding block with Teflon. Background technique [0002] Linear slide rails and sliders are important mechanical components, and are widely used in precision machinery, automation industry, semiconductor industry, medical equipment, aerospace industry, etc. The main function of linear slide rails is to use the rolling of balls or rollers to reduce the The frictional resistance when the mechanism moves makes the movement of the mechanism more labor-saving and energy-saving. At the same time, due to the reduction of friction and the wear of the contact surface, the accuracy and life of the mechanism are greatly improved, and the movement of the mechanism The speed limit has also been greatly improved, so the linear slide rail can be regarded as a very important mechanical transmission component in recent years....
