Description

Surface treatment method for elevator guide rail workpiece
Technical Field
The invention belongs to the technical field of elevator guide rails, and particularly relates to a surface treatment method for an elevator guide rail workpiece.
Background
At present, vertically-lifting elevators and escalators are the mainstream varieties in the elevator industry, wherein the vertically-lifting elevators account for about 80% of the total amount of the existing elevators, so that the vertically-lifting elevators become an important product which is closely related to the life of people, and the quality condition of the vertically-lifting elevators is also closely related to the lives and properties of people. In which the elevator guide rails, as an important part of the quality control of a vertical lift elevator, will directly affect the safety and comfort of the elevator. The elevator guide rails are two or more rows of vertical or inclined rigid rails arranged in an elevator shaft or between floors, so that the elevator car and the counterweight can move up and down along the elevator guide rails, and the quality of the elevator guide rails is directly related to the safety and the running quality of the elevator. After the elevator guide rail workpiece is manufactured, a layer of anti-rust oil needs to be coated on the surface of the elevator guide rail workpiece, and a protective film needs to be attached to the surface of the elevator guide rail workpiece, so that the elevator guide rail is prevented from being rusted and scratched in the transportation and use processes.
At present, the procedure of coating the anti-rust oil is to place an elevator guide rail workpiece on a guide rail, and drive a coating roller to move to coat the surface of the elevator guide rail workpiece under the motion of the guide rail, but due to the different kinematic viscosity of the anti-rust oil, the phenomena of uneven coating of the anti-rust oil, flow casting of the anti-rust oil and the like can be caused, so that the elevator guide rail workpiece can be damaged, a protective film can be easily peeled off from the elevator guide rail workpiece, the elevator guide rail cannot be protected by the film and the anti-rust oil in the transportation process, and the phenomena of scratching and rusting are caused.
In view of the defects in the existing anti-rust oil, the inventor develops a surface treatment method for an elevator guide rail workpiece based on years of design and manufacture of the products, abundant practical experience and professional knowledge, proficient and full application of a chemical mechanism, and continuous research and innovation in practice.
Disclosure of Invention
The invention aims to provide a surface treatment method of an elevator guide rail workpiece, which solves the technical problems of uneven coating, tape casting and the like of an antirust oil film layer.
The invention is also suitable for the commercially purchased antirust oil before use according to the requirements of workpieces or preparation procedures, and solves the problems of roller sticking, tape casting, oil spilling and the like of the antirust oil generated when the kinematic viscosity of the antirust oil is inconsistent with the process requirements.
The technical purpose of the invention is realized by the following technical scheme:
the invention provides a surface treatment method of an elevator guide rail workpiece, which comprises the steps of coating anti-rust oil on the surface of the elevator guide rail workpiece and then pasting a film; wherein the dosage of the diluent in the rust preventive oil is determined according to the kinematic viscosity of the rust preventive oil, and the calculation formula of the kinematic viscosity of the rust preventive oil is as follows:
Figure DEST_PATH_IMAGE002
wherein
Figure DEST_PATH_IMAGE004
Is the kinematic viscosity of the rust preventive oil, and the unit is 10-6m2S is the surface roughness of the elevator guide rail workpiece, and the unit is mum; h is the thickness of the rust preventive oil film layer in μm, V is the coating speed of the rust preventive oil in m/s, and a and b are coefficients, not calculated in units. The kinematic viscosity of the rust preventive oil determines the thickness of the coating film layer under the same coating speed and the same surface roughness; if the kinematic viscosity of the rust preventive oil is too high, the coating is not uniform, a compact film layer cannot be formed, the bonding force between the rust preventive oil and a subsequent protective film is reduced, the protective film is easy to peel off, and if the kinematic viscosity of the rust preventive oil is too low, the rust preventive oil can be cast, and a uniform and compact film layer cannot be formed; therefore, the antirust oil with different kinematic viscosities is suitable for different coating speeds and workpiece surface roughness; the thicknesses of the film layers formed by the anti-rust oil with different kinematic viscosities are different, and the anti-rust oil film layers with different thicknesses are required to be coated on the elevator guide rail workpieces with different surface roughnesses. The reason why the kinematic viscosity is adopted but not adopted in the present invention is that the application of the rust preventive oil is a dynamic process, and therefore the kinematic viscosity is more accurate.
The kinematic viscosity referred to in the present invention is the kinematic viscosity of a liquid at 40 ℃ and is the kinematic viscosity of a fluid in mm when the fluid flows under gravity2The resistance in the/s meter was measured using ASTM D445-06.
The surface roughness referred to in the invention refers to the small pitch and the unevenness of the tiny peaks and valleys of the machined surface, and is measured according to GB/T131-.
The thermal expansion coefficient of the elevator guide rail workpiece related to the invention is measured according to the method provided by GBT4339-2008, and only the numerical value of the thermal expansion coefficient of the elevator guide rail workpiece at 20 ℃ is taken in the invention, and the unit is not calculated.
Further, a is the value of the thermal expansion coefficient of the elevator guide rail workpiece at 20 ℃. The elevator guide rail workpieces made of different materials have different thermal expansion coefficients, and the thermal expansion coefficient of the surface of the workpiece has the same influence on the spreading of the anti-rust oil and the surface roughness of the workpiece, so that the surface roughness is modified by adopting the thermal expansion coefficient, and the calculation accuracy of the motion viscosity of the anti-rust oil can be improved.
Further, in the above-mentioned case,

wherein T is1Is the temperature, T, of the elevator guide rail2The temperature of the rust preventive oil. The temperature difference between the elevator guide rail and the anti-rust oil can also affect the spreading of the anti-rust oil, so that the calculation accuracy of the kinematic viscosity of the anti-rust oil can be improved by modifying the thickness of the anti-rust oil film layer by adopting the temperature difference between the elevator guide rail and the anti-rust oil, and T2Can be obtained by directly heating or cooling when preparing the rust preventive oil.

is the kinematic viscosity, W, of the other components of the rust preventive oil except the diluentTThe weight portion of the components except the diluent is the total weight portion of the components of the rust preventive oil, and W is the weight portion of the diluent. Due to rarenessThe kinematic viscosity of the diluent is low, and the kinematic viscosity of the rust preventive oil can be reduced by the addition amount of the diluent.
