Abstract

The invention provides a preparation method of an outer membrane of a steel plate or steel rail detection wheel and relates to the technical field of preparation of the outer membrane of the detection wheel. The preparation method comprises the following steps of: carrying out injection molding on a polyurethane material under the conditions that the temperature is 160-200 DEG C and the weight is 80-100 kilograms; and de-molding to obtain the outer membrane of the detection wheel. The preparation method disclosed by the invention is simple; the production time of a single product is short, the speed is fast, consumption reduction and energy conservation are realized, the cost is reduced, and the production efficiency and the economic benefits are improved; and the dialysis degree of the prepared outer membrane of the steel plate or steel rail detection wheel is good and the service life is long.

Description

technical field [0001] The invention relates to the technical field of preparation of the outer film of a detection wheel, in particular to a method for preparing the outer film of a steel plate or rail detection wheel. Background technique [0002] Existing steel plate, rail detection wheel outer film is generally made by the method for pouring. And my country's detection wheel outer membrane has been relying on imports. The existing preparation method has the following disadvantages: 1. The process is complicated, the energy consumption is high, and the cost is high. 2. Long production cycle, low output and poor dialysis degree (the material is polyether resin). 3. The detection result is not intuitive. 4. Production time: The production time of each product is 40-50 minutes. Contents of the invention [0003] The invention provides a method for preparing the outer film of a steel plate or rail detection wheel, which solves the problems of low production efficiency, ...
