Abstract

The invention relates to a preparation technology of an outer membrane of a detection wheel, and particularly relates to a preparation method of an outer membrane of a steel plate or steel rail detection wheel. The following technical scheme is adopted: the preparation method comprises the following steps: injecting a polyurethane material into a mold of the outer membrane of a detection wheel, wherein the injection temperature is controlled to be 160-200 DEG C, the injection pressure is 80-100kg, and the pressure after stored materials are put in is 80-100kg, and demolding, thereby obtaining the outer membrane of the detection wheel. According to the invention, the preparation method of injection molding replaces the existing preparation method of pouring, the problem that operators are burned during processing by the pouring method is solved; the preparation method is completed by applying the injection molding mold, the safety coefficient of the production process is improved; the used tool has no drying requirement; the preparation technology is simplified; the industrial manufacture is easy; the production cycle of single products is short; the outer membrane of the steel plate or steel rail detection wheel is short in production cycle, high in yield, and good in dialysis degree.

Description

technical field [0001] The invention relates to a preparation process for a detection wheel outer film, in particular to a preparation method for a steel plate or rail detection wheel outer film. 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: the existing pouring process is complicated, consumes a lot of energy, and during the pouring process, liquid raw materials are often encountered, which is easy to burn the operator and has a high safety factor; and the existing During the pouring process, the tools used must be dry, which complicates the manufacturing process and is not conducive to industrialized manufacturing; the production cycle is long, the output is low, and the dialysis degree is poor (the material is polyether resin); the test result is int...
