Problems solved by technology

However, due to the closeness of the colors between the various parts of the tire, the gray level difference between different parts is very small, and the boundaries between the parts are highly fuzzy, which leads to certain difficulties in the boundary confirmation between different parts and the extraction of measurement targets.

Embodiment 1

[0022] Process of the present invention:

[0023] 1. Use a section cutting machine to cut out the section required for analysis. The size of the section is guaranteed to be placed in a container that meets the requirements, and the section has a complete analysis interface, such as figure 1 shown;

[0024] 2. Select ordinary sulfur powder (non-oil-filled), put it in a container with good heat conduction, and cover the container. Put the container in a constant temperature oil bath with stirring function, set the temperature of the oil bath at 120°C, and turn on the stirring function;

[0025] 3. After the sulfur is fully dissolved, place the cross-section in the sulfur solution, keep the oil bath at 120°C and stir, and treat for 24 hours;

[0026] 4. After the treated section is stored under laboratory conditions (temperature: 24°C, humidity: 52% RH) for 24 hours, use a grinder with a grinding wheel particle size of 40um to grind the surface of the section until the surface ...

Embodiment 2

[0029] Except that sulfur adopts 10% oil-extended sulfur powder, all the other processes are consistent with embodiment 1.

[0030] Cross-sections before and after treatment image 3 As shown, after the section is processed, the interface fuzziness is improved.

Abstract

The invention belongs to the field of rubber tire manufacturing, and particularly relates to a tire section sample treatment method and a sample obtained through the method. According to the invention, the method comprises: cutting a section through a tire to obtain a tire section sample, immersing the section of the tire section sample in a sulfur powder or 10% or less oil-filled sulfur powder melt for treatment, and polishing the section until the surface is flat and smooth after the treatment is completed. According to the method, the tire section is treated through the sulfur solution, sothat the color difference among components is improved, the boundary fuzziness among the components of the section is reduced, and the tire section which is easier to analyze is obtained.

Description

technical field [0001] The invention belongs to the field of rubber tire manufacture, in particular to a method for processing tire section samples and samples obtained by the method. Background technique [0002] Tires are one of the most important parts of a car, carrying the car's weight and transmitting traction and braking forces. With the continuous increase of car ownership, the output of tires continues to increase, and new tire products continue to increase. During the development of new tires and tire production, the cutting and analysis of tire cross-sections are essential. [0003] Tire section cutting can be done manually or by machine. However, since the bead wire and steel cord in radial tires are difficult to cut, machine cutting is often used at present. In the process of tire new product development, production monitoring, and abnormal production analysis, tire section analysis is one of the indispensable means and methods. First of all, the difference b...
