Gansu sampled rubber products pass rate of 70%

The quality supervision and spot checks of rubber products recently announced by the Quality Supervision Bureau of Gansu Province showed that the sampling inspection rate of products was 70%.

This time spotted 40 batches of products from 34 companies. The main product categories involved were rubber sheets for industrial use, general V-belts for general transmission, tires for electric vehicles, inner tubes for electric vehicles, and rubber hoses for general water transport fabrics. Products.

The results showed that 28 batches of products from 22 companies were qualified, the qualification rate of the company was 64.7%, and the sampling inspection pass rate was 70%. The overall quality levels of the three products of Lifan tires, inner tubes for power trains, and ordinary V-belts were used. Stability, high pass rate, and poor quality of general-purpose water delivery fabric reinforced rubber hoses.

The main quality problems discovered by the spot inspection were: the tensile strength of the rubber hose, the inner and outer adhesive layers, the elongation at break, the inner and outer adhesive layers, the heat aging properties, the rate of change in tensile strength, the inner and outer layers, The thermal aging performance, the rate of change in the elongation at break, the internal and external adhesive layers are unqualified, and the indicators such as tensile strength, thickness deviation, and elongation at break of industrial rubber sheets are unqualified; The adhesive strength of the rope is not qualified.

Anti-bending Connector

Anti-bending connector is a special connecting tool for overhead transmission line stringing construction, which is used to link guide rope and traction rope in the traction and laying process. The anti-bending connector does not damage the rope, and can bear large bending moment without deformation and damage under rated load. It can pass the traction machine drum and tension wheel of the tension machine, as well as various paying off pulleys. It has the characteristics of small volume, light weight, high strength, round shape, convenient assembly and disassembly.

The anti-bending connector bears the tension through the U-ring and the bolt pin shaft covered with a stick to connect the two ends of the traction rope and insert the lock catch. It is made of high-strength alloy steel by integral forging and heat treatment. Its material has excellent tensile and bending resistance. Its external dimension is short and compact. When it bears radial load, the force arm is short and the bending moment is small.

Points for attention:

1. It is forbidden to overload the anti-bending connector.

2. Before using the anti-bending connector, check and confirm that all parts are in good condition.

3. When the anti-bending connector is used, the roller must be installed, the pin of the acid complex shaft should be tightened, and it can swing flexibly after connection.

4. The anti-bending connector shall not be mixed with corrosive articles to avoid corrosion.
