What are the advantages of ultra-high polymer crown wheel liners?

Classification:


【Summary description】The new material of the Tianlun lining block is a saturated molecular cluster structure, and has almost no branching and double bonds, as well as factors such as crystallinity. Therefore, its guide wheel lining block has stable performance and excellent corrosion resistance. It is a high-quality friction lining and a lining for mine hoists. It has its unique advantages and cannot be replaced by other liners. What should be paid attention to when installing the crown wheel gasket? Do you know what there are? If you're not sure, let's take a look together.

The new material of the Tianlun lining block is a saturated molecular cluster structure, and has almost no branching and double bonds, as well as factors such as crystallinity. Therefore, its guide wheel lining block has stable performance and excellent corrosion resistance. It is a high-quality friction lining and a lining for mine hoists. It has its unique advantages and cannot be replaced by other liners. What should be paid attention to when installing the crown wheel gasket? Do you know what there are? If you're not sure, let's take a look together.

What should be paid attention to when installing the crown wheel gasket?

1. It should be clean and free from oil stains.

2. It should be installed close to the shell and lining groove, and the welding seam of the crown wheel should not be padded with lining blocks. Both ends along its length direction should be compressed tightly. It is strictly prohibited to loosen the crown wheel pad from any direction.

3. The two and a half must maintain a high and close contact, without any unevenness or unevenness.

4. The initial position of the friction pad arrangement should be appropriate to ensure that the opening blocks of each pulley groove press against a complete friction pad, and the opening blocks should be tightened to ensure that the friction pad is pressed down. After replacing the cushion block of each pulley, the opening block must be pressed tightly in a timely manner.

What are the advantages of ultra-high polymer crown wheel liners?

1. Ultra high polymer crown blocks have advantages such as flame retardancy (flame retardant value above 40), high chemical resistance, good mechanical strength, and good electrical insulation. The physical and chemical properties of ultrahigh molecular are stable, insoluble in water, alcohol and gasoline, and the leakage of gas and steam is low: it can withstand less than 90% sulfuric acid, less than 50-60% caustic soda solution and 20% any concentration at normal temperature, and has certain chemical corrosion resistance. It is quite stable to salts, but soluble in organic solvents such as ethers, ketones, chlorinated aliphatic hydrocarbons, and aromatic hydrocarbons.

What are the characteristics of the crown wheel liner made of ultra-high polymer?

2. Good flame retardancy;

3. Excellent chemical corrosion resistance;

4. High mechanical strength;

5. Good stability; Electrical insulation.

6. KP-09 ultra high molecular weight crown has unparalleled wear resistance and impact resistance compared to other plastics due to its extremely high molecular weight. Comprehensive characteristics such as impact resistance, corrosion resistance, low temperature resistance, self-lubrication, and absorption of impact energy.

What are the advantages of installing the crown wheel gasket?

Low density, excellent chemical resistance, heat resistance, impact resistance, and odorless, it is currently one of the engineering plastics that meets environmental requirements. Mainly used for single rope mine hoists. Due to the severe wear of the rope groove caused by the lack of rope groove gaskets in some existing pulley components, the PP pulley gasket component has changed a significant amount of work to replace the entire pulley. This product is made of moisture-resistant materials and is more suitable for outdoor use as a crown gear. The service life is more than three times that of rubber conveyor belt liners and general plastic liners.
