Composition of negative pressure resistant pneumatic hose

阅读更多

Negative pressure resistant pneumatic hose is a hose used to transport liquid or gas, which has excellent pressure resistance and can withstand high pressure and negative pressure. In the fields of industry, agriculture, construction and household, negative pressure resistant pneumatic hoses are widely used. This article will introduce the composition, application and advantages of negative pressure resistant pneumatic hose.

First, the composition of the negative pressure pneumatic hose

Negative pressure resistant pneumatic hose usually consists of inner layer, reinforced layer and outer layer. The inner layer is made of special rubber material, which has good corrosion resistance and wear resistance, and can withstand the corrosion of various liquids and gases. The reinforcement layer provides strong support and pressure resistance, and can withstand high pressure and negative pressure. The outer layer has a good appearance and wear resistance.

1. Inner layer

The inner layer is the inner wall of the negative pressure resistant pneumatic hose, usually made of rubber material. The quality of the inner layer directly determines the quality of the entire negative pressure resistant pneumatic hose. The high-quality inner layer material can ensure the strength and durability of the negative pressure resistant pneumatic hose. The inner layer is made of special rubber material, which has good corrosion resistance and wear resistance, and can withstand the corrosion of various liquids and gases. Generally speaking, the inner layer materials are neoprene, butyl rubber, EPDM, etc.

2. Enhancement layer

The reinforcement layer is located between the inner and outer layers and is usually made of high-strength synthetic fiber material or steel mesh. The reinforcement layer is the core part of the negative pressure resistant pneumatic hose, and its function is to provide support and pressure resistance. The reinforcement layer can withstand high pressure and negative pressure, thus ensuring the safety of the negative pressure resistant pneumatic hose. Materials for the reinforcement layer include polyester, polyamide, steel mesh, etc.

3. Outer layer

The outer layer is the outer covering layer of the negative pressure resistant pneumatic hose, usually made of wear-resistant rubber or plastic material. The outer layer is the protective layer of the negative pressure resistant pneumatic hose, which can effectively prevent the negative pressure resistant pneumatic hose from being damaged by the external environment. The material of the outer layer is neoprene, butyl rubber, ethylene-propylene rubber, polyurethane, polyethylene, etc.

Second, the application of negative pressure pneumatic hose

Negative pressure resistant pneumatic hoses are widely used in industries, agriculture, construction and households. It can be used to transport various liquids and gases, such as water, oil, air, nitrogen, ethanol, acid and alkali liquids, etc. In the industrial field, it is often used to transport various chemicals and petroleum products, such as oil, natural gas, diesel, gasoline, liquefied petroleum gas, etc. In the field of agriculture, it can be used for irrigation, spraying, discharge, etc. In the field of construction, it can be used to convey construction materials such as cement and concrete. In the domestic field, it can be used for cleaning, spraying, irrigation and other aspects of work.

Third, the advantages of negative pressure pneumatic hose

1. Good pressure resistance

Negative pressure resistant pneumatic hose has good pressure resistance and can withstand high pressure and negative pressure. The reinforcement layer of the negative pressure resistant pneumatic hose is made of high-strength synthetic fiber material or steel wire mesh, which can withstand high pressure and negative pressure, thus ensuring the safety of the negative pressure resistant pneumatic hose.

2. Good corrosion resistance

The inner layer of negative pressure resistant pneumatic hose is made of special rubber material, which has good corrosion resistance. It can withstand the corrosion of various liquids and gases, thus ensuring the service life of the negative pressure resistant pneumatic hose.

3. Good wear resistance

The outer layer of the negative pressure resistant pneumatic hose is made of wear-resistant material, which can effectively prevent the negative pressure resistant pneumatic hose from being damaged by the external environment. The materials of the outer layer include neoprene, butyl rubber, ethylene-propylene rubber, polyurethane, polyethylene, etc., which have good wear resistance.

4. Safe and reliable

The negative pressure resistant pneumatic hose has good safety performance and can ensure the safety of the transportation process. The reinforcement layer can withstand high pressure and negative pressure, thus ensuring the safety of the negative pressure resistant pneumatic hose.

5. Portable and flexible

The negative pressure resistant pneumatic hose is small in size and light in weight, making it easy to carry and install. At the same time, the negative pressure-resistant pneumatic hose has good flexibility, can be bent freely, is not easily restricted, and is easy to use.

In short, the negative pressure resistant pneumatic hose is a very important industrial product with broad application prospects. It can not only improve work efficiency, but also reduce transportation costs and labor costs. At the same time, it can effectively protect the environment and human health. Therefore, for industries that need to transport liquid or gas, it is very necessary to choose a reliable negative pressure resistant pneumatic hose.
