Q:Three yuan ethylene propylene rubber joint (high temperature resistant rubber joint) can withstand high temperature

Because three yuan ethylene propylene rubber does not bear oil, the mechanical strength is low, the price is expensive, therefore it is not suitable to make the oil resistant sealing product.

Q:What's the cause of a default like a general rubber product?

Measures to prevent aging: from the point of view of aging, one of the main reasons is the polymer structure itself. Therefore, it is important to improve the structure of polymers to improve their aging ability. For example, in rubber vulcanization, there are still unsaturated double bonds, and rubber products in use and it is difficult to avoid the erosion of sunlight, oxygen, ozone, so people on the synthesis of new varieties, to avoid or reduce the polymer chain of rubber double bonds, such as ethylene and propylene two monomer by copolymerization made two yuan B two rubber, different from other synthetic rubber is one of the major characteristics in the structure of the backbone is not completely saturated with double bond, making it the most ozone resistance, chemical resistance, high temperature resistant rubber aging; there is a kind of antioxidant, such as adding oxygen or ozone to prevent aging caused by antioxidants. Add UV stabilizers, heat stabilizers, preservatives and other unfavorable factors, and caused by aging.

Q:Why can the air conditioning connection be made of copper tube? How about rubber tube and aluminium pipe? Please heroes pointing for the dishes.

The pressure of the aluminum pipe is relatively small. "Again, when the aluminum pipe is too soft, it is easy to be flattened.".. Rubber tubes will decay if they are used! Withstand pressure is also high!

Q:How can we prevent the aging of rubber tubes?

Formula design is the most important. Rubber formula design is directly related to the service life of the product!

Q:What does the letter of the high-pressure tubing connector mean?

Purpose: high pressure tubing tubing steel wire spiral reinforced layer and wear resistant synthetic rubber composition used for conveying high pressure, engineering machinery hydraulic oil, gas, petroleum, submarine irrigation, steel mills, chemical plants and other media.

Q:Is there a tolerance standard for rubber tubes in length?

Just think, in the use of the tube, is the important dimension of diameter and wall thickness of the pipe, a little a little long, short should not affect the use, especially the rubber tube, right?! so imagine, rubber tube should not have standard tolerances in length (requirements).

Q:The rubber tube of the gas cooker is aging. It's leaking. Can you change it for yourself?

You can change it yourself. However, many families do not yet know that in the past two years, the state has made great efforts to change rubber tubes into metal hoses, because metal hoses are safer, longer life and better sealing. They will certainly replace rubber pipes in the future.

Q:The gas water heater uses metal pipes and rubber pipes

Gas water heater using metal pipe, good heat resistance, no aging!

Q:Between the two flanges in the middle of the rubber tube, what is the name of the connection?

Rubber flexible joint is also called rubber flexible joint, flexible rubber joint, flexible rubber joint, rubber shock absorber and so on.

Q:What kind of material does hose screw protection cover have? What are their advantages and disadvantages?

The utility model relates to a pipe protecting sleeve, which is a new product replacing the traditional metal protecting spring used for the protection of traditional rubber hoses. Alias: hose sheath, rubber tube outside protection special nylon spiral sheath, etc..
