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:Do you need a hose connection to connect the ventilation pipe to the exhaust fan? Under what circumstances? Under what circumstances?

Ventilation ducts and exhaust fans are for people or things, and the noise of vibration is unbearable for people or things.

Q:What is the maximum pressure that a hose can bear?

This hose with material, wall thickness, diameter is Dudu, but there are special hose pressure testing machine test the size of the market, you take a look at the next.

Q:Flex rubber joint installation skills, what are the materials of rubber soft joint?

Rubber soft joint material:Ordinary water, acid and alkali resistant, oil resistant rubber, high temperature resistance, low temperature resistance

Q:Hydraulic hose joint configuration

Gas safety hose joint: a joint security guarantee gas transmission, including metal hose, Baotou, connecting pipe and a connecting nut, one end of the connecting pipe and hose, metal hoop pressure Baotou into one, the other end is connected with the inner hole of flange nut for different aperture of two parts, large hole diameter is slightly larger than the connection the flange is provided with internal thread, big hole depth is larger than the thickness of flange, hole diameter is slightly larger than the connecting pipe outer diameter and smaller than the outside diameter of the flange.

Q:The small hose attached to the grease gun is coarse or fine at the joint

For sealing, according to the maze principle, the smaller the pitch, the number of threads, that is, the more layers, the better the sealing effect, not easy to leak oil, significantly better than the rental thread.

Q:How can the tightness of rubber tube and metal pipe joint be ensured?

To see what kind of material hose, small 1MM~2MM, if the inner pressure then add hoop.

Q:How should we distinguish between the silicone hose and the rubber tube?

Smell, silicone no flavor, rubber flavor, silicone general flexibility better, rubber mechanical better

Q:Can high speed air flow through a rubber tube and produce static electricity?

It is not easy to describe the magnitude of the voltage generated by the static electricity of these aggregates, which is related to the humidity, velocity, characteristics of the rubber material, and the surrounding environment.

Q:Petroleum gas has a corrosive effect on ordinary rubber pipes and is easy to cause air leakage. So, what kind of hose must be used?

In order to remind people of the leakage of liquefied petroleum gas in a timely manner, the processing plant often mixes a small amount of foul odor mercaptan or thioether compounds into liquefied petroleum gas, which is the source of special odor.
