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:What should I pay attention to when rubber tube is in storage?

Storage should be as follows: (1) should be stored in a ventilated and dry environment, the relative humidity of the air is 50% ~ 80%. (2) should be stored in non corrosive media, and away from the heat source, the temperature is about 5 degrees Celsius conditions. (3) packing should be kept as far as possible without box stacking.

Q:What are the categories of hose?

A rubber hose products structure: hose cloth; woven hose (fiber braided hose, steel wire braided hose); winding hose (fiber winding hose, hose winding wire); knitted hose, hose and other circular weaving hose (rubber hose, rubber and plastic composite hose and hose, drilling hose, etc.).

Q:Rubber soft joint, what brand of good, the best price is more reasonable. Don't say anything expensive.

There are many kinds of rubber joint products produced in the West Village of Gongyi. The prices are high and low,Gongyi Kin Kun water supply equipment factory produces rubber soft joints all year round

Q:Why should the high pressure hydraulic tube peel off the outer skin?

Reasons for stripping:1, the inner diameter of the sleeve is a standard series, and a little rubber hose is not suitable for sizing.2, after stripping, the sleeve can be directly pressed on the steel wire layer, the connection is reliable, and it is not easy to pull out.

Q:What is the function between the rubber pipe joint and the installing pipe?

The action of the rubber pipe joint on the installation of pipes:1. Small size, light weight, good elasticity, easy installation and maintenance.2. After installation, the transverse, axial and angular displacement of the pipe vibration can be absorbed. The pipe is not concentric and the flange is not parallel.3 、 after installation, it can reduce the noise caused by vibration of pipes, pumps and so on, and has strong vibration absorption ability.

Q:M40 and M50, and then the hose is 2 "what does the box connection mean?"

One with teeth and one with hose, the hose is 2 inches, 2 inches of hose, and the inner hole is 50MM (1 inches =25.4MM).

Q:Why does Br2 corrode rubber tubes?

Bromine elements need to be sealed with water to prevent steam escaping and harm the human body. Oxidizing, there are a variety of variable valency, under normal temperature and weak water reaction, generating hydrobromic acid and bromate. Heating increases the speed of reaction. Hydrobromide is a strong acid with an acid stronger than that of hydrogen chloride. Bromine is commonly used in organic synthesis.

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: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.
