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

Rubber aging is a common problem of rubber products, and aging is mainly due to internal structure or component is easy to aging due to weakness, such as unsaturated double bond, branched, carbonyl, hydroxyl and so on; at the end, the main external or environmental factors are sunlight, oxygen, ozone, heat, water and mechanical stress force, high energy radiation, electricity, industrial gas, water, salt fog, fungi, bacteria, insects etc..

Q:Three yuan ethylene propylene rubber tube covered with nylon PA66, what glue can not afford the layer?

Because the nylon 66 excellent heat resistance, chemical resistance, strength and convenient processing, so it has been widely used in the automotive industry, currently has almost all parts for automobile, such as engine parts, electrical parts and body parts.

Q:What is a hose valve?

[hose valve features]1, abrasion resistance, corrosion resistance, frost resistance, sealing performance, and only the replacement of rubber sets, that is, as good as new, the valve body can be used permanently, life expectancy is 4-6 times the ordinary valve.2, sealing special good: both ends of the hose with rubber flange, when the valve and pipe connection, no need to seal the gasket, thereby eliminating the running, risk, drip, leakage and other undesirable phenomena.3, good cold resistant performance: the fluid flow in the flexible hose, thereby eliminating fluid crystallization caused by evil shell cracking.4, scientific and reasonable structure, simple operation and flexible, convenient maintenance, maintenance, as long as the replacement hose, valve and other institutions can be used for a long time, thereby improving the service life of the valve, greatly saves the production cost of the user, in line with value engineering.5, the valve structure is simple, is the only non leakage valve, capable of a variety of medium concentrations of acid and any concentration of alkali salt solution, can transport pulp, dry and wet powder, as well as crystal object medium.6, different media can choose different rubber formula hose, to meet the needs of different users.

Q:Can black soft rubber pipes be used as water pipes? Why is there a pungent odor?

If you have a strong smell, it must be made of reclaimed gum, and it's inferior reclaimed gum. You smell the smell of reclaimed tar.

Q:What are the gas hoses?

Go straight to the gas.There are 2 kinds of gas hose: one is made of black rubber thickened tube, and the other is stainless steel hose.Stainless steel hose is better, more than 10 years of life. Basically don't use it.Rubber life of 1 and a half years, 2 years later aging brittle, need to change.

Q:What is negative pressure rubber shock proof joint? Is vacuum piping available?

With high pressure, good elasticity, large displacement, balance pipe deviation, absorbing vibration and noise reduction effect, convenient installation, but also can greatly reduce the noise and vibration of the pipeline system, which can solve all kinds of line interface displacement fundamentally, axial expansion and concentricity problems, mainly installed in the pump inlet the vacuum pump inlet, or large, can solve the 100% rubber joint suction flat phenomenon.

Q:How do the automobile rubber hoses combine with the quick couplings?

Turn the rotary handle on the quick connector to the open position first;

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

Hose cover is usually made of nylon or polyethylene

Q:What does rubber soft joint "KDTF" mean?

KDFT flexible single ball rubber joints of rubber joints, rubber flexible connector is made of fabric reinforced rubber parts and flat joint, loose metal flange or threaded pipe flange, joint for pipe vibration noise reduction, displacement compensation.

Q:Why does Br2 corrode rubber tubes?

Br2 bromine gasBr2 bromine element at room temperature is dark brown liquid, soluble in water, 100g water can dissolve about 3G bromine. Highly volatile, toxic, steam strongly stimulate the eyes, mucous membranes and so on. The water solution is called bromine.
