Q:What is the essential difference between natural rubber and three yuan ethylene propylene rubber?

The strength of natural rubber in the elastic material, natural rubber, rubber, rubber, vulcanized rubber with higher intensity. The tensile strength of uncured rubber is called Green strength, and the Green strength of natural rubber is up to 1.4~2.5Mpa. The proper Green strength is necessary for rubber processing and forming. The tear strength of natural rubber is also higher, up to 98kN/m, and its abrasion resistance is better. The reason for the high mechanical strength of natural rubber is that it is self reinforcing rubber. When stretched, the macromolecule chains tend to form crystals in the direction of stress.

Q:What's the smell of petrol in the car and the trunk?! Especially after a long drive!

Leaks sometimes occur at the interface of the gasoline pipe, and then gasoline fumes may enter the vehicle through the air-conditioning system. If gasoline is found in the car, check the interface of the fuel line. It's easy to see just open the hood. Because once the leakage occurs, a long time will appear in the surface of a layer of sludge. This problem is also good to solve, as long as the interface is tightened or repaired, just OK!

Q:What's the rubber sleeve of the expander?

Rubber joint called flexible rubber joint, soft rubber joints, rubber flexible joint, flexible joint, shock absorber, shock absorber, shock absorber pipe throat, is a kind of high elasticity, high air tightness, pipe joint resistance to medium and climate. The product uses rubber elasticity, high air tightness, medium resistance, weather resistance and radiation resistance etc., using polyester cord fabric skew high strength, strong stability and the hot and cold composite, after high pressure, mold temperature and curing.

Q:Can the rubber hose for the LPG cooker and gas cooker be general?

Whether the gas stove is the use of natural gas or liquefied gas, artificial gas, all can use the rubber tube, need to pay attention to is the pipe diameter and gas stove pipe diameter should be consistent, but also to the fixed ring frame with rubber tube, rubber tube is also too long existing problem of aging time, while the gas is there is a certain danger, recommend regular replacement of rubber tube

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

High pressure hose is generally relatively thick, there are steel wire layer, the purpose of peeling is to connect the tooth and steel layer close combination, the joint is more solid. But not all high-pressure hose needs peeling. Now many large companies do not need peeling. For example, pike.

Q:Hose connector JB1885-77 what is the standard?

GB A flat joint core series hose assembly standard.

Q:The basement of submersible sewage pump outlet pipe installation need and flexible rubber joint is not installed? Can not?

Rubber joint, also called shock proof throat, is mainly used in the entrance and exit of pumps. It is used to absorb the noise caused by vibration during the operation of pumps.

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:How often do the oil - resistant rubber pipes undergo atmospheric pressure testing?

Low temperature bending test at low temperature: hose clamp on rigid torsion wheel diameter hose diameter 12 times, for 6 hours at a low temperature, twisted 180 degrees within 12s when the measured torque and the standard temperature measured torque ratio. Low temperature bending: hose clamped in the diameter of the hose within 12 times the torsion wheel, parked at low temperatures for 24 hours, in the 10s to reverse 180 degrees, check whether or not the internal and external plastic brittle fracture and damage. Test of low temperature brittleness measurement hose is the most simple specimen should be bent 90 degrees at low temperature, or a hose after freezing compressed 1/2 to see whether the embrittlement, another method is to use a certain weight of the heavy hammer falls freely, to see if the specimen embrittlement impact specimen.

Q:Natural gas can be connected to a gas cooker. Can rubber tube be used?

No, it's not safe. To purchase national standards products with 3C certification.
