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

The product is mainly composed of inner and outer rubber layer, cord fabric and steel wire ring. It is formed by vulcanizing with metal flange at high temperature and high pressure

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

High temperature rubber joint adopts three yuan ethylene propylene rubber processing, can withstand high temperature 140 degrees, if need higher temperature, need to use fluorine rubber, the highest temperature can reach 200 degrees!

Q:The maximum number of joints for a rubber hose is no more than

Shower hose, shower hose, two joints are nominal diameter of: 1/2 inch (4 thiophene) cylindrical pipe thread. Standard component. Hot and cold bath: take a bath with hot water before going to bed every day. The temperature of the water is within the limits of the body's tolerance. After washing, sleep in hot water for 15 minutes. After bathing was out of a sweat, after 3~4 minutes, and then into a basin of cold water or cold shower. Note that the hot and cold bath must be "hot before cold."".

Q:Which is better for binding files with rubber tubes and cotton threads?

In fact, the most suitable binding file is the file department I twine, such units are preserved, just to have you asked, hope to adopt

Q:Acid burette and burette why different structure

The reason is that the glass is acid resistant, but it is caustic.

Q:Plastic coated metal hose flexible conduit joint what treatment

Joints are generally zinc alloy material, the surface can be plated hard chromium treatment, plastic pipes and many types of joints can match

Q:Is the rubber pipe joint installed in the middle of the pipe and pump for shock absorption?

Control the noise produced by parts of machinery, equipment, and equipment. The pump foundation of the new pump house should adopt heavy weight to prevent vibration from producing noise. Vibration isolation should be set up with rubber vibration isolating pads to reduce vibration noise. Each pump unit shall be provided with a foundation to prevent resonance. Use "soft" connection as far as possible in the suction pipe and pressure pipe of the pump. Periodic maintenance problems, such as packing leakage, equipment parts loose, serious wear and tear of equipment parts, mechanical vibration and so on, should be repaired in time, thereby reducing noise.

Q:What about leakage of hose joint?

No matter what kind of pipe joint leaks, you can repair the hose with a special adhesive tape for temporary repairs. Specific operation method is: first, close the valve after the water is cut off, open the faucet to the appropriate position to release most of pressure inside the pipe and then use special tape tied Water Leakage parts, or with epoxy adhesive to seal.

Q:Will the electric water heater be well connected with metal hose or hose?

On the other hand, the utility model can effectively avoid the frequent switch of the water heater power switch because of the two grounding. Therefore, the metal pipe connection does not meet the safety and installation specifications.
