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

The glass transition temperature of natural rubber is -72 Deg. C, plastic flow temperature is 130 degrees centigrade, start decomposition temperature is 200 degrees centigrade, intense decomposition temperature of 270 DEG C. When natural rubber is vulcanized, its Tg rises, and no more viscous flow occurs.

Q:Do I need a shim for the flat metal hose joint?

If the two connections are flat, they must be placed gaskets, usually with PTFE gasket.

Q:The basic buret is a rubber tube is inlaid with a glass bead to replace glass piston. Why this burets cannot be used to install Potassium Permanganate solution?

The rubber tube can be Potassium Permanganate oxidation

Q:Three yuan ethylene propylene rubber hose, hydraulic oil and oil?

Finally, NBR (Ding Jing rubber), ACM (acrylate), FKM (FKM) can be non polar medium.

Q:HDPE double wall corrugated pipe joint shall be made of elastic sealing rubber ring and socket joint interface. What are the requirements for rubber ring joint?

When the interface is made, the inner wall of the bearing mouth is cleaned first, and the lubricant is coated on the inner wall of the socket and the rubber ring of the socket, and then the central axis of the socket face end is aligned.

Q:What is the essential difference between rubber expansion joint and rubber joint?

Rubber joint is a kind of pipe joint with high elasticity, high air tightness, medium resistance and weather resistance. 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. As the rubber joint has good comprehensive performance, it mainly acts as shock absorption, noise elimination and noise reduction. Therefore, it is widely used in chemical, construction, water supply, drainage, petroleum, light and heavy industries, freezing, sanitation, plumbing, fire fighting, power and other infrastructure projects.

Q:How to determine the tensile strength of GB rubber joint?

In the middle of the specimen, 4 parallel lines marked by the mark mark are used to mark two distances equal to the standard distance (type 1 is 25mm, type 2 is 20mm, and type 3 is lOmm), and each reticle shall be equidistant from the center of the sample. If the non-contact deformation measuring device is used, the proper marking device shall be used, and two parallel markings shall be placed on the narrow parallel part of the sample. Each mark shall be equidistant from the specimen center and perpendicular to the long axis of the specimen, and the specimen shall not deform during the marking.Style cutting, punching machine blanking note the above points, is to test the tensile strength of rubber joints based on, but also guarantee.

Q:Hose wire is it? What's the function?

Hose steel wire is used for processing rubber pipe galvanized steel wire, generally divided into two kinds, one of the main skeleton material used,

Q:Standard for implementation of type KXT-1 rubber joints

Rubber joint is also called soft rubber pipe joint, flexible rubber joint, soft rubber joints, rubber joints, high-pressure rubber joints, rubber shock absorber, compensator.

Q:Is the installation of submersible pumps mandatory for the installation of flexible rubber joints?

Deep well submersible pump must be equipped with steel pipe, water pipe.Submersible submersible pump, such as submersible sewage pump, according to the use of requirements, consider whether to install the flange connection form, Song River rubber soft joint, so it is not necessary.
