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

The electric property of natural rubber is a kind of non polar material, and it is a better insulating material. When the natural rubber vulcanization after the introduction of polarity factors, such as sulfur, accelerator, so that insulation performance.The dielectric properties of natural rubber are a nonpolar substance that is soluble in non-polar solvents and non-polar oils. Natural rubber is not resistant to cyclohexane, gasoline, benzene and other media, non vulcanized rubber can be dissolved in the above medium, vulcanized rubber swelling. Natural rubber insoluble in polar acetone, ethanol, more insoluble in water, resistant to 10% hydrofluoric acid, 20% hydrochloric acid, 30% sulfuric acid, 50% sodium hydroxide and so on.

Q:What are the types of hose connectors?

Joint classification of common are: expansion joints, quick couplings, withhold joints, removable fittings, compression fittings, flared joint is in welded joints.

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

The utility model relates to a pipe protecting sleeve, which is a new product replacing the traditional metal protecting spring used for the protection of traditional rubber hoses. Alias: hose sheath, rubber tube outside protection special nylon spiral sheath, etc..

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

Bending test: after bending the hose to a certain extent, measure the minimum outside diameter of the bending part and the ratio of the outside diameter before bending, the passing capacity of the steel ball and the bending force when the tube is pressurized.

Q:Plastic coated metal hose flexible conduit joint what treatment

You see what the other end is connected to the main, if the connecting hose can be used self fixed joints, if no thread connection pipe, to set joint by three column card, if the connection device or threaded pipe, external thread joint, and some fittings, Glenn joint

Q:Classification of metal hoses

Corrugated metal hose (abbreviated bellow) is a kind of high quality flexible pipe in modern industrial pipeline. The utility model is mainly composed of a corrugated pipe, a net sleeve and a joint. The inner pipe of the utility model is a thin wall stainless steel corrugated pipe with a spiral shape or an annular waveform, and the mesh cover of the outer layer of the corrugated pipe is made of stainless steel wires or steel strips according to certain parameters. The joint or flange at the ends of the hose is matched to the connector or flange of the customer's pipe.

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

Water supply equipment factory, the production of rubber soft joints, mainly used in water pump import and export, function: shock absorption, noise reduction, protection of pipes!

Q:What advantages does the Parker hose have in comparison with other hydraulic hoses?

Parker hose and other hydraulic hose advantages compared to:First: from the price point of view, the price of PAKER is the most expensive industry. High popularity.Second: if from the quality point of view, the quality of stability, high degree of recognition.Third: from the point of view of use, the difference is not obvious. PAKER things match well.Fourth: strong pressure resistance, rated 400bar hose, blasting pressure can reach close to 1000ba

Q:Does rubber hose drink from tap water? Is it poisonous?

.PVC is actually a vinyl polymerization substance, whose material is a non crystalline material. PVC materials often use stabilizers, lubricants, auxiliary processing agents, pigments, anti shock agents and other additives in practical use. Is not flammable, high strength, excellent resistance to climate variability and geometric stability. PVC has strong resistance to oxidizing agents, reducing agents and strong acids. However, it can be corroded by concentrated oxidizing acids such as concentrated sulfuric acid and concentrated nitric acid, and it is also not suitable for contact with aromatic hydrocarbons and chlorinated hydrocarbons. In addition, the terms person, vs, computer, abbreviated as PVC, and the PVC humanoid are often referred to as PVC.
