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

It's aging of rubberAging refers to the polymer materials (including rubber, plastics, fiber and so on) in the processing, storage and use of the process, due to the comprehensive effect of internal and external factors, its performance gradually deteriorated, resulting in the final loss of use value.

Q:What should I pay attention to when rubber tube is in storage?

The phenomenon of natural vulcanization caused by long-term exposure to corrosive gas or prolonged exposure to sunlight is called aging of rubber. The main phenomena are increasing of self weight, volume expansion and strength reduction.

Q:What are the production processes and characteristics of high pressure rubber hose?

High pressure wire braided hose production process: rubber, rubber mixing, extrusion, heat pipe casing (core casing, silicone oil and then wipe) molding glue, woven wire (wire stranding), package glue, water reel cloth, cloth, water solution of vulcanization, mandrel stripping, cutting head, pressure test and inspection packaging and warehousing.

Q:What do you mean by "DN" on hydraulic hose?

DN stands for nominal diameter. The standard diameter after standardization, the midpoint between the inner diameter and the outer diameter, in units mm.

Q:What are the materials used in rubber joints? What are their advantages?

Ordinary air, compressed air, water, sea water, hot water, weak acid, strong alkali, temperature between -20 ~ +115, such as the media with ordinary natural glue can

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

Reasons for stripping:1, the inner diameter of the sleeve is a standard series, and a little rubber hose is not suitable for sizing.2, after stripping, the sleeve can be directly pressed on the steel wire layer, the connection is reliable, and it is not easy to pull out.

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?

The interface method should be carried out according to the following procedures: DN400 pipeline and below, by a man with a cotton rope hook is installed pipe socket, the other one with a long lever oblique insertion based cross baffle against the tube end of the center position, and then forced the tube slowly into after the installation of HDPE double wall corrugated pipe the pipe socket to a predetermined position; more than two sets of DN400 pipeline by hand hoist will pull in pipe section. When the interface is closed, the spanner on both sides of the pipe section shall be pulled synchronously, so that the rubber sealing ring is properly positioned and is not distorted or not falling off.

Q:Is the metal hose the same as the soft connection?

One hundred and eight thousand in the metal hose and PVC casing, installation of on-line outside for protection, metal hose used in the instrument signal line, the soft connection is on the main circuit element used to protect the main loop stiffness damage loop, such as motor and pump connected with a soft connection,

Q:How do you remove the burrs on the rubber joint quickly?

Frozen deburring machine is a kind of ultra low temperature using liquid nitrogen to make rubber, plastic products, zinc alloy burr occurs rapidly embrittlement, and under this condition, the burr of high-speed jet impinging particles of frozen products, so as to achieve both high quality and high efficiency removal products of burr, and keep possession the product itself does not change. The utility model can greatly improve the deburring precision of products, and has a high degree of intensification.

Q:How to identify the quality of rubber pipes for sewage treatment?

The general hose inside and outside the adhesive layer material with natural rubber, styrene butadiene rubber or butadiene rubber; hose with chloroprene rubber, nitrile rubber; acid and alkali resistant, high temperature resistant hose with ethylene propylene rubber, fluorine rubber or silicone rubber etc.. Structure: hose structure is usually divided into inner layer, outer layer and skeleton layer (or middle layer). The inner layer directly bears the abrasion and erosion of the conveying medium; the outer rubber layer protects the inner part of the hose from the damage and erosion of the external environment; the stock price is the pressure bearing layer of the rubber tube, and gives the strength and rigidity of the tube body. The working pressure of the hose depends on the material and structure of the skeleton.
