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

The main use of natural rubber natural rubber because of its insulation, plasticity, water vapor barrier, tensile and wear characteristics of strong elasticity and good, widely used in industry, agriculture, national defense, traffic, transportation, machinery manufacturing, medical and health fields and daily life, such as transportation with the tire industry; with the transport belt, transmission belt, sealing rings; medical gloves, transfusion tube; used in the daily life of the shoes, raincoats, warm water bag are rubber as the main raw materials manufacturing, defense on the use of aircraft, artillery, tanks, and cutting-edge technology in the field of rockets, satellites, spacecraft, space shuttle requires a large amount of rubber parts.

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?

It can not be installed, but it does not conform to the standard of chemical experiment operation. Strong oxidizer will damage rubber tube. That's why it's not recommended. Acid burette operating standards have placed solution requirements.

Q:What is the difference between the precast beam of the bridge and the method of pulling out the rubber tube after pouring the concrete? What's the difference between design and calculation?

Construction process, in order to avoid concrete into bellows, influence later wear steel strand, construction units generally use PVC and other rubber tube into bellows, in order to double insurance, don't let concrete into. Its length is certainly larger than the length of bellows (750mm at one end for easy operation)

Q:Will the outside of the brake hose of the car burst apart?

There is a potential safety hazard to the outside rubber skin. It is possible to slam on the brake. The brakes are not trivial, so I suggest you replace them in time.

Q:Hydraulic hose joint configuration

Strong uplift: hose connector is composed of a core tube and sheathed and clamped together with the sleeve, the sleeve is divided into two sections, the first section length is less than second and greater than the outer diameter of section second; the core tube is divided into two sections, the first section is the second section is the joint oil, rubber press section; the core pipe and the sleeve rubber press section cooperation is divided into three parts. The first part is a locking part, the second part is the part of the third part is the steel wire buckle, rubber press sealing parts; in the first part, the outer surface of the core pipe has a clamping groove, the sleeve surface along the circumferential direction with a snap ring matched; in the second part, the core tube the outer surface of a step and a groove, the inner surface of the sleeve ring a match; in the third part, the outer surface of the core pipe is provided with at least two corrugated groove, the sleeve surface is provided with at least two teeth groove. The utility model is used for the steel wire woven hose made of inner rubber layer, steel wire layer and outer rubber layer, and has the advantages of excellent pull proof performance, long service life and good sealing performance.

Q:How do the automobile rubber hoses combine with the quick couplings?

Turn the rotary handle on the quick connector to the open position first;

Q:My company does high-quality rubber tube, all of the core method, and why use EPDM to do the inner tube, it is difficult to take off the core, please point out! What's the reason?

The core needs to be removed, and if it is too long, the mandrel can be divided into two sections and separated from the 2 sides

Q:What happened to the soft rubber flat?

A slightly heated or pressurized medium will return to its original condition.

Q:The principle of the common bicycle valve

An elastic thin edge hose is placed below to form the whole of the core. In fact, it is a one-way valve. When inflating the bicycle tyre, the compressed air in the air pump enters the valve core from the hollow part, and the elastic rubber tube is top, and the air enters the tyre.

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

The electric water heater, now in the industry are required to use PPR on the inlet and outlet pipe welding, a long service life, can effectively control the water heater outlet Water Leakage; on the other hand, can avoid the water heater power switch for two grounding and frequent take-off effectively. Therefore, the metal pipe connection does not meet the safety and installation specifications
