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:What are the pipes in the air conditioner?

1. compressor exhaust to condenser: compressor exhaust pipe, basically rubber tube;2. condenser to liquid storage dryer: condenser outlet pipe, usually with rubber tube;3., storage fluid dryer expansion valve: liquid storage fluid pipe, usually rubber tube, but also useful metal hard tube;4. evaporator ~ compressor suction: compressor suction pipe, basically with rubber tube.

Q:Difference between non-standard rubber joint and national standard rubber joint

GB and non standard. GB type rubber joint refers to the material selection and production in accordance with the relevant 02S404 or 02S312 standards of the Ministry of construction, and has strict requirements on flange thickness, flange thickness, diameter and thickness.

Q:What is a rubber core pulling method?

When in use, one end of the hose is sealed, and the other end is inflated. A method of sealing surface of the hose end foot will truncate 1--3 rubber canvas, and then the steel pipe with coarse thread surface (steel tube with iron seal welding hose end) insertion hole, and 20 wire and hose surface densely wrapped firmly, will head with tin welding wire. Then, the valve is connected to the end of the inflatable end.

Q:How can we prevent the aging of rubber tubes?

The second is the design of the structure of the rubber products (especially damping products), has a great relationship between aging and fatigue, should avoid stress concentration! If the product is good has been produced to prevent aging, more trouble! Can be sprayed on the rubber surface, spraying insulation polymer.

Q:What is the principle of communicating devices? What if the rubber tube is used as a connecting device to change the water for the fish?

The principle of communicating devices can be explained by liquid pressure. If the same liquid is contained in a U glass tube, a small liquid AB is conceived at the center of the bottom of the communicating device. If the liquid is stationary, it does not flow. The pressure of the liquid in the left tube toward the right side of the liquid AB must be equal to the pressure of the liquid in the right tube toward the left of the liquid AB. Because in the communicating vessel is filled with a liquid, the same two liquid column density, according to the formula of P= P GH liquid pressure that only when both sides is equal to the height of liquid column, the liquid column is equal to the pressure on both sides of the liquid film AB. Therefore, in the case of no flow of liquid, the liquid level in each vessel of the communicating device shall be kept flat. (ideal model method) the connecting device is characterized in that the liquid level in each container is flat only when the same liquid is contained in the container. If the container is tilted, the liquid in each container is about to begin to flow. One end of the liquid column flows to the lower end of the liquid column and stops flowing until the liquid level in each container is normal. As with rubber tube two glass tubes connected together in container with a liquid, which will be a fixed tube, the other tube up and down or tilt, can see the two tube level in stationary phase remained flat. The connecting device is provided with the same liquid, but the pressure on the liquid surface is unequal, and the pressure difference of the liquid surface is equal to the pressure difference produced by the liquid level difference of the two container of the communicating device.

Q:What are the rubber pipe joints perfectly joined to the pipe fittings?

Rubber tube joints are flanged in general. Thread.

Q:What is the rubber sleeve flange connection sleeve?

Rubber flexible joint flange connection sleeve flange gate valve quota.

Q:What kind of material is the rubber tube with acid, alkali and high temperature resistance made of?

To acid, but also high temperature resistant material, only silica gel can do. Silica gel has a high temperature resistant material, can be used at 300 degrees high temperature for a long time, instant high temperature can reach 350 degrees. It's Jiao Jiao in the rubber hose.

Q:There are several ways to connect the built-in rubber stop

Generally, there are two kinds of joint methods for this kind of rubber sealing strip: one is to use adhesive to make cold joint, and the other is to use hot vulcanizing mold to heat it.
