Q:The newly purchased natural rubber tube is too large. How can it be removed?

Can buy some activated carbon in the box, the cost is not high, but also long lasting odor.00 grams of black tea bubble into the two washbasin hot water, dumbbells, rubber flavor placed in the pot, and open the window ventilation, 48 hours, dumbbell rubber flavor will be down more than 90%, the pungent odor is basically eliminated. - buy 800 grams of granular activated carbon, formaldehyde.

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

Measures to prevent aging: from the point of view of aging, one of the main reasons is the polymer structure itself. Therefore, it is important to improve the structure of polymers to improve their aging ability. For example, in rubber vulcanization, there are still unsaturated double bonds, and rubber products in use and it is difficult to avoid the erosion of sunlight, oxygen, ozone, so people on the synthesis of new varieties, to avoid or reduce the polymer chain of rubber double bonds, such as ethylene and propylene two monomer by copolymerization made two yuan B two rubber, different from other synthetic rubber is one of the major characteristics in the structure of the backbone is not completely saturated with double bond, making it the most ozone resistance, chemical resistance, high temperature resistant rubber aging; there is a kind of antioxidant, such as adding oxygen or ozone to prevent aging caused by antioxidants. Add UV stabilizers, heat stabilizers, preservatives and other unfavorable factors, and caused by aging.

Q:Installation of rubber flexible joint

The pipe must have a fixed support or fixed bracket, and the force of the stationary bracket must be greater than the axial force. Vertical installation and overhead installation products both ends need to install the corresponding fixed bracket and force support, to prevent the compression of.

Q:Is the rubber pipe joint installed in the middle of the pipe and pump to absorb the shock?

A pump is a machine that transports liquids or pumps liquids. It will be the prime mover of the mechanical energy or other external energy transfer to the liquid, the liquid energy increase, mainly used to transport liquids including water, oil, alkali liquid, emulsion, suspension emulsion and liquid metal, but also transport liquid, gas mixtures and liquids containing suspended solids. Pump performance of technical parameters are flow, suction, lift, shaft power, water power, efficiency, etc.; according to the different principles of work can be divided into volume pumps, vane pumps and other types. Displacement pump is to use its studio volume changes to transfer energy; vane pump is to use the rotating blade and water interaction to transfer energy, there are centrifugal pumps, axial flow pumps and mixed flow pumps and other types.

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

While the three EPDM is ethylene propylene diene hydrocarbon, and non yoke of three yuan is the main characteristic of copolymer, excellent oxidation resistance, ozone resistance and anti erosion ability, also has excellent curing characteristics. Simple speaking is resistant to high temperature.The nitrile rubber by emulsion polymerization at low temperature, excellent oil resistance, high abrasion resistant, good heat resistance, strong adhesion. (oil).

Q:What are the properties of stainless steel metal hose materials?

The stainless steel metal hose is made up of corrugated pipe, stainless steel braid net and two ends joint.

Q:The pipe of the gas water heater is buried in the wall. It is made of nylon tube and rubber tube. Is it possible to use rubber tube?

Plastic pipes and rubber pipes are available, but the length, time and conditions are clearly defined.

Q:How to make a rubber tube requires flow

The characteristics of the rubber tube has physiological inertia, UV resistance, ozone resistance, resistance to high temperature (-80 to 300), high transparency, strong resilience, resistant to compression permanent deformation, oil resistance, impact resistance, acid and alkali resistance, wear resistance, flame resistance, voltage, conductive properties.

Q:Hydraulic hose joint dimensions

Metric plain thread1. metric screw thread with a capital M, tooth type angle 2 degrees =60 (alpha tooth type half angle);2. metric ordinary thread by pitch, coarse teeth, ordinary thread and fine teeth, two kinds of ordinary thread;2.1. coarse tooth ordinary thread mark generally does not indicate the pitch, such as M20 means coarse thread; fine tooth thread mark must indicate the pitch, such as M30 * 1.5 for fine tooth thread, in which pitch is 1.5.2.2. common thread is used for the connection and fastening between the mechanical parts, and the general thread connection is mainly made of coarse thread. The thread strength of the fine tooth thread is slightly higher than that of the same nominal diameter, and the self-locking performance is better.Mark 3. metric screw thread: M20-6H, M20 * 1.5LH-6g-40, where M represents a common thread metric, 20 nominal diameter thread is 20mm, 1.5 pitch, LH said, 6G 6H left, said thread precision grade, precision grade of internal thread uppercase, lowercase precision grade of said external thread, 40 screwing length.

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.
