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:Three yuan ethylene propylene rubber tube covered with nylon PA66, what glue can not afford the layer?
Rubber and nylon 66 composite needs special treatment, high temperature vulcanization will not rise layer, we can wait for production, need to produce details, Baidu search: rubber technology, Li Yuan studio.
Q:Do I need a shim for the flat metal hose joint?
If the two connections are flat, they must be placed gaskets, usually with PTFE gasket.
Q:What is a rubber core pulling method?
For short component hole, a hose can be used to bend through two parallel holes; if it is used for retaining hole of long component, the two hoses of anchor can be connected by iron sheet sleeve. The length of the bushing should be 400 - 500mm, and the inside diameter should be 2 - 3mm larger than the outer diameter of the hose. The fixed position of steel derrick hose available, spaced not more than 0.5m, and fasten with steel skeleton.
Q:Why are the lengths of the household combustion equipment linked to the gas pipe hose no more than 2 meters?
A pipe is a weak link. Many accidents occur on pipes. In theory, the leakage of pipe per unit length may be the same. Then, the longer the pipe, the higher the risk coefficient.In reality, the longer the tube, the higher the possibility of being clipped. For example, bending, stretching, foot work, cracking, aging, these are potentially dangerous.
Q:Production process and raw material of rubber
The relationship between tensile strength and rubber structure: a large force between molecules, such as polar and rigid groups; the molecular weight increases, increasing the fan Edward force, the chain segment is not easy to slip, the equivalent of molecules formed between physical crosslinking points with the molecular weight increased, the tensile strength increased to a certain extent reached equilibrium; microstructure the molecular structure, such as the effect of cis - and trans structure;
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:The rubber is sheathed on a metal cylinder. How should they be connected?
If you describe it, it is recommended that a soft binder such as 704 silicone gel will be used to prevent shock absorption and separation. Metal surface to rust treatment, clean can be coated adhesive, rubber cover surface is best polished, degreasing treatment effect is good!
Q:How can I connect the gas tank connection hose?
There's no best way to pull out an old pipe.Clean up all the debris,
Q:The copper joint is leaking, and the tap water hose and copper joint are leaking
Because the water has temperature, and the thermal expansion coefficient of aluminum and copper is different,The coefficient of thermal expansion is different, that is to say, the interface is always moving (heat up, cold contraction),
