Q:What's the difference between a rubber belt and a polyurethane belt?

The strength and elasticity of rubber are betterPolyurethane is more flexible and less prone to deformation! The weight is comparatively lightThe plant's line is good with polyurethane!If it is a mine or coal or similar mineral, use rubber as a good point

Q:What are the structural features of the sealing device of the floating roof tank?

The sealing material has great flexibility, so that it can keep the tank wall and the floating tip clearance changes (B + 80mm) good seal, also can make the floating roof lifting freely without getting stuck.

Q:How to distinguish sanlux rubber belt quality

1 the cause of the deviation of the conveyer belt is the basic reason of the deviation of the conveyer belt, which is caused by the unbalance of the transverse force during the running of the belt. The main reasons are as follows: 11 installation quality 1) rack and roller are not adjusted straight.2) the roller axis is not perpendicular to the center line of the conveyor belt.3) the frame and the ground connection strength is not enough, the frame is unstable.4) the material and the baffle of the guide trough and the discharging trough are improperly installed and the force is uneven.12 conveyor belt quality 1) conveyor belt joint and central line is not straight.2) conveyor belt with a S shape.13 load quality, loading point is not in the center of conveyor belt.14, maintenance quality, drum cleaning is not clean, sticky coal, material, drum tilt, deformation and so on.2 conveyor belt deviation treatment, conveyor belt deviation many factors, at the same time, because of the belt conveyor type is different, its correction method is not the same. The deviation phenomenon should be analyzed carefully and corresponding measures should be taken.

Q:What sectors does rubber drive? That is to say, what are the main uses of rubber?

Cars, railways, shoes, wires, cables, new materials, many

Q:How to clean rubber band?

1. Soak it in hot water for a while, then you can peel it off.2, use the hair dryer blow, the glue baking heat can be got down.3, with Fengyoujing rub, then try out.4, you can try a rubber. But in the beginning, you may think the more you rub the dirt, but the longer the rub, you will see the effect, this method is relatively tired, have perseverance.5, with blisters, put a little detergent, and then use an old toothbrush to brush.6, with a cloth with alcohol or Erguotou wipe it.

Q:The rubber strap is a little tight, is it better or a little loose?

The tightness of watches can be adjusted. Different styles of famous brand watches can be adjusted differently.

Q:Why are the engines almost all rubber belts?

All kinds of driving methods have their own advantages and disadvantages.Sprocket, chain drive - transfer speed is limited.Gear transmission --- the transmission distance is limited and the noise is great.Belt drive - smooth transmission, quiet, easy to implement, low cost.

Q:What is the function of the coal feeder? What are the common types of coal feeder?

Main features of a coal loaderFeeding a large amount of 200 ~ 4000t/h, stepless speed regulation, according to the specific conditions of continuous adjustable (manual or electric stepless speed regulation);The ring belt is a steel core net belt conveying a special model, using 16MN alloy and 45 steel, high density, abrasion resistance, impact resistance, the characteristics of strong penetration ability, good elasticity, the structure of knitting, with anti deviation, anti slip function; overcome the old pavilion with a layer of coal and easy to clip in a belt and belt out, the emergence of the phenomenon of skidding, broken belt, leading to the maintenance of high labor intensity and high cost; the belt anti deviation lining structure, the endless belt middle cast a trapezoidal rib, with anti deviation function, greatly overcome the problem of the past, the deviation of the belt.

Q:What are the advantages of natural rubber?

Major performance characteristics:Advantages: (1) with a crystalline, self reinforcing rubber is very good, with high mechanical strength and adhesive(2) has a unique viscoelastic, high molecular weight, high Mooney viscosity, generally without mastication can use(3) non-polar, soluble in nonpolar solvents, good adhesion, good elasticity, hysteresis loss, bending deformation can flex repeatedly2, shortcomings: (1) non rubber ingredients, and large fluctuations (4% ~ 10%), so the quality is not uniform, containing unsaturated double bonds, easy agingApplication: tire, adhesive tape, rail, rubber roller, adhesive tape, general sealing ring, bridge support and inside and outside tire

Q:What is the essential difference between the effect of electric tape and rubber band?

Electrical tape refers to the PVC material. Polyvinyl chloride film coated with pressure sensitive adhesive. Generally used in automobile maintenance, wire and cable terminals and intermediate joints insulation protection, acquaintance, color separation, sheath protection, wiring harness.
