Some parts on conveyor Questions

1 why other construction units generally do not advocate the use of sealing glue?
A: The main function of sealing glue to cure is to connect the two ends, but also to prevent the intrusion of water and other harmful media, to prevent damage to joints sweeper.

Therefore, to make the life of vulcanized joints magnet synchronous with the band, to extend the service life of belt body sealing compound must be used.
Use sealing compound to make vulcanized joints will increase costs, but also improve the glue joints of difficulty, so some construction units would not advocate the use of

sealing compound. Actually, this makes for a negative impact on the life of the belt.material handling conveyor
2 core glue can hold, and more coating layers mortar?
A: the core adhesive glue is formed dissolved in a solvent having a viscosity gum. In all the solvent evaporated, the adhesive composition the same as the core, however,

commonly used with the core adhesive glue with a solvent (such as toluene, xylene, solvent naphtha, etc.) prepared in accordance with the ratio of 1:5-1:6

From. After the core adhesive is calendered film calender, the order of its molecules are subjected to orientation, from the mechanical standpoint, is anisotropic, so along the

rolling direction tensile properties, fatigue resistance are better. The molecular arrangement of the rubber solvent is random, with each

Isotropic. The role of glue good fluidity by the solvent, the permeability of the rubber dissolved in the solvent into Gyrosigma fully between the fabric so that the rubber can

be combined together better. Therefore, the core is the role of rubber belt plies bonded together, while eliminating

Because of different thickness interlaminar stresses caused by the conveyor belt, strain differences, and to absorb part of the destructive energy, core glue in the conveyor food conveyor

belt is an indispensable part of some foreign manufacturers in order to extend the service life, often with thick cores the thickness of the adhesive.
Brush glue instead of using only the core glue, then glue joints cloth layer thickness is relatively thin, their effectiveness will be affected.
3 sliders, and found a layer of rubberized cloth are attached, and another layer of fabric is light, and why?
A: There are attached to a layer of fabric glue stick on the following reasons:
(A) poor adhesion;
(2) good adhesion, but higher strength adhesive paste.
Generally speaking, nylon tape, with the slider portion EP, the more likely to occur twice are plastic, and the thickness of plastic about the situation, and is prone cotton

canvas cloth with the adhesive layer, and the other a layer of cloth is light case. Of course, some poor adhesion

The EP tape or glue adhesion strength is good, but stick with higher EP also appear this situation.
4 Why do I feel stiff joints than other parts?
A: The conveyor belt vulcanization bonding process is actually vulcanized rubber continue crosslinking process. As the vulcanization to heat, pressure, and requires a relatively

long time, after a relatively long time after vulcanization to the vulcanized rubber hardness will increase, so will feel than joints

Other parts of the hard.
5. Deviation when Edge wear and cause side glue fabric layer delamination, how to deal with?
A: In the case of the small size of delamination can be taken with cold glue method of repair, but be sure to pay attention to make the air emptying. Of course the best way is

to be corrected when discovered belt running.
Wear rubber roller bag can handle cold glue or hot glue treatment?
A: The roller plastic bag can be worn after cold treatment at the scene, but the scene treatment ineffective. Heat-treated roller plastic bag can generally use more than 5

years, not because of unforeseen circumstances lead to roll off the plastic bag.
6 layers cloth like two conveyor belts how butt?
A: Generally not use this approach. However, in some accident occurs, the scene had an emergency need to take this approach. With this method, it is best to layer on two seams

on the most bottom one, and to put in place adequate sealing glue rubber to eliminate

Inconsistent across the thickness of the conveyor belt joints affected.
7.EP NN belt belt and what advantages and disadvantages?
Answer: (1) NN conveyor belt cotton canvas alternative products, with high strength, fatigue resistance, good benefits, but in the course of using NN conveyor belt elongation is

relatively large, easy to spread;
(2) EP NN belt belt is an upgrade, it has the advantages of nylon conveyor belt, and because in the course of elongation is relatively small and therefore suitable even more

widely. However, EP canvas and rubber adhesive properties of NN as canvas, so glued terms of security as EP conveyor belt

NN conveyor belt.
8-long conveyor belt deviation it easy?
A: The conveyor belt during operation, and sometimes there will be deviation phenomenon. In general, the problems caused by conveyor belt itself, the situation is rare

deviation, deviation belt conveyor is mainly the reason. As the conveyor roller is not parallel to the vertical stand is not,

Roll rotation is not flexible reasons, can cause belt deviation. For relatively short conveyor belt, the rotation is not flexible side roller and other factors the probability

is relatively large, the possibility of deviation conveyor there is relatively large, and long conveyor belt, the increase in the number of rollers

, Side effects of asymmetry will be reduced, thus the performance of the conveyor out of the deviation phenomenon will become less.
9. Conveyor deviation above and below are not what caused the deviation?
A: The belt upper and lower sides are mutually affected and mutually independent. In general, lower roller parallelism, and insufficient levels of the roller conveyor will cause

lower deviation. Lower deviation, while the upper side of the normal situation is basically due to poor cleaning device, Lower Roller sticky materials with

Heavy rollers are not parallel, or counterweight bracket deflection rollers are not parallel to the next due to the specific situation should be adjusted according to actual

situation. Generally speaking, the lower deviation can be corrected, you can improve the working conditions of the cleaning device, remove the roller, roller attached some

materials, adjusting

Pinto entire lower roller, lower V-shaped roller, or install the lower side aligning roller to achieve the purpose of correction.
