Rubber conveyor belt in use, the joint is simple degumming, once the conveyor belt joint joint degumming, will lead to the conveyor belt can not be used, in serious cases will also form the whole conveyor line paralysis and damage. The following conveyor belt manufacturers take you to understand the reasons for the degumming of rubber conveyor belt joints.
The causes of joint degumming caused by the lack of adhesion can be roughly divided into: data and construction, that is, data quality and construction technology.
1, cold vulcanized joint information
Cold glue joint is suitable for middle and lower strength of layered with quick joint operation, can use cold vulcanized adhesive SK313 large enough to achieve the bonding strength, cold vulcanized adhesive SK313 of rubber, metal, fabric, leather stick relay over Germany DIN industrial standards, with hot vulcanization, at the same level after curing rubber flexible, strong environmental tolerance, resistance to ageing, The joint has good flexure.
Cold bonding joints have high requirements on the bonding performance of the glue used. The use of general glue, either lack of adhesion, or in order to improve the adhesion, high resin content, high curing hardness of the adhesive layer, and poor flexure resistance. Moreover, the construction of cold adhesive joints also has strict requirements on the professional skills of the operators, such as the thickness of the glue coating, the judgment of the drying degree of the adhesive layer when the sub-layered coating and bonding, the control of the thickness of the adhesive layer between the fabric layers, and so on.
After Z, the cold vulcanized joint also needs to post a patch strip at the joint gap to protect and strengthen the bonding surface and prevent peeling and degumming caused by scraping.

2, hot curing joint information
The hot vulcanization joint needs to be heated and pressurized by large vulcanization equipment, and the raw film is vulcanized to become ripe rubber. Through the hot vulcanization slurry SK823, the rubber material and the conveyor belt core layer are firmly bonded together in the vulcanization process. This type of joint has been used for many years, but its joint strength and application effect are still not comparable with other joint methods, especially in the medium and high strength fabric belt, steel wire belt, whole core flame retardant belt joints can not be replaced.
Hot vulcanized joint needs hot vulcanized glue, hot vulcanized core glue and surface glue. Hot vulcanized core glue is filled between the fabric layer or the steel wire rope of the conveyor belt, which has the filling and bonding effect, good adhesion, and good flexure and flexibility after vulcanization. Hot vulcanized surface adhesive has the characteristics of tensile resistance and wear resistance, which can form a protective layer on the surface of the conveyor belt, improve the strength of the joint and extend the service life of the joint. If the quality of the two adhesives is poor and the impurity content is large, the adhesion is very simple and can not be bonded after vulcanization.
Heat vulcanized rubber paste the same bonding effect, seemingly with a core adhesive effect overlap, but good invasive mucilage itself, liquidity that mucilage can certainly combination fabric layer, steel wire rope, and eliminate the bubbles within the aperture, ensure the compactness of joint, supply with strong stick relay, is one of the hot vulcanization joint is necessary information, Some hot vulcanized joint degumming is because the hot vulcanized glue is not used or used too little, the joint degree is not enough, in the face of strong belt tension, a pull will break. The curing process of hot curing joint also needs good technology and experience. The pressure is raised synchronously in the heating process, and the heat preservation and pressure curing temperature is reached after curing. The curing time should be controlled well, not curing incomplete, nor too sulfur.

Redirection roller - as are used with conveyor belt and conveyor, the use of the product in the concrete of beautiful shape, apply more extensive, can be used in ah cesspool, wet, muddy conditions such as evil slightly, the drum is often used, so what exactly is the purpose of his, to detail below.

The function of the drum is to change the winding direction of the tape, so that the tape forms a circular closed component. The general form of his performance is: the tail roller of the conveyor, can produce 180° of direction; The tensioning roller comprising the tensioning device; Increase the roller of the belt wrapping Angle, so that the belt has a certain direction. There are also two kinds of switch to the roller and no rubber package. The steering drum, also known as the leading steering drum, is a common belt mechanical accessory. It is mainly used in changing the running direction of the conveyor belt or pressing the conveyor belt to increase it and drive the drum. It is the driving device of various mobile belt belt machines and can also be used by some fixed belt belt machines.

The driving drum is the core output of power in conveying equipment, or the transmission unit, which can be mainly used to transport the conveyor belt and materials, provide power for use, and increase the Angle between the driving drum and the conveyor belt, so as to improve the working efficiency of the driving drum.

In general is mainly used to change the running direction of conveyor belt, or enlarged its compaction conveyor belt and transmission Angle of roller, guide roller is mainly at the bottom of the belt movement, such as belt transporting direction to the left, then the redirection roller on the right side of the belt conveyor, the main structure for bearings and steel cylinder, transmission roller belt conveyor is driving wheel.
There are many functions of changing the roller. On the one hand, it can change the direction of transportation and on the other hand, it can provide work efficiency. These two points are introduced in the above article.

EP conveyor belt, also known as polyester conveyor belt, is one of the commonly used conveyor belt products. It is divided into specifications and models according to the difference of bandwidth, number of cloth layers and covering glue thickness (working face and non-working face), and EP conveyor belt products with corresponding parameters are selected according to different operating environments. In the process of selection, we can understand the characteristics of EP polyester conveyor belt, so as to make better use of the product.
1, light weight, thin belt, high strength, soft belt body. This is a big distinguishing feature of this conveyor belt. Thin conveyor belt and do not lose strength, which is also the big reason why we choose it.
2. High impact resistance and good elasticity. Because it is a stretchy material, it does less damage when it has an impact force. 3, wear resistance, corrosion resistance. This is just the characteristics of polyester, in the conveyor belt to play a huge role.
4. Carrying capacity is high. It can be used in medium and long distance fast transportation.
How should the conveyor belt be cleaned How should the conveyor belt be cleaned
Sep .26.2022
There are many kinds of conveyor belt, and there are many kinds of colors. The conveyor belt has a wide range of applications, and because the color will be liked by more users, but the conveyor belt will easily become dirty, and it needs to be cleaned frequently. Then how should the conveyor belt be cleaned more routinely?

The production workshop of the conveyor belt needs to go through a series of cleaning work before production. Some plastic paper and other things will be spread on the ground of the workshop to prevent the conveyor belt from being stained with dust or other dirty things.

But in the process of production, there is still some dust or any other waste debris. If you get it, how do you clean it up?

In general, it can be wiped clean with a wet rag. If you encounter some places that can't be wiped off, you need to use some chemicals to wipe. No melted rubber can be dissolved in benzene, can use cotton or towel dipped in benzene to wipe, must pay attention to: benzene is flammable, is also easy to volatilize, when using must pay attention to safety, do not close to the open flame.

After the conveyor belt is wiped with benzene, the conveyor belt will be clean again, very beautiful.
How to avoid the rubber surface damage of bucket elevator conveyor belt How to avoid the rubber surface damage of bucket elevator conveyor belt
Sep .26.2022
Bucket elevator conveyor belt in the process of use often appear glue surface damage, glue surface damage after the conveyor belt there is no way to use normally, and even affect the service life of the conveyor belt, how should we avoid bucket elevator conveyor belt glue surface damage?

1. Reduce the large impact on the conveyor belt

The drop design of the transportation system is relatively large, the direction of coal flow is unreasonable, there are many large pieces of material in the material, it is possible to cause impact on the conveyor belt in the process of transportation, the surface of the conveyor belt of the bucket elevator produces a lot of pits, so that the rubber surface of the conveyor belt damage.

2. Do not touch high temperature materials

When the slag and coal of the boiler room are transported by the conveyor belt, the slag and coal without cooling will melt the covering glue on the surface of the conveyor belt and aggravate the abnormal wear on the surface of the conveyor belt. The sparks generated by electric welding and gas cutting will also have an impact on the glue surface of the conveyor belt.

3 bucket elevator conveyor belt quality

In the process of making the conveyor belt, the adhesive force of the adhesive material is not enough, the process is defective or a certain process is not strict. Under the reaction force of friction force, the covering glue is gradually peeled off on the conveyor belt, and there may be tearing when it is serious.

In a word, in order to reduce the phenomenon of damage to the rubber surface of the conveyor belt of bucket elevator, special attention is needed in production and use, and the conveyor belt of good quality should be purchased when buying, and the regular manufacturer should be purchased as far as possible. In the process of use, pay attention to the use of details, to ensure the standard operation.
