What are the types of belt repair adhesives? How to use belt repair strips?

Belt repair adhesive is mainly cold vulcanized repair, which is convenient and fast. SK313 can be quickly bonded to scratched conveyor belts at room temperature. For the repair of belt damage and defects, this method can also be used, with rubber repair agent SK358, so that the belt defect can be filled in, and the bearing capacity of the original belt can be retained as much as possible.

What is more valuable is that this belt repair adhesive can save a lot of time. Do not delay the production in the factory.

In addition, there is another way to repair the belt, which is the hot vulcanization bonding method, which requires the use of unvulcanized core glue, unvulcanized surface adhesive, hot vulcanizing agent (this is a liquid SK823), and pressurized and heated vulcanization by vulcanizing machine equipment.

At present, in domestic industrial and mining production, the transmission belt of transported materials is divided into three types: ordinary conveyor belt, ST steel wire rope core conveyor belt and PVC PVG whole core flame retardant conveyor belt. Rubber belts and fabric belts can be bonded by cold vulcanization, which is easy to bond and ready to repair, but is not suitable for heavy-duty belts. Heavy-duty conveyor belts, such as steel wire rope core conveyor belts and PVC PVG full-core flame retardant conveyor belts, transport materials are relatively heavy, and this kind of belt needs to be hot-vulcanized bonding in order to achieve the strength of the normal tensile force and tension of the conveyor belt, and it is not recommended to use cold vulcanization for repair bonding.

There are several ways to repair strong belts: 1. Use RIT repair strip + cold adhesive for quick repair 2. Use T2 system for quick repair 3. Use rubber vulcanization repair agent for quick repair.

There are many forms of damage to the belt, such as: edge delamination, ulceration, chipping and cracking; Long-distance longitudinal tears, deep scratches, holes, large-scale wear and tear, covering rubber bulging or peeling, internal defects of joints, etc. Once the belt is damaged, we need to repair it in the shortest possible time to prevent the wound from expanding.

RIT repair strips are imported from Germany, which can easily complete the emergency repair of local scratches, breaks, long-distance longitudinal tears and other damage of the conveyor belt body under harsh material transportation conditions. After repairing, the repair surface quickly reaches the working strong liquid dissipation, which has the characteristics of simple operation, flexible and ready-to-repair.

Belt repair is mostly repaired with cold-adhesive SK313 and RIT repair strips.

Belt cold adhesive SK313 is a two-component rubber type fast cold adhesive glue, its cured adhesive layer has a series of good characteristics of rubber, excellent flexibility and flexibility, impact and vibration resistance, can achieve good dispersion effect on complex stress, excellent flexibility. Moreover, the cured adhesive layer of cold adhesive SK313 is resistant to water and oil, acid and alkali corrosion, high and low temperature resistance, and heat and oxygen aging resistance, and can maintain its good performance for a long time in a harsh working environment. At the same time, it also has the ability of quick-curing bonding, which can complete the bonding in a short time in the cold bonding of the coal conveying belt, achieve the working intensity, and restore the operation of the belt.

How to use it in the field:

Cold-adhesive SK313 is used to bond the RIT repair strip to the belt, and the RIT repair strip is used to adhere to the damaged area to prevent the wound from spreading. Apply the cold adhesive to the lower surface of the belt, wait for it to dry and apply it again, and at the same time apply the glue to the adhesive surface of the RIT repair strip, and attach the repair strip to the lower surface of the belt when it seems to be dry or not dry. Next, apply the cold adhesive to the upper surface of the belt twice and the adhesive surface of the repair strip, and when it is slightly sticky to the back of the hand, attach the RIT repair strip to the part filled with rubber repair agent, and use a compaction roller to roll it firmly.

Belt repair strips need to be used together with SA3100 cold vulcanized adhesive Bihu.

1. First polish the surface of the conveyor belt.

2. Clean it well.

3. Brush the mixed SA3100 cold adhesive, and then apply the second SA3100 mixture when it is not sticky, and then fit it when it is slightly sticky to the back of the fingers.

4. When the surface of the conveyor belt is coated with the second cold adhesive and the mixed liquid, it is also evenly brushed on the surface of the repair strip.

5. After lamination, use the compaction roller to compact the surface.

Schnees technical experts believe that the belt is broken with glue is only temporary, it is recommended to change one, unless there is a particularly good glue, but the cost of this glue may be higher than the price of the belt, Schnees specializes in the electronic industry glue. I hope it can help you, I hope to adopt, thank you!

With the continuous development of belt repair technology, the characteristics and functions of belt bonding repair glues are different, and the brands are also diverse.

Because the replacement of the whole belt is time-consuming, laborious and costly, it is recommended to use repair strips to bond the repair belt for general long-distance scratches, and the use of repair strips and glues that meet safety standards can usually be integrated with the belt after repair, and the bonding strength is completely worry-free, so what kind of glue should be used? What should I pay attention to when choosing a glue?

It is recommended to use a repair strip to bond the belt, and the repair strip can be quickly repaired by cold vulcanized adhesive SK313. The cold vulcanization bonding speed is fast, the strength is high, and it can be integrated with the belt after bonding, without reducing the performance of the belt itself.

When using the cold vulcanization bonding method, it should be noted that the adhesive surface of the repair strip should contain a semi-vulcanized CN layer, and the special cold vulcanized adhesive SK313 should be used to bond the belt with the repair strip. After the cold vulcanization adhesive is applied to the semi-vulcanized layer, the two can automatically vulcanize at room temperature, so that the reacted part is dissolved in the damaged part, and it can be used after it is completely cooled.

Can I use rubber patching agent for belt repair?Absolutely.

Rubber repair agent is a new type of belt cold vulcanization repair material, which is generally in the form of glue paste, which can be applied at any angle, and is mostly used for filling the damaged part of the belt and filling the drum overseal.

Cold vulcanized rubber repair agent is mostly used for filling belt potholes or filling and repairing belt scratches when repairing belts, and it is simple and fast to use without other repair materials.

Cold vulcanized rubber repair agent is also often used for the filling treatment of penetrating tear parts of the belt, and it needs to be operated with cold vulcanized glue and RIT belt repair strip when used, in which the rubber repair agent is used to fill the wound part out of the warehouse, the glue plays a role in bonding, and the repair strip is used for the fitting of the wound site, which effectively ensures the integrity of the belt after repair.

At present, the more commonly used cold vulcanized rubber repair agent is generally imported two-component, such as SK358 used as a curing agent. Stirring is required before use.

Here's how:

Operation 1: Use an angle grinder with tungsten steel disc to polish the damaged part of the belt, then use a cleaning agent to clean the grinding part, evenly apply the rubber repair agent after mixing and stirring on the damaged part, and use a scraper to scrape it flat, which is relatively simple, fast and easy to master.

Operation 2: Use an angle grinder with tungsten steel disc to polish the torn part of the belt, use a cleaning agent to deeply clean the grinding part, fill the rubber repair agent in the torn part and then use a compacting roller to roll it firmly. Apply cold vulcanized glue to the torn part twice, apply cold vulcanized glue to the adhesive surface of the repair strip, attach the repair strip to the torn part, and use a compaction roller to roll it firmly.

Belt repair strips are typically used with cold vulcanized glue for belt repair and on-site handling of cold vulcanized joints. Among them, the more commonly used RIT belt repair strip with semi-vulcanized layer can produce a self-vulcanization reaction with cold vulcanized glue and fuse on the belt repair surface, so as to ensure the belt bonding effect.

Here's how to use the RIT Belt Repair Strip:

Use a high-power low-speed angle grinder with tungsten steel disc to polish the damaged part of the belt to increase the roughness of the belt;

Use a cleaning brush to clean the residue on the grinding part, and then apply the cleaning agent to remove impurities and oil on the surface of the belt.

Evenly brush the mixed SK313 on the damaged part, and then brush it again after drying, so as to ensure that the coating is uniform and increase the glue wettability;

The adhesive surface of the repair strip is coated with a layer of cold vulcanized glue;

When the glue is slightly sticky to the finger quilt, attach the repair strip to the damaged part of the belt, and use the compaction roller to roll back and forth from the middle to the four sides to exhaust the excess air;

Glued on, I don't understand how to hit **.

The following aspects should be paid attention to when brushing the belt

1. The skin to be repaired and the skin to be repaired should be polished, and the polishing has a frosted feeling.

2. The glue must be applied evenly, not too much, as long as the skin is covered.

3. Be sure to wait until the glue is not sticky before you can paste it, and you can always press it tightly for more than a minute without a worker and a waiter.

4. When brushing the glue, do not stick to the sundries of sensitive friends, which will affect the bonding effect.

Commonly used things for mending belts are: grinders, cleaning agents, cold vulcanizing adhesives and curing agents.

When repairing, first polish the repair place, and then clean the grinding place with cleaning agent, wait for drying, mix the cold vulcanization adhesive and the curing agent in a certain proportion, and then use a brush to dip the mixture. When pasting, aim at the grinding place, wait for it to dry, and then use an angle grinder to smooth out the surrounding area.

Repair of the conveyor belt: one you have to prepare glue it! It is recommended to use Dipter's 9800 adhesive, mix the adhesive with the curing agent, then polish the repair strip and the conveyor belt, then brush the surface with a brush, then apply glue, and finally empty the air inside the pants to make them bond stronger.

The traditional belt joint bonding method is made by hot vulcanized glue, and the hot vulcanized joint needs to use RIT hot vulcanized core adhesive, RIT hot vulcanized surface adhesive and hot vulcanized glue.

The core glue is laid on the core layer of the belt, such as the fabric layer of the layered belt and the wire rope core of the steel wire belt, so as to achieve the role of filling and bonding, and the core layer is well bonded and grasped, so as to avoid the core pulling of the steel wire and the stripping of the fabric, so that the part of the belt that should be stressed plays its own role.

Top-adhesive, also known as cover-rubber, can be divided into upper cover-rubber and lower-cover rubber on the surface of the belt, which has high tensile wear resistance and plays a role in protecting and improving the strength of the joint.

Hot vulcanized glue can also be called hot vulcanized glue, such as common layered hot vulcanized glue SK813, steel wire hot vulcanized glue SK823, etc. The hot vulcanized mortar has good fluidity and viscosity, and can penetrate into the gap between the core layer of the belt and the rubber material after brushing, eliminating the bubbles inside the joint, so that the internal structure of the joint is tight and the bonding strength is improved after the vulcanization machine is heated and pressurized and vulcanized.

Belt bonding is carried out by hot vulcanization, which can reach 90% of the strength of the original belt and meet the requirements of any strength belt, especially in steel wire belts and medium and high strength layered belt joints, hot vulcanization must be used to ensure the use effect.

The development time of cold-bonded joints is relatively short, because with the development of the adhesive industry, glues suitable for bonding between rubber conveyor belts have been gradually developed, and cold-bonded repairs and cold-bonded joints have been popularized and applied.

At present, the widely used cold bonding method is called cold vulcanization bonding.

Cold vulcanization bonding requires products such as cold vulcanized adhesives, RIT repair strips with a semi-vulcanized layer, etc.

The RIT repair strip with semi-vulcanized layer can protect the core layer of the damaged part of the belt, and restore the structural strength of the belt to a certain extent, and is used to paste on the gap at the joint lap when the cold adhesive belt joint, and the repair strip can avoid the joint being scratched by the cleaner, so as to achieve the purpose of protecting and prolonging the service life of the belt joint. The semi-vulcanized layer on the back of the RIT repair strip can be quickly vulcanized with the cold vulcanized glue SK313 at room temperature, which further improves the adhesive strength of the glue.

However, the cold bonding of belt joints is only suitable for medium and low strength layered belts and canvas belts, and steel wire belts and PVC PVG full-core flame retardant conveyor belts must be hot vulcanized.
