What is the white substance on the surface of the red tape in the industrial belt? Will it affect th

1) Improper process operation.

Uneven mixing results in poor dispersion and local excess of saturation.

The mixing temperature is too high, so that the compounding agent is locally excessive.

Inaccurate weighing (over-weighing, under-weighing, under-weighing, mis-weighing).

If the vulcanization temperature is too high, the polymer degradation will cause frosting.

If the vulcanization temperature is too low, the under-sulfur spraying will occur due to incomplete reaction.

The vulcanization time is not enough, resulting in under-sulfur spraying.

Improper operation of sprayed release agent or mold washing water causes whitish on the rubber surface.

2) Fluctuations in the quality of raw materials.

Due to the different materials, different manufacturing methods, different processes, and different batches of raw materials, the synthesis process of raw rubber: polymerization temperature, catalyst, synthetic monomer, etc., cause different solubility. Purity, moisture, ash, pH, physical properties, etc. change.

3) Poor storage conditions.

Temperature: The solubility of compounding agent in rubber generally rises and falls with the rise and fall of temperature.

Time (pressure and humidity): The pressure of rubber storage, the humidity of the surrounding air, and time also have an impact on the solubility of the compounding agent, but generally have little effect [6]. However, if the pressure is large, the compounding agent in the rubber at the pressure part will form crystal nuclei, which will be precipitated from the rubber surface and form frosting; If the humidity of the air is too large, the effect of the polar compounding agent in the rubber on the raw rubber (non-polar) is weakened, and the solubility of the compounding agent decreases, which leads to frosting; The longer the storage time, the more obvious the frosting on the rubber surface, because the temperature and humidity of the air in the storage environment are different with the change of the season, and the difference is large, it is easy to cause the solubility of the compounding agent to change, resulting in frosting.

4) Rubber aging.

The aging of rubber mostly leads to the destruction of the complete and balanced network structure of vulcanized rubber, which also destroys the chemical or physical combination between various compounding agents and raw rubber molecules and compounding agents in the rubber system, and reduces the solubility of the compounding agent in the rubber system. As a result, compounding agents that are locally supersaturated will be free-precipitated from the rubber to form frosting.

In fact, this white substance will appear in the belt, which means that the belt is still continuing to vulcanize. This has no effect on the belt.

This problem is relatively general because there are many industrial belts, such as V-belts, synchronous belts, wide-angle belts, multi-groove belts, flat belts, variable speed belts, precision synchronous belts, reinforced synchronous belts, different series of belts According to his material, width, length have corresponding precautions, synchronous belts need to pay attention to the storage environment, not in a humid environment, can not be stored in a burst environment, otherwise it will affect the life of the belt.

My suggestion is:

Belts and pulleys should be kept clean and free of oil and water.

2.When the belt is installed, the transmission system should be checked, whether the transmission shaft is perpendicular to the transmission wheel, whether the transmission shaft is parallel to each other, whether the transmission wheel is on a plane, if not, it should be corrected.

3.Do not attach grease or other chemicals to the belt.

4.When the belt is installed, tools or external forces should not be applied directly to the belt.

5.The temperature range of the belt is: -40°-120°C.

6.During storage, it should be avoided to deform the belt due to excessive weight, prevent mechanical damage, and should not be bent and squeezed excessively.

7.During storage and transportation, it should be avoided from direct sunlight or rain and snow, kept clean, and prevented from contact with substances that affect the quality of rubber, such as acids, alkalis, oils and organic solvents.

8.During storage, the temperature of the warehouse should be kept between -15 and 40 degrees Celsius, and the relative humidity should be kept between 50% and 80%.

Due to the differences in the performance and materials of each brand of industrial belts, there are still some differences in the storage method of each industrial belt, but they are the same, and I hope it will be helpful to you.

When the human body is injured, a lot of white blood cells will gather at the wound to kill the bacteria that try to enter the body, and the white blood cells work in the same way, and they will remain in the wound after the work is over, so they will leave a white substance.

There are three categories of industrial belts: industrial transmission belts, automotive transmission belts and conveyor belts. The first two belong to transmission belts. Transmission belts are used to transmit mechanical power, including flat transmission belts and triangle transmission belts (V-belts).

It is constructed of rubber and reinforcing materials such as cotton canvas, rayon, synthetic fibers or steel wire. It is made of multi-layer rubber canvas, synthetic fiber fabric, cord and steel wire as the tensile layer, and then molded and vulcanized after being laminated with rubber. Compared with gear transmission and chain transmission, belt transmission has the advantages of simple mechanism, low noise and low equipment cost, and is widely used in various power transmissions.

The annular belt driven on the machine is sleeved on two pulleys, mostly made of cowhide or thread rubber, commonly known as belt.

The transmission belt is the power generated by the rotation of the motor or engine of the prime mover, which is transmitted to the mechanical equipment by the belt through the belt wheel, so it is also called the power belt. It is the core connecting component of electromechanical equipment, and it is extremely versatile and versatile. From giant motors ranging from thousands of kilowatts to micro motors of less than one kilowatt, and even precision machinery such as home appliances, computers, and robots, transmission belts are inseparable.

Its biggest feature is that it can be changed freely, far and near transmission, simple structure and easy to replace. Therefore, from the original machinery to modern automatic equipment, there are transmission belts, and the products have undergone many evolutions, and the technology has become more and more mature.

Transmission belts can be divided into V-belts, synchronous belts (toothed belts, timing belts), flat belts (sheet base belts, dragon belts), agricultural machinery belts, high-speed oil-proof belts, round belts (round belts), flat belts, water tower belts (wide-angle belts), transmission belts, motorcycle transmission belts, V-belts (V-belts), parallel belts, multi-groove belts, hexagonal belts, active belts, traction belts, and automobile belts.

Conveyor belts are widely used in cement, coking, metallurgy, chemical industry, steel and other industries with short conveying distance and small conveying volume. The conveyor belt is made of multi-layer hanging rubber wool canvas as the skeleton, and the surface is covered with rubber materials with good performance, which is made by vulcanization. All conveyor belts must be connected into a ring before they can be used, so the quality of the conveyor belt splice directly affects the service life of the conveyor belt and whether the conveyor line can run smoothly and smoothly.

Generally, the common methods of conveyor belt joints include mechanical joints, cold bonded joints, hot vulcanized joints, etc.

Conveyor belts with ordinary cotton canvas conveyor belts, nylon (NN) conveyor belts, polyester (EP) conveyor belts, large inclination (corrugated flange) conveyor belts, skirt partition conveyor belts, ring conveyor belts, pattern conveyor belts, waterstop belts, PVC or PVG whole core flame retardant belts and various special performance conveyor belts (general flame retardant conveyor belts, heat-resistant conveyor belts, burn-resistant conveyor belts, high wear-resistant conveyor belts, acid-resistant conveyor belts, alkali-resistant conveyor belts, cold-resistant conveyor belts, oil-resistant conveyor belts, high-temperature resistant conveyor belts, High Strength Conveyor Belts and Food Conveyor Belts). According to the tensile strength of the conveyor belt layer, it is divided into ordinary conveyor belt and strong conveyor belt. Powerful canvas conveyor belts are divided into nylon conveyor belts (NN conveyor belts) and polyester conveyor belts (EP conveyor belts).

Conveyor belt splice technical tips.

Upstairs, it's basically the same material, functional.

Timing belts.

The V-shaped pulley transmission can alleviate the load impact, the pulley transmission runs smoothly, low noise and vibration, and the structure of the pulley transmission is simple and easy to adjust. The manufacturing and installation accuracy of the pulley drive is not as strict as that of the meshing drive.

The groove of the pulley is actually designed according to the belt, and there are many types of industrial belts, such as the common U-shaped, V-shaped, tooth-shaped, etc., and the corresponding pulleys are U-shaped pulleys, V-shaped pulleys, and toothed pulleys. Among them, V-shaped pulleys are generally used in large industrial motors, and toothed pulleys are generally synchronous pulleys.

The V-belt, or V-shaped belt, is a unique conveyor belt, which is a mechanical equipment used to transmit force and transport goods. It is easy to install, small in footprint, high in transmission efficiency and low in noise. V-shaped tape is referred to as V-belt or V-belt, which is a general term for the annular transmission belt with a trapezoidal cross-section, which is divided into two categories: special core V-belt and ordinary V-belt.

According to its cross-sectional shape and size, it can be divided into ordinary V-belt, narrow V-belt, wide V-belt and ribbed belt, according to the belt structure, it can be divided into cloth type V-belt and trimming V-belt, and according to the core structure, it can be divided into cord core V-belt and rope core V-belt. It is mainly used in the power transmission of mechanical equipment driven by electric motors and internal combustion engines. The V-belt is a type of transmission belt.

Industrial V-belts are equipped with ordinary V-belts, narrow V-belts and combined V-belts.

V-belt, scientific name V-belt, triangle belt special core structure and rope core structure, respectively composed of four parts: cloth, top rubber, tensile body and bottom rubber. The V-belt of the rope core structure is easy to manufacture, the tensile strength is general, the first is cheap, and the V-belt with the core structure is widely used, with good toughness and high strength, and is suitable for occasions with high speed.

There are two types of triangle belts: special core structure and rope core structure. The rope core, also known as the ordinary belt core, is twisted or braided from fibers. The special belt core is composed of polyester tempered brown silk, with good adhesion, flexural resistance, high strength, no stretching, and its service life is 5-10 times that of the rope core structure triangle belt.

As a means of power transmission, it is the most common belt, which is easy to buy economically** and easy to replace.

The belts are free to be hung up for multiple belts.

The red V-belt is a belt with strong heat resistance, oil resistance, bending resistance, and static resistance for high-load transmission.

The cross-section is V-shaped. It is used in applications where high friction is required.

Hee-hee, after a long time, you'll know.

T10-530 is a timing belt, but this is not a complete model, it should also have a width For example: T10-530-10

SPB8000 is a high-speed oil-proof narrow belt, and it is also a kind of V-belt, and the non-toothed belt should be distinguished from the XPB8000, and the XPB8000 is a toothed high-speed oil-proof V-belt.

Generally, the brand can not be judged from the model, and the imported and domestic V-belts need to be converted!

Automatic conveying equipment factories will be useful,

V-belts are widely used in agricultural machinery. The standardized V-belt has a trapezoidal cross-section, and there is no joint in the whole circle, which is divided into seven types: O-shaped, A-shaped, B-shaped, C-shaped, D-shaped, E-shaped, and F-shaped, and the profile area of the belt gradually increases from O-shape to F-shaped, and the choice of tape model is determined according to the speed of the power belt transmitted, which has a lot of knowledge.

Standard model The selected model should be abnormal with the selected triangle tape in the pulley groove, when replacing the triangle tape, it is best to bring the old to the agricultural machinery department to buy, in case the model is wrong.

Correct installation Before installation, if the center distance of the two axes is adjustable, the center distance should be shortened first, and then the center distance should be adjusted according to the requirements after the tape is installed, if the center distance of the two axes is not adjustable, a V-belt can be put into the wheel groove first, and then turn another pulley, the V-belt is loaded, and a group of V-belts are loaded in the same way. During installation, it is forbidden to pry with tools and pull on the V-belt to prevent the V-belt from being elongated or too loose or tight.

Prevent the slot When installing the pulley, the center of the pulley must be aligned, otherwise it will cause the Unilateral work of the V-belt, which will cause serious wear and tear, and affect the service life of the V-belt.

Suitable tightness The V-belt is too loose not only to slip, but also to increase the wear of the V-belt, and even unable to transmit power; If it is too tight, it will not only elongate and deform the V-belt and be easily damaged, but also cause the main bearing and clutch bearing of the engine to be over-stressed, which will accelerate the wear of the V-belt. The correct inspection method is: apply a vertical pressure of about 2 kg in the middle of each tape by hand, and the sinking amount is 20-30 mm.

When the old and new mixed double or three or more triangle tapes need to be replaced, the specified type of triangle tape should be selected, and the tightness of each group of triangle tapes is required to be consistent, and the old and new triangles are not allowed to be mixed or the number of uses is reduced, otherwise, the new and old triangle belts are unevenly stressed, and even the old triangle belts cannot be used for fighting, which affects the power transmission and shortens the life of the triangle belts.

Strictly prevent pollution During use, it is necessary to strictly prevent the V-belt from being stained with oil and mud, and avoid contact with corrosive substances such as acid and alkali to prevent early damage from slipping and corroding the V-belt.

Daily maintenance The operator and the user should master the correct operation essentials in the usual driving of agricultural machinery, and try to avoid sharp start and sudden braking in accordance with the technical requirements of the instruction manual, and should also prevent frequent overload operation. If the machine is out of use for a long time, the triangle tape should be removed and stored separately.
