What glue is used to bond the abrasive belt on the belt grinding machine

The abrasive belt on the belt grinding machine is equipped with domestic glue with BayerCuring agentBonding.

When the interface of the abrasive belt is processed, there is a professional machine to remove sand, remove cloth or paper, brush glue bonding or paste special cloth tape after brushing, and then press it. At present, there are three joint methods for abrasive belt interface, the first is stacking, which is mostly used for paper abrasive belts. The second type of flat joint, mostly used for cloth tape.

The third kind of connection is mostly used for heavy sand cloth tape to enhance tensile strength.

The abrasive belt is divided into lap joint and flat joint, lap joint is the two ends of the abrasive cloth after the machine is thinned, and then coated with the special glue for the abrasive belt, wait for the glue to dry slightly, the two ends of the abrasive cloth are glued together, the flat joint is not necessary to grind the two ends of the abrasive cloth 1cm, just coat the abrasive belt special glue at 1cm at both ends of the abrasive cloth, and then attach a thin layer of imported tape.

Precautions for the use of abrasive belts:

1. The abrasive belt should be opened with use, and should be hung (about 24 hours) before being used on the machine to restore its natural shape and adapt to the environment, but the hanging time should not be too long in the wet season and places with high humidity.

2. The appearance quality of the abrasive belt should be checked before getting on the machine. For example, whether there are defects, protrusions, traces of fracture and others on the sand surface, check whether the abrasive belt joint is smooth, whether there is an opening, whether there is an obvious protruding joint rubber block on the back of the joint, and whether the edge of the abrasive belt is broken.

3. It is recommended that the user check whether the contact wheel of the belt grinder, the graphite pad of the grinding plate and the workpiece to be processed are normal and whether there are foreign objects.

4. The positive and negative angles of the flat tape are relative to the incision angle of the abrasive belt. Taking the front of the abrasive belt (abrasive part) upwards as an example, the different angle cuts cut to the right are positive angles, and conversely, the different angles cut out of the cloth base part upwards and to the right are reversed angles.

Now they are all domestic glue with Bayer curing agent. You have to distinguish whether it is broken, or take off, if it is broken, it is deep grinding (hurt the cloth), if it is taken off, there are many reasons, whether the glue and curing agent have deteriorated, whether the curing time is enough, whether the edge is pressed well. Whether the pressure is enough.

Whether the raw sand and glue are ground off.

with hot melt adhesive.

The composition source of hot melt adhesive is composed of basic raw materials, tackifying resins, plasticizers, fillers, other additives, etc., of which the largest proportion is basic raw materials. The basic raw material determines the basic properties and usage characteristics of the hot melt adhesive.

The basic raw materials of hot melt adhesive are divided into several categories such as EVA, TPU, PA, PES, PO, etc., and the well-known names of Chinese chemistry are ethylene-vinyl acetate copolymer, thermoplastic polyurethane, polyamide, polyester, and polyolefin.

The first answer is animal glue, which is the most important binder for the early manufacture of coated abrasives and abrasive belts, which is wide, low, strong adhesion and good vibration absorption characteristics. The second is to classify according to the chemical properties of the main components of the binder, there are two kinds of inorganic binders and organic binders, and their bonding properties are very good. There is also a classification according to the characteristics of the gluing process, including thermosetting, hot melting, solution, emulsion and sub-sensitive type.

Finally, according to the bond strength, there are two categories: structural adhesive and non-structural adhesive. Different classification standards have different performances, so we must make good use of them and choose according to our needs.

Question: Hello teacher, I want to make abrasive cloth, which kind of viscose is the strongest for grinding metal?

It can be bonded with HY-T160 glue, which can be used for the bonding of cloth and metal, and it will not fall off for several years. Generally, depending on the area that needs to be processed, you can use zero abrasive cloth for a small area.

Question: Hello teacher, can you use this glue to make a shutter wheel?

Thank you, teacher, for your question.

In fact, you should tell him the truth, in this way, he will not look for half a day, and the quality, ** have an advantage, this is not an advertisement. Otherwise, he will have to work hard to buy inferior products.

Many brands of abrasive belt machines are not the same, and the quality is not the same! How to determine the quality of the belt grinding machine? It is necessary to analyze the quality problems of the belt grinding machine, which are generally as follows:

1. Vibration problem: Some abrasive belt machines are hung with abrasive belts, and after starting the machine, the machine vibrates very much, and it will "run around" if it is not fixed! Why?

The main thing is that the balance of the turning wheel is not good! The rotating wheel has rubber wheels, guide wheels, and motor pulleys, and one of the three rotating wheels has poor accuracy, poor balance, and poor machine jitter! Another reason is that the spare parts of support wheel fit clearance is too large, causes relative movement between parts, produces vibration.

In addition, the motor is not fixed well, and vibration is also generated.

2. Noise problem: The noise is mainly due to the insufficient rigidity of the base and supporting parts, and the gap between the matching parts is too large (the processing equipment of some factories is very poor and backward, coupled with poor quality awareness, the manufactured parts are very bad, and there are almost no tolerance requirements!) ), the choice of low-quality bearings, abrasive cloth belt speed is too fast, and so on.

3. Life problem: some belt sanding machines break down after a short time, for several reasons: the adjustment part is made of gray cast iron, not made of 45 carbon steel precision casting, or no heat treatment, poor bearing quality, poor lubrication, no modulation heat treatment of the spindle, or the hardness of the treatment is too low or too high (too low is easy to wear, too high is easy to break), and the quality of the motor is not good.

4. Use problem: the size of the machine and the design of the structure are very important, and the better structure and scientific size are the key to the efficiency of the polishing worker.

Due to the continuous development of belt grinding machine and other technologies, the role of belt grinding machine polishing in the metal processing industry has become irreplaceable. With state-of-the-art belt polishing equipment, metalworking tasks such as surface polishing, circular polishing, dressing polishing and grinding, radius polishing, chamfering and deburring can be successfully completed. The modular design increases the flexibility of the equipment and reduces costs.

Industrial batch processing companies place high demands on the flexibility of the equipment they use. Thanks to the modular technical concept, production costs can be reduced and storage space in the production hall can be saved. If only the components required for each machining step are added to the basic machine, the return on investment is also very high.

The center height of the product is too low;

The grinding zone of the belt polisher product is too short;

The vibration of the grinding wheel is too great;

In addition, briefly talk about some problems to pay attention to when the CNC belt grinding machine is abnormal:

When the demand of the belt polishing machine is suspended during normal processing, the magnification switch should be slowly closed to the 0 position.

In the event of an emergency, the procedure should be stopped immediately and, if necessary, the emergency stop button can be used, which is the red emergency stop switch.

When the belt polishing machine stops due to an alarm, the alarm message should be found first, and then the spindle should be moved out of the machining position immediately. Be sure to remove the alarm before resuming processing.
