Why does the polishing machine need to set the speed? Because when everyone uses the polishing machine, they use different turntables and grinders. Use a coarse polishing disk such as a wool disk to increase the speed to easily wear through the polished part, so the speed is generally set at 800 to 1200/min. Similarly, if a coarser abrasive is used, the speed also needs to be lowered. In other cases, in order to improve the polishing quality, it needs to be carried out in different steps. Rough polishing and fine polishing are performed. The speeds of these two stages are different. Rough polishing requires a low rotation speed of the turntable, preferably not more than 600r/min; the polishing time should be longer than the time required to remove the scratches, because the deformed layer must be removed. After rough polishing, the grinding surface is smooth, but dull and dull, and there are even and fine wear scars observed under the microscope, which need to be eliminated by fine polishing. The speed of the turntable can be appropriately increased during the fine polishing, and the polishing time is appropriate to throw away the damaged layer of the rough polishing. That's roughly the reason for the above.

How to deal with the different abrasive wear of floor grinders After the floor construction, the floor grinder needs to be maintained and repaired frequently to avoid machine failure during construction without knowing it. In addition, any problems arising from the floor grinder during floor construction must be dealt with in time, otherwise, it will affect the resulting ground effect. The difference in abrasive wear is also a problem that needs attention. Learn to judge and deal with it. Whether the abrasive wear of the machine is different can be judged from these points: ①The buffer rubber is aging or damaged; ②The grinding disc is not in the same working plane; ③The buffer spring is damaged. According to construction practice and technical experience, these two methods can be adopted to solve the problem: ①Replace the cushion rubber pad; ②Adjust the fastening bolts to keep the grinding disc on the same plane

The specific role of concrete curing After the concrete is poured before the floor construction, we need to choose the appropriate maintenance method according to the actual situation. The curing time also varies with different cements. However, how does the curing agent work? What is concrete curing? The process of ensuring the smooth progress of cement hydration in fresh concrete is called curing. Concrete curing generally refers to maintaining a certain degree of humidity. In the case of sufficient moisture curing, the cement can reach the maximum degree of hydration, but in the case of rapid drying, only a limited degree of hydration can be achieved. If the cured concrete is not good enough, the quality will not be achieved. The role of conservation Generally, the mixing water consumption of concrete must be greater than the water requirement of cement hydration. However, after the initial setting of concrete, water loss due to evaporation or other reasons will affect the full hydration of the cement. Especially on the surface layer of concrete, when the concrete dries to a relative humidity below 80%, the hydration of the cement tends to stop, which damages the various properties of the concrete. The surface concrete is very important to the durability, abrasion resistance and appearance of the concrete structure, so the maintenance of the surface concrete is very important. The loss of surface moisture not only affects the surface layer of the concrete, but also because the moisture inside the concrete exists in the capillaries, the moisture will rise or fall along the capillaries. When the surface moisture is insufficient, the moisture in the capillaries will continue to rise to the concrete. On the surface, the moisture will evaporate further and will gradually affect the insufficient moisture inside the concrete. Therefore, during the curing of concrete, it is necessary to ensure that the surface of the concrete has sufficient humidity, and at the same time, the evaporation of water must be prevented. Generally, the concrete must be kept wet after pouring. The curing time varies from cement to cement, and generally takes 7-14 days. If conditions permit, you can take cover wet cover, you can also sprinkle cover. For structures that do not have conditions to cover wet curing and water spray curing, concrete curing agent can be sprayed on the concrete surface for curing. For example, some complex parts of structures, water-deficient areas and so on. The curing agent curing method can effectively prevent the concrete moisture from evaporating, keep the internal moisture of the concrete, and enable the hydration to proceed fully.

Little knowledge about industrial vacuum cleaners（2） What can be done to extend the service life of industrial vacuum cleaners? If you want to extend the service life, you need to pay more attention to the maintenance of industrial vacuum cleaners. 1. Before use, first check whether the garbage in the vacuum cleaner is cleaned, and then check whether the plug and socket are clean and free of foreign matter. The last thing is to check whether the machine is normal, and then you can start using it. 2. In use, of course, maintenance is also required during use. Industrial vacuum cleaners want to extend the service life, and you must pay more attention to the usual bit by bit, so you must not allow the machine to be transported alone when using it. It must be supervised by someone, and then it is not possible to keep the industrial vacuum cleaner running for a long time, because the power of the industrial vacuum cleaner is very large, if it is operated for a long time without stopping, it is easy to cause damage, so if the machine is found to be damaged If it is hot, you need to stop and stick to it. Finally, you need to pay attention when using it. Do not let the industrial vacuum cleaner clean up corrosive garbage or glass and other sharp garbage, which will easily cause damage to the industrial vacuum cleaner. 3. After use, the industrial vacuum cleaner needs to be cleaned after use. At the same time, when wiping the industrial vacuum cleaner, it must not be cleaned with corrosive cleaning agents. At the same time, the body must be wiped clean after cleaning. Come down. Therefore, in fact, industrial vacuum cleaners need to be maintained before, during, or after use. Industrial vacuum cleaners can extend their service life only when they are maintained in the usual spot.

Little knowledge about industrial vacuum cleaners（1） With the advancement and development of science and technology, industrial vacuum cleaners have become indispensable equipment in factories. After long-term use, we will find that the suction power of industrial vacuum cleaners gradually decreases. So why? Insufficient suction: 1. The suction power is insufficient when opened for the first time Please check whether the links between all the components are installed properly, just reinstall the components that are not installed. If the link between the parts is not sealed, it will cause insufficient suction. 2. The suction power is found to be insufficient while in use Please check if there is any foreign matter blocking the air inlet; Please check if there is any foreign matter blocked in the hose; Please check whether the dust or water in the collection bucket is full; Please check whether the exhaust vent is blocked by foreign objects; Please check if the filter is blocked by dust； Please check whether the links between all components are falling off; Please check if the liquid level protector is blocking the air inlet of the motor compartment.
