What are the common pits in the construction of concrete solidified floor? In reality, not everyone is an expert in the floor industry, and everyone knows the knowledge about concrete sealing curing agents from the exchanges between peers. Many aspects may be half-understood, which may lead to some misunderstandings of knowledge, and thus affect To the progress of construction. So, what are the common misunderstandings in concrete sealing and curing floor construction? Xingyi, as an old driver in the solidification of the floor industry, will introduce to you as follows. 1. The concrete sealing curing agent can completely seal the ground and prevent seepage. (mistaken) The concrete sealing and curing agent floor does not completely seal the pores in the concrete, and there is still room to maintain a "breathable" state. This also makes the cured floor in a humid environment (such as a basement), not due to moisture Evaporation and the whole arching causes the shell to fall off. The long service life of 20-30 years is the benefit of this. 2. The more the concrete sealing curing agent is used, the better. (mistaken) In the construction of a solidified floor, the amount of curing agent is not the better. If the amount is too much, it is easy to form a crystalline layer on the surface of the floor, causing whitening and frosting, which affects the effect feedback in the later stage. 3. Regardless of the flatness of the ground, the solidified floor can be constructed to achieve an ultra-flat mirror effect. (mistaken) An important step in the preliminary process of concrete curing floor construction is the treatment of the base surface. This process requires us to clean up the original ground and find equal work. The "leveling" is intended to improve the flatness of the ground. The leveling effect has a close influence on the later ground polishing. To make a perfect super-flat mirror effect, we even need to use a laser leveling machine to obtain a higher level of flatness during the leveling process; on the contrary, when the concrete surface has a very large drop, the depth of the polishing will also be Increasingly, just relying on polishing to make the mirror surface of the concrete smooth will probably completely polish away the concrete leveling layer. Fourth, the concrete sealed and solidified floor can prevent static electricity. (mistaken) The anti-static effect of the concrete sealing and curing floor is limited, and the simple curing floor cannot meet the needs of high-level anti-static factories. A professional anti-static floor needs to be further laid with a dedicated copper foil system or painted with anti-static paint to achieve the effect of guiding static electricity.

How to maintain the floor grinder? Floor grinders are construction equipment for builders. Incorrect use and long-term maintenance without maintenance during long-term use will shorten the service life of the floor grinders. The builders hope that the machines they buy can create big profits. Then we have to start with the use and maintenance of the floor sanding machine. Daily maintenance of floor grinder: 1. Clean all parts of the machine after each use of the floor grinder, and focus on cleaning the dust on the dust cover and grinding disc. 2. Clean the water tank of the floor grinder every five days or so to avoid the clogging of the sewage filter by the sediment. 3. After each construction, check the machine for loose screws, and tighten the screws again. 4. For the floor grinder after dry grinding, there is more dust in the floor grinder. Use a cold fan to blow from the top of the inverter box from time to time until the fan is dust-free. 5. Regularly change the gear oil for the floor grinder. The new machine is generally changed every 6 months, and then every 1 year.

Why does the resin grinding pads under the grinding disc of the floor grinder fall off? 1. If the hook cloth is not sticky, the grinding disc will fall if it is not sticky. 2. The floor is uneven, and the grinding disc will fall off easily if you hit it. 3. If the cracks are too thick and the holes are too big, the teeth under the resin grinding plate will easily fall off if they are hit. 4. The chassis is uneven, some grinding pads are hit hard, and some grinding pads are hit lightly, it is easy to fly. Use HTG floor grinder, the chance of this happening will be much reduced.

How to judge whether the gear rotation of the floor grinder is good or bad? In floor construction, floor grinders are very important floor grinding equipment. After long-term use, they may encounter some failures during operation. Among them, gear rotation is a very important problem. How to judge the floor How good is the gear of the grinder? 1. Listen to the sound, the operating noise of a floor grinder with good processing accuracy can be comparable to that of a belt drive. 2. Look at the selection of materials, high-quality equipment will consider the mechanical heat dissipation performance of mechanical dry grinding, so aluminum alloy materials will be selected. 3. Look at the accuracy of the ground grinding machine's rotation and fit clearance, and test the fit clearance by turning the grinding disc by hand. 4. The durability of the floor grinder has a lot to do with the cabinet design. After determining the cabinet material, look at the weight of the mechanical grinding head.

How to choose and use grinding pads in floor treatment? Grinding pads are one of the tools in the floor refurbishment treatment. The suitable grinding pads for floor treatment of different materials are also different. Xingyi will introduce you to the factors that affect the selection of grinding pads. Flatness of the ground Manual troweling and leveling of the ground or the old ground that is loose and severely damaged. It is necessary to level or remove the loose surface layer. You need to use a high-power grinder. Choose a grinding disc with strong grinding power and suitable for leveling, such as a concrete diamond grinding disc. The hardness of the ground The concrete used in the design and construction of the concrete floor is represented by a number, which is what we usually talk about C20, C25, C30, etc. Under normal circumstances, the higher the number, the better the strength and hardness of the concrete, but due to various Due to the influence of factors, the marking of concrete and the hardness of the ground are often not corresponding. The hardness of the concrete floor is usually expressed by Mohs' hardness. The hardness of the concrete floor is usually between 3-5. On the construction site, we can use some substitutes instead of the Mohs hardness tester to understand the hardness of the floor: the hardness of the dents and the scratches that can be drawn with iron nails and keys is less than 5, otherwise The hardness is greater than 5. The quality and speed of the grinder Floor grinding machines are usually divided into small, medium and large types. Generally speaking, the larger the machine, the greater the power, and the higher the efficiency. In actual use, it is not that the larger the machine, the better. Although the grinding efficiency of oversized and overweight grinders is very high, it will often lead to excessive grinding during use. Cost of construction. Experienced workers will adjust the machine speed, moving speed, number of grinding discs and machine counterweight according to the characteristics of the machine to reduce construction costs and improve construction efficiency. Type and size of grinding pads The commonly used abrasives for floor treatment are PCD abrasive pads, metal-based abrasive pads, and resin-based abrasive pads. PCD abrasive pads are used to remove thick coatings on the floor surface, and metal-based abrasive pads are used for floor surface pretreatment and rough grinding. Resin-based grinding pads are used for rough grinding, fine grinding, fine grinding and polishing of the surface. The particle size of the abrasive disc refers to the size of the diamond particles contained in the abrasive tool. The lower the number, the larger the particle size. The above are the 4 factors that affect our choice of polishing pads. I believe everyone has already understood. Then in the future floor treatment, if you are still wondering what kind of polishing pads to choose, you c...

What are the grinding methods of floor grinders? In floor construction, different floor grinding machinery and equipment, different floor construction conditions, and different grinding processes, floor grinding machines should use different grinding operation methods, because the correct application of machine operation methods can not only improve the construction Efficiency will also improve construction standards. 1. Straight line operation mode The floor grinder using this operation mode can greatly improve work efficiency in the later polishing process of soft ground. 2. Cross-polishing operation mode Floor grinders using this operation mode can improve the flatness of the construction ground. 3. Fan-shaped swing operation mode The floor grinder using this operation mode can improve the work efficiency of drop leveling. Therefore, according to different grounds, different needs of customers, and different processes and procedures, it is appropriate to choose the corresponding operating mode for the floor grinder.
