What are the angles of the power trowel disc and blade? 2
In the operation of concrete power trowel, the angle adjustment of the disc and blade is crucial to the finishing effect. The specific parameters are as follows
1. Power trowel disc
Angle range:Usually there is no need to adjust the angle (the disc is flat design), and the slurry lifting effect is controlled by speed and pressure. Applicable stage:After the initial setting of concrete (there is a slight indentation when pressing with fingers but it is not sticky), it is used for surface slurry lifting and preliminary leveling.
2. Power trowel blade
First finishing:The blade angle is 10°~15°, and the operation is low speed (300~400rpm), mainly to eliminate surface floating slurry and slight bumps. Second finishing:The angle is gradually increased to 25°~30°, and compacted at medium and high speed (400~600rpm) to enhance the surface density and gloss. Special needs:If an ultra-flat surface is required (such as industrial floor), the angle can be adjusted to 30°~45° during the last finishing, but it is necessary to ensure that the concrete strength is sufficient for support.
3. Adjustment principles
Degree of concrete hardening:As the initial setting time of concrete goes by, gradually increase the blade angle to avoid roughening or sanding of the surface due to overly soft concrete. Ambient temperature:In hot and dry weather, the angle needs to be appropriately reduced to reduce the cutting force of the blade on the concrete and prevent surface cracking. Surface requirements:Conventional angles can be used for ordinary pavements, and high-precision projects (such as airport runways) need to be strictly adjusted according to design parameters.
4. Common errors and solutions
Angle is too small:It is easy to leave floating slurry, resulting in insufficient surface strength, and the angle needs to be increased in time to make up for it. Angle is too large:It may scratch the hardened concrete, so the angle needs to be reduced and the finishing speed needs to be accelerated. By reasonably controlling the angle and rotation speed, the surface flatness of the concrete can be within ±2mm/3m to meet the needs of different projects.

Laser leveling machines have a wide range of applications and significant leveling effects
As the construction industry develops faster and faster, traditional concrete leveling methods and technologies can no longer meet the needs of the current industry. Laser leveling machines can use laser technology for scientific leveling, so they have gradually replaced traditional construction methods and survived in the process of development. In order to let everyone gradually deepen their understanding of laser leveling machines, it is also necessary for the majority of users to master the situation of the equipment itself. Let us understand the scope of application of the leveling machine. The first place to use the laser leveling machine is the square and relatively open places. For many squares, leveling is always required in the later stage of construction, because this will directly affect the beauty of the entire square. Another point is that for the square, the leveling machine using laser technology can complete the work faster. The first place to use the laser leveling machine is the open space inside the house. For some houses, it is often difficult to grasp whether the corners are leveled using traditional leveling machines, because there are always some dead corners when operating manually. Laser technology can solve this problem very well, so that the entire house is leveled. During concrete construction, it is usually leveled manually, and the emergence of laser leveling machines completely liberates the inconvenience of manual operation. It greatly reduces the labor cost for the construction site, and has a significant improvement in the leveling effect of concrete. Therefore, the mechanized operation of this era can have a very large impact on the construction industry. Concrete laser leveling is a scientific and reasonable design, and there is no need for manual assistance during the operation of the equipment. This is the convenience, scientificity, and technicality of the design process. Of course, the laser leveling equipment used in different construction fields is different. Due to the diversified models and sizes of laser leveling machines in the production process, they are widely used. All of this needs to improve the advantages and technical characteristics in this aspect during the leveling process, so that it can occupy an advantage in the industry and improve the brand characteristics. In the work of concrete leveling, the use of laser leveling machines is required to enable its use effect to meet various needs, and because of the performance characteristics of the equipment itself, it has an advantage and position, and has been recognized and trusted by more builders, so it has been widely promoted in construction sites across the country.

The market demand for laser paving paver equipment is huge. During the use of the concrete leveling machine, pay attention to the following items so that the machine can serve you better: Due to the high efficiency of construction, the cutting seams in the later stage must keep up. Generally, each laser paving and leveling machine is equipped with 7-8 cutting seams to meet the requirements. The speed of the laser leveling machine should not be too fast during the leveling operation. Initial leveling should be carried out before concrete leveling, and the concrete after initial leveling should be higher than the established elevation. In the early stage, plastic film should be used for maintenance, and non-woven fabric should be covered after cutting. Pay attention to avoid obstacles when installing the laser transmitter. During the construction process, due to the lateral pressure of the concrete, the steel mesh is easy to displace horizontally. Therefore, an isolation bench is placed directly on the adjacent steel mesh, and the horizontal movement of the steel mesh is effectively controlled, and the bench can be used for turnover.
