Can a laser leveler be used to make a ‘three super’ floor?

    The blades of power trowel made of different materials have significant differences in wear resistance and service life, which directly affect the construction efficiency, cost and the final quality of the floor. Below, I will conduct a detailed comparative analysis of common stainless steel, alloy (usually referring to high-carbon alloy steel), and other material blades. Material type Wear resistance Service life Main advantages Main disadvantages Applicable scenarios High-carbon alloy steel Extremely high long It has extremely high hardness, is highly wear-resistant, has a long service life and is cost-effective. It has relatively low toughness and may crack when exposed to hard objects such as stones. Not rust-proof. The vast majority of ordinary cement concrete floors are the ideal choice for those who pursue efficiency and cost. Stainless steel Low to moderate short Absolutely rust-proof, corrosion-resistant and easy to clean. It has low hardness and poor wear resistance, and requires frequent replacement or grinding. In occasions with special rust prevention requirements, such as food factories, pharmaceutical factories, chemical laboratories, and humid environments. Tool steel/spring steel Medium Medium It has good toughness, is impact-resistant and not prone to chipping. Its wear resistance is not as good as that of high-carbon alloy steel and needs to be ground regularly. The ground conditions are poor and the base layer contains a lot of hard and miscellaneous stones. Tungsten carbide hard alloy Ultimate Extremely long It features extremely high hardness and wear resistance, with a service life several times that of alloy steel. It is extremely expensive, brittle and has poor impact resistance. Super-hard floors (such as aggregate wear-resistant floors, heavy-duty wear-resistant floors) and large-scale projects that pursue ultimate efficiency. Wear resistance and service life: This is currently the most widely used and best-performing material for power trowel machine blades on the market. By adding elements such as carbon, chromium and vanadium, and through special heat treatment processes (such as quenching + tempering), its surface hardness can reach above HRC 55-60. This hardness is sufficient to efficiently grind cement mortar and provide a very long service life. Advantages High hardness and high wear resistance: In normal concrete operations, it wears out slowly and has a long single service life. High cost performance: Moderate price, achieving the best balance between wear resistance and cost. Strong versatility: Suitable for over 90% of concrete floor construction. Disadvantage Not rust-proof: It needs to be kept dry; otherwise, it is prone to rust. It should be oiled for protection when idle. Brittleness: Although it has high hardness, its toughness is relatively insufficient. If there are hard objects such as stones that have not been cleaned up on the ground, the cutting edge of the blade is prone to "chipping", forming a notch and affecting the polishing effect. Wear resistance and lifespan: The core advantage of stainless steel lies in the passivation film provided by its chromium content, which endows it with excellent corrosion resistance. However, this characteristic usually comes at the expense of hardness. The hardness of common martensitic stainless steel is much lower than that of high-carbon alloy steel that has undergone special heat treatment. Therefore, its wear rate when grinding concrete is extremely fast, and its service life is significantly shorter than that of alloy blades. Advantages Absolute rust resistance: Completely resistant to water vapor and alkaline cement erosion, easy to clean and store. Hygiene: It will not contaminate the floor or products due to rust and meets the hygiene standards of specific industries. Disadvantage Poor wear resistance: This is its main shortcoming, which requires more frequent replacement or grinding, increasing downtime and blade costs. Low cost-effectiveness: Although the blade itself may not be expensive, due to its short lifespan, the overall usage cost is high. Tool steel/spring steel Greater emphasis is placed on toughness and fatigue strength. They can withstand greater bending and impact without breaking or chipping. Its wear resistance lies between that of stainless steel and high-carbon alloy steel. It is applicable to working conditions where the ground conditions are uncertain and there may be hidden hard objects. Tungsten carbide hard alloy blade The peak of wear resistance. It does not work on the steel substrate. Instead, it bonds extremely hard tungsten carbide particles together through metals such as cobalt, with a hardness of over HRA 90 (much higher than HRC). The service life is usually 5 to 10 times or even longer than that of high-carbon alloy steel. The drawback is that it is extremely expensive, usually more than ten times the price of alloy blades, and it is very brittle and highly sensitive to impact. It is usually welded to the cutting edge of ordinary alloy steel blades in the form of "wear-resistant blocks" or "hard alloy cutting heads", which not only ensures wear resistance but also controls cost and overall toughness For the vast majority of conventional concrete floor construction: High-carbon alloy steel blades are preferred. It strikes the best balance among wear resistance, lifespan and price, making it the most cost-effective choice. For special environments with strict hygiene and rust prevention requirements: Such as food processing plants, dairy factories, pharmaceutical factories, chemical plants, swimming pools, basements, etc., even if the stainless steel blades have a short lifespan, they must be used to prevent rust pollution and ensure the quality of the floor. For super wear-resistant floors with extremely poor ground conditions or containing a large amount of hard aggregates: Consider using alloy blades with tungsten carbide wear-resistant blocks. Although the initial investment is large, in the face of extreme wear environments, its extremely long service life can significantly reduce the frequency of blade replacement and downtime. From the perspective of the entire project cycle, it may be a more economical choice. How to further increase the lifespan of blades (regardless of material) : Correct operation: Start smoothing the concrete only after it has reached the appropriate initial setting period (about 3-5mm sunken when stepped on by a person). If it is done too early, the slurry will stick; if it is done too late, it will not be able to be ground smoothly, both of which will accelerate wear. Timely grinding: After use, the blade will become dull. Regularly grinding the cutting edge with an Angle grinder can restore its sharpness and effectively extend the total service life. Proper storage: After use, clean the clean water slurry, apply anti-rust oil to the alloy steel blades, and store in a dry place. Wear resistance and service life are not determined by a single "material", but are jointly determined by "material + heat treatment process". In the vast majority of cases, high-carbon alloy steel that has undergone good heat treatment is the best choice for power trowel blades. Stainless steel is irreplaceable in specific fields due to its unique anti-rust performance, but it needs to accept the disadvantage of its relatively poor wear resistance. For extreme working conditions, "king" grade tungsten carbide hard alloy blades can be considered.   Note: The parameters provided in this document are for reference only and are not mandatory.

Concrete construction is generally leveled manually, and the appearance 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 the concrete. Therefore, mechanized operations in this era can have a great impact on the construction industry. Concrete laser leveling is a scientific and reasonable design, and there is no need for manual assistance in the operation of the equipment, which is the convenience, science, technology, etc. in the design process. Of course, the laser leveling equipment used in different construction fields is different. Because the concrete laser leveling equipment has a variety of models and sizes in the production process, it has a wide range of uses. All of these need to improve the advantages and technical characteristics in this aspect during the leveling process, so as to be able to occupy an advantage in the industry and improve the brand characteristics. As in concrete laser leveling, it must be seen through the concrete construction process. This is the key to technological progress. It has full advantages and status in the field of various leveling and leveling equipment, and has been recognized and trusted by more builders, so it has been widely promoted in construction sites across the country. Issues that should be noted: (1) Due to the high construction efficiency, the later cutting must keep up. Generally, each laser leveling machine is equipped with 7-8 cutting machines to meet the requirements. (2) In the early stage, plastic film should be used for maintenance, and non-woven fabric should be covered after cutting. (3) During the construction process, due to the lateral pressure of the concrete, the steel mesh is easy to displace horizontally. For this reason, an isolation bench is placed directly on the adjacent steel mesh, so that the horizontal displacement of the steel mesh can be effectively controlled, and the bench can be used repeatedly. Advanced equipment such as laser leveling machines are especially suitable for projects such as docks, storage yards, expressways, airports, large squares, parking lots, and municipal roads that have relatively simple shapes, large amounts of action, and high construction quality requirements.       DETAIL   IMAGES
