Ergonomic design of ride-on concrete laser leveling machine

    In epoxy flooring construction, power trowels are primarily used for smoothing and leveling the concrete substrate. It is crucial to note that the requirements for the substrate in epoxy flooring differ significantly from those for ordinary hardened floors. While ordinary floors strive for a "shinier, better" finish, improper substrate preparation for epoxy flooring (such as excessive burnishing) can lead to delamination and peeling later on. The following are key precautions for using power trowels in epoxy floor substrate preparation: This is the most important point. Problem: High-speed power trowels at large blade angles can create a "singeing" or "smoothing" effect, forming an extremely dense, hard, and smooth metallic sheen layer (sealing layer) on the concrete surface. Consequence: This dense film seals the concrete's pores, preventing epoxy primer from penetrating and resulting in extremely poor adhesion. The flooring is prone to peeling off in large sections later on, almost like "peeling off" the skin. Consequence: This dense film seals the concrete's pores, preventing epoxy primer from penetrating and resulting in extremely poor adhesion. The flooring is prone to peeling off in large sections later on, almost like "peeling off" the skin. Recommendation: Only perform moderate polishing. Ensure a smooth surface, but maintain some microporous structure (presenting a matte or slightly textured finish). During the use of a power trowel, workers may spray curing agents to prevent excessive moisture evaporation. Note: Most oil-based or silicone-based curing agents are incompatible with epoxy resin. If curing is necessary, please use a water spraying method, or confirm that the curing agent is "removable" or "epoxy-compatible." Epoxy flooring is typically thin (1mm – 5mm), and it cannot conceal unevenness in the subfloor like a cement leveling layer. Procedure: Initial leveling must be performed using **float pans** to eliminate waviness during paving. Standard: For precision epoxy flooring, the smoothness error within a 2-meter straightedge range should be ≤ 2mm – 3mm. If the surface is not leveled during the troweling stage, expensive epoxy mortar will be required for later leveling. Blade Angle: Maintain a small blade angle. A larger angle results in more concentrated pressure, making it easier to create an overly dense finish. Intervention Timing: Finish the finishing process slightly earlier than for regular floor finishing. Stop the machine as soon as the surface is smooth and there are no obvious blade marks. Edge Treatment: Corners and column edges that the power trowel cannot reach must be smoothed by hand with a trowel; otherwise, these protrusions will be difficult to remove with a sander later. Even with a perfect trowel finish, surface preparation using a grinder or shot blaster is essential before applying the epoxy primer. Purpose: To thoroughly remove the laitance layer created by the trowel, exposing the internal sand-grain structure (similar to the texture of coarse sandpaper), achieving CSP 2-3 (concrete surface roughness grade) standards. If you are working as a base coat for epoxy flooring, the goal of using a power trowel is to achieve a **smooth, not glossy** finish.   Is your current work environment an indoor factory or an outdoor parking lot? Different environments have different requirements for the moisture content and strength (C25/C30) of the base coat. I can provide you with more detailed advice.   Note: The parameters provided in this document are for reference only and are not mandatory. Due to differences in technical characteristics between different brands and models of laser levelers, please consult the manufacturer for a suitable solution before actual operation. This reference document assumes no responsibility for any issues arising from failure to follow the manufacturer's instructions.    

The correct use of laser leveling machine manufacturer analysis skills, with the vigorous development of the construction industry, road construction is more and more frequent, which highlights the important role of laser leveling machine. Leveling machine relies on hydraulic drive leveling head, with laser system and computer control system in automatic leveling at the same time to complete leveling work. Through this article we have a brief understanding of its use of techniques.   Traditional artificial pavement leveling technology has gradually faded out of people's vision. In this era of rapid development, pavement leveling machine has brought development prospects for road construction. Through man-machine cooperation, pavement leveling technology has reached a high level.   Manual coordination: When the leveling machine is in construction, the concrete sent to the platform needs workers to open and roughly flatten as soon as possible. In addition, the area around the template, wall, column, trench, equipment foundation, floor drain or pipeline and other equipment can not be levelled, need manual coordination for local leveling. Generally, 3-4 workers are needed to cooperate with the construction.   In the use of leveling machine, of course, it is necessary to have certain computer operation technology, but also have certain tips, after all, the full intelligent robot leveling machine has not come out, for you to explain the use of leveling machine tips. In order to ensure the level of the floor, the concrete delivered to the platform must have the same slump each time. Ensure that the concrete feed rate is 40 cubic meters per hour or above and the initial setting time of each batch of concrete must be the same. Ensure that the template elevation is accurate and not disturbed during construction. The environment matches. The newly constructed concrete floor should not be exposed to sunlight, wind, rain and other unfavorable environment for the health of concrete. In addition, the laser leveling machine construction at the same time, the site can not have welding machine operation, can not have reflective objects. The foundation must reach a certain hardness to ensure that the laser leveling machine does not collapse when working on the ground. The ground height points in the workshop must be evenly distributed, and there should be no error in levelness.
