In what fields does concrete laser leveling have broad application prospects?

    The configuration of power trowel blades (commonly known as power trowel blades or power trowel discs) directly determines the final flatness, smoothness, strength and wear resistance of the concrete surface. Improper selection and use can lead to various surface defects. The following elaborates in detail on how the configuration of the power trowel machine blades affects the final surface effect of concrete. Shape: Usually wide and thick, with a relatively small number of blades (commonly 3 or 4), and the blades have a large inclination Angle (negative Angle) with the rotating plane. Main functions: Lifting slurry and leveling. Working mode Scraping effect: The larger negative Angle causes the front edge of the blade to "shovel" the concrete surface. It can effectively level the height difference between aggregates (stones), bring the wetter mortar from the lower layer to the surface, and form a "cement slurry layer". Compaction: Through rolling, the surface aggregates are pressed into the interior of the concrete, making the structure more compact. Influence on surface effect: The front side: It provides a relatively smooth base layer rich in cement slurry for subsequent fine plastering. If this step is not taken, direct fine power troweling may bring out the aggregates, resulting in a rough and uneven surface. Negative: If it is used too late (the concrete is too hard), it will loosen the surface, causing cracks or wavy patterns. If used for too long, it will carry out excessive moisture and slurry, resulting in a fragile surface. Shape: Usually thin and narrow, with a large number of blades (commonly 8 to 12), and the Angle between the blades and the rotating plane is small, even close to horizontal (positive Angle or zero Angle). Main functions: Compaction, sealing and polishing. Working mode Patting and smoothing: Numerous and narrow blades pat and smooth the surface of the cement slurry at high speed and frequency to eliminate the marks left by rough smoothing. Sealing the surface: Compact the fine particles in the cement slurry, force the air out, seal the surface capillary pores, and form a dense, pore-free hardened layer. Generating luster: When the concrete is close to final setting, the high-speed rotating precision power trowel rubbing against the surface generates heat, causing the surface of the slurry to "melt" and present a luster. Influence on surface effect: Front: Achieve a dense, smooth, wear-resistant and dust-free surface. The level of glossiness is also determined at this stage. Negative: If used too early, the blade may get stuck in the concrete, creating wavy patterns or even damaging the surface. If used too late, the surface cannot be effectively sealed, which will cause powdering and sanding on the surface. Configuration factors The influence on the surface effect of concrete Applicable scenarios and suggestions Blade Angle This is the most crucial configuration parameter. Rough scraping stage: Use a negative Angle (with the front edge of the blade facing down) to achieve the effect of scraping and lifting the slurry. Fine smoothing stage: Use a small positive Angle or zero Angle (the blade is nearly horizontal) to achieve the effect of patting and smoothing. The larger the Angle, the stronger the cutting force, but the lower the surface finish. The smaller the Angle, the better the polishing effect. Number of blades The more the quantity, the more times each rotation is tapped, and the smoother the smoothing effect will be. Coarse power trowel (3-4 pieces) : Focuses on efficiency and slurry lifting. Fine power trowel (8-12 pieces or more) : Focuses on achieving extremely high flatness and smoothness. The more pieces there are, the finer the final surface will be. Blade material Wear resistance and toughness directly affect lifespan and performance. Spring steel: The most commonly used, it has good toughness, is not easy to break, and offers high cost performance. Tungsten carbide/hard alloy: Extremely wear-resistant, used for treating super-hard concrete or renovating old floors, with an extremely long service life, but expensive. The newness or oldness of the blade Blades that are severely worn cannot function effectively. Old/worn blades: Low efficiency in slurry lifting and polishing can lead to uneven surfaces and poor smoothness. Regular inspection and replacement are necessary. New blade: It can provide the best design Angle and cutting force to ensure the polishing effect. No matter how good the blade is, if it is used wrongly, the opportunity will be wasted. The blade and operation must be switched according to the setting condition of the concrete (the person standing on it should not sink more than 3mm). Phase One: Rough power troweling (Slurry lifting and leveling Timing: After the concrete has initially set, when it sinks by about 5 to 10mm when stepped on. Configuration: Install a coarse power trowel (negative Angle). Operation: The machine runs at a relatively slow speed and mainly focuses on leveling and large-angle scraping. Press the aggregates down and lift the cement slurry up to eliminate the obvious unevenness. Phase Two: Fine Smoothing (Pressing and smoothing) Timing: After the rough plastering is completed, when the concrete further hardens and sinks by about 1-3mm when stepped on. Configuration: Replace with a fine spatula (zero degree or small positive Angle). Operation: The machine speed can be increased and the smoothing can be carried out in a cross direction. At this point, it should be clearly visible that the surface gradually becomes fine and dense, and the rough knife marks are eliminated. Phase Three: Polishing (achieving a bright finish) Timing: When the concrete is close to final setting and there is almost no subsidence when stepped on. Configuration: Continue to use the fine spatula, but you can increase the Angle to a smaller positive Angle (if the blade head is adjustable). Operation: Run at high speed and "drift light" at a small Angle to the ground. The heat generated by friction will slightly liquefy the surface slurry, creating a mirror-like luster. Surface powdering and sanding Reason: The fine power troweling was done too late, and the surface could no longer be effectively compacted and sealed. Or the number of fine power trowel blades is insufficient or the Angle is inappropriate, resulting in poor polishing effect. The surface has wavy patterns and is uneven. Reason: The rough application was done too late, and it was caused by hard scraping and pulling. Or the blade angles are inconsistent (with different degrees of wear); The machine's walking speed is uneven. Exposed aggregates, rough surface The reason is that the coarse coating was skipped or not done thoroughly, and the fine coating was started before a thick enough layer of cement slurry was formed, which brought out the aggregates. Cracks on the surface: Reason: Using a coarse power trowel when the concrete was still too soft (bleeding period) damaged the surface structure. Or the polishing was done too early, causing the blade to sink and the material to be pushed and cracked. The configuration of a power trowel blade is a systematic project that involves using the "right tool" at the "right time" in the "right way". The rough power trowel is the foundation, responsible for creating a smooth and cement-rich working surface. The fine power trowel is the key, responsible for creating a dense, smooth and wear-resistant final surface. The Angle of the blade is the soul, directly determining whether the machine is a "scraper" or a "polishing machine". The timing of construction is the lifeblood. No matter how perfect the configuration is, it cannot play its role if the window period is missed. Only by mastering the relationship among the three proficiently can consistently produce high-quality concrete surfaces.   Note: The parameters provided in this document are for reference only and are not mandatory.
