What effect will improper adjustment of the power trowel blade angle have on the concrete surface?

  The liquid crystal surface on the body of the small laser leveler also needs to be cleaned. You can use organic resin or special cleaning cloth for lenses to wipe the dirt. If there is too much dirt, you can use lens cleaning fluid to remove it. The small laser leveler is a device that uses laser as the reference plane, adopts an original imported receiving and transmitting system, and controls the leveling head in real time to achieve high-precision and rapid leveling of concrete. I believe that friends in the industry circle have a certain understanding of the small laser leveler, so how to maintain the small laser leveler after normal use? The manufacturer of the small laser leveler will explain to you the best way to maintain the small laser leveler after use. 1. The liquid crystal surface on the body of the small laser leveler also needs to be cleaned. You can use organic resin or special cleaning cloth for lenses to wipe the dirt. If there is too much dirt, you can use lens cleaning fluid to remove it. 2. There will be a lot of dust and mud on the small laser leveler after construction. First, wipe the dust off the small laser leveler, and wipe the dirt and oil stains with thin paper or cotton cloth. 3. If the laser signal is lost during the construction of the small laser leveling machine, the machine needs to be restarted, and the interval time needs to be more than ten seconds. 4. If there are too many stains, you can soak a soft cloth in water diluted with a neutral detergent, wring it out and wash it. The small laser leveling machine manufacturer reminds everyone not to use volatile oil, thinner, gasoline and other chemicals for cleaning and wiping. 1. Preparation work ①. After the base layer is processed, the small laser leveling machine is debugged, and a fixed reference leveling point is made according to the original leveling point; non-woven fabrics are laid, side molds are supported, and laser transmitters are set up. According to the original leveling point, the ground elevation is introduced into the small laser leveling machine. Small laser leveling machine manufacturer ②. Concrete transportation Commercial concrete is used. The tank truck transports the commercial concrete to the garage entrance and exit, and then it is transported to the construction site with a three-wheel dump truck. ③. Check the elevation of the floor using a handheld laser receiver, introduce the elevation into the small laser leveler, and adjust the reference point on the leveler (±0.00). 2. Concrete pouring Pouring steps: ①. After the formwork is supported, clean the warehouse one day in advance before pouring concrete, rinse and soak with water. When pouring is approaching, drain the open water and sweep the cement slurry or interface agent. At this time, it is strictly forbidden to have obvious water accumulation. If there is, it must be removed resolutely before paving concrete. Small laser leveling machine manufacturer ②. After the concrete is put down, it is initially flattened. The flattening height should be 3 cm higher than the elevation. Then use a small laser leveler to level it. For the corners that cannot be leveled, you can use a gasoline leveling ruler or manually scrape it flat. ③. When pouring the warehouse near the wall, wait until the leveler passes by, and then use a scraper to scrape it flat in time. And so on. ④. For areas where concrete mixer trucks cannot be driven to the site, tractors are also used to transport concrete. After pouring, wait for the concrete to initially set before starting the floor finishing construction. 3. Receiver signal adjustment during construction The laser signal (frequency of 10 times/second) received by the small and medium-sized laser leveling machine receiver automatically adjusts the elevation in real time to ensure that the construction elevation is always within the set standard. Because the laser transmitter is fixed after setting, it can ensure that there is no cumulative error in the construction of large areas of ground. During construction, the operator uses a handheld laser receiver to detect the ground after the machine construction, and once again ensures that the flatness error is within the controllable range.
