What are the characteristics of concrete laser leveling machine?

When the concrete laser leveling machine fails, it needs to be repaired. Generally speaking, maintenance is a good way to help the leveling machine to restore health, but some leveling machines still have a lot of small problems after maintenance. What is this ? In fact, because some maintenance personnel in the maintenance of concrete laser leveling machine, the error caused by the error, the following error in the maintenance of concrete laser leveling machine when do not make it again.

    The "compatibility" between a topping spreader and your base concrete is essentially a question of surface energy and structural bond. If the base concrete is too rough, too smooth, or too "dead" (hardened), your spreader-regardless of how expensive or precise it is-will fail to distribute the topping properly. Here is how to match your spreader setup to the surface texture of the base slab. The Texture: A fresh, laser-Levelinged surface is smooth but "open," meaning it still has plenty of exposed paste and moisture. Compatibility: This is the "Goldilocks" zone for spreaders. Spreader Adjustment: You can use high-speed rotary spreaders (the ones that throw material using centrifugal force). Because the surface is open, the topping will immediately "drink" the bleed water and bond instantly. Best Practice: Do not wait too long. If the slab surface begins to "crust" (harden), the topping will just sit on top, leading to delamination later. The Texture: A slab that has already been power-floated once is "closed"-the pores are sealed. Compatibility: This is difficult for standard spreaders. The Challenge: If you try to spread dry-shake on a closed surface, it won't hydrate. The powder will act like a "slip layer" (like ball bearings), causing your finishing machines to slide around, or worse, the topping will never bond. Spreader Adjustment: Use a gravity-drop spreader (not a rotary thrower). You need a very precise, uniform layer. You must also follow the spreader with a trowel-based re-opening pass to break the surface tension and force the topping into the slab. The Texture: Often seen in exterior slabs or ramps. Compatibility: Highly incompatible with standard dry-shake spreaders. The Problem: The peaks of the broom finish will strip the topping off the spreader, causing "streaking" or "clumping." Spreader Adjustment: If you must apply topping to a rough surface, you cannot use a mechanical spreader effectively. You are better off using manual broadcasting techniques or a high-pressure pneumatic blower that can "blast" the powder into the deep valleys of the texture. Base Surface Texture Spreader Compatibility Recommended Spreader Type Key Risk Fresh/Levelinged (Open) Excellent Rotary Spreader Over-spreading (waste) Smooth/Power-Floated Moderate Gravity-Drop Spreader Delamination (lack of bond) Broom/Rough Finish Poor Manual/Pneumatic Only Uneven coverage/streaking Cured/Hardened Incompatible N/A Total failure (no bond) The compatibility isn't just about the physical texture; it's about bleed water. * If your surface texture is "open," it has high moisture availability. You need a fast spreader speed to keep up with the hydration. If your surface texture is "closed," it has low moisture availability. You must reduce the spreader speed and immediately follow with a mechanical disc-trowel to "work" the topping into the slab. If you are spreading on a base that is still very soft (wet), your spreader must use flotation tires or wide tracks. If the spreader sinks into the texture (ruts), it creates physical troughs. The material will naturally accumulate in these troughs, creating a non-uniform floor. Compatibility Fix: Always ensure the spreader is calibrated for the weight-bearing capacity of the specific mix design you are using. A good rule of thumb: The amplitude of your surface texture must be less than the particle size of your topping. If you have a coarse broom finish (deep valleys) and you use a fine-powder pigment, the pigment will vanish into the valleys and won't be visible on the peaks. In this case, you need a larger aggregate size in your topping mix to "bridge" the texture.

The laser leveling machine plays a vital role as the main equipment for floor construction. When the summer comes, the floor construction will gradually enter the peak season, and it is very important to ensure the working condition of the equipment. High temperature construction in summer is also a test for concrete and concrete laser levelers. Do a good job in equipment maintenance and work to maximize the efficiency of the equipment.   Learning equipment maintenance is not only related to the construction quality of the floor, but also related to the service life of the concrete laser leveling machine and construction safety. Do a good job in machine maintenance and guarantee your investment. This issue brings you the summer maintenance micro-classroom of the YZ28-4S/ YZ28-4. These two equipments are two four-wheel drive YZ28-4S that been developmented by VANSE or many years. YZ28-4S concrete leveling machine. two devices follow the excellent quality of the Hummer model, and the product development habits and requirements of domestic customers are fully considered in the product development process. Therefore, in addition to the performance guarantees of these two new products, the customer operating experience has also been significantly improved. Precautions: * Avoiding the engine too hot.  Under normal circumstances, the temperature of the engine should not exceed 95°. If the temperature is too high, you should choose a cooler position to stop the cooling. When the machine is stopped, the hood can be ventilated and cooled. *  To detect the amount of cooling water in time.   When the water radiator reaches 100°, do not rush to add cooling water. Instead, stop the engine immediately after idling and then add coolant. *  Clean the radiator timely.   Includes coolant radiator / oil radiator / hydraulic oil radiator to prevent poor heat dissipation. * The construction temperature in summer is very hot, so it's better to check the wheels air pressure and temperature. If the temperature of the wheels too hot, . If the temperature of the tire is too high, stop it in time and place it in a cool place to cool down. Avoiding  use the wrong method of deflation or cold water to cool down. *  Maintenance-free batteries need to be checked frequently for their working conditions. The observation hole shows that green represents normal. * Prevent engine knocking .Before entering the summer, the carbon deposits in the combustion chamber, valve top and other parts should be completely removed to maintain good heat dissipation and normal compression ratio; it is necessary to check and adjust the fuel supply advance angle to prevent engine deflagration. * Always check the temperature of the hydraulic oil and hydraulic transmission oil . If the temperature is too high, stop it and stop it. Do not operate at high temperatures. * In summer, the concrete solidifies at a faster speed, so it is necessary to clean the equipment in time, otherwise it will cause damage to the machine.   If yoour machine happen somethings wrong, do not worry!
