Emery floor cleaning and emery wear-resistant floor maintenance Emery flooring is widely used in industrial plants, warehouses, parking lots and other places because of its wear resistance, anti-skid, and easy cleaning. However, long-term use and improper maintenance may cause stains, wear and other problems on the floor, affecting the appearance and usability. Therefore, cleaning and maintenance during operation is very important. This article will introduce the cleaning and maintenance methods of emery floor. •◆• Emery floor cleaning 1. Remove surface debris: Use a broom or vacuum cleaner to remove dust, sand and other debris on the ground to ensure that the ground is clean and tidy. 2. Use neutral cleaners: Choose neutral or weakly alkaline cleaners and avoid using strong acid and alkali cleaners to avoid damage to the floor. 3. Wet cleaning method: After diluting the detergent, apply it evenly on the ground with a mop or floor washer, then rinse it with clean water and finally use a water absorber to absorb the water. 4. Dry cleaning method: For minor stains, you can use dry cleaning powder or sandpaper to gently wipe them, and then use a vacuum cleaner to absorb the stains and dust •◆• Emery wear-resistant floor maintenance 1. Regular cleaning: It is recommended to clean at least once a day to keep the floor clean and tidy. For special stains such as oil stains and chemicals, they should be cleaned in time to avoid remaining for a long time. 2. Avoid heavy pressure and scratching: Avoid heavy objects, sharp objects, etc. from direct contact with the ground to avoid scratching or damaging the ground. If heavy equipment needs to be moved, it is recommended to lay protective mats on the floor or use roller devices. 3. Regular maintenance: Regularly check the wear and tear of the floor. If necessary, perform partial repairs or overall renovation. At the same time, the floor can be polished regularly to restore its gloss and anti-slip properties. 4. Control humidity: Maintain appropriate indoor humidity and avoid the ground from being too wet or dry. Too much moisture may cause problems such as mildew and deformation of the ground; too much dryness may cause the ground to crack and fall off. To sum up, the cleaning and maintenance of emery floor need to be carried out regularly to maintain its beauty and usability. At the same time, care must be taken to avoid damage to the ground during use to extend its service life.

    The laser system of the concrete laser leveling is the core for achieving high-precision screing. Once a malfunction occurs, it will lead to a decrease in the leveling accuracy and affect the construction quality. The following are systematic and common troubleshooting steps. It is recommended to follow the principle of "from simple to complex and from outside to inside". Stop the machine immediately: Turn off the leveling machine and make sure the laser emitter is also turned off to prevent the laser from causing harm to the eyes. Confirm whether the battery power of the laser transmitter and receiver is sufficient. Low battery power can cause unstable signals. Check all cables and plugs for any damage, looseness or poor contact (especially the connection line between the receiver and the main unit of the leveler). Laser receiver: Clean its sensing panel to ensure there is no cement slurry, dust or oil stains covering it. Laser emitter: Clean the emission window to ensure the lens is clean. Mast/Benchmark: Check whether the mast on which the receiver is installed is vertical, stable and free from deformation. Confirm the status of the transmitter Make sure the laser emitter is turned on and in the rotating (sweeping) mode. Check if it is level (observe the bubble level it comes with). Listen to the sound and observe: During normal operation, there should be the sound of the motor rotating, and a moving red dot can be seen on the obstacle when the laser beam appears. Height and position inspection Height: Ensure that the receiver is within the effective working height of the laser plane (usually, the laser plane is best at the middle position of the receiver's sensing rod). If the receiver is too high or too low, no signal will be received. Location: Move the receiver directly near the laser emitter to see if there is a signal. If it is present near but not far away, it might be that the laser plane is blocked or the emitter is not level. Interference screening Check whether there is strong direct sunlight, other laser equipment or strong light source interference in the work area. Try to cover the receiver with a light shield. Equipment replacement test (if conditions permit) : Test with a confirmed normal receiver, or take the faulty receiver to another normally working transmitter for testing. This can quickly determine whether the fault point is the transmitter or the receiver. Inspect the ground and foundation Is the laser emitter tripod set up on a solid and stable ground? The vibration or subsidence of the ground during the pouring process can cause the launcher to shake. Check whether the leveling machine itself shakes violently when moving. Check the mechanical connections Is the connection between the receiver and the mast, as well as the connection between the mast and the body of the leveling machine, firm? Any loosening will cause signal jitter. Check whether the connection hydraulic cylinder/hinge point between the scraper or rammer plate of the leveling machine and the body is too loose, causing free travel. Electrical interference Lay the cables of the laser system separately from the main power line and hydraulic line of the leveling machine to avoid parallel and close contact, so as to reduce electromagnetic interference. Environmental review Is there a large amount of dust and steam in the air? These will scatter laser, causing the signal to weaken and become unstable. High-temperature heat waves can also cause light refraction. Calibration check (the most common cause) : Transmitter calibration: Use the dedicated calibration tool provided randomly and follow the steps in the manual to check and calibrate the horizontal accuracy of the laser transmitter itself. This is the most crucial step. Receiver zero point calibration: At a reference point of known height (such as a pre-set reference post), perform the operation of "zeroing" the receiver or setting the reference height. Reference point and setting check Recheck whether the construction reference point (elevation) is accurate and whether the height set on the transmitter is correct. Confirm whether the mode selected on the control panel of the leveling machine (such as the "Leveling" mode) is correct. Mechanical system linkage inspection After the laser system gives the correct signal, check whether the hydraulic lifting system of the leveling machine responds promptly and accurately. Are there any problems such as clogged hydraulic valves or leakage inside the cylinder? The lifting action can be manually operated to test whether it is smooth and powerful. If none of the above steps can solve the problem, it may involve an internal fault: Transmitter: Internal level sensor failure, motor drive module damage, laser tube aging, etc. Receiver: Damaged sensing element, mainboard failure, etc. Contact the equipment supplier or professional maintenance personnel. Provide detailed fault phenomena and the troubleshooting steps that have been taken. Do not disassemble the core components of the laser emitter or receiver by yourself, especially since the laser emitter has precise optical components and high-precision sensors inside. Non-professional disassembly may lead to permanent damage or calibration failure. Proper storage: After use, clean the equipment thoroughly and store it in a dry, shockproof toolbox. Regular calibration: In accordance with the requirements of the operation manual, conduct official calibration of the laser system on a regular basis (such as every quarter or before the start of each major project). Battery management: Use original or high-quality batteries. Remove the batteries when not in use for a long time. Avoid impact: Handle with care to prevent the laser equipment from being subjected to severe impacts or drops. Observe the fault phenomenon → Power off for safety inspection → Cleaning and appearance inspection → Power supply and wiring inspection → Select the above path for troubleshooting based on the phenomenon (no signal/unstable/poor precision) → Try to replace the component for testing → Contact professional maintenance. Through the above systematic steps, the vast majority of common faults of the laser system of the concrete laser leveling can be solved.   Note: The parameters provided in this document are for reference only and are not mandatory.
