Do a good job before the pavement inspection and lay a good foundation
1, detect the ground water content
The ground water content was measured with a water content tester, the required standard for normal ground was <20%, and the floor requirement for laying geothermal floors was <10%. If the ground water content is too high, the floor will easily absorb water and expand, causing problems such as arching, drumming, and noise. Therefore, if the ground water content exceeds the standard value, dehumidification is required.
2, check the flatness of the ground
Use a 2M ruler on the ground to inspect the floor, and use a 3mm thick feeler to check the gap between the ruler and the floor. If it fails, it passes the test. Passed is unqualified. If the ground is uneven, it needs to be flattened with a spade blade. If the situation is serious, it should be re-leveled or self-leveling. If the pavement is not leveled and paved, it will cause problems such as floor collapse, warping, arching, and noise.
3, check whether the ground is solid
Tap the ground with a screwdriver shank or boring head to check for holes or flaking on the floor. If the ground is empty or peeling, you need to reprocess the ground. Otherwise, after laying the floor for a period of time, a sound may occur because the floor is not solid.
4, check the environment whether there are termites
Observe carefully whether there are termites around the room and the furniture. Before the floor pavement, be sure to do the termite inspection and precautions. Otherwise, the whole floor and even all the wood products in the house must be seriously damaged.
5, to avoid cross-mixing operations
Floor paving shall be carried out after the concealment works on the ground, ceiling projects, wall projects, and hydropower projects have been completed and accepted. Cross-operations will easily cause floor damage. If the wall works are not completed, dropping sand will cause ash and scratches on the floor. Problems such as paint and paint spilling on the floor and damaging the aesthetic appearance of the floor all require us to pay attention.
6, whether to do a good waterproof
The floor is afraid of water intrusion. After the water invades, the floor will be blistering, degumming, deformation and other issues, resulting in unusable. Therefore, it is necessary to check whether the waterproof measures are done well before paving. If there is any leakage in the house, the floor should be laid after the treatment.
7. Covert Project Consultation and Labeling
Warm reminder: Ask the owner to specify the location of the concealed project in the room and make an eye-catching mark to avoid damaging the embedded water pipes, air pipes, power lines and communication lines during construction.

Carbon brushes are one of the most commonly replaced power tool parts. This is because carbon brushes are wear items, meaning that through friction and use they will gradually wear away until they need replacing. Worn brushes are a common causes of intermittent motor function, reduced electric braking and reduced motor power. A worn-out brush will often be worn down near to the wire lead and can be cracked, pitted, or burned. When replacing carbon brushes, be sure to inspect your armature for burns, cracks, or other damage which can indicate larger motor problems.
