The application of pervious concrete floor in daily life

  The road surface under our feet is very flat. In fact, it is only after leveling that we can achieve the effect we see today. When it comes to leveling the ground, we must talk about the laser leveling machine, because the reason why the road surface is so flat now is inseparable from the efforts of the laser leveling machine. However, when we use the leveling machine to work, sometimes some abnormal conditions will occur, such as how to solve the problem of too high oil temperature? If the oil temperature of the hydraulic system of the laser leveling machine is too high, the viscosity of the oil will be reduced, the leakage will increase, the oil film of the lubricated parts will be destroyed, and the wear of the parts will be aggravated; at the same time, high temperature will also cause the sealing gasket made of rubber and other materials to age prematurely and damage. Therefore, it is very important to control the appropriate oil temperature. 1. Check whether the oil level in the oil tank is too low. Experience shows that high oil temperature is often caused by lack of oil in the oil tank, so it should be replenished in time when it is lacking oil. 2. Whether the hydraulic oil filter and circuit are blocked. 3. Whether the radiator is normal. If a large amount of dust adheres to the radiator, it may cause poor heat dissipation and increase the oil temperature. Since the working environment of the laser leveling machine is dusty, the radiator should be cleaned in time. 4. Is the quality of the hydraulic oil qualified? If the added oil quality is unqualified, the system oil temperature will also be too high. In addition, the hydraulic system is working when it is short of oil, which is easy to cause damage to the pump and motor. Therefore, after the oil shortage fault is eliminated, the operating status of the pump and motor should be checked, and the damaged parts of the pump and motor should be replaced if necessary. 1. After completing the leveling operation, perform routine maintenance operations in accordance with the contents of the routine maintenance procedures. 2. The working devices and motion mechanisms of the leveling machine that are in direct contact with the asphalt mixture during operation should be sprayed with diesel after the operation and then run for a period of time to remove the residual asphalt on it, so that it can operate freely and rotate flexibly. It is forbidden to spray diesel on the electronic control system and spiral wire to prevent fire and combustion when the power is turned on. 3. After the laser leveling machine is leveled, flush it with water to wash away the white material. After flushing, use waste hydraulic oil to lubricate the moving parts of the scraper conveyor chain, and apply anti-rust oil to the piston rod. Be careful not to flush water to the electrical and bearing parts to prevent short circuits and foreign objects from entering the bearings. 4. Clean and check the lifting and adjusting device of the laser leveling machine longitudinal slope meter, and lubricate the screw with grease. Apply grease to the floating arm slide rail. Grease each oil filling point until the joint overflows. For leveling machines with oil filling cups, observe the consumption and fill them up at any time. This is the first part of the small knowledge about the increase in oil temperature of laser leveling machines. We will continue to update it for you later. I hope that the content shared can help you solve the problem better. If you want to know more exciting information about leveling machines, please visit our official website at any time to inquire.

  The laser leveling machine has attracted the attention of consumers since its launch, which has a lot to do with its own role. The engine oil has the unique role of lubrication and wear reduction, cooling, sealing and leak prevention, shock absorption and buffering on the equipment. It is precisely because of these humanized roles that the equipment has been welcomed by consumers. During use, the engine oil can effectively reduce the wear of the equipment. The following laser leveling machine manufacturer will take you to learn about the six major roles of engine oil on the laser leveling machine in detail. ★ Lubrication and wear reduction: In recent years, in order to pursue a smoother and more perfect ground, more and more people use laser leveling machines for construction. The use of equipment construction can ensure that the entire ground is dense and uniform, which has been well received by the construction industry. The laser leveling machine needs necessary maintenance after using it for a period of time. During maintenance, engine oil has a very large effect on the laser leveling machine. There is very fast relative sliding between the piston and the cylinder, and between the spindle and the bearing. Therefore, to prevent the parts from wearing too quickly, an oil film must be established between the two sliding surfaces. As long as there is a sufficient thickness of the oil film, the surfaces of the relatively sliding parts will be separated, so as to achieve the purpose of reducing wear. ★ Cooling and cooling: The engine oil can bring heat back to the oil tank and then dissipate it into the air to help the water tank cool the engine. Cleaning and cleaning: Good engine oil can bring carbides, sludge, wear metal particles, etc. on engine parts back to the oil tank through circulation, and wash the dirt generated on the working surface of the parts through the flow of lubricating oil. ★ Sealing and leakproof: The engine oil can form a sealing ring between the piston ring and the piston to reduce gas leakage and prevent external pollutants from entering the engine. Rust and corrosion prevention: Lubricating oil can be adsorbed on the surface of the parts to prevent water, air, acidic substances and harmful gases from contacting the parts. ★ Shock absorption and buffering: When the pressure at the cylinder port of the laser leveling machine engine rises sharply, the load suddenly added to the piston, piston chips, connecting rod and crankshaft bearings will be very large. This load will be transmitted and lubricated by the bearings and will buffer the impact load. The relevant knowledge points shared by the laser leveling machine manufacturer for you are basically explained here. If you have good suggestions or opinions, you can contact us in time. We will have professional technicians to help you solve the problem. Thank you for your continued attention and support.

    In epoxy flooring construction, power trowels are primarily used for smoothing and leveling the concrete substrate. It is crucial to note that the requirements for the substrate in epoxy flooring differ significantly from those for ordinary hardened floors. While ordinary floors strive for a "shinier, better" finish, improper substrate preparation for epoxy flooring (such as excessive burnishing) can lead to delamination and peeling later on. The following are key precautions for using power trowels in epoxy floor substrate preparation: This is the most important point. Problem: High-speed power trowels at large blade angles can create a "singeing" or "smoothing" effect, forming an extremely dense, hard, and smooth metallic sheen layer (sealing layer) on the concrete surface. Consequence: This dense film seals the concrete's pores, preventing epoxy primer from penetrating and resulting in extremely poor adhesion. The flooring is prone to peeling off in large sections later on, almost like "peeling off" the skin. Consequence: This dense film seals the concrete's pores, preventing epoxy primer from penetrating and resulting in extremely poor adhesion. The flooring is prone to peeling off in large sections later on, almost like "peeling off" the skin. Recommendation: Only perform moderate polishing. Ensure a smooth surface, but maintain some microporous structure (presenting a matte or slightly textured finish). During the use of a power trowel, workers may spray curing agents to prevent excessive moisture evaporation. Note: Most oil-based or silicone-based curing agents are incompatible with epoxy resin. If curing is necessary, please use a water spraying method, or confirm that the curing agent is "removable" or "epoxy-compatible." Epoxy flooring is typically thin (1mm – 5mm), and it cannot conceal unevenness in the subfloor like a cement leveling layer. Procedure: Initial leveling must be performed using **float pans** to eliminate waviness during paving. Standard: For precision epoxy flooring, the smoothness error within a 2-meter straightedge range should be ≤ 2mm – 3mm. If the surface is not leveled during the troweling stage, expensive epoxy mortar will be required for later leveling. Blade Angle: Maintain a small blade angle. A larger angle results in more concentrated pressure, making it easier to create an overly dense finish. Intervention Timing: Finish the finishing process slightly earlier than for regular floor finishing. Stop the machine as soon as the surface is smooth and there are no obvious blade marks. Edge Treatment: Corners and column edges that the power trowel cannot reach must be smoothed by hand with a trowel; otherwise, these protrusions will be difficult to remove with a sander later. Even with a perfect trowel finish, surface preparation using a grinder or shot blaster is essential before applying the epoxy primer. Purpose: To thoroughly remove the laitance layer created by the trowel, exposing the internal sand-grain structure (similar to the texture of coarse sandpaper), achieving CSP 2-3 (concrete surface roughness grade) standards. If you are working as a base coat for epoxy flooring, the goal of using a power trowel is to achieve a **smooth, not glossy** finish.   Is your current work environment an indoor factory or an outdoor parking lot? Different environments have different requirements for the moisture content and strength (C25/C30) of the base coat. I can provide you with more detailed advice.   Note: The parameters provided in this document are for reference only and are not mandatory.
