The temperature of the water storage tank covered with the automatic tarpaulin cover of the dump truck is normal. Reason: We all know that we boil water in the teapot at home. Frequent boiling will form a thick layer of dirt in and around the pot, which will stick to the pot. Strong and difficult to remove. The water tank on the tarpaulin cover of the dump truck is not that thick, because once the engine is running, the water in the water tank is constantly circulating. But even then, if you continue to drain water, as time goes by, a layer of dirt will still form on the inner wall of the radiator pipe, which will affect the cooling effect of the engine covered by the dump truck tarpaulin and cause the temperature to rise. Once the dump truck automatic cover tarpaulin covers the inside of the water storage tank, you should find a professional to clean it. In addition to using steel wire to make the water tank completely transparent, you also need to soak it with a water tank cleaning agent that removes scale, stains, and rust. However, this kind of detergent has a very serious problem of corroding the water tank on the tarpaulin cover of the dump truck. We need to drain the water tank on the large truck in a minute or two, and then clean it with cold water immediately, otherwise it is likely to be damaged. The water storage tank was damaged, but the actual effect after cleaning was very good, no different from a new water storage tank.

1. Breathability The air permeability of the tarpaulin must be considered, especially for military tent fabrics. The factors that affect the air permeability include the base fabric structure, density, material, type of waterproof finishing agent, amount of resin adhesion, etc. As the amount of resin adhesion increases, the air permeability of the tarpaulin decreases. Of course this is related to the finishing agent used. Generally, most breathable tents are made of short woven fabrics such as cotton, vinylon, and lacquer that have been finished with paraffin or acrylic resin. 2. Tensile strength The tarpaulin must withstand various tensions when in use. For example, when it is tightened, it will be subject to tension; during use, it will be subject to additional forces such as wind, rain, and rain. Despite these external forces, they are still required to maintain their original shape and not be easily deformed. This requires the tarpaulin to have high tensile strength, and there should not be a large difference in tensile strength in the warp and weft directions. Especially for large tents used in inflatable buildings, the tensile strength is extremely important. Generally, the base fabric is made of high-strength polyester, vinylon and other long fiber fabrics. It is waterproofed with vinyl chloride resin and chlorosulfonated polyethylene resin. The strength of the product is mainly determined by the strength of the fiber material and the density of the fabric. 3. Elongation and dimensional stability As eaves tents and large tents, they are often used under tension. The fabric elongation should not be too large, and its dimensional stability is determined by the creep characteristics of the material. 4. Tear strength Tarpaulin damage is mainly caused by tearing, so tearing strength is an important indicator of tarpaulin. Tear strength is related to whether the tarpaulin will be broken due to the action of flying foreign objects or whether it will expand around after forming holes for some reasons, forming large structural cracks. So, when the tension is high. The tarpaulin is required to have both high tensile strength and high tear strength. 5. Water resistance Water resistance is an important characteristic of tarpaulin. Through dipping and finishing, vinyl chloride resin is filled in the gaps of the fabric tissue to form a coating film. If the amount of resin adhesion per unit area exceeds a certain level, water resistance is not a problem. If the coating film is thin, it will easily break when it is bent, rubbed, or worn on the surface, which may cause muddy water. 6. Flame retardancy From the perspective of safety, tarpaulins are required to have good flame retardancy. Flame retardancy can be obtained by selecting flame retardant fiber and flame retardant base fabric. It can also be achieved by adding flame retardant to the coating agent. The amount of flame retardant added is directly related to the flame retardant effect.

When using the tarpaulin, do not step on it directly with your shoes on, as this may damage the strength of the tarpaulin. Secondly, when using the tarpaulin, keep it dry. After use, hang the tarpaulin up to dry. If you find that there is dirt on the tarpaulin, If it is dirty, scrub it gently with water. Do not use detergents with chemical additives, and do not scrub hard. When using a new tarpaulin, you need to add a layer of seam glue to the waterproof seam glue. It may take a long time from the time the tarp leaves the factory to the time it is used, so you need to consolidate the waterproofing measures. When setting up, the tarpaulin should be fixed to the ground to prevent it from being unstable and collapsing if pressed with bricks. Note that the tarpaulin should be cleaned regularly to prevent it from becoming moldy and smelly, and do not use a washing machine to wash it. Do not brush hard to avoid short lines or brushing off the patterns and decorative parts of the shoe body. Pay attention to using gentle and even force when cleaning. , if you find that the plastic tarpaulin has any minor problems such as disconnection, disconnection, or loose decorative parts, it should be repaired in time to extend its service life. Be careful not to come into contact with items that are difficult to clean such as carbon ink. After cleaning the tarpaulin of this color, apply toothpaste or white chalk powder evenly and let it dry to prevent discoloration.

1. The pressure ropes at each end of the tarpaulin should press the corners of the tarpaulin and tighten it so that the tarpaulin is close to the end wall of the vehicle. They should be tied to the first rope on the side of the vehicle and should not be tied to the towing hook. 2. Tie it to the place where the rope is tied to the truck. Do not tie it to other parts. The tarpaulin rope should be turned into the word "and" and then tied to the other end of the rope head. Pull the tail of the rope with one hand. If the rope is long, double ropes can be used; that is, Fold the rope into two, and then tie it into a back-and-forth flower, or in other words, use the butterfly knotting method or the back-and-forth flower knot method to tie the rope. The rope end after being tied should be wrapped around its own rope pole and tied with at least two dead knots. ;The remaining length of the rope head and tail shall not exceed 300mm and shall not be shorter than 100mm. 3. The waist rope should be pulled straight and tied to the rope on the side of the vehicle. The stretch length of the elastic part of the elastic rope should not be less than 200mm, which is determined according to the loading conditions. If there is a rope in the middle of the vehicle, the middle waist rope should be tied to the vehicle. Tie the rope in the middle; if there is no rope in the middle of the vehicle, the waist ropes in the middle of the tarpaulin are tied to the ropes near the middle of the vehicle. The other waist ropes, starting from both ends of the vehicle and toward the middle of the vehicle, are tied to the corresponding ropes in sequence. . When the elastic rod is not close to the eye socket, the elastic rope should be put away from the middle, the excess rope in the middle should be folded and tied into two dead knots, and the remaining tail should be tied 5 times with a rope card or twine and tied to its own rope pole. 4. Except for the ropes and tarpaulin rope nets that come with the tarpaulin, other ropes are not allowed to be used to bind the tarpaulin. When the remaining ropes are long, they must be stuck and the ropes must not be allowed to go arbitrarily. 5. After being bundled, the plastic tarpaulin should be completely covered and flat, with the goods not exposed. The corners at both ends should be solid and dense, with smooth lines. Each part should not exceed the limit, be strong and not loose and fall off. Of course, the hand brake disc of the truck must be exposed. 6. The tarpaulin corner ropes at both ends of the truck cross along the end wall of the truck and are tied to the two ropes at the end of the vehicle. When the angle rope passes through the truck's manual brake gate, it should pass from above; when it passes through the brake lever and lifting hook rod, it should pass from the inside; at the same time, pay attention to the two end ropes in the middle of the tarpaulin at both ends of the truck that are vertically downward. Tighten the two ropes tied to the end of the vehicle. When passing the hook rod, it should also pass through it from the inside.
