Tarpaulin products can be waterproof, four-leg single-fold heat sealing

Tarpaulin products can be waterproof, four-legged single-fold heat-sealing and heat-sealing, and the rope part is mainly fixed on the edge, and its application range is also very wide, so how to detect the density of the tarpaulin? The size of the density will directly affect the physical and mechanical indicators of the plastic tarpaulin's appearance, feeling, thickness, strength, anti-folding, air permeability, wear resistance and thermal insulation performance, so you must pay attention when purchasing.

The indirect test method is to analyze the fabric structure and the number of cyclic warp yarns in the weave, multiply the number of weave cycles in 10cm, and the product obtained is the warp (weft) yarn density. This method is suitable for regular fabrics with high density and small yarn characteristics. The direct measurement method is done through a cloth mirror or a fabric density analysis mirror. It should be noted that when counting the number of yarns, the center between the two yarns should be the starting point.

When buying tarpaulin products, the quality is what we should pay attention to when purchasing. The important feature of tarpaulin is waterproof, so we can try to pour a small amount of water on the surface of the product. If this water does not penetrate deep into the tarpaulin, the quality of the product is relatively good. The density of the tarpaulin must be one of the important factors. The method of product identification is very simple, that is, check the latitude and longitude of the product, the denser the product, the better the product quality.

Secondly, we should also pay attention to the roughness of the product surface. During the selection process, we can feel the roughness and softness of the product with our hands to determine the advantages and disadvantages of quality. If we want to buy a good tarpaulin, we can't try to be cheap. Although the quality and price of these products are not decisively linked, quality often accounts for a certain percentage of the product price. Generally speaking, the price in the same area is relatively high, so the quality of the product is better.

When the truck is driving on the highway and encounters bad weather such as strong wind and heavy rain, if the tarpaulin is not bundled properly, the air flow of the truck tarpaulin will cause the goods to spill during the driving process. This is very dangerous. Therefore, tarpaulins must be bundled up to ensure safety before hitting the highway. Let's take a look at how to fasten truck tarpaulins.

First of all, the pressure rope at each end of the tarpaulin should press the corner of the tent cloth, so that the tent cloth is close to the end wall of the vehicle, and respectively tied to a rope on the side of the vehicle, not to the towing hook.

Secondly, in the place where the truck is tied, it must not be tied to other parts. The tent rope should be converted to another word and then tied to the other end of the rope head. Pull the end of the rope with one hand. The rope can be used double rope for a long time, that is, fold the rope into two, and then tie it into a back flower. In other words, the rope should be tied with bows or bows. The tied end of the rope should be wrapped around its own pole with at least two dead knots. The length of the rope head and tail shall not exceed 300mm and shall not be less than 100mm.

The waist rope should be tied directly to the side rope of the vehicle. The stretched length of the elastic part of the elastic rope shall not be less than 200mm, which shall be determined according to the specific conditions of the loaded goods. If there is a rope in the middle of the vehicle, the waist rope in the middle is tied to the rope in the middle of the vehicle; if there is no rope in the middle of the vehicle, the waist rope in the middle of the tent cloth is tied to the rope 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 rim, the elastic rope should be folded from the middle, and the excess rope in the middle should be folded into two dead knots, tied with rope clips or twine for 5 loops, and tied tightly with your own rope rod.
