The polyester glass fiber cloth produced by our company is made of glass fiber and polyester fiber as the main raw materials and is made by advanced wet process. Glass fiber and polyester fiber itself is extremely widely used at home and abroad waterproof and reinforced materials, polyester fiberglass cloth is focused on the excellent characteristics of the two fibers: GF strength, heat resistance, aging, water resistance; PET flexibility, and get a "rigid and flexible" new materials, to overcome their shortcomings: brittleness, heat.

polyester fiberglass cloth instructions for use:

According to the following method of construction, paving polyester fiberglass cloth is very convenient.

◎ Cleaning work on the pavement to be paved with polyester fiberglass cloth: remove dirt, gravel and dust to ensure the asphalt bonding effect.

◎ When the foundation pavement has large cracks (more than 6mm), pits or damage, it should be repaired and filled.

◎ The adhesive oil layer used must be hot asphalt, emulsified asphalt cannot be used, otherwise the bonding effect of polyester glass fiber cloth will be reduced.

◎ The optimum temperature for bonding asphalt is 163-204 ℃.

◎ After the adhesive asphalt is spread, the polyester glass fiber cloth must be paved before the asphalt loses its fluidity, otherwise the cloth body is difficult to soak the asphalt and reduce the waterproof performance of the polyester glass fiber cloth.

◎ Paving polyester fiberglass cloth construction environment temperature must be above 4 ℃.

In order to achieve good results, pay attention to the following aspects when paving polyester glass fiber cloth:

◎ Polyester fiberglass cloth must be installed on hot asphalt. We recommend the following bitumens: AC-20;PG64-22;AR8000; or puncture grade 60-80. For extremely high temperature summer construction, recommend the use of relatively high viscosity asphalt, the following asphalt is more suitable for summer construction: AC-30;PG67-22;AR8000; or thorn such as grade 40-60 asphalt.

◎ The use ratio of asphalt is 1.1 liters/square meter, but according to the actual situation of the installed pavement and the expected overlap, the use ratio will have a range: 1.0-1.3 liters/square meter. It is not recommend to heat the asphalt in the transport vehicle above 204°C, as this will prevent the pre-maturation of the liquid asphalt.

◎ Be careful when loading and unloading polyester fiberglass cloth. If the cloth roll is dropped from the transport vehicle, it will damage the polyester fiberglass cloth, which will cause application problems.

◎ If stripes appear during installation, any stripes larger than 2.5cm in the paving direction must be cut and stacked, and the overlap shall be immersed in the asphalt layer by hand. The polyester fiberglass cloth must be rolled or brushed to ensure full contact with the road surface and to remove air bubbles. The applied width of the hot bitumen must be 4 inches further than the width of the polyester fiberglass cloth. Polyester fiberglass cloth is not easy to bend or stretch on curved surfaces. When installing the construction on the curved surface, the cloth can be cut short, and the installation can be carried out mechanically or manually.

◎ The installation of polyester fiberglass cloth can be carried out by a tractor or truck with a metal roller. The function of the metal roller is to ensure that the polyester fiberglass cloth is spread smoothly on the road surface. A row of brushes must be installed behind the installation roller to ensure that the polyester fiberglass cloth is compressed into the asphalt coating. The joint of polyester glass fiber cloth must ensure that there is a 5.1cm lamination layer in the length direction and a 10.2cm lamination layer in the width direction. The uppermost transverse joint must be in the direction of paving, and all joints must be lapped together.

◎ Paving machinery or other vehicles in the polyester fiberglass cloth installation in the above turn must be gradually unfolded, and must ensure that as little as possible to turn, in order to avoid possible damage to the cloth. During the spreading construction, the equipment tires must be attached to the cloth surface, and the cloth surface should be sprinkled with sand as little as possible to avoid adhesion. Do not reduce the amount of asphalt paving in order to reduce the adhesion of tires. It is a good practice to spread in the overlapping parts.

◎ The paved road can be opened to traffic after being determined by the contractor or the installation engineer.

Feature profile:

◎ Provide reliable waterproof effect

Polyester glass fiber cloth will not shrink and deform under the high temperature of asphalt concrete, which can completely avoid the deficiency of other materials. In this way, a continuous, complete and reliable waterproof layer without deformation can be formed under the hot mixed asphalt mixture pavement, which can effectively prevent the infiltration of gouache and avoid the damage of pavement layer and foundation layer caused by water infiltration.

◎ Crack resistance

Polyester glass fiber cloth has low elongation and high tensile strength, especially and asphalt bonding layer to form a strong reinforced composite material, which can effectively eliminate the stress concentration at the joint or crack of the pavement, reduce the spread of cracks in the pavement layer, thus prolonging the service life of the road and greatly reducing the maintenance cost of the road.

◎ Renewable

The main raw material of polyester glass fiber cloth is chopped glass fiber and polyester fiber, the structure is isotropic, different from the common textile structure, can be easily crushed, so as to realize the recycling of pavement materials, so the material is friendly to the environment.
