Do You Know the Role of Nylon Mesh in Building Ventilation Systems?

The main function of the waterproof steam veneer is to delay the speed of water vapor passing through the roof or wall assembly. Nylon mesh filter ribbons supplier  believes that there is no true waterproof vapor barrier that can completely prevent the passage of water vapor, but some waterproof vapor barriers are less permeable because of their lower permeability. Other veneers delay the penetration process even more. Permeability is measured in imperial perms (1 perms means 1 centimeter of water passes through an area of 1 square foot in 1 hour at a pressure difference of 1 inch of mercury) or nanometers per metric meter per pascal per square meter Centimeters to 1/7000 pounds). 1 perm is equal to 57.2 nanograms per square tear card per second per square meter. The velocity of the water vapor is equal to the water vapor pressure difference between the materials on both sides multiplied by the permeability of the waterproof veneer. The lower the permeability, the better th...

What are the Classifications of Polyurethane Screens? How to Choose?

Vibrating screen is an indispensable main equipment in beneficiation and classification operations. It has many specifications and models. In order to meet different classification and dewatering purposes, the structure, size, size and distribution of screen meshes are various. The screen surface is usually assembled by multiple screens. Traditional screens are usually made by punching, weaving or tailor welding. The material is carbon steel, stainless steel or alloy steel. The screen is severely impacted and worn by the ore, coupled with the high frequency of the vibrating screen, the welds are prone to fatigue and cracking, so the service life is short and the replacement is frequent, which seriously affects the production efficiency of the vibrating screen. Polyurethane elastomer products have properties such as wear resistance, oil resistance, aging resistance, tear resistance, impact resistance, high elasticity, strong vibration absorption and large load supporting capacity. ...

Factors Affecting the Life of Polyurethane Screens

Impact of unreasonable use on the life of  polyester screen mesh : After selecting the correct polyurethane screen, it needs to be used reasonably to ensure that the performance of the polyurethane screen is maximized and the life is maximized. However, many users tend to ignore this point when using the polyurethane screen. For example, the tensioned screen is easily loosened by large materials during use, and the tension bolts need to be tightened regularly. If the time is too long, the tension bolts become loose and not tightened, causing a knock between the screen and the support ribs. Affect the life of the screen. At the same time, there is a feed inlet design. It is recommended that the feeding method is not vertical to the screen surface. The feeding direction is oblique along the direction of the logistics. Polyester bolting cloth supplier  believes that the processing technology is the main factor that affects the quality of polyurethane screen materials with th...
