Publish Time: 2024-08-21
The performance requirements of alkali plain weave in industry are mainly as follows:
1. Physical properties
Strength:
High tensile strength: In industrial applications, alkali plain weave needs to withstand certain tension and stress, so it should have high tensile strength to prevent easy breakage during use. For example, when used as a filter material, it should be able to withstand the pressure and impact of the fluid without damage.
Good tear strength: It has a certain tear resistance to avoid tearing during installation, use or external force. Especially in some harsh industrial environments, such as those that may be scratched and pulled during transportation and installation, alkali plain weave should be able to maintain structural integrity.
Dimensional stability:
Small changes in warp and weft dimensions: Under different temperature and humidity conditions and after processing, the dimensions of alkali plain weave should remain relatively stable. This is very important for some industrial applications with high dimensional accuracy requirements, such as when used as a sealing material or in precision equipment, dimensional changes may affect the performance and sealing effect of the equipment.
Good thermal stability: In high temperature environments, alkali plain weave should not shrink, deform or change in performance significantly. For example, in some high-temperature industrial processes, such as kiln linings and high-temperature pipe insulation, alkali plain weave fabrics need to be able to withstand high temperatures while maintaining their physical properties and dimensional stability.
Thickness uniformity: The thickness of the entire cloth surface should be uniform and consistent to avoid local over-thickness or over-thinness. This is essential to ensure the quality and performance consistency of the product. For example, when used as an electrical insulation material, uneven thickness may lead to uneven local electric field strength, thereby affecting the insulation effect.
2. Chemical properties
Alkali resistance:
Strong alkali corrosion resistance: In industrial environments, alkali plain weave fabrics may come into contact with various alkaline substances, such as sodium hydroxide and potassium hydroxide. Therefore, it must have strong alkali resistance and be able to be used stably for a long time in an alkaline environment without being corroded, degraded or losing its performance. For example, in chemical production, alkali plain weave fabrics used for filtering and separation of alkaline solutions should be able to resist the erosion of alkaline substances.
Chemical stability: In addition to alkali resistance, it should also have a certain chemical stability and tolerance to other common chemicals. For example, in some complex industrial environments, there may be multiple chemicals such as acid, alkali, and organic solvents at the same time. Alkali plain fabric should be able to maintain its stable performance in such an environment.
Flame retardancy (if required): For some special industrial applications, such as fire prevention and explosion prevention, alkali plain fabric may need to have certain flame retardant properties. When encountering open flames or high temperatures, it should not burn easily, and it can prevent the spread of flames to ensure the safety of industrial production.
3. Other properties
Breathability (if required): In some applications, such as when used as a filter material or ventilation material, alkali plain fabric needs to have a certain breathability to allow gas or liquid to pass through, while blocking solid particles or impurities. The size of the breathability should be adjusted according to the specific application requirements. For example, in air filtration, the breathability needs to be controlled to ensure the balance between filtration efficiency and air flow.
Wear resistance: In some industrial applications, alkali plain fabric may be subject to friction, wear, etc., so it needs to have a certain wear resistance. For example, when used as a conveyor belt or friction material, the alkali plain cloth should be able to withstand long-term friction without damage, maintaining its performance and service life.
Easy to process: The alkali plain cloth should be easy to cut, sew, bond and other processing operations to meet the needs of different industrial applications. For example, when making seals, gaskets and other products, it needs to be easy to process and shape, and the processed products should have good sealing and durability.
