Q:The influence of bag dust removal on dust filtration: The filter speed V (or than the load QF) is an important technical and economic index representing the capacity of the bag filter to treat gas. The selection of filtration rate should take account of economy and the requirement of filter efficiency. From the economic considerations, the filtration rate is high, with the same flow gas required filter area is small, then the size of the dust remover, the area, the steel consumption is also small, so the investment is small, but the pressure loss, power consumption, damage dust filter increases, because of high operating costs. From the aspect of dust filtration efficiency, the influence of filtration rate is remarkable. Some experiments show that the filtration rate increases by 1 times, and the dust passing rate may increase by 2 times or even more than 4 times. So the filter speed is usually expected to be lower. The filter speed of the fabric filter cloth is 0.5 ~ 2m/min, and the felt filter material is 1 ~ 5m/min. From the two aspects of economy and efficiency, this filter speed range is the most appropriate. When the filtration rate increases, it will intensify the penetration of dust particles by three ways, namely, through, extrusion and air holes, thereby reducing the dust removal efficiency.

Q:How does fiberglass fabric perform in water repellency?: Fiberglass fabric performs exceptionally well in terms of water repellency. The fabric is made from woven glass fibers, which are naturally hydrophobic in nature. This means that water molecules are unable to penetrate the fabric easily, resulting in excellent resistance to water absorption. The hydrophobic properties of fiberglass fabric make it ideal for applications where water repellency is crucial, such as in the production of outdoor clothing, tents, and boat covers. When exposed to water, the fabric remains relatively dry and does not become heavy or waterlogged. Additionally, the construction of fiberglass fabric allows it to maintain its water repellency over time. The fabric does not easily lose its hydrophobic properties, even after repeated exposure to water or washing. This durability makes fiberglass fabric a reliable choice for applications where long-term water resistance is required. However, it is important to note that while fiberglass fabric is highly resistant to water absorption, it is not completely waterproof. In extreme conditions, such as heavy rain or prolonged submersion, some water may eventually seep through the fabric. Nonetheless, fiberglass fabric still outperforms many other materials in terms of water repellency and remains a popular choice in various industries.

Q:Is fiberglass fabric resistant to tears and punctures?: Yes, fiberglass fabric is known for its high resistance to tears and punctures. It is a durable material that can withstand significant force and pressure without easily tearing or puncturing.

Q:What's the quality of waterproof made of fiberglass fabric and waterproof coating?: Terrace with waterproof coating, flexible waterproof better, but the cost slightly higher, glass fiber cloth cheap, but the quality is worse

Q:How do fiberglass fabrics perform in terms of breathability?: Fiberglass fabrics are not known for their breathability. Due to their inherent properties and manufacturing process, fiberglass fabrics tend to have a relatively low level of breathability. The tightly woven nature of fiberglass material restricts the passage of air and moisture through the fabric, resulting in decreased breathability. This lack of breathability can cause discomfort and excessive perspiration when wearing fiberglass fabric in warm or humid environments. However, it is important to note that fiberglass fabrics are primarily used for their durability, strength, and heat resistance, rather than their breathability.

Q:What are the different widths available for fiberglass fabric?: The different widths available for fiberglass fabric can vary, but common options include 1 inch, 2 inches, 3 inches, 4 inches, and 6 inches. However, these widths can be customized based on specific requirements and applications.

Q:Are fiberglass fabrics available in different colors or finishes?: Yes, fiberglass fabrics are available in different colors and finishes. While the natural color of fiberglass fabric is typically a white or off-white, it can be dyed or coated to achieve various colors and finishes. Dyeing fiberglass fabrics involves using specific colorants that can penetrate and bond with the fibers, resulting in vibrant colors. These colored fiberglass fabrics are often used in applications where aesthetics are important, such as in the production of clothing, home decor items, and automotive interiors. Additionally, fiberglass fabrics can also be coated with different finishes, such as silicone, acrylic, or polyurethane, to enhance their performance characteristics or provide specific properties like water resistance, heat resistance, or chemical resistance. The availability of different colors and finishes in fiberglass fabrics allows for a wide range of creative and functional applications.

Q:How does fiberglass fabric perform in chemical exposure?: The performance of fiberglass fabric in chemical exposure is exceptional. It is widely used in various industries where exposure to corrosive substances is expected, thanks to its inherent resistance to a wide range of chemicals. The fabric is composed of woven glass fibers, which create a strong barrier against chemical attack and degradation. Fiberglass fabric can withstand exposure to acids, alkalis, solvents, and other corrosive chemicals without significant damage or deterioration in many cases. This resistance to chemical attack makes it an excellent choice for chemical storage tanks, pipes, ducts, and equipment linings. Furthermore, the fabric's non-reactive nature prevents contamination or leaching of chemicals into the surrounding environment, making it a safe and reliable option for handling hazardous substances. Additionally, its thermal insulation properties enhance its performance in chemical exposure by providing protection against extreme temperatures that may accompany certain chemical processes. However, it is important to consider that the specific performance of fiberglass fabric in chemical exposure may vary depending on factors such as the type and concentration of the chemical, as well as the duration and temperature of exposure. Therefore, it is always advisable to consult manufacturers or industry experts to ensure the suitability of fiberglass fabric for a specific application and to determine any necessary precautions or compatibility considerations.

Q:What are the different types of fiberglass fabrics?: Various types of fiberglass fabrics are available, each possessing its own distinctive characteristics and applications. Some commonly used types include: 1. E-Glass Fabric: This particular fiberglass fabric is widely utilized due to its exceptional electrical insulation properties and high tensile strength. It finds application in boat construction, automotive components, and aerospace parts. 2. S-Glass Fabric: S-glass fabric is a superior alternative to E-glass, offering higher tensile strength and better impact resistance. It is suitable for applications demanding superior strength, such as military equipment and high-performance sports gear. 3. C-Glass Fabric: C-glass fabric is resistant to chemical corrosion, making it ideal for applications where exposure to chemicals is a concern. It is commonly employed in chemical plants, wastewater treatment facilities, and other industrial settings. 4. A-Glass Fabric: A-glass fabric is an alkali-resistant type of fiberglass fabric extensively used in the construction industry to reinforce cement and concrete structures, including bridges and buildings. 5. Roving Fabric: Roving fabric consists of untwisted fiberglass strands and is typically utilized in applications requiring high strength and dimensional stability, like wind turbine blades, pipes, and pressure vessels. 6. Chopped Strand Mat (CSM): CSM is a fiberglass fabric composed of randomly oriented chopped strands held together with a binder. It is commonly employed in applications requiring a smooth and uniform surface finish, such as boat hulls and automotive parts. 7. Woven Roving: Woven roving is a heavy-duty fiberglass fabric characterized by closely woven strands. It is renowned for its high strength and stiffness, making it suitable for applications necessitating structural reinforcement, such as boat hulls, wind turbine blades, and automotive body panels. Ultimately, the selection of fiberglass fabric depends on the specific requirements of the application, encompassing strength, electrical insulation properties, chemical resistance, and surface finish.

Q:When decorating, how can the waterproof of kitchen and toilet be checked and accepted?: Do closed water test. The kitchen and bathroom were filled with water up to 20cm high. For 24 to 48 hours of closed water test, the water level was observed to drop significantly and to see if there was any water seeping from the ground floor. For the light wall, the water is detected to see if there is water leakage on the back.
