What are the differences between polyester filter bag laminating and non-laminating?Here's how to answer for you!
Polyester filter bags are a widely used filter material that is commonly used in various industrial filtration fields. Coated and uncoated are two common forms of polyester filter bags, and they have certain differences in filtration performance, use experience and cost. This article will introduce in detail the difference between polyester filter bag laminating and non-laminating.
1. Filtration performance.
1.Filtration accuracy: The filtration accuracy of polyester filter bag coating is high, which can reach the micron level, which is suitable for fine filtration. Non-coated polyester filter bags have a relatively low filtration rating, usually in the millimeter range, and are suitable for general filtration needs.
2.Air permeability: The coated polyester filter bag has good air permeability, which can reduce the filtration resistance and improve the filtration efficiency. The non-coated polyester filter bag has relatively poor air permeability, large filtration resistance, and is easy to cause large pressure loss.
3.Temperature resistance: The polyester filter bag coating has strong temperature resistance and can be used in a high-temperature environment, and the common use temperature can reach about 150. The temperature resistance of polyester filter bags without film is relatively poor, and the use temperature is generally not more than 80.
2. User experience.
1.Cleaning and maintenance: Polyester filter bag lamination is easy to clean and maintain, not easy to be contaminated with dust and impurities, and can prolong the service life. Polyester filter bags that are not coated with film are more susceptible to dust and impurities, making them relatively difficult to clean and maintain.
2.Strength and durability: The non-coated polyester filter bag has good strength and durability, and is not easy to break and deform. The coated polyester filter bag is relatively poor in terms of strength and durability, but it is suitable for use in specific environments because of its good air permeability and temperature resistance.
3. Cost. 1.Material cost: The cost of materials required for polyester filter bag lamination is relatively high because of the need for additional plastic film for covering. The cost of polyester filter bag material without film is relatively low.
2.Processing costs: Coated polyester filter bags require additional processing steps, so processing costs are also relatively high. Polyester filter bags without film are relatively simple to process and have a low cost.
There are obvious differences between polyester filter bag coated and non-coated in terms of filtration performance, use experience and cost. When choosing, users can weigh according to their actual needs and choose the products that are suitable for them. For example, for occasions that require fine filtration, high-temperature environments, or are prone to contamination, polyester filter bag laminated products can be selectedFor occasions with high strength requirements and general filtration needs, polyester filter bag products without film can be selected.
