What is spinneret?
Spinners are mainly used in industries such as textiles, synthetic fibers, glass fibers, plastic films, etc., for the production of various filamentous products. The use of spinnerets can increase production, improve quality, and increase efficiency, and is widely applicable, energy-saving, environmentally friendly, and easy to maintain。
As an important component of textile equipment spinning machine, spinneret has its unique advantages and disadvantages. The following is a detailed analysis of its advantages and disadvantages:
advantage:
1. High precision machining: The spinneret processed by high-precision machine tools can ensure excellent dimensional accuracy, roughness, and geometric shape, providing a foundation for producing high-quality fibers.
2. Excellent material: The spinneret is usually made of high-strength and corrosion-resistant materials, such as stainless steel, carbon steel, and aluminum alloy, which have the advantages of corrosion resistance, high hardness, low long-term deformation, and good sealing performance.
3. Wide application: The spinneret realizes the uniform distribution of spray based on the principle of liquid surface tension, and is widely used in textile dyeing and printing. It can form a uniform spray to achieve the uniformity and perfection of dyeing and printing.
4. Precise control: The electronic control system of the spinneret can achieve precise control of color depth and pattern shape by adjusting the nozzle position and flow rate, meeting different production needs for the melt blown filter cartridge spinneret.
5. High production efficiency: The spinneret has high production efficiency and can quickly process large quantities of textiles, improving production efficiency.
Disadvantages:
1. Cost factor: Although stainless steel spinneret has good anti-corrosion performance, the cost of melt blown filter cartridge spinneret is relatively high, which increases production costs.
2. Easy to corrode: Carbon steel spinnerets have a lower cost, but are prone to corrosion and require rust prevention treatment, which increases maintenance costs.
3. Material limitations: Although aluminum alloy spinnerets are lightweight and easy to install, they cannot come into contact with substances with strong oxidation properties, making them susceptible to corrosion and limiting their range of use.
4. Requirements for operating the melt blown filter cartridge spinneret: When using the spinneret, the operator needs to receive professional training to master the operation skills and safety knowledge of the spinneret, in order to ensure the smooth production process of the melt blown filter cartridge spinneret.
5. Service life: During long-term use, the spinneret may experience wear and deformation due to environmental factors such as high temperature and pressure, which can affect its service life and the stability of the melt blown filter cartridge spinneret. According to the information in the reference article, the service life of polyester spinneret is about 6000-8000 hours (250-300 days), which means that it will be scrapped after about one year of cumulative use.
How to choose spinneret?
1. Manufacturer power : Choosing a strong manufacturer can ensure the quality and after-sales service of the spray nozzle, avoiding problems that cannot be solved in a timely manner during use.
2. Product quality: The spinneret needs to work in high temperature and high pressure environments, so it needs to have pressure resistance, corrosion resistance, and sufficient mechanical strength to ensure long-term stable operation. The working environment of the spinneret is relatively harsh, so it is necessary to choose high-quality products
3. Diameter and holes number : Different apertures and numbers of pores can affect the thickness and yield of silk, and the selection of diameter and number of holes needs to be based on actual needs, which directly affects the yield and quality of the product.
The smaller diameterthe finer the silk produced, but the yield may be lower; The more holes there are, the higher the production efficiency, but it requires more maintenance and management.
4. Applicable raw materials: Different spinnerets are suitable for different raw materials. Choosing the appropriate spinneret can ensure the production of products that meet the requirements.
5. Production efficiency: High efficiency spinnerets can shorten production cycles and improve overall production efficiency. Need to choose a spinneret that is suitable for your own production efficiency
We also need to pay attention to the following issue
1. The existing spinneret melt spinning produces white spots around the wire outlet every 24-72 hours, which affects product stability and requires production to be stopped for "board repair operations". Although the enterprise's automatic punching machine replaces manual operations, it cannot solve the fundamental problem.
2. During the production process, the outlet surface of the micro holes in the spinneret will be worn and deformed into a trumpet shape after being sprayed by the melt, which has a significant impact on product quality. Therefore, it is necessary for the enterprise to replace the damaged spinneret in a timely manner.
3. As for the current irregular plates, with the increase of differentiated products from enterprises, the specifications of irregular plates have also increased. However, due to the processing of production enterprises, many irregular plates have rough surfaces, which increases the breakage rate of spinning and reduces the rate of high-quality products.
4. The component is the core of spinning, and the spinneret is the core of the core. Its quality directly affects the production stability, product breakage rate, and waste silk generation of the enterprise.
5. In addition to improving the quality of the spinneret, some seemingly "small" issues are also very important for users. For example, some companies currently produce spinnerets without production dates, which poses difficulties for later data statistics such as filing, recording usage time, and calculating elimination rates. Starting from the details when making products, it is important to label the manufacturer's trademark, production date, specifications, irregular pore size, leaf length, leaf width, and production time.
6. The quality and processing methods of the spinneret are closely related to the materials used, which directly affect the deformation of the micropores and the service life of the spinneret. Equipment companies should focus on improving these two aspects. Acquiring an automatic monitoring device for the spinneret allows for systematic management and detection of the spinneret, including tracking of usage time, air variability, and shaded areas.
