In the complex process of industrial production, although the hydrophobic sieve plate may seem like a small component, it plays a crucial role. It is like a precise barrier, ensuring smooth passage of materials and achieving efficient hydrophobic function. However, the two major "problems" of hole blockage and delamination often plague the production process, causing headaches for enterprises. Having a deep understanding of the process details behind it and mastering precise daily maintenance points becomes the key to ensuring stable production operation.

1、 Analysis of the causes of equipment blockage

1. Material characteristics causing trouble: whenHydrophobic sieve plateWhen dealing with materials with high viscosity or easy clumping, they are like "naughty children" and easily adhere to the sieve holes. Over time, layers accumulate and tightly block the sieve holes. For example, in some food processing industries, the viscosity of sugar and starch materials increases dramatically in high temperature and high humidity environments, which can easily lead to this situation. In addition, impurities such as fine fibers and hair contained in the material can also penetrate the sieve holes like needles, getting stuck and hindering normal circulation.

2. Unbalanced operating parameters: Unstable flow rate is a major hazard. If the flow rate is too fast and the material cannot be dispersed in time, it will rush towards the sieve plate one by one, causing local accumulation and leading to pore blockage; On the contrary, if the flow rate is too slow and the material stays on the sieve plate for too long, the solid residue left after water evaporation will also block the sieve holes. Pressure fluctuations should not be ignored. Excessive pressure can force materials into the sieve holes, damage the structure, and make it more difficult for subsequent materials to pass through; And the pressure is too low to push the material forward smoothly, resulting in blockage.

3. Environmental factors: When the humidity is too high, water in the air will condense into water droplets on the surface of the sieve plate, mix with the material, change its physical properties, become more sticky, and increase the risk of pore blockage. When the temperature changes dramatically, the thermal expansion and contraction effect will cause changes in the volume of the material, resulting in deviations in the size of the sieve holes that were originally adapted, either hanging on the wall or unable to fall off, leading to blockage.

2、 Exploring the root cause of equipment delamination

1. Manufacturing and installation "defects": During the production process, if the adhesive is not evenly applied and some areas are thick and some areas are thin, over time, the thin areas are prone to failure, leading to separation between the layers of the sieve plate. The degree of tightening during installation is also crucial. If the screws are tightened too loosely, the sieve plate will constantly vibrate during operation, increasing the interlayer friction and eventually detaching; If it is too tight, it may directly crush the edges, damage the sealing, and lay the groundwork for delamination.

2. Long term fatigue "damage": Continuously subjected to material impact and compression, the metal material of the sieve plate will gradually develop fatigue cracks. These tiny cracks were initially inconspicuous, but after repeated stress, they slowly expanded and extended until they connected into sheets, causing the sieve plate to peel off from the weak points. Especially in high-frequency vibration working environments, the speed of fatigue damage is faster.

3. Corrosion damage is difficult to prevent: When exposed to corrosive chemicals such as acid and alkali solutions, the protective coating on the surface of the sieve plate will be eroded and peeled off, and the unprotected metal substrate will be directly exposed. At the same time, the internal structure will be weakened, and the bonding force between different levels will be greatly reduced, resulting in delamination.

3、 Daily maintenance core strategy

1. Regular cleaning and maintenance: Develop a reasonable cleaning cycle based on the properties of the material. For viscous materials, rinse them with warm water in a timely manner after each use, and gently brush both sides of the sieve plate with a soft bristled brush to remove residue. Soak in specialized cleaning agents at regular intervals to deeply dissolve stubborn dirt. After cleaning, be sure to air dry to prevent moisture from causing secondary problems.

2. Optimize operating standards: Strictly control the feeding speed and pressure range of materials, use automated control systems to monitor and adjust in real time, and maintain smooth operation. Before the new batch of materials is put into use, samples should be taken and tested to evaluate the impact on the sieve plate, and measures should be taken in advance. At the same time, pay attention to changes in environmental temperature and humidity, and install air conditioning, dehumidifiers, and other equipment if necessary to create stable working conditions.

3. Strengthen inspection and maintenance: Assign a dedicated person to conduct daily inspections, check for any damage or deformation on the appearance of the sieve plate, and listen for any abnormal sounds during operation. Once a slight blockage is found, immediately stop the machine and carefully clear it with a fine needle; For early signs of delamination, mark the location and arrange for professional personnel to repair and reinforce as soon as possible. Regularly replace severely aged sieve plates and do not have a lucky mentality.

In short, in the face of the challenges of clogged holes and delamination in hydrophobic sieve plates, only by starting from the source, controlling every process detail well, and implementing daily maintenance can the hydrophobic sieve plate always maintain a good condition, and safeguard the efficiency and stability of production.
