Let’s talk about the surface cleaning and maintenance of polyurethane screen plates.
In order to maintain the purity of certain materials and reduce impurities, polyurethane screen plates often use some filtering equipment, such as screen cylinders. For it, cleaning and protecting its appearance is a maintenance job. How to clean and maintain its surface?
- 1. Clean the appearance of the screen drum, being careful not to scratch the appearance of the screen drum. When this happens, avoid using washing liquid, steel balls and abrasives containing bleach and abrasives. Then, when the washing liquid is disconnected, use Rinse the exterior with clean water,
- 2. To simply remove external dust and dirt, wash with dilute detergent or warm water.
- 3. Bleaching the screen cylinder and various acids, rinse it with water immediately, then soak it in ammonia solution or neutral carbonic acid soda solution, and clean it with mild detergent or warm water.
- 4. There is a trademark on the outside, which can be washed with warm water and fragile detergent. The appearance of the screen cylinder contaminated by grease, oil and lubricating oil should be cleaned with soft cloth paint first, and then cleaned with neutral detergent or ammonia solution.
When the screen drum is running, its appearance will often come into contact with materials and the external environment, so it is very important to clean and protect the appearance while avoiding scratches.
Why does the polyurethane screen plate break?
The standard of the polyurethane screen plate is too long, and the screws are difficult to tighten. When selecting the grid, you should choose a ratio. The jagged edge shape does not meet the standards of the polyurethane screen and the tension plate; the degree of tension is questionable, and the tension plate does not match the screening machine. , The tension plate (hook) is worn, thinned or deformed.
The rubber pads are worn or empty; there are defects in the planning and construction of the screen and screening machine; welding cracks in the screen body cause structural damage to the screen body.
The polyurethane screen plate has uneven stiffness; the support rod of the screen mesh is lower than the screen mesh, that is, there is a certain interval between the support rod and the screen mesh to increase the strength of the screen plate.
The formation of polyurethane sieve plates is an important step in the hole making process. The formation of sieve plates is affected by many factors. First of all, we must pay attention to the impact of material properties on the selection of sieve plates. When forming sieve plates, the standard size of the sieve holes should be determined. , and set reasonable sieve holes according to the particle size and properties of the sieve material. Secondly, the adjustment method of the sieve plate grinder is a factor that affects the sieve plate forming. The relative direction of the upper and lower molds is determined by the guide device. If the equipment is not started.
In the process of forming the sieve plate habit, we also briefly introduced the phenomenon of sieve plate clogging, so we should pay attention to the direction of the aperture, so that the small holes face up and the large holes face down. If it is clogged, it is generally necessary to rectify the process and add a grinding elevator to allow Fine-grained materials are ground directly, and these aspects should be paid attention to during processing.
