What are the advantages of beef tendon board?
Most of the construction site materials of the beef tendon board are stored in the open air, which is different from the warehouse storage method, but it is necessary to strengthen the accounting, card and material management in a safe, complete and clean manner. According to the performance of the material, other storage measures are taken to reduce loss, prevent waste, facilitate receiving and dispatching, and benefit the project.
What are the advantages of beef tendon board?
1. The beef tendon board has good abrasion resistance and long life. The abrasion resistance is 3 to 5 times that of steel sieve plates and more than 5 times that of ordinary colloidal plates.
2. The maintenance workload is small, the polyurethane screen is not easy to damage, and the service life is long, which can greatly reduce the amount of maintenance and the loss of maintenance.
3. The total cost of the beef tendon board is lower, but the one-time investment (about 2 times) of the polyurethane sieve plate of the same specification (area) is higher than that of the stainless steel sieve plate, but the life of the polyurethane sieve plate is 3 to 5 times that of the stainless steel sieve plate. The number of repairs and replacements is small, so the total cost is not high, and it is economically cost-effective.
4. The beef tendon board has good moisture resistance and can work with water as a medium. In the case of water, oil and other media, the friction coefficient of polyurethane and materials will be reduced, which is more beneficial to the body, improves the screening efficiency, and prevents wet particles Adhesion, the friction coefficient is reduced, and the service life is increased.
5. Corrosion resistant, non-flammable, non-toxic and tasteless.
6. Because the design of the body hole is reasonable, the body plate manufacturing process and size-restricted particles will not prevent the body hole.
7. The beef tendon board has good dust absorption performance and strong noise reduction ability, which can reduce noise and prevent the body from being easily broken during vibration.
8. The secondary vibration characteristics of polyurethane make the polyurethane screen have a self-cleaning effect, and the screening efficiency is high.
9. Energy-saving consumption is reduced. Polyurethane has a small specific gravity and is much lighter than a steel body of the same size. Therefore, it can reduce the load on the body, save power consumption, and extend the life of the body.
What is the production process of beef tendon board?
1. Preliminary polymerization synthesis
Raw materials, oligomer polyol 3360ODX2218, CMA21024 polytetramethylene glycol (PTMG 1000), dehydrated before use, the water content is less than 0.05%. Polyisocyanate: toluene diisocyanate (TDI2100). Synthesis of Prepolymer Cool the dehydrated oligomer polyol to 40 ~ 60, put it into the reactor, continue to mix the metered toluene diisocyanate, react for 30min ~ 40min and then slowly heat to (80), 2H ~ 3H
2. Casting process
In the pretreatment of the metal frame of the beef tendon plate, in order to make the polyurethane screen plate have a certain degree of rigidity during use, the screen plate is usually lined with a steel frame. Most of the steel skeletons of small and medium-sized screens are welded frame structures, and the tension screen uses multiple strands of steel wire as the skeleton. Taking into account the complex working environment, the surface of the metal frame needs to be sanded to remove the oil and rust on the surface, activate the surface, and expand the bonding area.
3. Mold assembly The steel mold is put into the skeleton after the surface demolding treatment, and the platform temperature rises to 110C.
4. Casting extension agent for polyurethane screen: chlorine, diaminodiphenylmethane (MO2 CA). Due to different production conditions, specific pouring methods are divided into manual pouring and mechanical pouring.
