What are the characteristics and advantages of polyurethane cleaners? Let's understand with the cleaner manufacturer:
Sweepers developed late in the country. Later, with the gradual development of the Chinese market, with the development of the industry in recent years, the quality and technical level of some enterprises’ products have reached or approached the international level, reflecting the strength and direction of the industry. Device.
Polyurethane scraper features:
The product adopts the properties of high wear resistance, high aging resistance, high solvent resistance, and long service life. Its Shore hardness is: 45A-95A. Scrapers are often used on coal chemical conveyor belts to scrape off adhering ash and powder materials, such as coal transportation, fertilizer transportation, and sand transportation. If the super wear-resistant polyurethane composite material is used, the service life of ordinary polyurethane is twice. Excellent wear resistance, the service life is 5 times that of general rubber and plastic products, and can be customized according to customer drawings. Our PU scrapers are all cast and formed. Various types of products have the characteristics of easy installation, maintenance, debugging, no damage to the belt, no holding, no sticking, good cleaning effect, good toughness, good straightness, and high wear resistance.
In the process of conveying materials by belt conveyor, if residual materials enter the roller or idler bearing housing, bearing wear will be accelerated, and the material on the surface of the roller or idler will tear and rough the surface of the conveyor belt, which will accelerate the wear and tear of the conveyor belt. destruction. If the material is attached to the roller at the tail of the belt conveyor or the surface of the vertical tension roller is attached and agglomerated, it will cause the conveyor belt to deviate, increase the abrasion of the conveyor belt, and even tear the rubber layer of the roller, causing serious consequences. If the cleaning device is effective, the service life of rollers, conveyor belts, rollers, etc. can be prolonged; therefore, the cleaning ability of the cleaner plays a decisive role in improving the operating efficiency and reliability of the belt conveyor, reducing equipment failure rates and reducing maintenance costs The role of. An effective cleaning system can clean the surface of the roller and the adherents on the bottom of the conveyor belt, prevent the conveyor belt from deviating, extend the service life of the conveyor belt and accessories, and prevent accidents. It is a necessary accessory for belt conveyor. Sweeper is the main part of belt conveyor widely used in steel, mining, dock, power plant and other industries. It can effectively protect the roller from damage.
The PVC cleaner has excellent scraping effect:
Polychloride cleaner scraper is made of polychloride composite material, which is formed by integrally vulcanizing with a mold. The scraper has a flat surface, good straightness, low friction, high wear resistance, high strength, and a stable scraping effect. Polychloride cleaner can effectively remove fine particles and wet sticky materials on the remaining belt. The pre-pressure regulator ensures stable contact pressure between the scraper and the belt. The scraper surface is composed of multiple narrow-width polyurethane scrapers with hollow buffer holes, which have good followability to various belts.
The scraper has no risk of jumping: the scraper and the fixed seat are combined with a dovetail groove, and there is a tightening device to eliminate the clearance. The three-layer scraper group has a detachable fixed seat, which can be replaced on the side of the hopper, and it is very easy to install or maintain. Tool holder replacement is simple and fast: the contact pressure is promoted and stabilized by the side of the blanking hopper, and can be fine-tuned if necessary.
Polychloride cleaner has a long service life: the low and stable contact pressure between the scraper and the belt can not only maintain the excellent scraping effect, but also effectively increase the service life. The scraper should generally be used for 1-3 years without damaging the belt.
