Phosphor bronze is a copper alloy containing tin and phosphorus with high wear resistance, corrosion resistance, good elasticity and thermal conductivity. These characteristics are very important in the application of paper scrapers, because the scraper needs to be in constant contact with the high-speed roller surface, remove excess coating or moisture, while not damaging the roller surface, but also durable, in the high-speed paper production line, the scraper is the "invisible guardian" that determines the paper quality and equipment efficiency. With its unique material properties, the phosphor bronze scraper is becoming the "secret weapon" of the industry upgrade! Here are five things that make it stand out
1, the advantages of phosphor bronze scraper compared with other materials (such as stainless steel or ordinary bronze), or emphasize its effect in practical applications, such as extending service life, reducing downtime, etc. In addition, for example, performance on high-speed paper machines, or stability when handling different pulp.
2, the high performance properties of the material, such as bond strength or fatigue resistance, echo previous repair techniques.
3, phosphorus bronze (CuSn8P) containing tin, phosphorus elements, hardness as high as HB 180-220, far more than ordinary bronze! In the face of high-speed friction on the roll surface of the paper machine, it can easily cope with fiber erosion and chemical corrosion, increase the service life by 2-3 times, and greatly reduce the frequency of tool change.
4, phosphor bronze has both high strength and flexibility, can closely fit the roll surface curvature, scraping uniformity increased by 30%! Whether it is coating amount control or moisture scraping, it can ensure that the surface of the paper is smooth and smooth, reducing defects such as "streaks" and "fog spots".
5, papermaking wet part environment is humid, chemical additives (such as starch, sizing agent) easy to corrod metal. Phosphor bronze has excellent acid and alkali resistance, pitting and stress corrosion resistance is significantly better than stainless steel, and long-term stable operation does not "drop the chain".
6, high-speed scraping friction heat, phosphorus bronze thermal conductivity of 75 W/m·K, can quickly transfer heat to the tool holder, avoid local overheating caused by deformation or coating off, ensure the dimensional stability of the scraper, extend the roll protection period.
7. Although the unit price is slightly higher, the phosphor bronze scraper has a long life, low failure rate, and the comprehensive maintenance cost is reduced by 40%! At the same time, reduce the paper scrap rate caused by the failure of the scraper, and help enterprises to achieve a win-win situation of "reducing cost and increasing efficiency".
Industry feedback:
"After replacing the phosphor bronze scraper, the number of knife changes per month is reduced from 4 to 1, and the paper grade A rate is increased by 15%!" -- Jinan Tianmeng paper scraper is worth having.
