NOVEL WET END TECHNOLOGY SIMPLIFIES SYSTEM CHEMISTRY,IMPROVES PERFORMANCE,AND REDUCES ENERGY CONSUMPTION

摘要

Papermakers are continually searching for ways to improve operating efficiency and reduce energy costs.Paper machines are frequently dryer or drainage limited.They can also have sheet strength issues.Additionally,the desire to reduce basis weight,substitute fiber,and reduce the use of wet end additives further complicates matters.In today's competitive environment,papermakers require a comprehensive solution for such problems.Recently,Hercules introduced a series of products that provide a powerful combination of strength,drainage,retention,and charge control.In addition to enhancing sheet strength,increasing speed,improving retention/drainage,and reducing energy consumption,the technology makes wet end simplification a reality.It has allowed many papermakers to reduce or eliminate the use of certain wet end additives,including starch,drainage and retention aids,and charge donors.
