INTRODUCTION TALKING POINTS CONCERN ABOUT THE GLOBAL ENVIRONMENT CONSERVATION OF FORESTRY RESOURCES MEETING CONCERNS AND INCREASING EFFICIENCY WITH NEW PROVEN TECHNOLOGY THE GLOBAL CHALLENGE
THE GLOBAL CHALLENGE NO LONGER CAN WE ASK THE QUESTION: WHICH IS MORE IMPORTANT SAVING MONEY, OR SAVING THE ENVIRONMENT? WE NO LONGER HAVE TO THANKS TO ECORNTECH AND OUR PARTNERS HERE TODAY JINSHANLIN TECHNOLOGY DEVELOPMENT CO
TECHNICAL OVERVIEW Introduction -. Cornstalk is a potential inexpensive source of quality fiber that can be used in paper industry for quality paper products and fiber board. -. Cornstalk offers the most promising fiber source which contains very little and/or no silica in the fiber matrix. -. Cornstalks are not at all used in pulp and paper industry, although nearly 284 million tons/year are available worldwide, including 130 million tons/year in China.
TECHNICAL OVERVIEW Comparison of Fibers Compared to the wood pulp, the corn pulp has more cellulose and less lignin and appropriate to paper manufacturing. Its fiber length is a little longer than the hardwood and its yield (45-55%) is almost the same when our chemical pulping methods are applied. Soft Wood Cornstalk Hardwood Fiber length yield Cellulose content Lignin content
TECHNICAL OVERVIEW -. Cornstalk pulping process needs less chemical, lower temperature, less time than wood pulping for similar yield. -. Cornstalk pulp needs less bleaching chemicals and fewer stages than wood pulp bleaching. Cornstalk pulp manufacturing process Our procedure Compression bailing transportation Compression chip transportation Baling compression Cornstalk Harvesting Chipper or refiner Chip storage and compression
TECHNICAL OVERVIEW Comparisons of Papers from Cornstalk and Wood Chip Cornstalk pulp could provide quality printing and writing grade paper with compare with wood paper Sample Basis weight (g/m 2 ) Density (kg/m 3 ) Diffuse Brightness (%) Printing Opacity (%) Tensile index (N · m/g) Stretch (%) Tearing Index (mN · m 2 /g) Wood pulp 80.4 698 87.4 89.8 12.0 1.73 4.7 Corn stalk pulp 76.9 784 88.7 87.2 25.5 2.65 6.4

TECHNICAL OVERVIEW -. The cornstalk fiber exceeds the mechanical and physical property values for standard industrial grade of wood fibers. -. Processing cornstalk fiber consumes less energy and time than those required for wood fiber. -. The cornstalk fiber has the bright future for the cheapest source of fiber, saving energy and eco-friendly policies. Conclusions -. EcornFiber TM is the best answer for non-wood fiber.
