What are the Industrial Use of Wood Chipper and Tensile Tester?
Paper testing equipments are used to provide accurate measurements and durability. There are various manufacturers, suppliers and exporters of paper testing equipments across India. They design and customize the paper testing equipments according to the need of their clients. Wood chippers are also a part of paper manufacturing industry.
Wood chippers are widely used for preparation of chips from wood, for lab and educational purposes. They are mainly used to slash fallen tree limbs, branches, used in preparation of chips from wood, bamboo and other similar materials. There are various types of wood chippers such as drum chipper, disk chipper, screw chipper etc. Wood chippers can lead to faster timbering, chipping and delivering it within due time to its customers.
Tensile tester is a machine that is used to quantify extreme elasticity, prolongation and decrease in the crossectional zone of the material by subjecting it to hub compel.
The test is carried out to know how a material will react to different type of forces in the field so that weakness are pointed and necessary remedial measures are taken to prevent failure in manufactured goods.
Microprocessor based tensile testing machines provide user friendly software which can guide a user to follow required steps of program selection, parameter change and test to limit human mistake amid test to give quick and productive assurance of tensile strength, stretch and tensile energy absorption.
Four circulation digester
Four circulation digester is a complex tubular reactor where wood chips react with an aqueous solution of sodium hydroxide and sodium sulfide to remove the lignin from the cellulose fibers.
Many a times in a four circulation digester mechanically processed paper is combined with paper made by chemical processing. Chemical processing makes use of heat, pressure and chemicals to dissolve the lignin in the wood, which releases the fibers of cellulose. After cooking in a special industrial digester for a period of time, 90 to 95% of the lignin and other non-cellulose ingredients are removed. This is also known as the “kraft” process.
