Similarities and differences between paper making and paper holder production

Similarities between paper making and paper holder production:

(1) Production materials are basically the same. Both pulp molding and paper and board production can use the basic raw materials of paper making, such as reed, bagasse, wheat grass and other herbal fiber pulp or waste paper recycling pulp. The chemical assistant that uses in production process is basically same also, if help stay agent, help filter agent, wet strong agent, dry strong agent, waterproof agent, oil-proof agent, dye, whitener, still have the environmental protection paper that environmental protection material makes additionally to hold.

(2) Raw material processing technology and equipment are basically the same. Dongguan paper pallet factory tells you that if waste paper raw material is used to produce paperboard, waste paper sorting, water pulp shredding, pulp beater or grinder grinding, pulp sizing. Mixing and other processes, and then pump to the paper machine for sheet forming, pressing dehydration, drying cylinder driving process into the paper finished products. The paper pulp molding production uses wheat straw pulp or waste paper raw materials, but also through the hydraulic pulp shredder, beater or grinder grinding pulp, pulp sizing, blending and other processes, and then transported to the paper molding machine for molding, extrusion dehydration, drying and shaping, to become qualified paper pulp molding finished products. The raw material handling equipment in the two production processes can even be used in the same way, except for the molding and drying equipment.

(3) the forming principle is similar, but the form of the finished product is different. Dongguan paper pallet factory tells you that pulp molding production and paper and board production are formed by wet forming method, and then dehydration, drying into finished products. The difference between the production process of pulp molding and the traditional paper production process lies in that the paper or cardboard is "sprayed" or "scooped" in the wet section of the paper making machine on the forming net (metal net or plastic net) on the dehydration forming, the wet paper pages and dry finished products are continuous flat strip, and rolled into the form of a drum.

Paper making and production of paper holder difference: forming drying equipment is different. Huimusen paper support factory tells you that paper or cardboard copying machine is generally relatively large, forming and drying into one of the equipment.
