Method for manufacturing and shaping environment-conservative plant fiber as substitute for wood, paper, and plastics

Abstract

Disclosed is a method for manufacturing environment-conservative plant fiber as substitute for wood, paper, and plastics, which includes the steps of having agricultural surpluses and/or plant wastes ground and then mixed with starch, a plasticizer, and additives according to desired percentages by using a high speed mixing machine, deposited into a dual screw machine for pressurization and blending, pulverized by a pulverization machine, processed by an extrusion machine, subjected to temperature control by using a mold temperature controller, and then deposited in a cooling system for cooling and pelletization by airstreams to complete workable environment-conservative plant fiber particles. The particles can be used to substitute wood, paper, and plastics for making various products. The manufacturing process of the method releases completely no waste water and waste gas. The products made of the particles are completely recyclable for re-use. Environmental conservation and reduction of energy consumption can be realized.

1 . A method for manufacturing environment-conservative plant fiber as substitute for wood, paper, and plastics, comprising processing a raw material that is formed of powders of agricultural surpluses and/or plant wastes added with starch and additives, wherein the agricultural surpluses and/or plant wastes take a percentage of 63-73%, the starch takes a percentage of 15%-20%, and the additives take a percentage of 5%40%, a plasticizer being further added in a percentage of 7%, the method comprising the steps of the agricultural surpluses and/or plant wastes being ground and then mixed with the starch, the plasticizer, and the additives according to desired percentages by using a high speed mixing machine, deposited into a dual screw machine for pressurization and blending, pulverized by a pulverization machine, processed by an extrusion machine, subjected to temperature control by using a mold temperature controller to a temperature within the range of 160-180° C., and then deposited in a cooling system for cooling and pelletization by airstreams to complete workable environment-conservative plant fiber particles. 
     
     
         2 . The method according to  claim 1 , wherein the agricultural surpluses and/or plant wastes are ground to 60-100 mesh, and are then directly subjected to extrusion by an extruding machine to make lumbers, angles, and boards. 
     
     
         3 . The method according to  claim 1 , wherein the agricultural surpluses and/or plant wastes are ground to 100-150 mesh, and are then directly subjected to injection molding by an injection molding machine to make plastic substitute products. 
     
     
         4 . The method according to  claim 1 , wherein the agricultural surpluses and/or plant wastes are ground to 150-200 mesh, and are then used to make paper boards, cartons, and paper cases or are processed by a vacuum molding machine to form packages boxes for internal and external uses.
