Sawdust-reinforced pulp material and method of producing the same

Abstract

A sawdust-reinforced pulp material and its preparation method are herein disclosed Specifically, the method for preparing the sawdust-reinforced pulp material comprises the steps of: mixing 70% to 85% by weight of a pulp prepared from waste paper with 15% to 30% by weight of sawdust, based on the total weight of pulp and sawdust, to prepare a mixture of pulp and sawdust; blending the mixture with an adhesive in the weight ratio of 1:1; pouring the mixture blended with the adhesive into a mold to form a pulp material; and naturally drying the formed pulp material at an ambient temperature of 20 to 25 degrees C to produce the sawdust-reinforced pulp material.

1 . A method of producing a sawdust-reinforced pulp material, the method comprising the steps of:
 mixing 70% to 85% by weight of a pulp prepared from waste paper with 15% to 30% by weight of sawdust, based on the total weight of pulp and sawdust, to prepare a mixture of the pulp and the sawdust;   blending the mixture with an adhesive in the weight ratio of 1:1;   pouring the mixture blended with the adhesive into a mold to form a pulp material; and   naturally drying the formed pulp material at an ambient temperature of 20 to 25 degrees C. to produce the sawdust-reinforced pulp material.   
   
   
       2 . The method of  claim 1 , wherein the adhesive is a mixture of 80% to 90% by weight of water with 10% to 20% by weight of an environmentally friendly adhesive. 
   
   
       3 . A method of producing a sawdust-reinforced pulp material, the method comprising the steps of:
 mixing 60% to 70% by weight of a pulp prepared from waste paper, 15% to 20% by weight of sawdust and 5% to 10% by weight of an additive, based on the total weight of pulp, sawdust and additive, to prepare a mixture of the pulp, the sawdust and the additive;
 blending the mixture with an adhesive in the weight ratio of 1:1; 
 pouring the mixture blended with the adhesive into a mold to form a pulp material; and 
 naturally drying the formed pulp material at an ambient temperature of 20 to 25 degrees C. to produce the sawdust-reinforced pulp material. 
   
   
   
       4 . The method of  claim 3 , wherein the additive is a mixture of 30% to 50% by weight of charcoal powder, 20% to 25% by weight of yellow ocher powder, 15% to 20% by weight of glass fiber, 10% to 15% by weight of ceramic powder and 5% to 10% by weight of silver powder. 
   
   
       5 . An apparatus for preparing a sawdust-reinforced pulp material comprising:
 a means for mixing 70% to 85% by weight of a pulp prepared from waste paper with 15% to 30% by weight of sawdust, based on the total weight of pulp and sawdust, to prepare a mixture of the pulp and the sawdust;   a means for blending the mixture with an adhesive in the weight ratio of 1:1;   a means for pouring the mixture blended with the adhesive into a mold to form a pulp material; and   a means for naturally drying the formed pulp material at an ambient temperature of 20 to 25 degrees C. to produce the sawdust-reinforced pulp material.   
   
   
       6 . An apparatus of  claim 5  further comprising: a means for mixing 60% to 70% by weight of a pulp prepared from waste paper, 15% to 20% by weight of sawdust and 5% to 10% by weight of an additive, based on the total weight of pulp, sawdust. and additive, to prepare a mixture of the pulp, the sawdust and the additive.
