Mechanical pulp of wheat straw and bagasse was obtained by using technology of twisting up and high concentration refining.The product can partly replace the chemical pulp for wall decoration.The effect of addition of the mechanical pulp on appearance,stiffness,tensile,thermal insulation were investigated.It is shown that upon the increase of the addition of the mechanical pulp,the stiffness increases at first and then tends to decrease.It reaches peak to the increment to 9.36% and 8.62% at the addition of ...
