چکیده
|
Properties of the finished products like paper and board depend on parameters namely cooking liquor concentration, the chemicals and temperature in the digester. in this study digestion of wheat straw is investigated experimentally in sulphite process by varying alkali ratio keeping all other parameters constant. resulting pulp is characterized by a set of properties (percentage yield, consistency, kappa no., sr and ash content). results reveal that the best combination of properties can be achieved at alkali ratio of 10.5 % naoh and 3.5%na2so3.
