Abstract

In this paper, Characterization of different unconventional pulping raw materials was carried out. The studies was done in terms of their contents in ash content, cellulose, ethanol–benzene solubility, , hollocelulose, lignin and hot water and 1% soda solubility was carried out. The use of blending of long fibered pulps with short fibered pulp is an important aspect of paper making .Morphological and Chemical nature of hard and soft wood are in many ways different from each other. Soft wood lack certain factors such as drainage, wet strength and press rolls tendency of sticking. To overcome these issues blending plays an important role. Pulp blending can be done in three distinct ways chips blending, pulp blending before beating and pulp blending after beating. Before pulp beating the properties improves the physical strength marginally. But after beating at 1500 revolutions in a PFI helps to improve the strength properties and resulted in increased pulp yields column.

浆料的替代原料和混配提高浆料的强度

本文对不同的非常规制浆原料进行了表征。对其灰分含量、纤维素含量、乙醇-苯溶解度、全纤维素含量、木质素含量、热水含量和1%纯碱溶解度进行了研究。长纤维纸浆与短纤维纸浆的混炼是造纸的一个重要方面。硬木和软木的形态和化学性质在许多方面是不同的。软木材缺乏一定的因素，如疏水性、湿强度和压辊的粘着倾向。为了克服这些问题，混合起着重要的作用。浆料共混可通过三种不同的方式进行:切片共混、打浆前共混和打浆后共混。浆料打浆前的性能略微提高了浆料的物理强度。但在PFI中经过1500转的打浆有助于提高强度性能，从而提高了纸浆收率。

期刊介绍： International Journal of Management Science and Engineering Management (IJMSEM) is a peer-reviewed quarterly journal that provides an international forum for researchers and practitioners of management science and engineering management. The journal focuses on identifying problems in the field, and using innovative management theories and new management methods to provide solutions. IJMSEM is committed to providing a platform for researchers and practitioners of management science and engineering management to share experiences and communicate ideas. Articles published in IJMSEM contain fresh information and approaches. They provide key information that will contribute to new scientific inquiries and improve competency, efficiency, and productivity in the field. IJMSEM focuses on the following: 1. identifying Management Science problems in engineering; 2. using management theory and methods to solve above problems innovatively and effectively; 3. developing new management theory and method to the newly emerged management issues in engineering; IJMSEM prefers papers with practical background, clear problem description, understandable physical and mathematical model, physical model with practical significance and theoretical framework, operable algorithm and successful practical applications. IJMSEM also takes into account management papers of original contributions in one or several aspects of these elements.
