Paper plays a key role in our daily life and papers have been used for many years from now. Papers are made with the pulp of the woods, which is an Eco-friendly product. Pulp and paper are made from cellulosic fibers and other plant materials.

Pulp and Paper Manufacturing Process in the paper industry

Pulp is a lignocellulosic fibrous material prepared by chemically or mechanically separating cellulose fibers from wood , fiber crops , waste paper , or rags. Mixed with water and other chemical or plant-based additives, pulp is the major raw material used in papermaking and the industrial production of other paper products. Before the widely-acknowledged invention of papermaking by Cai Lun in China around AD, paper-like writing materials such as papyrus and amate were produced by ancient civilizations using plant materials which were largely unprocessed. Strips of bark or bast material were woven together, beaten into rough sheets, dried, and polished by hand. In addition to mulberry, pulp was also made from bamboo, hibiscus bark, blue sandalwood, straw, and cotton.

Paper and pulp processing and additive chemicals are an integral part of the total papermaking process from pulp slurry, through sheet formation, to effluent disposal. Environmental concerns, increased use of recycled waste paper as a replacement for virgin pulp, changes in bleaching and pulping processes, increased efficiency requirements for the papermaking process, limits on effluent discharge as well as international competitiveness have greatly impacted the paper and pulp chemical additive market. This book features in-depth and thorough coverage of Chemical additives in Pulp and Paper Industry. Pratima Bajpai is currently working as a Consultant in the field of Paper and Pulp.

2.1 Introduction Brief Description of the Pulp and Paper Making Process

Pulp and paper mills are highly complex and integrate many different process areas including wood preparation, pulping, chemical recovery, bleaching, and papermaking to convert wood to the final product. Processing options and the type of wood processed are often determined by the final product. The pulp for papermaking may be produced from virgin fibre by chemical or mechanical means or may be produced by the repulping of paper for recycling.

Description

Она кивнула. - Потеряла билет. Они не хотят и слышать о том, чтобы посадить меня в самолет. На авиалиниях работают одни бездушные бюрократы. У меня нет денег на новый билет. - Где твои родители? - спросил Беккер.

Aeropuerto, - заикаясь сказал Двухцветный. - Aeropuerto? - повторил человек, внимательно следя за движением губ Двухцветного в зеркале. - Панк кивнул. - Tenia el anillo. Он получил кольцо.

Послание ничем не отличалось от многих других, которые он получал: правительственное учреждение просит его поработать переводчиком в течение нескольких часов сегодня утром. Странным показалось только одно: об этой организации Беккер никогда прежде не слышал. Беккер позвонил одному из своих коллег: - Тебе что-нибудь известно об Агентстве национальной безопасности. Это был не первый его звонок, но ответ оставался неизменным: - Ты имеешь в виду Совет национальной безопасности. Беккер еще раз просмотрел сообщение.
