19 Apr Pulp Production
Pulp is usually produced from wood cellulose, i.e. tree fibres. However pulp production Many different materials can be used, for example, alternative sources such as natural materials such as waste paper, straw, flax, bamboo and rice husk can also be used. In this article, we will give detailed information about pulp production.
Chemicals used in its production include substances such as soda ash, sulfate mixtures and hydrogen peroxide. These chemicals help improve the quality and durability of paper by changing the properties of the pulp.
Alternative sources can also be used. The use of materials such as waste paper, straw, bamboo and rice husk can help preserve natural resources and reduce environmental impacts.
What is the Pulp Production Process?
Raw Material Preparation: Raw material is generally wood cellulose, bark and wood residues. This raw material is first milled to the correct dimensions. It is then mixed with water to release the fibers in the water.
Scalding: pulp production The mixture prepared for the mixture is then transferred to a large boiler and chemical additives are added. These additives help loosen and separate the fibers. The type of chemicals used during the scalding process may vary depending on the raw material used and the type of paper.
Sifting: After the scalding process is completed, the mixture is passed through a sieve. This allows waste and large pieces to be separated.
Polishing: The mixture is then transferred into a polishing drum. This drum helps compress and dehydrate the mixture.
Drying: The mixture is dried in a drying cylinder and then flattened. This process helps the paper reach its final state.
Cutting: Paper is sold in rolls or cut and then offered for sale.
Chemical Substances Used in Paper Pulp Production
Soda ash helps break down wood cellulose and helps whiten the pulp. Sulphate blends are used to separate wood cellulose and help produce higher quality papers. Hydrogen peroxide is an oxidizing agent that helps whiten the pulp and improve its quality.
Machines Used in Pulp Production
pulp production Machinery and equipment used for:
Wood pulp preparation machines: Used for grinding, chopping and shredding wood.
Scalding boilers: Used to process wood pulp with chemical mixtures.
Sieves: Enables the separation of the mixture from waste and large pieces.
Polishing drums: Helps compress the mixture and remove its water.
Drying rollers: Used for drying and flattening paper pulp.
Cutting machines: Used to determine the size and shape of the paper.
It is an industry where paper is the main material. This process includes the steps of raw material preparation, sizing, sieving, polishing, drying and cutting. Although pulp production has significant impacts on the environment, environmental impacts can be reduced through the use of alternative resources.
