The beating is a preliminary step in testing the physical properties of pulp. The beating of the pulp process helps to achieve the desired quality of the paper.
BS 6094-1 specifies a method, using a Valley beater, for the laboratory beating of pulp. The description is limited to the furnishing and beating of the stock, the withdrawal and distribution of samples, and the beating equipment. A measured amount of pulp of specified stock concentration is beaten between the bars of the roll and the bedplate of a Valley beater. Samples of beaten pulp are taken at intervals during the beating.
BS 6094-1 is applicable to all kinds of pulp. BS 6094-2 specifies a method of laboratory beating using a PFI mill and BS 6094-3 specifies a method using a Jokro mill.
BS 6094-1 on pulp beating in paper making process is useful for:
The beating of pulps is probably the most fundamentally important process in papermaking. The purpose of pulps beating is to increase the strength of the produced paper.
BS 6094-1 provides you with methods for laboratory beating of pulps using the valley beater method. The aim of standardization of laboratory beating is to develop a pulp test method which is internationally acceptable, and which allows the energy consumption during beating to be measured.
BS 6094-1 guides you with methods of preparing pulp extracts for sampling, beating procedure, and test results expression. BS 6094-1 also provides you guidance on the use of equipment in order to achieve consistency of results with each instrument.
Following the guidelines provided in BS 6094-1 helps you to improve the strength of the paper and you will be able to achieve the desired quality of the paper.
