The ASTM E1839-20 standard, developed by the American Society for Testing and Materials (ASTM), describes a test method for evaluating the effectiveness of slimicides for the control of bacteria and fungi in paper mill systems and their equivalents. It is the research assistant's responsibility to determine if Good Laboratory Practices (GLP) are required and to follow them where appropriate.
This test method is used to determine whether a slime control agent has an application in the paper industry for bacterial or fungal slime / biofilm control. This test method is carried out in acid, alkali or acid and alkaline conditions to determine the effectiveness of the slime control agent. Test conditions can be modified to reflect intended use patterns in typical paper mill systems, including the use of real mill equipment.
Slimicide, slime like algae, bacteria, fungi and slime molds It is a broad-spectrum antimicrobial pesticide used to kill microorganisms that produce bacteria.
Methods of controlling microbiological problems include controlling sources of contamination and controlling microbiological populations. Treatment of fresh water and additives, control of residence time in storage tanks and control of stagnant flow areas should be done to control pollution sources and microbiological populations. It is necessary to use different chemicals to reduce the formation of sediment and to eliminate the formed deposits. When sources of contamination are reduced, the paper manufacturer can control the microbiological populations of the system. Good cleaning and regular inspection of all areas reduce the formation of slime. In paper machines, chemical products are introduced into the system to prevent the growth of microorganisms and to eliminate the harmful effects they produce. The most commonly used chemical products are dispersants and biocides. Other control methods are to limit the enzymatic degradation of microbiological residues. It is not possible for the paper industry to continue its activities without the use of chemicals to control slime formation.
Our organization also provides standard bacterial and fungal slime testing services for slimicides activity in the paper industry within the scope of ASTM E1839-20 standard, with its trained and expert staff and advanced technological equipment, among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors.
