On the premises of the TECHNO plant in Ryazan, there is an organized quality control department with its own certified laboratory The departmental specialists maintain strict quality controls on the output products, according to a four-stage system that includes the following steps: incoming inspections of the raw material components, quality control of the semi-finished products on the line and directly at the stage of the substrate cutting, and control of the products as they leave the conveyor Special attention is paid to the performance and testing results of the final product The last step is the selective control of the products in warehouse storage conditions.
The primary quality indicators, such as the appearance, geometrical dimensions, holes, groove cutting, density, immersion in water, and reli- ability of the weld joints, are determined by the production personnel directly on the line.
In the laboratory, multiple tests and inspections of the semi-finished and samples of the finished product are conducted, which guarantee the continuous improvement and stability of the substrate quality characteristics that affect the plant growth.
The following product indicators are tested in accordance with the technical specifications: compressive strength at 10% deformation, water absorption, shrinkage at full wetting, and porosity In addition to the basic control activities, the laboratory specialists carry out checks of the pH value, block water retention / water loss, this bio-testing for cress growth.
Thanks to this testing and the step-by-step controls, our clients always receive high quality substrates with stable performance characteristics.
