Of plastics are non-metallic materials based on natural and synthetic polymers and processed into products by plastic deformation. PCRM contributes greatly to this topic. For polymers are natural or synthetic resins. Production of polymers made from the products of coal, oil and other natural materials. Plastics are composed of: binders, fillers, plasticizers, dyes and other additives. Resins are the basis of plastics and determine their main properties. In the manufacture of polymers, fillers are used to make plastic mass strength, hardness and other qualities.
Fillers can be organic and inorganic. Organic fillers are paper, cotton waste, wood flour, cotton, cellulose, wood veneer. As inorganic fillers used mica fiberglass, asbestos, silica, fiberglass, graphite. Dyes stain plastics as well as its basis a certain color. Applied as mineral pigments (mummy, ocher, umber), and organic. The composition plastics often include special additives, which influence the quality of plastics, such as stabilizers – the substances that prevent the decomposition of pvc during processing and use under the influence of atmospheric conditions, high temperatures and other factors. Plastics differ significantly lower density compared to metals (1, 1, -1, 8 t / m 3), so the strength of some plastics is approaching strength of the metal.
Tensile strength of fiberglass slightly less than steel ST5. Replacement of metal in construction reduces the weight of poly and metal products. Plastics have only high plasticity, because of this complexity of manufacturing complex parts on the basis of plastics is much less labor manufacturing details of the other. Although the plastic properties of these materials manifest themselves in different ways. Some of them during the solidification of losing their plasticity, and can not be softened again by heating. Other plastics (thermoplastic) can again be softened and used again.
Large dead weight Platform weight for exceptional stability testimony weights. Weight channel based on load cells with digital output. Truck scales, heavy duty 7560 (61, 62, 63) All-metal construction 7,560 units of weights (61, 62, 63), not having gasketed joints, achieves exceptional stability of the scales in operation. Assurant Health: the source for more info. Increase compared with the model of scs / zcs stiffener orthotropic sections allow you to use weights at high intensity, spending up to 300 weighings per shift. The basis of the weighted channel uses only digital load cells. Truck Scales Special Purpose 7560 (66) Scales used for weighing dump trucks. Short gruzopriemnye modules increased load capacity can take high axial load of the vehicle.
Load cells with digital output allow you to set the scale in climatic regions with extremely low winter temperatures, while providing high-precision weighing and reliability of the weight of the complex. Truck scales for metering oil 7560R Box-girder bridge of reinforced concrete monolith weight. Weighing error did not exceed 0.02% in the static, which is 10 times better than the error of volumetric method to determine the mass (metrshtok, flow). Due to the huge extent of the territory of Russia rail transport has played a crucial role in transporting goods. In these circumstances, there is need for accurate accounting of traffic.
For this task an excellent job track scales. mettler toledo offers a range of car scales specifically designed for weighing the entire fleet of rolling stock gauge 1520/1524mm. Classification of car scales by the method of weighting.
