Analysis of the cause of the film on the resin cutting piece
During the use of daily life, many consumers will soften when cutting materials, especially aluminum flat cutting disc. Many people can't figure out what to do. The following is a summary for the majority of consumers, to answer questions. The solution of the large-section film is a technical problem, which is also caused by the influence of comprehensive factors. It mainly involves factors such as process plan, technical route, formula, consistency of raw materials and process. 1. The hardening temperature is low, or the temperature is too high, and the temperature and humidity suddenly change greatly. In addition, the fluctuation of the relevant technical indexes of the raw materials simultaneously meets the requirements of the Huaji cutting wheel film. If the hardening curve is the same as before, The film will be produced. The low stability of hardening means that the highest i-hardening temperature of the high quality cutting disc supplier be provided in time due to the double influence of the environment and raw materials, when the seasons alternate or the temperature and humidity change significantly. The hardening is high, which means that the hardening curve has been adjusted, but when the stability is reduced, the weather is dry and the hardening is not lowered in time, which is also easy to cause the grinding wheel film. 2. A short time of hardening curve This mainly means that under certain conditions, the low-temperature drying time of the hardening curve is short, and the heating rate is too fast in the heating stage. 3, the furnace or the kiln is too urgent or the temperature difference is too large. Because the grinding wheel, especially the grinding wheel with large diameter, should have a certain cooling period at the end of the hardening and heat preservation to meet the uniform release of the stress of the resin cutting wheel; at this time, if the temperature is too high Or if the temperature difference changes too much, the cooling changes of the grinding wheel will not be synchronized, so the deformation of the grinding wheel will appear. The resin-cut grinding wheel film is actually a form of deformation. 4. Elimination of hardened humid atmosphere in hardened furnaces All hardening furnaces, whether box furnaces or tunnel kiln, must consider intake and exhaust when designing furnaces. Due to the release of a large amount of exhaust gas (mainly ammonia gas and water vapor) during the hardening of the resin grinding wheel, if these exhaust gases cannot be discharged in time, they will be re-absorbed by the pores of the resin grinding wheel during the cooling process of the grinding wheel, thus causing the grinding wheel to smell. And soft.
