                What is the effect of high strength and wear resistant plastic on the heat preservation of boiler

                Date of release:2019-06-11 Author: Click:

                High strength and wear-resistant plastic can be used to add delay accelerator, which can be used for 1 hour without affecting the demoulding time and strength. At the same time, composite organic superplasticizer and reinforcing agent are added to improve the construction performance of the plastic. At the same time, composite explosion-proof agent and toughening agent are added to improve the oven drying adaptability of the plastic. The plastic can be heated to 350 ℃. The composite micro expandable plastic is selected for the top of the boiler to achieve the expansion and sealing effect at a lower temperature. The micro expandable plastic uses the transformation of quartz crystal phase and the use of compressed fiber ball to achieve the sealing effect. For boiler insulation, comb plate is used to control and reduce hot air convection close to the water wall. At the same time, based on the principle of people-oriented, it is suggested that the outer layer of insulation should be pasted with reinforced aluminum to reduce the harm of heat radiation to people. The igniter is made of high-strength wear-resistant plastic. The igniter is the part of CFB boiler where the temperature is the highest and the quenching and heating are the most serious. Therefore, the material must have small linear shrinkage and high thermal shock stability.
