[Abstract]:Aiming at the shortcomings of the existing glass bead insulation board, such as poor thermal insulation performance, high dry density and low strength, the performance testing method of the thermal insulation board is established from the aspects of raw material selection, proportion optimization and so on. Orthogonal test was used to study the proportion of insulation board. Through the analysis of extreme difference and variance, the initial proportion was obtained, and the optimum ratio was obtained by optimizing the ratio test and considering the comprehensive performance of the insulation board. The main research contents are as follows: 1. By comparing and analyzing the advantages and disadvantages of the existing glass bead insulation board, the experimental raw materials are selected. At the same time, by comparing and analyzing the current relevant test standards, the performance test standards of vitrified microbead insulation board are determined. Based on the basic ratio of ordinary glass microbead insulation mortar, three indexes of dry density, compressive strength and consistency are considered. According to the test, the proper packing density and water consumption of the glass beads were determined. Through the analysis of the existing relevant specifications of the glass beads, the test proportioning assessment index was established, and the four factors and three levels orthogonal test was adopted. The dry density, thermal conductivity and compressive strength of the thermal insulation board were taken as the evaluation indexes. The content of glass microbeads and cement was studied by means of extreme difference and variance analysis. The influence of fiber brucite content and compound admixture on the three indexes. The main and secondary factors affecting the performance of the thermal insulation board and its significance were obtained, and the experimental ratio of the glass microbead insulation board was preliminarily determined. On this basis, the test ratio was further optimized, and the bending strength and linear shrinkage of the thermal insulation board were considered. On the premise of meeting the test ratio and testing index and surpassing the existing performance of inorganic fire insulation board such as perlite. Determine the best proportion of heat preservation board. 3. Apply glass microbead insulation board to common wall, through thermal calculation. The minimum thickness of vitrified microbead insulation board is obtained to meet the energy saving requirements of 65% in North China. The specifications and dimensions of expanded glass bead thermal insulation board are formulated with reference to the engineering technical specification of perlite thermal insulation board. The basic structure of exterior wall thermal insulation system is designed, and the construction method of thermal insulation board is put forward.
