Manufacture of Low Temperature Type Heat Insulation Paper Based on In-situ Synthesis of Magnesium Aluminum Silicate
摘要
Abstract
The feasibility and process conditions of heat insulation paper manufacture based on in-situ synthesis of magnesium aluminum silicate in the hard wood pulp fibers were investigated. The results indicated that the better process conditions for manufacture of magnesium aluminum silicate heat insulation paper as the follows; the concentration of sodium silicate was 0. 5 mol/L, the volume ratio of alumina sulfate (23 mol/L) and magnesium sulfate (1 mol/L) solution was 4:6, the reaction time and temperature was 30 min and 70℃ respectively. Compared with the base paper, coefficient of heat conductivity of the paper reduced by 38. 55% , and the brightness increased by 32% , however, the strength was lower than base paper. The synthetic material, microstructure and properties of the heat insulation paper were observed by SEM-EDAX. The results showed that the manufacture condition was easy to fulfill; the magnesium aluminum silicate was deposited on the fibers surface and in the fiber cells.关键词
