01. A kind of waterproof engineering thermal insulation mortar, which is characterized by the following raw materials by net weight: concrete 300-340, engineering construction waste brick powder 40-50, lignin fiber 20-24, calcium formate 4-6, hydroxyl Propyl methyl cellulose 7-9, silicon carbide micropowder 40-45, calcium hydroxide powder 10-20, brown corundum powder 10-12, dry city sludge powder 30-35, Datong city soil 40-45, sulfuric acid Aluminum 4-6, carboxymethyl starch 20-24, modified material nanotechnology carbon powder 4-6, water 600-650; this product waterproof engineering insulation mortar has strong heat insulation, good fire resistance, and is bonded to the wall Strong, compressive strength, tensile performance, good aging resistance, good environmental protection, excellent moisture resistance, crack resistance, and drop resistance.
02. What is the viscosity of hydroxypropyl methylcellulose aqueous solution?
1. The relative molecular mass of cellulose ether, the temperature of the aqueous solution, the cutting rate, and the experimental method;
2. The higher the glass transition temperature, the greater its relative molecular mass, and the higher the viscosity of the solution;
3. The higher the content of cellulose ether, the higher the viscosity of the solution. Therefore, we should pay attention to the appropriate amount of mixing in the application to prevent the mixing amount from being too high, which will directly affect the cement mortar and cement concrete. characteristic;
4. Like most solutions, the viscosity will decrease with the increase of temperature, and the higher the content of cellulose ether, the greater the damage of its temperature; in addition, the actual thickening The effect also varies according to the water consumption of the epoxy cement material.
