Hydroxypropyl methylcellulose and cement ratio

HPMC and cement ratio

01
A waterproof engineering thermal insulation mortar, which is characterized by being made of the following raw materials by net weight: concrete 300-340, engineering and construction waste brick powder 40-50, lignin fiber 20-24, calcium formate 4-6, hydroxypropyl Methyl cellulose 7-9, silicon carbide micropowder 40-45, calcium hydroxide powder 10-20, brown corundum powder 10-12, dry big city silt powder 30-35, Datong soil 40-45, aluminum sulfate 4 -6, carboxymethyl starch 20-24, modified material nanotechnology carbon powder 4-6, water 600-650; this product waterproof engineering thermal insulation mortar has strong heat insulation, good fire resistance, and strong adhesion to the wall. Compressive strength, tensile performance, good aging resistance, good environmental protection, excellent moisture resistance, crack resistance, and anti-dropping properties.

Today, 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 higher the relative molecular mass, and the higher the viscosity of the solution;

3. The higher the content of cellulose ether, the higher the viscosity of its solution. Therefore, we should pay attention to the appropriate dosage when implementing the application to prevent the dosage from being too high, which will directly affect the cement mortar and cement concrete. characteristic;

4. Like most solutions, the viscosity will also decrease with the increase of temperature. In addition, the higher the content of cellulose ether, the greater the harm to the temperature; in addition, the actual thickening The effect also varies according to the water consumption of the epoxy cement material.
