水玻璃测试性能及测试方法一览表
水玻璃, 也称为硅酸钠溶液, is a colorless transparent inorganic substance composed of sodium silicate and water. Water glass absorbs moisture easily in dry air and forms a solid, which can be used in a variety of industrial and everyday applications. It has excellent properties such as water resistance, 耐酸碱, and permeability resistance. It is widely used in construction, waterproofing, 粘合, mineral impregnation and other fields. 同时, water glass can also be used in the production of fertilizer, fireproof materials, pulp and ceramics.

检测方法
The following is a brief description of the test method for the common performance parameters of water glass:
固含量: The water glass sample is heated to about 105℃, dried to constant weight, and the ratio of the mass of non-volatile substances to the total sample mass is calculated.
相对密度: the water glass solution is added to the density meter, the density of the solution is measured, and the relative density is calculated.
PH值: Use PH meter and other equipment to measure the pH of water glass solution, evaluate its stability and application effect.
粘度: The use of viscometers and other equipment to measure the viscosity of water glass solution has an important impact on the application of specific applications, 比如涂层, impregnation, ETC.
Permeability resistance: Use gas permeability meter, water immersion tester and other equipment to assess the water and gas penetration resistance of the water glass coated or impregnated substrate.
Water retention: The use of weighing method and other equipment to measure the water absorption of water glass coating or impregnated substrate, reflecting the water retention performance of the coating or impregnated.
Sulfate content: Use spectrophotometer and other equipment to measure the content of sulfate in water glass solution.
Chloride content: Use devices such as chloride ion selective electrodes to measure the chloride content in water glass solution.
The North and South tide reminds you: 不同的性能参数可能需要不同的测试方法和设备, 并且可能有一些行业标准和规范, for the performance of water glass testing, should also be selected according to the actual needs of the corresponding detection methods and standards. 同时, it is necessary to strictly control the test conditions and standardized operations during the experiment to ensure the accuracy and reliability of the test.
