As an important industrial raw material, wax emulsions are widely used in papermaking, textiles, leather, coatings, adhesives and other industries. In order to ensure the stability and performance of wax emulsions in different applications, their quality must be strictly controlled and systematically tested. This article will discuss the key points of quality control of wax emulsions and the main detection methods.
In the process of producing wax emulsions, quality control involves many aspects, mainly including the following points:
High-quality wax emulsions are inseparable from high-quality wax raw materials, such as polyethylene wax, carnauba wax, microcrystalline wax, etc. In addition, the selection of emulsifiers is equally important. Suitable emulsifiers can improve the stability of wax emulsions.
The stability of wax emulsions depends on the emulsification process, including factors such as temperature control, stirring speed, emulsifier concentration and emulsification time. Accurate control of these parameters can ensure the uniformity of the emulsion.
Wax emulsions should maintain appropriate temperature and humidity during storage and transportation, and avoid long-term exposure to high or low temperature environments to prevent emulsion stratification or agglomeration.
In order to ensure that the quality of wax emulsions meets industry standards, multiple tests are required. The following are several common detection methods:
Particle size is an important indicator that affects the performance of wax emulsions. Laser particle size analyzers are usually used to measure the distribution of wax particles. The ideal particle size range can improve the uniformity and stability of the emulsion.
Solid content determines the concentration of wax emulsions, which can be determined by drying (constant temperature oven), that is, the dry mass of the sample is calculated after drying at a certain temperature.
The stability of pH directly affects the chemical properties of wax emulsions. Usually a pH meter is used for measurement to ensure that the pH value of the emulsion meets the application requirements.
Viscosity affects the construction performance of wax emulsions and can be tested by a rotational viscometer or rheometer to evaluate its fluidity and application adaptability.
The storage stability of wax emulsion is evaluated by simulating the stratification under long-term storage conditions in a high-speed centrifuge.
The wax emulsion is heated to a certain temperature and observed to see whether phase separation or precipitation occurs to evaluate its high temperature resistance.
Strict quality control and testing can ensure the reliability of wax emulsion in various application scenarios and improve customer satisfaction. In addition, high-quality wax emulsion can effectively improve the performance of end products, such as enhancing the water resistance of paper, improving the softness of textiles, and enhancing the wear resistance of coatings.
