Effect of pigment dispersion on coating properties

This is a measure of the characteristics of the film, the higher the gloss, the stronger the reflection. For coating luster, particles can not be greater than 5 microns, 3 microns.Ink can not exceed 1 micron.Large particles in coatings are either inefficiently dispersed, flocculate, or stimulate crystallization during preparation.Polymer dispersants also reduce the formation of large particles due to flocculation and improve gloss. transparent This is a property of the film, the higher the transparency, the easier it is to see the [...]

Application of Intelligent Drying Time Recorder in Coating Industry

Application of Intelligent Drying Time Recorder in Coating Industry The intelligent drying time recorder is used to measure the drying time of wet film such as paint, ink and glue.The drying and curing of wet film is a slow and continuous process. In order to observe each stage of drying conveniently, an intelligent drying time recorder with certain control conditions is needed to measure.The intelligent drying time recorder uses a needle to cross the coating at a constant speed and [...]

How to calculate the compressive strength of cartons?

Cartons are required to have a certain compressive strength, because after packing goods in the process of storage and transportation, the cartons stacked in the lower layer are under the pressure of the upper cartons. In order to avoid collapse, they must have appropriate compressive strength. The compressive strength of cartons is calculated by the following formula: P = KW (n – 1) In the formula, ص—- carton compressive strength, N W—- Carton weight after loading, N N —- Number of stacking layers K—- [...]
