The progress of vacuum dryer technology will reverse the current domestic export situation of drying equipment. China's vacuum dryer equipment export volume is less than 5% of the total, the export market scale has not yet been shaped, has been mainly exported to Southeast Asia.

In domestic dryer technology today, the drying process requires large amounts of thermal energy. In order to save energy, some high moisture content materials, suspensions or solutions containing solid materials are generally first mechanically dehydrated or heated to vaporize, and then dried in a desiccator. To get a dry solid. Here, Changzhou vacuum dryer manufacturers told everyone about the working principle of the vacuum dryer: During the drying process, the heat and mass (moisture content) transfer must be completed at the same time to ensure that the moisture partial pressure (concentration) of the surface moisture of the material is higher than the external. The moisture partial pressure of steam in the space ensures that the temperature of the heat source is higher than the temperature of the material.

The heat is transferred from the high temperature heat source to the wet material in various ways, vaporizes the surface of the material and disperses into the external space, so that the difference in moisture content occurs on the surface and inside of the material. The internal moisture spreads to the surface and vaporizes, so that the moisture content of the material is continuously reduced, and the overall drying of the material is gradually completed.

It is predicted that with the development of technology, the proportion of China's export vacuum dryer equipment in total output will increase from 5% to 10% in the next few years, and the export market will also expand to Europe and the United States. Gradually shorten the gap between the domestic large-scale vacuum dryer equipment manufacturing and the international level.

Disperse Dyes Printing Thickener


A brief introduction to the additives:
Disperse dye Printing Thickener as the main additive in the chemical printing industry, because of its excellent thickening, has already appeared in people's field of vision early, its true face is a rheological additive, can be no exaggeration It is said that it only needs to add a small amount of thickener to make it play a big role. Is its advantage only reflected in this amount? No, let me introduce you to the specific advantages of disperse dye printing thickeners.
Advantages of additives:
1. After the consistency of the raw liquid product is increased, the raw liquid is better penetrated into the textile and uniformly sizing.
2. Provide good rheological properties for dyes or pigments, so that they are evenly distributed during printing without splashing and sagging.
3. Better penetration of the dye into the textile, combined with the fibers to form a well-defined, well-defined textile print.
4. The consistency is increased, so that the dye in the printing is fixed, and the reaction product and the residue are more conveniently and easily washed away.
Auxiliary application system:
Disperse dye printing thickeners are widely used in the thickening of textile printing and dyeing, coatings, printing and dyeing, sanding cloth, cotton cloth, chemical fiber cloth and other systems.
