Vertical Liquid Ring Water Circulating Vacuum Pump for Laboratory

Product Description:
Â Â The Vertical Liquid Ring Water Circulating Vacuum Pump is a cutting-edge vacuum pump designed with circulating water as its working fluid. It utilizes jet technology to create negative pressure, making it ideal for both vacuum suction and cooling applications in laboratory settings. This model offers a non-oil, pollution-free operation, excellent corrosion resistance, low noise levels, and ease of mobility.
It provides essential vacuum conditions for various experiments such as evaporation, distillation, crystallization, drying, filtration under pressure, and vacuum degassing. It is widely used in academic institutions, research centers, chemical industries, pharmaceuticals, biochemistry, food processing, pesticides, agricultural engineering, and biotechnology sectors.

Dyeing Auxiliaries For Polyester
In textile dyeing, it is hoped that the dyes can be evenly dyed on the fabric, without uneven depth and color spots, and has a good covering ability for the difference of affinity caused by the quality of the fiber. For this reason, the general selection of appropriate levelling agent is important. Polyester is one of the three major synthetic fibers with the fastest developing speed. It has good wear-ability and is the main fabric used for outerwear. When polyester and its blended fabrics are dyed with disperse dyes at high temperature and high pressure, the temperature rise rate will be improperly controlled due to the poor dispersion and evenness of the dyes. Therefore, effective levelling agent must be added when dyeing. Because the dyeing temperature of polyester fabric is generally around 130â„ƒ, that means this kind of dyeing agent is used to called high temperature leveling agent.
