Chemical paste vacuum microwave drying is a drying method that combines the advantages of vacuum and microwave technologies to dry chemical pastes. Chemical paste vacuum microwave drying is widely used in the chemical industry. For example, in the production process of some resins, pastes containing solvents need to be dried to remove solvents and improve product quality. In addition, for some chemical pastes with heat - sensitive components, such as certain pharmaceutical intermediates and special coatings, this drying method can also effectively retain their active components and performance.
