Exterior Insulation Board Microwave Drying
▪ Easy to control: Easy to operate and flexible, automatic control of heating time and drying temperature, saving time, less energy con- sumption, production intensity, equipment covers a small area.
▪ Save time and effort: especially easy and before and after the pro- cess into automatic production line, reduce the number of handling, environmental protection, sanitation, no pollution, but will not produce "three waste problem".
▪ Drying fast: high efficiency, good product color, according to comp- arison, microwave drying speed than commonly used convection drying speed 20 to 30 times faster.
▪ Uniform drying: Microwave drying can make the material inside and outside at the same time, dry evenly and thoroughly, the surface will not be stiff, high toughness, to ensure that will not crack, deformation, discoloration, correction of bending degree, etc..
▪ High efficiency and energy saving: Far infrared and steam drying materials, energy utilization rate is less than 50%, while microwave can reach more than 75%, energy consumption is reduced more than 25%, perlite insulation board microwave drying only 10-20 minutes.
▪ Scope of application: perlite, fiberboard, decorative board, gypsum board, rock wool insulation board, etc.
Principle of Microwave Sterilization Drying
Microwave sterilization is the result of the combination of thermal and biological effects of electromagnetic fields. The thermal effect of microwaves to bacteria is to make proteins change, causing bacteria to lose nutrients, reproduce and survive conditions. The biological effect of microwave on the bacteria is microwave electric field change in the cross section of the cell membrane potential distribution, influence the membrane surrounding electrons and ions concentration, which change the membrane performance, fully bacteria so malnutrition, cannot normal metabolism, cell structure function disorder, growth is restrained and death. In addition, the microwave can make normal bacteria growth and stable genetic breeding of nucleic acid RNA and DNA, DNA is made up of a number of hydrogen bonding is flabby, faults and restructuring, and thus induce genetic mutations, or chromosome aberration and even rupture.
