Material drying

The technology used for the varnish drying has also provided very positive results in the drying of materials such as:

Ceramic manufactured products

The ceramics is a traditional material representing any kind of artificial object, made of inorganic non-metallic materials, molded at room temperature and hardened by heat. The term ‘ceramics’ comprises different products, both hard-paste products like gres or porcelain, and porous-pasta products like majolica and terracotta. The manufactured products can be classified on the basis of their use. Microglass has developed a technology allowing the drying of all types of manufactured products:

  • Traditional ceramics (used in the building industry)
  • Ceramics for coating (tiles)
  • Ceramics for covering (roof-tiles)
  • Ceramics for construction (bricks)
  • Ceramics for sanitary ware

FEATURES

The need to reduce time of drying of ceramic manufactures and of a suitable glaze prompted Microglass to create this system. Combining the well-known advantages of the microwaves that allow the uniform drying of the ceramic bisque (thanks to a homogeneous thermic in-depth profile) to the traditional warming-up method that produces latent energy from evaporation, a new process was created guaranteeing reduction of the processing time and material pressure (therefore avoiding cracks and deformations of the support also with considerably reduced processing time).

Foundry moulds

The study of the foundry moulds drying with microwave method comes from the demand to reach a particularly fast drying, in shorter time than allowed by current methods. The traditional method using hot air impedes the achievement of comparable delivery, due to the characteristics of the hot air that, even if dried, still contains humidity.

With the microwave method studied by Microglass, it is possible to reduce time of the humidity diffusion from the deepest inner layers to the surface layers, using the traditional energy moulds only for humidity evacuation to the surface. Tests and trials showed that, even with reduced drying times, the humidity drops under 1% obtaining a high quality drying and reducing the defectiveness when using the moulds for metal and alloy flowings.
