Abstract

The crystalline structure of raw or waste gypsum is altered during calcination of the gypsum by treating it with sound frequencies, preferably in the range 485 to 515 Hz and for 20 minutes. The calcined and treated gypsum is then rehydrated in the manufacture of strong and fire resistant products, e.g. bricks and building materials. The apparatus used comprises a variable frequency generator, an amplifier and sound emitting speakers.

Description

2337514 1 CRYSTALLINE STRUCTURE ENHANCER This invention relates to a
Crystalline Structure Enhancer of the type that physically alters the dimensions and characteristics of crystalline structures.
Typical calcination of raw gypsum occurs between 960c and 1650c. This drives off dihydrate water of crystallisation to produce a hemi-hydrate product. When mixed with water the hemi-hydrate rehydrates as a dihydrate. The dihydrate has elongated fibrous crystals that interlock producing a plaster. The inventor has found a way to alter the crystals during their formation into a new product, in such a way that once they rehydrate they interlock to make a new product much stronger than it would have been otherwise. Furthermore, the chemical water retained inside the newly formed amorphic structures also has a capacity to help the rehydrate be more fire resistant than it would have otherwise been. Without the Crystalline Structure Enhancer the original type of gypsum plaster would not be very strong, with a typical compression strength of 3 Newtons per millimetre squared. There are millions of tons of waste gypsum stock piled around the world. By calcining this gypsum with the Crystalline Structure Enhancer, tests have already shown compression strengths in the region of 30 Newtons per millimetre squared. Furthermore, even using a crude method of calcination the Crystalline Structure Enhancer increased the plasters strength by 30%. This new product could be used to make bricks which have a typical strength of 7 Newtons, or used as a filler in fire resistant building materials.
The invention when applied to conventional gypsum calcination units will significantly alter the crystalline structure of the end product in such a way that it can increase its strength and fire resistance qualities. It will behave just as well when waste gypsum is being calcinated.
It's an invention which utilises designated frequencies (range 485 to 515Hz) to dramatically confer qualities upon crystalline structures not normally associated with those structures.
This novel way, which must be activated during the entire calcination process, advantageoulsy lasting twenty minutes, consists of a frequency emitting speakers.
generator; an amplifier and sound The number of each of the relevant sound equipment will vary according to the size of the calcination unit. The volume of sound generated must be sufficient to penetrate the raw or waste gypsum. The harmonic resonance of the sound is what changes the crystaltine structure of the hemihydrate bringing them greater uniformity and harmony in structure. The frequency should be variable so as to cope with regional variations in both structure and type of gypsum used. The base frequency for strong plaster is 495Hz and 505 Hz for more fire resistant products.
