Ceramic proppant equipment expansion model theory and guiding significance

1,  Ceramic proppant   correctly grasp the gas evolution: gas evolution is the fundamental factor of expansion Ceramic proppant, it's essential to correctly grasp. Expansion model theory allows us to design or process control in the recipe, can be more accurately grasp the ceramic body fat bad gas, so that the liquid is always being neither completely inhibited the expansion force to meet the requirements, but also have a certain The release, shrinkage reducing the pressure, and does not cause a lot of gas escape, the liquid phase of its inhibition difficult. This is the raw material gas composition of hair is particularly important.

2, correctly grasp the liquid volume and viscosity of the liquid: liquid volume and liquid viscosity is ceramic Ceramic  Proppant  equipment produced the most basic conditions to form a good swell. If the liquid is insufficient, it can not produce a large amount of gas wrapping body, if the liquid is too large, it will be too strong inhibition, leaving the gas expansion force is excessively suppressed, ceramic green body can not be expansion. The viscosity of the liquid also have a great influence on the expansion, the greater the viscosity of the gas, the stronger the inhibition. When the liquid viscosity is too small, the restraining force of the gas can not reach, the body produces excess gases to escape. Ceramic to swell it up. When the viscosity is too large, the restraining forces and excessive gases ceramic body blanks may be completely suppressed, ceramic expansion also not up.

Expansion model theory can guide us to correctly grasp the amount of liquid and liquid viscosity, roasting manipulation it has to have some of the expansion of early inhibition, so that most of the gas can not escape, resulting in some blanks in vivo expansion pressure, will a small amount of gas to escape, to create conditions for the late systolic pressure. It is not too big and not too small, should be resisted in order to achieve this effect as the standard. We can design accordingly formulation and process control.

3, correctly grasp the expansion section of different technical characteristics: If no expansion mode theoretical guidance, we may make the hair is always in the air surrounded by liquid state suppressed or let hair escaping gas has been in a strong state, and to promote best expanded condition. If expansion mode with new theories to guide production practices, we will let the gases produced by body, neither has been in a state of being surrounded suppressed, nor handling the escape state. Contraction pressure conditions created later in the later expansion of the gas pressure is less than the liquid surface tension of service, in a suppressed state and contract under reduced pressure, and to close the opening hole, thinning, forming the front expansion retrusion process.
