How to make a foam block: production technology and specific equipment selection

Some manufacturers of foam used in their work special barosmesiteli, others - prefer mixers with submission of the finished foam from a special foam generator, and others - use the method of dry foam mineralization.

If we consider the classical production of foam blocks technology, it is important to note that in accordance with its pre-prepared foam must be mixed with mortar.And this principle is reflected in the work of all of the above listed types of equipment.

foam concentrate and a certain portion of the water are dosed in accordance with the volume, and then they are mixed in the foaming agent.From there, the mixture enters the foam generator, which is brought to the desired condition.At the same time preparing mortar mixture consisting of sand, cement, fiber and calcium, and this product is connected to foam in a special mixer.That's foam is formed, and then it is delivered directly to the place of installation or pre-prepared forms for blocks.

manufacturing foam blocks Technology: injection molding or Cutting

Once construction is prepared mixture, proceed directly to the manufacture of aerated concrete blocks.They may be made by molding or by cutting technology.Moreover, according to experts, foam block, which has the cutting manufacturing technology, has a rough surface that is capable of applying to it the plaster or other finishing materials easily.But to make these units more complex than alloy, so they got on the market less common.

Manufacturing technology of foam blocks : injection molding and Cutting

Injected same foam block manufacturing technology involves the use of special metal battery molds with a clearly defined cell size.These form the finished foam is poured, and then he just needs to harden.Pouring the mixture into the molds is carried out without the use of vibration - surface foam is spread only by using a special metal ruler.A shuttering mold after curing the mixture is carried out in stages:

  • knock locks form;
  • recline side;
  • removed dividing walls that form the individual cells;
  • removed finished blocks;
  • spread finished blocks to a special wooden pallet.

And removed from the mold blocks, whose production technology has been the injection, using special mechanical tools and instruments.Here, considerable importance is the manual labor.

important to note that the foam concrete blocks manufactured by the injection molding technology often differ from each other in strength and density.Furthermore, their geometrical dimensions can vary somewhat (usually in the range of 1 - 5 mm).And the production of special metal molds can be associated with certain difficulties.Therefore, producers in each case individually to decide whether to give preference to the molding or cutting technology manufacturing units, carefully weighing the pros and cons of both methods.
