Sell Sand aerated concrete production line

The main raw materials of Sand aerated concrete production line are lime-sand, lime, sand and cement, gypsum as well as water and steady bubble agents do additives. Sand aerated concrete production line is mainly to make these raw materials processing and mixing well respectively and then pouring them into the mould, after static curing and gas evolution , The green brick is cut to the autoclaved maintenance These production process make the sand aerated concrete products.

1, sand:

provide silicon materials and calcium materials for reaction, generating hydration products, ensure the intensity of the bricks. Sand is also for skeleton, reduce the contraction of the bricks. Sand is the core materials of bricks

Requirements: without impurities (bark, grass roots, etc), calcium carbonate content (coral, shells, etc) less than*0%, which should comply with the standard of (JC/T*******6) .

2,Llime:

(1)  Provides effective Ca O (Ca O) and fly ash silica (SiO2), the 3 oxidation 2 aluminum (Al2O3) transamination hydration calcium silicate and hydration aluminum Acid calcium, guarantees the strength of the products;

(2)  The lime also provides alkalinity and prompts aluminum powder and gypsum reaction and gas evolution

(3)  The action heat of the lime hydration makes the green brick hardening.

3, Cement:

Provides calcium materials, ensures the intensity of the bricks. The main function of the Cement guarantee the stability of casting, accelerate the hardening of green brick and the intensity of the cut green brick.

4, Gypsum (adjust material) :

(1) It makes inhibition function in a cement early hydration action, prevents   hesitation-set phenomenon of the cement;

(2) Restrains lime digestion, makes the digestive time prolonged, and reduce its final digestion temperature;

(3) Effects in aluminum reaction, the production of aluminum contain sulfur acid calcium;

(4) Improves the strength of the green bricks and products, reduces contraction rate and improves the frost resistance.

5, Water: the purpose of adding water is to make sure the pulp material can stir well, ensures the slurry poured into the mold smoothly, and can be active and gas evolution.

6, steady bubble agent: It is the surface active substances, which reduces the tension of surface. Has ability of foaming and stability performance of bubble.

It has a lot in common between Sand aerated concrete production line and fly ash aerated concrete production line. The detailed process in the process need not be detailed here.

1, no radioactive

The raw materials of the Sand aerated concrete products are natural quartz sand, it does not produce any pollution in production, transportation and using process, and it is a good green building materials products, absolutely no radioactive.

2, good heat preservation performance

The thermal conductivity of the Sand aerated concrete block is 0.*1 w/m.k. The heat preservation effect is six times than the clay brick, as well as*2 times the normal concrete. It usually uses **0 mm light sand aerated concrete block as the external wall, which not only meet the strict requirement of heat preservation and heat insulation no needing assisting heat preservation material but also the effect is better than fly ash aerated concrete products

3, fire prevention function

The raw materials and products of the Sand aerated concrete block isn't burn. The experiment proved that light sand aerated concrete is the ideal fireproofing materials, The*0 cm thick wall of fire prevention ability is up to 4 hours, which is widely used as a firewall.

4, high intensity

The main raw material of the Sand aerated concrete production line is sands, whose aerated concrete block is more intensive than the fly ash aerated concrete block.
