Light Weight Block (AAC block)
The Performance Advantage:
Lightweight: Porosity achieve 70% to 85%, volume density is generally 500 ~ 900kg/m3, as 1/5 of general concrete the 1/4of clay, the 1/3 of hollow brick, and similar with wood can float in water. It can reduce building weight, reduction in the cost of integrated building.
Fireproof: Most of the major raw materials is inorganic materials, so it has good fire resistance, and do not emit harmful gases when meet fire. Fire 650 degrees, as a refractory material, the thick up of 90mm walls can reach to 245 minutes fire resistance, 300mm thick up wall can reach to 520 minutes fire resistance.
Sound insulation: Due to a unique porous structure, so it has a sound absorption capacity. The sound absorption capacity can reach of 10mm thick wall up to 41 db.
Insulation: As the material inside has a large numbers of the pores and porous, which has a good thermal insulation properties. The Thermal conductivity is 0.11-0.16W/MK, as 1/4-1/5 of brick. Typically, the insulation effect of 20cm thick aerated concrete wall is equivalent to 49cm thick solid brick walls ordinary.
Permeability: Result of material by the composition of many independent small pores, the moisture absorption is slow, in the volume of absorbent is 5 times of clay saturation do. When used in the bathroom, the wall can be treated to interface directly paste tiles.
Anti-seismic: The same building structure, improve the two seismic than the brick level.
Pro-environment: Manufacturing, transportation, all use the process of pollution, to protect arable land, saving energy, is one kind of a green building material.
Durability: material strength is stability, in the specimens tested after one year of atmospheric exposure; the intensity increased by 25%, and remained stable after ten years.
Shortcut: it has good machinability, can be sawed, planed, drilled, nailed, and available appropriate as bonding of adhesive material, so create favorable conditions for building construction.
Cost-saving: An integrated lower cost than using more than 5% of solid clay bricks, and can increase the usable area, greatly enhance the utilization of floor space.
Electrical slurry meter
It is a meter (refer to the picture) used for measuring the powder before slurry feeding for mixing.
5.Pneumatic butterfly valve:D671J-10-150
The meter is composed of chamber, support ring, load sensor and pneumatic butterfly valve.
The drum shapes like a truncated cone, which make the discharge quick. It is made of rolling steel and there is washing pipe inside.
The support ring is made of steel and there is chamber on the top and the support ring below it, and there are 3 load electrical sensors hang among the chamber and support ring, and there is pneumatic butterfly valve in the discharge drum to control the program.
When the slurry is fed into the chamber, the electrical sensor will transfer the weight to the display automatically, and it will output the signal to the computer. The discharge is controlled by the pneumatic valve.
Shut off the power supply after each shift, and clean the drum wall, in order to make sure the powder weighing is accurate
Clean the dust on the sensor and weighing display.
It should follow the instruction when operate the meter
No other current is allowed to go through the electrical sensor, for example, when weld the ground wiring.
Do not sunshine the weighing display, and avoid any sudden temperature change and vibration
The meter has been calibrated before ex-factory, do not change.
No one is allowed to stand around the machine when feeding the slurry.
