PRODUCT MANUAL

It use low-energy modified semi-hydrated building gypsum as the gelling raw material with ultra-fine inorganic fillers and various polymer modified stimulants and multi-level aggregates to prepared into a single-component pre-made dry powder product, which is formed a high-fluidity slurry after mixing with water. It has a comprehensive cost-effective :it can be manual construction or mechanized large-area pouring and can realize automatic and accurate leveling of ground .It is a new type, green and high-tech floor engineering material, which can replace the traditional cement, sand and fine stone concrete construction. One leveling can meet the construction needs of all decorative surfaces. The finished surface can be thinly laminated with floor tiles and assembled with wooden floors , PVC plastic floor paste, epoxy and polyurethane floor paint, can be widely used in building indoor floor leveling projects.

ADVANTAGES

1. High leveling accuracy

After the gypsum self-leveling construction is completed, the three-meter measurement with a ruler can achieve a height difference of less than 2mm.

2. Good volume stability

Product volume change rate of -0.04%, no hollowing, no cracking.

3. Good quality of surface

Backfilling, raising and leveling are completed at one time. The thickness of 3mm-100mm can be poured at one time. Overcoming the shortcomings of cement-based self-leveling, which can only be leveled in thin layers.

4. Controllable construction thickness

One-time pouring with thickness of 3mm-80mm can meet different construction requirements.

5. High construction efficiency

After product is poured, people can walk after 4-6 h, it greatly shorten the construction interval time. Mechanized pumping and pouring is more than 5 times more efficient than traditional ground leveling construction.

6. Reduce building load

The hardened dry density of the product is about 30% lower than that of concrete, which effectively reduces the building load and improves the seismic grade.

7. Meet on-site environmental requirements

Dry powder transportation, wet pumping construction, no dust, no pollution, reduce the impact of road, environmental protection and control.

8. Reduce comprehensive cost

Using “APEX” gypsum self-leveling can save a lot of labor costs, time costs and management costs, and reduce the comphrehensive cost by more than 20%.

COMPARISON BETWEEN APEX GYPSUM SELF-LEVELING AND FINE STONE CONCRETE

Category	APEX gypsum self-leveling	Fine stone concrete	Comparison results
Intensity	C20	C20	Same
Dry density	1650kg/m³	2400kg/m³	Reduce weight by about 30%, effectively reduce building load
Air humidity adjustment effect	Adjustable air humidity 5%	Almost zero	More conmfortable and environmental friendly
Planeness	2mm/3m	5mm/2m	The overall planeness increased by 60%
Construction interval	Walk after 5-6h	Walk after 24h	Shorten the interval time by 80%,Construction efficiency increased by 5-10 times,greatly shorten the construction period
Construction efficiency	250-300㎡/people /day (Mechanical construction）	40-50㎡/person /day
Pave wooden floor/floor tile	Directly pave wooden floor、thin floor tile(Adhesive thickness about 5 mm, very fast paving speed) and increase the effective layer height	Pave the wooden floor after the second leveling;The dry paving method of the floor tiles has a thick layer of cement and large sand (the paving speed is slow) and the thickness is up to a few centimeters,and reduce the effective layer height	Increase effective space utilization

WAY OF ENGINERRING APPLICATION

1.Small area self-use environment

Use bagged products and use portable, self-service mixing methods to complete self-leveling pouring operations. It is suitable for household self-use, thin layer leveling or small-scale floor projects.

1.Big area portable environment

Use bagged products and use fully automatic integrated self-leveling pouring equipment for construction. Suitable for backfilling, raising and leveling floor works above 200 square meters and below 2000 square meters.

3.Large area pumping environment

In order to meet the requirements of large-area construction and improve the efficiency of construction operations, APEX independently designed and developed a special gypsum self-leveling special tank and high efficient intelligent self-leveling slurry conveying integrated operating system.A single set of self-leveling intelligent conveying equipment with a unit conveying capacity of about 20 m³/h in the case of bulk products .Taking 30 mm construction thickness as an example, a single set of equipment can reach 3000 m2/d if it meets the continuous construction operations. Equipment maximum vertical conveying height can be directly transported to 33 floor height (150 m), horizontal conveying distance up to 400 meters.20,000 square meters of buildings can be completed within 7 days.
