Product description

 

USE
HPB-80 is effectively used for directed destruction :
* All types of rocks, including butchering oversized , passirovku , office blocks from the array and so on .;
* concrete, reinforced concrete, stone, etc. objects. Heat destroys the object should be in the range of -10 ° C to + 35 ° C. Destruction is quietly , of fragments , vibration and gas emissions , is not accompanied by seismic effects on standing next to objects.

details Material
HPB- 80 is a powder-based material has a calcium oxide and alkaline properties. Material is dusty , not combustible , not explosive , the color from white to gray-yellow with different shades. Expansion pressure of 80-120 MPa (800-1200 kg / sq cm.) Consumption of dry matter per 1 meter of the hole diameter of 40 mm is 1.50 kg.

Preparing the mix
Sample preparation of 6 kg powder:
- in a bucket capacity of 10-12 liters pour 1.9 - 2.0 l water , to which is added carefully plasticizer Mixing Capacity SP-6 in the amount of 100-240 ml, after which the mixture is shaken. In the resulting solution with constant stirring in small portions to sleep 6 kg powder HPB-80 . If necessary, prepare a mixture of other quantities, the number of components is changed in proportion.
WARNING! - Carefully work out the amount of water taken from the powder mass HPB-80 . It should not exceed 30 - 34%. Otherwise, the expansion pressure drops. - Water temperature gauging HPB-80 in the summer should be between 10 ° C to 20 ° C in winter to 20 ° C to 50 ° C depending on the temperature of the destroyed object.

DRILLING NRV-3
destructible objects in boreholes drilled a diameter of 25 - 45 mm. The diameter of the hole and the last step is determined by the physico-mechanical properties of the material being destroyed, and the requirements to the size of the severed parts. The larger the diameter of the hole and the depth, the greater the pressure developed extensions. The depth of the hole should be between 70 to 100% of the required depth of destruction, depending on the properties of strength and ductility of the material being destroyed.
WARNING! - The lack of destructible objects three free intersecting surfaces required additional technological measures;
- Implementation of closed pits and grooves require special technological measures and equipment;
- The destruction of objects of small thickness (300 mm) require special technological measures;
- Increasing the diameter of the hole and the reduction of its depth leads to the danger of the working mass ejection HPB-80 from the hole.

FILLING blasthole
After preparation of the working mixture is poured in the hole last until full completion . While working with the finished portion of the mass should not exceed 10-15 minutes. Boreholes before pouring cleans the dust and debris by blowing. If there is water in the hole, you should delete. With the high water absorption of the destroyed material (old concrete, fractured rock) hole pre-filled with water, but before pouring it into the working masses HPB-80 the water is removed.
WARNING! filling in the mass HPB-80 boreholes should be shielded from rain and direct heating by solar rays .
STORAGE
Store in a dry place on wooden pallets at a temperature not exceeding 20 ° C. Shelf life - 6 months.

SAFETY
* When working with HPB-80 , wear safety glasses, dust mask, gloves;
* In case of contact with skin or eyes, rinse immediately with water and seek medical advice;
* Never look in the hole, because in violation of the rules of cooking HPB-80 the spontaneous emission of a mixture of the hole.

PACKAGING
* 50 kg bags. Plasticizer inhibitor complete .
