Ampoule polymer type ADP
Polymer ampoules are used for chemical anchoring in the roof, sides and soil of mine workings of mines and mines, as well as in metro construction, tunnel construction, foundations and other structures.
The polymer ampoule of the ADP type is a two-chamber polymer shell of cylindrical shape containing a polyester composition mixed with mineral components and a hardener. The ampoule can be made for both manual and mechanized installation.
Depending on the curing rate of the composition , the following brands are installed:
ADP-M — "slow" — ampoules with a long curing time;
ADP-C — "average" — ampoules with average curing time;
ADP-U — "accelerated" — ampoules with a short curing time.

Note:
1. At the temperature of the ampoule and the mine air below +20 ° C, the mixing time and anchor retention in the hole increases and is determined experimentally. At the temperature of the ampoule and the mine air above +20 ° C, the mixing time and anchor retention in the hole decreases and is determined experimentally.
2. Gelatinization time is a symbol of the time from the moment of complete mixing of the polyester–polymer composition with the polymer composition hardener to the moment when the viscosity of the mixture reaches a value of 50 Pa · s, not including the mixing time.
3. Full curing time is the time from the moment the polyester–polymer composition begins mixing with the polymer composition hardener until the composition is fully cured.
