What does dps self test meanDPS self test
DPS introductionConcrete permanent set liquid DPS was first used in the United States in the 1920s, in the Second World War a large area of use in the underground military bunker, etc., waterproof and moisture-proofing role, many countries in the world have production. In the 1990s into China, and began to use in some domestic civil engineering construction of some concrete structures, the effect is very good. The effect is very good. It has been well received by the relevant units.
DPS OverviewIn the development of national standards in the country, defined as: water-based (or aqueous, water-based) permeable crystalline inorganic waterproofing materials; permanent condensate DPS DPS, that is, Deep Penetration Sealer (deep penetration of crystalline waterproofing materials) acronym.
Principle of reaction
Concrete permanent solution DPS waterproofing material is a water-based osmotic crystalline waterproofing material (water-based advantage is that there is water in the structural layer can continue to react until? Absorb dry? Water until). Its waterproofing mechanism is a chemical reaction with the free alkali in the concrete, generating stable dendritic crystal gel, can effectively block the concrete internal microscopic cracks and capillary voids, so that the concrete structure has a long-lasting waterproof function and better compactness and compressive strength. The depth of penetration is up to 20-30mm, and at the same time, it can effectively prevent the erosion of concrete by acidic substances, oil stains and motor oil.
Performance characteristics
Permanent solution DPS waterproofing material is not just a concrete waterproofing material, but also a concrete protector: it is resistant to acid and alkali, corrosion, and can resist high temperature changes! More resistant to chloride ions on the concrete damage erosion.
One does not need leveling layer and protective layer, directly on the concrete base spray 2 times can be;
Two impermeability level of S11 or more;
Three waterproofing of permanent condensate DPS and the same life of the concrete. Will not aging, deterioration;
four can be constructed in the wet work surface, maintenance period is very short, not afraid of rain;
five after pouring the base plate to do then waterproofing construction, you can save a long time of work;
six completely environmentally friendly and non-toxic, can be done on the interior walls of swimming pools sewage ponds and so on;
seven price is lower than the other materials;
eight construction is simple, easy and Fast! Each worker can construct 1000 square feet / day. Do not maintain, do not sprinkle.
Scope of use
Can be used in any case of concrete substrate (concrete surface wet can be constructed, but not open water). For example, basement, roof, kitchen and bathroom, bridge, tunnel, sewage tank, power plant, etc..
