Extension of TD-DSL1 cement self-leveling cement I. Introduction Extension of TD-DSL1 self-leveling cement is a special cement, aggregate refined, European professional auxiliaries and additives, etc., and mixed with water to form a slurry, with strong self-leveling; suitable for resilient flooring, wood flooring, carpet and other grassroots leveling, pre-leveling epoxy floor, and old cement mortar or concrete floor renovation. Suitable for indoor dry ground. The thickness of the coating in 0.5-10mm Second, the technical data mixing ratio: 25kg flour (bag) is about 6-6.5 liters of water (depending on the construction of temperature) consumption: about 1.5kg / m / mm constructability time 20 minutes Pedestrian time: about 5 hours after can shop floor time after about 24 hours at room temperature more than 20 degrees data only applies Third, technical indicators (Executive Standard: JC / T985-2005) Model: TD-DSL1 project performance flow degrees / mm, the initial fluidity fluidity ≥145 ≥160 20min tensile bond strength / MPa ≥1.3 wear / g ≤0.40 Dimensional change / impact resistance 0.04% from the floor without cracking or 24h compressive strength / MPa ≥15 24h flexural strength / MPa ≥5 compressive strength grade rating C16 C20 C25 C30 C35 C40 28 d compressive strength / MPa ≥16 ≥20 ≥25 ≥30 four, features a large mobility, automatic leveling ground fine . 2, fast-setting and early strength, improve construction efficiency. 3, low consistency, easy construction. 4, for floor heating. 5, to improve the lower strength to prevent cracking. Fifth, prepare a grassroots base surface must be dry, solid, load-bearing, clean, no cracks, no adverse residual adhesive objects. Especially the grassroots deficiencies: bumps, dents, cracks, grease, dust, etc. must be fully processed and repair. Sanding, grinding or shot peening according to grassroots. Then dust with a vacuum cleaner. 2, good tensile strength and compressive strength of concrete. 3. Check the base surface flatness and moisture content, moisture content "4% (CM method): a high moisture content grassroots needs Extension of waterproof material handling using. Especially for new concrete or mortar grassroots grassroots ground floor, it is recommended to be checked for moisture content. 4. Extension of the use of multi-functional interface agent to be met after the dry state, and no fluid can be carried out self-leveling laying. Sixth, a construction, primer has been absorbed grassroots, when dry up state (2-6 hours after the primer construction), construction began leveling. 2, adding 6-6.5 liters of water (emphasis strength) or 6.5-7 liters of water (focus on spreading rate) in a container, then slowly add a pack of 25 kg of TD-DSL1 self-leveling, with a mixer and stir until evenly without group slurry, let ripening about two minutes, stirring once again briefly, pour syrup mixture, evenly spread, with special tooth scraper Scraping mouth to control thickness. Just a good mix coating to prevent direct sun off by strong winds. Inadequate ventilation or low temperature had a significant effect on the drying time is extended. 3, the initial setting before self-leveling, using a defoaming roller roll bar into the ground to eliminate the mixing of air. 4. Laying interval within 10-15 minutes as well, to make the phase boundary formation. 5, such as the construction of a multi-layer self-leveling need to lay in between each layer need to use multifunction interface agent Extension of primer (the previous layer to dry for 24 hours), to ensure construction quality. 6, laying in the grass-roots non-absorbent tiles such as self-leveling time, should be laid at least 2 mm. Seven, to protect the product contains cement, there is a strong alkaline reaction with water, avoid contact with skin and eyes, after inadvertent contact with the skin or eyes, immediately rinse well with water. When fully cured no harm to health and ecology. Eight, note 1, the goods in the transport, storage should be strictly rain and moisture. Construction of the temperature of not less than 5 ℃. 2. Do not Tuoda brand and other brands of self-leveling, self-leveling mix. 3. Please do not use this product for long wet grass roots or outdoors.
