German Chongqing New Asia alkali cement factory 13,311,126,842 German Chongqing New Asia alkali cement factory 13,311,126,842 German Chongqing New Asia alkali cement manufacturers 13311126842 Description: alkali cement mortar is a strong base class for aggressive media erosion resistant ability of the special mortar. Imported (neutral) alkali cement, sodium and lithium-based silicon powder as cement hardener materials, special import natural stone and aggregate particles and alkali-resistant sealing additive, strictly in accordance with a certain proportion of SCA, and then the powder mixer and stir percent, lower than the configured compacting cement, impermeability and alkali corrosion good alkali cement mortar, is a special anti-corrosion material, it has the use of simple, low cost, on-site water can be use, etc., have been widely used in domestic and anticorrosion. Features: High-alkali cement mortar should have a high compressive strength and durability (mainly referring to the barrier level). Below 50 ℃ resistant to concentrations of 35% or less of sodium hydroxide and then 50-100 ℃ can resist a 15% -20% sodium hydroxide, and sodium aluminate, sodium carbonate, ammonia, lye and lime and other corrosion. Specifications: AL2O3,% 25 ~ 30 Fe2O3,% ≤ 2.0 SiO2,% 65 ~ 70 bulk density, g / cm3 ≥2.20 derivative multiplier (350 ± 5 ℃), W / m K ≤0.9 Apparent porosity,% ≤20 Cold crushing strength, Mpa ≥65 0.2Mpa load softening start temperature, ℃ ≥1300 water absorption,% <12 compressive strength: according to the test method hardeners, after 28 days compressive strength is 65N / mm2 Hardness: Resistance alkali land Ping Mohs hardness value of 6.1. Surface hardness according to JC / T906-2002 standard ≤3.90mm (straight indentation diameter). Flexural strength: Alkali Floor: ≥6.9 N / mm2 (JC / T906-2002 standard ≥6.5 N / mm2) purpose: used in chemical plants, oil refineries, pharmaceutical intermediates factory, fertilizer plants, citric acid factory floor and other heavy alkali land. Factory and underground repository for all kinds of saline areas. A variety of basic alkali corrosive media, floors, walls, pool, tank, etc. structural engineering. Health and safety alkali containing Portland cement floor, if there is contact with the skin to stimulate the weak alkaline. If your eyes are contaminated, wash immediately with plenty of water clean, and seek medical treatment. The amount of storage: the proper use of alkali-resistant flooring material volume: ≥ 10kg / m2, the storage period of at least 12 months. Product packaging material is sealed with 25 kg polyethylene bags.
