Extension of Hainan factory direct high-strength wear-resistant materials TD-DFH1 simple inexpensive construction

I. Description of high-strength wear-resistant material is a new type of inorganic composite materials. It has a simple construction, fast, impact resistance, erosion resistance, high temperature, thermal shock resistance, and overall good, easy to repair, etc., and inexpensive, easy to transport. Second, the use of metallurgy, mining system slag trenches, ore trough, lining material libraries. Coking coal, the electrical system in the coal slot, coal hoppers, silos, etc. lining. Chemical building materials (cement) system silos, hoppers, library wall, and so on lining. Water conservancy, hydropower, ports and other anti-erosion, abrasion resistant surface. Third, the technical indicators (implementation of the standard: JC / T906-2002) compressive strength of the elastic modulus of the high temperature wear properties roughness coefficient thickness ≥65 MPa ≤ 0.4kg / m2 ≥4.0 × 104MPa ≥500 ℃ ≤ 0.015 ≥ 40 ~ 50 mm Fourth, the construction profile 1, construction equipment and tools compulsory concrete mixer or self-loading concrete mixers. Vibes or plate vibrators. 2, the construction preparation 1, the concrete base ① clean up the base surface treatment, without gravel, floating pulp, floating dust and mold release agents and other debris. If the base surface loose parts should be removed. ② concrete foundation for vertical or inclination larger, should be arranged medullary nail (with Φ6 ~ 8mm steel, length 30mm, Y-shape, plum blossom nail spacing 250mm). 2 hours ago ③ construction should be fully wet the base surface. 2, steel primary treatment ① steel surface rust, remove grease and other debris. ② arrangement medullary nail (in the form of supra). 3, stirring mixer should be as close to the construction location, to facilitate the continuous construction. Stirring the water should be clean water, do not use water, wastewater, and water containing impurities. The high strength and wear-resistant material into the mixer, and then start the mixer, dry mix for 1 minute. The weighed water into the mixer, and then stirred for 2 to 3 minutes. Using self-loading mixer should be appropriate to extend the mixing time. 4, the construction ① before the start of construction, should remove residual water-based surface, brush with a good concrete interface treatment agent evenly brushing the surface of the concrete foundation, and while it was dry immediately be cast construction. (See Instructions concrete interface treatment agent) ② The high strength and wear-resistant material poured into the template, then use vibrators vibration, vibration time should be based on high performance wear material surface pan slurry prevail. Such as thin layer construction, when not to use vibrator, may also be plaster-type construction, the construction should pay attention to tapping compacted surface of the pan until the syrup. Then calendering treatment after construction to ensure smooth surface without floating pulp. ③ from high-strength wear-resistant material mixing with water to control vibration molding should be finished within one hour is appropriate. 5, conservation conservation measures should be consistent with the relevant provisions "of reinforced concrete construction and acceptance of" the.
