Shijiazhuang cement pavement leveling adhesive, Shijiazhuang cement pavement surface repair materials, stone house ..

Concrete surface leveling adhesive when the concrete surface smooth enough, the use leveling adhesive repair, so that carbon fiber sheet to be able to stick straight in the concrete surface. Moderate leveling of the company specializes in the production of adhesive, easy to scratch coating, high strength. First, the product uses mainly used for reinforcing CFRP primary surface of the concrete structure. High viscosity putty-like, strong bond, anti alternating load performance, has excellent mechanical properties, good toughness, wear resistance, corrosion resistance, waterproof. Second, the technical indicators in line with the technical requirements of GB50367-2006 standard. Performance Project Performance Requirements (with A-grade rubber match) test results for individual assessment colloidal properties of colloidal Tensile strength (Mpa) ≥30 48 Qualified colloid bending strength (Mpa) ≥40 and shall not brittle (cracked like) destroyed 56, and not brittle (cracked like) destroyed qualified and concrete are tensile bonding strength (Mpa) ≥2.5, And for concrete cohesion destruction ≥3.2, And for concrete cohesion destruction Eligible Notes: 1. Positive pull adhesion and concrete bonding strength test, concrete blocks were destroyed. 2. Concrete strength grade:. C50 3. sample preparation ratio: A: B = 2: 1 (W / W) Third, the use of methods and precautions 1, leveling adhesive A, B during storage and transportation, such as precipitation, please Before using a hand drill Stir respectively. 2, leveling adhesive component A: component B = 2: 1 ratio well mixed use. 3, the product density is 1.40 ~ 1.50g / cm3 (cured), mixing time can be about 20 to 60 minutes (23 ℃). First a gel time of about 1.5 to 6 hours. Fourth, packaging, storage 1, The product is packaged A6.6kg + B3.4kg / group. 2, the product can be stored at 5 ℃ --40 ℃ below ambient temperature, the shelf life of nine months. 3, the product should be stored away from open flame, heating devices. ************************************************** ****************************
