Crack use rubber cement concrete crack repair brand

I. Features: 1, cement cracks in plastic in liquid form, easy to carry out concrete repair small cracks. 2, building and structural damage, the infusion of plastic reinforced, it could effectively restore its integrity, and the appearance is not damaged. 3, non-volatile solvent, basically does not shrink when cured. 4, with good toughness and impact resistance. 5, operational for a long time, after curing adhesive strength. 6, has a good resistance to water, oil, alkali and acid medium capacity. Second, the scope of application: 1, used in pouring concrete crack repair, concrete walls, floors, basement crack repair construction perfusion. 2, is widely used in steel-encased steel stick, bridge strengthening works. Third, the safety performance indicators: Performance Project performance physical properties of gravity (25 ℃) (g / cm3) 1.6 Viscosity (25 ℃) (cps) 3500-4000 operational time (25 ℃) ≥1 hour curing time (25 ℃) ≤7 day colloid properties Tensile strength (MPa) ≥30 tensile elastic modulus (MPa) ≥3.0 * 103 Elongation (%) 1.3 Bending strength (MPa) ≥45 without brittle failure compressive strength (MPa ) ≥65 bonding capacity tensile shear strength (MPa) ≥15 Steel - Steel uneven pull off strength (kN / m) ≥16 steel - steel adhesive tensile strength (MPa) ≥33 positive pull adhesion and concrete bonding strength (MPa) ≥2.5, And for concrete cohesion destruction environmental performance in line with the requirements of the actual non-toxic health grade four, Construction Description: 1, steel and concrete should be surface-treated adhesive surface, steel surface rust, polished, and with wipe clean the concrete surface should be polished. 2, the cement cracks glue AB glue component in accordance with Part A: B component = 4: 1 ratio of good after weighing into the container, stirring until uniform color (usually 2-3 minutes) to winter or low temperatures, AB component can also be 4: 1 ratio operation. 3, each time stirring the glue quantity must not exceed 5 kg to 2 kg is appropriate. 4, according to the design requirements for infusion construction, all parts easy to lose adhesive wall with clay were sealed to prevent loss of glue. Fifth, packaging, transportation, storage: 1, the product is metal pail, standard packaging specifications for A component 4 kg / barrel, B groups were 1 kg / bottle, according to user requirements to provide 25kg + 6.25kg / group packaging specifications. 2, this product does not belong to flammable, can be air, sea, rail and road transport. 3, light up the goods transportation, loading and unloading should be in, rain, sun-proof, can not be inverted. 4. Storage time: The glue storage for one year at room temperature, the performance did not change significantly. 5, Part B long storage process prone to discoloration is normal, does not affect the amount of the product performance and use.
