Model is introduced: the user can according to different construction conditions, to select the corresponding repair mortar. Chimney wall repair is often used commonly have the several types of repair mortar type reinforced type chimney wall repair mortar, usage simple, single component. Add water mixing construction directly, weak alkaline. And acid-proof daub general! Repair the type of this product is a two-component, powder and liquid ratio of 4:1, with the need to stir the liquid before, and then slowly add powder to mix! Construction. Epoxy type epoxy type chimney wall repair mortar, into three components, AB material for epoxy emulsion, C material for polymer filler. First, stir well, turn the AB packing to stir to mix well. Scope of application: this product can be used not only on the inner wall of the chimney repair, A. Repairing and strengthening of civil construction, Bridges, roads, railways, tunnels, DAMS and other concrete structures) 。 B。 Repairing and strengthening building structures ( Column, beam, plate, wall sections, coating repair) 。 C。 Repairing and strengthening chimney structures ( Reinforced concrete, brick, castable, such as substrate) Construction method: base treatment will be required for internal chimney repair parts loose chisel in addition, with wire brush will repair the osteoporosis, floating ash, oil, rust, etc. , clean up. Will hew out of the base surface with tools of smooth rough surface, to ensure strong repair layer binding. Dealing with the leakage corroded reinforced rust removal. Rinse with water wall repair, is required to ensure that repair surface clean. Stir before use will be A shake, and then press A material: B = 28 material mixture and toss the mixing proportion of the uniform glue paste can be chimney wall repair use. Reference dosage of 1700 kg/m3. Repair manual first batch of scraping the mortar layer thickness control compaction at around 3 mm with a spatula. To repair the defect parts within a construction thickness should be 2 cm, thickness of more than, appropriate hierarchical construction, DI 2 - layer construction About 3 hours, can di 2 batch of scraping. Repair mortar mixture slurry should be finished in 1 hour. Spraying slurry before you use A shake, and then press A material: B = 28 material mixing proportion of mixture and stir evenly glue paste can be used. Reference dosage of 1700 kg/m3.
