specifically introduced: first remove the surface of the earthen dust, milk skin, loose particles, etc., treated The surface should reveal fresh crust, and do not disturb the bone material, rinse clean with pressure water, air-drying, it is appropriate to use sand blasting, blasting machine, crucity surface planer and other hair-spraying methods or pressure water spraying, hair depth control within 1 to 3mm. The surface of the crucible has a partial bulge beyond the plane, ground with a grinding machine, the surface honeycomb, hemp surface and other defects, need to be cut with a cutting machine, the surface cracks need to chisel, remove loose particles in the groove, with a wire brush to remove debris, sand particles to clean, dry, and then apply a thin layer of epoxy-based liquid on the surface, and finally filled with epoxy mortar, and with a hot mud knife to smooth. When the strength of the backfill site is not lower than the strength of the surrounding crucity, then hair.
then the bottom coating 20min to 60min (to three consecutive hand contact brushing to 10mm disconnect), before applying epoxy mortar. Paint should be mixed with, such as the gel should be discarded, the bottom coating such as loss of viscosity should be reapplied, the bottom coating requirements thin and uniform, no flow hanging, no exposed bottom; Epoxy mortar thickness of 10mm, error range of ±1.0mm, flatness requirement error range of ±5mm, at the same time, according to the specification requirements to detect the mortar coating and the base bonding strength.
coating maintenance age of 7 days, maintenance period requires to ensure the maintenance temperature, prevent water seepage, rain immersion, impact, etc. ; To 50mm interval seams, to 1 to 3d epoxy mortar curing and then fill the gap seams, fill the construction requirements of solidification and flattening, construction surface to be level with the construction blocks on both sides, no fault platform, no obvious seams.
Before construction, fix the thickness ruler at the edge of the construction block, and then apply epoxy mortar, construction should be applied, edge pressurized, side to find flat, after applying epoxy mortar 30 to 60min, until the initial solidified mortar to carry out pulping, surface collection; Joining marks, drops, cracks, foaming, hemp surface and other phenomena, if found should be timely treatment, serious people must chisel out the heavy wipe;
