Construction method of acid proof brick
Construction methodLining adhesive layer, mortar protection layer: lining carbon brick before, in the bottom board first put a layer of delta =3mm cement whole surface layer, in order to protect the lining layer and avoid mortar joint layer appear blind seam, curing at normal temperature after masonry.Positioning, layout and layout: according to the bottom of the groove size, first play the central cross line, then positioning, line, according to the line for typesetting, painting, cutting and numbering.Lining procedures: masonry procedures from low to high, the first base, the rear wall, the Yin angle, the facade to suppress the plane, Yang Kok plane cover the facade.Masonry method: the bottom and wall are all made by squeezing, kneading and extruding, and they are made by line by line, layer by layer, block by block.The prepared mortar evenly scraping on the three surfaces of carbon brick (i.e., on the back end, and then squeeze (side), rubber hammer) is dense, the ash seam and the combined layer clay full, squeeze out excess clay to eradicate. The surface shall be made of flat and vertical, rows and rows, and the seams between floors and layers shall be staggered.
QAGrassroots requirements: after the acceptance of the rubber lining, clean, keep clean and dry.Construction conditions: temperature at 15-30 Deg. C anti-corrosion construction is appropriate, the relative humidity is less than 80%, according to the temperature change adjust the dosage of curing agent, low temperature, humidity is too large, should be used to wet machine to adjust the temperature and humidity on the construction site.The construction of anticorrosive engineering is afraid of water and is afraid of drying.The preparation of mortar and glue is strictly carried out according to the proportion, and it is used up in the prescribed use time.
Construction preparationFamiliar with drawings, specifications, technical disclosure, do a good job of the handover process.Material preparation: the anti-corrosion materials used in this project are stored in the appropriate warehouse (site), and the incoming materials are tested to comply with the requirements of the HGJ229-91 specification.Equipment preparation: cutting machine, mixer, grinder, trolley, cement plate, rope, hose, shovel, wipe, steel scraper, rubber hammer, steel wire brush, brush, putty knife, the level of scale, by foot, rope, wire, small pendant, Jue measuring cup, scales, tarps, ventilation and lighting equipment.
