Plaster mortar, a product description plaster wall plaster mortar is a new material. Semi-water gypsum substrate for polymer gelling materials, inorganic fillers and by dry mixing. Is a new and improved interior painting materials, changes in cement-based cementitious material traditions, with a variety of substrates wall has excellent compatibility and adhesion. Second, the product advantages 1. crack, sound and heat insulation. 2. Automatically adjust the indoor humidity, a "breathing" function. 3. The strong adhesive, firmly bonded to the substrate, easy to crack. 4. good workability, simple construction. 5. The construction speed, short cycle. Third, the product scope 硂 wall, the inside wall of the external walls of each household, aerated blocks, light sand filling block, brick and other matrix and various household wall compartment wall, every stairwell Thermal insulation. Fourth, product standards: "SGF plaster mixed mortar application of technical regulations" JG / T015-2009 No. Item Unit Performance 1 Appearance quality ---- pale granular powder 2 Setting time initial set h≥1.0 Final setting h ≤8.0 3 loose bulk density Kg / m3 1500 4 compressive strength Mpa≥5.0 5 water retention --- ≥90% 6 shrinkage --- ≤0.1% 7 ---- A grade combustion performance level five, plaster mortar Performance comparison with cement mortar plastering Category Advantages Disadvantages apply a base plaster mortar, good adhesion, for a variety of substrates. 2, light weight, good maneuverability construction, less ash fall. 3, setting hardening fast, saving period. 4, drying shrinkage, not hollowing cracking. 5, fire function well, can mediate the indoor humidity. 6, low cost, good green, energy-saving effect. 1, mortar using shorter. 2. Construction workers need to adjust habits. Aerated concrete cast concrete panels and a variety of polystyrene insulation slurry cement fly ash brick products a higher strength. 2, good water resistance. 3, the traditional plastering materials, easy to use. 1, poor adhesion, easy to produce hollowing. 2, shrinkage, easy to crack. 3, the operation more ash fall. Suitable for six brick construction construction process to prepare primary treatment → → → formulated mortar wall stickers cake → 1:2 layered plaster primer → pure plaster overlay. 3.1 ready to use pre-construction deal with plaster and relevant examination, according to the factory quality certificate, performance test reports, manual, etc., with the necessary test pressure test, grasp the strength of plaster, the agglomeration, damp plaster Mortar shall not be used. Mixing water using the water. Gather iron trowel, wood trowel, care gray board, gray pots, 2m aluminum foot scraping and plastering tools such as shovels, unified specification tin pail, tin making a mix of gray tank and other tools. The plaster mortar shipped to Face. 3.2 Primary treatment grassroots level surface irregularities tick repair parts, dust, debris clean, regular watering moist; in concrete and ceramic concrete masonry (aerated concrete masonry) phase at wide paving ≥200mm big eye glass screen. Glass screen to be pasted firm, smooth, in a tight state, shall not exceed the pre-control plaster layer thickness. 3.3 The preparation of the slurry wall plaster mortar into the mix tank, slowly adding water wet mix until the convenient operation. During the construction process should be strictly controlled batching workers to ensure the strength of plaster mortar. 3.4 bottoming when plaster thickness> must be strictly hierarchical leveling when 8mm, bottom ash thickness control in each 5 ~ 8mm, pending the final set and then wipe down one layer; scraping along the wall vertical and horizontal ruler direction close to the ash cake scraping to find, until leveling up, rub with a wooden trowel compacted hair. Base flatness is not required to meet the requirements bottoming direct plaster mortar overlay surface layer. After 3.5 Overlay bottom ash hardened final setting, you can be overlay; pure plaster overlay operation, survived two passes, control the thickness of about 2mm, the first pass is used to make flat gray mortar and trachoma enhance the adhesion between the overcoat and gray bottom ash, and the second time for the calender gray overcoat, calendering ≥3 times the number of times to ensure that the surface bright and smooth, consistent color. 4 Note (1) plaster during storage and transportation process should prevent moisture, storage time should not be too long, in principle, should be used up within three months; the use of a small amount of lumps found, use should be sifted. (2) The initial setting time of plaster mortar general ≤1h, final setting time ≤4h; it is not a gray mortar mix when mixing too much, to avoid the use of water in the process of mixing the secondary use to make plaster or reduced strength loss, resulting in rework losses. (3) the construction is completed, to promptly clean up the doors and windows, hydro line pipe, structural layer, etc. residual mortar. Strengthen product protection, keep indoor dry and ventilated. (4) applies only to plaster dry indoor environment, bathroom, kitchen and other moist environment is strictly prohibited
