New building materials natural characteristics of anhydrous plaster analytic

Natural Anhydrite plaster raw materials rich in anhydrite earth storage of natural materials, is a highly efficient energy-saving, environment-friendly building decoration interior plastering materials, strong adhesive, plaster surface smooth, dense, delicate, used in aerated concrete substrate effect is more significant, plaster layer does not appear hollowing cracking phenomenon. stone coated metal roofing tile

With respiratory function, can skillfully outdoor humidity control within the appropriate range, creating a comfortable working and living environment.
Experiments show that the product is ideal for fireproofing material, which can effectively prevent the spread of flame, fire capacity of up to four hours or more, with excellent fire resistance. stone coated metal roofing tile
After the construction of the wall can be 20-52 dB noise, but also a good sound-absorbing material.
Products as interior building decoration materials with good insulation properties. stone coated metal roofing tile
Use of the product can effectively improve work efficiency, setting and hardening fast, easy mechanized construction.
Use of the product can effectively reduce the overall costs plaster works, with excellent value for money. stone coated metal roofing tile
Construction Technology
One of the primary wall surface uneven and flat seams tick or with 1:3 cement mortar fill level processing. stone coated metal roofing tile
2, the wall before plastering should be adequate watering moist, but not the substrate surface with clear water.
Aerated concrete block can watering a day in advance, more than twice a day drenched, to ensure its water depth of more than 10mm.
Hollow concrete masonry cut watering can one day in advance to ensure that its concentration in water is about 5mm. stone coated metal roofing tile
Brick, cement mortar base watering a day in advance, to ensure its water depth of about 10mm, before construction can be re-watering moist.
3, different substrates in the wall and the wall corner joints should be pasted fiberglass mesh, lap width of not starting from the phase at the duplicitous side of not less than 100mm. stone coated metal roofing tile
4, slurry preparation
Underlying plaster: You can manually mixed gray, also can be mechanically mixed with ash. According to a certain ratio of gypsum mortar mortar required Stir immediate use.
Surface layer of plaster: first join mixing bucket of water, then add the powder mix, stir, can be used. stone coated metal roofing tile
Mixing the slurry with water to be clean and free of impurities in drinking water.
5, the construction operation
Construction should first determine the plaster line and order, to ensure continuous operation works. stone coated metal roofing tile
According to the flatness of the wall grass and decorative requirements should be set marked tendons.
In the relatively flat wall plaster, its plastering thickness of 8mm or so, once completed, can also be layered construction, as a result of uneven walls or other requirements, plaster thickness exceeding 8mm, then layered construction . The lower layer of the slurry should be carried out after the initial setting; when the plaster thickness greater than 35mm should be taken to strengthen measures.
Calendering underlying pulp before the final setting should be carried out (on-site press with your fingers, somewhat dry and hard, can still be pushed out when fingerprints), scraping feet close to the title, scraping up and down, and then plastering calendering . stone coated metal roofing tile
Overlay should be at the bottom after the final setting of plaster, thickness is generally 2-3mm, can be completed. Surface pressure light before the final setting.
Plastering process of cleaning up the floor and when dressing scrape, rub off the paste should not be recycled. stone coated metal roofing tile
Precautions
Waterless plaster construction temperature controlled at 0-40 degrees Celsius.
Slurry should have been condensed water use.
Winter construction must ensure that the slurry without condensation situations.
Should not be specified in the wall or frequent water contact with parts of the use environment.
Avoid sudden temperature changes in the wall plaster environment (such as the construction of the wall in summer sunlight)
Transport, storage requirements: sun, moisture. Shelf life: 6 months
