Description
Parameters
Magnesium Oxide Fireproof Board does not contain asbestos, formaldehyde, benzene and harmful radioactive elements, in case of fire smokeless, non-toxic, no smell. The production material is natural mineral powder and plant fiber, the production process of natural conservation, less energy consumption, no pollution, energy saving and environmental protection, the use of the board does not contain powder. It has the characteristics of fine, uniform and dense hole, coefficient of thermal conductivity is 0.216 w/cm, k, than lime-sand brick cutting w/cm, 1.1 k more insulation, saving energy consumption,
with its unique natural fine pore structure, combined with other heat preservation material, can be made with good performance of heat preservation of fire prevention board, can adjust indoor temperature, make a room and office more comfortable and warm.
Tips: Is the interface agent the same as the interface mortar?
For example: (1) Porous and strong water-absorbing materials (aerated concrete, gypsum board, wood, etc.); (2) Smooth and low-water-absorbing materials (cast concrete, etc.)
[Construction] Flat coating construction process of elastic coating for exterior wall
Let the new cement on the wall mature for at least one month to reduce the alkalinity of the wall appropriately and make the wall dry. The moisture content of the wall must be less than 10%; if the ambient temperature is low, the wall is ready to dry The time has been extended accordingly.
The quality supervision department has taken action, and the public wall requires the use of water-resistant putty
Shandong Weihai Quality Supervision Station requires that from October 1, 2016, the stairwells and corridors of new residential construction projects need to be scraped on the walls of public parts on the ground
【Construction】Scrape putty in this way so that the wall will not be hollow and cracked
The putty layer is hollow and blistered, mainly due to the presence of gas between the base layer and the putty layer. There is a dense layer between the base layer and the putty layer.
