Welcome to Shandong Mason Environmental Protection Technology Co., Ltd.!---Focus on the field of prefabricated green building products!
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.
Construction knowledge: an effective way to improve the adhesion of putty
Putty adhesion will directly affect the construction quality of the paint. Many projects find that the putty has poor adhesion during the construction process, but the exterior wall putty construction has been completed in a large area.
In-depth analysis of the causes of cracks in the external wall insulation mortar layer
In recent years, China's insulation building materials market has developed rapidly, but some problems have also appeared.
Teach you how to choose how to choose color steel plate
Analysis of color steel plate refers to color coated steel plate, which is a steel plate with organic coating. Color steel plates are divided into single plates, color steel composite plates, floor decks, etc.
In recent years, China's insulation building materials market has developed rapidly, but some problems have also appeared.
This is all due to its advantages that other materials cannot match. Nowadays, with the continuous progress and development of science and technology, it is also used in industries such as electronics, pharmaceuticals, and biology.
