Clay construction should be carried out following technical regulations.
A material mixing ratio (by weight)
Clay powder: potassium silicate (water glass) = 100: 36-40
Mortar material: potassium silicate (water glass) = 100: 20-25
Concrete: potassium silicate (water glass) = 100: 18-20
According to the above mixture ratio should be based on the construction site across the country climate, temperature and temperature-site commissioning, commissioning and the proportion of the construction site for the re-construction.
Second, pre-construction to do the lining substrate rust, degreasing, decontamination cement grassroots moisture content of not more than 6%, and attention trim uneven parts, and dried.
Third, when the artificial stirring APPLIED square head small soldering iron, the clay and a good proportion to said potassium silicate full mix evenly, should have sufficient consistency and mobility, and use within 30 minutes.
Fourth, the construction site temperature should be between 15 ℃ -33 ℃, relative humidity should not exceed 75%, and construction should take an open-air shed rain and sun.
Fifth, when the lining-brick panels, clay should be full, and with a rubber hammer shock asperities make it smooth. When the puzzle should support large brick prevent displacement.
Sixth, good equipment lining, flooring should be the last layer of masonry time regimen for 14 days more than 15 ℃ environment, health prohibited during contact with water and steam.
Seven, according to a certain proportion of added sodium silicate attention, can not pay more!
Construction Common problems and treatment methods
The basic reason
The temperature difference between day and night
Heated above 15 ℃ (day and night)
Measures taken to exhaust dehumidification
Add excessive water glass
Ventilation dehumidification, heating
By adding the proportion of water glass
Curing too fast
High proportion of sodium silicate
Dehydrogenation incomplete curing agent
Adjust the proportion
Low temperature with high specific gravity, high temperatures with low specific gravity (1.40-1.42)
Note that the quality of the curing agent
Local color crack
Improper construction order
Horizon construction inside and outside after the first
Take the sun shed
Application of plastic sheeting for ceiling construction
Masonry fall off
Masonry rust without a net
Cement substrate surface loose
Local temperature soldering
Local severe vibration tapping tune
Carbon steel substrate Bo Hou uneven
Before construction of masonry rust, oil, dirt Ex
The loose surface cleaning
After construction is strictly prohibited local high temperature welding, percussion
Pre-construction inspection plate thickness
Masonry shift seepage acid
Masonry were not too big support
Mortar joint is not full
Bottom acid concentration below 10%
Take measures to support
Using mortar kneading extrusion method to make full
Field test acid permeability
The diurnal mean temperature curing product of not less than 15 ℃, relative humidity less than 75%, and 10% for the acid, after going to be tested, and then construction.
