Compared with the traditional brick-concrete structure house, the integrated house with the new building material system has irreplaceable advantages: (container house rental) The wall thickness of the general brick-concrete structure house is mostly 240mm, while the prefabricated house is in Less than 240mm under the same area conditions. The indoor usable area of the integrated house is much larger than that of the traditional brick-concrete structure house.
The integrated house is light in weight, less wetland work and short construction period. The thermal performance of the house is good, and the wall panel of the integrated house is a foam color steel sandwich panel with heat insulation. Then, most of the building materials used in the integrated house can be recycled and degraded, and the construction cost is low, and it is a green and environmentally friendly house. In particular, the brick-concrete structure is not environmentally friendly, and a large amount of clay is used, which destroys the ecology and reduces the cultivated land. Therefore, the breakthrough and application of integrated housing in technology will be long-term, which will change the traditional construction mode and make the living cost of human beings. Smaller, better living environment. It can play an important role in environmental protection.
Integrated residential frame steel anti-corrosion and rust:
One: We need to consider whether the matching of the paint is correct. We know that most paints are based on organic colloidal substances. After we coat each layer of paint into a film, there will inevitably be many tiny pores. Therefore, the corrosive medium will enter and corrode steel. Now the construction of the coatings we are in contact with is not a single layer but a multi-layer coating. The purpose is to reduce the microporosity to a minimum, and there should be good adaptability between the primer and the topcoat. Such as vinyl chloride paint and phosphating primer or iron red alkyd primer will have a good effect when used together, but it cannot be used together with oily primer. Since perchloroethylene paint contains strong solvents, it will destroy the primer paint film.
Two: Of course, the primer, intermediate paint and topcoat of anti-corrosion coatings must be used together. (Container prefab leasing) Compared with the general painting requirements of components, and using hand and power tools to remove rust, two primers and two topcoats can be used. For components with high requirements for painting and spraying to remove rust, it is advisable to use two coats of primer, 1-2 times of intermediate paint, and two coats of topcoat. The total thickness of the dry paint film of the coating should not be less than 120μm, 150μm , 200μm, of course, for some parts that need to increase anti-corrosion, the coating thickness can be appropriately increased, 20-60μm. For the coating thickness to be uniform, non-toxic, continuous and complete, a good anti-corrosion and anti-rust effect can be achieved.
Three: Consider the possibility of construction conditions, some are suitable for spraying, some are suitable, and some are dried to form a film, etc. In general, dry, easy-to-spray, cold-set paints should be used.
Four: The use conditions of the structure and the consistency of the selection of coatings should be considered, and the selection should be made according to the conditions of the corrosive medium, gas phase and liquid phase, humid and hot areas or dry areas. For acidic media, the acid resistance can be better. Compared with alkaline medium, epoxy resin paint with better alkali resistance should be used.
