Abstract
The present invention uses building slag as raw material, adds magnesium oxide as initiating agent, magnesium chloride as solidifying agent and inorganic chemical material adjuvant, and adopts self developed equipment to make the invented baking-free hollow block wall brick which can be used as bearing wall brick and has high strength.
Description
The present invention relates to a kind of building waste and handle resource utilization system baking free hollow wall building block technology.It adopts the solid waste that stays after house building, housing demolition and the house repairing (to be called building waste, do not comprise clay), after fragmentation,, react, solidify through normal temperature with multiple inolrganic chemicals, make baking free hollow wall building block, can be used as bearing wall brick.
In recent years, along with development and national economy, the building construction of China is maked rapid progress.It is also cumulative to build the building waste that stays behind the house, and contaminate environment has become public hazards.At present, more flourishing city all takes to collect, the method for landfill is handled building waste, a large amount of soils and fund have been taken, influence very big, government department very pays close attention to for this reason, experts and scholars also actively develop building waste and handle comprehensive utilization of resources research, for example sintering brickmaking and cement concrete brickmaking etc.But find in the test that the wall brick pressure intensity and the water tolerance that make all do not reach the national standard requirement, be difficult to promote.
The unburned knot of a kind of made from construction refuse resource system baking free hollow wall building block of the present invention, many rounds, normal-temperature reaction are solidified, and three-waste free discharge belongs to cleaner production, meets the national policy rules.
The characteristics of a kind of made from construction refuse resource system baking free hollow wall building block of the present invention are intensity height, heat insulation, insulation; Freeze-thaw-; Fried piece, crack are not burned in big fire, also are so even meet the water flushing, can reduce the generation of fire failure; Meet State Economic and Trade Commission's materials for wall innovation Tenth Five-year plan requirement and novel wall material and will adapt to the improvement of building function and the requirement of building energy conservation.
The present invention realizes by following measure:
1. building waste is handled
Construction waste crushing is become below 1 centimetre, as brick-making raw material.
2. main raw material
Building waste, magnesium chloride solidifying agent, magnesia dopant and auxiliary agent.
3. fill a prescription
Prescription sees table 1 for details.
Table 1
| Material name | Weight (gram) | Material name | Weight (gram) |
| Building waste | ????40-80 | Magnesia dopant | ????20-30 |
| The magnesium chloride solidifying agent | ????20-50 | Auxiliary agent | ????0-10 |
4. major equipment
Stirrer, pressing machine, mould.
5. baking free hollow wall building block shape and specification
Baking free hollow wall building block is shaped as rectangular parallelepiped, many rounds, the end is arranged.Wall brick specification 390 * 190 * 190mm, 390 * 190 * 115mm.But according to the customer requirements modular in design.
6. technical process
(1) building waste is transported to crusher in crushing just; (2) with pneumatic drawing and pulling type light body foreign material such as plastics film are separated; (3) picking wood, iron and steel, aluminium spare; (4) with crusher construction waste crushing is become particle below 1 centimetre, send into storage bin as raw material; (5) with each composition of measuring instrument continuous measurement, be delivered to stirrer; (6) continuously stirring is delivered to (mould is Drawing-Core, and is afterburning up and down, hydroforming) in the pressing machine adobe mould again; (7) just solidify; (8) pile; (9) the above maturation of solidifying of normal temperature 5 degree; (10) finished product dispatches from the factory.
