Abstract
A method for making the non-burned brick is characterized by that the electrochemical complexing principle is used to transform its hydrophilicity to permanent hydrophobicity and improve its compression and antiflex cracking strength.
Description
The present invention relates to a kind of no-firing brick, claim non-burning brick manufacturing technology again, is non-burning brick water-proof improvement, belongs to the materials for wall of construction work: the brick of building a wall.
No-firing brick claims non-burning brick again, is to add jelling agent lime, cement and admixture thereof with clay inferior or industrial residue to solidify, and through vapor cure, a kind of energy-saving brick of building a wall that does not need sintering to form.
This brick not only is suitable for developing country and builds the low price dwelling house, and countries such as the flourishing U.S. of industry, Japan, Brazil, Denmark, France, also all developing this energy-saving brick of building a wall energetically in order to cut down the consumption of energy and to reduce construction engineering cost, Denmark begins one's study in nineteen sixty-eight and non-burning brickly applied for a patent in 1971, develop equipment in 1972, and obtained patent.
China starts from the fifties to non-burning brick development, is presided over by the period-luminosity dragon professor of Hunan engineering college, and produces sintering-free clay brick, has built experiment type building, through the test in more than 30 years, proves that this brick has good performance.On September 1st, 1980, China Taiwan Mr. Zhao Zhikong obtains the patent of sintering-free clay brick production technology.China each province develops non-burning brick production over surplus in the of ten year, and has obtained gratifying achievement.
Non-burning brick is raw material with clay inferior and industrial residue, does not account for the good farmland, without roasting, non-environmental-pollution, obvious energy conservation, technology is simple, equipment is few, and the visual appearance of brick is good, the ultimate compression strength height, in architectural design, can use by the masonry structure value, but since non-burning brick water-intake rate height, poor water resistance, and folding strength and full water intensity are on the low side, therefore the application in construction work is limited to, at present only for low-rise building that is used for the 1-3 layer and farm house.
The object of the present invention is to provide that a kind of water-intake rate is low, water-tolerant, folding strength and the high non-burning brick manufacture method of full water intensity, make non-burning brickly in construction work, to be widely used.
The present invention is the electrochemical complex scheme of utilization polyacrylic acid and polyoxyethylene, and the degree of compactness that makes the wetting ability semi-hydrophilic of clay and industrial residue change into permanent hydrophobicity and raising adobe realizes.
Non-burning brick raw clay is the ore crystalline particle that changes through mineralogy, is called colloid.The structure of clay is octahedra or tetrahedral from lattice structure, and this structural molecule makes their particle surface produce static charge, the balance mode of static charge be negative charge mainly inside and positive charge mainly in outer rim.These static charges produce electrostatic force attraction to the electrode of water molecules, and water molecules is adsorbed on particle surface.
The clay particle stratiform silicate that is otherwise known as, the stratiform that lattice structure forms causes small bits of clay to present the fish scale shape, causes some clay particles that very big surface-area is arranged.The static brute force of these surfaces and water makes the wide area surface combination of water energy and grogs, and combination water has just become expanded or drying shrinkage with the process that loses water, and expanded or shrink process reduces non-burning brick resistance to compression, folding strength greatly, so that change original inherent form.
Non-burning brick intensity reduces mainly relevant with the water enchroachment (invasion) evil.Moisture makes non-burning brick expanded transition when rainy weather is too much, so that deliquescing and strength degradation.
Polyacrylic acid has a kind of powerful ionization in water, the positive ion neutralization on it and clay and industrial residue fly ash grain surface, the water molecules displacement of grogs surface adsorption is become free water, make grogs and flyash surface lose electrostatic adhesion power to water, the non-burning brick moisture content that no longer absorbs that is compacted, the strength degradation that then non-burning brick expansion and shrink phenomenon cause just can not take place yet.Polyacrylic this ionization is permanent, irreversible result.In case and the neutralization of clay and fly ash grain is just no longer walked by water-soluble.
Polyacrylic acid also generates a kind of insoluble complex compound in the water molecules on displacement grogs and fly ash grain surface, have the solidification that lubricity is brought into play similar cement, helps the compacting of adobe and improves early strength.
The present invention compared with prior art, the advantage that has: 1, non-burning brick degree of compactness significantly improves, and void content obviously reduces, resistance to compression, folding strength improve greatly.2, because the electrostatic adhesion power on clay and fly ash grain surface is neutralized by major part, stopped the infringement of moist and water after the compacting basically, made non-burning brick have stable resistance to compression, folding strength.3, reduced absorption, improved non-burning brick water tolerance, non-burning brickly be widely used in construction work thereby make to water.
Technology and operation
1, technical process: (employing semi-dry pressing)
Raw material pulverizing--Jia lime or cement--measured moisture content and optimum moisture content---maintenance that Jia PAA stirs--moulding--.
2, schedule of operation:
A, clay inferior is pulverized, is made it particle diameter between 2-0.074mm, and 0.074mm
Grain should be no less than 25%, requires particle too between 2-0.074mm to flyash.
B, survey total water content and optimum moisture content hit experiment.Mix thoroughly by proportioning raw materials.
C, moulding: moulding in brick pressing machine, compactness should be greater than more than 95%, but also manual assembly.
D, maintenance: spray 1-2 time every day with 0.01%PEO solution, can reach maintenance and want in continuous three days
Ask.
3, proportioning raw materials 1: clay: 25-30%
Flyash: 55-60%
Slaked lime: 10-15%
PAA:2kg/m
3(by volumeter after the compacting)
Proportioning 2: clay: 25-30%
Flyash: 55-60%
Lime: 7-8%
Cement: 2-3%
PAA:2kg/m
3(by volumeter after the compacting)
Claims (2)
1, be that the clay produced of hydrophobizing agent is non-burning brick with polyacrylic acid, polyoxyethylene, industrial residue is non-burning brick.
2, be the various non-burning brick of hydrophobizing agent production with the acryllic acid polymkeric substance.
