Abstract
The wall plate features its material proportion. It consists either of adhesive, fly ash, calcium carbide slag, gypsum slag and cement, or of mixture, adhesive, coal cinder, pearlite, reinforcing fibre, chemical glue and water. The chemical additive used includes cement early strength water-reducing agent and alkali fly ash excitant, and the reinforcing fibre used is medium-alkali glass fibre and/or organic fibre and/or wood fibre.
Description
The present invention relates to building material field, a kind of materials for wall that utilizes flyash partly to replace manufacture of cement---fly ash light hollow wall plate is provided especially.
At present, along with increasing of China's heat power station, the quantity of the flyash of annual discharging is quite surprising, is very big for this reason and in the expense of taking up an area of and store, and how to utilize flyash to make building board and has caused common concern both domestic and external.The method of countries in the world research and utilization flyash manufacturing from different perspectives wallboard.Make a general survey of the relevant patented technology of utilizing flyash and other industrial residue, we find that they exist, and flyash content is lower, and cement consumption is big, needs problems such as autoclaving.
The object of the present invention is to provide a kind of high fly-ash content, add other industrial residue, the coal ash light cored slab that the simple cost of technology is low.
The invention provides a kind of fly ash light hollow wall plate, it is characterized in that: this hollow wall panel system is a main raw material with the original state flyash, with carbide slag, gypsum, cement is formed agglutinate, and being aided with industrial cinder, boiler cinder, perlite is aggregate, is strengthened and uses staple fibre, chemical assistant and water form through stirring extruding, and the ratio of raw material is: (parts by weight):
(1) agglutinate:
Flyash: carbide slag: gypsum tailings: cement=40～60: 10～15: 4～5: 10～20
(2) compound:
Agglutinate: cinder: perlite: fortifying fibre: chemical assistant: water:
＝1∶0.8～1.2∶0.4～0.8∶0.03～0.05∶0.01～0.03∶0.8～1.1
Wherein chemical assistant is cement early strength water-reducing agent and flyash alkalescence exciting agent;
Fortifying fibre is medium-alkali glass fibre and/or organic fibre and/or wood fibre.Send in the stirrer after raw material measures by prescription and pour in the wallboard extrusion machine after the stirring, take high frequency vibration extrusion process, with the compound extrusion molding, squeeze is 5～20Kg, vibrational frequency 1500～6000 times/minute, amplitude 0.1～0.3mm, the super plate of natural curing 8～24h, temperature is more than 15 ℃, and relative humidity is greater than 70%, and stacking natural curing was finished product in 7 days again.
Compared with the prior art the present invention has following advantage:
1, it is very high to contain flyash in the agglutinate among the present invention, add other industrial residue simultaneously, total residue doping quantity can reach more than 80%, because the carbon content of flyash of the present invention is less than 3%, the 080mm sieve aperture tails over and is not more than 12%, increased the specific surface area of flyash, help the performance of its lateral reactivity, excite the lateral reactivity of flyash jointly by lime, gypsum and flyash excitant, improve the content of flyash in wallboard, reduce product cost, and make the use properties of sheet material require to be guaranteed.
2, the present invention has objectively alleviated the corrosion of alkali to glass fibre because flyash content height results in the low basicity of agglutinate, like this, both can bring into play the lateral reactivity of flyash, can guarantee the use properties of sheet material again.
3, the present invention adopts the vibration extrusion process, compares with teeming practice, have that density is good, water cement ratio is little, need the ash amount less, technology is simple, labour intensity is low, production efficiency height, thereby cost is low.
4, the agglutinate of the present invention's employing, time of coagulation and hardening of cement are suitable, but early strength is higher, and comparable other method shifts to an earlier date the demoulding, carrying.Mix part cement and help promoting need not goods early strength development to adopt traditional steam press maintenance method, only adopt natural curing, but both save energy, and easy production process has been saved facility investment.
