Abstract

Provided is an unburned material gradient type curing method. After an unburned material is poured into a mold, the mold is put in a curing box capable of regulating and controlling temperature and humidity, the unburned material is subjected to heat preservation for a period of time at different temperatures, the temperatures are gradually changed from low to high, heat preservation is conducted at each temperature, and finally the mechanical strength of the unburned porous material is greatly improved. The method is easy to operate, and the process is easy to improve.

Description

A kind of unburned material gradient formula maintenance process
Technical field
The present invention relates to the maintenance process of a kind of unburned material gradient formula.
Background technology
Porous material refers to through high-temperature firing or does not burn gel and form, and has and communicate or the highly porous material of closed pore in body.Because of its there is excellent chemical stability, evenly perviousness, lower heat conductivity, resistance to high temperature oxidation, heat shock resistance, the aspect such as anticorrosive have excellent performance, be widely used in multiple scientific domain such as environmental protection, energy-conservation, chemical industry, oil, smelting, food, pharmacy, biomedicine, cause showing great attention to of global material circle.
For unburned material, its maintenance process becomes one of gordian technique, particularly important in whole production process, maintenance process not only becomes the gordian technique that mechanical strength improves, and directly affect the microstructure of unburned material, thus have influence on other performances of material, as heat conductivility, corrosion resistance nature etc., current country proposes the industrial economy that green economy develops into the impetus, porous material is greatly developed, and unburned porous material is again wherein one of of paramount importance development key technology, according to current unburned porous material the most the technology of difficulty be exactly ensureing under other performances situation about at least not reduced, how to improve its mechanical strength.
Summary of the invention
The object of this invention is to provide the maintenance process of a kind of unburned material gradient formula, to improve the defect existed in known technology.
For achieving the above object, unburned material gradient formula provided by the invention maintenance process is that after unburned material is injected mould, put into maintaining box, from low temperature gradually to high temperature transition, every section of temperature is all incubated for some time.
Described unburned material gradient formula maintenance process, wherein, unburned material comprises solid material and porous material.
Described unburned material gradient formula maintenance process, wherein, the temperature and humidity of maintaining box can regulate and control continuously.
The present invention has following beneficial effect:
The present invention is simple to operate, and process modification is easy.After unburned material injects mould, put into the maintaining box of temperature-controlled and humidity, be incubated for some time in differing temps, from low temperature gradually to high temperature transition, every section of temperature is all incubated, and finally makes the mechanical strength of unburned porous material be greatly improved.
Accompanying drawing explanation
Fig. 1 is unburned material microstructure prepared by the conventional maintenance process of comparative example.
Fig. 2 is unburned material microstructure prepared by gradient type maintenance process of the present invention.
Embodiment
Technical problem solved by the invention is to provide the simple gradient type maintenance technology of a kind of unburned porous material, it is simple to operate, be easy to improve in existing technique, can ensure when other performances of product do not reduce, still can greatly improve its mechanical strength, thus solve the problem in above-mentioned background technology.
In order to understand the present invention better, illustrate content of the present invention further by comparative example and embodiment below, but content of the present invention is not only confined to the following examples.
Comparative example:
Raw materials quality per-cent is quartz sand 70%, gelatinous material (cement) 25%, whipping agent 1%, auxiliary 4%.
1, quartz sand is put into ball grinder ball milling 3 hours, take out and obtain powder raw material.
2, preparing burden adding gelatinous material, whipping agent and auxiliary in step 1 gained material, loading in ball grinder, then add water ball milling 1 hour together, obtain the slip with numerous air-bubble.
3, step 2 gained slip is injected square model to be shaped, slight vibration mould, treats that slurry is smooth and gets final product maintenance.
4, by the depanning of step 3 gained base substrate, repaired biscuit, maintenance 4 days, make product, detection.The void content of obtained product is 55%, and volume density is 0.98g/cm 3, ultimate compression strength is 2MPa, and hole microstructure as shown in Figure 1.
