Description

A kind of high-strength impact-resistant life domestic ceramics

Technical field

The present invention relates to domestic ceramics technical field, particularly relate to a kind of high-strength impact-resistant life domestic ceramics.

Background technology

China's not only rich in mineral resources, also it is coal production state maximum in the world and consumption of coal state simultaneously, in recent years, China's thermal power generation quickly grows, wherein great majority are with coal as fuel, generated energy reaches 1.3 hundred million kW h, and thermal power generation proportion has reached 79.6%, thus causes flyash discharge capacity to increase year by year.In the end of the year 2010, discharge capacity reaches nearly 300,000,000 tons, and the discharge of a large amount of flyash have received to be paid close attention to the most widely.China started just to how utilizing the flyash breach as comprehensive utilization of resources from 1987, comprehensively utilizes it, becomes a long-range policy of economy and social development.Cullet its chemical stability of class material is extremely strong; without putrefaction, do not burn, can not degrade; substantial amounts of cullet both took up an area; pollute again environment; reclaiming and utilizing is to save the energy, the optimal path of protection environment; and there is good economy, the main component of glass is silicon dioxide, it is possible to promote the sintering of pottery.In Production of Ceramics, firing temperature is the highest, firing time is the longest, and energy consumption is the highest, according to heat Balance Calculation, firing temperature often reduces by 100 DEG C, then unit product heat consumption can reduce by more than 10%, and firing time often shortens 10%, then yield increases by 10%, heat consumption reduces by 4%, so reduction firing temperature and time have significant energy-saving and emission-reduction social meaning.Over nearly 20 years, ceramic industry enters developmental stage with rapid changepl. never-ending changes and improvements, and new technique, a large amount of uses of new equipment, ceramic yield also increases by a fairly big margin.New ceramics, as a kind of new material, is taken the course of its own at Material Field with the performance of its excellence, is paid much attention to by people.Domestic ceramics occupies an important position at Material Field as traditional ceramics material, because it relates to the every aspect of people's life, the development of domestic ceramics proposes more requirement along with the raising of people's living standard, and the most antibacterial is to propose most common requirement at present.Due to the wilderness demand of porcelain, a large amount of exploitations of china clay resource reduce the most with surprising rapidity, and are non-renewable resources, if can not find alternate resources, it is likely that can face the difficult situation that No Assets can be adopted later.Yang Yuwei et al. the article pointed out " utilizing the industrial wastes such as flyash to prepare the research of domestic ceramics ", utilize the flyash of power plant emission, the a large amount of useless saggar that ceramic industry produces, useless porcelain powder utilizes Orthogonal Experiment and Design formula, develop cleaning and produce the formula of domestic ceramics, wherein flyash, useless saggar, the content of useless porcelain powder is 10% respectively, 10%, 8%, applying this technology can be that enterprise brings considerable economic benefit, recycling for flyash finds an exit, although improve Social benefit and economic benefit, but a lot of performances are not reaching to the requirement of people, the most antibacterial, high temperature resistance, the performance such as freeze proof is the highest, the shortcoming do not grown service life.
