Description

The ceramic ware for daily use that a kind of corrosion resistance is high

Technical field

The present invention relates to domestic ceramics technical field, particularly relate to the ceramic ware for daily use that a kind of corrosion resistance is high.

Background technology

China's not only rich in mineral resources, is also coal production state maximum in the world and consumption of coal state, in recent years simultaneously Coming, China's thermal power generation quickly grows, and wherein great majority are with coal as fuel, and generated energy reaches 1.3 hundred million kW h, shared by thermal power generation Ratio 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, in a large number The discharge of flyash have received to be paid close attention to the most widely.China started just to how utilizing flyash as resource from 1987 The breach of comprehensive utilization, comprehensively utilizes it, becomes a long-range policy of economy and social development.Cullet class thing Its chemical stability of matter is extremely strong, without putrefaction, does not burns, can not degrade, and substantial amounts of cullet both took up an area, and polluted again environment, reclaimed Being to save the energy, the optimal path of protection environment with utilizing, and have good economy, the main component of glass is dioxy SiClx, it is possible to promote the sintering of pottery.In Production of Ceramics, firing temperature is the highest, and 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%, and 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, new technique, a large amount of uses of new equipment, pottery Porcelain yield also increases by a fairly big margin.New ceramics, as a kind of new material, solely sets one with the performance of its excellence at Material Field Flag, is paid much attention to by people.Domestic ceramics occupies an important position at Material Field as traditional ceramics material, because it Relating to the every aspect of people's life, the development of domestic ceramics is more wanted along with the raising of people's living standard proposes Asking, 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 are just with frightened The speed of people reduces, and is non-renewable resources, if can not find alternate resources, it is likely that can face No Assets later The difficult situation that can adopt.Yang Yuwei et al. is at " utilizing the industrial wastes such as flyash to prepare the research of a domestic ceramics " literary composition middle finger Go out, utilize the flyash of power plant emission, a large amount of useless saggars of ceramic industry generation, useless porcelain powder to utilize Orthogonal Experiment and Design to join Side, develops cleaning and produces the formula of domestic ceramics, wherein flyash, useless saggar, the content of useless porcelain powder be 10% respectively, 10%, 8%, applying this technology can be that enterprise brings considerable economic benefit, and the recycling for flyash finds an exit, although carry High Social benefit and economic benefit, but a lot of performance is not reaching to the requirement of people, the most antibacterial, high temperature resistance, freeze proof etc. The shortcoming that performance is the highest, service life is not grown.
