Description
Affiliated technical field
The invention discloses a kind of production method of devitrified glass, belong to glass material and production technical field.
Background technology
Devitrified glass is microcrystal and the equally distributed material of being made through control crystallization behavior by parent glass of glassy phase.Devitrified glass is owing to combine glass and the premium properties of pottery, thereby be widely used in electronics, chemical industry, biomedicine, mechanical engineering, military affairs, building and various fields of recent life as structured material, technologic material, optics and electricity material, material of construction, finishing material etc., have wide application prospect.The method for preparing devitrified glass at present both at home and abroad has three kinds: scorification, sintering process and colloidal sol---gel method.The scorification technological process is with the glass melt straight forming, obtains devitrified glass through the nucleus crystallization processing again.The advantage of scorification is: 1. goods density height, pore-free.2. be easy to moulding.Shortcoming is: 1. the crystalline phase ratio depends on the whole crystallization ability of parent glass in the devitrified glass.2. the crystallization process is difficult to control.3. whole crystallization time length, production efficiency and yield rate are low.The sintering process technological process is that the glass melt shrend is obtained particulate material, and particulate material obtains devitrified glass through high temperature sintering again.The advantage of sintering process is: 1. the whole crystallization time is short, and crystallization is easy to control.2. production efficiency and yield rate are higher.Shortcoming is: 1. upper layer densification depths shallow (about 2mm).2. the pore between glass particle is difficult to get rid of, and compactness is than scorification difference.3. product easily produces distortion, fireproof die is required high.Colloidal sol---gel technique is the novel process of low temperature synthetic materials.The advantage of colloidal sol---gel method is: 1. preparation temperature is low, has avoided in the preparing glass charge some component to volatilize when high temperature.2. can prepare the crystallite broken glass of composition in strict conformity with design requirements.Shortcoming is: 1. the production cycle is long, cost is high.2. environmental pollution is big.3. contraction is bigger in the gel sintering process, the yielding and cracking of goods.
Summary of the invention
For avoiding above shortcomings part in the present various devitrified glass production method as far as possible, the present invention take into full account and basis in conjunction with scorification and sintering process advantage on, a kind of production method of devitrified glass is provided.
The present invention is for solving its technical problem by the following technical solutions: a kind of production method of devitrified glass, comprise sintering process batching, mix, found, the shrend oven dry, cross screen sizing, the technological process that makes the shrend glass particle and scorification batching, mix, found, make the technological process that glass melts body, it is characterized in that: the shrend glass particle that makes respectively in above-mentioned two common process and glass are melted body mix; Then make the devitrified glass finished product according to conventional moulding (the conventional method of forming and the float glass process that comprise glass), coring, crystallization, polishing or cutting technique step successively again.
In actual production process, the technology of present method most critical is: granularity, grain composition and the add-on of control shrend glass particle.
The present invention has following advantage and positively effect:
1. glass melt is with after glass particle mixes, and glass melt has been filled the space of glass particle, has prevented the possibility that pore produces, and devitrified glass compactness is improved.2. grain composition by control shrend glass and add-on, controlled chilling speed can be controlled the crystallization process of mother glass, and whole crystallization ability strengthens.3. compare with scorification, physics, the chemical property of devitrified glass slightly improve, and compare with sintering process, and physics, the chemical property of devitrified glass improve a lot.4. can shorten the time of coring and crystallization, reduce the temperature of coring and crystallization.5. the inventive method is suitable for the preparation devitrified glasses such as the conventional method of forming of particle melt calendering formation, float glass process moulding, particle melt mixing cast molding and glass.Therefore can expand the scale of production, reduce production costs, improve quality, yield rate and the business economic benefit of product.6. the inventive method can also be used for production complex function devitrified glass and matrix material.
There is data to show, calendar year 2001, the ultimate production of China's crystallizing glass decoration board only had ten thousand square metres of 60-80, and these crystallizing glass decoration boards nearly all adopt sintering process production, product percent of pass is mostly at 50-70%, and China is thousands of times of existing production to the demand of crystallizing glass decoration board.Therefore, the present invention can improve product percent of pass if carry out the industrialization transformation under the working condition of sintering process or scorification, expands the scale of production, and reduces production costs, and will have very wide development prospect, can produce huge economic benefit and social benefit.
