Description
Technical field:
The crystallite foam heat-insulating board is a kind of silicate product among the present invention, belongs to the building materials industry product, particularly relates to a kind of method of utilizing kaolin to produce the crystallite foam heat-insulating board.
Background technology:
1, the kaolinic present situation of China
Kaolin is a kind of important nonmetallic minerals, with mica, quartz, lime carbonate and be called four big nonmetalliferous ores.
Mainly by forming less than kaolinite bunch mineral (kaolinite, dickite, nacrite, halloysite etc.) such as the small sheet of 2 microns, tubulose, laminated, the ideal chemical formula is AL to kaolin
2O
32SiO
22H
2O, its essential mineral composition is kaolinite and halloysite, except that kaolinite bunch mineral, also has other mineral associations such as smectite, illite, agalmatolite, quartz and feldspar, contains a large amount of AL in the kaolinic chemical ingredients
2O
3, SiO
2With a spot of Fe
2O
3, TiO
2And the K of trace
2O, Na
2O, CaO and MgO etc.The pure kaolin of matter have whiteness height, matter soft, be prone to dispersion suspension in water, good plasticity-and high cohesiveness, excellent electric insulation performance; Have good antiacid dissolubility, very low cation exchange capacity, physico-chemical property such as resistivity against fire preferably.Therefore kaolin has become tens necessary raw mineral materialss of industry such as papermaking, pottery, rubber, chemical industry, coating, medicine and national defence.Report that Japan is used to replace iron and steel to make aspects application such as cutting tool, lathe drill bit and oil engine shell kaolin in addition.Recent years particularly; The modern science and technology develop rapidly makes that kaolinic Application Areas is more extensive, and some high-technology fields begin to use kaolin as novel material in a large number; Even the high temperature resistant porcelain parts of reactor, space shuttle and spaceship, also process with kaolin.
China finds and utilizes kaolinic country in the world the earliest.The rag white pottery that Shang dynasty occurred before 3000 is processed with kaolin exactly.China's kaolin ore point has 700 many places at present, is 3,000,000,000 tons to 200 place's ore deposit point proven reserve, and ore deposit point comparatively disperses.The distribution of China's kaolin resource relatively disperses, and grade is not high, and great majority are Coaseries kaolin (abroad seldom); Need through calcining or modification; Being used for paper making and cloth coating has natural limitation, and Coaseries kaolin is difficult to the large scale mining utilization owing to belong to the associated minerals of coal.In China, non-Coaseries kaolin is suitable with the Coaseries kaolin reserves, but the overwhelming majority is a tubulose kaolin, and viscosity is big, can not be used for paper making and cloth coating.
Kaolin is the ubiquitous a kind of nonmetalliferous ore of occurring in nature; Past generally is used for producing pottery; Refractory materials and mix plastics is on a small quantity made filler in the rubber. growing along with each field of national economy, and People more and more is paid attention to kaolinic deep processing; Because so not only can obtain new material, but also can increase economic efficiency with property.The present invention promotes its industrial value for kaolin makes full use of a practicable method is provided.
, multicellular glass and crystallite foam heat-insulating board
Multicellular glass is also claimed sintered glass; Be to be rich in the base-material of glassy phase material with cullet, mica, flyash, perlite etc.; Add an amount of whipping agent, properties-correcting agent and pulverize mixing, in particular mold, have a large amount of evenly porous materials of pores through a kind of inside that preheating, fusion, foaming, cooling, annealing etc. are processed.The multicellular glass production application; Part has solved domestic refuse such as cullet, flyash and industrial residue rationally utilizes problem; A kind of light material of excellent performance is provided for the construction work industry simultaneously; Slow down environmental pollution to a certain extent, played the effect of environmental protection, had the environmental protection building material of good social effect and economic benefit.
The development of China's multicellular glass is than later, and up to the 80's, more domestic scientific and technical personnel bring into use cullet Development and Production multicellular glass; And obtain certain achievement; In this 30 years development process, Chinese development with developed multiple foam glass product, but the multicellular glass ubiquity quality problems such as physical strength is low, thermal-shock resistance difference on the whole; Big limitations its widespread use on building decoration and heat insulating; Cause domestic Foam Glass Industry Development slow, strengthen the scientific research investment dynamics, further improve the physicochemical property of foam glass product; Expanding its range of application, is to demand urgently at present dealing with problems and the trend of researching and developing from now on.
Multicellular glass is widely used abroad already, and has brought into play positive effect in a lot of fields, especially on construction industry.In Europe, area such as U.S.A, day and national multicellular glass is by mass production and widespread use; Wherein glass industry developed countries such as the U.S., Russia, Britain, Hungary, France, Czech, Japan, Germany have become the main production of multicellular glass, consumption, big export country; These countries have accumulated many experiences and technological achievement in the multicellular glass research and development are produced, and production technique is also constantly being improved and development.In recent decades, countries in the world have been developed colored acoustic foams glass, lamination multicellular glass, heat resistanceheat resistant radiation multicellular glass, building heat preservation multicellular glass or the like again.Though domestic production multicellular glass is main raw material with industrial cullet generally; Cost is lower; Be beneficial to environment protection; But because the shortcoming of low, the thermal-shock resistance difference of physical strength is limited to it as multifunctional material and materials for wall popularization and application, simultaneously also for the scientific and technical personnel that will be correlated with from now on clear and definite direction.
Multicellular glass and sytull have premium properties separately; A kind of New Building Materials of both advantages are the crystallite foam heat-insulating boards, and the crystallite foam heat-insulating board is that a kind of its inside has glassy phase, crystal mutually and be uniformly distributed with complex phase solid material such as a large amount of micro-bubble bodies.
