The advantages of glass production of canasite
Description:
Canasa is a complex glass raw material, which is a cemented aggregates of silicate compounds without any additives glass-forming components, but also clarifiers and obestsvechivaya.
This raw material is a bargain amorphous siliceous mountain rocks – volcanic and sedimentary: perlite, pumice, diatomite, Tripoli, flask, etc., of which the production of superior glass and crystal.
It has high dispersibility, uniformity and chemical purity.
In General, the composition canasite can be expressed by the formula:
xR2O•yRO•zR2O3•nSiO2•mH2O, where x, y, z, n and m are the numerical coefficients of the oxides.
From canasite to glass for various purposes, but still 25 brand new silicate products.
Peculiarities of technology of production of glass from canasite:
Technology of glass production of canasite has the following features:
– for the production of glass quartz sand must be cleaned from various impurities. Clear canasa no need
– dry method of preparation of the charge is replaced by the “wet method”, i.e. glass-forming components in the form of solutions and suspensions of nanoparticles are mixed in the colloidal solution,
– when glass is melted there is no need to add glass,
– the temperature of the melting process of glass are reduced by 250-300 degrees, which leads to fuel savings of 10% and reduce harmful emissions by more than 90%,
– excludes “liquid phase” obtaining the glass,
– quartz sand is completely replaced by amorphous rocks: perlite, pumice, diatomite, Tripoli, flask, etc.
The advantages of glass production of canasite:
– economical compared to the traditional way. The silica in the composition canasite included in the amphora or the hydrated modification, or hydropolitical two – or trivalent metals (Ca,Mg, Pb, Al, etc.). In the structure of the obtained silicate chemical bonding of the silica Si – O – Si bonds replaced by Si – O – Me and Si – O – OH, which have high free energy, therefore, require less energy for their destruction
– environmentally friendly,
– the method of synthesis canasitebased on mixing solutions or suspensions of glass-forming components that interact with each other during the synthesis process, it ensures absolute homogeneity,
– non-waste production,
– the content of the coloring impurities in canasite can be reduced to 10-3 – 10-4 %, because the original solutions (water glass, solutions of nitrates of Ca, Mg, Pb, etc.) are cleaned
– silicates of alkaline metals as the main components candidakrusei – have a high degree of purity, as the main coloring impurities after filtration, remain in the sediment.
Application:
– the melting,
– the production of glassware for different purposes,
– production of dark green bottles,
– production of half-white container products
– production of alkali-free glass fiber,
– obtaining glass-ceramic materials (ceramics),
– preparation of an amorphous silica of high purity,
– obtaining of the adsorbent,
– obtaining sodium aluminate Al(NO)3,
– getting the fertilizer type of potassium-ammonium nitrate,
– obtaining zeolites of type NaA and NaX,
– obtaining silicate filler – hydrocarbonrich of calcium (CaCO3 CaSiO3 nSiO2 mH2O) – for the production of paper (instead of expensive dvuoksid titanium)
– getting the filter powders
– production of alumina (not less than 98%),
– obtaining building materials: Pinetop, decorative and facing materials, made by sintering based on waste glass and others industrial waste, etc.
