Inorganic binders

Small, complex-shaped glass articles such as thread guides for the textile industry and television gun mounts for the electronics industry are made by the multiform process. The dry-milled powder is mixed with an inorganic binder and a fluid vehicle, and then atomi2ed by a spray dryer into small, dried agglomerates of glass powder and binder with good flow characteristics. They are subsequently pressed to the desired shape and fired. 

Paints are complex formulations of polymeric binders with additives including anti-corrosion pigments, colors, plasticizers, ultraviolet absorbers, flame-retardant chemicals, etc. Almost all binders are organic materials such as resins based on epoxy, polyurethanes, alkyds, esters, chlorinated rubber and acrylics. The common inorganic binder is the silicate used in inorganic zinc silicate primer for steel. Specific formulations are available for application to aluminum and for galvanized steel substrates. 

Silanes. Silanes and silane derivatives dominate the small market for inorganic binders. These materials are used both m combination with organic binders and by themselves. As co-binders, they increase the chemical and moisture resistance of a film, When used by themselves, they form brittle, very chemical-resistant films. Silane coatings are usually more expensive than their organic counterparts and must be kepi dry before application,... 

Solidification/stabilization processes play a more important role since, in the near future, only inert or stabilized wastes should be landfilled. Solidification/stabilization process means binding the hazardous material in the hydraulic binders for safe landfilling or use in civil engineering purposes. Various types of cement, inorganic binders and pozzolanas (e.g., coal burning fly ash, lime, blast-furnace slag and similar materials) are mostly used as the...

Organic compounds are less resistant to nuclear radiation, and conventional oils and greases are therefore inferior to molybdenum disulphide in this respect. The same applies to the organic polymers which are often used as binders in bonded films. Inorganic binders should be used in preference to organic binders where whole-life radiation doses higher than lO R are predicted. 

There are indications that polymeric binders may protect films to some extent against oxidation by moist air in storage. A few tests on a fully-burnished soft film with an inorganic binder also showed no deterioration during extended storage in air at 70% relative humidity and 60°C. This gives some confirmation to the concept that in a fully-burnished film the exposed surface consists almost entirely of inert basal planes, and is therefore more resistant to chemical attack.

Zinc dust coatings are utilized in large quantities for the protection of structural steel, also including underwater steel construction and ship building [5.56]. Zinc dust is used in organic and inorganic binder systems (alkali silicates, ethyl silicates) [5.56, 5.105]. 

BET surface areas of the HISIV 1(X)0 and HISIV 3(X)0 zeolites were 585 and 419 m /g, respectively. In order to determine proper type of inorganic binder, equilibrium loading amount of toluene into zeolite impregnated paper was measured HISIV 1000 zeolite showed that zeolite adhered by silica sol adsorbed more toluene than zeolite adhered by alumina sol at low partial pressure as shown in Figure 2. Thus silica sol was used as a binder for binding zeolite between fibers of the ceramic paper. 

Figures 1(a) to (c) represent SEM images of (a) bare, (b) silica-impregnated and (c) titanium silicate-impregnated ceramic sheets. In the bare ceramic sheet, there is large open volume between ceramic fibers and the adhesion between ceramic fibers was induced by the silica sol, an inorganic binder. On the other hand, in the silica or titanium silicate-impregnated ceramic sheets, there was no free volume between ceramic fibers. In the two cases, the open volume was fulfilled 1 the impregnated silica or titanium silicate adsorbents. It was interesting that many microcracks were shown in the titanium silicate...

Granular refractories (castables, mouldables, mortars, etc.) serve for the construction of monolithic kiln and furnace linings, for hot and cold repairs, as mortars for the joining of bricks, etc. Essentially, they are mixtures of refractory granular materials with inorganic binders which provide strengthening in situ . 

Other organic and inorganic binders have also been tested. Polymerization of styrene or methyl methacrylate in cancrinite-monomer mixtures produces hard, rugged products. Sodium silicate solution mixed with powdered silica also appears to be an effective binder for the cancrinite. 

As an example of a detonating firework composition the following may be given phosphorus sulphide is mixed with an oxtdan and an inorganic binder consisting of magnesium oxide and an alum. 

Organic or inorganic binders are used to fix the silica layer on the surface of a glass plate. Furthermore, the layer generally contains an inorganic fluorescence indicator...
