EP-1309398-B1 chemical patent summary.Perlite is a naturally occurring volcanic rock formed from siliceous lava or ash. Due to rapid cooling, the lava or ash solidifies into a glass-like rock. Over tens of thousands of years, surface and ground water infiltrates the rock and becomes trapped in the glass structure. When heated at temperatures from 750 to 1,250°C, perlite expands ...

An expanded perlite product having a controlled particle size distribution wherein the ratio of the standard deviation of particle size distribution to the median particle size is less than 0.63 and wherein the median particle size is less than 50 microns. 2. The expanded perlite product of claim 1, wherein the ratio of the standard deviation ...Perlite filter aids are produced by controlled milling and size classification of expanded perlite. A prerequisite for the production of good quality perlite filter aids is a high-quality perlite ore. Most perlite ores are not satisfactory for filter aid production. Perlite filter aids are often touted for their 25% more filtering capacity.

Once exposed to rapid, controlled heating, the expanded perlite takes on a foam-like structure of microscopic glass bubbles that contain a multi-cellular core. These clusters of glass bubbles have many unique qualities that offer great advantages in industrial uses. In addition to being lightweight, Ryolex is non-toxic, non-combustible ...Classifications.

Expanded perlite is produced by perlite expansion furnace, it is a kind of white granular material with a honeycomb structure inside which is made by preheating and instantaneous high temperature roasting. ... The ore particles are controlled by the force in the direction of the furnace chamber. The force of the ore can be summarized into two ...Insulation. When perlite ore is expanded by exposure to rapid, controlled heating, it grows up to 20 times its original volume; this transformation drastically reduce the heat transmission through masonry walls and makes the expanded perlite an excellent thermal and sound insulators, it is also used in paints and gypsum blends as an improver.

Expanded perlite waste was used as a quartz sand replacement in conventional AAC mixtures at 5%, 10%, 20%, 30% and 40% by weight. Results show that use of expanded perlite waste in AAC caused a unit weight decrease in the produced AAC, it is connected with the changes in the properties of AAC.Perlite as a Sludge Absorbent. When perlite ore is expanded by exposure to controlled heating, it grows up to 20 times its original volume and takes on a foam-like cellular internal structure – essentially clusters of microscopic glass bubbles. Fine grades of perlite are mostly broken portions of these clusters, exhibiting a very large ...

Perlite is used in the silviculture industry, and for starting row crops such as hops, and in seed production requiring controlled conditions. It is used extensively for growing tomatoes, cucumbers, peppers, figs ...

When perlite ore is expanded by exposure to rapid, controlled heating, it grows up to 20 times its original volume and takes on a foam-like cellular internal structure — essentially clusters of microscopic glass bubbles. (For a detailed explanation of perlite expansion, see: Why Perlite Works).Growing Media Expanded Perlite In Farm Our well-equipped facilities and superb good quality control throughout all stages of manufacturing enables us to guarantee total buyer gratification for Growing Media Expanded Perlite In Farm, Zeolite Granular, Clinoptilolite Zeolite, Agricultural Zeolite, …

JP-2004506581-A chemical patent summary.The insulation of LNG tanks with expanded perlite is a unique and specific job. To carry out projects of this magnitude, the expansion of the mineral must be performed on site and installation inside the tank must be executed at the same time.. Due to the large volume and dimensions of the facilities, the expanded mineral that is inserted into the tank must be compacted in layers to minimise ...

When perlite ore is expanded or "popped" by rapid, controlled heating, it expands up to 15 times its original volume and takes on a foam-like cellular appearance – essentially clusters of microscopic glass bubbles, creating a porous structure.

Expanded perlite can be manufactured to weigh as little as 2 pounds per cubic foot (32kg/m 3) making it adaptable for numerous applications. Since perlite is a form of natural glass, it is classified as chemically inert and has a pH of approximately 7. Typical Physical Characterictics of Perlite . Color:Expanded Perlite - China Factory, Suppliers, Manufacturers Together with the "Client-Oriented" enterprise philosophy, a arduous good quality control technique, sophisticated producing equipment and a sturdy R&D staff, we generally offer superior quality merchandise, superb solutions and aggressive rates for Expanded Perlite, Zeolite Water ...

Expanded perlite products having controlled particle size distribution, methods of producing the expanded perlite products, and methods of use thereof are provided. The expanded perlite product has, for example, a low ratio of standard deviation of particle size distribution to median particle size (for example, less than 0.63) and low median particle size (for example, less than 50 microns).No chemical incompatibilities reported. When heated to a sufficiently high temperature, it expands to between four and twenty times its original volume as its 2-6% by weight of loosely bound water boils away. When quickly heated to above 1600 degrees F, pops like popcorn as its water vaporizes. Expanded perlite is a fluffy, white particulate.
