What is perlite? & Types of Perlite
Perlite is a generic name given to the natural volcanic rocks that can be found all over the world.
A unique feature of perlite is that its original volume can be expanded up to 35 times when heated to softening point (850 – 1150 ° C). This expansion process occurs through the water in the raw rock. If the perlite ore is heated rapidly at 850 ° C (16000 ° F), water will start to evaporate and cause the softening stone to expand. Small glass-like bubbles form, creating the exceptional lightness and physical properties of expanded perlite. Perlite is a glassy volcanic rock in varying colors ranging from gray to gray, which means pearl stone. In this state the perlite is called RAW PERLITE.
When Raw pearlite is broken down in various dimensions and passing through the sieves at different intervals it is called CLASSIFIED PERLITE.
When the classified perlite is heated at the high temperature and with the flame shock it loses the constituent water. Then grows up to 35 times the grain volume as a result of the explosion. This is called EXPANDED PERLITE.
International organizations operating in the sector
The Perlite Institute Inc., which was founded in the USA in the production of the perlite, the technology and the consumption of the most important countries of the world, it is defined as a solution to the needs of institutional development and it continues its activities with very important and positive contributions that it has realized up to the day.
The reasons for the establishment of the Perlit Institute are summarized as follows:
As there is no known technical knowledge providing contributions to the acceptance of perlite. Acceptable commercial standards and sufficient information in the public opinion, in the case of a superficial praise in the market.
There is a need for a coherent effort and a continuous campaign in the sense of self-help so that the perlite industry. This can not be adequately assessed if it is a promising area, can have a bright future.
It is necessary that the producers, the responsibilities of preparing the specification and the product identification. The research and information requirements of the users and consumers have to be met in an effective and economical way.FAQ - frequently Asked Questions Contact Us TO LEARN MORE!
