Optical polyrite - abrasive powder, consisting of several crushed natural elements. Each powder particle has sharp hard edges, which determines the ability to mechanically remove thin layers of other materials.
Description and properties of polyrite
Each crystal grain of the powder is a solid solution of cerium dioxide СеО2. In addition to cerium, the composition of the substance includes:
- lanthanum;
- calcium;
- silicon;
- praseodymium;
- neodymium.
Fine powder fraction - particles have a size of 0.8 to 1.5 microns.
The substance is fireproof, non-flammable and non-toxic. Possesses radioactivity, but insignificant, and does not affect the general background radiation. Crystals vary in color from yellow to brown.
Inhalation of fine powder and contact with the skin causes dryness, and contact with eyes causes redness. It is necessary to protect the respiratory system, eyes and skin from direct contact with the substance.
Receiving
To obtain polyrite according to TU 48 4 244 87 in high-temperature furnaces, raw materials are fired - dioxides of rare-earth chemical elements. Then the components are mechanically crushed and mixed in certain proportions. The finished product is packaged in soft waterproof packaging.
Application in industry and everyday life
Already by the name of the product, you can understand its main purpose - polishing materials, including optical lenses. In addition to glass, polyrite is used for abrasive processing:
- jewelry;
- mirrors;
- finishing materials;
- automotive optics;
- electronics parts.
Abrasive treatment removes small scratches and chips of a certain depth from surfaces by removing a thin layer of the base material. It is not difficult to buy optical polyrite - the product is offered by online stores of chemical reagents https://www.umeks.ru/catalog/oksidy/oksidy-redkozemelnykh-metallov/polirit-opticheskiy-tu-48-4-244-87/.
Storage
The product should be stored in tightly closed packaging in dry, ventilated warehouses. It is necessary to protect the substance from sunlight and moisture ingress, since moistening the powder leads to the formation of lumps and a decrease in consumer properties. If dust is generated, turn on the exhaust ventilation. The container should be multilayer made of paper, polyethylene and polypropylene. Powder that gets on the skin is washed off with plain water. The use of a respirator and side-overlapping goggles reliably protects the lungs and eyes from the ingress of small particles.
