Mica extender and filler uses in drilling, painting and electronic industry
Mica is a general name style of mineral that is similar one another existing in nature with dust. it's light-weight and flexible material that even have layer and powder properties. it's high heat resistance and doesn't conduct electricity. Generally, this material produces with two-way sheet and flake mica. Sheet version cost is therefore low so it's very economy mining material. whereas production method It would like care to get rid of this material thanks to having crystalised properties
It uses as a filler and extender that is stop cracking and create a smoother consistency and improves workability, within the paint business, ground mica is used as a pigment extender that also facilitates suspension due to its light-weight weight and platy morphology. It conjointly reduces checking and chalking, prevents shrinkage and cutting of the paint film. mica conjointly has water resistance properties weathering, and brightens the tone of coloured pigments. It is also employed in the well-drilling industry as an additive to drilling “muds.”
Having extender and filler properties create this items helpful in paint and drilling industry as a reinforce agent. The rubber business uses ground mica as AN inert filler and as a mold lubricator within the manufacture of shaped rubber product, as well as tires.Sheet mineral will use in electronic business the most functions of usages of mica is acts an insulator for all electronic devices. dielectrics in capacitors, decorative panels in lamps and windows, insulation in electrical motors and generator armatures, coil insulation, and magnet and electric switch core insulation. The high thermal resistance permits it to be used as an insulator in varied physical science It conjointly an additive material in cosmetic. Its shiny and glistering look makes it ultimate for toothpaste and cosmetics.
Other properties of Mica
Physical: mineral is translucent, easily split into thin films on its cleavage, optically flat, colorless in thin sheets, elastic and incompressible.
Chemical: it's a compound hydrous salt of metal, that also contains iron, magnesium, potassium, sodium fluorine, metal and conjointly few traces of various different components. it's constant and fully static to the action of water, acids alkalies, typical solvents, bases, and oil. It remains nearly unchanged by part action.
Electrical: Mica has the exclusive combination of uniform insulator steadiness, capacitance stability, huge insulator power, high Q issue and lower power loss, high electrical resistance and coldness constant. it's extremely regarded for its resistances to arc and corona discharge while not inflicting any lasting injury.
Thermal: It's extremely fireplace proof, fireproof, non- inflammable, infusible, and can also resist temperatures of up to one thousand degrees Celsius/1832 degrees physicist. but this relies on the kind and style of mica used. it's wonderful thermal stability, lower heat conductivity, and may be simply exposed to high temperatures while not visible result.
Mechanical: Mica is extremely tough, having high strength, elastic, and beside being versatile. it's immense compression power and may be machined, die-punched, or hand cut.
