Mica flake in fine medium coarse size use in drilling electronics paint rubber industry

Mica flake is prepared from grinding and breaking of naturally occurring muscovite mica (complex group of aluminium silicate mineral) scrap or waste by dry ground process. The production is economically carried out in high speed rotary hammer mills or pulverisers. Meticulous care and precaution is taken to avoid deterioration of its natural brilliance, colour and properties.

Mica Flakes grades and particle size

There are three types of Mica Flakes which are generally used for specific purposes :

Coarse Mica Flakes (Grade “C”) : Suitably used for normal sealing and bridging of the openings. Particle size is 2 – 20 Mesh (9.50 – 0.850 mm). Apparent bulk density is 0.17 gm/cc.

Medium Mica Flakes (Grade “M”) : Suitably used to combat mild circulation loss in porous formations. Particle size is 6 – 40

Mesh (3.35 – 0.425 mm).  Apparent bulk density is 0.18 gm/cc.

Fine Mica Flakes (Grade “F”) : Suitably used when a sealing agent is needed to be small enough to allow the mud to pass through a shaker screen without interfering with the operations. Particle size is 20 – 100 Mesh (0.850 – 0.150 mm). Apparent bulk density is 0.20 gm/cc.

Mica Flakes are reputedly used in water-based and oil-based drilling  operations  as  an  effective  mud  additive  chemical  to prevent loss of circulation and seepage. The platy structure of Mica facilitates the overlapping of particles to form a layer or wall and acts as a sealant that bridges the openings. The use of Mica helps to seal porous formations and contributes to regain circulation keeping the solids in suspension.

Characteristics of Mica Flakes

Mica is an important LCMs (Lost Circulation Materials) and mica mixed drilling muds show many performance advantages :

       Cost effective and inexpensive

       High heat and temperature endurance

       Excellent borehole stability

       Resistance to downhole corrosion

Physical and chemical specification of Mica

Safety and handing of Mica

Is non-toxic and non-hazardous to skin contact. Use of mask is recommended  for  long term  exposure to high concentration  of mica dust.

Other uses of Mica

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 Flakes

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.
