Ithute hore na mica board ea insulating e entsoe ka eng

Karolo e ka sehloohong ea insulating thepa mica boto ke mica. Mica ke minerale e etsang mafika e nang le sebopeho sa kristale se nang le mahlakore a mahlano. Litšobotsi ke ho ts’oara, ho hanyetsa mocheso o phahameng, ‘me sericite e sebelisoa haholo indastering, e sebelisoang haholo ho koahela, ho penta, ho kenya motlakase le liindasteri tse ling.

Mica ke lentsoe le akaretsang la liminerale tsa sehlopha sa mica. Ke aluminosilicate ea tšepe e kang potasiamo, aluminium, magnesium, tšepe le lithium. Kaofela ke meaho e nang le layered le litsamaiso tsa monoclinic. Likristale li ka sebopeho sa li-flakes kapa lipoleiti tsa pseudo-hexagonal, ka linako tse ling li le li-columnar.

The layered cleavage e phethehile haholo, e na le khanya ea khalase, ‘me lakane e na le elasticity. Lenane la refractive la mica le eketseha ka tsela e ts’oanang le ho eketseha ha tšepe, ‘me le ka tloha ho li-protrusions tse tlaase ho ea ho tse bohareng tse ntle. Mofuta o se nang tšepe ha o na ‘mala ka har’a li-flakes. Ha tšepe e phahame, ‘mala o lefifi, le pleochroism le ho monya lia eketseha.

Mica e na le lintho tse ngata tsa ‘mele le tsa lik’hemik’hale, tse kang ho hanyetsa mocheso o phahameng, ho thibela mocheso, ho tiea, joalo-joalo, kahoo mica board ea eona e sebelisoang haholo e le lisebelisoa tsa ho kenya lisebelisoa tsa motlakase, e entsoe ka mica. Boto ea mica e phethiloeng ha e sebelisoe feela ho kenya motlakase, empa hape e sebelisoa haholo indastering ea lik’hemik’hale joalo ka thepa ea moaho, polasetiki le rabara.

Muscovite e sebelisoa haholo indastering, e lateloa ke phlogopite, e sebelisoang haholo liindastering tsa lik’hemik’hale tse kang indasteri ea thepa ea mohaho, indasteri ea ho loantša mollo, moemeli oa ho tima mollo, molamu oa ho tjheseletsa, polasetiki, ho kenya motlakase, ho etsa pampiri, pampiri ea asphalt, rabara, li-pigments tsa pearlescent, etc.

Boto ea Mica Tlas’a maemo a tloaelehileng, litaba tsa mica tsa boto ea mica li fihla hoo e ka bang 90%, ‘me e’ ngoe ea 10% hangata ke sekhomaretsi le likhomaretsi tse ling. Boto e thata ea mica eo re e hlahisang e ka mamella mocheso oa likhato tse 500 tsa Celsius sebakeng sa nako e telele se tloaelehileng sa ho sebetsa, ‘me se ka mamella mocheso o phahameng oa likhato tse 850 tsa Celsius ka nako e khutšoanyane;

Ho feta moo, phlogopite ea rona e ka sebetsa sebakeng se tloaelehileng sa likhato tse 1000 tsa Celsius, ‘me e tumme haholo hobane ho hanyetsa ha eona ho senyeha ho har’a lihlahisoa *.
