Nhanganyaya pfupi nezve natural mica

Natural mica ishoko rakajairwa rezvicherwa zvemhuri ye mica, uye iri silicate ine yakaturikidzana chimiro che potassium, aluminium, magnesium, iron, lithium nedzimwe simbi, kusanganisira biotite, phlogopite, muscovite, lepidolite, sericite, green mica, uye iron lithium Mica uye zvichingodaro. Harisi iro zita rerumwe rudzi rwedombo, asi iro zita rakajairika remica group minerals. Iyo silicate ine layered chimiro che potassium, aluminium, magnesium, iron, lithium uye mamwe masimbi. Zvicherwa zvakasiyana zvine zvinhu zvakasiyana uye nzira dzekugadzira. Kunewo misiyano mishoma, saka pane zvimwe zvakasiyana muchitarisiko chavo, ruvara, uye hunhu hwemukati.

Mica iminerari isiri-metallic, ine zvinhu zvakasiyana-siyana, kunyanya kusanganisira SiO 2, zvinyorwa zvinowanzoita 49%, uye zvinyorwa zveAl 2 O 3 zvinenge 30%. Iine elasticity yakanaka uye kuoma. Insulation, yakakwirira tembiricha kuramba, asidhi uye alkali kuramba, corrosion resistance, yakasimba adhesion uye humwe hunhu, chinhu chinowedzera chakanakisa. Inoshandiswa zvakanyanya mumidziyo yemagetsi, welding tsvimbo, rabha, mapurasitiki, papermaking, pendi, machira, pigment, ceramics, cosmetics, zvitsva zvekuvaka uye mamwe maindasitiri ane huwandu hwakawanda hwekushandisa. Nekuenderera mberi kwekusimudzira kwesainzi uye tekinoroji, vanhu vakavhura nzvimbo nyowani dzekushandisa.

Hunhu hwayo uye chimiro chikuru chemakemikari: Muscovite makristasi ane hexagonal mahwendefa uye makoramu, iyo yakabatana nzvimbo yakati sandara, uye akaunganidzwa maflakes kana mazero, saka inonzi yakatsemuka mica. Natural mica ichena, yakajeka uye inopenya, uye ine yakachena manyorerwo uye isina mavara. Mica ine mabhenefiti epamusoro tembiricha kuramba (kusvika 1200 ℃ kana kumusoro), yakakwirira resistivity (1000 times yakakwirira), yakawanda acid uye alkali kuramba, pachena, kupatsanurwa uye elasticity. Iyo yekugadzira mica insulating sheet ye spacecraft. Izvo zvakakosha zvekushandisa senge synthetic mica insulating sheets yekutarisisa setiraiti uye synthetic mica polarized sheets kune radar phase shifters zvakare ine yakanaka tarisiro yekushandisa muminda yekurapa neyehutano.

Seyakajairwa akaturikidzana chimiro aluminosilicate yechisikigo chicherwa, mica ine yakakosha inooneka yekufambisa mwenje uye ultraviolet shielding zvimiro, uye ine zvakanakira zvekukwirisa magetsi ekudzivirira, asidhi uye alkali kuramba, uye yakanyanya kugadzikana tembiricha. Icho chinoshanduka uye chiri pachena chigadzirwa chemagetsi mune ramangwana. Ideal material muminda yakadai se. Nekudaro, iyo goho rakaderera uye mutengo wakakwira wemica yakasikwa inodzikamisa zvakanyanya kushandiswa kwayo.
