Talc ibwe nemamwe ehupfumi

Pakati zvicherwa kazhinji kuwana ehupfumi dzakadaro vari mukuru kwokudiwa kwete indasitiri, asiwo mushonga uye zvizoro. Izvi zvinosanganisira talc. ibwe iri Hazvizivikanwi somunhu chicherwa, uye somunhu upfu vana.

Oddly, asi zvakasikwa izvozvo zvichida ndicho chechipiri rakajairika pashure Goldstone matombo. Zvinofanira kucherechedzwa kuti talcum - ibwe chete vakasindimara-grained mhando, zvakawanda anowanzonzi soapstone.

ruvara Its zvichisiyana zvakasvibirira kuti wakachena chena, pasinei ruvara zviri chinozikamwa ayo pearly Sheen. Iye dzakapfavirira chaizvo kuti kubata uye anopa pfungwa lubricity. Maererano Mohs noukukutu hunoyerwa se "1" (Minimum).

Sezvatinoziva kuzviziva - zviri jikichira zvinonyadzisa upfu, unonzi "talc". ibwe iri rinoparadzirwa nokuti ezvinhu ayo inotungamirwa zvemaumbirwo nokururamisira mureza.

Achitaura nesayenzi, zita rayo makemikari - anovava magnesium metasilicate H2Mg3 (SiO3) 4. Crystallization kunoitika panguva rhombic yayo kana monoclinic mhando. Zvakasikwa, kuwanikwa mashizha serin'i kana granular idzodzo.

Kubva Geological nemaonero, talc - mumwe chicherwa yechipiri dzisingadi pashure makemikari kuchinja bezalyuminievyh magnesium silicates. Kazhinji kwakadaro metamorphosis kaviri amphibole kana pyroxene.

Kakawanda, nechitarisiko kunogona kuvhiringidzwa "mubereki", sezvo zvizere anoramba crystalline ayo mamiriro, zvakasiyana chete kwavo makemikari anoumba.

The chaizvo chete talc, ane pikicha iri mupepa, iri aikoshesa nokuda kwayo ruvara: asi akachena ndiko, akanyanya kwokudiwa zvinhu. Zvinofanira kucherechedzwa kuti indasitiri rinoshanda talc chete miniti, zvakanaka chaizvo unhu pasi.

Handifungi kana mashoko aya anowanikwa mune zvakasikwa chete chimiro chimwe. Kune akawanda zvipenyu ayo zvakasiyana-siyana muupenyu hwavo makemikari anoumba uye panyama zvivako:

• Minnesotaite (rine kusvika 50% yesimbi).
• Villemseit (zvinosanganisira nickel).
• Steatite (iyo kazhinji unonzi wakange), ichazivikanwa noku zvikuru gobvu uye rakasimba marongerwo.
• Malaga. Kusiyana nowakautangira, ndiko faibha yakanaka kwazvo.
• Noble talc: yakanakisisa mhando, sezvamakaropafadzwa anokudzwa chena.

Vazhinji talc mined muUnited States. In Mavhoriyamu guru erudzi urwu yakazokudziridzwa muBrazil, South Korea, Japan uye Russia.

Saka sei kushandisa talcum upfu? ibwe iri rave richishandiswa sechinhu upfu, "spacers" pakati rabha zvinhu, sezvinoita filler, uye zvikuru kushandiswa vezvinonhuhwira rokusika mhando itsva upfu.

Chete chinonyanya akakodzera pakusikwa mienzaniso yakanakisisa kuti masikirwo mhando iyi. Zviya, shandisa chete nenyanzvi tailors 'choko', iyo yakavakirwa zvose zvakafanana talc. The indasitiri wakanaka mhando ayo akashandiswa zvaAtemisi magetsi insulators.

Zviya, sei zvakawanda talc? Kusvika panguva mutengo anenge 1000 Roubaud paminiti kilogram yepamusoro milled zvinhu.
