Ilitye Talc ne iimpawu ezizodwa

Phakathi minerals amaninzi zifumaneka propati ebezifunwa kakhulu kungekuphela kushishino, kodwa amayeza kunye zokuthambisa. Ezi ziquka talc. Eli litye akwaziwa njenge ngezimbiwa, ibe ngumgubo abantwana.

Emangalisayo, kodwa ngokwesimo oko mhlawumbi yesibini zixhaphakileyo emva ematyeni zwi. Kufuneka kuqatshelwe ukuba talcum - ilitye kuphela lidityaniswe-olungisiweyo iintlobo, iqheleke kakhulu ngokuba soapstone.

umbala wayo kuyahluka luhlaza qwa, kungakhathaliseki imibala ubonakala ukuba Ndileka yayo ubaxo. Yena ithambe kakhulu ukuba bachukumise aze anike uluvo lwe lubricity. Ngokutsho Mohs yokuqaqadeka ziphononongwa njenge "1" (ubuncinane).

Njengoko sisazi ukuba - ukuba ngumgubo olunamafutha erhabaxa, leyo ibizwa ngokuba "talc". Eli litye zisasazwa kuba iimeko komhlaba yayo ukubunjwa standard ngokufanelekileyo.

Ukuthetha ngokwenzululwazi, igama layo chemical - wemagniziyam ezimuncu metasilicate H2Mg3 (SiO3) 4. Crystallization senzeka rhombic yayo okanye uhlobo monoclinic. Kwindalo, efumaneka igqabi-emile okanye granular namabandla.

Ukusuka kwindawo wejoloji lwembono, talc - ngezimbiwa zesekondari kuye kwasekwa emva inguqu yemichiza bezalyuminievyh silicates wemagniziyam. Ngokufuthi a olukhulu loo ivavanywa amphibole okanye pyroxene.

Amaxesha amaninzi, ngembonakalo kunokuba bedidekile kunye "umzali", njengoko igcina ngokupheleleyo isakhiwo sayo crystalline, ezahlukeneyo kuphela kumafa yemizimba yethu.

Le talc efanayo kakhulu, ogama umfanekiso lowo ephepheni, uxatyiswa ngenxa umbala wayo: mhlophe oko kukuthi, ngakumbi xa izinto imfuno. Kufuneka kuqatshelwe ukuba ishishini lisebenza talc umzuzu nje, umhlaba umgangatho omhle kakhulu.

Andiqondi ukuba le nto zifumaneka kwindalo kuphela ngendlela enye. Kukho ezininzi kweentlobo yayo iyahluka kakhulu kumafa yemizimba yethu kunye neepropati ebonakalayo:

• Minnesotaite (iqulathe ukuya kwi-50% intsimbi).
• Villemseit (kuquka nickel).
• Steatite (nto leyo edla ngokuba wen), ebalasele isakhiwo ashinyeneyo kakhulu aqinileyo.
• Malaga. Ngokungafaniyo kuneyokuqala, kuba kukho ifayibha entle kakhulu.
• talc Noble: uhlobo ilungileyo, apho abamhlophe amanene.

Uninzi talc geni eUnited States. Xa ininzi kakhulu eli hlobo yaphuhliswa eBrazil, eMzantsi Korea, eJapan naseRashiya.

Ngoko usebenzisa njani powder talcum? Eli litye iye isetyenziswe njenge ngumgubo, "spacers" phakathi izinto irabha, njengokuba lokufaka, kwaye ngokubanzi isetyenziswa ngabaqholikazi ukwenza iintlobo ezintsha ngumgubo.

Kuphela nje ifanelekileyo ukuba indalo le mizekelo ilungileyo le hlobo makeup. Hi ndlela leyi, sebenzisa kuphela abathungi abaqeqeshiweyo 'itshokwe', olusekelwe phezu zonke talc efanayo. Ishishini okuhle iintlobo zalo asetyenziswa ekwenziweni insulators zombane.

Hi ndlela leyi, kungakanani talc? Ukuza kuthi ga ngoku, ixabiso yi 1000 Roubaud kwekilogram izinto ukusilwa ezikumgangatho ophezulu nganye.
