Indlela ukufumanisa lexinene ilitye?

Zonke izimbiwa (namatye ilithumele neeminerali) aneempawu ezimbini ezibalulekileyo - ubunzima kunye mninzi. Kwaye ke mninzi ilitye kubalulekile ngengqiqo kuphela pfunaka - ukubala oovimba zezimbiwa.

Ziziphi ezi mpawu?

Kuba nawuphi na umcimbi phantsi loxinano libhekisela ubunzima bahlulwe unit umthamo. Ekubeni ngamatye (ngamanye neeminerali) kufuneka non-uniform Ukwakhiwa kwaye ziquka ubunzima izinto ezahlukeneyo atomic, ubunjalo bomzimba mninzi yabo zinokwahluka kakhulu. Kwakhona amatye konga kuxhomekeke kungekuphela ubungqongqo eziqalelo, izakhi zabo, kodwa ngendlela ngokuqinileyo "wapakisha" kubume lwangaphakathi amasuntswana nezakhiwo.

Study imibuzo kwezimbiwa mninzi ukwenza mineralogy. mninzi ilitye kubalwa ngokwahlula-hlula ubunzima sample nganye iyunithi umthamo wamanzi izimbiwa kwi ubunzima umqulu enye ⁰S-4. Umzekelo, ubunzima isampuli 200 gram. Amanzi kwisixa-mali enye ye-40 grams. Kulo mzekelo, lexinene ilitye iya kulingana ku-5.

Walinganisa lexinene yamatye ngeekhilogram nganye kwimitha cubic, okanye grams ngamnye sentimitha cc.

Indlela yokufumana lexinene ilitye?

Njani, ngoko, oko kumiselwa lexinene ilitye? Inkqubo kakhulu ilula - inobunzima isampuli yokuqala umoya uze emanzini. Ngokutsho umgaqo Archimedes ', umahluko ifunyenwe ingqamana ubunzima amanzi lenkosikazi isampulu. Ingxinano kubalwa ngokwahlula-hlula ubunzima isampuli umoya kule mahluko.

Kuxhomekeka lexinene i izimbiwa singakwazi ukuba abanomoya, alungise, ebhala nzima kunene. Umzekelo, lexinene lenyengane ilitye - 2600 kg / m³. Ukudluliselwa ukukhanya lexinene engadlulanga 2.5 g / cm³, eliphakathi - oko isusela ukusuka 2.5 ukuya ku-4 g / cm³, enzima - 4 ukuya kowe-8 g / cm³. yezimbiwa mninzi in excess-8 g / cc matye nzima kakhulu.

Lexinene amatye

Ukongeza loxinano kunye nezinye iimpawu - izimbiwa lukhuni, GEMS okanye amatye abe licandelo ezibalulekileyo ezifana ubunzima, kulinganiswa ziigrems okanye eqatywe (y neeperile - in grana).

Ukuze siqonde umlinganiselo kweeyunithi ze data, qaphela: 1 eqatywe ingqamana milligrams 200, xa ekupheleni milligrams-50, ngamanye amazwi, 1 eqatywe ilingana obune. GEMS ukuchana Umlinganiselo - kwiindawo ezimbini wokugqibela.

Yizani kwilebhu

Indlela ukulinganisa lexinene kotsalo. amatye elebhu? ifanele khulu le ndlela hydrostatic. Umgaqo yaphakanyiswa yi-nzulu Greek Archimedes kwiinkulungwane ezininzi ezadlulayo. Kakuhle eli umgaqo ndisazi physics esikolweni Kakade ke, yile: umzimba uxakeke ulwelo sinyanzeliswe kuyo ngamandla, nto leyo ilingana ubunzima kulwelo abafudukayo ngokutsho umzimba.

Ngamafutshane, ukuba akuxhome ilitye nolahlo emanzini, ubunzima bayo kuyehla xa kuthelekiswa woqobo kangangoko Umlinganiseli umthamo wamanzi abalahlekelwa nto. Kuyaqondakala ukuba le mali iya kulingana umthamo yayo welitye.

Kanjalo amatye enobunzima wempumelelo emoyeni, yaye emva koko emanzini singakwazi azifumane zonke iinkcukacha ezifunekayo ukuze ukubala.

Zonke - yendalo!

Ngoku makhe ukuba izinto amatye yendalo. Ba, njengokuba usazi, kukho iindidi ezininzi. Ukusuka kwindawo ezenziwayo, naluphi na uhlobo ingaqhuba iye kwenye amaqela amabini - ezisezantsi-amandla okanye amandla.

Izixhobo ze iqela lokuqala kufuneka yobulukhuni liphezulu, yaye zonke, isakhiwo eliphakathi okanye irhabaxa. Urhulumente ekuthiwa nevyvetrennom babe ukufakwa encinane amanzi. Ngamanye (ephantsi-amandla) engxondorheni, njengoko igama lichaza, eyona amandla usezantsi kakhulu. Kwakhona kufuneka iqondo eliphezulu ukufunxeka kwamanzi.

Maxa wambi xa siqaphela iintlobo zamatye ezifunekayo ukumisela yokuqaqadeka yayo. Endle, ngokuba kuhle ukuba yenze ngoncedo t. N. isihlobo Mohs isikali kunye nezinye izixhobo ezikhoyo. Ngenxa yoko lead ngcono inokufana ezinkozo, isiqwenga iglasi, ifayili, ngenaliti intsimbi okanye imela, i mgawuli iglasi eqhelekileyo okanye diamond. Ukuxinana avareji ilitye kubalulekile ekuqinisekiseni uhlobo yakhe. Ukuba sizimisele eli xabiso hlobo ezichongiweyo iliwa ngokubhekisa ezitafileni ezithile.

Thina ukubala lexinene endalo

Ungabala njani imin lexinene isampuli-ilitye? Izixhobo ezifunekayo kule - iseti izikali benemizimba kunye nezakhono yomlinganiselo umthamo isampulu, nokuba imilo ezitenxileyo ezinokwenzeka.

Indlela elula yokwenza oku ngokubeka umlinganiselo lombhobho izidanga malunga nesiqingatha ilitha. Xa isilinda enjalo obegalelwe 200-300 ml amanzi kwaye ubeka isiziba uvavanyo izinto ngamatye.

Umthamo uwonke wamanzi zibekwe isampuli ivunyiwe umlinganiselo wamanzi abafudukayo ngabo. Emva koko, ubunzima ngokwahlula yi umthamo ubalwe avareji ukulungele izinto mninzi.

Kubalulekile Yintoni ukuqwalasela?

Kufuneka kuqatshelwe ukuba le ndlela efanelekileyo kuphela ilitye rock ashinyeneyo kunye nokufunxwa kwamanzi ephantsi (ngaphantsi kwe-2%). Ukuba olu phawu iphezulu (ukuya kwi-5%), isampuli owomileyo ngaphambili ubunzima ekuqaleni mazifakwe kwi zolwelo eliphakathi kufumaneka bantu. Emva koko, ingxinano umiselwa indlela ngasentla. Ukwanda ithathwa ngokupheleleyo ukuba ubunzima ukufakwa kwamanzi liyayeka ukuba zikhule.

amatye misindo (amaninzi lekalika okanye tuff) kufuneka libangela i KHTML ingasebenzi. Kulula ukuphatha - a hacksaw eqhelekileyo ukuba wabona isampuli imilo olifunayo (umz, a cube) kunye kumetwa ubuso ukubala umthamo wayo.

Yenza kube ngokwakho

Xa kungekho mhlaba izidanga lombhobho ezaneleyo ukujonga umlinganiselo wamanzi abafudukayo ngolu hlobo lulandelayo. Kuyo nayiphi na isikhongozelo sisinyithi semilo zezindlu ngezantsi kancinane imingxuma punch ephezulu eludongeni isikhonkwane eqhelekileyo, ke ifakwe kwi bile, nto leyo kwakhona kuveliswa ngokuzimeleyo, ajike ingenisa. Ukunqabiseka isilinda zodongwe yayo eludongeni okanye nantoni na efana.

Ngaloo ndlela, a ehamba piston semitha. Ukuba yunithi isetyenziswa rhoqo, iyavakala ukuba solder ngensimbi umbhobho okanye yobhedu.

Stones, eyenziwe zizandla zabantu

Yonke into ebhalwe apha ngasentla ubhekisela endalo. Kwaye ngoku lixesha lokuba uthethe ngayo zedolophu. Iiplastiki eludongeni, indlela kunye moya. Oku kufuneka luquke iithayile eziphathekayo uphahla neebhloko ukupheyiva, kwakunye nazo zonke iintlobo kwindawo eyimfama, izinyuko neziqalelo itshimini.

Ekuvelisweni phantse zonke ezi yamawa eRashiya nakumazwe aphesheya, esebenzisa imigangatho engqongqo zobugcisa. Bathi elawula zonke iimpawu eziphambili - umgangatho izinto, ubungakanani kunye nemilo cross-lecandelo, iimpawu zomzimba mechanical (kubandakanywa iibhloko mninzi eziphathekayo).

Ezi mfuno zixhomekeke kwiimeko yokusebenza ekujoliswe kunye nezinto ezikhoyo.

ingaba yintoni na ilitye ngumntu?

Eziphathekayo, kwenziwa apho amatye, kunokuba nzima okanye ukukhanya. Wenziwe amatye yakhe ngumntu, wenza ngokupheleleyo eyomeleleyo okanye vuphukuphuku. Regulatory iimpawu avareji bulk ezinoxinano ngamatye ezibuhlazarha mayingabi ngaphezu 1650 kg / m³, kuba corpulent - 2200 kg / m³.

iiyunithi amaziko yi-avareji kwinqanaba ingxinano (yaye, ukongeza, conductivity thermal) zithathwa olusebenzayo (mninzi ukuya ku 1400 kg / m³), phantsi kwemiqathango ethile olusebenzayo (1 400-1 650 kg / m³) kwaye yababuhlungu (mkhulu kwe-1 650 kg / m³). Abaninzi kubo ngoku ezenziwe ngekhonkrithi elula, ingxinano ephantsi (ukuya ku 1800 kg / m³).

eziphathekayo Heavy (kubandakanywa intlabathi) kunye lingonakali eliphezulu kunye nokufunxwa kwamanzi phantsi isetyenziswa ukuvelisa ebhodini okanye amatye zendlela nemàbhula ukupheyiva, njengoko iimeko umsebenzi wabo kakhulu ngaphezu eludongeni.

ilitye yokufakelwa ezahlukeneyo kwemali, nto leyo inokuba isanti zwi (ingqalelo a aggregate omhle) okanye iliwa (aggregate irhabaxa). Umzekelo, uhlalutye ukuxinana ilitye zendalo inokuba nomahluko ngokuxhomekeke iqhezu - fineness. Ukubunjwa yempembelelo aggregate yaye lifikelelekayo lexinene ilitye sokwenziwa.
