I-Platinum - izakhiwo zensimbi ehloniphekile

Ubucwebe busebenzisa izinto ezihlukahlukene. Enye yazo iplatinum - izakhiwo zensimbi eyigugu zenza imikhiqizo eyenziwe ngayo ibe yigugu kakhulu. Iplatinamu iyinsimbi eyinsimbi eyivelakancane etholakala oqweqweni lomhlaba, kokubili omdabu kanye ne-ore, kanye naku-alloy ene-iridium. Ngaphezu kwalokho, i-platinum ingambiwa endaweni ezungezile njengokungcola kwensimbi yethusi ne-nickel. Ungathenga ubucwebe bePlatinor ngokuchofoza isixhumanisi.

Yini iplatinum

Lena insimbi eyigugu embiwa eNingizimu Afrika, e-Ethiopia, eColombia, eZimbabwe, eCanada, e-Urals nase-USA. Iza ngesimo sezigaxa noma okusanhlamvu. Ngokuvamile ngaphezu kwalokho aqukethe insimbi nezinye izinsimbi zeqembu leplatinamu. Kubuciko bobucwebe, iplatinamu ithathwa njengensimbi ehlonipheke kakhulu, ebaluleke kakhulu kunegolide elidumile nelaziwa kakhulu. Inombala omhlophe omsulwa, wemvelo. Ukukhiqizwa kobucwebe be-platinum kudinga ukusetshenziswa kwe-95% yale nsimbi.

Iplatinamu isinda kakhulu kunegolide futhi iyakwazi ukumelana nokulimala kwemishini nezinhlobo ezahlukene zamakhemikhali. Kuyimpahla eqinile, elwa nokungezwani nomzimba okuthi, uma yengezwe kwezinye izinsimbi eziyigugu, ikhulise ukuqina kwayo futhi ithuthukise kakhulu ukubukeka kwayo kobuhle, kodwa futhi inyuse intengo yazo. I-Platinum - izakhiwo zensimbi ehloniphekile kanye nezinzuzo zayo

Ukukhiqizwa kobucwebe be-platinum kuhlukile ekukhiqizeni ubucwebe be-platinum. Indawo ephakeme kakhulu yokuncibilika yale nsimbi eyigugu, efinyelela ku-1768 degrees Celsius, idinga ukusetshenziswa kwamathuluzi afanelekile enqubweni yokubunjwa kobucwebe, kanye nezibunjwa ezilungiselelwe ngokukhethekile.

Kuyaphawuleka ukuthi ukukhiqizwa kobucwebe beplatinamu kuyinkimbinkimbi futhi kudla isikhathi ngoba kuyinto enzima ukusebenza nayo futhi idinga ukusetshenziswa kwamakhemikhali amaningi. Inzuzo enkulu yale nsimbi eyigugu okukhulunywe ngayo ngenhla ukumelana kwayo nokungcolisa, ukonakala nokulahlekelwa umbala wangempela, ikakhulukazi lapho ivezwa amakhemikhali asekhaya anokhahlo noma izimonyo ezisetshenziselwa ukunakekelwa komzimba.



Ngemva kwamashumi ambalwa eminyaka, ubucwebe be-platinum bumbozwe ngendwangu encane kakhulu, ecishe ingabonakali, enikeza ukubukeka okuhle. I-Platinum, esetshenziselwa ubucwebe, ingasetshenziswa njengendawo yokubeka amadayimane namanye amatshe ayigugu. Ngenxa yombala wayo omhlophe, ivame ukudidaniswa negolide elimhlophe ngabantu abangazi kahle ngezakhiwo zezinsimbi eziyigugu. Ukusetshenziswa kweplatinamu kubucwebe neminye imikhiqizo. I-Platinum iphinde isetshenziswe embonini ye-electronics njengoba isetshenziselwa ukwakhiwa kwezinto zokulinganisa, okuhlanganisa ama-electrode. Ama-resistors okulinganisa izinga lokushisa kanye nama-thermocouples nawo enziwe ngeplatinamu.

Izinzuzo zePlatinum

I-Platinum iyigugu ngenxa yezakhiwo zayo ezinhle kakhulu zemishini, ezivumela ukuthi imelane nemithwalo ephezulu yomzimba. Imikhiqizo eyenziwe ngensimbi eyigugu okukhulunywe ngayo ngenhla igcina isimo sayo naphezu kwengcindezi enamandla kuyo. Ukusetshenziswa kweplatinamu enqubweni efana nokwenza ubucwebe kuya kuvame kakhulu ngenxa yokuqina kwempahla kanye nezindleko ezikhulayo. Kodwa-ke, inkinga ebalulekile ukubunjwa okulungile kobucwebe obuvela kule nsimbi.

Le nqubo idinga ukusetshenziswa kwemishini efanele engakhiqiza amazinga okushisa aphezulu kakhulu. Kuyafaneleka ukusebenzisa usizo lwezinkampani ezinjengezethu, inkonzo yazo ephambili iwukuphonsa ubucwebe. Ngenxa yokucubungula okuyinkimbinkimbi nokuthatha isikhathi kweplatinamu, ukukhiqizwa kobucwebe obusuka kule nsimbi kufanele kunikezwe kuphela izimboni zobucwebe ezihlonishwayo ezisebenza ngokukhethekile ngezinsizakalo ezifana nokukhiqizwa kobucwebe beplatinamu.
