Ukuminyana komthofu: ukuhlaziywa kwezakhiwo zomzimba kanye nezicelo
Umthofu uyinsimbi enezinto ezibonakalayo eziyingqayizivele futhi usetshenziswa ezinhlobonhlobo zezinhlelo zokusebenza zezimboni. Kulesi sihloko, sizobheka ngokujulile ukuminyana komthofu, sihlaziye ukubaluleka kwawo ezinhlobonhlobo zezicelo futhi sichaze ukuthi kungani kubaluleke kakhulu embonini yamakhemikhali.
Ukuminyana Komthofu kanye Nezakhiwo zawo Zomzimba
Ukuminyana komthofu kubhekisela esilinganisweni somthamo weyunithi ngayinye, enenani elithile elingu-11.34 g/cm3. Lesi sakhiwo sokuminyana okuphezulu senza ukuhola kube into ebaluleke kakhulu ezinhlelweni eziningi. Ukuminyana komthofu kungaphezu nje kwenani lezinombolo, kubonisa izici ezibonakalayo ezibalulekile zomthofu njengesisindo sawo esiphezulu, ukumelana nokugqwala okuhle kanye nephuzu elincibilikayo eliphansi (327.5°C).
Ukuminyana komthofu ekusetshenzisweni kwezimboni
Ngenxa yokuminyana okuphezulu komthofu, usetshenziswa kabanzi embonini ekwenzeni imikhiqizo edinga izinto ezisindayo. Isibonelo, emkhakheni wokuvikelwa kwemisebe, ukuminyana okuphezulu komthofu kuwenza ube yimpahla evikelayo efanelekile, evimbela ngokuphumelelayo ukungena kwama-X ray kanye nemisebe ye-gamma. Ekwenziweni kwebhethri, amabhethri e-lead-acid asebenzisa ithuba lokuminyana okuphezulu komthofu kanye nezakhiwo ze-electrochemical ukuze anikeze indawo yokugcina amandla ethembekile.
Ukuminyana komthofu kuyasetshenziswa nasezimbonini zokwakha nezamapayipi amanzi. Amapayipi omthofu ake asetshenziswa kabanzi ezinhlelweni zokusabalalisa amanzi ngenxa yokuminyana kwawo kanye nezindawo ezimelana nokugqwala. Njengoba ukuqwashisa ngemvelo kuye kwanda, kancane kancane amapayipi omthofu athathelwa indawo izinto eziphephile.
Umthelela Wezemvelo Wokuminyana komthofu
Nakuba ukuminyana komthofu kunikeza izinzuzo zokusetshenziswa kwawo ezinhlotsheni eziningi, ukuminyana komthofu nakho kusho ukuthi uyingozi emvelweni. Imfucumfucu enomthofu ophakeme kakhulu, uma ingaphathwa ngendlela efanele, ingaholela ekungcolisweni kwensimbi esindayo yemithombo yenhlabathi namanzi, okungase kube nomthelela emvelweni nempilo yabantu. Ngakho-ke, ukuqonda ukuminyana kanye nezakhiwo ezihambisanayo zomthofu kubalulekile ekuthuthukisweni kokuphathwa kwemfucuza okufanelekile kanye nezindlela zokugaywa kabusha.
Isiphetho
Ukuminyana komthofu akunqumi kuphela izakhiwo zawo ezibonakalayo, kodwa futhi kuthinta kakhulu ukusetshenziswa kwawo embonini nomthelela wemvelo. Ukuqonda ukuminyana komthofu lapho kukhethwa futhi kusetshenziswa izinto ezisetshenziswayo zomthofu kungasiza ekwandiseni idizayini yomkhiqizo nokusebenzisa kuyilapho kunciphisa umthelela wawo omubi kwezemvelo. Ngakho-ke ukuminyana komthofu kuyisici esibalulekile okufanele sicatshangelwe ngokucophelela kukho kokubili ukukhiqizwa kwezimboni nokuphathwa kwemvelo.
