Ukuvela Kokushiswa Kwe-Aluminium Thermite: Umbono Womlando

Isingeniso:
Ukushisela i-aluminium thermite, okwaziwa nangokuthi ukushisela i-aluminothermic noma ukushisela i-thermit, kuyindlela ekhethekile yokushisela esebenzisa ukusabela kwamakhemikhali ukukhiqiza ukushisa okukhulu kokuhlanganisa izingxenye ze-aluminium. Lesi sihloko sihlose ukuhlola intuthuko kanye nokuvela kokushisela i-aluminium thermite, siqokomisa izinyathelo ezibalulekile kanye nentuthuko kulo mkhakha.

Iziqalo Zasekuqaleni:
Izimpande zokushisela i-thermite zingalandelelwa emuva ngasekupheleni kwekhulu le-19 lapho usokhemisi waseJalimane uHans Goldschmidt eqala ukuthuthukisa ukusabela kwe-thermite ngo-1893. Ekuqaleni, le nqubo yayisetshenziswa kakhulu ekushiseleni insimbi nensimbi. Kodwa-ke, abacwaningi basheshe baqaphela amandla okushisela i-thermite ye-aluminium, ngenxa yezakhiwo zayo ezilula nezimelana nokugqwala.

Ukushisela i-Thermite eqondene ne-Aluminium:
Ekuqaleni kwekhulu lama-20, kwenziwa imizamo yokuguqula inqubo yokushisela i-thermite ibe yi-aluminium. Abacwaningi bazama ukwakheka okuhlukene kwezingxube ze-thermite ukuze bafinyelele amazinga okushisa adingekayo ukuze kuhlanganiswe i-aluminium. Le mizamo yokuqala yabeka isisekelo sokuthuthukiswa kokushisela i-aluminium thermite.

Intuthuko Ekubunjweni Kwengxube:
Ngokuhamba kwesikhathi, abacwaningi balungisa ukwakheka kwengxube ye-thermite ukuze bathuthukise inqubo yokushisela i-aluminium. Ukwengezwa kwezimpushana zensimbi ezahlukahlukene, njenge-iron oxide ne-aluminium, kwavumela ukulawula okungcono kokusabela kanye nekhwalithi yokushisela ethuthukisiwe. Lokhu kuthuthuka kwenze kwaba nokushisela kwe-aluminium thermite okuthembekile nokusebenzayo.

Isicelo ku-Railway:
Kuvele ukusetshenziswa okubalulekile kokushisela i-aluminium thermite embonini yezitimela. Le nqubo yabonakala isebenza kahle kakhulu ekuhlanganiseni imisele ye-aluminium, inikeza amandla aphezulu nokuqina uma kuqhathaniswa nezindlela zendabuko zokushisela. Ukushisela i-thermite kwaba yindlela ekhethwayo yokuhlanganisa imisele, okuqinisekisa ukusebenza kwesitimela okubushelelezi nokuphephile.

Izimboni Zezindiza Nezimoto:
Njengoba i-aluminium ithola ukuthandwa emikhakheni yezindiza kanye neyezimoto, isidingo samasu okushisela asebenzayo sakhula. Ukushisela i-aluminium thermite kwangena kulezi zimboni ngenxa yekhono layo lokuhlanganisa izingxenye ze-aluminium ngokuphambuka okuncane kanye nezakhiwo ezinhle kakhulu zemishini. Le ndlela idlale indima ebalulekile ekuhlanganisweni kwezakhiwo zezindiza kanye nohlaka lwezimoto.

Intuthuko Yezobuchwepheshe:
Ngokufika kwezinto ezithuthukisiwe kanye nobuchwepheshe bokushisela, ukushisela kwe-aluminium thermite kwathuthukiswa kakhulu. Ukuthuthukiswa kwezimonyo ze-ceramic ezibekwe kusengaphambili kanye nama-exothermic welding kit kwathuthukisa ukunemba kanye nobulula benqubo yokushisela. Lokhu kuthuthuka kwaba negalelo ekwamukelweni kabanzi kokushisela kwe-aluminium thermite ezimbonini ezahlukahlukene.

Izicelo Zanamuhla:
Namuhla, ukushisela i-aluminium thermite kuyaqhubeka nokuthola ukusetshenziswa emikhakheni eyahlukahlukene, okuhlanganisa ezokuthutha, ezokwakha, kanye nezokukhiqiza. Kuvame ukusetshenziselwa ukuhlanganisa amapayipi e-aluminium, ama-conductor kagesi, kanye nezinye izingxenye ze-aluminium. Ukuguquguquka kwale ndlela, ukusebenza kahle kwezindleko, kanye nokusebenza okuthembekile kwenza kube ukukhetha okuthandwayo kwezidingo ezithile zokushisela.
