Uhlolojikelele

Ngengozi eyengeziwe ebangelwa ibhethri ye-lithium-ion eyenzekayo, Abantu bakhathazeke kakhulu ngokubaleka kwebhethri okushisayo, njengoba ukubaleka okushisayo okwenzeka kuseli elilodwa kungase kusabalalise ukushisa kwamanye amaseli, okuholela ekuvaleni kwalo lonke uhlelo lwebhethri.

Ngokwesiko sizobangela ukubaleka okushisayo ngokushisisa, ukuphina noma ukushaja ngokweqile ngesikhathi sokuhlolwa. Kodwa-ke, lezi zindlela azikwazi ukulawula ukuphuma okushisayo kuseli elishiwo, futhi ngeke zisetshenziswe kalula phakathi nokuhlolwa kwezinhlelo zebhethri. Muva nje abantu baqala indlela entsha yokuqalisa ukugijima okushisayo. Ukuhlolwa kokusabalalisa ku-IEC 62619: 2022 kuyisibonelo, futhi kulinganiselwa ukuthi le ndlela izosetshenziswa kabanzi esikhathini esizayo. Le ndatshana ingeyokwethula ezinye izindlela ezintsha ezisacwaningwayo.

I-Laser Radiation:

Imisebe ye-laser ukushisa indawo encane ene-laser pulse yamandla aphezulu. Ukushisa kuzoqhutshwa ngaphakathi kwempahla. Imisebe ye-laser isetshenziswa kabanzi ezindaweni zokucubungula izinto, njengokushisela, ukuxhuma nokusika. Ngokuvamile kunezinhlobo ze-laser kanje:

• CO₂laser: carbon dioxide molecular gas laser
• I-Laser Semiconductor: I-Diode laser eyenziwe ngama-GaAs noma i-CdS
• I-LAG laser: I-sodium laser eyenziwe nge-yttrium aluminium garnet
• I-Optical fiber: i-laser eyenziwe nge-glass fibre ene-elementi yomhlaba eyivelakancane

Abanye abacwaningi basebenzisa i-laser engu-40W, ubude begagasi obungu-1000nm kanye nobubanzi obungu-1mm ukuze bahlole kumaseli ahlukene.

Ukuba ne-CT scan kuseli elingacushiwe, kungatholwa ukuthi alikho ithonya lesakhiwo ngaphandle kwembobo engaphezulu. Kusho ukuthi i-laser iyaqondisa, futhi inamandla amakhulu, futhi indawo yokushisisa inembile. Ngakho-ke i-laser iyindlela enhle yokuhlola. Singakwazi ukulawula okuguquguqukayo, futhi sibale amandla okufaka nawokukhiphayo ngokunembile. Okwamanje i-laser inezinzuzo zokushisisa nokuphina, njengokushisisa okusheshayo, nokulawuleka kakhudlwana. I-Laser inezinzuzo eziningi ezifana nalezi:

• Ingaqalisa ukuphuma okushisayo futhi ngeke ishise amaseli omakhelwane. Lokhu kuhle ekusebenzeni kokuxhumana okushisayo

• Kungavusa ukushoda kwangaphakathi

• Ingafaka amandla amancane nokushisa ngesikhathi esifushane ukuze iqalise ukuphuma kwe-thermal, okwenza ukuhlolwa kulawuleke kahle.

Impendulo esuka ku Thermite:

Ukusabela kwe-thermite ukwenza i-Aluminiyamu isabelane ne-metallic oxide kumazinga okushisa aphezulu, futhi i-aluminium izodlulisela ku-aluminium oxide. Njengoba i-enthalpy yokwakheka kwe-aluminium oxide iphansi kakhulu (-1645kJ/mol), ngakho-ke izokhiqiza ukushisa okukhulu. I-thermite iyatholakala, futhi ifomula ehlukile ingakhiqiza inani elihlukile lokushisa. Ngakho-ke abacwaningi baqala ukuhlola ngesikhwama esingu-10Ah esine-thermite.

I-Thermite ingakwazi ukucupha kalula ukuphuma kwe-thermal, kodwa okokufaka okushisayo akulula ukulawula. Abacwaningi bafuna ukuklama i-reactor eshisayo evaliwe futhi ekwazi ukugxilisa ukushisa.

I-Quartz Lamp enamandla amakhulu:

Ithiyori: Beka isibani sequartz samandla aphezulu ngaphansi kweseli, bese uhlukanisa iseli nesibani ngepuleti. Ipuleti lidinga ukubhobozwa ngembobo, ukuze kuqinisekiswe ukuziphatha kwamandla.

Ukuhlola kubonisa ukuthi idinga amandla aphezulu kakhulu kanye nesikhathi eside ukuze iqalise ukubaleka kwe-thermal, futhi i-thermal ihlukaniswa ngokulinganayo. Isizathu singaba ukuthi ukukhanya kwe-quartz akukona ukukhanya okuqondisayo, futhi ukulahlekelwa ukushisa kakhulu kukwenza kungakwazi ukubangela ukubaleka okushisayo ngokunembile. Okwamanje okokufaka kwamandla akunembile. Uhlolo olufanele lwe-thermal runnaway ukuhlola ukulawula amandla acuphayo kanye nevelu yokokufaka engaphezulu ephansi, ukwehlisa umthelela womphumela wokuhlola. Ngakho-ke singafinyelela isiphetho sokuthi isibani se-quartz asisebenzi okwamanje.

Isiphetho:

Uma kuqhathaniswa nendlela evamile yokubangela ukubaleka kweseli okushisayo (njengokushisa, ukushajwa ngokweqile kanye nokungena), ukusakazwa nge-laser kuyindlela ephumelela kakhulu, ngendawo yokushisisa encane, amandla okokufaka aphansi kanye nesikhathi esifushane sokucupha. Lokhu kunikelwe ekufakweni kwamandla asebenzayo okuphezulu endaweni elinganiselwe. Le ndlela yethulwe ngabe-IEC. Singalindela ukuthi amazwe amaningi azoyicabangela le ndlela. Kodwa-ke iphakamisa isidingo esikhulu kumadivayisi we-laser. Idinga umthombo we-laser ofanelekile kanye namadivayisi avikela imisebe. Okwamanje azikho izimo ezanele zokuhlolwa kokubaleka okushisayo, le ndlela isadingeka ukuqinisekiswa.
