Izindlela Zokwehluleka Kwezinto Ezibalulekile Ngaphansi Kwezimo Zokusebenza
I-Pendahuluan
Ukwehluleka kwezinto ezibonakalayo kuyinto ebalulekile okumele ixazululwe ezimbonini ezahlukene, kusukela kwezezimoto nezindiza kuya ekwakhiweni kwemikhumbi. Ukwehluleka kwezinto ezibonakalayo isimo lapho izinto ezibonakalayo zehluleka ukwenza umsebenzi wazo ohlosiwe, okungaholela ezingozini ezibulalayo, ekulahlekelweni kwezimali, ngisho nasekulahlekelweni yimpilo. Lesi sihloko sihlose ukuxoxa ngezindlela ezahlukene zokwehluleka kwezinto ezibonakalayo ngaphansi kwezimo zokusebenza, okuhlanganisa ukwehluleka kokukhathala, ukwehluleka ukugqwala, ukwehluleka ukuguguleka, ukuqhekeka kokucindezeleka, kanye nokwehluleka kwemvelo.
1. Ukukhathala Kwezinto Ezibonakalayo
Ukuqonda Ukukhathala Okubonakalayo
Ukukhathala kwezinto ezibonakalayo kuyindlela yokwehluleka eyenzeka ngenxa yemithwalo ejikelezayo noma ephindaphindwayo esetshenziswa ezintweni ezibonakalayo. Le mithwalo ibangela umonakalo oqongelelekayo, uma ungatholakali, ongaholela ekwahlulekeni kwezinto ezibonakalayo.
Indlela Yokukhathala
Ukukhathala kwezinto ezibonakalayo kwenzeka ngezigaba ezintathu eziyinhloko:
1. Ukuqaliswa Kokuqhekeka: Ukuqhekeka okuncane kuqala ukwakheka ezindaweni ezixinene kakhulu, njengasemaphethelweni emigodi, izinguquko ezingxenyeni eziphambene, noma amaphutha ezinto ezibonakalayo.
2. Ukukhula Kwemifantu: Uma sekukhona imifantu emincane, iqala ukukhula ngaphansi kwemijikelezo yomthwalo esetshenzisiwe. Umjikelezo ngamunye womthwalo ubangela ukwanda kancane kancane kokukhula kwemifantu.
3. Ukwehluleka Kokugcina: Lapho umfantu ufinyelela usayizi obalulekile, izinto azisakwazi ukumelana nomthwalo osetshenzisiwe futhi ziyahluleka ngokuzumayo.
Izici Ezithinta Ukukhathala Kwezinto Ezibonakalayo
– Uhlobo Lwezinto: Insimbi, i-aluminium, kanye nepulasitiki ngayinye inezimpawu zayo zokukhathala.
– Umthwalo Osetshenzisiwe: Imithwalo ephindaphindwayo ene-amplitude ephezulu isheshisa ukwehluleka kokukhathala.
– Ukugxila Kokucindezeleka: Ukungalungi kobuso noma ukuba khona kwamaphutha amancane kusheshisa ukuqala kokuqhekeka.
2. Ukugqwala
Ukuqonda Ukugqwala
Ukugqwala kuwukuwohloka kwezinto ngenxa yokusabela kwamakhemikhali noma kwe-electrochemical endaweni yazo. Ukugqwala kuvame ukuba yinkinga enkulu ezintweni zensimbi lapho zivezwa emoyeni, umswakama, noma amakhemikhali agqwalisayo.
Indlela Yokugqwala
Ukugqwala kungaqaliswa ngezindlela eziningana, okuhlanganisa:
1. Ukugqwala Okufanayo: Ukuwohloka okusabalala ngokulinganayo ebusweni bezinto.
2. Ukugqwala Kwezimbobo: Ukwakheka kwezimbobo ezincane ezingangena ngaphakathi kwento.
3. Ukugqwala kwe-Galvanic: Kwenzeka lapho izinto ezimbili zensimbi ezahlukene zihlangana endaweni egqwalisayo.
4. Ukugqwala kwe-Interfacial/Intergranular: Ukuwohloka kwenzeka emingceleni yokusanhlamvu kwezinto.
Izici Ezithinta Ukugqwala
– Indawo: Ukungcoliswa komoya, ukuba khona kwamanzi, noma izixazululo ze-asidi/isisekelo kusheshisa ukugqwala.
– Izakhiwo Zezinto: Ukwakheka kwamakhemikhali kwezinto kanye nokwelashwa kwendawo kuthinta ukumelana nokugqwala.
3. Ukwehluleka Ngenxa Yokuguguleka Nokuklebhuka
Incazelo Yokuguguleka Nokuklebhula
Ukuguguleka ukulahleka kwezinto ezivela endaweni ethile okubangelwa ukuthintana ngomshini nenye indawo. Ukuguguleka kuyinkinga evamile ezingxenyeni zomshini kanye nemishini esindayo.
Indlela Yokugqoka
Ukuguga nokuklebhula kungahlukaniswa ngezinhlobo eziningana:
1. Ukuguguleka Okubi: Kwenzeka lapho izinhlayiya eziqinile zigudla ebusweni bento.
2. Ukuguguleka Okunamathelayo: Kwenzeka ngenxa yokudluliselwa kwezinto phakathi kwezindawo ezithintanayo.
3. Ukukhathala: Kwenzeka ngenxa yemijikelezo yomthwalo ebangela ukwakheka kwemifantu nokukhula.
Izici Ezithinta Ukuguga Nokuklebhuka
– Ukuqina Kwezinto: Izinto eziqinile zivame ukumelana nokuguguleka.
– Ikhwalithi Yokugcoba Yokwakheka Komphezulu: Ukusebenzisa i-lubricant efanele kunganciphisa ukuguguleka.
– Isivinini kanye Nomthwalo: Isivinini sokungqubuzana kanye nobukhulu bomthwalo wokuthintana kuthinta izinga lokuguguleka.
4. Ukucindezeleka Okuqhekekile
Ukuqonda Ukucindezeleka Okubangela Ukucindezeleka
Ukuqhekeka kokucindezeleka kuvame ukwenzeka lapho into ivezwa ekucindezelekeni okukhulu isikhathi esifushane noma ekucindezelekeni okulinganiselwe isikhathi eside.
Indlela Yokuqhekeka
Imifantu ingabangelwa yizinto eziningana:
1. Ukuqhekeka Kokucindezeleka Nezinga Lokushisa: Kwenzeka kakhulu ezintweni ezisebenza ezindaweni ezinokushisa okuphezulu.
2. Ukucindezeleka Ukuqhekeka Kokucindezeleka: Inhlanganisela yokucindezeleka okuqinile nendawo egqwalisayo.
Izici Ezithinta Ukuqhekeka
– Indawo Yokusebenza: Amazinga okushisa aphezulu okusebenza kanye nezindawo ezigqwalisayo.
– Izici Zezinto: Ukuqina, amandla okunamathela, kanye nokumelana namazinga okushisa aphezulu kanye nokugqwala.
5. Ithonya Lemvelo
Izimo Zemvelo Ezithinta Ukwehluleka Kwezinto Ezibalulekile
Indawo yokusebenza inomthelela omkhulu ekwahlulekeni kwezinto zokwakha. Izici ezahlukahlukene zemvelo ezithonya lokhu zifaka:
1. Izinga Lokushisa: Izinga lokushisa eliphakeme kakhulu lingabangela ukuthi izinto ziguquke noma zihluleke ukushisa.
2. Umswakama: Ukuba khona kwamanzi kungasheshisa ukugqwala nokuqhekeka.
3. Izinto Ezingcolisayo Zamakhemikhali: Isenzo samakhemikhali anjenge-asidi noma izisekelo singalimaza isakhiwo sangaphakathi sezinto.
Izibonelo Zokwehluleka Kwezinto Ezibonakalayo Ngenxa Yethonya Lemvelo
I-Titanic: Ukwehluleka kwezinto eziku-Titanic kwakubangelwa kakhulu indawo yolwandle eyayingcola futhi ibanda, okwabuthakatha insimbi.
Indiza yeConcorde: Ingozi yendiza ebangelwe ukwehluleka kwezinto ezibonakalayo ngenxa yokuhlanganiswa kokucindezeleka, izinga lokushisa, kanye nokugqwala.
Ukuvimbela Nokunciphisa Ingozi
Amasu Okunciphisa Ukwehluleka Kwezinto Ezibalulekile
Kungathathwa izinyathelo eziningana ukunciphisa ingozi yokwehluleka kwezinto ezibonakalayo, okuhlanganisa:
1. Ukukhetha Izinto: Ukukhetha izinto ezinezakhiwo ezifanelana nezimo zokusebenza.
2. Ukwelashwa Kwezinto: Ukwandisa amandla nokumelana kwezinto ezisetshenziswayo endaweni ezungezile ngezinqubo ezikhethekile zokwelapha njengokwakha, ukuqinisa, noma ukuzondisa.
3. Ukuhlolwa Nokunakekelwa: Hlola futhi unakekele imishini njalo ukuze uthole izimpawu zokuqala zomonakalo.
4. Ukuvikelwa Kwemvelo: Ukusebenzisa izivikelo noma izembozo ukuvikela izinto ezimweni ezibucayi.
Isiphetho
Ukwehluleka kwezinto ezibonakalayo kuyinto ebalulekile ethonywa izici ezahlukahlukene zemishini nezemvelo. Ukuqonda izindlela zokwehluleka njengokukhathala, ukugqwala, ukuguguleka, ukuqhekeka kokucindezeleka, kanye nethonya lemvelo kubalulekile ekuthuthukiseni izinto zokwakha nemiklamo eqinile. Ngokukhetha izinto ezibonakalayo ngendlela efanele, ukulungiswa kokuvimbela, kanye nokusungula izinto ezintsha kwezobuchwepheshe, ingozi yokwehluleka kwezinto ezibonakalayo ingancishiswa, kuqinisekiswe ukuphepha nokusebenza kahle kwezicelo ezahlukene zezimboni.
