Ukukhiqizwa kwemboni yokupakisha kungasebenzisa isikali sokupakisha esinobuningi

Ukukhiqizwa kwezimboni kwanamuhla kanye nokuphila kwansuku zonke akuhlukaniseki ekulinganisweni, futhi ngokuthuthukiswa kokukhiqiza, ukunemba kwesisindo kuyathuthuka, ikakhulukazi ekupakisheni, ekudleni, kumakhemikhali, kwezemithi nakwezinye izimboni, kuyadingeka ukuthi kube nokunemba okuphezulu kwesisindo. Ngokwesakhiwo somshini ukuze kufezwe idivayisi enesisindo esinembile kakhulu, hhayi nje isakhiwo esiyinkimbinkimbi, kanye nokusekelwa (i-blade nommese) Ibuthakathaka futhi kulula ukuyigqoka nokugqwala, iqinile endaweni yokusebenza, umthwalo womsebenzi wokulungisa mkhulu, ubuthakathaka obukhulu isivinini sesisindo sihamba kancane, ukusebenza kahle okuphansi, futhi asikwazi ukuzivumelanisa nezidingo zokuthuthukiswa kokukhiqiza. Ekhulwini leminyaka lama-60 eledlule, abantu bathuthukise uhlobo lwesilinganiso se-elekthronikhi esihlanganisiwe se-elekthronikhi, sakhiwe uhlelo lwe-lever, idivayisi ye-grating kanye nesekethe yezingxenye ezintathu. Uhlelo lwe-lever ngaphansi kwesenzo somthwalo, ukufuduka, idivayisi ye-grating iguqula ukufuduka kube yisekethe ye-elekthronikhi, isignali yedijithali ngemuva kokuhlanganiswa ngokusho komkhiqizi onethuluzi ledijithali libonisa inani lesisindo. Ukuhlanganiswa ngokusho komkhiqizi lesi sikali kunesikali se-lever esithuthukisiwe ngokunemba, ukusetshenziswa kulula kakhulu, amanani esisindo atholakalayo ukubonisa okubonakalayo kwedijithali, kanye nesignali yesisindo ingadluliselwa ibanga elide. Isivele ikhula ngokushesha okukhulu, isikali sokupakisha esinobuningi asiyona nje into eyodwa, kodwa kancane kancane sivumelana nezinguquko zemakethe, singene emgqeni wokukhiqiza kuzo zonke izindlela zokuphila. Ingakwazi ukufeza isilinganiso sobuningi, isikhwama esizenzakalelayo, ukuvalwa okuzenzakalelayo, umhlaba, ipulasitiki, ukuphrinta, ukuphalethiza okuzenzakalelayo kanye nokuhlanganiswa okuguquguqukayo kwenqubo yokuhlanganisa. Ukusetshenziswa okuguquguqukayo kwesikali sokupakisha esinobuningi, futhi kwenza inqubo yonke yokukhiqiza ibe lula kakhulu, ukusebenza kube lula kakhulu futhi. Inhlanganisela ithe ifektri ikhuluma ngokupakisha okuningi kokukhiqiza embonini ingasetshenziswa esikalini sokupakisha esinobuningi. Njengokudla, ukudla okuphakelayo, ukudla, imbewu, kanye nezimboni zamakhemikhali, uma kusetshenziswa kuphela ukupakisha okwenziwayo, hhayi nje kuphela ukuthi ukusebenza kahle kuhamba kancane, futhi umphumela awulungile, kungaholela ekuhlinzekeni ngesidingo semakethe, ngakho-ke lokhu futhi kuqondile esikalini sokupakisha esinobuningi kunganikeza ukukhushulwa okusheshayo emakethe isikhala esiningi sokukhula. Ukucebisa impilo yezinto ezibonakalayo kanye nokudla okulula akusekho okukhethekile ezinganeni, abasebenzi abaningi basehhovisi bahlala bethanda ukudla okulula eceleni. Ngokwezibalo, ngo-2011, ukuthengiswa kokudla kwezwe lethu okuzilibazisa kunama-yuan angaphezu kwezigidigidi ezingama-200, futhi kukhula ngo-15% ngonyaka. Iziphathimandla zibikezela ukuthi ngo-2018, ukudla kwezwe lethu okuzilibazisa okunokuthengiswa kwaminyaka yonke okungafika kuma-yuan ayizigidi eziyizinkulungwane ezingu-480. Kusobala ukuthi intuthuko yamandla emakethe yokudla okulula kwaseShayina inkulu kakhulu.
