Kwimigca yemveliso ezenzekelayo ekhawulezayo yeenapukeni kunye neenapkin zokucoca, umzuzwana ngamnye wokungasebenzi kuthetha ukulahlekelwa yimali efunyenwe nzima. Ukuqinisekisa ukuba imveliso ayizali, inkqubo yokubulala iintsholongwane ze-corona iqhubeka unyaka wonke kwiindawo zemveliso; nangona oku kubulala iintsholongwane, kukwakhupha inani elikhulu le-ozone. Kwiinkqubo zokuqhuba, i-ozone "yityhefu esebenza kancinci" efihliweyo.

Iifektri ezininzi ziye zahlangabezana neengxaki ezifanayo: iibhanti eziqhelekileyo ezihambelanayo, xa zisebenza kwindawo etyebileyo kwi-ozone, kungekudala zivelisa umgubo womphezulu, ukuqhekeka okunzulu, okanye ukuqhekeka ngaphandle kwesilumkiso. Ukutshintshwa rhoqo akupheleli nje ekunyuseni iindleko zokusebenza nokugcinwa kodwa kukwaphazamisa neshedyuli yemveliso encinci. Kwinkampani enkulu yaseMelika yemveliso yococeko eyasekwa ngo-1872, naluphi na umngcipheko onokuthi uchaphazele amandla emveliso kunye nemigangatho yococeko kufuneka ususwe. Ngoko ke baphendukela kuthi—umvelisi weebhanti ezihambelanayo ezimelana ne-ozone ezigxile kwizisombululo ezikhethekileyo zokudlulisa—benethemba lokuphelisa eli phupha libi “lokungaphumeleli kwebhanti ngaphambi kwexesha.”

I. Intlungu Efihlakeleyo Engasemva Kwenkampani Eneminyaka Elikhulu

Zingena kumgangatho wemveliso wale nkampani inkulu yemveliso yococeko yaseMelika eneminyaka elikhulu ubudala, amashumi amawaka eemveliso zococeko aphuma kumgca wokudibanisa umzuzu ngamnye. Nangona kunjalo, ukuvezwa ixesha elide kwi-ozone enoxinzelelo oluphezulu kuye kwabangela umonakalo omkhulu kwiibhanti eziqhelekileyo ezihambelanayo kwimigca yemveliso. Ekuqaleni ziguquguquka, ezi bhanti ezihambelanayo zalahlekelwa bukuqina kwazo kwiinyanga ezimbalwa nje phantsi kohlaselo oluqhubekayo lwe-ozone, imiphezulu yazo igqunywe ziintanda ezincinci kwaye zikwasemngciphekweni wokuqhekeka kwamasuntswana.

 

Kwinkampani eneminyaka elikhulu ubudala ephatha umgangatho njengomthombo wobomi, oku bekunganyamezeleki. Into ababeyifuna ngokukhawuleza yayingekuko nje ibhanti ehambelanayo engamelani ne-ozone, kodwa yinkqubo yokuqhuba epheleleyo ekwaziyo ukusebenza ngokuzinzileyo ixesha elide kwiimeko "ezinzima" ezinjalo. Oku akusiyonto yokutshintsha iindawo kuphela; yimfazwe yokukhusela ukusebenza kakuhle kwemveliso kunye nodumo lophawu.

II. Ukwandisa Ixesha Lobomi Bebhanti Kwinqanaba LeeMolekyuli

 

Njengomvelisi ochwephesha weebhanti zexesha ezimelana ne-ozone, siyaqonda ukuba ukujongana nonobangela kubaluleke ngaphezu kokunyanga iimpawu nje kuphela. Emva kokufumana isicelo, iqela lethu le-R&D laya kwangoko kwindawo yokwenza uphando olucokisekileyo malunga noxinzelelo lwe-ozone, uxinzelelo lokusebenza, kunye namanqanaba okucoceka.

 

Ingcambu yengxaki yayikubuthathaka besakhiwo seekhemikhali zezinto eziqhelekileyo—ubuthathaka obunokusetyenziswa yi-ozone ngokulula. Ukujongana noku, siphuhlise indlela yokwenza eyenzelwe ngokukodwa le nkampani inkulu: ngokuguqula ngokupheleleyo inkqubo yezinto ezisisiseko kunye nokufaka izinto zokukhusela ezingasebenziyo ezenziwe ngokukodwa, sakhe ukhuselo oluqinileyo lweekhemikhali kwinqanaba le-microscopic. Le bhanti ye-synchronous engamelani ne-ozone eyenziwe ngokwezifiso inikezele ngokusebenza okugqwesileyo kwiimvavanyo zokwaluphala ezikhawulezileyo—nangona emva kokuvezwa ixesha elide kwi-ozone, igcine ukuguquguquka okugqwesileyo kunye namandla, ayizange ivelise nkunkuma ngexesha lokusebenza, kwaye yahlangabezana ngokupheleleyo neemfuno zemveliso yokucoceka okuphezulu.

 

Xa iibhanti ezintsha zexesha zazisebenza kakuhle kumgca wemveliso kangangeenyanga kwaye zihlala zintsha, ibunzi lomthengi elinomqolo ekugqibeleni lakhululeka. Oku akupheleli nje ekwandiseni ubomi benkonzo kodwa kwabonelela ngokhuseleko oluqinileyo lokuqhubeka kwemveliso.

 

III. Ukuphendula Kuyo Yonke Imbopheleleko Enezakhono Eziqinileyo

 

Ukufumana ukuthenjwa kwesi sikhulu seemveliso zococeko saseMelika esineminyaka elikhulu ubudala, esasekwa ngo-1872, kwakungeyonto iphumelele ngobusuku obunye. Singumvelisi weebhanti ezihambelanayo ezingamelani ne-ozone ezidibanisa uphando nophuhliso, imveliso, kunye nokuthengisa, kunye neqela leenjineli ezingama-35 ezigxile kakhulu kushishino kunye nelebhu yezinto ezixhotyiswe ngokupheleleyo. Nokuba kubandakanya iimeko zokusebenza ezikhethekileyo ezifana nokuxhathisa i-ozone, ukuxhathisa ubushushu obuphezulu, okanye ukuxhathisa i-asidi kunye ne-alkali, sinokuphendula ngokukhawuleza ukubonelela ngeenkonzo zobungcali zokwenza ngokwezifiso iibhanti ezihambelanayo ezingamelani ne-ozone.

 

Siyiqonda itekhnoloji, kwaye siyaziqonda ngcono iimfuno zabathengi bethu. Ukususela kuphando lokuqala lweemeko zokusebenza kunye nokukhethwa kwezinto ukuya kuvavanyo lweesampuli, ukuveliswa ngobuninzi, kunye nokulandelela emva kokuthengisa, sinikezela ngenkxaso yobugcisa yomntu ngamnye kuyo yonke le nkqubo. Siyaqonda ukuba abathengi bethu abakhethi nje kuphela ibhanti ehambelanayo engamelani ne-ozone—basinika uxolo lwengqondo oluza nemveliso ezinzileyo. Yiyo kanye le mvakalelo yoxanduva eye yasenza saziwa njengenani elikhulayo labathengi kwihlabathi liphela.

 

Ukuba umgca wakho wemveliso nawo unengxaki yokubola kwe-ozone, kwaye ukutshintshwa rhoqo kweebhanti zexesha eliqhelekileyo kukushiya uxinezelekile, kutheni ungaqhagamshelani nathi? Sisebenzisa ubuchule bethu obuqinisekisiweyo bokwenza ngokwezifiso iibhanti zexesha ezimelana ne-ozone, siza kuyila isisombululo sokuqhuba esilungiselelwe ngokugqibeleleyo iimeko zakho zokusebenza—ukuqinisekisa ukusebenza kwezixhobo okugudileyo kunye nenkqubo yemveliso engenamthungo.
