Kukho izizathu ezahlukeneyo zokungaphumeleli kunye nomonakalo we isixhobo sokubona igesiUkuqinisekisa ukuba isixhobo sinokwenza imisebenzi yaso efanelekileyo ngexesha elichaziweyo, kufuneka kuqatshelwe la manqaku alandelayo ngexesha lokusetyenziswa kwaso.

Igesi yenye yezona mithombo zamandla zisetyenziswa kakhulu kubomi bethu bemihla ngemihla. Ukupheka, ukuhlamba, ukufudumeza... zonke ezi zinto zixhomekeke ekusetyenzisweni kwegesi. Ukhuseleko lwegesi yeyona nto iphambili. Namhlanje, sidwelise "iingcamango ezingalunganga" zokusetyenziswa kwegesi eziqhelekileyo. Ungazithelekisa kwaye uzihlole ngokwakho ukuze ubone ukuba uziphephe na ~

Ngomhla wama-23 emini, umsitho wokuvala iNgqungquthela yeHlabathi yeGesi ka-2025 wabanjwa kwiZiko leeNgqungquthela zeSizwe laseBeijing, nto leyo eyaphawula ukuqukunjelwa ngempumelelo kweNgqungquthela yeHlabathi yeGesi yama-29. Ngexesha lengqungquthela, iqela laseTshayina lomququzeleli kunye nobunkokeli be-International Gas Union (IGU) bathathe inxaxheba kunye kwaye basebenzisane ngokusondeleyo, benikezela umsitho otyebileyo noneziqhamo kwishishini legesi lehlabathi. Umsitho wokuvala waqala kwindawo ephilayo, kwaye umdlalo omhle wenkcubeko wazisa imibuliso yenkcubeko kwingqungquthela. Abadanisi badlale umdaniso obizwa ngokuba yi-"Wing Chun" owawuquka iindlela zeSouthern Fist, walandelwa yingoma emnandi ethi "Time to say goodbye" evakala kuyo yonke indawo, ebonisa ukuhlanganiswa okuhle kunye nokubonakaliswa okutsha kweenkcubeko zaseTshayina nase-Itali, bephumelela ihlombe kubaphulaphuli. Ividiyo yesishwankathelo sengqungquthela ihlolisise amaxesha amnandi engqungquthela yeentsuku ezine, ivuselela iinkumbulo ezimnandi zexesha lengqungquthela kubathunywa ababekho.

Kwiinkqubo zoshishino zanamhlanje, i-nitric oxide (NO) idlala indima embaxa-mbini - iqhuba inkqubela phambili kwishishini leekhemikhali, lezonyango, kunye namanye amashishini ngelixa ibeka umngcipheko omkhulu wokhuseleko. Eli nqaku libonelela ngohlalutyo olunzulu lweempawu ze-NO, iingozi, kunye namaqhinga okuphendula.

Njengoko ixesha lezikhukula lisondela, kudla ngokubakho imvula enkulu kunye nemozulu enamandla yomoya, kwaye iimeko ezifana nokugcwala kwamanzi kunye nezikhukula nazo ziyenzeka ngamanye amaxesha. Xa kukho imvula enkulu, singazithintela njani izixhobo zokubona igesi ukuba zingagcwali? Ngaba isixhobo sisasebenza kakuhle emva kokuba sigcwaliswe ngamanzi?

Zininzi izizathu zokuba izixhobo zokubona igesi zihlale zilumkisa, ikakhulu kuquka ukubonwa koxinzelelo lwegesi olungaqhelekanga, utshintsho kwindawo engqongileyo, kunye neengxaki ngesixhobo ngokwaso. Ezi zilandelayo zezinye zezinto eziqhelekileyo ezibangela ii-alamu zokubona igesi ezingaqhelekanga.

Kwindawo enzima yemveliso yemizi-mveliso kunye neendawo zasezidolophini, i-nitrogen dioxide NO2 yigesi efuna ingqalelo yethu esondeleyo. Ayisiyonto ixhaphakileyo nje kuphela ngenxa yeenkqubo ezahlukeneyo zemizi-mveliso kodwa ikwanegalelo elikhulu ekungcoliseni umoya, nto leyo ebeka izisongelo kwimpilo yabantu nakwindalo esingqongileyo. Eli nqaku liza kuhlola ngokubanzi uhlobo, iingozi, kunye namanyathelo okuthintela anxulumene ne-nitrogen dioxide.

Ukuqinisekisa imveliso ekhuselekileyo, izixhobo zokubona igesi zisetyenziswa kakhulu kumashishini ahlukeneyo. Izixhobo zokubona igesi zinokujonga ukuvuza kweegesi ezinobuthi neziyingozi kunye neegesi ezinokutsha emoyeni ngexesha langempela, zithintele ngempumelelo ukwenzeka kweengozi ezahlukeneyo ezifana nemililo, ukuqhuma kunye neetyhefu. Xa usebenzisa izixhobo zokubona igesi kubomi bemihla ngemihla, abasebenzisi baya kufumanisa ukuba uluhlu lokufumanisa kwileyibhile yesixhobo ludla ngokubonisa amanani afanayo afana ne-0 - 100LEL% okanye i-0 - 2000PPM. Okanye kwisikrini se-LCD sesixhobo sokubona igesi, i-VOL% okanye i-PPM nazo zinokuvela. Zithetha ukuthini ezi yunithi zintathu ngokukodwa kwaye zitshintshana njani?

Namhlanje, siza kuqhubeka nokwazisa enye igesi-ammonia eqhelekileyo.

01. Yintoni ukhuseleko lwe-IP?
