Umphumela we-formaldehyde awuyona imfanelo yebhodi. Uwumphumela wokulandelana okulawulwayo — isampula, uphawu, umthwalo, isimo, umoya wesampula, ukuhlaziya — futhi isinyathelo ngasinye singahambisa inombolo yokugcina.
Lesi sihloko silandela iphaneli eyodwa nge-Igumbi lesimo sezulu elingu-1 m³gijima, ngokulandelana kwelebhu okukwenza, bese ubhala lapho ukulandelana kuvame ukuphulwa khona.
Izinto ezibalulekile okufanele uzicabangele
- Ikamelo lilinganisa ukukhishwa ngaphansi kwezimo ezichaziwe, bese likwenza kube ngokwendawo evamile — ibhodi alikaze lihlolwe “njengoba linjalo”.
- Isici sokulayisha kanye nezinga lokushintshana komoya ndawonye kunquma ukuhlushwa; ushintsho noma yikuphi futhi umphumela awufani.
- Ukuvalwa komphetho kuyindlela eyodwa evame kakhulu yokuthola imiphumela ekhuphukile.
- Umphumela usebenza kuphela esimweni esizinzile, hhayi endaweni yokuqala yokuthatha isampula.
KunganiIgumbi elingu-1 m³, akulona igumbi langempela
Igumbi langempela aliphindeki: umthamo uyahlukahluka, umoya uyahlukahluka, futhi awekho amakamelo amabili aphethe inani elifanayo lefenisha. Igumbi lishintshana ngokulawula okungokoqobo, futhi ukulahlekelwa kukhokhelwa yisilinganiso esichaziwe.
Leso silinganiso siyisici sokulayisha — amamitha-skwele ebhodi eliveziwe nge-cubic meter ngayinye yomoya wegumbi. Ngendlela engu-1 m³ ngaphansi kwe-GB 18580, ngokuvamile kuba yi-1 m²/m³, okuvumela ukuthi umphumela webhentshi udluliselwe ekamelweni lanoma yiluphi usayizi.
I-physics ilula ngokwanele ukuthi ingabhalwa phansi. Ekulinganisweni, ukuhlushwa kulingana nesilinganiso sokukhishwa kwendawo ethile esiphindaphindwe yi-loading factor futhi sihlukaniswe ngesilinganiso sokushintshana komoya. Yonke ipharamitha ecacisweni legumbi ikhona ukuze ibambe elinye lalawo magama lingaguquki.
Isinyathelo 1 — Faka isampula esimweni sayo ngaphambi kokuba ingeniswe
Amaphaneli alinganiswa ngokushisa okulawulwayo kanye nomswakama ngaphambi kokuhlolwa, ngakho-ke umswakama womphezulu usesimweni esaziwayo. Ibhodi elithathwe ngqo esitokisini liphethe i-gradient yomswakama eshintsha ukukhishwa kwangaphambi kwesikhathi.
Kumaphaneli aklanywe ngobunjiniyela kanye namaphaneli ahlanganisiwe lesi sigaba sokulungisa yilapho isampula isikwa khona endaweni ethile — kanti imiphetho esikiwe iyinkinga isinyathelo esilandelayo okufanele siyixazulule.
Isinyathelo 2 — Vala imiphetho
Ukuvala umphetho kuvimbela ukuphuma komoya ebusweni bokuhlobisa, ukuze umphumela uchaze umkhiqizo njengofakiwe kunokuba umkhiqizo njengosikiwe. Itheyiphu ye-aluminium foil iyindlela evamile, futhi kumele iphelele.
Unqenqema olungavaliwe noma oluvalwe kancane luveza izinto ezingaphakathi ezintsha, ezikhipha okungaphezu kobuso obubheke phezulu. Umphumela uba inombolo ebonakala sengathi ingenzeka ehluleka ukuhlolwa kabusha - futhi ukuhlolwa kabusha kuvame ukusolwa ekamelweni.
Isinyathelo 3 — Layisha bese uvala
Amasampula avalwe abekwa esitendini ngaphakathi kwegumbi, ahlukaniswe ukuze umoya ujikeleze kuzo zombili izinhlangothi. Ukulayisha kubalwa kusukela endaweni eveziwe, hhayi kusukela ebuningini, yingakho ubukhulu beshidi bungangeni ekubalweni kodwa inani lebhodi liyangena.
Uma selivaliwe, igumbi ligcina amaphuzu alo amisiwe: izinga lokushisa kanye nomswakama ohlobene ngamanani aqanjwe ku-standard, kanye nesilinganiso sokushintshana komoya esibekiwe esigcinwa ukunikezwa kanye nokukhishwa komoya okulawulwa ukugeleza kobuningi.
Isinyathelo 4 — Fakazela ukuthi igumbi lihlanzekile
Ngaphambi kokuhlolwa okugcwele, ukuhlolwa okungenalutho kusungula ukuhlushwa kwangemuva. Amakamelo amunca bese kamuva akhipha i-formaldehyde; igumbi elibukeka lihlanzekile elasetshenziswa okokugcina kwisampula yokukhishwa okuphezulu lingathwala ukungcola kumphumela olandelayo.
Yilapho futhi kuqinisekiswa khona ukubuyisa — ikhono lesitimela sokuhlola ukubamba nokulinganisa inani elaziwayo. Ngaphandle kwalo, ukufundwa okuphansi kungasho ibhodi lokukhipha ukungcola okuphansi noma umugqa wokuhlola ovuzayo, futhi lokhu kokubili akuhlukaniseki.
Isinyathelo 5 — Isampula kuze kube yilapho isimo sizinzile
Ukukhishwa komoya kuyabola njengoba ungqimba olungaphezulu luncipha, ngakho-ke ukuhlushwa kuyakhuphuka, kuphakame bese kuhlala phansi. Ukuthatha amasampula kuvame ukuqala ngemva kwesikhathi sokuqala esichazwe kule ndlela futhi kuyaqhubeka nsuku zonke kuze kube yilapho kuboniswa isimo esizinzile — ngokwesiko, imiphumela emibili elandelanayo evumelana ngaphakathi kwesilinganiso esincane.
Ngakho-ke, ukulinganisa okukodwa kwasekuqaleni akuwona umphumela. Kuyindawo yedatha esendleleni eya kwenye, futhi ukuyibika njengempendulo kungenye yamaphutha avame kakhulu kumadokhumenti abahlinzeki.
Isinyathelo 6 — Hlaziya futhi wahlulele
Amasampula omoya adonswa nge-scrubber noma i-DNPH cartridge futhi alinganiswa ngendlela ye-acetylacetone noma nge-HPLC. Womabili ayamukelwa; womabili adinga ukulinganiswa kanye nesikhala esingenalutho ngesikhathi esifanayo namasampula.
Inani lokugcina liqhathaniswa nomkhawulo kuzinga elifanele — ku-GB 18580 umkhawulo we-E1 ungu-0.124 mg/m³ — futhi umbiko kufanele usho isici sokulayisha, izinga lokushintshana komoya, izinga lokushisa, umswakama, izinsuku zokuthatha amasampula kanye nendlela yokuhlaziya eceleni kwawo.
Amaphuzu asethiwe, ishejuli yokusampula kanye namanani omkhawulo achazwe kuhlelo lwamanje lwendinganiso ngayinye futhi abuyekezwa ngezikhathi ezithile. Qinisekisa ngokumelene nohlelo olucashunwe kufayela lakho lobuchwepheshe ngaphambi kokushicilela isimangalo.
Lapho iketanga livame ukuphuka khona
- Ukuvalwa komngcele okungaphelele— imbangela evame kakhulu yomphumela engenakuphindwa.
- Izinga lokushintshana komoya ophephukayo— isihlungi esilayishayo izinyanga eziningi sishintsha i-denominator buthule, futhi iphutha libukeka njengoshintsho kumkhiqizo.
- Ukungazinzi kwezinga lokushisa— ukukhishwa kwegesi kuncike kakhulu ekushiseni, futhi ingxenye encane yezinga eligcinwe izinsuku eziningi ibaluleke kakhulu kunohambo olukhulu lwesikhashana.
- Ukubika ngaphandle kwemibandela— inombolo engenalo isici sokulayisha, akukho silinganiso sokushintsha komoya kanye nokungabi nosuku lokuhlola akuyona imiphumela yokuhlolwa.
Okufanele ukusho ekamelweni
Izici ezine zihlukanisa igumbi elingasekela isimemezelo kwelinye elingakhiqiza izinombolo kuphela:
- Amaphuzu abekwe eceleni— izinga lokushisa, umswakama kanye nezinga lokushintshana komoya elilawulwayo nelibhalwe phansi, hhayi nje kuphela eliboniswayo.
- Ukulawulwa kokushintshana komoya okulandelekayo— ukulinganiswa kokugeleza kwesisindo ekuhlinzekweni nasekukhishweni komoya, ngerekhodi ngokusebenza ngakunye.
- Ingaphakathi elihlanzekayo eline-adsorption encane— izindawo ezingenasici kanye nenqubo engenalutho ebhalwe phansi.
- Amachweba okuthatha amasampula abekwe ngendlela yokuthi ameleke, kufakwe isitimela sokuthatha amasampula kunokuba kucatshangelwe.
I-Lituo ibilokhu ikhiqiza amathuluzi okuhlola ezemvelo kanye nemishini kusukela ngo-2008.igumbi lokuhlola ukukhishwa kwe-formaldehydeububanzi buhlanganisa indlela engu-1 m³ yamaphaneli asekelwe okhunini, phansi okuhlanganisiwe nezinye izinto zangaphakathi, ngokushisa okulawulwayo, umswakama kanye nokushintshana komoya, futhi isetshenziswa kanye nobubanzi bemishini yokuhlola indawo ukuze kutholakale ukufaneleka kwezinto.Buka uhla lokuhlola imvelo →
Imibuzo ejwayelekile ukubuzwa
Kuthatha isikhathi esingakanani ukuhlolwa kwegumbi elingu-1 m³?
Izinsuku, hhayi amahora. Ukulungisa isimo, ukulayisha, ukuzinza kanye nokuthatha amasampula nsuku zonke ukuze kube sesimweni esizinzile ngokuvamile kuthatha isonto elilodwa kuya kwamabili, futhi ishejuli kufanele ihlelwe ngokuhambisana nalokho kunokuba icindezelwe.
Ingabe igumbi elifanayo lingahlola izinhlobo ezahlukene zamabhodi?
Yebo, uma nje kungekho lutho olusele kanye nenqubo yokuhlanza ebhaliwe iqediwe phakathi kwemikhiqizo. Ukungcola okuhlanganisiwe phakathi kwesampula yokukhishwa okuphezulu kanye nesampula yokukhishwa okuncane kuyingozi enkulu.
Kungani 23 °C kanye nomswakama ohlobene ongu-45%?
Ngoba zilinganisa izimo ezijwayelekile zangaphakathi ngenkathi ziqinile ngokwanele ukulawula. Ukukhishwa komoya kukhuphuka kakhulu ngokushisa, futhi umswakama uthinta i-hydrolysis ye-resin, ngakho-ke zombili ziqiniswa yindlela esikhundleni sokukhethwa yilebhu.
Ingabe umphumela wendlela ye-desiccator uyalingana?
Cha. Indlela ye-desiccator iyisivivinyo esihlukile esinokuhlobana okuhlukile, futhi imiphumela ayishintshisani namanani e-chamber. Memezela indlela, hhayi inombolo kuphela.
