    Iipayipi eziDityanisiweyo ezijikelezayo zeepayipi zegesi ezingaphantsi komhlaba EN10219 Umfanekiso obonisiweyo
    • Iipayipi eziDityanisiweyo ezijikelezayo zeepayipi zegesi ezingaphantsi komhlaba EN10219

    Inkcazo emfutshane:

    Sizisa iipayipi zethu ezidityanisiweyo ezikumgangatho ophezulu, ezenzelwe ukuhlangabezana neemfuno ezifunekayo zokufakelwa kwemibhobho yegesi engaphantsi komhlaba. Ezi payipi zenziwe ngononophelo ngokwemigangatho engqongqo ebekwe kwi-EN10219, ukuqinisekisa iimfuno eziphezulu zobuchwephesha zokuhanjiswa kweendawo ezingenanto ezidityanisiweyo ezakhiwe ngokubandayo kwiintsimbi ezingezizo ezomileyo nezincinci.


    Iinkcukacha zeMveliso

    Iithegi zeMveliso

    Zethuimibhobho edibeneyo ejikelezayozezona zisombululo zifanelekileyo kwiiprojekthi apho ukumelana nokugqwala kunye nokuqina kwesakhiwo kubaluleke kakhulu. Inkqubo yokuwelda ejikelezayo eyahlukileyo ayigcini nje ngokwandisa amandla ombhobho, kodwa ikwabonelela ngomphezulu ongenamthungo, inciphisa umngcipheko wokuvuza kunye nokusilela. Oku kubenza bafaneleke ngakumbi kwiindawo ezinzima ezidla ngokufunyanwa kwiindawo ezingaphantsi komhlaba.

    Umgangatho we-EN10219 uqinisekisa ukuba imibhobho yethu yenziwe ngokuchanekileyo nangomgangatho, iqinisekisa ukuba inokumelana noxinzelelo kunye nemingeni yokuthuthwa kwegesi yendalo. Igxile ekuqineni nasekuthembekeni, imibhobho yethu edibeneyo ejikelezayo yenzelwe ukubonelela ngokusebenza okuhlala ixesha elide, ukunciphisa isidingo sokugcinwa rhoqo kunye nokutshintshwa.

    a. Indlela yokususa ioksijini ichazwe ngolu hlobo lulandelayo:FF: Intsimbi ebulewe ngokupheleleyo equlethe izinto zokubopha initrogen ngobuninzi obaneleyo ukubopha initrogen ekhoyo (umz. ubuncinci be-0,020% iyonke ye-Al okanye i-0,015% ye-Al enyibilikayo).

    b. Ixabiso eliphezulu le-nitrogen alisebenzi ukuba ukwakheka kweekhemikhali kubonisa umxholo opheleleyo we-Al ongama-0,020% kunye nomlinganiselo ophantsi we-Al/N oyi-2:1, okanye ukuba kukho ezinye izinto ezaneleyo zokubopha i-N. Izinto zokubopha i-N mazirekhodwe kuXwebhu loHlolo.

    Ukongeza kulwakhiwo lwazo oluqinileyo, ezi mbhobho zilula kwaye kulula ukuziphatha, nto leyo eyenza ukufakwa kwazo kube lula kwaye kungabizi kakhulu. Nokuba uqalisa iprojekthi entsha yembhobho okanye uphucula inkqubo ekhoyo, iimbhobho zethu ezihlanganisiweyo ezijikelezayo zibonelela ngokudibanisa okugqibeleleyo kwamandla, ukuguquguquka, kunye nokuthobela imigangatho yoshishino.

    Khetha iipayipi zethu ezijijekileyo ezilungele iimfuno zakho zepayipi yegesi engaphantsi komhlaba kwaye ufumane uxolo lwengqondo oluza nokusebenzisa iimveliso ezihlangabezana neemfuno zakho.EN10219imigangatho. Themba ukuzibophelela kwethu kumgangatho nokusebenza ukuqinisekisa ukhuseleko nokusebenza kakuhle kweziseko zakho zegesi.
