Isesengura ry'Impamvu Zitera Kwangirika kw'Imyenda

Dukurikije imibare ituruka mu Ishyirahamwe ry’Abashinwa rishinzwe kumesa imyenda, igipimo cy’igihombo cy’imyenda y’ubudodo mu Bushinwa buri mwaka kiri hagati ya 8% na 15%, kandi igihombo cy’ubukungu kitaziguye kigira hejuru ya 22% by’ikiguzi cy’imikorere. Iyi nkuru isesengura byimbitse impamvu nyamukuru zitera igihombo cy’imyenda y’ubudodo kandi igatanga ibisubizo.

Kwangirika kw'ibinyabutabire (38%)

● Ibidukikije bifite alkali

Iyo agaciro ka pH karenze 10, imbaraga z'imigozi y'ipamba zigabanukaho 17% ku nshuro. (Amakuru y'ibizamini bya Gulf Coast)

● Gushonga kw'ibisigazwa bya klorini

Igipimo cya chlorine cyigenga kirenze 50 ppm gituma imbaraga za fibre zigabanukaho 23%. (Ihame rya ISO 10528)

Kwangirika kw'imbaraga za mekanike (45%)

Kwangirika kw'imbaraga za mekanike bikunze kubaho mu gihe cyo kumesa, kumisha no gutwara. Urugero, iyo hari utubyimba duto, ibintu biturutse hanze, cyangwa uduce tw'imbere mu cyuma cyo kumesa, umuyoboro w'umwuka uhuha wo mu cyumaisambaza ry'ibiryo, ubuso bw'ipamba bw'ibikoresho byo kugaburiramo,abakora ipasi, naamadosiye, utuzu tw'imyenda n'imodoka zitwara abantu, n'ibindi, imyenda izashwanyagurika cyangwa ikarandurwe.

● Igitutu

Niba gahunda zo gukanda za mashini ikura amazi zidakwiye cyangwa amazi yo kumesa ari menshi cyane ku buryo umwenda w'ipamba urenza uruzitiro mu gihe cyo gukanda, ibi byose bizatera kuvunika no gucika kw'umwenda w'ipamba.

● Kwangirika kwa sisitemu yo kohereza ubutumwa

Ubuso buhura n'ibitambaro, nk'ingoma y'imbere y'imashini imesa mu nganda cyangwaicyuma cyo koza mu tunnel, cyangwa agapfunyika k'icyuma k'umukandara utwara imizigo, niba bifite udupfunyika, bishobora gutuma uruhu rw'umukandara rucika hagati ya cm 1.2-3.5 mu gihe cyo kumesa.

● Ibikoresho byinshi cyane

Amakuru y’igerageza agaragaza ko iyo ingano y’umutwaro irenze 15% by’umupaka wo hejuru, igipimo cyo gutakaza imyenda y’ipamba cyiyongera kikagera ku nshuro 2.3 z’agaciro gasanzwe.

Inzira zo gucunga (5%)

● Ikosa ryo gutondekanya ritera ibyuma by'amahanga bifite amahirwe ya 0.7 ‰

● Ingorane zo gutwara abantu zituma habaho impuzandengo ya 1.8 ku rugendo rumwe.

Impamvu eshatu zikunze kugaragara zitera kwangirika kw'imyenda. Ibi bibazo byose bishobora guhindurwa binyuze mu gucunga neza no gukoresha uburyo busanzwe bwo gukaraba. Ingingo ikurikira izagaragaza uburyo bwo kwirinda ibi bibazo.
