Abantu abaningi bangase bathi lapho bebona ukufafaza okunamathelayo okungangeni manzi, ukufutha ukunamathela kulula kakhulu futhi akudingi incazelo nhlobo. Kodwa ingabe kunjalo ngempela?
Ukwakhiwa kokuvikela amanzi kwebhuloho kuhlukaniswe izingxenye ezimbili: ukuhlanzwa kwedekhi yebhuloho kanye nedeskithophu yebhuloho yokuvikela amanzi ngokufafaza.
Ingxenye yokuqala yokuhlanza ihlukaniswe ngokuqhunyiswa kwesibhamu (i-roughening) yedekhi yebhuloho kanye nokuhlanza isisekelo. Asikhulume ngalesi sihloko okwamanje.

Ukufafaza okunamathelayo okungangeni manzi kuhlukaniswe ngezinyathelo ezimbili: isifutho sedekhi yebhuloho engangeni manzi kanye nomdwebo wendawo.
Lapho ufafaza i-deck yebhuloho engangeni manzi okokuqala ngqa, inani elithile lesisombululo se-surfactant kufanele lengezwe embotsheni ukuze lihlanjululwe ukuze kuthuthukiswe ukungena kwe-coating kuma-capillary pores of the base layer futhi kuthuthukise amandla okubopha namandla okugunda. ukunamathela emanzini. Uma ufutha ijazi lesibili, lesithathu, nelesine likapende, linda kuze kube yilapho ijazi langaphambilini likapende lome ngokuphelele ngaphambi kokufutha.
Ingxenye yokudweba iwukuvimbela upende ukuthi ungangcolisi udonga oluvimbela ukushayisana. Lapho ufutha idekhi yebhuloho engangeni manzi, othile kufanele abambe indwangu ukuze avikele udonga oluvimbela ukushayisana. Okunconyiwe: Ngenxa yongqimba olungangenwa amanzi ngaphansi kodonga oluvimbela ukushayisana, ngokuvamile kuyanconywa ukusebenzisa umdwebo owenziwe ngesandla ukuze upende ingxenye.
Kuthiwani ngobuchwepheshe bokwakha bokufafaza idekhi yebhuloho engangeni manzi? Ngemva kokufunda okuqukethwe ngenhla, ingabe usacabanga ukuthi kuwumsebenzi olula?
