Abazali abaningi bakhetha ukuthenga izingane zabo izicathulo zekhwalithi. Iphuzu elibuthakathaka lezinhlobo eziningi, njengomthetho, ukushisa okunganele ngokwanele kwemilenze yezingane nokuvimbela esimweni sezulu sezulu noma ngesikhathi seqhwa. Kodwa impilo yezimpumputhe incike ngqo. Kodwa yiyiphi inyane lezinyane elizolikhanyela ukunqanda emahlathini noma ukuhlola i-snowdrift ebaleni lokudlala? Ngakho-ke, abazali abaningi banakekelwa izicathulo ezibizwa nge-membrane. Ukuthandwa kwalo kukhula nsuku zonke. Kodwa yikuphi ubuchwepheshe bezingubo zokukhwabanisa, ukugqoka nokuzinakekela kanjani?
Isimiso sokusebenza kwezicathulo ze-membrane
Lolu hlobo "lwezingubo" zomilenze lwenziwa ngokusebenzisa ubuchwepheshe obukhethekile ngokusetshenziswa kwebhande, okungukuthi, ifilimu encane kakhulu yezinto ezibonakalayo ze-polymeric microporous. Kodwa lokhu akulona uhla olulodwa kuphela ezicathulweni zezingqimba zezingane. Umkhiqizo unamabhodlela afudumele (uboya, ubuningi bokufakelwa noma i-mesh fabric), i-membrane ngokwayo kanye nengubo ephezulu (i-textile, isikhumba). Izimbobo ezitsheni ze-membrane gasket zincane kakhulu kangangokuthi azivumeli ama-molecule amanzi aphuluke, ngakho-ke unyawo alutholi manzi. Ama-molecule emiphuphu yamanzi amancane kunezingqinamba zekhanda, ukujuluka kukhishwa ngokugcwele, okusho ukuthi umlenze wengane usulele, ngoba umswakama awunamatheli ebhokisini. Nokho, lezi zimfanelo zezingqimba zebusika zezingane zisebenza kuphela uma ingane iselula. Kubalulekile futhi ukugqoka amasokisi ebantwaneni hhayi kusuka kwikotini, okubamba ukukhukhumeza ngokugcwele, kodwa kusuka emicongweni yokwenza noma ama-thermoswitches.
Imikhiqizo ethandwa kunazo zonke zezingubo zokushisa zebusika zezingane yi-Viking yaseNorway, i-Ricostasta yaseJalimane, i-Austrian Superfit, i-Danish ECCO, i-Rein Finnish, i-Italian Scandia. Ungakwazi ukubona izicathulo zezinhlamvu ngokubhalwe kwilebula layo i-Sympatex, i-Gore-Tex noma i-tec.
Ukunakekela izicathulo ze-membrane
Uma uhlose ukuthenga lezo zicathulo kumntanakho othandekayo, kufanele uzijwayele ngemithetho yokunakekela izicathulo zezingqimba, ngaphandle kwalokho zizolahlekelwa yizindawo zayo. Ngakho-ke, uma kwenzeka, uma kwenzeka ukungcoliswa, imikhiqizo yesikhumba ihlanzwa ngamanzi afudumele ngebhashishi, futhi isiponji se-textile igxilile emanzini noma emanzini asozini.
Ngokuphathelene nokomisa izicathulo ze-membrane, konke kuqinisiwe lapha: akuvunyelwe ukusebenzisa amasheya noma amabhethri okushisa okuphakathi, ngaphandle kwalokho i-membrane izoshukela. Vele ushiye izicathulo noma amabhuzu ekamelweni lokushisa noma ushayele ephephandabeni, ngezikhathi ezithile uziguqule.
Izitshalo kufanele ziphathwe ngemuva kokuma. Kukhona ukhilimu wezicathulo ze-membrane, ezinamakhemikhali ahlanzekile amanzi. Uma phezulu kwenziwa ngezindwangu, ukufakwa okukhethekile kuyadingeka, okuvimbela nokumamatheka kwamanzi. Uma ulandela imithetho yokusetshenziswa nokunakekelwa, izicathulo zekhanda zizofudumala imilenze yengane yakho.
