Ubwiza-bwizakashe yo kubakaGira uruhare runini mukubaka kubungabunga no kuramba. Mu bwoko butandukanye bwubwubatsi buboneka, kashe ya polyurethane, izwi kandi nka PU kashe, igaragara nkicyifuzo gikunzwe kubera imiterere yihariye kandi itandukanye.
Ikidodo c'ubwubatsi ni ngombwa mu kurinda inyubako ibintu bidukikije nk'amazi, umwuka, n'umukungugu. Bashyiraho inzitizi ibuza ubushuhe kwinjira mu nyubako, bishobora gutera kwangirika kwimiterere no gukura. Byongeye kandi, kashe zifasha kuzamura ingufu zingirakamaro zifunga icyuho n’ibice, bityo bikagabanya imyuka ihumeka nubushyuhe.
Ku bijyanye no gushiraho kashe, kashe ya polyurethane yubahwa cyane kubiramba kandi byoroshye. Ikidodo cya PU kizwiho guhuza neza ibikoresho byinshi, birimo beto, ibiti, ibyuma, na plastiki. Ubu buryo butandukanye butuma bikenerwa mubikorwa bitandukanye, kuva gufunga ingingo hamwe nu cyuho mumadirishya ninzugi kugeza kuzuza ibice byubatswe.
Gukoresha kashe ya polyurethane yo mu rwego rwo hejuru ni ngombwa kugirango habeho gukora neza inyubako. Ikidodo cyo hasi gishobora guteshwa agaciro mugihe, biganisha ku gucikamo icyuho kibangamira ubusugire bwinyubako. Ku rundi ruhande, kashe ya PU yo mu rwego rwo hejuru itanga uburinzi burambye kandi irashobora kwihanganira ibihe bibi by’ikirere, imishwarara ya UV, n’imihindagurikire y’ubushyuhe.
Usibye kubirinda, kashe ya polyurethane igira uruhare mubwiza rusange bwinyubako. Ziboneka mumabara atandukanye kandi zirashobora gusiga irangi byoroshye kugirango zihuze ninyuma yinyubako, zitanga umusozo utagira ikidodo kandi usize neza. Gukoresha neza kashe yubaka, cyane cyane kashe ya polyurethane, bisaba kwitondera amakuru arambuye no kubahiriza amabwiriza yabakozwe. Ni ngombwa gutegura ubuso neza kandi ugashyiraho kashe kugirango ubashe gukora neza.
Mu gusoza, akamaro ko gukoresha kashe nziza yo kubaka, cyane cyane kashe ya polyurethane, ntishobora kuvugwa. Ikidodo ningirakamaro mukubungabunga inyubako, gutanga uburinzi kubushuhe, kuzamura ingufu, no kuzamura isura rusange yimiterere. Gushora imari muri kashe ya PU nicyemezo cyubwenge cyo kwemeza kuramba no gukora neza kwinyubako.
