Ngenxa yokuqina nokubukeka kwakudala, isikhumba besilokhu siyisinqumo esithandwayo semfashini, ifenisha kanye nezesekeli. Nokho, eminyakeni yamuva nje, kuye kwavela oqhudelana naye omusha ngesikhumba se-PU. Kodwa siyini ngempela isikhumba se-PU? Ihluke kanjani kunesikhumba sangempela? Kulesi sihloko, sizongena phakathi kwezici kanye nomehluko phakathi kwalokhu kokubili.
Isikhumba se-PU, eyaziwa nangokuthi isikhumba sokwenziwa noma isikhumba se-faux, imele isikhumba se-polyurethane. Kuyinto yokwenziwa elingisa ukubukeka nokuzwakala kwesikhumba sangempela. Ngokungafani nesikhumba sangempela, esenziwe ngezikhumba zezilwane, isikhumba se-PU senziwe kusetshenziswa inhlanganisela ye-polyurethane coatings esetshenziswa ezintweni eziyisisekelo (imvamisa indwangu efana ne-polyester noma ukotini). Lokhu kunamathela kudala ukuthungwa okufana kakhulu nesikhumba sangempela.
Enye yezinzuzo eziyinhloko ze-PU lesikhumba ukufinyeleleka kwayo.Ngenxa yenqubo yokukhiqiza kanye nokungabikho kwezikhumba zezilwane, isikhumba se-PU sishibhile kakhulu ukukhiqiza kunesikhumba sangempela. Lokho kwenza kube ukukhetha okuphezulu kulabo abafuna ukubukeka okuhle nokuzizwa kwesikhumba ngaphandle kokukhokha ithegi yentengo ephakeme.
Ngaphezu kwalokho, isikhumba se-PU sinokumelana kwamanzi okuphakeme nokumelana nokunwaya uma kuqhathaniswa nesikhumba sangempela. Ngokuvamile kubhekwa njengokuhlala isikhathi eside futhi kulula ukuyigcina njengoba ingahlanzwa ngendwangu emanzi. Isikhumba sangempela, ngakolunye uhlangothi, sidinga ukunakekelwa okukhethekile kanye ne-conditioning ukuze sigcine sibukeka kahle kakhulu.
Kodwa-ke, kukhona futhi umehluko omkhulu phakathi kwesikhumba se-PU nesikhumba sangempela. Umehluko ophawuleka kakhulu ukwakheka kwazo. Isikhumba sangempela sitholakala esikhumbeni sesilwane futhi siyinto yemvelo. Inezici eziyingqayizivele ezifana nokuphefumula, ukuguquguquka nobudala obuhle ngokuhamba kwesikhathi. Isiqephu ngasinye sesikhumba sangempela sinezimpawu zayo ezihlukile, ezengeza ebuhleni nasebuntwini baso.
Ngokuphambene, isikhumba se-PU asinazo lezi zakhiwo zemvelo. Ayiphefumuli futhi ayizwakali uma iqhathaniswa nesikhumba sangempela. Ngokuhamba kwesikhathi, isikhumba se-PU singase futhi sibonise izimpawu zokuqhekeka noma ukuxebuka ekugugile. Ngesikhumba sangempela, lokhu akuyona inkinga njengoba ithuthukisa i-patina ethuthukisa ukukhanga kwayo nokunwebeka.
Okunye okucatshangelwayo okubalulekile lapho ukhetha phakathi kwesikhumba se-PU kanye nesikhumba sangempela ukusimama. Isikhumba se-PU sivame ukubhekwa njengento enobungani bemvelo ngoba ayidingi izikhumba zezilwane. Ingakhiqizwa ngendlela elawulwayo neqhubekayo. Kodwa-ke, isikhumba sangempela siphakamise ukukhathazeka ngenhlalakahle yezilwane kanye nomthelela wemvelo wemboni yenyama.
Sengiphetha, isikhumba se-PU siyindlela yokwenziwa yesikhumba sangempela eklanyelwe ukulingisa ukubukeka nokuthungwa kwayo. Iyathengeka, ayinamanzi futhi kulula ukuyinakekela. Ngakolunye uhlangothi, isikhumba sangempela sinezimfanelo eziyingqayizivele njengokuphefumula nokuguga okujabulisayo. Ekugcineni, ukukhetha phakathi kwalokhu okubili kwehlela ekuthandeni komuntu siqu, isabelomali, nokucatshangelwa kokuziphatha.
