Uma uthanda isikhwama, futhi incwadi ethi sebenzisa isikhumba, uthini okokuqala? Ikhwalithi ephezulu, ethambile, yakudala, ebiza kakhulu… Kunoma ikuphi, uma iqhathaniswa nezijwayelekile, inganika abantu umuzwa wokuqoka. Eqinisweni, ukusebenzisa i-100% yesikhumba sangempela kudinga ubunjiniyela obuningi ukucubungula izinto eziyisisekelo ezingasetshenziswa emikhiqizweni, ngakho intengo yezinto eziyisisekelo izoba phezulu.
Izinhlobonhlobo, ngamanye amazwi, isikhumba singabuye sihlukaniswe ngamamaki asezingeni eliphezulu nasezingeni eliphansi. Isici sokuqala esibaluleke kakhulu ekunqumeni leli banga 'isikhumba esiluhlaza'. 'Isikhumba soqobo' asikacutshungulwa, isikhumba sesilwane esiyiqiniso. Lokhu nakho kubalulekile, futhi lokho kubalulekile, kodwa akekho kubo ongaqhathanisa nekhwalithi yezinto zokusetshenziswa. Ngoba lesi sici sizothinta ikhwalithi yawo wonke umkhiqizo.
Uma sifuna ukushintsha isikhumba esiluhlaza sibe yimpahla yomkhiqizo, kufanele sidlule kunqubo ebizwa ngokuthi 'ukushukwa kwesikhumba'. Lokhu kubizwa nge-'Tanning' ngesiNgisi; yi-'제혁 ( tanning ) ' ngesi-Korean. Umsuka waleli gama kufanele kube 'tannin (tannin)', okusho izinto zokusetshenziswa ezitshalweni.
Isikhumba sesilwane esingakacutshungulwa sijwayele ukubola, izinambuzane, isikhunta nezinye izinkinga, ngakho-ke sicutshungulwa ngokuvumelana nenhloso yokusetshenziswa. Lezi zinqubo zibizwa ngokuhlanganyela ngokuthi " ukushukwa " . Nakuba ziningi izindlela zokushukwa, "isikhumba esishukiwe se-tannin" kanye "nesikhumba esishukiwe esi-chrome" zivame ukusetshenziswa. Ukukhiqizwa kwesikhumba ngobuningi kuncike kule ndlela ye-'chrome'. Eqinisweni, ngaphezu kwama-80% okukhiqizwa kwesikhumba kwenziwa 'ngesikhumba se-chrome'. Izinga lesikhumba esishukiwe semifino lingcono kunelesikhumba esivamile, kodwa ngesikhathi sokusetshenziswa, ukuhlolwa kuhlukile ngenxa yokungafani kokuthandwa komuntu siqu, ngakho ifomula ethi "isikhumba esishukiwe semifino = isikhumba esihle" ayifaneleki.Uma iqhathaniswa ne-chrome Isikhumba esishukiwe, isikhumba esishukiwe semifino siyahluka endleleni yokucubungula ngaphezulu.
Ngokuvamile, ukuqedwa kwesikhumba esishukiwe esine-chrome kuwukwenza ukucubungula okuthile ngaphandle; isikhumba esishukiwe semifino asidingi le nqubo, kodwa sigcina imibimbi yokuqala nokuthungwa kwesikhumba. Uma iqhathaniswa nesikhumba esijwayelekile, iqinile futhi iyaphefumula, futhi inezici zokuthamba ngokusetshenziswa. Kodwa-ke, mayelana nokusetshenziswa, kungase kube nokubi kakhulu ngaphandle kokucubungula. Ngenxa yokuthi ayikho ifilimu yokumboza, kulula ukuklwejwa nokungcoliswa, ngakho-ke kungase kube nzima ukuphatha.
Isikhwama noma isikhwama sokuchitha isikhathi esithile nomsebenzisi. Njengoba kungekho ukunamathela ebusweni besikhumba esishukiwe semifino, sinomuzwa othambile kakhulu njengesikhumba somntwana ekuqaleni. Nokho, umbala nokuma kwayo kuzoshintsha kancane ngenxa yezizathu ezifana nesikhathi sokusetshenziswa nezindlela zokugcina.
