Isikhumba asigcini nje ngokuba yisitayela semfashini, kodwa futhi siwumphumela wenqubo yamakhemikhali enhle eyaziwa ngokuthi ukushiswa kwesikhumba. Emkhakheni wokusabela kwamakhemikhali esikhumba, inqubo eyodwa ebalulekile iyagqama -ukushiswa kwesikhumba kabusha Ake siqale uhambo oluthakazelisayo lokuthola izimfihlo zokuphinda sishise isikhumba, inqubo ebalulekile ekukhiqizweni kwesikhumba, nokuhlola umhlaba omangalisayo wekhemikhali yesikhumba.
1. Isayensi ngemuva kokushiswa kwesikhumba: Ukushiswa kwesikhumba inqubo yokuguqula izikhumba zezilwane ezingavuthiwe zibe izinto eziqinile neziguquguqukayo. Le nqubo ihilela uchungechunge lwezindlela zamakhemikhali eziqinisa imicu ye-collagen ngaphakathi kwesikhumba futhi zivimbele ukubola. Ama-chemical agent akhethekile abizwa ngokuthi ama-retanning agents adlala indima ebalulekile enkambisweni yokushiswa kwesikhumba.
2. Thola ukuvuselelwa kabusha ngeizinto zokubopha i-tan: Izinto zokwenza isikhumba sithambe kabusha ziyizithako ezibalulekile ezisetshenziswa esigabeni sokwenza isikhumba sithambe kabusha ekukhiqizweni kwesikhumba. Lezi zinto ziyisihluthulelo sokunikeza izakhiwo ezifiselekayo esikhumbeni njengokuthamba, ukuguquguquka kanye nokuqina kombala. Ziphinde zithuthukise ubukhulu baso kanye nokuqina.
3. Kunezinhlobo eziningi zeizinto zokubopha i-tan: Ama-retanning agents eza ngezindlela ezahlukene, ngayinye inomsebenzi wayo othize. Ama-filler, njenge-kaolin, asetshenziselwa ukugcwalisa izikhala ngaphakathi kwesakhiwo sesikhumba, okwenza izinto zibe bushelelezi futhi zibukeke kahle. Ama-resin, njenge-acrylics, asiza ukuhlanganisa imicu ndawonye ukuze kube namandla engeziwe. Ama-fatliquors, njengamafutha okwenziwa kanye nawemvelo, agcoba isikhumba futhi andise ukuguquguquka kwaso. Ngaphezu kwalokho, ama-compounds asekelwe esibabule asetshenziselwa ukwenza kube lula ukwenza i-polymerization yamakhemikhali aretanning ibe mnyama, ngaleyo ndlela andise ukuqina.
4. Ukucabangela imvelo: Eminyakeni yamuva nje, imboni yesikhumba ishintshele ekugxileni kwayo ezinqubweni zokukhiqiza ezisimeme nezinobungani nemvelo. Ngokuthuthuka kobuchwepheshe besikhumba, izinto zokwenza isikhumba sibe nombala ofana nezingcezu zezitshalo kanye nezinto ezibizwa nge-biomimetic ziye zathandwa ngenxa yokuncipha komthelela wazo kwezemvelo. Lezi zinto zenza isikhumba sibe mnandi kakhulu, okwenza isikhumba sibe mnandi kakhulu.
5. Landela amazinga ekhwalithi: Imikhiqizo yesikhumba ihlolwa ikhwalithi eqinile futhi ihlangabezana nezindinganiso zomhlaba wonke. Ukusetshenziswa ngokucophelela kwama-retanning agents kuqinisekisa ukuthi umkhiqizo wokugcina uhlangabezana nezindinganiso ezifunwayo njengokuvumelana kombala, ubumnene kanye nokumelana nokuklwebheka noma ukudabuka. Amasu okuhlaziya athuthukisiwe, okuhlanganisa ukuskena i-electron microscopy kanye nokuhlaziywa kwe-spectroscopic, kusiza ukuqinisekisa lezi zilinganiso zekhwalithi. ekuphetheni: Umhlaba wokushiswa kwesikhumba kanye nokushiswa kwesikhumba kuyinhlanganisela ethakazelisayo yobuhle besayensi, ubuciko kanye nokuqwashisa ngemvelo.
Njengoba imboni yesikhumba iqhubeka nokuthuthuka, intuthuko kwezobuchwepheshe kanye nokwakheka kwamakhemikhali ithembisa ukuhlinzeka ngemikhiqizo yesikhumba esezingeni eliphezulu neqhubekayo. Ukuqonda ubunzima bokushiswa kwesikhumba kanye nokusabela kwamakhemikhali okuhambisana nakho ngeke kuthuthukise nje kuphela ukwazisa kwethu izimpahla zesikhumba kodwa futhi kuzoveza amandla amakhulu embonini yamakhemikhali esikhumba. Ngokuhlola umhlaba wekhemikhali yesikhumba, sembula izimfihlo ngemuva kokukhiqiza izikhumba ezinhle ezibonisa ukuqina, ukuguquguquka kanye nobuhle, ngenkathi sihambisana nezidingo ezikhulayo zokusimama.
