Akukhona nje ukuthi isikhumba siyisitatimende semfashini, siphinde sibe umphumela wenqubo enhle yamakhemikhali eyaziwa ngokuthi ukushuka.Emkhakheni wokuphendula kwamakhemikhali esikhumba, inqubo eyodwa ebalulekile igqamayo -ukushuka kabusha Masingene ohambweni oluhehayo lokuthola izimfihlo zokushuka kabusha, inqubo ebalulekile ekukhiqizweni kwesikhumba, futhi sihlole umhlaba omangalisayo wekhemistri yesikhumba.
1. Isayensi yokushuka kwesikhumba: Ukushuka kwesikhumba kuyinqubo yokuguqula izikhumba zezilwane ezingavuthiwe zibe izinto ezihlala isikhathi eside nezivumelana nezimo.Le nqubo ihilela uchungechunge lokusabela kwamakhemikhali ezinzisa imicu ye-collagen ngaphakathi kwesikhumba futhi ivimbele ukuthi ingaboli.Ama-agent akhethekile amakhemikhali abizwa ngokuthi ama-retanning adlala indima ebalulekile enqubweni yokushuka kabusha.
2. Yembula ukuvuselelwa ngeama-retanning agents: Ama-retanning agents ayizithako ezibalulekile ezisetshenziswa esigabeni sokushuka kabusha sokukhiqizwa kwesikhumba.Lawa ma-ejenti ayisihluthulelo sokunikeza izinto ezifiselekayo esikhumbeni njengokuthambile, ukunwebeka nokushesha kombala.Baphinde bathuthukise ubukhulu bayo kanye namandla.
3. Kunezinhlobo eziningi zeama-retanning agents: Ama-ejenti avuselelayo afika ngezindlela ezihlukene, ngalinye linomsebenzi othile.Izihlungi, njenge-kaolin, zisetshenziselwa ukugcwalisa izikhala ezingaphakathi kwesakhiwo sesikhumba, okwenza izinto zibe bushelelezi nokuthungwa.Ama-resin, njengama-acrylics, asiza ukuhlanganisa imicu ndawonye ukuze uthole amandla engeziwe.Ama-fatliquors, njengamafutha okwenziwa nawemvelo, agcoba isikhumba futhi andise ukuguquguquka kwaso.Ukwengeza, ama-compounds asekelwe kwisulfure asetshenziselwa ukwenza i-polymerization yamakhemikhali avuselelayo, ngaleyo ndlela andise ukuqina.
4. Ukucatshangelwa kwemvelo: Eminyakeni yamuva nje, imboni yesikhumba ishintshe ukugxila kwayo kuzinqubo zokukhiqiza ezisimeme futhi ezinobungani nemvelo.Ngokuthuthuka kwezobuchwepheshe besikhumba, ama-ejenti okushuka kwemvelo afana nezitshalo ezikhishwe kanye nezinhlanganisela ze-biomimetic athole ukuduma ngenxa yokuncipha komthelela wazo kwezemvelo.Lawa ma-ejenti anciphisa ukukhishwa kwezinto eziyingozi endaweni ezungezile, okwenza ukushuka kwesikhumba kube umkhuba osimeme.
5. Namathela ezindinganisweni zekhwalithi: Imikhiqizo yesikhumba ihlolwa ikhwalithi eqinile futhi ihlangabezana nezindinganiso zamazwe ngamazwe.Ukusetshenziswa ngokucophelela kwezinto ezibuyisela ukushuka kuqinisekisa ukuthi umkhiqizo wokugcina uhlangabezana nezimfuneko ezifiselekayo ezifana nokungaguquguquki kombala, ukuthamba kanye nokumelana nokunwaya noma ukuklebhuka.Amasu okuhlaziya athuthukile, okuhlanganisa ukuskena i-electron microscopy nokuhlaziywa kwe-spectroscopic, asiza ukuqinisekisa le mingcele yekhwalithi.ekuphetheni: Umhlaba wokushuka nokushukwa kabusha kwesikhumba uyinhlanganisela ethokozisayo yobuhle besayensi, ubuciko nokuqwashisa ngemvelo.
Njengoba imboni yesikhumba iqhubeka nokuthuthuka, intuthuko kwezobuchwepheshe kanye nokwakheka kwamakhemikhali ithembisa ukuhlinzeka ngemikhiqizo yesikhumba esezingeni eliphezulu, eqhubekayo.Ukuqonda ubunkimbinkimbi bokushuka futhi nokuhambisana nakho kwamakhemikhali ngeke nje kuthuthukise ukwazisa kwethu impahla yesikhumba kodwa futhi kwembule amandla amakhulu emboni yamakhemikhali esikhumba.Ngokuhlola umhlaba wekhemikhali yesikhumba, sembula izimfihlo zokukhiqiza izikhumba ezinhle ezihlanganisa ukuqina, ukuguquguquka nobuhle, kuyilapho sihambisana nezidingo ezikhulayo zokusimama.
