Hhayi kuphela lesikhumba isitatimende semfashini, futhi singumphumela wenqubo enhle yamakhemikhali eyaziwa ngokuthi ukushukunyiswa. Emkhakheni wokuphendula kwesikhumba, inqubo eyodwa ebalulekile iyaphela -ukumbungu Ake siqale uhambo oluhehayo lokuthola izimfihlo zokugcina, inqubo ebalulekile ekukhiqizeni kwesikhumba, futhi ihlole umhlaba omuhle wamakhemikhali wesikhumba.
1. Isayensi ngemuva kwesikhumba sesikhumba: Isikhumba sesikhumba yinqubo yokuguqula izilwane eziluhlaza ezifuywayo zibe nezinto eziqinile neziguquguqukayo. Le nqubo ifaka uchungechunge lokuphendula kwamakhemikhali aqinisa imicu e-collagen ngaphakathi kwesikhumba futhi ivikele ekuboleni. Ama-ejenti amakhemikhali akhethekile abizwa ngokuthi ama-retanning agents adlala indima ebalulekile kwinqubo yokudlala.
2. Thola ukuvuselelwa kabusha ngeAma-ejenti wokugcina: Ama-ejenti wokugcina izithako ezibalulekile ezisetshenziswa esigabeni sokugcina ukukhiqizwa kwesikhumba. Lawa ma-ejenti angukhiye wokudlulisela izakhiwo ezifiselekayo esikhumbeni esifana nokuthamba, ukuqina nokushesha kombala. Baphinde bathuthukise isisindo sabo sonke kanye namandla.
3. Kunezinhlobo eziningi zeAma-ejenti wokugcina: Ama-ejenti we-retanning aza ngezindlela ezahlukahlukene, ngalinye linomsebenzi othize. Ama-filler, anjenge-kaolin, asetshenziselwa ukugcwalisa izikhala ngaphakathi kwesakhiwo sesikhumba, enikeza ubushelelezi bokwaziswa kanye nokuthungwa. Ama-resins, njengama-acrylics, asiza ukuhlanganisa imicu ndawonye ukuze angezelwe amandla. Ama-FatLiquers, njengamafutha okwenziwa kanye nemvelo, gcoba lesikhumba futhi andise ukuguquguquka kwawo. Ngokwengeziwe, amakhompiyutha asuselwa ku-sulfur asetshenziselwa ukwenza lula i-polymerization yamakhemikhali wokugcina, ngaleyo ndlela akwazi ukuqina.
4. Ukucatshangelwa Kwezemvelo: Eminyakeni yamuva nje, imboni yesikhumba isukele ukugxila kwayo ekuhlelweni kwezinqubo zokukhiqiza ezizinzile nezinobungane. Ngentuthuko ngobuchwepheshe besikhumba, ama-ejenti wokuqashwa kwemvelo anjengezitsha zezitshalo namakhompiyutha we-biomimetic athole ukuthandwa ngenxa yomthelela wawo wokuncishiswa kwezemvelo. Laba bamele banciphisa ukukhishwa kwezinto eziyingozi emvelweni, okwenza isikhumba sikuthambekele ngokwengeziwe.
I-5. Hlangamela amazinga asezingeni Ukusetshenziswa ngokucophelela kwama-ejenti wokugcina kuqinisekisa ukuthi umkhiqizo wokugcina uhlangabezana nokucaciswa okufana nokufana kombala, ukuthamba kanye nokumelana nokushaywa noma ukudiliza. Amasu wokuhlaziya athuthukile, kufaka phakathi ukuskena i-elektroni microscopy kanye nokuhlaziywa kwe-spectroscopic, usizo lokuqinisekisa la mapharamitha ekhwalithi. Ekuphetheni: Umhlaba wesikhumba sesikhumba kanye nokugcina ukuthengiswa kuyinhlanganisela ekhangayo yobuciko, ubuciko kanye nokuqwashisa ngemvelo.
Njengoba imboni yesikhumba iyaqhubeka nokuvela, intuthuko kwezobuchwepheshe kanye nokwakheka kwamakhemikhali ithembisa ukuhlinzeka ngemikhiqizo yesikhumba esezingeni eliphakeme, esimeme. Ukuqonda izinkampani zokugcina kabusha nokuphendula kwayo kwamakhemikhali ezihambisana nakho ngeke nje kuthuthukiswe ukwazisa kwethu kwezimpahla zesikhumba kodwa futhi kuveze amandla amakhulu emboni yamakhemikhali wesikhumba. Ngokukhetha emhlabeni wamakhemikhali wesikhumba, sembula izimfihlo ezingemuva kokukhiqiza izimpaphe ezinhle ezihlanganisa ukuqina, ukuguquguquka nobuhle, ngenkathi kuhambisana nezidingo ezikhulayo zokusimama.
