Ayisiyonto yesikhumba kuphela inkcazo yefashoni, ikwasisiphumo senkqubo entle yeekhemikhali eyaziwa ngokuba kukushuka. Kwinkalo yeekhemikhali zesikhumba, enye inkqubo ephambili igqamile-ukutshisa Masiqalise uhambo olunomdla lokufumana iimfihlo zokuphinda uluthwe, inkqubo edibeneyo kwimveliso yesikhumba, kwaye sijonge ilizwe elimangalisayo lekhemistri yesikhumba.
1. Inzululwazi ngokusulwa kwesikhumba: Ukusukwa kwesikhumba yinkqubo yokuguqula izikhumba zezilwanyana ezikrwada zibe yimathiriyeli eyomelele kwaye ebhetyebhetye. Le nkqubo ibandakanya uchungechunge lweempendulo zemichiza ezizinzisa iifayili ze-collagen ngaphakathi kwesikhumba kwaye zikhusele ukuba zingaboli. Iiarhente zeekhemikhali ezikhethekileyo ezibizwa ngokuba zii-retanning agents zidlala indima ebalulekileyo kwinkqubo yokwenziwa ngokutsha.
2. Ukutyhila ukuvuselelwa ngeiiarhente zokutshisa: Ii-ajenti zokucoca zizithako ezibalulekileyo ezisetyenziswa kwibakala lokuntshula kwimveliso yesikhumba. Ezi arhente zingundoqo ekunikeni iimpawu ezinqwenelekayo kwesikhumba njengokuthamba, ukuqina kunye nokukhawuleza kombala. Bakwaphucula ubunzima bayo bonke kunye namandla.
3. Kukho iintlobo ezininziiiarhente zokutshisa: Iiarhente ezihlaziyayo ziza ngeendlela ezahlukeneyo, nganye inomsebenzi othile. Izihluzi, ezifana ne-kaolin, zisetyenziselwa ukugcwalisa izithuba ngaphakathi kwesakhiwo sesikhumba, ukunika izinto eziphathekayo kunye nokuthungwa. I-resins, efana ne-acrylics, inceda ukudibanisa iifayili ndawonye ukuze zibe namandla. I-Fatliquors, njenge-synthetic kunye neoli yendalo, ithambisa isikhumba kwaye yandise ukuguquguquka kwayo. Ukongezelela, iikhompawundi ezisekelwe kwisulfure zisetyenziselwa ukuququzelela i-polymerization yeekhemikhali ezihlaziyayo, ngaloo ndlela zandisa ukuqina.
4. Iingqwalasela zokusingqongileyo: Kwiminyaka yakutsha nje, ishishini lesikhumba liye latshintsha ingqwalasela yalo yaya kwiinkqubo zokwenziwa ezizinzileyo nezilungele ukuphilisana kwendalo. Ngokuhambela phambili kwitekhnoloji yesikhumba, ii-ejenti zokulukwa kwendalo ezifana nezicatshulwa zezityalo kunye neekhompawundi ze-biomimetic ziye zafumana ukuthandwa ngenxa yokuncipha kwempembelelo yazo kokusingqongileyo. Ezi arhente zinciphisa ukukhutshwa kwezinto ezinobungozi kokusingqongileyo, zenza ukusukwa kwesikhumba kube yinto ezinzileyo.
5. Ukuthobela imigangatho yomgangatho: Iimveliso zesikhumba zivavanywa ngokuqatha kwaye zihlangabezana nemigangatho yamazwe ngamazwe. Ukusetyenziswa ngononophelo kweearhente zokutshisa iqinisekisa ukuba imveliso yokugqibela idibana neenkcukacha ezinqwenelekayo ezifana nokungaguquguquki kombala, ukuthamba kunye nokumelana nokukrwela okanye ukukrazuka. Ubuchule bokuhlalutya obuphezulu, kubandakanywa ukuskena i-electron microscopy kunye nohlalutyo lwe-spectroscopic, uncedo ekuqinisekiseni ezi parameters zomgangatho. Ukuqukumbela: Ilizwe lokusukwa kwesikhumba kunye nolwethu ngokutsha yindibaniselwano enika umdla yokugqwesa kwezenzululwazi, ubugcisa kunye nokwazisa ngendalo esingqongileyo.
Njengoko ishishini lesikhumba liqhubeka nokuguquka, ukuqhubela phambili kwezobuchwepheshe kunye nokwakhiwa kweekhemikhali kuthembisa ukubonelela ngomgangatho ophezulu, iimveliso zesikhumba ezizinzileyo. Ukuqonda izinto ezintsonkothileyo zokwenziwa ngokutsha kwesikhumba nendibaniselwano yemichiza eyayanyaniswa nayo akusayi kwandisa nje uxabiso lwethu ngempahla yothwathwa kodwa kwakhona kutyhila amandla amakhulu oshishino lwemichiza yesikhumba. Ngokuphonononga kwihlabathi lekhemistri yesikhumba, sityhila iimfihlo ezingemva kokuvelisa amafele amahle aquka ukuqina, ukuguquguquka kunye nobuhle, ngelixa sigcina isantya sokukhula kweemfuno zozinzo.
