Iingcebiso zesisombululo
Yonke indlela eya kwihlabathi 'elingenayo i-formaldehyde'
Isindululo seemveliso ze-amino resin zeSigqibo
Impembelelo ebangelwa yi-formaldehyde yamahhala eveliswa ngexesha lenkqubo yokutshisa ikhankanyiwe yi-tanneries kunye nabathengi ngaphezu kweminyaka elishumi edlulileyo. Nangona kunjalo kuphela kwiminyaka yakutshanje lo mbandela uthatyathwe nzulu ngabasuki.
Kuzo zombini ii-tanneries ezinkulu nezincinci, ugxininiso luye lwatshintshela kuvavanyo lomxholo wasimahla we-formaldehyde. Ezinye ii-tanneries ziya kuvavanya yonke ibhetshi yesikhumba sabo esandula ukuveliswa ukuqinisekisa ukuba iimveliso zabo zisemgangathweni.
Kubantu abaninzi kwishishini lesikhumba, ukuqonda indlela yokuthoba umxholo we-formaldehyde yasimahla kwisikhumba yenziwe yacaca gca——
Ii-amino resin tanning agents ezimelwe ikakhulu yi-melamine kunye ne-dicyandiamide, zingowona nobangela wokuveliswa kwe-formaldehyde yasimahla kwinkqubo yokwenza ufele kunye nokukhutshwa rhoqo kwe-formaldehyde kumanqaku esikhumba. Ke ukuba iimveliso ze-amino resin kunye neempembelelo zasimahla ze-formaldehyde abazizisayo zinokulawulwa ngokupheleleyo, idatha yovavanyo yasimahla ye-formaldehyde inokulawulwa ngokufanelekileyo. Singatsho ukuba iimveliso ze-amino resin ziyimbangela yeengxaki ze-formaldehyde zamahhala ngexesha lenkqubo yokwenza isikhumba.
Isigqibo sele sisenza iinzame zokuvelisa i-formaldehyde amino resins kunye ne-formaldehyde-free amino resins. Uhlengahlengiso ngokubhekiselele kwimiba yomxholo we-formaldehyde kunye nokusebenza kwee-agent zokutshisa zihlala zisenziwa.
Ngokuqokelelwa kwexesha elide lolwazi, amava, ukusungula izinto ezintsha, uphando kunye nophuhliso. Okwangoku, uyilo lwethu lwemveliso engena-formaldehyde luphelele. Iimveliso zethu bezineziphumo ezinqwenelekayo, kokubini malunga nokuhlangabezana nemfuno ye-'zero formaldehyde' kunye nokutyebisa kunye nokuphucula ukusebenza kweearhente zolusu.

Izixhobo zokuthambisa i-dicyandiamide ezingena-formaldehyde
Ibonelela ngeenkozo eziqinileyo neziqinile
Uphuhliso oluzinzileyo lube yinxalenye ebaluleke kakhulu kwishishini lesikhumba, indlela eya kuphuhliso oluzinzileyo isekude kwaye igcwele imingeni.
Njengeshishini elinoxanduva siya kukuphatha oku njengesibophelelo kwaye sisebenze ngokuzingisileyo nangokunganikezeli kwinjongo yokugqibela.
