Mbiri yaukadaulo wofufuta zikopa imachokera ku chitukuko cha ku Egypt chakale mu 4000 BC. Pofika m’zaka za m’ma 1800, umisiri watsopano wotchedwa chromium kutentha kwa kutentha unathandiza kwambiri kuti ntchito yowotchera zikopa ikhale yothandiza kwambiri ndipo inasintha kwambiri ntchito yofufuta. Pakali pano, kufufuta kwa chrome ndiyo njira yodziwika kwambiri yofufutira yomwe imagwiritsidwa ntchito padziko lonse lapansi.

Ngakhale kuwotcha kwa chrome kuli ndi zabwino zambiri, zinyalala zambiri zimapangidwa panthawi yopanga, zomwe zimakhala ndi ayoni azitsulo zolemera monga ma chromium ions, omwe amatha kuwononga chilengedwe komanso thanzi la anthu. Chifukwa chake, ndikuwongolera kuzindikira kwachilengedwe kwa anthu komanso kulimbikitsa malamulo mosalekeza, ndikofunikira kupanga zowotcha zobiriwira.

DECISION yadzipereka kuti ifufuze njira zothanirana ndi chilengedwe komanso zikopa zobiriwira. Tikuyembekeza kufufuza limodzi ndi ogwira nawo ntchito kuti apange chikopa chotetezeka.

GO-TAN chromium-free danning system

Dongosolo lotenthetsera organic lobiriwira linatuluka ngati yankho ku zofooka ndi zovuta zachilengedwe za chikopa cha chrome:

GO-TAN chromium-free danning system
ndi njira yobiriwira yowotchera organic mwapadera kuti azitentha zikopa zamitundu yonse. Ili ndi ntchito yabwino kwambiri ya chilengedwe, ilibe zitsulo, ndipo ilibe aldehyde. Njirayi ndi yosavuta ndipo sikutanthauza pickling ndondomeko. Zimathandizira kwambiri kufufuta ndikuwonetsetsa kuti zinthu zili bwino.

Pambuyo poyesedwa mobwerezabwereza ndi gulu laukadaulo la Decision ndi gulu la R&D, tafufuzanso zambiri pakuwongolera ndi kuwongolera njira yowotcha. Kupyolera mu njira zosiyanasiyana zoyendetsera kutentha, timaonetsetsa kuti kutentha kwabwino kumakhala koyenera.

Kuyambira pa ubale wa hydrophilic (wothamangitsa) katundu wa retanning wothandizila ndi katundu wa chikopa chonyowa choyera, ndipo kutengera zofunika zosiyanasiyana makasitomala osiyanasiyana chikopa ntchito ndi khalidwe, ife anakonza zosiyanasiyana retanning dongosolo kuthandiza njira zomwe ndi zoyenera kwambiri kwa makasitomala. Zothetsera izi sizongofunika Kuwongolera magwiridwe antchito ndi mawonekedwe achikopa, komanso kumalemeretsa kwambiri mzere wazinthu zathu kuti zikwaniritse zosowa za makasitomala osiyanasiyana.

Dongosolo lachigamulo la GO-TAN lopanda chrome lopanda zikopa ndiloyenera mitundu yosiyanasiyana ya zikopa, kuphatikiza chikopa chapamwamba cha nsapato, chikopa cha sofa, chikopa cha suede, chikopa chagalimoto, ndi zina zambiri. Kupyolera mu kuyesa kwakukulu ndi kafukufuku wogwiritsa ntchito, tawonetsa zotsatira za GO. -TAN chromium-free porning system on chikopa ngatinso kufufuta, zomwe zimatsimikizira bwino kuti dongosololi ndilabwino komanso likugwiritsidwa ntchito.
