Njira yopenda zikopaNdi gawo lofunikira kwambiri pakusintha nyama imabisala mu zinthu zokhazikika, zokhazikika zomwe zingagwiritsidwe ntchito pazitsulo zosiyanasiyana, kuchokera ku zovala ndi nsapato kwa mipando ndi zowonjezera. Zida zophatikizira zomwe zimagwiritsidwa ntchito poyang'ana gawo lofunikira posankha mtundu ndi katundu wa zikopa zomalizidwa. Kumvetsetsa zinthu zosiyanasiyana zopangira zomwe zimakhudzidwa ndi njira yopepuka ndikofunikira kuti aliyense azichita zikopa.
Chimodzi mwazinthu zopangira zikwangwani zomwe zimagwiritsidwa ntchito potunga zikopa ndi nyama zimabisala zokha. Abizinesi nthawi zambiri amapezeka kuchokera ku nyama monga ng'ombe, nkhosa, mbuzi, ndi nkhumba, zomwe zimaleredwa chifukwa cha nyama zawo komanso zinthu zina. Khalidwe la hides limakhudzidwa ndi zinthu monga mtundu, m'badwo, ndi momwe zidaleredwera. Amabisala ndi zilema zochepa komanso zokutira zambiri nthawi zambiri zimakonda kupanga zikopa.
Kuphatikiza pa zikopa za nyama, matupi a nyama amagwiritsanso ntchito mankhwala osiyanasiyana komanso zinthu zachilengedwe kuti muthandizire njira yofufuta. Chimodzi mwazinthu mwazipembedzo zachikhalidwe kwambiri ndi Tannin, chojambulachi mwachilengedwe chomwe chimapezeka muzomera monga Oak monga Oak, Chestnut, ndi Quebracho. Tannin amadziwika kuti amatha kumangirira ulusi wa collagen mu chikopa cha nyama, ndikupereka chikopa chawo mphamvu, kusinthasintha, ndi kukana kuvunda. Tenneries ikhoza kupeza Tannin pochotsa zida zomera zaiwisi kapena pogwiritsa ntchito malonda a Tonan.
Wothandizira wina wamba ndi mchere wa chromium, womwe umagwiritsidwa ntchito kwambiri popanga zamakono. Cromium, celmium amadziwika kuti liwiro lake ndi kuchita bwino, komanso kuthekera kwake kutulutsa zofewa, zowonjezera zikopa zabwino kwambiri. Komabe, kugwiritsa ntchito chromium potayika kumayambitsa mavuto azachilengedwe chifukwa cha kuthekera kwa zinyalala zowopsa ndi kuipitsa. Tenneries iyenera kutsatira malamulo okhwima komanso machitidwe abwino kuti muchepetse chilengedwe cha chromium.
Zinthu zina zamankhwala zomwe zimagwiritsidwa ntchito pofufuta zimaphatikiza acid, zitsulo, ndi zokongoletsa zosiyanasiyana. Mankhwalawa amathandizira kuchotsa tsitsi ndi mtsinje wa chibile, sinthani Ph la yankho lofufuta, ndikuwongolera kumanga kwa tannins kapena chromium to fiberment. Tenyani ayenera kuthana ndi mankhwalawa mosamala kuti atsimikizire chitetezo chantchito komanso chilengedwe.
Kuphatikiza pa othandizira akuluakulu ofufuta, owoneka bwino amatha kugwiritsa ntchito mitundu yothandiza kuti ikwaniritse katundu kapena kumaliza zikopa. Izi zitha kuphatikizira utoto ndi utoto chifukwa cha utoto, mafuta ndi ma sexes ofewa ndi kukana madzi, komanso matenthedwe omaliza monga mawonekedwe ndi masitepe. Kusankha kwa othandizira kumatengera zomwe mukufuna kuti zikhale zachikopa, ngakhale zimakhala zotsekemera kwambiri kapena zolimba zolimba.
Kusankhidwa ndi kuphatikiza kwa zida zopangira zikopa ndi njira yovuta komanso yapadera yomwe imafunikira kumvetsetsa kwamtundu, biology, ndi sayansi yathupi. Tenneries ayenera kusamala mozama zinthu monga mtengo, mphamvu ya chilengedwe, ndi kutsatira malamulo owongolera pomwe mukuyesetsa kupanga zikopa zapamwamba kwambiri zomwe zikufuna zofuna za msika.
Monga chidziwitso chogwirizira cha nkhani zachilengedwe komanso zoyenera zimakula, palinso chidwi chopatsa chidwi chokhazikika komanso chopatsa chidwi. Mafuta ena akufufuza mankhwala ena opindika kuchokera ku magwero osinthika, monga makungwa ngati makungwa ndi zipatso, komanso matekinoloje a enzymatic monga enzymatic ndi masamba. Izi zikufuna kuchepetsa kudalira mankhwala pa mankhwala ndikuchepetsa mawonekedwe a chilengedwe.
Ponseponse, zida zopangira zikopa ndizosiyanasiyana komanso kuthira miyambo yambiri, ndikuwonetsa mbiri yabwino komanso yatsopano yokhudza makampani achikopa. Mwa kumvetsetsa ndi kuyang'anira mosamala zida zomerazi, zokopa zimatha kupitiliza kupanga zikopa zapamwamba kwambiri zomwe zimakwaniritsa zosowa za ogula pomwe akuthana ndi zovuta zokhala ndi chilengedwe.
