Mitundu yoyambira ya ng'oma wamba Ng'oma ndiye chida chofunikira kwambiri pakupanga ziwiya zofufutira, ndipo chitha kugwiritsidwa ntchito ponyowa pakuwotcha. Itha kugwiritsidwanso ntchito pazinthu zachikopa zofewa monga chikopa chapamwamba cha nsapato, chikopa cha zovala, chikopa cha sofa, chikopa cha glove, ndi zina zotero, chikopa chofewa komanso chowunjika cha suede, kubwezeretsa chinyezi komanso kunyowa kwachikopa chowuma, komanso kugudubuza kwaubweya.
The ng'omaimapangidwa makamaka ndi chimango, ng'oma ndi chipangizo chake chotumizira, Thupi la ng'oma ndi matabwa kapena zitsulo zozungulira zitsulo zomwe zitseko za 1-2 zimatsegulidwa. Pa ntchito, ikani khungu ndi madzimadzi opareshoni pamodzi mu ng'oma ndi kuzungulira kusonkhezera ndi kuchititsa khungu kupinda pang'onopang'ono ndi kutambasula, kuti kufulumizitsa ndondomeko anachita ndi kusintha mankhwala khalidwe ndi cholinga.
Miyeso yayikulu ya thupi la ng'oma ndi mainchesi amkati D ndi kutalika kwamkati L. Kukula ndi kuchuluka kwake kumakhudzana ndi kugwiritsa ntchito, batch yopanga,ndondomeko njira, etc. Malingana ndi njira zosiyanasiyana zokometsera zonyowa, ng'oma zazinthu zosiyanasiyana zatsirizidwa ndi kupangidwa kuti zigwirizane ndi zosowa za ndondomeko zosiyanasiyana.
Ng'oma yomiza ndi yoyenera kuchitapo ntchito zofufutira zisanakhale monga kumizidwa, kutaya madzi m'thupi, ndi kukulitsa laimu. Pamafunika zolimbitsa mawotchi kanthu ndi lalikulu voliyumu. Nthawi zambiri, chiŵerengero cha m'mimba mwake D mpaka utali wamkati L ndi D/L=1-1.2. Kutalika kwa ng'oma yomwe imagwiritsidwa ntchito kwambiri ndi 2.5-4.5m, kutalika kwake ndi 2.5-4.2m, ndipo liwiro ndi 2-6r / min. Pamene m'mimba mwake wa ng'oma ndi 4.5m ndi kutalika ndi 4.2m, pazipita Kutsegula mphamvu akhoza kufika 30t. Imatha kunyamula zikopa za ng'ombe zokwana 300-500 panthawi yomwe imagwiritsidwa ntchito kumizidwa m'madzi ndi kukulitsa kwa depilation.
Kukula kwake komanso liwiro la ng'oma yowotchera masamba ndizofanana ndi ng'oma yomiza. Kusiyana kwake ndikuti shaft yolimba imagwiritsidwa ntchito kuonjezera katundu. Mlingo wogwiritsa ntchito voliyumu ukhoza kufika kuposa 65%. Ndikoyenera kuyika ma baffles achidule okhala ndi mphamvu zambiri ndikutengera utsi wodziwikiratu. Valavu imachotsa mpweya wopangidwa panthawi yowotcha masamba, ndipo imakhala ndi nthawi yopita patsogolo ndi zida zosinthira kuti zithetse vuto la kukulunga pakhungu. Ziwalo zachitsulo za m'ng'oma zimafunika kuzikuta ndi mkuwa kuti zowotchera masamba zisaonongeke komanso kuti zizikhala zakuda zikakhudzana ndi chitsulo, zomwe zingasokoneze chikopa chamasamba.
Ng'oma yowotcha ya chrome ndi yoyenera kukonzedwa konyowa monga kupukuta, kufewetsa, pickling pofufuta, utoto ndi kuwonjezera mafuta, ndi zina zotero. Chiŵerengero cha m'mimba mwake wa ng'oma ndi kutalika kwa mkati D/L = 1.2-2.0, ndipo m'mimba mwake wa ng'oma yomwe imagwiritsidwa ntchito kawirikawiri ndi 2.2- 3.5m, kutalika kwa 1.6-2.5m, mitengo yamatabwa imayikidwa pakhoma lamkati la ng'oma, ndi liwiro lozungulira la ng'oma ndi 9-14r / min, yomwe imatsimikiziridwa molingana ndi kukula kwa ng'oma. Katundu wa ng'oma yofewa ndi yaying'ono, liwiro ndi lalitali (n = 19r / min), chiŵerengero cha mkati mwa ng'oma mpaka kutalika kwa mkati ndi pafupifupi 1.8, ndipo zochita zamakina zimakhala zamphamvu.
M'zaka makumi angapo zapitazi, ndi zofunikira za chitetezo cha chilengedwe ndi zofunikira za njira zatsopano zogwirira ntchito ndikumaliza, mapangidwe a ng'oma wamba akhala akuwongolera mosalekeza. Limbikitsani kufalikira kwa madzi ogwiritsira ntchito mu ng'oma, ndikutulutsa madzi otayira m'njira yolunjika, yomwe imapindulitsa pa chithandizo chamankhwala; gwiritsani ntchito zida zodziwira ndi makina otenthetsera kuti muwongolere bwino magawo azinthu ndikuwongolera mtundu wazinthu; gwiritsani ntchito makompyuta pakuwongolera pulogalamu, kudyetsa basi, kutsitsa ndi kutsitsa mwamakina, kugwiritsa ntchito bwino ndikuchepetsa mphamvu yantchito,kutsika kwa zinthu zakuthupi,kuwononga pang'ono.
