3. Matumba a chikopa omwe ali ndi khalidwe labwino samangokhala ndi machitidwe osagwirizana, komanso amakhala ndi machitidwe osakanikirana.Pali timagulu tating'ono tambiri, koma timagawidwa mosiyanasiyana.Ngati ndi thumba lachikopa labodza, simungathe kuwona mawonekedwe otere, ngakhale atakhalapo!
4. Thumba lachikopa lili ndi mawonekedwe osiyana.Zikuwoneka zokongola kwambiri.Chithandizo cha singano ndi ulusi uliwonse ndizokhazikika, ndipo zimakongoletsedwa molingana ndi njere.Ngati ndi zabodza, palibe mapangidwe oterowo, ndipo m'mphepete ndi ngodya zidzawonetsa ma burrs!
5. Kulemera kwa matumba achikopa ndi mfundo yofunika kwambiri pamene akugawidwa.Ngati zili zenizeni, matumbawa mwachiwonekere ndi olemera kwambiri, chifukwa khalidwe la ubweya ndi lolemera.Ngati ndi yabodza, ndiyopepuka, chifukwa yonse ndi yachikopa.

7. Thumba lachikopa ndi lotanuka kwambiri.Mukachifinya, chidzachira msanga komanso mwachibadwa.Ngati chinyengocho chapangidwa, mwachiwonekere sichikhala ndi elasticity kapena kumverera kovuta kwambiri.Akafinyidwa, zimakhala zovuta kuchira.Muyeneranso kulabadira izi.
1, Kusankha zinthu zoyenera ndiye maziko a thumba.Pali mitundu yambiri ya nsalu, monga nsalu, zikopa zopangira, PU ndi zikopa.Inde, chikopa ndi chabwino kwambiri.Kwa chikopa cha PU, chikopa chopyapyala chimakutidwa ndi PU, chomwe chimamveka bwino komanso chonyezimira.Mukhozanso kuchitira ena chitsanzo mankhwala pa chikopa pamwamba.Mzerewu umapangidwa kwambiri ndi ulusi wamankhwala komanso chinsalu.Chofunika kwambiri si kukhala wofewa kwambiri.Ngati ili yofewa kwambiri, padzakhala zopinga poyika zinthu.Potulutsa zinthu kunja, mzerewo umatulutsidwanso.Mukatsegula chikwamacho, nthawi zonse mumakhala mulu wazitsulo zosakhazikika, ndipo simungathe kuwona zinthu zina m'thumba.Chikwamacho chikatsegulidwa, chinsalucho chiyenera kukhala pafupi ndi nsalu, ndipo malo amkati ayenera kukhala omveka bwino, omwe amafanana ndi kukula kwa thumba, ndipo mgwirizano ndi wabwino.Zindikirani chikopa: chikopa ndi chikopa chochita kupanga ndi mayina odziwika a chikopa chachilengedwe kusiyanitsa chikopa chopangidwa.Ndizofala kwambiri pamsika wazinthu zachikopa.Dermis imapangidwa makamaka ndi kotekisi yanyama.Pali mitundu yambiri ya matumba a akazi apamwamba, kuphatikizapo chikopa cha ng'ombe, chikopa cha nkhosa, chikopa cha nkhumba, ndi zina zotero.Choncho, chikopa si dzina lachikopa lachilengedwe chonse, komanso chizindikiro chodziwika bwino pamsika wamalonda.Chifukwa chikopa chimakhala ndi timitolo tating'ono ta ulusi, chimakhala ndi mphamvu komanso mpweya wabwino.Khungu lililonse la nyama lili ndi tsitsi, epidermis ndi dermis.Epidermis ili pansi pa tsitsi komanso pafupi ndi pamwamba pa dermis, ndipo imapangidwa ndi maselo a khungu la maonekedwe osiyanasiyana.Makulidwe a epidermis amasiyana ndi nyama zosiyanasiyana, mwachitsanzo, makulidwe a khungu la ng'ombe ndi 0.4 ~ 1.7% ya makulidwe onse;1.8-3.5% pakhungu la nkhosa ndi mbuzi;Khungu la nkhumba ndi 2.5 ~ 5.5%.Dermis ili pansi pa epidermis, pakati pa epidermis ndi subcutaneous minofu, ndipo ndi gawo lalikulu la khungu laiwisi.Kulemera kwake kapena makulidwe ake amawerengera zoposa 85% ya zikopa zosaphika.Zikopa zambiri za nyama zimatha kugwiritsidwa ntchito kupanga zikopa.Chachiwiri, tikhoza kuona kuti maonekedwe a chikopa alibe maziko, zipangizo zopangira zimakhala ndi maziko, zikopa zimakhala ndi ma pores ang'onoang'ono, ndipo chikopa chotsanzira chilibe maziko.Mukakhudzanso, pulasitiki ya zipangizo zopangira ndi yamphamvu kwambiri komanso yonyezimira.Zimamva kuzizira mukachigwira m’nyengo yozizira, ndipo chikopacho chimakhala chosalala mukachigwira.Kununkhira kwachikopa kwamafuta anyama (ndiko kuti, kununkhira kwachikopa), komanso kununkhira kwachikopa chapulasitiki., Mukakanikiza gawo lofewa la chinthu chomalizidwa ndi chala chachikulu, pamakhala timitu tating'ono ting'onoting'ono tating'onoting'ono tozungulira chala chachikulu. .Pamene chala chachikulu chikukwezedwa, chitsanzocho chimasowa, chomwe ndi dermis.Komabe, zinthu zopangazo sizingakhale zopanda chitsanzo, kapena pangakhale mitundu yolimba.Pamene chala chachikulu chikukwezedwa, chitsanzocho sichikutha, kusonyeza kuti nsanje yambewu pamwamba pa zinthu ndi mesh wosanjikiza pansipa wasiyanitsidwa.Yang'anani gawo la mtanda.Chigawo cha dermal cross chimapangidwa ndi ulusi wosakhazikika.Pambuyo pochotsa ulusi wosweka wa khungu ndi zikhadabo, gawo la mtanda lilibe kusintha koonekeratu.Kwa dermis, mawonekedwe a ziwalo zosiyanasiyana ndi osasinthasintha, ndipo fungo la fungo ndi nsomba, pamene fungo la chikopa chochita kupanga ndi pulasitiki kapena mphira, ndipo mawonekedwe a gawo lililonse ndi ofanana.Chikopa chophimbidwa ndi filimu chimatanthawuza chikopa chopangidwa ndi chikopa chachilengedwe chamkati monga maziko, m'malo motchedwa "chikopa", chomwe chimayikidwa ndi wosanjikiza pamwamba pa nyama yotayirira pansi pa chikopa chachilengedwe.Ikani madontho ang'onoang'ono amadzi pakhungu, ndipo patapita mphindi zingapo, madontho amadzi amafalikira kudzera mu pores, ndipo madontho onyowa owoneka bwino amatha kuoneka kuti amamwa madzi.Pali fungo la tsitsi loyaka pamakona a chikopa, pamene chikopa chotsanzira chimanunkhiza pulasitiki.Chikopa ndi chakuda, chowala komanso chofewa, pamene chikopa chotsanzira chimakhala chowala.
