Amapanga mmalo khungu: mbamuikha chikopa, vinilu, ekokozha

Kupanga khungu yokumba adanyamuka chosowa zipangizo apamwamba zachilengedwe ndi mtengo awo okwezeka. zipangizo yokumba (vinilu, kuumbidwa khungu ekokozha etc.) ndi zimakhalanso zotsika mtengo. Monga luso bwino chitukuko cha akale ndi atsopano. makampani lero umabala mitundu yosiyanasiyana angapange, amene ntchito kusoka mapepala, nsapato, zovala, katundu wachikopa.

Shoe msika posachedwapa anasefukira ndi nsapato zimakhalanso zotsika mtengo zimene zimawoneka osiyana chikopa. Shopu othandizira kunena kuti masoka mbamuikha chikopa. Koma mtundu wa zinthu si achilengedwe, koma zopangidwa, zosavuta kupanga khungu lake ntchito zinyalala. Motero, nkhaniyi sitinganene kuti. kupanga ndondomeko ya chuma yokha tichipeza comminution wa feedstock (zatsalira khungu kudulira zipangizo extruded ndi fumbi chikopa) ndi kusakaniza ndi resins, binders ulusi. Ku misa analandira aumbike mwa chinsalu mosabisa, amene zouma ndi wothinikizidwa. Gawo lotsiriza la kupanga zinthu "yaying'ono khungu" ndi ntchito topcoat wosanjikiza. Ngakhale ambiri masitepe kupanga, mtengo wa zinthu zachepa, imbaenda kutchuka kwake ndi opanga nsapato wotsika ndi zovala.

A bwino zopangidwa mbamuikha chikopa pafupifupi osiyana zachilengedwe ndi kununkhira zambiri ali ofanana (ngati apamwamba utomoni ntchito). kusiyana ndi anamvera pamene ankavala. Kale mu mwezi woyamba wa opareshoni ya nsapato, zovala kapena thumba anapanga nkhaniyi okutidwa ndi ming'alu ing'onoing'ono, ndipo patapita kuoneka creases, ndi chiswa mankhwala mu khola. Vuto lomwelo ali nsapato anapanga chikopa yokumba. Ena opanga zovala apeza kukondera njira - kupanga nsapato ndi pamodzi. M'madera amene si poyera kuti avale katundu aikidwa mbamuikha chikopa, ena - zachilengedwe. Choncho yafupika mtengo pang'ono ndipo si khalidwe limawonongekeratu.

Wina zosinthika zipangizo yokumba - ekokozha. chitukuko anali anayambitsa ku Ulaya chifukwa cha zinthu mkulu wa Anthu nyama ufulu, amene boycotted ntchito zipangizo zachilengedwe chiyambi nyama, kuchititsa zomvetsa zikuluzikulu mabizinezi. Izi zinachititsa kuti chitukuko cha chuma mpweya permeable zomwe si kulenga zotsatira kutentha ndipo ali mkulu durability. Ndi maonekedwe ake ndi ntchito ekokozha chimaposa ngakhale ena Anzawo achilengedwe. Nkhanizi ndi zofewa ndi kutentha ndi kuzizira, nthawi okoma ndi wofewa kwambiri. Iwo bwino ntchito makampani mipando, kusoka zovala ndi nsapato komanso zikwama zam'manja ndi katundu wachikopa mankhwala.

Pali zinthu monga chikopa vinilu. Monga maziko kupanga ake angagwiritsidwe ntchito zachilengedwe ndi kupanga ulusi onse. Kuchokera pa zimene tikuphunzira zinthu zimadalira makhalidwe monga stretchability, mphamvu, luso amaika, etc. Pamaziko a anasankha nyimbo zosiyanasiyana ntchito, kenako ndondomeko kuwamaliza. Mu stepi ino akhoza kugwiritsa ntchito zosiyanasiyana njira: embossing, akupera, kapena kutsatira makalipeti lacquer wosanjikiza myate, kudziyerekeza, etc. Chifukwa ndi zinthu zimene simulates osati losiyanasiyana chikopa kapena suwedi, komanso osiyanasiyana yokhotakhota nsalu. Chiwerengero cha mithunzi ndi mitundu amadziwa Palibe malire. Inu mukhoza kutenga zachitsulo mtundu, ndi bilimankhwe ndi mafunde osiyana ndi tints.

Opanga amanena kuti zipangizo apamwamba ndi ntchito zabwino, ndipo ngakhale mbamuikha chikopa ukhoza nthawi yaitali ngati anapanga zida zabwino kugwilizana ndi subtleties onse sayansi. Koma mmene kudziwa kumene mankhwala apamwamba, ndipo kunalibe? Wina njira - kukhulupirira kokha zopangidwa okhazikika bwino ndipo makampani, amene sadzalola ntchito zipangizo otsika-quality, kapena kugula kutsimikiziridwa khungu zachilengedwe.
