Chidule cha Zinthu za Suede
Monga chikopa chapamwamba kwambiri, suede yatchuka kwambiri m'nyumba zamakono zamagalimoto chifukwa cha kapangidwe kake kosiyana komanso magwiridwe antchito ake abwino kwambiri. Yoyambira ku France m'zaka za m'ma 1700, nsalu iyi yakhala ikukondedwa kwa nthawi yayitali chifukwa cha mawonekedwe ake ofewa, ofewa komanso okongola. Yopangidwa mwachikhalidwe kuchokera ku chikopa cha nkhosa kapena zikopa zina za nyama kudzera mu kukonza kwapadera, makampani amakono apanga suede yopangidwa mwaluso kudzera munjira zamakono zopangira nsalu, zomwe zikukulitsa njira zogwiritsira ntchito magalimoto.
M'nyumba zamagalimoto, suede ndi yabwino kwambiri ndipo imakhala yolimba komanso yotonthoza. Pamwamba pake pali ulusi wosalala wambiri, zomwe zimapangitsa kuti ikhale yofanana ndi suede yachilengedwe. Kapangidwe kameneka kamapangitsa kuti nsaluyo ikhale yolimba komanso yopepuka. Poyerekeza ndi chikopa chachikhalidwe, suede ndi yopepuka, yomwe imachepetsa kulemera kwa galimoto komanso imapangitsa kuti ikhale yomasuka. Kuphatikiza apo, mphamvu zake zosakhala ndi ziwengo zimapangitsa kuti ikhale chisankho chabwino kwa anthu omwe amasamala zachilengedwe.
Chifukwa cha kudziwika kwa chilengedwe komanso kupita patsogolo kwa ukadaulo, kugwiritsa ntchito zipangizo za suede kukupitirira kukula. Njira zamakono zopangira zimathandiza suede yopangidwa kuti isunge ubwino wake weniweni pamene ikukumana ndi miyezo yolimba yosamalira chilengedwe. Zatsopanozi sizimangoyambitsa kusintha kwa zinthuzo komanso zimapatsa opanga magalimoto kusinthasintha kwakukulu, kuwathandiza kupeza mgwirizano wabwino pakati pa zinthu zapamwamba ndi magwiridwe antchito.
Mitundu Yoyamba ya Zipangizo za Suede ndi Makhalidwe Awo
Kutengera njira zopangira ndi komwe zidachokera, zinthu za suede zitha kugawidwa m'magulu atatu: suede yachilengedwe, suede yopangidwa, ndi suede yobwezeretsedwanso. Mtundu uliwonse uli ndi mphamvu zosiyana zakuthupi ndi zamakemikolo, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito m'malo osiyanasiyana mkati mwa magalimoto.
Suede Yachilengedwe
Suede yachilengedwe imachokera ku zikopa za nyama, zomwe nthawi zambiri zimapangidwa kuchokera ku chikopa cha nkhosa, chikopa cha ng'ombe, kapena chikopa cha nswala kudzera mu njira zowunikira bwino komanso zoyeretsera. Chida ichi chimasiyanitsidwa ndi kusinthasintha kwake kwachilengedwe komanso kupuma bwino, komwe kumakhala ndi ming'alu ya 20%-30%, yokwera kwambiri kuposa zida zina. Magawo ena ndi awa:
| Chizindikiro cha Makhalidwe | Mtengo wa Parameter |
| Kulimba kwamakokedwe | 25-30 MPa |
| Mphamvu Yong'amba | 70-90 N/mm |
| Kukana Kumva Kuwawa | >50,000 ma cycle |
| Kuyamwa kwa Chinyezi | 10%-15% |
Suede yachilengedwe imadziwika ndi kapangidwe kake kapamwamba komanso tirigu wake wapadera, koma njira yopangira imagwiritsa ntchito kwambiri zinthu zachilengedwe komanso kuipitsa chilengedwe, kuphatikiza ndi ndalama zambiri. Chifukwa chake, kugwiritsa ntchito kwake m'nyumba zamakono zamagalimoto kwakhala kocheperako pang'onopang'ono.
Suede Yopangidwa
Suede yopangidwa imapangidwa pogwiritsa ntchito zipangizo za polymeric monga polyurethane (PU) kapena polyester fiber (PET). Kudzera mu njira monga spunbonding, needle-punching, kapena hydroentanglement, imapeza kapangidwe kakang'ono kofanana ndi suede yachilengedwe. Nsaluyi imakhala ndi magwiridwe antchito abwino kwambiri pomwe imapereka ndalama zambiri komanso ubwino woteteza chilengedwe. Nazi njira zake zazikulu zaukadaulo:
| Chizindikiro cha Makhalidwe | Mtengo wa Parameter |
| Kulimba kwamakokedwe | 20-25 MPa |
| Mphamvu Yong'amba | 60-80 N/mm |
| Kukana Kumva Kuwawa | > 40,000 ma cycle |
| Kuyamwa kwa Chinyezi | 8%-12% |
Suede yopangidwa ndi zinthu zachilengedwe ndi yoyenera kwambiri malo omwe amafunika kukana kukwawa kwambiri, monga zophimba chiwongolero ndi zotetezera mipando. Kupanga kwake sikubweretsa mpweya woipa komanso kuonetsetsa kuti zinthuzo ndi zabwino nthawi zonse.
Suede Yobwezerezedwanso
Suede yobwezerezedwanso ndi chinthu chatsopano chomwe chimateteza chilengedwe chomwe chimapangidwa kuchokera ku zinyalala za nsalu zobwezerezedwanso kapena mabotolo apulasitiki otayidwa. Kudzera muukadaulo wapamwamba wobwezeretsanso mankhwala komanso njira zobwezeretsanso ulusi, chinthuchi chimagwiritsa ntchito bwino kwambiri zinthu. Makhalidwe ake ndi awa:
| Chizindikiro cha Makhalidwe | Mtengo wa Parameter |
| Kulimba kwamakokedwe | 18-22 MPa |
| Mphamvu Yong'amba | 50-70 N/mm |
| Kukana Kumva Kuwawa | > 30,000 ma cycle |
| Kuyamwa kwa Chinyezi | 6%-10% |
Suede yobwezerezedwanso sikuti imangokhala ndi makhalidwe abwino kwambiri komanso imakwaniritsa zofunikira za makampani amakono a magalimoto kuti chitukuko chikhale chokhazikika. Kupanga kwake kumachepetsa mpweya woipa wa carbon ndi pafupifupi 50% poyerekeza ndi zipangizo zachikhalidwe ndipo kumachepetsa kwambiri mtengo wa zinthu zopangira.
Mitundu itatu iyi ya zinthu zopangidwa ndi suede imapereka mawonekedwe osiyana, kupatsa opanga magalimoto njira zosiyanasiyana zosankhidwira. Mu ntchito zenizeni, mitundu yoyenera ya zinthu imatha kusankhidwa kutengera zofunikira pakugwira ntchito komanso mtengo wa zinthu zosiyanasiyana zamagalimoto.
Kugwiritsa Ntchito Zipangizo za Suede mu Magalimoto Amkati
Kugwiritsa ntchito zipangizo za suede m'magalimoto amakono kwasintha kwambiri, kupitirira mipando yachikhalidwe mpaka kuzinthu zatsopano zogwirira ntchito, kusonyeza kuthekera kwake kogwiritsidwa ntchito kwambiri. Maphunziro otsatirawa akufufuza momwe zinthu zosiyanasiyana za suede zimagwiritsidwira ntchito m'magalimoto osiyanasiyana.
1. Malo Osungira Mpando ndi Zotsamira Mutu
2. Kukulunga ndi Kukongoletsa Chiwongolero cha Chiwongolero
3. Mawonekedwe a Headliner Lining ndi Pakhomo
Ntchito zothandizazi zikuwonetsa bwino momwe zinthu za suede zimagwirira ntchito popanga mkati mwa magalimoto amakono, komanso ubwino wapadera wa mitundu yosiyanasiyana ya zinthu m'mikhalidwe inayake.
Zatsopano Zaukadaulo ndi Ziyembekezo Zachitukuko cha Zipangizo za Suede
M'zaka zaposachedwapa, kupita patsogolo kwakukulu kwa ukadaulo kwachitika pakupanga zinthu za suede mkati mwa magalimoto, zomwe zawonetsa kuthekera kwakukulu makamaka mu nanotechnology, chitukuko cha zinthu zanzeru, komanso kukonza njira zotetezera chilengedwe. Kupita patsogolo kumeneku sikuti kwangowonjezera mphamvu zoyambira za zinthuzo komanso kwakhazikitsa maziko olimba a momwe zidzagwiritsidwire ntchito mtsogolo.Kuti mudziwe zambiri, musazengereze kulankhulana nafementhawi iliyonse.
