Nyumba za EVA (ethylene vinyl acetate) zikuchulukirachulukirachulukirachulukirachulukira chifukwa cha zomwe zili zopanda madzi komanso zolimba. Milandu imeneyi imagwiritsidwa ntchito kwambiri kuteteza zida zamagetsi, makamera, ndi zinthu zina zosalimba kumadzi, fumbi, ndi kukhudzidwa. Njira yopangira milandu yopanda madzi komanso yolimba ya EVA imaphatikizapo njira zingapo zowonetsetsa kuti chomaliza chikukwaniritsa miyezo yapamwamba kwambiri. M'nkhaniyi, tiwona momwe angapangire amadzi komanso amphamvu EVA mlandu, kuchokera pakusankha zinthu mpaka kuunika komaliza kwa zinthu.
Kusankha zinthu
Kupanga kwamilandu yopanda madzi komanso yolimba yachitetezo cha EVA kumayamba ndikusankha mosamala zida zapamwamba za EVA. EVA ndi copolymer ya ethylene ndi vinyl acetate, kupanga cholimba, chosinthika, komanso chosalowa madzi. Kusankha zinthu kumaphatikizapo kusankha kalasi yoyenera ya EVA kuti ikwaniritse zofunikira za mpanda wopanda madzi komanso wolimba. Zinthu za EVA ziyenera kukhala ndi kuuma koyenera komanso kusinthasintha kuti zipereke chitetezo chokwanira pazomwe zilimo.
Kuumba
Zinthu za EVA zikasankhidwa, sitepe yotsatira pakupanga ndi kuumba. Zinthu za EVA zimatenthedwa ndikubayidwa mu nkhungu kuti zipange wotchiyo momwe mukufunira komanso kukula kwake. Chikombolecho chimapangidwa mosamala kuti chitsimikizire kuti chikugwirizana ndi chipangizo chamagetsi kapena zinthu zina zomwe zili m'bokosi. Kapangidwe kake ndi kofunikira kuti mukwaniritse zomwe chipolopolo cha EVA sichikhala ndi madzi komanso cholimba, chifukwa chimatsimikizira kapangidwe kake ndi kukhulupirika kwa chinthu chomaliza.
Kusindikiza ndi kugwirizana
Mukapanga zinthu za EVA kukhala mawonekedwe omwe mukufuna, gawo lotsatira ndikusindikiza ndi kumata. Nyumba zopanda madzi za EVA zimafuna chisindikizo chopanda mpweya kuti madzi ndi fumbi zisalowe m'nyumbamo. Gwiritsani ntchito njira zaukadaulo zosindikizira monga kuwotcherera pafupipafupi kapena kusindikiza kutentha kuti mupange zolumikizira zosalowa madzi. Kuphatikiza apo, njira zomangira zimagwiritsidwa ntchito kukulitsa kukhulupirika kwamilandu, kuwonetsetsa kuti imatha kupirira zovuta komanso kusagwira bwino ntchito.
Kuwonjezera ndi padding
Kuti mulimbikitse kulimba kwa chipolopolo cha EVA, zida zolimbikitsira ndi zodzaza zimawonjezeredwa panthawi yopanga. Zida zolimbikitsira monga nayiloni kapena fiberglass zimaphatikizidwa mu kapangidwe ka EVA kuti apereke mphamvu zowonjezera komanso kuuma. Zipangizo zomangira monga thovu kapena velvet zimagwiritsiridwanso ntchito kubisa ndi kuteteza zinthu zomwe zatsekeredwa kuti zisagwe ndi kukwapula. Kuphatikizika kwa kulimbikitsa ndi padding kumatsimikizira kuti mlandu wa EVA umapereka chitetezo chokwanira ndikusunga mawonekedwe ake opepuka komanso onyamula.
Kuyesa ndi Kuwongolera Ubwino
Ntchito yopanga ikamalizidwa, chipolopolo chopanda madzi komanso cholimba cha EVA chidzayesedwa mozama ndikuwongolera khalidwe. Mayesero osiyanasiyana, kuphatikiza kuyezetsa kumizidwa m'madzi, kuyesa kwamphamvu, ndi kuyesa kulimba, amachitidwa kuti awonetsetse kuti mlanduwo ukukwaniritsa miyezo yotetezedwa ndi madzi komanso yolimba. Kuyang'ana kwaubwino kumachitidwa kuti muwone ngati pali zolakwika kapena zolakwika m'mabokosi, kuwonetsetsa kuti malonda apamwamba okha ndi omwe amatulutsidwa pamsika.
kuyendera komaliza kwa mankhwala
Gawo lomaliza pakupanga ndikuwunika bokosi la EVA lomalizidwa. Bokosi lililonse limawunikidwa mosamala ngati pali zolakwika zilizonse zopanga, monga zosokera zosagwirizana, zolumikizira zofooka, kapena kutsekereza madzi osakwanira. Njira yowunikirayi imaphatikizansopo kuyang'ana kukongola ndi magwiridwe antchito a mabokosiwo kuti atsimikizire kuti akukwaniritsa zofunikira pakuletsa madzi komanso kulimba. Milandu iliyonse yolakwika idzazindikirika ndikuwongolera musananyamulidwe ndikutumizidwa kwa kasitomala.
Mwachidule, kupanga milandu yopanda madzi komanso yolimba ya EVA kumaphatikizapo njira yosamala yomwe imaphatikizapo kusankha zinthu, kuumba, kusindikiza ndi gluing, kulimbikitsa ndi kudzaza, kuyesa ndi kulamulira khalidwe, ndi kuyang'anitsitsa komaliza kwa mankhwala. Potsatira mfundo zokhwima komanso kugwiritsa ntchito ukadaulo wapamwamba wopanga, opanga amatha kuwonetsetsa kuti milandu ya EVA ili ndi chitetezo chokwanira komanso cholimba, zomwe zimapereka chitetezo chodalirika pazinthu zamtengo wapatali m'malo osiyanasiyana. Pomwe kufunikira kwa ogula kukhazikika, njira zosungiramo madzi zikupitilira kukula, kupanga mabokosi apamwamba a EVA kumakhalabe kofunikira kuti akwaniritse izi.
