Kodi matumba a zida za EVA ndi chiyani?

Zida ndi zodzitetezera ndi chiyanikukonza matumba a zida za EVA? Makampani opanga zida za EVA akupita patsogolo pang'onopang'ono, ndipo kufunikira kwa matumba a zida m'mafakitale osiyanasiyana kwagawidwanso. Malinga ndi zopangidwa ndi kampani iliyonse, palinso masitayelo ambiri amatumba opangira zida. Kusiyana kwakukulu ndikuti chida chilichonse chili ndi buku komanso kapangidwe kake, ndipo chimapangidwira mafakitale apadera. Mwachilengedwe, pali kusiyana kwina kwa zida za zida zosinthidwa makonda. Ndiye zida za zida zosinthidwa ndi ziti?

Choyamba: zipangizo makonda

1. Zinthu za nayiloni

Pali zida zingapo zokhazikika zopangira zida zopangidwa mwachizolowezi, zomwe zida za nayiloni 600D, zomwe zimagwiritsidwa ntchito kwambiri m'matumba akunja, ndizogwiritsidwanso ntchito popanga zikwama zopangidwa mwamakonda. Makhalidwe ake ndi oti ndi osagwirizana ndi madontho, osavala komanso osalowa madzi, ndipo mtengo wake ndi wotsika pang'ono. Mtengo wa zinthu izi makamaka zimadalira kachulukidwe zake zakuthupi. Nayiloni zokhuthala zopanda madzi monga 1680D ndi 1800D ndizokwera mtengo kuposa 600D nayiloni. Iwo Mapangidwewo ndi ofanana ndi mawonekedwe, koma pali kusiyana kobisika pamapangidwe osungira ntchito.

2. Aluminiyamu-magnesium aloyi zakuthupi
Bokosi la zida za aluminium-magnesium alloy ndi Nokia yama foni am'manja, ndipo ndiyosiyana kwambiri ndi mafoni ena am'manja. Chofunika kwambiri cha Nokia ndi chakuti chimagonjetsedwa ndi madontho, pamene chitsulo cha aluminium-magnesium alloy ndi chakuti zonse zimakhala zolimba komanso zofewa, zosagwirizana ndi madontho, kupanikizika ndi kusinthika, komanso zimakhala zopanda fumbi, zopanda madzi komanso zopanda mafuta. Zida zamtunduwu nthawi zambiri zimagwiritsidwa ntchito m'mafakitale azachuma ndi inshuwaransi, monga ma safes, omwe amapangidwa ndi aluminium-magnesium alloy.

Kuwonjezeka kwa matumba opangira zida ndi njira yosapeŵeka ndi chitukuko cha nthawi. Mitundu yosiyanasiyana ndi masitaelo amatumba a zida zimabweretsa kumasuka kwa ogwira ntchito m'mikhalidwe yonse.
