Ethylene-vinyl acetate copolymer CAS 24937-78-8 (EVA) ili ndi ntchito zosiyanasiyana, zotsatirazi ndi madera ake akuluakulu:
Munda wamafilimu wowonda
Filimu yaulimi: EVA ili ndi kufalitsa kwabwino kwa kuwala, kuteteza kutentha komanso kukana nyengo, ndipo nthawi zambiri imagwiritsidwa ntchito popanga filimu yaulimi. Ikhoza kukhalabe ndi kutentha ndi chinyezi mu wowonjezera kutentha, kulimbikitsa kukula kwa mbewu, ndi kuwonjezera moyo wautumiki wa filimuyo.
Filimu yonyamula: Kanema wa EVA ali ndi kusinthasintha kwabwino, kuwonetsetsa komanso kukana kuphulika, koyenera kulongedza zinthu zosiyanasiyana, monga chakudya, zofunikira zatsiku ndi tsiku, ndi zina zambiri. Itha kupereka ntchito yabwino yoteteza pomwe ikuwonetsa mawonekedwe azinthu.
Munda wazinthu za nsapato
Sole: EVA ili ndi mawonekedwe a kufewa, kusalala bwino, kulemera pang'ono, kukana kuvala, etc., ndiye chinthu choyenera kupanga chokha. Chokhacho chopangidwa ndi EVA ndichosavuta kuvala, chimakhala ndi mayamwidwe abwino, ndipo chingachepetse kutopa kwa phazi.
Pamwamba: EVA ingagwiritsidwenso ntchito kupanga zipangizo zapamwamba, kupereka kukhudza kofewa komanso kupuma bwino, kupanga nsapato kukhala yabwino komanso yokongola.
Hot Sungunulani zomatira munda
EVA yotentha yosungunula zomatira: ili ndi ubwino wa kukhuthala kwamphamvu, kuchiritsa mwachangu, kukana kutentha pang'ono, ndi zina zotero, zomwe zimagwiritsidwa ntchito kwambiri popanga, kumanga, kupanga mipando ndi mafakitale ena. Itha kugwiritsidwa ntchito kumangiriza mapepala, matabwa, pulasitiki ndi zinthu zina, zosavuta kugwiritsa ntchito, zitha kupititsa patsogolo kupanga.
Waya ndi chingwe munda
Insulation wosanjikiza: EVA ali ndi ntchito yabwino kutchinjiriza, kukana madzi ndi kukana dzimbiri mankhwala, angagwiritsidwe ntchito ngati insulating wosanjikiza zakuthupi waya ndi chingwe, angathe kuteteza waya ndi chingwe ku chikoka cha chilengedwe chakunja, kuonetsetsa chitetezo ndi kudalirika kwa kufala mphamvu.
Sheath: EVA itha kugwiritsidwanso ntchito kupanga sheath ya waya ndi chingwe, kupereka chitetezo chamakina ndi ntchito yoletsa kukalamba, kukulitsa moyo wautumiki wa waya ndi chingwe.
Minda ina
Zoseweretsa: EVA ndi yofewa, yopanda poizoni, yopanda fungo ndi mikhalidwe ina, yomwe nthawi zambiri imagwiritsidwa ntchito popanga zoseweretsa, monga zoseweretsa za ana, ma puzzles, ndi zina zotero, kuonetsetsa chitetezo ndi chitonthozo cha kugwiritsidwa ntchito kwa ana.
Katundu wamasewera: Amagwiritsidwanso ntchito kwambiri pazinthu zamasewera, monga masewera a MATS, yoga MATS, ndi zina zambiri, zomwe kufewa kwake komanso kukhazikika kungapereke chithandizo chabwino komanso kutsitsa.
Zopangira thovu: thovu la EVA lili ndi kulemera kopepuka, kofewa, kuteteza kutentha, kutsekereza mawu ndi zinthu zina, zitha kugwiritsidwa ntchito kupanga zinthu zosiyanasiyana za thovu.
