Zinthu za thovu la EVA Ngati kasitomala wanu ali wokonda masewera, sipangakhale zinthu zabwinoko kuposa za EVA zomwe zimakwaniritsa zofunikira za mafani ambiri.

Ngati kasitomala wanu ndi wokonda masewera, sipangakhale zinthu zabwinoko kuposa EVA zomwe zimakwaniritsa zofuna za mafani ambiri.

Mukasamutsa zinthu kuchokera kumalo ena kupita kwina, zotayika kuchokera kugwedezeka ndi zovuta sizingapeweke.Komabe, mutha kuchepetsa izi pogwiritsa ntchito thovu la EVA losasunthika ndikubweretsa malowa kumalo anu osiyanasiyana, mateti a yoga, masiketi, zoteteza, "zida zankhondo", chisoti......

EVA, khalani ndi moyo wabwino, tetezani moyo mosamala.

EVA, ethylene-vinyl acetate, yomwe imadziwikanso kuti poly (ethylene-vinyl acetate, PEVA), ndi copolymer ya ethylene ndi vinyl acetate.Pankhani ya kusinthasintha, ili pafupi ndi elastomer, motero imadziwika kuti mphira wowonjezera, thovu la EVA, ndi mphira wa thovu.Itha kukonzedwa ngati ma thermoplastics, okhala ndi kuchuluka kwa mankhwala ophatikizika, zomwe zimapangitsa kuti pakhale ma cell otsekeka omwe amakhala ndi ma cell abwino, ofanana.

Kulemera kwa vinyl acetate nthawi zambiri kumasiyana pakati pa 18% ndi 40%, ndipo yotsalayo ndi ethylene.Kutengera zomwe zili mukupanga, magawo osiyanasiyana a kuuma kwa EVA atha kupezeka.Ndikofunikira kuganizira za kuuma kwake popeza EVA sabwereranso mawonekedwe ake atatha kukanikiza kosalekeza.Poyerekeza ndi EVA yolimba, EVA yofewa imakhala ndi kukana kwa ma abrasion pang'ono komanso moyo waufupi wa outsole, koma chitonthozo chapamwamba.

EVA thovu ili ndi zinthu zambiri zabwino:

Kukana chinyezi (kuchepa kwamadzimadzi kumayamwa)

kuthamangitsa mankhwala

Mayamwidwe amawu ndi kutsekereza mawu

Kugwedezeka ndi kugwedezeka (kugwedezeka kwamphamvu)

Kusinthasintha kwapangidwe

Kukana kwanyengo (kutsika kwa kutentha, kukana kwa radiation ya UV)

zoteteza kutentha, zosagwira kutentha

posungira

damping

Mkulu mphamvu ndi kulemera chiŵerengero

yosalala pamwamba

Plasticity, ductility, thermoplasticity, etc.

Kapangidwe kazinthu za thovu la EVA kumaphatikizapo kuphatikizika, kusakaniza ndi kuchita thovu.Utoto wa EVA umasinthidwa kukhala tizigawo ting'onoting'ono tokwanira, ndiyeno mugawo linalake, tinthu tating'onoting'ono timasakanizidwa ndi zowonjezera zina ndi mapangidwe osiyanasiyana kuti apange zinthu zosiyanasiyana za thovu la EVA. wothandizila, wotsekereza, wothira thobvu, wothira mafuta;zipangizo wothandiza ndi antistatic wothandizila, lawi retardant, kudya kuchiritsa wothandizila, colorant, etc. The anasankha thobvu zowonjezera ndi chothandizira osakaniza chimatsimikizira kachulukidwe ake, kuuma, mtundu ndi kupirira katundu.Opanga tsopano akupanga ultralight, conductive, antistatic, shock resistant, antibacterial, fireproof and biodegradable formulations pazifukwa zapadera.
