EVA Foam Durability Analysis

Cov yam ntxwv tseem ceeb ntawm EVA Foam
EVA (ethylene-vinyl acetate copolymer) ua npuas ncauj yog cov khoom siv elastic, uas nws cov kav ntev yog nyob ntawm ntau yam. Cov khoom no muaj cov khoom zoo cushioning thiab yooj, ua rau nws tsim nyog rau kev siv xws li insoles, ntim khoom, thiab cov khoom ua si. Cov yam ntxwv tseem ceeb muaj xws li:

• Qhov ceev: Feem ntau 0.03-0.3 g / cm³
• Elastic rov qab tus nqi: Txog 80-90%
• Kev kub hauj lwm ntau yam: -40℃txog 70 degree

Qhov cuam tshuam ntawm Environmental Factors ntawm Durability
EVA ua npuas ncauj nthuav tawm qhov kev ua tau zoo sib txawv hauv qhov chaw sib txawv:

• Humidity ib puag ncig: Ntev dampness yuav ua rau cov khoom nthuav.
• UV hluav taws xob: Kev siv sab nraum zoov tuaj yeem ua rau kev laus.
• Mechanical stress: Nquag compression tuaj yeem cuam tshuam rau kev ncaj ncees.

Cov lus pom zoo rau Extending Service Life
Kev siv thiab kev saib xyuas kom zoo tuaj yeem txhim kho lub zog ntawm EVA ua npuas ncauj:

• Tsis txhob cuam tshuam rau qhov kub thiab txias.
• Ntxuav tsis tu ncua thiab ua kom qhuav.
• Xaiv qhov ceev kom tsim nyog raws li daim ntawv thov.
• Tsis txhob kov cov khoom ntse.
