Nws tuaj yeem hais tias cov ntaub ntawv EVA tseem nrov heev nyob rau xyoo pua 21st. EVA cov ntaub ntawv yog dav siv nyob rau hauv ntau yam kev lag luam hluav taws xob thiab lwm yam kev lag luam. Tam sim no qhov kev thov rau EVA cov ntaub ntawv yuav nce ntxiv rau yav tom ntej.
1. Cov khoom siv hluav taws xob zoo heev ntawm EVA: foaming ces kaum feem ntau yog siv ntawm 80t, foaming Px ntsuas tuaj yeem tiv taus 70-80 degree, thiab foaming PP tuaj yeem tiv taus 120t. Foaming PP hauv
Tawm ntawm 120 degrees Celsius rau 21 teev. Qhov loj me me shrinkage tsawg dua 2 feem pua, thiab cov npuas PE shrinks li ntawm 40 feem pua nyob rau theem mob. Yog li ntawd, foaming PP tuaj yeem siv rau kev siv kub * 100t zaus.
2. Cov khoom siv EVA nrog cov khoom siv zoo heev: Siv Ace hom EVA ua npuas ncauj khoom ntawm Koha Electric Company ntawm Nyiv ua piv txwv. Nws mechanical zog xws li tensile zog thiab tearing zog
Qib siab ntawm foamed plastics; Nws lub zog compression ** nruj PUR thiab ua npuas ncauj Ps. Piv nrog cov mos mos PUR, Dong muaj qhov nruab nrab compression zog;
3. EVA cov ntaub ntawv tseem ceeb rwb thaiv tsev: foamed PP thiab foamed PE - zoo li yog ib tug kaw npuas qauv, yog li ntawd, nws thermal conductivity yuav tsis cuam tshuam los ntawm cov khoom ya raws, vim hais tias nws thermal conductivity yog qis dua foamed PE, muaj qhov tseem ceeb rwb thaiv tsev, yog li nws muaj peev xwm. siv los ua cov khoom siv rwb thaiv tsev zoo tshaj plaws.
4. Cov khoom siv EVA nrog cov resilience muaj qhov cuam tshuam rau lub zog nqus.
5. Cov tshuaj tiv thaiv corrosion ntawm EVA cov ntaub ntawv zoo dua li lwm cov khoom ua npuas ncauj; Cov roj resistant kom tau raws li qhov xav tau ntawm lub tes tsho greasy ntim zaub mov.
6. Cov khoom siv EVA muaj kev ntxhov siab zoo tawg ua haujlwm.
7. EVA khoom ua npuas ncauj PP piv nrog npuas PS, combustion yam tsis muaj roj tso tawm.
8. Cov khoom siv EVA kuj tuaj yeem siv dua.
