Cov yam ntxwv lub cev ntawm Eva

Lub cev kev ua tau zoo ntawm Eva (Ethylene-Vinyl acetate Copolymer) feem ntau suav nrog lub zog hauv qab no: Hardness, rhuav lub teeb, thiab elasticity. Txhua qhov ntsuas tau nws txoj kev ntsuas thiab cov xwm txheej thov tawm, kom ntxaws raws li hauv qab no:

1. Hardness:
Hardness yog hais txog cov khoom siv tiv thaiv kom deformation, piv txwv li, qhov muag muag lossis hardness lossis hardness lossis hardness lossis nyuaj ntawm cov khoom, feem ntau ntsuas siv DETORTE DUR SIT SIT SIT SITILT. Lub hardness ntau ntawm cov ntaub ntawv ua npuas ncauj ntawm EVA yog qhov dav heev, txij li ntau dua 10 degrees rau ntau tshaj 80 degrees. Qhov ntsuas no yog qhov tshwj xeeb tshaj yog rau kev siv xws li insoles thiab cushioning cov ntaub ntawv. Txawv nyuaj qib ntawm cov khoom EVA yog qhov haum rau kev siv sib txawv. Piv txwv li, khau soles feem ntau yuav tsum muaj kev nyuaj siab ntau dua, thaum cov ntaub ntawv sab hauv yuav xav tau qhov nyuaj qis dua los txhim kho.

2. Cov ntiajteb txawj nqus tshwj xeeb:
Cov kev nqus tshwj xeeb, tseem hu ua tuab, yog qhov sib piv ntawm cov khoom siv loj rau nws ntim. Thaum coob tus neeg tuaj yeem ua qhov ntsuas kev ua haujlwm uas siv cov cuab yeej yooj yim, hauv ib qho chaw tshaj lij, lub microcomputer ceev sib npaug yog feem ntau siv rau kev ntsuas raug. Cov kev nqus tshwj xeeb yog qhov tseem ceeb hauv kev ntsuas lub teeb pom kev zoo thiab lub zog ntawm cov khoom siv, qhov tseem ceeb rau cov khoom lag luam xws li kev pom kev thiab lub zog.

3. Elongation:
Elongation yog hais txog kev elongation thaum tawg. Thaum kuaj, cov khoom siv ua npuas ncauj xa mus rau qhov loj me (piv txwv li, 60 * 10 * 5 hli), thiab tom qab ntawd lub tshuab kuaj sim ua kom ncab nws ntawm qhov nrawm. Qhov ntev ntawm so faib los ntawm thawj qhov ntev yog elongation. Elongation tau qhia txog kev tawv thiab qhov tsis zoo ntawm cov khoom siv; Ib qho siab dua elongation txhais tau tias cov khoom tuaj yeem ncav tau ntev dua ua ntej ua txhaum.

4. Tensile lub zog:
Lub zog tensile yog qhov siab tshaj plaws load cov khoom tuaj yeem tiv taus thaum nws tawg, feem ntau sim ua ib txhij nrog elongation. Nws yog qhov ntsuas ntawm cov khoom siv tiv thaiv mus rau lub zog tensile. Lub zog siab tshaj plaws qhia tau tias cov khoom siv tsis yooj yim thaum siv thaum siv lub zog siab tensile muaj zog, xws li ib puag ncig ntawm cov khau ua si.

5. Muab lub zog:
Kua muag lub zog yog cov khoom siv tiv thaiv los rhuav. Cov qauv xeem cuam tshuam nrog txiav cov ntawv me me, txhim kho ob sab ntawm cov neeg hauv lub tshuab kuaj Tensile, thiab tom qab ntawd rub. Lub thauj khoom tau nyiaj dhau yog cov kua muag. Lub zog siab ua lub zog siab txhais tau tias cov khoom yuav tsawg dua los rhuav tshem, uas yog qhov tseem ceeb rau cov ntaub ntawv muaj zog, xws li cov ntaub ntawv tiv thaiv thiab cov khoom ntim.

6. Kev teeb tsa teeb tsa:
Teeb tsa compression teeb tsa (qee zaum tsuas yog xa mus rau compression lossis compression deformation) yog qib ntawm kev ntxhov siab hauv qab kev ntxhov siab. Qhov kev xeem cuam tshuam nrog kev ua tiav ntawm kev ua tiav, muab lawv tso rau hauv cov cuab yeej tseem ceeb, thiab tom qab ntawd muab tso rau hauv cov laus tshuab rau ob peb teev. Thaum kawg, lub disc tuab yog ntsuas, thiab tus nqi tau suav los ntawm ntau coefficients. Kev txo cov kev siv tau teeb tsa tau qhia tias cov khoom siv tuaj yeem tswj hwm nws cov qauv qub thaum xav tau cov khoom ruaj khov, xws li insoles thiab insoles thiab gaskets.

7. Elasticity:
Elasticity yog cov khoom siv lub peev xwm rov qab mus rau nws tus qauv qub tom qab deformation, qee zaum hu ua rexound. Qee hom npe txuas ntxiv faib rau hauv ob ntu: Cushioning thiab Resilience. Lub ncoo rau hais txog cov ntaub ntawv muaj peev xwm los nqus tej yam kev cuam tshuam lub zog, thaum lub peev xwm resilience yog cov khoom siv tau txais txiaj ntsig sai tom qab lub zog. Qhov kev ua tau zoo no tshwj xeeb tshaj yog cov khau kis las, poob siab-nqus cov ntaub qhwv, thiab cov khoom siv kis las, qhov twg muaj kev tiv thaiv kis las yog qhov kev tiv thaiv zoo.

Los ntawm cov ntaub ntawv ntsuas kev ua haujlwm ntawm lub cev, peb tuaj yeem nkag siab cov yam ntxwv ntawm EVA thiab xaiv cov khoom lag luam tsim nyog raws li kev thov sib txawv, ua kom muaj kev ua tau zoo thiab zoo ntawm cov khoom kawg.
