Nyob zoo, sawv daws!Cov thawv ntim khoom ib txwm yog qhov tseem ceeb ntawm peb lub neej thaum nws los txog rau kev tiv thaiv thiab tso saib cov khoom.Niaj hnub no, kuv xav qhia koj txog cov khoom ntim uas muaj kev hwm heev - EVA ntim lub thawv.
EVA, uas sawv cev rau ethylene vinyl acetate, yog siv dav hauv kev lag luam ntim khoom vim nws cov elasticity zoo heev thiab cuam tshuam tsis kam.Yog li, dab tsi yog qhov txawv ntawm nws thiab ib txwm ntim thawv?
Ua ntej tshaj plaws, kev tiv thaiv kev ua haujlwm ntawm EVA ntim lub thawv yog zoo heev.Vim muaj cov khoom siv hauv lub cev, EVA cov thawv ntim tau zoo nqus kev poob siab thiab kev co, muab kev tiv thaiv zoo rau cov khoom.Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog rau cov khoom tawg yooj yim thiab cov khoom muaj txiaj ntsig siab.Txawm hais tias nws yog pob thiab tee thaum thauj, los yog stacking thiab compression thaum lub sij hawm cia, EVA thawv tiv thaiv cov khoom los ntawm kev puas tsuaj.
Thib ob, EVA ntim cov thawv muab ntau yam, hloov tau tsim kev xaiv kom tau raws li qhov xav tau ntawm ntau yam khoom.Siv lub malleability ntawm EVA cov ntaub ntawv, manufacturers tuaj yeem kho cov duab thiab cov qauv ntawm lub thawv ntim raws li tus yam ntxwv thiab qhov loj ntawm cov khoom.Qhov no txhais tau hais tias EVA thawv tuaj yeem muab qhov zoo tshaj plaws haum thiab siv tau zoo tshaj plaws ntawm qhov chaw sab hauv, txhim kho qhov zoo nkauj ntawm cov khoom siv.
Ntxiv nrog rau kev tiv thaiv thiab tsim kev yooj yim, EVA thawv kuj hnav-resistant thiab dej-resistant.Txawm hais tias sab hauv tsev lossis sab nraum zoov, EVA ntim cov thawv tuaj yeem tiv thaiv kev hnav sab nraud thiab tiv thaiv kom tsis txhob ya raws, kom ntseeg tau tias cov khoom zoo thiab cov tsos ntawm cov khoom tsis zoo rau lub sijhawm ntev.
Thaum kawg, cia peb tsom mus rau ib puag ncig.Cov ntaub ntawv siv hauv kev tsim khoom ntawm EVA ntim cov thawv yog ib puag ncig tus phooj ywg thiab rov ua dua tshiab.Qhov no txhais tau hais tias los ntawm kev siv lub thawv EVA, peb tuaj yeem tsis tsuas yog txo peb cov kev cuam tshuam tsis zoo rau ib puag ncig, tab sis kuj pab txhawb kev txhim kho kom ruaj khov.
Tag nrho hauv tag nrho, EVA thawv tau txais txiaj ntsig zoo rau lawv cov khoom tiv thaiv zoo, kev xaiv tsim ntau yam, hnav tsis kam, dej tsis kam thiab ib puag ncig tus phooj ywg.Lawv yog cov saib xyuas ntawm cov khoom muag thiab cov neeg sawv cev ntawm cov khoom zoo nkauj.Xaiv lub thawv EVA ua kom ntseeg tau tias koj cov khoom tau saib xyuas tag nrho thiab nthuav tawm zoo nkauj, ua rau cov neeg siv khoom zoo siab txij li lub sijhawm lawv pom.
