I. Qhov zoo sib xws:
Txawm hais tias lawv yog ob yam khoom sib txawv, lawv muab cov lus sib xws hauv macroscopic form thiab qee yam yooj yim:
Cov qauv ntxeem tau: Ob leeg yog tsim los ntawm cov txheej txheem ua npuas ncauj thiab muaj cov hlwb tsis sib xws sab hauv, uas ua rau lawv muaj kev chim siab thiab kub}-} insulating.
Elasticity: zoo li lub cev elastic, ob leeg tuaj yeem rov qab mus rau qee yam thiab rov qab mus rau lawv cov qub lub xeev tom qab tau compressed.
Cov khoom lag luam kub ua tau los ntawm kev nias kub los ntawm cov pwm los tsim ntau yam khoom siv ntau yam, xws li gaskets, khau, thiab lwm yam.
Hluav taws xob rwb thaiv tsev thiab dej tsis kam: ob qho tib si tom qab ua npuas dej tau muaj hluav taws xob hluav taws xob zoo heev.
Ii.dorterences:
1. Cov Khoom Siv Xwm thiab tus nqi: EVA yog cov khoom lag luam ntawm petrochemicals. Nws cov ntaub ntawv nyoos muaj dav muaj thiab cov txheej txheem tsim khoom (xws li ib- foaming thiab moulding) tau paub tab. Yog li ntawd, nws tus nqi yog tsawg heev thiab nws yog qhov haum rau cov neeg siv khoom loj. Silica gel yog ib qho tob tob- Cov khoom lag luam ntawm silicon dioxide. Nws cov ntaub ntawv nyoos thiab kev npaj cov txheej txheem (xws li platinum catalytic catalytic foaming) yog qhov nyuaj thiab tus nqi yog heev.
2. Cua sov kuj thiab nplaim taws retardancy (qhov tseem ceeb tshaj plaws sib txawv) EMA yog cov khoom siv thermoplastic. Thaum raug rau qhov kub (xws li tshaj 70 {{{}} 80}} 80}), nws yuav muag, thiab txawm tsis muaj nplaim retardancy. Qhov no yog vim li cas vim li cas nws yuav tsum tsis txhob siv rau hauv qhov chaw siab-ib puag ncig. Silicone yog cov khoom siv thickosetting nrog kev tsis tshua muaj kev tsis tshua muaj siab heev rau huab siab siab thiab qis kub. Nws tuaj yeem ua haujlwm ntev ntawm 250℃thiab tuaj yeem tiv taus kub siab tshaj 300 qib rau lub sijhawm luv. Nyob rau tib lub sijhawm, nws muaj cov nplaim hluav taws xob siab Retardant Qib (tau txog ul94 v-0 qib tam sim ntawd thaum tshem tawm cov tee hluav taws tam sim ntawd, thiab muaj kev nyab xeeb heev.
3. Ib puag ncig kev phooj ywg thiab kev nyab xeeb: qhov zoo tshaj ntawm Eva tau sib txawv heev. Siab - Zoo EVA tuaj yeem siv tsis muaj ntxhiab, tab sis cov neeg sawv cev tsis zoo thiab cov khoom siv tsis zoo (xws li formamide). Silicone yog inherently tsis yog- ua kom lom thiab tsw, nrog cov tshuaj muaj kev phom sij thiab tsis tshua muaj kev phom sij. Nws tuaj yeem dhau cov ntawv pov thawj nruj tshaj plaws xws li FDA (Food thiab LFGB (European Union zaub mov qib kawm), thiab yog siv cov chaw noj mov thiab cov zaub mov sib ze.
4. Durability thiab compressress teeb ib qho loj drawback ntawm eva yog nws cov txheej txheem loj compression teeb. Cias muab, ib qho eva insole yuav pluav tom qab hnav rau lub sijhawm ntev, tsis tuaj yeem rov qab mus rau nws cov qub tuab thiab poob nws elasticity. Lub compression teeb tus nqi ntawm silicone yog qhov tsawg heev, uas nws tuaj yeem yuav luag rov qab los rau nws thawj lub xeev tom qab tau squeezed ntev. Nws cov kav ntev thiab kev pabcuam lub neej deb tshaj li ntawm EVA.
