I. Zvakafanana :
Kunyangwe ari maviri akasiyana zvinhu, anogovana zvakafanana mune macroscopic fomu uye zvimwe zvakakosha zvivakwa:
Porous structure: Zvose zvinogadzirwa kuburikidza nekupupuma kwemakemikari emuviri kana kemikari uye zvinozadzwa neyunifomu kana kusaenzana maseru mukati, izvo zvinoita kuti ese ari maviri akareruka, aite zvekuvhunduka{0}}uye kupisa{1}}kupisa.
Elasticity: Semiviri yakanyunguduka, ese ari maviri anogona kudzoka kune imwe nhanho uye kudzokera kune yavo yekutanga mushure mekumanikidzwa.
Kugoneka: Zvese zvinogona kuumbwa nekudzvanya mukati me mold kugadzira zvakasiyana-siyana-zvigadzirwa zvakaita semagaskets, soles, floor MATS, nezvimwe.
Kuiswa kwemagetsi uye kuramba kwemvura: Zvese mushure mekupupa zvine yakanakisa magetsi ekudzivirira uye kudzivirira kwemvura zvivakwa.
II.Kusiyana:
1. Material Nature uye Mariro: EVA inogadzirwa kubva kune petrochemicals. Zvigadzirwa zvayo zvinowanikwa zvakanyanya uye maitiro ayo ekugadzira (senge imwe-nguva yekupupa uye kuumba yechipiri) yakura. Naizvozvo, mutengo wayo wakaderera zvakanyanya uye wakakodzera zvinhu zvevatengi vakawanda. Silica gel yakadzika-yakagadzirwa chigadzirwa chesilicon dioxide. Zvishandiso zvayo zvekushandisa uye maitiro ekugadzirira (senge platinum catalytic foaming) yakaoma uye mutengo wakakwira zvakanyanya.
2. Kupisa kupisa uye kunonoka kwemurazvo (musiyano wakanyanya kukosha) EVA chinhu che thermoplastic. Kana yaiswa kune tembiricha yepamusoro (sekupfuura 70-80 degrees ), inopfava, kunyunguduka, uye kunyange kupisa nekudonha, nokudaro kushaya simba remurazvo. Ichi ndicho chikonzero chakakosha nei isingambofa yakashandiswa munzvimbo dzinopisa zvakanyanya. Silicone ndeye thermosetting zvinhu ine yakanyanyisa kupikisa kune yakanyanya kukwira uye yakaderera tembiricha. Inogona kushanda kwenguva yakareba pa 250℃uye inogona kumira tembiricha iri pamusoro pe300℃kwenguva pfupi. Panguva imwecheteyo, ine yakakwira murazvo wegiredhi retardant (kusvika kuUL94 V-0 level), inodzima pakarepo kana yabviswa kubva pamoto sosi, haiburitse madonhwe akanyungudutswa, uye ine yakanyanya kuchengetedzwa.
3. Ushamwari hwezvakatipoteredza uye kuchengeteka: Unhu hweEVA hunosiyana zvikuru. Yepamusoro-EVA yemhando yepamusoro inogona kusanhuhwirira, asi yakaderera-EVA yemhando yepamusoro inogona kushandisa zvinhu zvakagadzikiswazve uye zvinopupuma furo, zvichikonzera kusara kunhuhwa uye zvinhu zvinokuvadza (senge formamide). Silicone haina muchetura uye haina kunhuwa, ine zvimiro zvemakemikari zvakagadzikana uye haibudisi zvinhu zvinokuvadza. Inogona kupasa zvitupa zvakaomesesa seFDA (Chikafu neDrug Administration yeUnited States) uye LFGB (European Union Chikafu Giredhi), uye inoshandiswa zvakanyanya munzvimbo dzekurapa uye dzekudya.
4. Durability uye Compression Set Imwe hombe drawback EVA ndiyo yakakura compression set. Zvichitaurwa zviri nyore, iyo EVA insole ichave yakapfava mushure mekupfekwa kwenguva refu, isingakwanise kudzoka kune yayo yepakutanga ukobvu uye kurasikirwa kwayo elasticity. Iko compression set value yesilicone yakadzikira zvakanyanya, zvinoreva kuti inogona kudzoka zvachose kune yayo yekutanga mushure mekudzvanywa kwenguva yakareba. Kugara kwayo uye hupenyu hwesevhisi kupfuura izvo zveEva.
