Eva Wax (inopisa inonyungudika yakanamira) ine huwandu hwakasiyana hwekushanda, senge PA (polypropylene),

PE (polyethylene) uye zvimwe zvisiri-polar zvinhu, asi zvakare inogona kuwana yakanaka yekubatanidza maitiro.

Iyo adhesive layer ine yakanaka yakaderera tembiricha kuramba, kudzivirira mvura uye mwando

kusagadzikana.

Nekuti EVA wakisi (inopisa inonyungudika yakanamira) haina kusimba, ine yakaderera kupfava poindi kupfuura.

polyester uye polyamide inopisa inonyunguduka inonamatira, uye nzvimbo yayo yekunyorovesa yepasi rose inenge 100 °C, saka

mashandisirwo ayo akasiyana.

Eva Wax (inopisa inonyungudika yakanamira) inoumbwa neEva resin, tackifying resin, wakisi uye stabilizer.

Eva resin yakaunza maketani mapfupi ane matavi anoumbwa ne polar acetic acid genes mukati

ethylene branched cheni, iyo yakavhiringidza yepakutanga crystalline state, yakaita kuti EVA aite

"Plasticizing effect", uye yakaderedza crystallinity ye ethylene mumaketani ane mapazi,

wedzera chinhambwe pakati pepolymer cheni, zvichiita kuti EVA resin iwedzere kushanduka uye

elastic.

Izvo zviri mukati meVA muEva resin zvinogona kubva pasi kusvika pakakwirira muzana. Naizvozvo, the

muzana yeVA uye MI (inonyungudika indekisi, inoratidza huremu hwemamorekuru) muresin ndiyo

zvakanyanya kukosha zvinhu zvinotarisa uye zvinokanganisa zvimiro zveEva.

Kazhinji, Eva zvemukati zvakakwirira, simba rekunamatira rinowedzerwa, kunyorova kweanonamatira

zvinhu zvakanaka, nguva yekurapa inononoka, kupisa kupisa kunoderera. Iyo yekunyunguduka index yakakwira,

zvinoreva kuderera kwema molecular weight, low viscosity, kunaka kunyorova, kushomeka kwekupisa,

kunamatira nguva dzose.

Mune ethylene-based copolymers, Eva ane yakakwira tensile simba kupfuura EEA (ethylene-Ethyl

acrylate), EAA (ethylene-propylene ester) uye EMA (ethylene-propylene ester), uye iyo

inosiyana nezviri muVA.Kana iyo Mi yeEVA yakasiyana, shanduko yekupwanya tensile

simba rakawanda.

Kusimba kwekusimba kweEva wax kunodzikira nekuwedzera kweVA yemukati, uye inova

idiki kwazvo kana VA yemukati inopfuura 25%.

Iyo flexural rigidity yeEVA yakafanana neyePVC yakapfava. Inoderera nekuwedzera kwe

VA, Nekuwedzera kweMI, kugonda kusimba kunoderera.

Eva resin ine kuenderana kwakanaka, inogona kusanganiswa nemamwe marudzi eresin kugadzirisa

zvinhu zvemuviri. Kana Eva resin uye nitrocellulose zvakasanganiswa, nitrocellulose ine f

lexibility, friction resistance uye kupisa-kuisa chisimbiso.

Yakaoma PVC yakasanganiswa ne5% ~ 10% EVA yakavandudza fluidity uye yakavandudza maitiro

resistance. Eva yakasanganiswa muPolyamide resin ine yakanaka flexure resistance uye stain resistance

panguva yakaderera tembiricha.
