Nzira yekuyedza mhando yemabhegi eEva?

Kuedzwa kwehutano hweEVA masagainzira yekuongorora yakazara inosanganisira akawanda maficha, anosanganisira zvimiro zvemuviri, zvimiro zvemakemikari, mazinga ekuchengetedza kwezvakatipoteredza uye humwe hukuru. Izvi zvinotevera zvimwe zvakakosha bvunzo zvinhu uye nzira:

1. Muedzo wekuita muviri
Muedzo wekuita kwemuviri unonyanya kuongorora izvo zvakakosha zvemuviri zveEVA mabhegi, anosanganisira:

Kuomarara bvunzo: Kuomarara kwemabhegi eEVA kunowanzo kuedzwa neShore A kuomarara bvunzo, uye yakajairika kuomarara renji iri pakati pe30-70.

Kusimba kwesimba uye kureba panguva yekuzorora: Kusimba kwesimba uye kurebesa pakupwanyika kwezvinhu kunoyerwa neakasimba bvunzo kuratidza mashandiro emuchina uye kugadzikana kwebhegi reEVA.

Kudzvanya kusingaperi deformation bvunzo: Sarudza iyo compression yekusingaperi deformation yechinhu pasi peimwe dzvinyiriro yekuongorora kusimba kweiyo EVA bhegi.

2. Thermal performance test
Iyo thermal performance test inotarisa pakuita kwemabhegi eEVA pasi pemamiriro ekushisa akanyanya:

Melting point uye thermal stability: Nzvimbo yekunyungudika uye kugadzikana kwekupisa kwezvinhu zveEVA zvinoongororwa nekusiyanisa scanning calorimetry (DSC) uye thermogravimetric analysis (TGA)

Heat kuchembera kuramba: Edza kuramba kuchembera kwemabhegi eEVA munzvimbo dzakanyanya tembiricha kuti uone kuti chigadzirwa chinogona kuramba chichiita zvakanaka mushure mekushandisa kwenguva refu.

3. Muedzo wekuita kwemakemikari
Chemical performance test inoongorora kuramba kweEVA bhegi kumakemikari zvinhu:

Chemical corrosion resistance: inoongorora kuramba kweEVA bhegi kune acid, alkali, munyu uye zvimwe zvinhu zvemakemikari.

Oiri kuramba: inoedza kugadzikana uye kushora kuramba kweEVA bhegi mune oiri medium

4. Environmental adaptability test
Muedzo wekuchinjika kwezvakatipoteredza unoongorora kuchinjika kweEVA bhegi kune zvakatipoteredza zvinhu:

Weather kuramba bvunzo: inoona kuramba kweEVA bhegi kune ultraviolet mwaranzi, humidity uye tembiricha shanduko

Yakadzika tembiricha yekudzivirira bvunzo: inoongorora mashandiro eVA bhegi munzvimbo yakaderera tembiricha

5. Environmental standard test
Environmental standard test inovimbisa kuti EVA bhegi rinosangana nezvinodiwa zvezvakatipoteredza uye harina zvinhu zvinokuvadza:

RoHS Directive: Directive inorambidza kushandiswa kwezvimwe zvinhu zvine njodzi mumagetsi nemagetsi midziyo. Iko kushandiswa kwezvinhu zveEVA mumidziyo yemagetsi kunoda kutevedzera kuraira uku

REACH Regulation: Mitemo yeEU pakunyoresa, kuongorora, mvumo uye kudziviswa kwemakemikari. Kugadzirwa uye kushandiswa kwezvinhu zveEVA zvinoda kuenderana nezvinodiwa zveREACH Regulation

6. Transmittance uye peel simba bvunzo
Miedzo yakakosha yeEVA firimu:

Transmittance bvunzo: inoongorora iyo mwenje transmittance yeEVA firimu, iyo inonyanya kukosha kune maapplication akadai solar panels.

Peel simba bvunzo: inoedza iyo peel simba pakati peEVA firimu negirazi uye backplane zvinhu kuti ive nechokwadi chekuvimbika kwekurongedza.

Kuburikidza nezvinhu zvebvunzo zviri pamusoro, mhando yeEVA mapakeji inogona kuongororwa zvizere kuti ive nechokwadi chekuti inosangana nezvinodiwa zveakasiyana maficha ekushandisa. Paunenge uchigadzira uye uchishandisa EVA zvinhu, makambani anofanirwa kunyatso kutevedzera akakodzera epasirese, nyika uye indasitiri zviyero kuti ave nechokwadi chemhando yechigadzirwa uye kuchengetedzeka.
