Nigute ushobora gupima ubwiza bwimifuka ya EVA?

Ikizamini cyiza cyaImifuka ya EVAni inzira yuzuye yo gusuzuma ikubiyemo ibintu byinshi, harimo imiterere yumubiri, imiterere yimiti, ibipimo byo kurengera ibidukikije nibindi bipimo. Ibikurikira nibintu bimwe byingenzi byizamini nuburyo bukurikira:

1. Ikizamini cyimikorere yumubiri
Ikizamini cyimikorere isuzuma cyane cyane imiterere yumubiri yimifuka ya EVA, harimo:

Ikizamini gikomeye: Ubukomezi bwimifuka ya EVA busanzwe bugeragezwa na Shore Ikizamini gikomeye, kandi urwego rukomeye ruri hagati ya 30-70

Imbaraga zingana no kurambura kuruhuka: Imbaraga zingana no kuramba mugihe cyo kumena ibikoresho bipimwa nikizamini cya tensile kugirango kigaragaze imiterere yubukanishi hamwe numutekano wumufuka wa EVA

Kwipimisha burundu ikizamini cyo guhindura ibintu: Menya ihindagurika rihoraho ryibintu munsi yigitutu runaka kugirango umenye igihe kirekire cyumufuka wa EVA

2. Ikizamini cyo gukora ubushyuhe
Ikizamini cyimikorere yubushyuhe cyibanze kumikorere yimifuka ya EVA mubihe byubushyuhe bwinshi:

Gushonga hamwe nubushyuhe bwumuriro: Ingingo yo gushonga hamwe nubushyuhe bwubushyuhe bwibikoresho bya EVA bisuzumwa na calorimetrie itandukanye (DSC) hamwe nisesengura rya termogravimetric (TGA)

Ubushyuhe bwo gusaza: Gerageza gusaza imifuka ya EVA mubushuhe bwo hejuru kugirango umenye neza ko ibicuruzwa bishobora gukomeza gukora neza nyuma yo gukoresha igihe kirekire

3. Ikizamini cyo gukora imiti
Ikizamini cyimikorere yimiti isuzuma ubukana bwumufuka wa EVA kubintu byimiti:

Kurwanya ruswa ya chimique: isuzuma irwanya umufuka wa EVA kuri aside, alkali, umunyu nibindi bintu bya shimi

Kurwanya amavuta: kugerageza guhagarara no kwangirika kwumufuka wa EVA muburyo bwa peteroli

4. Ikizamini cyo kurwanya ibidukikije
Ikizamini cyo kurwanya imihindagurikire y’ibidukikije gisuzuma guhuza imifuka ya EVA n’ibidukikije:

Ikizamini cyo guhangana nikirere: cyerekana guhangana n umufuka wa EVA kumirasire ya ultraviolet, ubuhehere nubushyuhe

Ikizamini cyo kurwanya ubushyuhe buke: gisuzuma imikorere yumufuka wa EVA mubushyuhe buke

5. Ikizamini gisanzwe cyibidukikije
Ikizamini gisanzwe cy’ibidukikije cyemeza ko umufuka wa EVA wujuje ibyangombwa by’ibidukikije kandi utarimo ibintu byangiza:

Amabwiriza ya RoHS: Amabwiriza abuza ikoreshwa ryibintu bimwe na bimwe bishobora guteza akaga ibikoresho byamashanyarazi na elegitoroniki. Gukoresha ibikoresho bya EVA mubikoresho bya elegitoronike bigomba kubahiriza aya mabwiriza

REACH Amabwiriza: Amabwiriza y’ubumwe bw’ibihugu by’Uburayi yerekeye kwandikisha, gusuzuma, gutanga uburenganzira no kugabanya imiti. Umusaruro nogukoresha ibikoresho bya EVA bigomba kubahiriza ibisabwa nubuyobozi bwa REACH

6. Ikizamini cyo kohereza no gukuramo imbaraga
Ibizamini bidasanzwe bya firime ya EVA:

Ikizamini cyo kohereza: gusuzuma urumuri rwa firime ya EVA, rukaba ari ingenzi cyane kubisabwa nka panneaux solaire

Ikizamini cyimbaraga zipima: gerageza imbaraga zishishwa hagati ya firime ya EVA nikirahure nibikoresho byinyuma kugirango umenye neza ko gupakira

Binyuze mubintu byavuzwe haruguru, ubuziranenge bwibikoresho bya EVA birashobora gusuzumwa neza kugirango byemeze ko bikenewe muburyo butandukanye bwo gusaba. Mugihe cyo gukora no gukoresha ibikoresho bya EVA, ibigo bigomba kubahiriza byimazeyo amahame mpuzamahanga, igihugu ndetse ninganda kugirango ibicuruzwa byujuje ubuziranenge n'umutekano
