Hunhu uye kupatsanurwa kweEVA mabhegi uye EVA mabhokisi

EVA ipurasitiki zvinhu zvinoumbwa ne ethylene (E) uye vinyl acetate (VA). Chiyero chemakemikari maviri aya anogona kugadziriswa kuti asangane nezvinodiwa zvakasiyana zvekushandisa. Iyo yepamusoro iyo yemukati yevinyl acetate (VA yemukati), iyo yakakwirira kujeka kwayo, kupfava uye kuoma kuchave.

Hunhu hweEva uye PEVA ndeidzi:

1. Biodegradable: Hazvizokuvadza zvakatipoteredza kana zvaraswa kana kupiswa.

2. Zvakafanana nePVC mutengo: EVA inodhura kupfuura PVC ine chepfu, asi yakachipa kupfuura PVC isina phthalates.

3. Kureruka: Kuwanda kweEVA kunotangira kubva ku0.91 kusvika ku0.93, nepo PVC iri 1.32.

4. Kusanhuhwirira: EVA haina ammonia kana zvimwe zvinhu zvinonhuhwirira.

5. Heavy metal-isina: Inopindirana nemitemo yematoyi yepasirese yakakodzera (EN-71 Chikamu 3 uye ASTM-F963).

6. Phthalates-isina: Yakakodzera matoyi evana uye haizokonzeresa njodzi yekuburitswa kweplasticizer.

7. Kujeka kwepamusoro, kupfava uye kuoma: chiyero chekushandisa chakakura kwazvo.

8. Super yakaderera tembiricha kuramba (-70C): yakakodzera icing nharaunda.

9. Kuramba kwemvura, munyu uye zvimwe zvinhu: inogona kuramba yakagadzikana muhuwandu hwemashandisirwo.

10. High heat adhesion: inogona kusungirirwa zvakasimba kune nylon, polyester, canvas nemamwe machira.

11. Low lamination tembiricha: anogona kukurumidza kugadzirwa.

12. Inogona kudhindwa skrini uye kudhindwa: inogona kushandiswa kune zvimwe zvigadzirwa zvemhando yepamusoro (asi inofanira kushandisa EVA inki).

EVA lining, sekureva kunoita zita, chimwe chigadzirwa chakaiswa mubhokisi iri EVA, uye ipapo pasuru inodiwa kunze, uye EVA lining inoiswa mupakeji iyi. Iyi pasuru inogona kunge iri simbi simbi bhokisi, kana chena kadhibhokisi bhokisi kana katoni.

Material classification yeEVA yekurongedza lining

EVA yekurongedza lining yakakamurwa zvakanyanya mune anotevera mapoinzi:

1. Yakaderera density, yakaderera density zvakatipoteredza ushamwari EVA, dema, chena uye ruvara.

2. High-density, high-density yezvakatipoteredza inoshamwaridzana EVA, dema, chena uye ruvara.

3. EVA yakavhara sero 28 madhigirii, 33 madhigirii, 38 madhigirii, 42 madhigirii.

4. EVA yakazaruka sero 25 madhigirii, 38 madhigirii
