Ni ibihe bintu bigena ubwiza bw'isakoshi ya EVA?

Nkibikoresho bisanzwe bipakira, ubuziranenge bwaImifuka ya EVAni ingaruka ku bintu byinshi. Hano hari ibintu by'ingenzi bigena hamwe ubuziranenge n'imikorere y'imifuka ya EVA:

1. Ibigize ibikoresho
Ubwiza bwimifuka ya EVA buterwa mbere nibigize ibintu, cyane cyane ibirimo Ethylene-vinyl acetate (VA). EVA ni ibikoresho bikozwe na copolymerisation ya Ethylene na vinyl acetate, kandi ibirimo VA muri rusange biri hagati ya 5% na 40%. Ingano ya VA igira ingaruka ku buryo butaziguye imikorere yimifuka ya EVA, nko guhinduka, kurwanya ingaruka, gukorera mu mucyo, nibindi.

2. Imiterere ya molekile
Imiterere ya molekulari ya EVA nayo igira uruhare runini mubwiza. Nyuma yo kwinjiza vinyl acetate monomer mumurongo wa molekulari ya EVA, kristu yo hejuru iragabanuka kandi ubukana ningaruka zo kurwanya ingaruka ziratera imbere. Kubwibyo, imiterere ya molekulari yimiterere yimifuka ya EVA ningirakamaro mubikorwa byabo.

3. Inzira yumusaruro
Igikorwa cyo gukora imifuka ya EVA nacyo ni ikintu cyingenzi. Ibigo byinshi bikoresha umuvuduko mwinshi uhoraho polymerisiyonike, harimo uburyo bwa keteti nuburyo bwa tubular. Itandukaniro muribi bikorwa rizaganisha ku itandukaniro mumikorere yibicuruzwa bya EVA, nko kurwanya ihungabana no gusaza.

4. Gutunganya no kubumba
EVA ni polymer ya thermoplastique ishobora gukoreshwa muburyo butandukanye bwo gutunganya no kubumba nko guterwa inshinge, gushushanya ibicuruzwa, no guhuha. Ifumbire ya EVA ifite ubushyuhe buke bwo gutunganya (160-200 ℃), intera nini, n'ubushyuhe buke (20-45 ℃). Ibi bintu byo gutunganya bizagira ingaruka kumiterere yanyuma yumufuka wa EVA.

5. Ubucucike no gukomera
Ubucucike bwumufuka wa EVA mubusanzwe buri hagati ya 0,9-0,95 g / cm³, kandi ubukana busanzwe bugeragezwa ukoresheje Shore A ubukana, hamwe nuburemere busanzwe buri hagati ya 30-70. Ibipimo byimikorere bifatika bifitanye isano itaziguye nimbaraga nogusunika imikorere yumufuka wa EVA.

6. Imikorere y'ibidukikije
Imifuka ya EVA igomba kuba yujuje ibyangombwa byo kurengera ibidukikije, ikabamo ibintu byangiza, kandi ikurikiza amahame n’ibidukikije bijyanye. Imikorere y'ibidukikije ni ikintu abaguzi ba kijyambere barushaho guhangayikishwa no guhitamo ibicuruzwa.

7. Igishushanyo
Igishushanyo cyumufuka wa EVA nacyo kizagira ingaruka kumiterere yacyo. Igishushanyo kirimo guhitamo imyenda, ubunini n'ubukomere bya EVA, hamwe n'ibishushanyo mbonera by'ibicuruzwa. Igishushanyo cyiza kirashobora kunoza imikorere nuburanga bwimifuka ya EVA.

8. Kurwanya kwikuramo no kurwanya ihungabana
Imifuka ya EVA igomba kuba ifite imbaraga zo kurwanya no guhungabana kugirango irinde ibintu bipfunyitse ingaruka zituruka hanze

9. Kurwanya amazi no kurwanya ruswa
Imifuka yo mu rwego rwohejuru ya EVA igomba kugira amazi meza no kurwanya ruswa, kandi ikabasha kurwanya ruswa ituruka ku nyanja, amavuta, aside, alkali nindi miti

Muri make, ubwiza bwimifuka ya EVA bugenwa nibintu byinshi nkibigize ibintu, imiterere ya molekile, inzira yumusaruro, gutunganya no kubumba, imitungo yumubiri, imikorere yo kurengera ibidukikije, gushushanya, kurwanya compression no kurwanya ihungabana, kimwe no kurwanya amazi no kwangirika. kurwanywa. Ababikora bakeneye gutekereza kuri ibyo bintu byose kugirango babone imifuka myiza ya EVA.
