Amakuru - Gukemura ibibazo bya EVA Foam

Mu myaka ya vuba aha, isoko ry’inkweto ku isi ryagaragayemo ubwinshi bw’inkweto, birushaho kwiyongera mu irushanwa hagati y’ibigo biciriritse kugeza ku bigezweho. Ukwiyongera gukomeye kw’ibitekerezo bishya n’ikoranabuhanga mu nkweto byatumye hakenerwa cyane ibikoresho byo gufuro mu nganda zikora inkweto. Ibikoresho byo gufuro bya polymer bifite imikorere myiza byabaye inkingi y’ingenzi y’ibisubizo byinshi by’ibicuruzwa bya terminal, cyane cyane mu rwego rw’inkweto za siporo.

Inkweto zisanzwe za siporo zigizwe n'ibice bitatu by'ingenzi: inkweto zo hejuru, inkweto zo hagati n'izisohoka.

Igice cyo hagati ni ingenzi mu gutanga umusego, gusubira inyuma no gufata imbaraga mu gihe cy'imikino. Gitanga uburinzi n'ibyiyumvo byiza, bigatuma inkweto za siporo ziba nziza. Ikoranabuhanga ry'ibikoresho n'ifuro ry'igice cyo hagati ritandukanya ikoranabuhanga ry'ingenzi ry'ibigo bikomeye bitandukanye.

EVA—Igikoresho cya mbere cyakoreshejwe mu gushushanya inkweto:

Ethylene-vinyl acetate copolymer (EVA) ni yo foam ya mbere ikoreshwa mu bice by'imbere. Foam ya EVA yuzuye ubusanzwe ifite ubushobozi bwo gusubiramo hagati ya 40-45%, irusha ibikoresho nka PVC na rubber mu kwihanganira, hamwe n'ibintu nk'ibyoroshye kandi byoroshye gutunganya.

Mu rwego rw'inkweto, uburyo bwo gusohora ifuro hakoreshejwe imiti ya EVA muri rusange burimo ubwoko butatu: gusohora ifuro rinini risanzwe, gusohora ifuro rito rikozwe mu ibumba, no gusohora ifuro rihuza inkweto.

Kuri ubu, gukoresha ifuro mu gutera inshinge byahindutse inzira nyamukuru mu gutunganya ibikoresho by'inkweto.

Imbogamizi za EVA Foam:

Ikibazo gikunze kugaragara kuri izi furo za EVA zisanzwe ni ubushobozi bwazo bwo kutagorama, bigira ingaruka ku bushobozi bwazo bwo gutanga umusego mwiza no gushyigikira, cyane cyane mu nkweto za siporo. Indi mbogamizi ikunze kugaragara ni ukubaho kw'ingufu no kugabanuka k'ubushyuhe uko igihe kigenda gihita, bigira ingaruka ku kuramba. Byongeye kandi, mu gihe ifuro rya EVA ridashobora kunyerera no kudashwanyagurika ari ngombwa, ifuro rya EVA risanzwe rishobora kutubahiriza ibisabwa.

Kugira ngo barusheho kunoza imiterere y’ibicuruzwa bya EVA foam, abakora bakunze gushyira ibikoresho bya elastic nka EPDM, POE, OBC, na TPE nka SEBS mu bikoresho fatizo bya EVA. Gushyira EPDM mu miterere ya rubber, POE mu buryo bworoshye, OBC mu buryo bworoshye, TPE mu buryo bworoshye, nibindi, bigamije kugera ku ntego zo guhindura. Urugero, iyo wongeyeho POE elastomers, ubushobozi bwo kongera ubushobozi bw’ibicuruzwa akenshi bushobora kwiyongera bukagera kuri 50-55% cyangwa bukarenga.

Udushya EVA Foam: Si-TPV Modifier kugira ngo irusheho kuba nziza kandi irusheho kunozwa

SILIKE Si-TPV itanga ubundi buryo muri EVA, ntabwo ikemura ibibazo by'imikorere gusa ahubwo inahuza n'ibikorwa birengera ibidukikije. Imiterere yayo mishya n'uburyo bwo kuyitunganya bigira uruhare mu gutuma ibicuruzwa bigumana ubuziranenge n'imikorere yabyo mu gihe kirekire, bigatuma byizewe kandi biramba, bigatuma ibicuruzwa birangira neza kandi bikagira agaciro kenshi.

Si-TPV (vulcanizate thermoplastic silicone-based elastomer) ni ibikoresho bya elastomer bishobora kongera gukoreshwa 100%, Ugereranyije na OBC na POE, bigabanya cyane uburyo bwo gukanda no gushonga k'ubushyuhe bw'ibikoresho bya EVA foam. Ibigaragara cyane byazamuye uburyo bworoshye bwo gukaraba, bworoshye, burwanya kunyerera, kandi bugatuma DIN idasaza kuva kuri mm 580.³kugeza kuri mm 179³.

Byongeye kandi, Si-TPV yongera amabara y’ibikoresho bya EVA foam. Iri terambere rituma abakora ibikoresho bashobora gukora ibintu biryoshye bitabangamiye imikorere.

Iyi Si-TPV nk'uburyo bwo guhindura udushya kuri EVA foam ifasha mu gukora ibintu bigezweho kandi biramba bijyanye na EVA foam nk'imisatsi yo hagati, ibikoresho by'isuku, ibikoresho byo kwidagadura mu mikino, hasi, imitako ya yoga, n'ibindi.

Menya ahazaza ha EVA Foam ukoresheje SILIKE Si-TPV! Zamura ibicuruzwa byawe ku rwego rwo hejuru rw'imikorere n'ubwiza. Ongera imbaraga za Si-TPV modifier yacu igenda ihinduka kugira ngo ubone amahirwe adasanzwe muri porogaramu zawe za EVA foam.

Twandikire uyu munsi kugira ngo utangire urugendo rwo guhanga udushya no gusobanura neza ibishoboka ukoresheje EVA foam!
