Mu ruhererekane rw'udushya turimo gukorwa mu nganda zikora inkweto ku isi, ibikoresho bihuza ubushobozi bwo kwihanganira inkweto za kawunga n'uburyo zitunganywa neza bwa pulasitiki biri kuyobora mu mpinduka zikomeye - ethylene-vinyl acetate copolymer, izwi nka EVA. Nk'inkingi y'ikoranabuhanga rya none ry'ibikoresho by'inkweto, EVA, ifite imiterere yihariye y'ifuro ifite imyenge, ubushobozi bworoshye bwo gukaraba, hamwe no kwihuza neza n'imiterere, irimo kuvugurura imipaka y'imikorere no kwambara inkweto - kuva ku myenda y'umwuga kugeza ku nkweto zigezweho.

Ibiranga by'ingenzi: Impinduka mu buhanga mu gushushanya inkweto

Ibyiza by'ingenzi bya EVA mu nganda z'inkweto bikomoka ku miterere yayo ihinduka neza ndetse n'imiterere yayo ifatika. Mu kugenzura uburyo ifuro rikorwa, ubucucike bw'ibikoresho bushobora guhindurwa mu buryo bworoshye hagati ya 0.03 na 0.25g/cm³, bigatanga ibisubizo byihariye ku bwoko butandukanye bw'inkweto:

1.Umusego wa nyuma:Imisozi ya EVA ifite ubushobozi bwo kuzamuka cyane ishobora kugera ku gipimo cyo kugaruka kw'ingufu kuva kuri 55% kugeza kuri 65%, ikanyunyuza neza imbaraga z'ingaruka mu gihe cyo kugenda no kugabanya uburemere bw'ingingo ku kigero cya 30%.

2.Ubunararibonye bworoheje:Kugeza kuri 40%–50% byoroheje ugereranyije n'ingufu gakondo za kabutike, bikongera ihumure mu gihe cyo kwambara igihe kirekire no kwihuta mu mikino.

3.Kuramba no Guhagarara:Imiterere y’uturemangingo dufunze itanga ubudahangarwa bwiza bwo guhangana n’ihindagurika ry’ingufu (<10%), bigatuma igitenge gikomeza kuba cyiza nubwo cyakoreshwa igihe kirekire.

4.Guhuza n'ibidukikije: Imiti irwanya ikirere ikomeza gukora neza mu bushyuhe bukabije kuva kuri -40°C kugeza kuri 70°C, ikaba ihinduka bitewe n’ikirere gitandukanye ku isi.

Udushya mu ikoranabuhanga: Kuva ku gusohora ifuro ry'ibanze kugeza ku gusubiza neza mu buryo bw'ubwenge

Laboratwari zikomeye ku isi zirimo gushyira ikoranabuhanga rya EVA mu gisekuru cyaryo cya gatatu:

1.Ikoranabuhanga ryo gupima ubucucike bw'umuvuduko:Igera ku bice byinshi by'ubucucike mu gice kimwe cy'inkweto (urugero, gusimbuka cyane mu gice cy'imbere cy'ikirenge, gupfuka cyane mu gatsinsino) kugira ngo ihuze n'ibikenewe mu buryo bufatika.

2.Ifuro ry'amazi ashyushye cyane:Ikoresha CO₂ cyangwa N₂ mu gusimbuza imiti ikoreshwa mu gusohora amazi, ikagenzura uburebure bw'imyenge kugeza kuri mikorometero 50–200 kandi ikongera uburinganire ku kigero cya 40%.

3.Sisitemu z'imikorere zivanze:Shyiramo uduce duto twa bagiteri (iyoni z'ifeza/okiside za zinki), udupira duto duhindura phase (ubushyuhe buri hagati ya 18–28°C), hamwe n'amabara meza asubiza.

4.Udushya durambye:EVA ishingiye kuri bio (ikomoka kuri ethanol y'ibisheke) igabanya ubwinshi bwa karuboni ku kigero cya 45%, aho sisitemu zo kongera gukoresha ibikoresho zifunganye zituma igipimo cyo kongera gukoresha ibikoresho kirenga 70%.

Imiterere y'Ikoreshwa: Impinduramatwara mu Mikorere mu Bice Byose by'Inkweto

Inkweto z'abakinnyi b'umwuga:

Inkweto zo mu marushanwa: Imisozi ya EVA ifite ifuro rikomeye cyane ifite ubucucike bwa 0.12–0.15 g/cm³ igera ku gipimo cyo kugarura ingufu >80%.

Inkweto za Basketball: Inkweto zo hagati zifite ibyiciro byinshi zituma urwego rw'imbere rugabanukaho 35%, aho urwego rw'inyuma rugera kuri 25 MPa.

Inkweto zo mu muhanda: Ingano nyinshi za VA (28%–33%) zigumana ubworoherane kuri -20°C, bigatuma zifata ahantu hanyerera.

Inkweto z'ubuzima n'imideli:

Inkweto Zisanzwe: Ikoranabuhanga rya micro-foaming ritanga ubunararibonye bwo gukoraho "bumeze nk'ibicu", rituma igitutu gikwirakwizwa ku kigero cya 22% mu gihe cy'amasaha 24 yo kwambarwa buri gihe.

Inkweto z'ubucuruzi: Sisitemu zo gupfuka inkweto zitagaragara zifite uburebure bwa mm 3 z'ubugari bwa EVA zitanga inkunga y'inkombe umunsi wose.

Inkweto z'abana: Imbere mu nda hafite imiterere ihamye kandi ijyanye n'ubushyuhe, ihura n'ibirenge by'abana bikura.

Ivugurura ry'Inganda: Uburyo Bushya bwo Gukora mu Ikoranabuhanga

Inganda zikora inkweto za EVA zirimo kuvugurura imikorere yazo:

Uburyo bwo gukanda bwa 4D:Ihindura ubucucike bw'uturere bushingiye ku makuru menshi y'urugendo, igabanya imikorere y'ibicuruzwa kugeza ku masegonda 90 kuri buri tsinda.

Ikoranabuhanga ryo gutobora imirasire ya laser:Igenzura neza uburyo imiterere y'ifuro ihumeka, ikagera ku bucucike bw'imiyoboro mito iri hagati ya 5.000–8.000 kuri cm².

Uburyo bwo gukurikirana blocchain:Ikurikirana imiterere ya karuboni mu buzima bwose, kuva ku bikoresho fatizo bikomoka ku binyabuzima kugeza ku bicuruzwa bishobora kongera gukoreshwa.

Ejo hazaza harambye: Ikintu cy'ingenzi gitera inkweto z'icyatsi kibisi

Ibigo bikomeye mu nganda byamaze gushyiraho uburyo bwo gucunga ubukungu bushingiye kuri EVA:

Umushinga wa Adidas wa Futurecraft.Loop wageze ku nkweto zo kwiruka za EVA zishobora kongera gukoreshwa 100%.

Gahunda ya Nike Grind ihindura EVA ikoreshwa mu bikoresho bya siporo, ikaba itunganya imyenda irenga miliyoni 30 buri mwaka.

Ikoranabuhanga rishya ryo gukuraho polymer mu binyabutabire rigera ku gipimo cyo kugarura monomer ya EVA cya 85%, rikuba gatatu agaciro ugereranije n’uko byari bisanzwe bikoreshwa mu kongera gukoresha ikoranabuhanga.
