Ibibazo by’ibidukikije birimo kwiyongera cyane mu iterambere ry’ubukungu, kandi kugera ku buhanga bw’ibidukikije ni igikorwa cyihutirwa muri iki gihe.
Ikoranabuhanga rya Supercritical foam ni ikoranabuhanga rishya rigezweho, ibikoresho bitanga ifuro bikoreshwa mu ikoranabuhanga rya supercritical foam akenshi ni supercritical carbon dioxide (ScCO2).2) na azote idasanzwe (ScN)2), byombi bikoreshwa nta mbogamizi ku bidukikije.
Mu bijyanye n'inkweto, Supercritical Foam Technology irimo guhindura urwego rw'inkweto. Iri koranabuhanga ryafashije abakora inkweto kwagura ubwoko bwazo bw'ibikoresho uretse TPU, TPE, na EVA bisanzwe. Ubu, bashobora no gukoresha ibikoresho nka PEBAX, ETPU, n'izindi elastomer kugira ngo bakore inkweto zifite umusego mwiza kandi zishyigikiwe, mu gihe zoroshye, ziramba, ziryoshye kandi zitangiza ibidukikije.
Ariko hakoreshejwe ikoranabuhanga rigezweho ryo gukora ifuro rya EVA, byahinduye uburyo inganda nyinshi zikoresha ibi bikoresho. Iri koranabuhanga rikoresha umuvuduko mwinshi n'ubushyuhe bwinshi kugira ngo rikore ifuro ryoroheje, riramba, kandi ridashobora kwangirika. Iyi gahunda ikubiyemo gutera umwuka, nka dioxyde de carbone (ScCO2).2), mu gisubizo cy'amazi cya EVA resin n'ibindi bivange. Hanyuma iyo gaze ishyushywa kandi igashyirwamo umuvuduko kugeza igeze ku rugero rwo hejuru cyane, bigatuma iyo gaze yaguka vuba kandi igakora uduheri duto. Utwo duheri duhita dufatirwa mu gisubizo cy'amazi, bigatuma habaho ifuro rifite imiterere myiza ugereranije n'ifuro gakondo. Ni ryihuse, ryoroshye, rikomeye, kandi riramba, bigatuma riba amahitamo meza ku bikorwa bitandukanye. Urugero, kuva ku nkweto itanga imitako n'inkunga ku birenge kugeza ku bikoresho by'isuku, ibikoresho by'imikino, imitako yo hasi/yoga, ibikinisho, ibipfunyika, ibikoresho by'ubuvuzi, ibikoresho byo kwirinda, ibikoresho bidatemba amazi, paneli za photovoltaic, n'ibindi byinshi... Ikoreshwa kandi mu bikoresho by'imodoka n'iby'indege kugira ngo itange ubushyuhe n'ubudahangarwa bw'amajwi.
Ikoranabuhanga rirambye ry'ibikoresho bishya rikozwe muri EVA foam!
Ariko, gukoresha ikoranabuhanga rya supercritical foam mu gukora ibikoresho bya EVA bisaba kwitabwaho ku kibazo cyo guhuza. Iminyururu ya molekile ya EVA ni umurongo ugororotse kandi isaba imiterere ifatanye kugira ngo ifunge iyo gaze. Nubwo isanzwe ikorwa mu nkweto no mu bindi bice, ntabwo ikoreshwa cyane. Ikibazo gikomeye cyo guhuza ifuro ni uko igipimo cy'umusaruro kirangiye kiri hasi cyane, kiri munsi ya 50%, bityo bikabangamira iterambere ry'imvange ivanze.
EVA yavanzwe n'ikoranabuhanga rya Si-TPV ryo kongera gukoresha EVA rihindura ifuro 100%, Iri koranabuhanga rya EVA rifasha gutwara inkweto mu cyerekezo cyiza kandi kirambye. Ntabwo rishobora gusa kugera ku bucucike buke no gukomera cyane ahubwo rinagira ubushobozi bwo kwangirika neza, rigabanya umuvuduko wo gushonga k'ubushyuhe, rifite ibara rimwe, rirangira neza, rikoresha byoroshye, kandi rihendutse, Gereranya n'ifuro rikabije.
Uko inganda nyinshi zitangiye gukoresha iyi Soft EVA Foam Modifier Si-TPV ivanze na ikoranabuhanga rya EVA, dushobora kwitega kubona uburyo bushya bwo gukoresha iyi mashini nshya. Ubushya ntibugarukira gusa ku nganda z'inkweto zoroshye cyane.
Niba ushaka Solutions za Flexible Soft EVA Foam material Solutions, Modifier igabanya gukanda kwa EVA foam, ikoranabuhanga rya Chemical foam kuri EVA foam yoroheje, Soft EVA Foam Modifier cyangwa Solutions kuri supercritical foam.
Twandikire, kugira ngo umenye byinshi.
