Intangamarara ya EVA Hot Melt Igifatanya

EVA ishushe ipfutse ni ikintu gishobora gusenyuka-kidafise, amazi-kidafise, 100% gikomeye, gishobora gusenyuka. Irakomeye mu bushuhe bwo mu cumba kandi irashonga ikagira ikintu gifatanya n’amazi gishobora gutemba kandi gikomeye iyo gishushe ku rugero runaka. Inyuma yo gushonga, ni ikintu c’inzobe yoroshe, gica ibibatsi canke kidafise -umweru. Igihimba nyamukuru c’ivyuma bifatanya ivyuma bishushe, ni ukuvuga ivyuma vy’ishimikiro, ni copolymer y’ivyuma bifatanya n’ibindi bihimba vy’umubiri bifise umuvuduko munini, bifatanijwe n’ibintu bifatanya, ivyuma bihindura uburemere bw’ibintu, ivyuma bifatanya n’ivyuma bishushe, n’ibindi, kugira ngo bibe ivyuma bifatanya ivyuma bishushe.

EVA ni ikintu c’ipulasitike gikozwe muri éthylène (E) na vinyl acetate (VA). Igitigiri c’ivyo bihimba bibiri bishobora guhindurwa kugira ngo bihure n’ivyo umuntu akeneye bitandukanye. Ivyo bihimba vy’umubiri bifise vinyl acetate (VA) vyinshi bituma umuntu abona neza, akagira uburyohe kandi akagira ubukomezi.

Igikoresho co gukorana n’ibindi bihimba vy’umubiri (kizwi kandi kw’izina rya etileni-ivy’umubiri) kironswa mu gukoranya etileni (E) n’ivyuma vy’umubiri (VA). Izina ryayo ry’icongereza ni Etilene Vini Acetate, rikaba rivugwa mu buryo bugufi ngo EVA canke E/VAC. Uburyo bwo gukora polymérisation burimwo gukora polymérisation y’umuvuduko munini - (ku mapulasitike), polymérisation y’umunyu (ibifasha mu gukora PVC), polymérisation y’umunyu (ibikoresho bifatanya), n’ugukora polymérisation y’umunyu. Ivyuma bikoreshwa mu gutera ivyatsi bikoreshwa ku birimwo vinyl acetate (VA) birenze 30%, mu gihe ivyatsi vyinshi vy’umuvuduko munini-bikoreshwa ku birimwo VA bike. EVA ifise ubuhinga bwinshi bwo gukoresha.

Muri rusangi, EVA ifise vinyl acetate iri munsi ya 5% ikoreshwa canecane mu gukora amafilime, mu guhindura LDPE mu gukora amawaya n’imirongo, no ku bikoresho bifatanya; EVA ifise vinyl acetate 5%-10% ikoreshwa mu gukora amafilime y’ivyuma; EVA ifise vinyl acetate 20%-28% ikoreshwa cane cane mu bikoresho vy’ugufatanya n’ibindi bikoresho vyo gupfuka; na EVA ifise vinyl acetate irimwo 5%-45% ikoreshwa cane cane mu mafilime (harimwo n’amafilime y’uburimyi) n’amashiti, ibintu bibumbwe n’ibibumbwe n’inshinge, ibintu bibumbwe n’ifu, n’ibintu bifatanya n’ibindi bishushe. Ikoreshwa cane mu bikoresho vy’inkweto bifise ifu, mu bipande vy’ivyatsi bikora neza, mu bikoresho vyo gupfunyika, mu bikoresho bifatanya ibintu bishushe, mu nsinga n’imirongo, no mu bikinisho.
