Enyanjula Ku Medical Hot Melt Adhesive

Medical hot melt adhesive ye adhesive etali ya bulabe eri obutonde bw’ensi okusinga ekoleddwa mu bintu bya polymer, okusinga ekozesebwa okusiba n’okusiba ebintu ebikuuma eby’obujjanjabi nga masiki z’obujjanjabi, gomesi z’okulongoosa, n’ensawo z’okuzaala. Ekintu kino, nga kwongerako ebitundu ebikulu nga butto w’ekyuma kya kaboni akyusiddwa ne polyethylene glycol graft copolymer, kikola ensengekera y’omukutu ey’ebitundu bisatu-okutumbula eby’obutonde, nga kirina engeri ey’ekikugu eya 16KN/m n’amaanyi g’ebikuta aga diguli 180 U-shaped. Enteekateeka yaayo ey’okukola etuukana n’omutindo gwa FDA ogw’ensi yonna, terimu solvent-, era eyise mu kukakasa obusannyalazo bwa UV okwewala okufuuka emmyufu, okutuukiriza ebiziyiza obuwuka obutonotono n’ebyetaago by’ebikuta ebiyonjo eby’okupakinga ebyuma eby’obujjanjabi. Mu nkola z’obujjanjabi, eraga eby’obugagga ebirungi ennyo ebiziyiza-okufuumuuka n’okuziyiza-okucaafuwaza n’omukwano gw’olususu-, okugonjoola ekizibu ky’okufiirwa okunywerera mu bintu eby’ekinnansi mu kiseera ky’okukola dduyiro ow’amaanyi.

Ekyesiiga eky’obusawo ekisaanuusa mu bbugumu kikozesa polystyrene-polyisoprene-polystyrene triblock copolymer (SIS) esimbye ne polyethylene glycol (PEG) ng’ekintu ekisookerwako, era kyongerako tetraethyl orthosilicate-modified carbonyl iron powder okulongoosa okutebenkera kw’okusaasaana. Ekirungo kino kirimu 38% hydrogenated petroleum resin ne 12% naphthenic oil, era kiyingiza superabsorbent polymer (SAP) resin okukola omukutu ogufuga obunnyogovu.
