Chiyambi cha Medical Hot Melt Adhesive

Medical hot melt adhesive ndi zomatira zomwe zimateteza chilengedwe zomwe zimapangidwa ndi zinthu za polima, zomwe zimagwiritsidwa ntchito polumikizira komanso kuyika zinthu zodzitchinjiriza zamankhwala monga masks azachipatala, mikanjo ya opaleshoni, ndi matumba oletsa kubereka. Zinthuzi, powonjezera zinthu zofunika kwambiri monga ufa wa chitsulo cha carbonyl ndi polyethylene glycol graft copolymer, zimapanga maukonde atatu-zowoneka bwino kwambiri kuti ziwongolere makina ake, zomwe zimakhala ndi luso la 16KN/m ndi mphamvu ya peel ya 180℃U{4}. Mapangidwe ake amagwirizana ndi miyezo yapadziko lonse ya FDA, alibe zosungunulira{{6}zopanda zosungunulira, ndipo adutsa potsimikizira kuwala kwa UV kuti apewe kukhala achikasu, kukwaniritsa zotchinga ndi zotchinga ndi kuyeretsa zopangira zida zachipatala. M'magwiritsidwe ntchito azachipatala, imakhala yabwino kwambiri yoletsa-kuchepetsa ndi kuletsa{9}}zoipa ndi khungu-yaubwenzi, kuthetsa vuto la kuchepa kwa zinthu zachikhalidwe pakuchita masewera olimbitsa thupi molimbika.

Medical hot melt adhesive imagwiritsa ntchito polystyrene-polyisoprene-polystyrene triblock copolymer (SIS) yolumikizidwa ndi polyethylene glycol (PEG) ngati maziko, ndikuwonjezera tetraethyl orthosilicate{2}}modified carbonyl iron powder kuti apititse patsogolo kufalikira. Mapangidwewa ali ndi 38% hydrogenated petroleum resin ndi 12% naphthenic mafuta, ndipo amayambitsa superabsorbent polima (SAP) utomoni kuti apange maukonde owongolera chinyezi.
