Intshayelelo kwi-Polyamide Hot Melt Adhesives

I-Polyamide eshushu encamathelayo enyibilikayo, ekwabizwa ngokuba yi-dimer acid polyamide hot melt adhesive, yimathiriyeli yepolymer eyenziwe ngeediacids kunye nediamines ngokusabela kwe-copolymerization, emva koko kusetyenzwe ngokuguqulwa kunye nokucolwa. Ukulungiswa kwayo kusekelwe kwiqondo eliphezulu{1}}lobushushu obuphezulu be-dimer acids kunye ne-polyamines, kwaye yahlulwe yangamacandelo amabini: ubunzima obuphezulu bemolekyuli (ukuhamba kakuhle, ukuchasana nokucoca okomileyo) kunye nobunzima obuphantsi bemolekyuli (amandla kunye nokuqina okungaphezulu kwe-EVA). Isetyenziswa kakhulu ekudibaneni amalaphu, ngethwathwa, isinyithi, kunye neeseramikhi, kwakunye nokukhuselwa amacandelo elektroniki kunye bookbinding.

Esi sixhobo sinendawo yokuthambisa yoluhlu lwe-100 ukuya ngaphezulu kwe-200 degree, ukunyamezela kweqondo lokushisa - kwe-40℃ukuya kwi-200 degree, kunye nobunzima obuthile obumalunga ne-0.97 kwiqondo lokushisa. Umbala wayo osisiseko yi-amber, enokuthi ilungelelaniswe kumbala omnyama, omhlophe, okanye eminye imibala ngokufaka i-carbon emnyama, i-titanium dioxide, njl. Kufuneka isetyenziswe ngokubambisana nomatshini wokubambelela obushushu onyibilikayo, kwaye izixhobo kufuneka zihlambuluke rhoqo ukukhusela i-carbonization ephezulu yokushisa kunye nokuvala.
