Chigadzirwa maitiro e polyamide inopisa melt adhesive
Siya meseji
Polyamide hot melt adhesive, inozivikanwawo se dimer acid polyamide hot melt adhesive, inogadzirwa nepamusoro-temperature condensation reaction ye dimer acid ne polyamine. Iyo ine yakanakisa kupisa kupisa, kutonhora kuramba, magetsi zvimiro, mafuta kuramba, makemikari kuramba, uye media kuramba; haina hwema uye haina ruvara; inorapa nokukurumidza; inogona kubatanidza simbi dzakasiyana ne-zvisiri; uye ine kuenderana kwakanaka nemamwe marezeni.
Chigadzirwa chacho chinogona kushandiswa kubatanidza machira, matehwe, matanda, mapurasitiki, simbi, ceramics, nezvimwe zvinhu, pamwe nekubatanidza nekudzivirira zvinhu zvemagetsi, kusungirira mabhuku, kuumba-kuumba majekiseni akaderera, uye kugadzira matepi.
High molecular uremu polyamide inopisa melt adhesive: yakanaka kuyerera, yakakwirira bonding simba, uye kuramba yakaoma kuchenesa uye kugeza; Yakaderera molecular uremu polyamide inopisa inonyungudutsa adhesive: yakanaka simba uye kuoma, ine zvivakwa zvakawanda zviri nani kune EVA inopisa inonyunguduka adhesive.
Kazhinji, nzvimbo yekunyorovesa yepolyamide inopisa inonyunguduka inonamatira inotangira pa100 dhigirii kusvika pamusoro pe200 dhigirii, inogona kutsungirira tembiricha yakaderera kusvika -40 dhigirii, uye tembiricha yepamusoro inosvika 200 degree. Patembiricha yekamuri, giravhiti rayo chairo rinowanzo 0.97.
Rudzi rwekutanga rwe polyamide inopisa inonyunguduka adhesive iamber (yellow), asi kazhinji inogona kuitwa dema nekuwedzera kabhoni dema, chena nekuwedzera titanium dioxide, uye mune dzimwe nyaya dzisina kujairika, mamwe pigment anogona kuwedzerwa kuishandura kuita mamwe mavara. Ruvara-kuchinja polyamide hot melt adhesives anowanzo shandiswa mune akakosha maapplication akaita sepasi-pressure injection molding.
