Ziyini izinzuzo ze-pur hot melt adhesive?

       Ama-meltadhesives ashisayounezinzuzo eziningi kune-EVA hot melt adhesives. Izimboni eziningi zisebenzisa kancane kancane okunamathiselwe kwe-pur hot melt adhesives ukufaka i-EVA hot melt adhesives. Njengemishini ekhethekile yokufafaza yokunamathisela kwe-pur hot melt adhesives, i-pur hot melt adhesiveshave nayo ithathelwe indawo. Kwamukelwe izimboni eziningi. Ngakho-ke yiziphi izinzuzo zokunamathisela okunamandla okuncibilikayo?

1. Uhlobo olungenasici kuphela. Ngokungafani nezinto zokunamathisela ezincibilikisayo ezidinga ukulinda inqubo yokoma, kungonga isikhathi, futhi ayikho i-solvent engeke ingcolise imvelo futhi ifake imvelo ubuthi. Inqubo yokubopha ilula futhi ingasetshenziswa nge-roller coating noma umlomo wokumboza nezinye izindlela zokulinganisa, elungele imishini ehlukahlukene yokuzilinganisa.

2. Ukunamathela kuthempelesha ephansi. Izinga lokushisa elincibilikayo lokunamathisela kwe-pur hot-melt kuncane kunokwejwayelekile kwe-EVA hot-melt adhesive (170-200℃). Ingasetshenziswa ekushiseni okuphansi futhi ingasetshenziswa ku-120-150℃, esindisa amandla futhi inciphise ukungasebenzi kahle kwensiza yokulinganisa. , Ilungele ikakhulukazi izinto zokubopha ukushisa (ezifana namapulasitiki, njll.).

3. Ukuphulukiswa okusheshayo.Izinto ezimbili ezinamathelayo zingalungiswa ngesikhathi esifushane (cishe amasekhondi ayi-6-20), futhi izingxenye zomhlangano zingadluliselwa ngokushesha kunqubo elandelayo yokucubungula ukwenza ngcono ukusebenza kahle komsebenzi.

4.Imvelo esebenzayo: impilo yebhodwe ingaba amahora afinyelela kwangu-16 ngo-150 ° C nezinsuku ezi-3 ngo-90 ° C. Futhi inokumelana nokushisa okuhle kakhulu, ukumelana okubandayo, ukumelana nomhwamuko wamanzi, ukumelana namakhemikhali kanye nokumelana ne-solvent.
