Kushandiswa kweEVA hot melt adhesive

Munyika yangu, EVA hot melt adhesives anoshandiswa pakusunga anowanzo kupatsanurwa kuita-zvinomhanya uye zvakaderera-zvinonamira zvinomhanya. -zvinonamira zvinokurumidza kurapa nekukasira zvishoma, ukuwo zvinonamira zvakaderera{4}}zvinorapa zvishoma. Zvichienderana ne substrate iri kusungirirwa, anozoiswazve muzvikamu zvekunamira pabepa rekubvisa, bepa rakavharwa, nezvimwewo, uye kune zvinonamira kumashure uye zvinonamira padivi kuti zvienderane nekusimba uye zvinodiwa zvemidziyo iri kusungwa, nokudaro kuwana yakanaka yekubatanidza mhedzisiro. Kuziva magadzirirwo e{8}}ekare ekushandisa kwezvinonamira zvinonyunguduka zvinopisa zvakakosha, zvakaita sepre-kusunga bhandi uye tembiricha.

1. Preheating of EVA Hot Melt Adhesive Usati washandisa EVA inopisa yakanyunguduka adhesive, iyo yakasimba yakanamatira inofanira kutanga yave yakatsva uye yakanyungudutswa. Pane nzira mbiri dzekupisa: imwe yemafuta ekugezesa preheating, kureva, bhachi yakanyunguduka poto preheating; imwe yacho ielectric plate preheating, kureva, preheating yakananga uchishandisa electric heat plate mudziyo mupoto inonyunguduka. Iyo preheating nguva inowanzoita maawa maviri. Kamwe iyo yekunamatira inosvika kune inodiwa kupisa tembiricha uye ine yakanaka fluidity, inoonekwa seyakafanopisa zvinobudirira. Zvadaro, chinonamira chinoburitswa kuburikidza nepiipi yekushisa inogara ichienda mupoto inoshanda yekunamira patembiricha ye160-200℃yegluing uye kusunga mabhuku, zvinyorwa, nezvimwe.

2. Kubata uye Kukodzera kweEVA Kupisa Melt Adhesive Mukugadzirwa chaiko, kusungirirwa kwekunamatira kunopisa kunyunguduka kunosiyana zvichienderana nezvinhu zvakadai sekupisa kwekushisa kwekunamatira kunopisa kunopisa, zvinhu zvakasiyana-siyana uye hutano hwazvo, hupamhi nekudzika kwechigayo kumashure, kureba kwekunamatira kushandiswa, uye kukurumidza kwekushanda kwemushini wakakwana unosunga.
