Ukusetyenziswa kwe-adhesive ye-EVA eshushu enyibilikayo

Kwilizwe lam, izinto zokuncamathelisa ze-EVA ezishushu ezinyibilikayo ezisetyenziselwa ukuqhina zohlulwa ngokubanzi-zesantya kunye nezisezantsi{1}}zincamathelisi zesantya. Isantya esiphezulu-izinto zokuncamathelisa zinyanga ngokukhawuleza kancinci, ngelixa izinto ezincamathelayo ezisezantsi{4}}zinyangeka kancinane. Ngokuxhomekeke kwi-substrate edibeneyo, iphinda ihlelwe kwi-adhesives ye-offset paper, i-coated paper, njl. Ukuqonda kwangaphambili{8}}usetyenziso lweenkqubo zokuncamathelisa inyibilika eshushu kubalulekile, ezifana{9}}ngaphambili nolawulo lobushushu.

1. Ukushisa kwangaphambili kwe-EVA ye-Hot Melt Adhesive Ngaphambi kokusebenzisa i-adhesive ye-EVA eshushu enyibilikayo, i-adhesive eqinile kufuneka iqale ishushu kwaye inyibilike. Kukho iindlela ezimbini zokufudumeza kwangaphambili: enye yibhafu ye-oyile yokufudumeza kwangaphambili, oko kukuthi, ukufudumeza kwembiza enebhatyi; enye ipleyiti yombane preheating, oko kukuthi, preheating ngqo usebenzisa isixhobo ipleyiti yokufudumeza yombane kwi imbiza preheating ukunyibilika. Ixesha lokufudumeza ngokuqhelekileyo ziiyure ezi-2. Nje ukuba i-adhesive ifikelele kwiqondo lokushisa elifunekayo lokufudumeza kwaye ine-fluidity enhle, ithathwa njenge-preheated ngempumelelo. Emva koko, i-adhesive ikhutshwe ngombhobho wokushisa oqhubekayo kwi-adhesive pot esebenzayo kwiqondo lokushisa le-160-200℃ye-gluing kunye nokubopha iincwadi, iincwadana, njl.

2. Ukubambelela kunye nokufaneleka kwe-EVA Hot Melt Adhesive Kwimveliso yangempela, ukunamathela kwe-adhesive eshushu enyibilikayo kuyahluka ngokuxhomekeke kwizinto ezifana nobushushu bokufudumala kwe-adhesive eshushu enyibilikayo, izinto ezahlukeneyo kunye nomgangatho wazo, ububanzi kunye nobunzulu be-milling back, ukuphakama kwesicelo sokubambelela, kunye nesantya sokusebenza somatshini wokubopha ogqibeleleyo.
