Akwụkwọ a na-elekwasị anya n'akụkụ abụọ nke ihe mgbaze na-enweghị laminating adhesives, na-atụle nhazi ọkwa nke ngwaahịa na-enweghị ihe mgbaze.
1. Ihe bụ isi pụtara nke imezi ihe onwunwe
Nkwalite ihe onwunwe bụ ikike nke mkpuchi iji mee ka ọ dị larịị na nke ọma n'elu ihe ndị ahụ.
2. Mmekọrịta na mmetụta nke ọkwa ọkwa na ọkwa dị iche iche
Na ndị na-esonụ mkparịta ụka, ọcha nke emeputa ndabara ka otu, gụnyere mkpuchi arọ, okpomọkụ, nrụgide, wdg N'ihi na ihe niile ga-eme ka mgbanwe ikpeazụ laminates, anyị ga-ahụ ndị a variables dị ka ofu.
N'ihi na nrapado na-enweghị ihe mgbaze enweghị ihe mgbaze ka ọ bụrụ ihe ndabere, ihe nhazi ọkwa bụ arụmọrụ nke nrapado nke ya.N'ikwu okwu, ọ ga-adị ọcha, mana nrapado na-enweghị ihe mgbaze ka nwere njirimara nke ya.
Nke mbu, ikwado ihe nke SF adhesive nwere njikọ chiri anya na viscosity nke nrapado n'onwe ya.Ọ bụ ezie na viscosity nwere njikọ kpọmkwem na ọnọdụ okpomọkụ ma na-agbanwe agbanwe, nke pụtara viscosity nke nrapado SF ga-ebelata mgbe okpomọkụ na-abawanye.Mgbe ahụ n'okpuru ọnọdụ okpomọkụ, viscosities nke raw SF adhesives nwere nnukwu ọdịiche dị ka ụdị nrapado SF dị iche iche na ihe anụ ahụ.Agbanyeghị, n'okpuru ọnọdụ okpomọkụ kwesịrị ekwesị nke otu ụdị nrapado SF, ọdịiche dị na viscosity ya apụtaghị nke ọma.Ya mere, ngwaahịa viscosity dị ala nwere ike ọ bụghị nke ka mma mgbe ị na-atụnyere otu akwa viscosity SF adhesive model na obere viscosity.Dịka ọmụmaatụ, WD8262A/B nke KANGDA NEW MATERIALS, n'okpuru ọnọdụ okpomọkụ ya (ihe dị ka 45 ℃), viscosity ya bụ 1100 mpa.s.Ma mgbe ị na-agbanye PET.INK/ALU, ọ nwere ike nweta ọdịdị dị mma na-enweghị ntụpọ n'oge mbụ lamination.Dị ka nkwubi okwu, ọ pụtaghị na viscosity dị ala nwere ike iweta ọdịdị dị mma.Mgbanwe mgbanwe nke SF adhesives bụ oge ngwa ngwa, nke chọrọ ọtụtụ ihe iji nweta mmetụta dị mma.Ka ọ dị ugbu a, viscosity nwere ala kacha ala.Ka ihe atụ, n'okpuru 80-90 ℃ (Double akụrụngwa SF nrapado), viscosity nwere obere mgbanwe na-ebili okpomọkụ.
Nkwanye frist bụ ịga n'ihu n'anụ ahụ nke ọkwa nrapado agwakọta.Mgbe usoro mkpuchi gasịrị, ihe nrịbawanye ya na-ebelata n'ihu yana mmeghachi omume ngwa ngwa n'etiti ihe A&B na mbelata okpomọkụ.N'ozuzu, a na-ahụta ọkwa nke mbụ nke nrapado SF dị ka ọkwa ọkwa mgbe ikuku na-agbaze.N'oge a viscosity nke nrapado ga-aka nke ukwuu karịa agwakọta nrapado na metering rollers.
Ịkwado ihe nrapado dị ndụ pụtara nhazi ọkwa nke nrapado n'ime ịgbà tupu agwakọta ya.Ngwongwo a na-eme ka ọ dị larịị adịghị esonye na nhazi nke ihe nkiri ma ọ bụ foils.
Ngwongwo ọkwa nke abụọ bụ na, mgbe usoro laminating na n'ime usoro ọgwụgwọ, nrapado SF na-abanye n'ọkwa nke mmeghachi omume njikọ ngwa ngwa n'okpuru mmetụta nke okpomọkụ, na nhazi ọkwa na-ebelata ka ọ pụọ kpamkpam.
3. Nkwubi okwu
Ngosipụta ihe nke raw SF adhesive tupu agwakọta> ihe dị larịị nke abụọ> ihe dị larịị nke nrapado SF agwakọtara na igwe igwe igwe> ihe na-ebu ụzọ.Ya mere, mgbanwe mgbanwe viscosity nke SF adhesives n'ezie bụ usoro na-arị elu, nke doro anya na ọ dị iche na adhesives SB.
Ọ bụrụ na ị nwere ajụjụ ọ bụla gbasara SF laminating maka nkwakọ ngwaahịa na-agbanwe agbanwe, anyị dị njikere inyere gị aka.
