Ke kālele nei kēia pepa i nā ʻāpana ʻelua solvent-free laminating adhesives, e kūkākūkā ana i ka hoʻopaʻa ʻana i ka waiwai o nā huahana solvent-free.
1. Ka Mana'o Kumu o ka Waiwai Papa
ʻO ka waiwai o ka pae ʻana ka hiki ke hoʻopaʻa ʻia i ka pae like a me ka maʻalahi ma ka ʻili o nā substrate.
2. Nā pilina a me nā hopena o ka pae ʻana ma nā pae like ʻole
Ma ke kūkākūkā aʻe nei, nā mea o ka hana paʻamau i ka mea like, me ka uhi ʻana i ke kaumaha, ka mahana, ke kaomi, a me nā mea ʻē aʻe.
No ka mea, ʻaʻohe mea hoʻoheheʻe ʻole ka mea hoʻoheheʻe ʻole i ke kumu, ʻo ka waiwai hoʻohālikelike ka hana o ka adhesive nona ponoʻī.ʻO ka pili ʻana, e ʻoi aku ka maʻemaʻe, akā ʻo ka solvent-free adhesive nō kona mau ʻano ponoʻī.
ʻO ka mea mua, pili loa ka waiwai o ka SF adhesive me ka viscosity o ka adhesive pono'ī.ʻOiai pili pololei ka viscosity me ka mahana a ʻokoʻa ke ʻano, ʻo ia hoʻi, e emi ana ka viscosity o SF adhesive ke piʻi ka mahana.A laila ma lalo o ka lumi wela, ʻokoʻa nui nā viscosities o nā SF adhesives e like me nā ʻano hoʻohālike SF adhesive a me nā waiwai kino.Eia naʻe, ma lalo o ka mahana hana kūpono o hoʻokahi kumu hoʻohālike SF, ʻaʻole maopopo loa ka ʻokoʻa o kona viscosity.No laila, ʻaʻole ʻoi aku ka maikaʻi o ka huahana viscosity haʻahaʻa i ka hoʻohālikelike ʻana i hoʻokahi kumu hoʻohālike SF viscosity kiʻekiʻe me kahi viscosity haʻahaʻa.No ka laʻana, WD8262A/B o KANGDA NEW MATERIALS, ma lalo o kona wela hana (ma kahi o 45 ℃), kona viscosity he 1100 mpa.s.Akā i ka laminating PET.INK/ALU, hiki iā ia ke hoʻokō i nā hiʻohiʻona maikaʻi me nā kiko ʻole i ka wā lamination mua.ʻO ka hopena, ʻaʻole ia he manaʻo hiki i ka viscosity haʻahaʻa ke lawe mai i kahi hiʻohiʻona maikaʻi.ʻO ka hoʻololi ikaika o SF adhesives kahi manawa wikiwiki, pono i nā mea he nui e hiki ai i kahi hopena maikaʻi.I kēia manawa, ʻoi aku ka haʻahaʻa o ka viscosity.No ka laʻana, ma lalo o 80-90 ℃ (Duble component SF adhesive), liʻiliʻi nā loli o ka viscosity me ka piʻi ʻana o ka mahana.
ʻO ka pae frist ka hoʻomau kino o ke kūlana adhesive i hui ʻia.Ma hope o ke kaʻina ʻana o ka uhi ʻana, hoʻemi ʻia kona waiwai pae me ka wikiwiki o ka hopena ma waena o nā mea A&B a me ka hāʻule ʻana o ka mahana.ʻO ka maʻamau, ʻike ʻia ka pae mua ʻana o ka SF adhesive e like me ka pae ʻana ma hope o ka laminating winding.I kēia manawa, ʻoi aku ka nui o ka viscosity o ka adhesive ma mua o ka hoʻopili ʻia ʻana ma nā wili ana.
ʻO ka hoʻohalikelike ʻana o ka mea hoʻopili maka, ʻo ia ka mea e hoʻohālikelike ai i ka waiwai o ka mea hoʻopili i loko o nā pahu ma mua o ka hui ʻana.ʻAʻole komo kēia waiwai hoʻohālikelike i ke kaʻina hana o ka laminating o nā kiʻiʻoniʻoni a i ʻole nā foil.
ʻO ka waiwai hoʻohālikelike ʻelua, ʻo ia, ma hope o ke kaʻina hana laminating a i ke kahua hoʻōla, hele ka SF adhesive i ke kahua o ka hoʻololi ʻana i ke keʻa wikiwiki ma lalo o ka mana o ka mahana, a ke emi nei ka hana leveling i ka nalowale loa.
3. Ka hopena
Ka waiwai hoʻopaʻa ʻana o ka mea hoʻopili SF maka ma mua o ka hui ʻia > ka waiwai hoʻopaʻa lua > ka waiwai hoʻopaʻa ʻana o ka mea hoʻopili SF i hui ʻia ma luna o nā lola ana > ka waiwai hoʻohālikelike mua.No laila, ʻo ke ʻano o ka hoʻololi viscosity o nā mea hoʻopili SF ʻoiaʻiʻo ke ala e piʻi aʻe nei, ʻokoʻa loa ia mai nā SB adhesives.
Inā he nīnau kāu e pili ana i ka laminating SF no ka hoʻopili maʻalahi, ua mākaukau mākou e kōkua iā ʻoe.
