Hoʻohana ʻia nā Oligomers i ka ʻoihana UV Ink

ʻO nā oligomers nā molekole i loaʻa i kekahi mau ʻāpana hana hou, a ʻo lākou nā mea nui o nā inks curable UV.ʻO nā ʻīnika hiki ke hoʻōla ʻia o UV he mau inika hiki ke hoʻomaloʻo ʻia a hoʻōla koke ʻia e ka ʻike ʻana i ke kukui ultraviolet (UV), i mea kūpono no ka paʻi kiʻekiʻe a me nā kaʻina hana uhi.He kuleana koʻikoʻi ka Oligomers i ka hoʻoholo ʻana i nā waiwai a me ka hana o nā inika hoʻōla UV, e like me ka viscosity, adhesion, flexibility, durability, and color.

ʻEkolu mau papa nui o nā oligomers UV curable, ʻo ia hoʻi nā epoxy acrylates, polyester acrylates, a me ka urethane acrylates.Loaʻa i kēlā me kēia papa kona mau hiʻohiʻona ponoʻī a me nā noi, ma muli o ke ʻano o ka substrate, ke ʻano hoʻōla, a me ka maikaʻi i makemake ʻia o ka huahana hope.

ʻO nā acrylate epoxy he oligomers i loaʻa nā pūʻulu epoxy ma ko lākou iwi kua, a me nā hui acrylate ma ko lākou mau wēlau.ʻIke ʻia lākou no ko lākou reactivity kiʻekiʻe, haʻahaʻa viscosity, a me ke kūpaʻa kemika maikaʻi.Eia nō naʻe, loaʻa iā lākou kekahi mau drawbacks, e like me ka hiki ʻole o ka maʻalahi, ka haʻahaʻa haʻahaʻa, a me ke ʻano melemele.He kūpono nā epoxy acrylates no ka paʻi ʻana ma luna o nā substrate paʻa, e like me ke metala, aniani, a me ka plastic, a no nā noi e koi ana i ka nani a me ka paʻakikī.

ʻO nā acrylates polyester he oligomers i loaʻa nā pūʻulu polyester ma ko lākou iwi kua, a me nā hui acrylate ma ko lākou mau wēlau.Ua ʻike ʻia lākou no ko lākou ʻano haʻahaʻa haʻahaʻa, haʻahaʻa haʻahaʻa, a me ka loli maikaʻi.Eia nō naʻe, loaʻa iā lākou kekahi mau drawbacks, e like me ke kiʻekiʻe viscosity, haʻahaʻa haʻahaʻa kemika, a me ka hoʻokuʻu ʻana.He kūpono nā polyester acrylates no ka paʻi ʻana ma luna o nā substrate maʻalahi, e like me ka pepa, kiʻiʻoniʻoni, a me ka lole, a no nā noi e pono ai ke adhesion maikaʻi a me ka elasticity.

ʻO Urethane acrylates nā oligomers i loaʻa nā pūʻulu urethane ma ko lākou iwi kua, a me nā hui acrylate ma ko lākou mau wēlau.Ua ʻike ʻia lākou no kā lākou haʻahaʻa haʻahaʻa, viscosity kiʻekiʻe, a me ka loli maikaʻi.Eia nō naʻe, loaʻa iā lākou kekahi mau drawbacks, e like me ke kumukūʻai kiʻekiʻe, ka pale ʻana i ka oxygen kiʻekiʻe, a me ka wikiwiki hoʻōla haʻahaʻa.He kūpono nā Urethane acrylates no ka paʻi ʻana ma luna o nā substrate like ʻole, e like me ka lāʻau, ka ʻili, a me ka lāʻau, a no nā noi e koi ai i ka lōʻihi kiʻekiʻe a me ke kūpaʻa abrasion.

I ka hopena, he mea nui ka oligomers no ka hoʻokumu ʻana a me ka hana ʻana o nā inika hoʻōla UV, a hiki ke hoʻokaʻawale ʻia i ʻekolu mau papa nui, ʻo ia ka epoxy acrylates, polyester acrylates, a me ka urethane acrylates.Loaʻa i kēlā me kēia papa kona pono ponoʻī a me nā hemahema, e pili ana i ka noi a me ka substrate.ʻO ka hoʻomohala ʻana i nā oligomers a me ka inika UV he kaʻina hana mau, a ke ʻimi ʻia nei nā ʻano oligomers hou a me nā ʻano hoʻōla e hoʻokō i nā koi nui o ka ʻoihana inika.
