He aha nā mea nui o ka resin UV

UV resinʻo ia ka mea nui o ka ʻōnaehana hoʻōla UV.He oligomer ia e hiki ke hoʻololi i ke kino a me ke kemika i ka manawa pōkole ma hope o ka ʻike ʻia ʻana i ke kukui UV, a me ka wikiwiki crosslink a ho'ōla.Ma hope o ka mālama ʻana i ka uhi ʻana o UV, ʻo ka hana maʻamau o ke kiʻi ʻoniʻoni e hilinaʻi nui ʻia i kāna mea hana kiʻiʻoniʻoni nui - UV resin, a me ka hana oUV resinua hoʻoholo ʻia e ka macromolecular polymer i hoʻokumu i kēia resin.ʻO ka molecular structure, molecular weight, double bond density and glass transition temperature of the polymer e hoʻopilikia i ka hana o ka resin.ʻO ka resin UV oily maʻamau he nui ka paona molekala a me ka viscosity, no laila he mau hemahema i ke kaʻina hana uhi a me ka mana hana kiʻiʻoniʻoni.AcrylateʻO ka mea hoʻoheheʻe ikaika [1] loaʻa nā mea paʻa pālua unsaturated a haʻahaʻa ka viscosity.ʻO ka hoʻohui ʻana iā ia i ka ʻōnaehana hoʻōla UV hiki ke hōʻemi i ka viscosity resin, hoʻomaikaʻi i ka hoʻopili cross-linking density o ka resin, a hoʻomaikaʻi i ka hana kiʻiʻoniʻoni o ka resin, no laila ua hoʻohana nui ʻia.Eia nō naʻe, ʻo ka hapa nui o nā mea hoʻoheheʻe ikaika he mea ʻawaʻawa a hoʻonāukiuki i ka ʻili kanaka, ka mucous membrane a me nā maka.Eia kekahi, paʻakikī ka diluent e pane piha i ka wā o ka UV irradiation, a ʻo ke koena monomer e hoʻopili pololei i ka hana lōʻihi o ke kiʻi curing, e kaupalena ana i kāna noi ʻana i nā mea hoʻopihapiha o nā huahana hoʻomaʻemaʻe meaʻai.

WaiwaiUV resinpili i kaUV resinhiki ke hoʻoheheʻe ʻia me ka wai.Aia i loko o kona mau mole ka nui o nā pūʻulu hydrophilic e like me carboxyl, hydroxyl, amino, ether or amide pūʻulu, a me nā hui unsaturated e like me acryloyl, methacryloyl a i ʻole nā ​​hui allyl.I kēia manawa, pili waiʻO nā resins UVʻO ka nui o ka polyacrylate wai, ka polyester acrylate, ka epoxy acrylate a me ka polyurethane acrylate.

Ma ke ʻano he ʻano polymer hou, ʻo ka polymer hyperbranched he ʻano spherical, he helu nui o nā pūʻulu hope hana, ʻaʻohe entanglement ma waena o nā kaulahao mole.Loaʻa i nā polymers Hyperbranched nā mea maikaʻi o ka hemo maʻalahi, kahi haʻahaʻa heheʻe, haʻahaʻa viscosity a me ka reactivity kiʻekiʻe.No laila, hiki ke hoʻokomo ʻia nā hui acryloyl a me nā pūʻulu hydrophilic e synthesize i nā oligomers UV curable waterborne, e wehe ana i kahi ala hou no ka hoʻomākaukau ʻana i ka wai.ʻO nā resins UV.
