ʻAcrylate Hydroxyethyl
ʻIke Huahana
ʻO Hydroxyethyl Acrylate (HEA) kahi monomer monofunctional versatile a he poloka hale koʻikoʻi i ka kemika polymer. Hōʻike ia i kahi pilina pālua acrylic polymerizable a me kahi hui hydroxyl reactive i loko o ka mole like. ʻAe kēia ʻano hana iā ia e hana maʻalahi i ka copolymerization me kahi ākea o nā monomers ʻoiai e komo pū ana i nā hopena crosslinking. He wai moakaka, kala ʻole a melemele māmā a ʻike ʻia no ka hoʻonui nui ʻana i nā waiwai hana o nā huahana polymeric hope loa, ʻoiai ke hoʻohana ʻia i nā nui liʻiliʻi.

Nā Noi Nui
ʻO ka hana pālua o HEA e lilo ia i mea koʻikoʻi ma nā ʻoihana he nui:
Nā Uhi a me nā ʻīnika:
Nā Uhi Thermosetting: He monomer mua i nā uhi kaʻa, ʻoihana, a me nā mīkini. Hoʻopili ka hui hydroxyl me nā resins melamine-formaldehyde a i ʻole polyisocyanate (i loko o nā uhi PU), e hāʻawi ana i ka paʻakikī maikaʻi loa, ke kūpaʻa kemika, a me ke kūpaʻa mar.
Nā ʻōnaehana hoʻōla-Radiation: Hoʻohana ʻia ma ke ʻano he mea hoʻoheheʻe reactive a me ka crosslinker i nā uhi UV/EB-curable, nā ʻīnika, a me nā mea hoʻopili. He mea nui ia i ka synthesis o nā urethane acrylates.
Nā Photoresist a me nā Photoreactive Polymers: Hoʻohana ʻia i ka hana ʻana o nā resins photoresist no nā papa paʻi a me nā mea uila (semiconductors, LCDs).
Nā mea hoʻopili a me nā mea sila:
Hoʻomaikaʻi i ka ikaika o ka hoʻopili ʻana i nā ʻano substrates like ʻole, me nā metala a me nā plastics.
Hoʻonui i ka nui o ka crosslink, e alakaʻi ana i ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa kemika, a me ka ikaika paʻa i nā mea hoʻopili kūkulu a me ke kaomi (PSAs).
Nā lole a me nā olonā:
Hoʻohana ʻia ma ke ʻano he co-monomer i nā mea lapaʻau fiber a me nā uhi lole e hāʻawi i ke kūpaʻa wai, kūpaʻa wrinkle, a me ke kūpaʻa.
Ka Hana ʻana i ka Pepa:
Hoʻohui ʻia i loko o nā ʻano uhi e hoʻomaikaʻi i ka ikaika pulu a me ka maloʻo, ke kūpaʻa wai, a me ka hiki ke paʻi ʻia.
Nā Hoʻohana Kūikawā:
ʻOihana Lubricant: Hana ma ke ʻano he kemika waena no ka hana ʻana i nā mea hoʻohui detergent a me nā mea hoʻoheheʻe.
Nā mea uila: Hoʻohana ʻia ma ke ʻano he mea hoʻomaloʻo maloʻo i ka hoʻomākaukau ʻana i ka hāpana microscopy electron.
Kemika Loiloi: Hana ma ke ʻano he mea hoʻohui kemika a ma ke ʻano he ʻāpana i nā mea hoʻokomo e hui pū ʻia me ka wai.
Nā Hiʻohiʻona Koʻikoʻi a me nā Pōmaikaʻi
Hana Pālua: ʻO ka hui acrylate e hiki ai i ka copolymerization, ʻoiai ʻo ka hui hydroxyl e ʻae ai no ka crosslinking a me ka hoʻololi kemika.
Hana Hoʻonui: Hāʻawi i ke kūpaʻa kupaianaha, ke kūpaʻa kemika, a me ka hoʻopili ʻana i nā polymers hope loa.
Ke Hana Hou Kiʻekiʻe: Hoʻopili koke ʻia me nā acrylates, methacrylates, styrene, vinyl acetate, acrylonitrile, a me nā mea hou aku.
Versatility: Kūpono no nā kaʻina hana polymerization like ʻole, me ka hoʻonā, emulsion, a me ka polymerization suspension.
Ka Hana Kūpono: Hāʻawi i kahi hoʻomaikaʻi koʻikoʻi i nā waiwai o ka huahana ʻoiai ma nā pae hoʻohui haʻahaʻa (maʻamau 2-10%).
ʻO ka Viscosity Haʻahaʻa: Hana ma ke ʻano he mea hoʻoheheʻe reactive maikaʻi i nā ʻōnaehana hiki ke hoʻōla ʻia e ka radiation, e kōkua ana i ka hōʻemi ʻana i ka viscosity formulation me ka hoʻohana ʻole ʻana i nā hui organik volatile (VOCs).
Ka lawelawe ʻana a me ka mālama ʻana
Mahana Mālama: E mālama i kahi wahi anu a maikaʻi ka ea. ʻO ka mahana mālama i ʻōlelo ʻia ma waena o 2°C a me 25°C (36°F a me 77°F). E pale i ka hau a me nā mahana kiʻekiʻe.
Mea Hoʻopaʻa: Loaʻa ka mea hoʻopaʻa MEHQ e pale i ka polymerization spontaneous. Pono ka mea hoʻopaʻa i ke alo o ka oxygen e hana; no laila, ʻo ka mālama ʻana ma lalo o kahi lewa inert (e laʻa me ka Nitrogen padding) he mea nui ia no ke kūpaʻa lōʻihi.
Pahu: E mālama i loko o nā pahu i hoʻopaʻa paʻa ʻia i hana ʻia me ke kila kila, ke kila i uhi ʻia me ka resin phenolic, a i ʻole polyethylene. E pale mai ka mālamalama.
Ola Papa: ʻO ka maʻamau he 6 a 12 mau mahina mai ka lā i hana ʻia ai ke mālama ʻia ma lalo o nā kūlana i ʻōlelo ʻia.
Ka lawelawe ʻana: E hoʻohana me ka ea kūpono a me nā kaohi ʻenekinia. E pale i ka pili ʻana me ka ʻili, nā maka, a me nā lole. E ʻaʻahu i nā lako palekana pilikino (PPE) kūpono, me nā mīkina lima pale kemika, nā maka aniani palekana, a me nā lole pale.
