2-hydroxyethyl methacrylate(HEMA) he monomer polymerization organik i hana ʻia e ka hopena o ka ethylene oxide (EO) a me ka methacrylic acid (MMA), aia nā hui bifunctional i loko o ka mole.ʻO ka Hydroxyethyl methacrylate kahi ʻano wai kala ʻole, ʻākala, a maʻalahi ke kahe.Hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik maʻamau.Miscible me ka wai.

Noi o HEMA
1. Hoʻohana nui ʻia no ka hoʻololi ʻana i nā resins a me nā uhi.Hiki i ka Copolymerization me nā monomer acrylic ʻē aʻe ke hana i nā resins acrylic me nā pūʻulu hydroxyl ikaika i nā kaulahao ʻaoʻao, hiki ke hana i ka esterification a me ka crosslinking reactions, synthesize resins insoluble, hoʻomaikaʻi i ka adhesion, a hiki ke hoʻohana ʻia e like me nā mea lapaʻau fiber.Hoʻopili ia me ka melamine formaldehyde (a i ʻole urea formaldehyde) resin, epoxy resin, a me nā mea ʻē aʻe no ka hana ʻana i nā ʻāpana ʻelua.Hiki i ka hoʻohui ʻana i ka pena kaʻa kiʻekiʻe ke mālama i kona aniani aniani no ka manawa lōʻihi.Hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻopili no nā textiles synthetic a me nā monomers polymer olakino.
2. Hoʻohana ʻia ka HEMA no ka hana ʻana i nā resins no ka uhi ʻana, nā ʻaʻahu kaʻa kaʻa a me nā primers, a me nā resins photopolymer, nā papa paʻi, nā inika, ka gel (nā lens hoʻopili) a me nā mea hoʻopili tinning, transmission electron microscopy (TEM) a me optical microscopy (LM) embedding reagents, oi aku no ka hydration samples o "sensitive antigen sites".E like me ka wai keʻokeʻo, paʻa, ʻoi aku ka lahilahi ma mua o ka wai, a maʻalahi ke komo ʻana ma mua o nā resin a i ʻole monomer.Hoʻohana kūikawā ʻia no ka hana ʻana i nā iwi, cartilage, a paʻakikī ke komo i nā ʻiʻo mea kanu.
3. Hoʻohana ʻia ka ʻoihana plastik e hana i nā resins acrylic i loaʻa nā hui hydroxyl ikaika.Hoʻohana ʻia ka ʻoihana hoʻopili me ka epoxy resins, diisocyanates, melamine formaldehyde resins, etc.Hoʻohana ʻia ka ʻoihana ʻaila i mea hoʻohui no ka holoi ʻana i ka aila.Hoʻohana ʻia ka ʻoihana uila ma ke ʻano he mea hoʻoheheʻe wai no nā microscopes electron.Hoʻohana ʻia nā mea hoʻopili i ka ʻoihana textile e hana i nā lole.Hoʻohana ʻia ma ke ʻano he reagent kemika ma ke kemika analytical.Eia kekahi, hoʻohana ʻia ʻo ia ma ke ʻano he mea hoʻoheheʻe wai-soluble no ka synthesizing i nā mea polymer medical, thermosetting coatings, a me nā adhesives.
E hiki mai ana oHEMA:
Ua ʻōlelo ka poʻe loiloi ʻoihana ma muli o kāna hana hoʻokō maikaʻi loa, hydroxyethyl methacrylate i kēia manawa he koi kiʻekiʻe no nā noi, ʻoi aku hoʻi ma nā ʻano o nā lāʻau lapaʻau a me nā ʻāpana kiʻekiʻe, me nā manaʻo hoʻohiki.Aia nō nā manawa hoʻomohala i ka mākeke e hiki mai ana o hydroxyethyl methacrylate. Ma ka ʻaoʻao koi: Me ka ulu wikiwiki o ka noi ma nā māla e like me nā uhi a me nā mea hoʻopili, ke hoʻonui mau nei ka hoʻohana ʻana o 2-hydroxyethyl methacrylate. Ma ke ʻano loea,HEMAʻenehana hana a me ka ʻenehana hana polyether hiki ke aʻo mai kekahi i kekahi e pili ana i ka hoʻolālā, nā mea hana, ka hana, a me ka hana. a me nā mea hoʻoheheʻe wai i lalo.Ma ka manawa like, hydroxyethyl methacrylate he mea waiwai nui ia no ka ʻoihana o ka ʻili, e hōʻoia ana i ka hoʻolako ʻana i nā monomer kī no ka ʻoihana o lalo, e hoʻonui ana i ke kaulahao ʻoihana, a me ka hoʻonui hou ʻana i ka waiwai. .I mea e hoʻohui ai i kāna māhele mākeke, ua hoʻoholo ka hui e hoʻonui i kāna mau mea hana pono hana a hoʻomaʻemaʻe hou i ka wai ʻōpala kaʻina hana mua e hoʻonui ai i kāna hana ponoʻī.
