ʻAkrilate Hydroxypropyl
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 Hana Nui o Hydroxypropyl Acrylate
ʻO ka hana pālua o HPA e hiki ai ke hoʻohana ʻia ma nā ʻoihana like ʻole. ʻO kāna hana nui ka hana ma ke ʻano he mea hoʻoheheʻe reactive a me kahi mea hoʻolako pūnaewele crosslinking.
Nā Uhi a me nā ʻīnika:
Nā Uhi Thermosetting: Hana ma ke ʻano he co-monomer i nā uhi kaʻa, ʻoihana, a me nā coil. Hoʻopili ia me ka melamine, isocyanate, a i ʻole epoxy resins, e hopena ana i nā kiʻiʻoniʻoni me ka paʻakikī maikaʻi loa, ke kūpaʻa kemika, ke kūpaʻa mar, a me ka ʻōlinolino kiʻekiʻe.
Nā ʻōnaehana hoʻōla-Radiation: Hoʻohana ʻia i nā uhi UV/EB-curable, nā ʻīnika, a me nā mea hoʻopili. ʻAe ka hui hydroxyl i ka hana ʻana o nā urethane acrylates me nā waiwai i hoʻonui ʻia.
Nā Resins Photoresist: He ʻāpana koʻikoʻi i nā resins photo-sensitive no ka hana semiconductor a me ka hōʻike.
Nā mea hoʻopili a me nā mea sila:
Hoʻomaikaʻi i ka hoʻopili ʻana i nā mea paʻakikī ke hoʻopaʻa e like me nā metala a me nā plastik i mālama ʻia.
Hoʻonui i ka nui o ka crosslink, e alakaʻi ana i ka hoʻomaikaʻi ʻana i ke kūpaʻa wela, ke kūpaʻa kemika, a me ka ikaika paʻa i nā mea hoʻopili koʻikoʻi (PSAs) a me nā mea hoʻopili kūkulu.
Nā lole a me nā olonā:
Hoʻohana ʻia ma ke ʻano he mea lapaʻau fiber e hoʻololi i nā fiber synthetic, hoʻomaikaʻi i ka dyeability, nā waiwai antistatic, a me ka omo ʻana o ka makū.
Nā Resins Synthetic & Plastics:
Ma ke ʻano he mea hoʻololi no ka acrylic a me nā resins synthetic ʻē aʻe, hāʻawi ʻo Hydroxypropyl acrylate i ke kūpaʻa maikaʻi loa i ka wā, ke kūpaʻa i ka hopena, a me ka maʻalahi.
ʻO Hydroxypropyl Acrylate Nā Hana ʻē aʻe:
Ka Hana ʻana i ka Pepa: Ma ke ʻano he resin ikaika a me ka ʻāpana uhi.
Nā Kemika Hoʻōla Wai: Hoʻohana ʻia i ka hana ʻana o nā mea pale unahi a me ka palaho.
Nā Mea Hoʻohui Lubricant: Hana ma ke ʻano he mea hoʻomākaukau no nā mea hoʻomaikaʻi i ka index viscosity a me nā mea hoʻolaha.
Nā Hiʻohiʻona Koʻikoʻi a me nā Pōmaikaʻi o Hydroxypropyl Acrylate
Ka Hana Kūpono Loa: Hoʻopili maʻalahi ka hui acrylate me nā ʻano monomers vinyl a me acrylic (e laʻa, methyl methacrylate, butyl acrylate, styrene, acrylonitrile).
Ka Mana Hoʻohuihui Ikaika: Hoʻopili maʻalahi ka hui hydroxyl pendant me nā diisocyanates, anhydrides, a me nā resins amino (e laʻa, melamine), e hiki ai ke hoʻokumu ʻia nā pūnaewele polymer ʻekolu-dimensional paʻa.
Hoʻopili Hoʻonui: Paipai i ka hoʻopili ikaika ʻana i nā substrates like ʻole.
Hoʻomaikaʻi i ke kūpaʻa: Hāʻawi i ke kūpaʻa koʻikoʻi i nā kemika, nā mea hoʻoheheʻe, ka ʻino, a me ke kukui UV.
Versatility: Hiki ke hoʻohana ʻia i loko o nā ʻano hana polymerization he nui, me ka hoʻonā, emulsion, suspension, a me ka polymerization bulk.
Ka Hana Kūpono: Hāʻawi i nā hoʻomaikaʻi koʻikoʻi i nā waiwai o ka huahana hope loa ʻoiai ma nā pae hoʻohana haʻahaʻa (maʻamau 1-10%).
Ka lawelawe ʻana a me ka mālama ʻana
Ka Mālama ʻana: E mālama i kahi anuanu, pouli, a me ka ea maikaʻi. E pani pono i nā ipu. ʻO ka mahana mālama i manaʻo ʻia ma waena o 15°C a me 25°C (59°F a me 77°F).
Mea Hoʻopale: Loaʻa iā MEHQ (Methoxyphenol) ma ke ʻano he mea hoʻopale polymerization e pale ai i ka polymerization ponoʻī i ka wā e mālama ai a me ka lawe ʻana. He mea nui e mālama i kēia mea hoʻopale no ke kūpaʻa.
Ka lawelawe ʻana: E pale i ka hoʻopili ʻana me ka wela, nā huna ahi, nā lapalapa ahi, a me nā mea hoʻoheheʻe ikaika. E hoʻohana me ka ea kūpono a e ʻaʻahu i nā lako palekana pilikino (PPE), me nā mīkina lima pale kemika, nā maka aniani palekana, a me nā lole pale.
Ola Paʻa: ʻO ka maʻamau he 12 mau mahina mai ka lā i hana ʻia ai ke mālama ʻia ma lalo o nā kūlana i ʻōlelo ʻia.
