DAAM: hale hana Diacetone Acrylamide

ʻO ka Diacetone Acrylamide (DAAM) he monomer versatile i hoʻohana ʻia i nā ʻano hana polymerization e hana ai i nā resins, nā uhi, nā adhesives, a me nā mea ʻē aʻe e koi ana i ka hoʻonui ʻana i ka thermal stability, ka pale wai, a me nā waiwai adhesion. Kūleʻa ʻo DAAM ma muli o kāna ʻano kemika kūʻokoʻa a me ka hiki ke hana i nā hopena cross-linking me nā pūhui ʻē aʻe, e like me adipic dihydrazide (ADH), ka hopena i nā mea me ka hana ʻoi aku ka maikaʻi.

Na Waiwai Kemika o DAAM

  • IUPAC Inoa:N-(1,1-Dimethyl-3-oxo-butyl)acrylamide
  • ʻO ke kumu hoʻohālike kimemika:C9H15NO2
  • Kaumaha Molekala:169.22 g/mol
  • Helu CAS:2873-97-4
  • ʻAno:Paʻa keʻokeʻo keʻokeʻo a pauda paha
  • Hiki ke hoʻoheheʻe:Hiki ke hoʻoheheʻe ʻia i ka wai, ethanol, a me nā mea hoʻoheheʻe polar ʻē aʻe
  • Lae hehee:53°C a i 55°C

Nā Pūʻulu Hana Nui

  1. Hui Acrylamide:Hāʻawi i ka polymerizability ma o nā hopena radical free-radical.
  2. Hui Ketone:Hāʻawi i nā paena reactive no ka hoʻopili ʻana me nā pūhui e like me nā hydrazines.

Hoʻohui ʻia o DAAM

Hoʻopili ʻia ʻo DAAM ma o ka hopena o ka waiʻona diacetone me ka acrylonitrile, a ukali ʻia e kahi catalytic hydrogenation a i ʻole hydrolysis step e hoʻolauna i ka hui amide. ʻO ke kaʻina hana e hōʻoia i kahi huahana maʻemaʻe kiʻekiʻe e kūpono i nā noi ʻoihana.

Nā ʻanuʻu pane ʻōlelo nui:

  1. ʻO ka waiʻona Diacetone + Acrylonitrile → Hui Kūwaena
  2. Hydrogenation a i ʻole Hydrolysis → Diacetone Acrylamide

Nā noi o DAAM

1. Nā mea hoʻopili

  • Ke kuleana o DAAM:Hoʻonui i nā waiwai hoʻopaʻa ma o ka paipai ʻana i ka hoʻopaʻa ʻana a me ke kūpaʻa wela.
  • Laʻana:ʻO nā mea hoʻopili pili paʻi me ka ikaika a me ka lōʻihi o ka peel.

2. ʻO nā uhi wai

  • Ke kuleana o DAAM:Hana ma ke ʻano he mea hana kiʻiʻoniʻoni e hāʻawi ana i ke kūpaʻa wai maikaʻi a me ka maʻalahi.
  • Laʻana:ʻO nā pena hoʻonaninani a me nā ʻoihana no ka ʻino a me ke kūpaʻa ʻana.

3. Na Agena Hoopau lole

  • Ke kuleana o DAAM:Hāʻawi i nā mea paʻi paʻa paʻa a me nā waiwai anti-wrinkle.
  • Laʻana:E hoʻohana i nā mea hao ʻole no nā lole.

4. Hydrogels a me nā noi lāʻau lapaʻau

  • Ke kuleana o DAAM:Hāʻawi i ka hana ʻana o nā hydrogels biocompatible.
  • Laʻana:Nā ʻōnaehana lawe lāʻau hoʻomalu.

5. Pepa a me ka Packaging

  • Ke kuleana o DAAM:Hāʻawi i ka maikaʻi o ka ikaika a me nā waiwai pale.
  • Laʻana:ʻO nā uhi pepa kūikawā no ka hoʻopili ʻana i nā meaʻai a me nā mea inu.

6. Nā mea hoʻopaʻa

  • Ke kuleana o DAAM:Hoʻomaikaʻi i ka maʻalahi a me ke kū'ē i ka haki ʻana ma lalo o ke kaumaha.
  • Laʻana:ʻO nā sealants i hoʻololi ʻia e Silicone no ke kūkulu ʻana a me nā noi kaʻa.

Nā pōmaikaʻi o ka hoʻohana ʻana iā DAAM

  1. Hiki ke hoʻopili keʻa like ʻole:Hoʻokumu i nā pūnaewele ikaika me nā cross-linkers-based hydrazide e like me ADH.
  2. Paʻa wela:E hōʻoia i ka pono ma lalo o nā kūlana wela kiʻekiʻe.
  3. ʻAi ʻole i ka wai:Hana i nā kiʻiʻoniʻoni a me nā hale.
  4. Haʻahaʻa ʻawaʻawa:ʻOi aku ka palekana e hoʻohana i ka hoʻohālikelike ʻana i kekahi mau monomers ʻē aʻe.
  5. Hoʻohālikelike ākea:Hana me nā ʻenehana polymerization like ʻole, me ka emulsion, ka hoʻokuʻu ʻana, a me nā kaʻina hana hoʻonā.

Hoʻohālikelike me Adipic Dihydrazide (ADH)

Hoʻohana nui ʻia ka hui ʻana o DAAM me ADH i nā ʻōnaehana polymer cross-linked. ʻO ka hopena ma waena o ka hui ketone o DAAM a me ka hui hydrazide i ADH ka hopena i kahi pilina hydrazone lōʻihi loa, e hiki ai:

  • Hoʻonui i ka ikaika mechanical.
  • Kūleʻa wela kiʻekiʻe.
  • Hiki ke hoʻololi ʻia ma muli o nā koi o ka formulation.

Mechanism:

  1. Ketone-Hydrazide Interaction:DAAM + ADH → Paʻa Hydrazone
  2. Nā noi:ʻO nā uhi polyurethane wai, nā mea hoʻōla ponoʻī, a me nā mea hou aku.

Nā ʻike mākeke a me nā ʻano

Koi honua

Ua ʻike ka mākeke no DAAM i ka ulu nui ʻana ma muli o kona hoʻohana nui ʻana i ka eco-friendly, waterborne formulations a me nā ʻōnaehana polymer kiʻekiʻe. ʻO nā ʻoihana e like me ka automotive, ke kūkulu ʻana, a me nā mea uila e hoʻokau i ka noi no nā hopena e pili ana i ka DAAM.

Mea hou

ʻO nā holomua hou e pili ana i:

  1. Nā ʻano ʻē aʻe e pili ana i ka bio:Synthesis o DAAM mai nā kumuwaiwai hou.
  2. ʻO nā uhi hana kiʻekiʻe:Hoʻohui i nā ʻōnaehana nanocomposite no ka hoʻonui ʻana i nā waiwai o ka ʻili.
  3. Packaging hoʻomau:E hoʻohana i nā hui polymer biodegradable.

Ka mālama ʻana a me ka mālama ʻana

  • Hoʻomalu palekana:E pale i ka inhalation a i ʻole ka ʻili; e hoʻohana i nā lako pale pilikino kūpono (PPE).
  • Kūlana mālama:E mālama i kahi anuanu, maloʻo, a me ka makani maikaʻi; pale aku i ka ma'u a me ka wela.
  • Ke ola papa:Kūpaʻa maʻamau a hiki i 24 mahina ma lalo o nā kūlana i ʻōlelo ʻia.

ʻO ka Diacetone Acrylamide (DAAM) he monomer koʻikoʻi i ka ʻepekema waiwai hou, e hāʻawi ana i nā waiwai kūʻokoʻa e pono ai i nā noi kiʻekiʻe. Mai kona hiki ke hoʻopili ʻia a hiki i kāna kikoʻī noiʻi ākea, hoʻomau ka DAAM i ka hana koʻikoʻi i ka holomua ʻana i nā adhesives, coatings, a me polymers. ʻO kona kūlike me nā ʻenehana hoʻomau e kū nei e hoʻonoho iā ia ma ke ʻano he mea koʻikoʻi i nā mea hou e hiki mai ana.
