Otu ndị na-arụ ọrụ igodo

  1. Otu Acrylamide:Na-atụnye aka na polymerizability site na mmeghachi omume radical free.
  2. Otu Ketone:Na-enye saịtị na-emeghachi omume maka ijikọ njikọ na ogige dị ka hydrazines.

Ọnụ ego nke DAAM

A na-emepụta DAAM site na mmeghachi omume mmanya diacetone na acrylonitrile, na-esote usoro hydrogenation catalytic ma ọ bụ usoro hydrolysis iji webata otu amide. Usoro mmepụta na-eme ka ngwaahịa dị ọcha dị elu dị mma maka ngwa mmepụta ihe.

Usoro mmeghachi omume bụ isi:

  1. Mmanya Diacetone + Acrylonitrile → Ngwakọta etiti
  2. Hydrogenation ma ọ bụ Hydrolysis → Diacetone Acrylamide

  • Ọrụ DAAM:Na-enye mmecha akwụkwọ akụkọ na-adịgide adịgide yana ihe mgbochi mgbochi.
  • Ọmụmaatụ:Jiri na-abụghị ígwè emecha akwa.

4. Hydrogels na Ngwa Biomedical

  • Ọrụ DAAM:Na-enye aka na nhazi nke hydrogels biocompatible.
  • Ọmụmaatụ:Usoro nnyefe ọgwụ a na-achịkwa.

5. Akwụkwọ na nkwakọ ngwaahịa

  • Ọrụ DAAM:Na-enye ike na ihe mgbochi mmiri dị mma.
  • Ọmụmaatụ:Ihe mkpuchi akwụkwọ pụrụ iche maka nkwakọ nri na ihe ọṅụṅụ.

6. Sealants

  • Ọrụ DAAM:Na-eme ka mgbanwe na iguzogide mgbawa n'okpuru nrụgide.
  • Ọmụmaatụ:Silicone emezigharịrị sealants maka owuwu na ngwa ụgbọ ala.

Uru nke Iji DAAM

  1. Ikike imekọ ihe ọnụ:Na-emepụta netwọk siri ike na ndị na-ejikọta hydrazide dị ka ADH.
  2. Nkwụsi ike okpomọkụ:Na-eme ka iguzosi ike n'ezi ihe n'okpuru ọnọdụ okpomọkụ dị elu.
  3. Nguzogide mmiri:Na-emepụta ihe nkiri na ihe ndị na-egbochi mmiri.
  4. Nsi dị ala:Ọ dị mma iji tụnyere ụfọdụ monomers ọzọ.
  5. Ndakọrịta sara mbara:Na-arụ ọrụ na usoro polymerization dị iche iche, gụnyere emulsion, nkwusioru, na usoro ngwọta.

Ndakọrịta na Adipic Dihydrazide (ADH)

Nchikota DAAM na ADH na-ejikarị eme ihe na sistemu polymer jikọtara ọnụ. Mmeghachi omume n'etiti ketone otu DAAM na otu hydrazide na ADH na-ebute njikọ hydrazone na-adịgide adịgide nke ukwuu, na-enyere:

  • Emelitere ike n'ibu.
  • Nguzogide okpomọkụ kachasị elu.
  • Ngbanwe ahaziri dabere n'usoro ihe achọrọ.

Usoro mmeghachi omume:

  1. Ketone-Hydrazide Mmekọrịta:DAAM + ADH → Hydrazone Bond
  2. Ngwa:Ihe mkpuchi polyurethane nke mmiri, ihe na-agwọ onwe ya, na ihe ndị ọzọ.

Ọchịchọ zuru ụwa ọnụ

Ahịa maka DAAM ahụtala uto dị ukwuu n'ihi ojiji ya na-abawanye na eco-friendly, usoro mmiri na sistemu polymer dị elu. Ụlọ ọrụ dị ka ụgbọ ala, ihe owuwu, na ngwa eletrọnịkị na-akpali ọchịchọ maka ngwọta dabere na DAAM.

Ihe ohuru ohuru

Ọganihu na nso nso a gbadoro anya na:

  1. Nhọrọ dabere na bio:Nchịkọta DAAM sitere na akụrụngwa enwere ike imeghari.
  2. Mkpuchi na-arụ ọrụ dị elu:Ntinye n'ime sistemu nanocomposite maka akụrụngwa elu emelitere.

  • Akpachara anya maka nchekwa:Zere iku ume ma ọ bụ kọntaktị anụ ahụ; jiri akụrụngwa nchedo onwe onye dabara adaba (PPE).
  • Ọnọdụ Nchekwa:Debe ebe dị jụụ, kpọrọ nkụ, na ikuku nke ọma; zere ikpughe na mmiri na okpomọkụ.
  • Ndụ nchekwa:Ọ kwụsiri ike ruo ọnwa 24 n'okpuru ọnọdụ akwadoro.

Diacetone Acrylamide (DAAM) bụ monomer dị oke egwu na sayensị akụrụngwa ọgbara ọhụrụ, na-enye akụrụngwa pụrụ iche na-eme ka ọ dị mkpa na ngwa arụmọrụ dị elu. Site na ikike ijikọ ọnụ ya na ụdị ngwa ngwa ya sara mbara, DAAM na-aga n'ihu na-arụ ọrụ dị mkpa n'ịkwalite adhesives, mkpuchi, na polymers. Ndakọrịta ya na teknụzụ na-adịgide adịgide na-edobe ya dị ka akụkụ dị mkpa na ihe ọhụrụ n'ọdịnihu.
