Mapoka Anoshanda Akakosha

  1. Acrylamide Group:Inopa kune polymerizability kuburikidza nemahara-radical maitiro.
  2. Ketone Group:Inopa reactive nzvimbo dzekuyambuka-kubatanidza nemakomponi senge hydrazines.

Synthesis yeDAAM

DAAM inogadzirwa kuburikidza nekuita kwediacetone doro neacrylonitrile, inoteverwa necatalytic hydrogenation kana hydrolysis nhanho yekusuma boka reamide. Iyo nzira yekugadzira inovimbisa yakakwira-kuchena chigadzirwa chakakodzera kushandiswa kwemaindasitiri.

Matanho Makuru Ekuita:

  1. Diacetone Doro + Acrylonitrile → Intermediary Compound
  2. Hydrogenation kana Hydrolysis → Diacetone Acrylamide

Zvakanakira Kushandisa DAAM

  1. Versatile Cross-Linking Ability:Inogadzira network yakasimba ine hydrazide-based cross-linkers seADH.
  2. Thermal Stability:Inovimbisa kuvimbika pasi pemamiriro ekupisa kwepamusoro.
  3. Unyoro Kuramba:Inogadzira mafirimu uye zvimiro zvinodzivirira mvura.
  4. Low Toxicity:Yakachengeteka kushandisa zvichienzaniswa nemamwe mamonomers.
  5. Wide Compatibility:Inoshanda neakasiyana polymerization matekiniki, anosanganisira emulsion, kumiswa, uye mhinduro maitiro.

Kuenderana neAdipic Dihydrazide (ADH)

Iko kusanganiswa kweDAAM neADH kunoshandiswa zvakanyanya muchinjika-yakabatana polymer masisitimu. Kuita pakati peboka reketone reDAAM neboka re hydrazide muADH rinoguma nekubatana kwakasimba kwehydrazone, zvichiita kuti:

  • Kuwedzerwa simba remagetsi.
  • Superior thermal resistance.
  • Tailored flexibility zvichienderana nekugadzirisa zvinodiwa.

Reaction Mechanism:

  1. Kudyidzana kweKetone-Hydrazide:DAAM + ADH → Hydrazone Bond
  2. Applications:Waterborne polyurethane coatings, kuzvirapa zvinhu, nezvimwe.

Market Insights uye Trends

Global Demand

Musika weDAAM waona kukura kwakakura nekuda kwekuwedzera kwayo kushandiswa mu eco-hushamwari, maumbirwo emvura uye epamberi polymer masisitimu. Maindasitiri akadai semota, kuvaka, uye zvemagetsi zvinofambisa kudiwa kweDAAM-based solutions.
