Kiyi inoshanda mapoka

  1. Acrylamide boka:Inopa polymerability kuburikidza nemahara-manyawi maitiro.
  2. Ketone Boka:Inopa nzvimbo dzekutungamira dzekurongedza-kubatanidza nemakomisheni kunge hydrzines.

Synthesis of daam

Daam inonyudzwa kuburikidza nekuita kweDicetone doro neAcrylllonitrile, inoteverwa nehasha dzenyama kana hydrolyis nhanho yekuzivisa boka renzvimbo. Maitiro ekugadzira anovimbisa chigadzirwa chepamusoro-chakanyanya chakakodzera kune maindasitiri ekushandisa maindasitiri.

Key Reaction Matanho:

  1. Diacetone doro + acrylonitrile → Intermediary compound
  2. Hydrogenation kana hydrolysis → diacetone acryleride

  • Muenzaniso:Inodzorwa zvinodhaka zvinodhaka.

5. Pepa uye kurongedza

  • Basa raDaam:Inopa yakavandudzwa simba uye unyoro hwekupaza.
  • Muenzaniso:Specialty Pepa Zvinyorwa zveChikafu uye chinwiwa kurongedza.

6. Sealants

  • Basa raDaam:Inovandudza kushanduka uye kuramba kupaza pasi pekushushikana.
  • Muenzaniso:Silicone-yakagadziridzwa samananti ekuvaka uye emagetsi ekushandisa.

Zvakanakira kushandisa daam

  1. Kuverengera Kuchinja-Kubatanidza kugona:Inoumba yakasimba network ine hydrazide-yakavakirwa muchinjiko senge ADH.
  2. Kugadzikana kweTermal:Inosimbisa kutendeka mumamiriro ekushisa-tembiricha.
  3. Unyoro kuramba:Inogadzira mafirimu emvura-leffs uye zvivakwa.
  4. Kuderera kwechitsiko:Yakachengeteka kushandisa ichienzaniswa nemamwe mamwe mashandisirwo.
  5. Kuwedzeredza Kuwedzeredza:Inoshanda nemaitiro akasiyana-siyana polymersiazation, kusanganisira emulsion, kumiswa, uye mhinduro maitiro.

Kuenderana neAdipic Dihydrazode (ADH)

Iko kusanganiswa kwaDaam naAdh kunoshandiswa zvakanyanya muCross-yakabatana polymer system. Kuita kwacho pakati peboka reKetone reDaam uye hydrazide boka muADh rinoguma nekubatana kwakakura kwazvo, kugonesa:

  • Yakashamisika michina simba.
  • Simba repamusoro rinopesana.
  • Yakagadziridzwa yekuchinjika inoenderana nezvinodiwa zvekuumbwa.

Reaction Mechanism:

  1. Ketone-Hydrazide kudyidzana:Daam + adh → hydrazone bond
  2. Zvishandiso:Waterborne polyurethane Coatings, midziyo yekuzvimiririra, uye zvimwe.

Soko Insighi uye Maitiro

Kudikanwa kwepasirese

Musika weDaam wapupurira kukura kwakakosha nekuda kwekushandiswa kwayo kwekuwedzera muco-hushamwari, kushamwaridzana kwemvura, kwakarongeka kwemvura uye wepamberi polymer masisitimu. Maindasitiri akadai sekumutakura, kuvaka, uye magetsi anotyaira kudiwa kweDaam-based mhinduro.

Kuvandudzwa

Dzazvino Kufambira Mharidzo Dzinotarisa:

  1. Bio-based Alternatives:Synthesis of daam kubva pakuvandudza zviwanikwa.
  2. High-performation yejasi:Kubatanidza muNanocomposite masisitimu ekuvandudza nzvimbo yemukati.
  3. SUSTINGLABLE KUPEDZISIRA:Shandisa mu biodegracable polymer blends.

Kubata uye kuchengetedza

  • Kuchengetedza Kuchengetedza:Dzivisa kuferelation kana ganda kusangana; Shandisa zvakakodzera zvekudzivirira pachako (PPP).
  • Mamiriro ekuchengetedza:Ramba uine inotonhorera, yakaoma, uye yakagwinya nzvimbo; Dzivisa kuoneswa nekunyorova uye kupisa.
  • HEREfu Hupenyu:Kazhinji yakagadzikana kwemwedzi inosvika makumi maviri nemana pasi pemamiriro ezvinhu akakurudzirwa.

Diacetone Acrylamide (daam) imonomer yakakomba musainzi yemazuva ano, ichipa midziyo yakasarudzika inoita kuti ive yakakosha mune yakakwirira-mashandiro ezvekuita. Kubva pane zvayo zvinokonzeresa kuwanda-kubatanidza kugona kwaro kuwanda kwekushandisa, Daam anoramba achitamba basa rekutungamira mukufambira mberi kufambira mberi, majasi, uye polymers. Kuenderana kwayo nekubuda kunowedzera matekinoroji kunozviisa semuchikamu chakakosha munguva yemberi.
