DAAM: Uruganda rwa Diacetone Acrylamide

Diacetone Acrylamide (DAAM) ni monomer itandukanye ikoreshwa muburyo butandukanye bwa polymerisation kugirango ikore ibisigazwa, ibifuniko, ibifunga, nibindi bikoresho bisaba kongera ubushyuhe bwumuriro, kurwanya amazi, hamwe nuburyo bwo gufatira hamwe. DAAM iragaragara cyane kubera imiterere yihariye ya chimique hamwe nubushobozi bwo guhura nigikorwa cyo guhuza hamwe nibindi bikoresho, nka adipic dihydrazide (ADH), bikavamo ibikoresho bifite imikorere myiza.

Amatsinda y'ingenzi akora

  1. Itsinda rya Acrylamide:Gutanga umusanzu kuri polymerizability ukoresheje reaction-yubusa.
  2. Itsinda rya Ketone:Itanga imbuga zifatika zo guhuza hamwe nibintu nka hydrazine.

Synthesis ya DAAM

DAAM ikomatanyirizwa hamwe binyuze muri reaction ya alcool ya diacetone hamwe na acrylonitrile, ikurikirwa na hydrogenation ya catalitike cyangwa hydrolysis intambwe yo kumenyekanisha itsinda rya amide. Igikorwa cyo kubyaza umusaruro ibicuruzwa bitanga ubuziranenge bukwiranye ninganda zikoreshwa mu nganda.

Intambwe zingenzi zo kwitwara:

  1. Inzoga ya Diacetone + Acrylonitrile ound Hagati
  2. Hydrogenation cyangwa Hydrolysis → Diacetone Acrylamide

Porogaramu ya DAAM

1. Ibifatika

  • Uruhare rwa DAAM:Kuzamura imitungo ihuza guteza imbere guhuza no gutuza ubushyuhe.
  • Urugero:Umuvuduko ukabije wumuvuduko hamwe nimbaraga zishishwa kandi ziramba.

2. Amazi yo mu mazi

  • Uruhare rwa DAAM:Ibikorwa nkibikorwa bya firime itanga amazi meza kandi yoroheje.
  • Urugero:Irangi ryiza ninganda zo kwangirika no kwambara birwanya.

3. Abakozi barangiza imyenda

  • Uruhare rwa DAAM:Itanga imashini iramba irangiza hamwe na anti-wrinkle.
  • Urugero:Koresha mubitari ibyuma birangiza imyenda.

4. Hydrogels hamwe na Biomedical Porogaramu

  • Uruhare rwa DAAM:Kugira uruhare mu gushiraho hydrogels ya biocompatible.
  • Urugero:Kugenzura uburyo bwo gutanga ibiyobyabwenge.

5. Impapuro no gupakira

  • Uruhare rwa DAAM:Itanga imbaraga zinoze hamwe nubushuhe bwinzitizi.
  • Urugero:Impapuro zihariye zo gupakira ibiryo n'ibinyobwa.

6. Ikidodo

  • Uruhare rwa DAAM:Itezimbere guhinduka no kurwanya gucikamo ibice.
  • Urugero:Silicone-yahinduwe kashe yo kubaka no gukoresha amamodoka.

Ibyiza byo gukoresha DAAM

  1. Ubushobozi butandukanye bwo guhuza:Shiraho imiyoboro ikomeye hamwe na hydrazide-ishingiye ku guhuza nka ADH.
  2. Ubushyuhe bwumuriro:Iremeza ubunyangamugayo mubihe by'ubushyuhe bwo hejuru.
  3. Kurwanya Ubushuhe:Gukora firime zangiza amazi.
  4. Uburozi buke:Umutekano wo gukoresha ugereranije nabandi bashoramari.
  5. Ubwuzuzanye bwagutse:Gukorana nubuhanga butandukanye bwa polymerisation, harimo emulion, guhagarika, hamwe nuburyo bwo gukemura.

Guhuza na Adipic Dihydrazide (ADH)

Guhuza DAAM na ADH bikoreshwa cyane muri sisitemu ihuza polymer. Igisubizo hagati yitsinda rya ketone ya DAAM nitsinda rya hydrazide muri ADH bivamo guhuza hydrazone iramba cyane, igushoboza:

  • Kongera imbaraga za mashini.
  • Kurwanya ubushyuhe bukabije.
  • Ihindagurika ryihariye bitewe nibisabwa.

Uburyo bwo kubyitwaramo:

  1. Imikoranire ya Ketone-Hydrazide:DAAM + ADH Bond Inkunga ya Hydrazone
  2. Porogaramu:Amazi ya polyurethane yamazi, ibikoresho byo kwikiza, nibindi byinshi.

Ubushishozi bwisoko

Ibisabwa ku Isi

Isoko rya DAAM ryabonye iterambere ryinshi bitewe n’uko rikoreshwa cyane mu bidukikije byangiza ibidukikije, amazi y’amazi ndetse na sisitemu ya polymer igezweho. Inganda nkimodoka, ubwubatsi, hamwe na elegitoroniki zitwara ibisabwa kubisubizo bishingiye kuri DAAM.

Guhanga udushya

Iterambere rya vuba ryibanda kuri:

  1. Ibinyabuzima bishingiye kuri Bio:Synthesis ya DAAM ivuye mumikoro ashobora kuvugururwa.
  2. Imyenda yo hejuru cyane:Kwinjiza muri nanocomposite sisitemu yo kuzamura imiterere yubutaka.
  3. Gupakira birambye:Koresha muri biodegradable polymer ivanze.

Gukoresha no Kubika

  • Uburyo bwo kwirinda umutekano:Irinde guhumeka cyangwa guhuza uruhu; koresha ibikoresho byihariye byo kurinda (PPE).
  • Uburyo bwo kubika:Gumana ahantu hakonje, humye, kandi uhumeka neza; irinde guhura nubushuhe nubushuhe.
  • Ubuzima bwa Shelf:Mubisanzwe bihamye kugeza kumezi 24 mubihe bisabwa.

Diacetone Acrylamide (DAAM) ni monomer ikomeye mubikoresho bigezweho siyanse, itanga imitungo idasanzwe ituma ari ntangarugero mubikorwa byo hejuru. Kuva ubushobozi bwayo butandukanye bwo guhuza ibikorwa byogukoresha, DAAM ikomeje kugira uruhare runini mugutezimbere ibifatika, ibifuniko, na polymers. Guhuza kwayo hamwe nikoranabuhanga rirambye rishyira mubikorwa nkibintu byingenzi muguhanga udushya.
