Reaction Mechanism

Hydrazone Bond Kuumbwa

ADH inopindirana nemapoka eketone kana aldehyde kuumba hydrazone bond kuburikidza ne condensation reaction, inoratidzwa ne:

  1. Kubviswa kwemvura sechigadzirwa.
  2. Kuumbwa kweiyo yakagadzikana covalent yekubatanidza.

Muenzaniso Wekuita:

 

Kuita uku kwakakosha pakugadzira zvinhu zvine kupikisa kwakanyanya kumakanika, kupisa, uye kushushikana kwezvakatipoteredza.

Zvakanakira Kushandisa ADH

  1. Kugadzikana Kwemakemikari:Hydrazone bonds inoumbwa neADH inopesana zvakanyanya nehydrolysis uye kuora.
  2. Thermal Resistance:Inowedzera kugadzikana kwekupisa kwezvinhu.
  3. Low Toxicity:Yakachengeteka kana ichienzaniswa nemamwe macross-linkers.
  4. Kuenderana kwemvura:Solubility mumvura inoita kuti ive yakakodzera kune eco-hushamwari, yemvura magadzirirwo.
  5. Zvakasiyana-siyana:Inoenderana neakasiyana epolymer matrices uye reactive mapoka.

Zvidimbu zvehunyanzvi

  • Kuchena:Kazhinji inowanikwa pa98-99% kuchena mazinga.
  • MunyundoIsingasviki 0.5% kuve nechokwadi kuenderana reactivity.
  • Particle Size:Upfu hwakatsetseka, huchifambisa kupararira kuri nyore uye kusanganisa.
  • Storage Conditions:Ramba uri munzvimbo inotonhorera, yakaoma, uye ine mhepo yakanaka, uchidzivirira kupenya kwezuva uye kuratidzwa kwemwando.

Market uye Indasitiri Maitiro

1. Sustainability Focus

Nekuchinja kuenda kune zvigadzirwa zvine hushamwari kwezvakatipoteredza, basa reADH mumvura uye yakaderera-VOC maumbirwo rave kuwedzera mukurumbira. Iyo inobatsira mukusangana neyakaomesesa mirau yezvakatipoteredza uku uchipa hukuru hwekuita.

2. Biomedical Kukura

Kugona kweADH kugadzira biocompatible uye inoshatisa mahydrogel anoiisa pakuwedzera mabasa mukuendesa zvinodhaka, engineering yetishu, uye zvinonamira pakurapa.

3. Kuvaka Indasitiri Kudiwa

Mashandisirwo eADH mumanamatirwo epamusoro-soro uye zvinonamira zvinoenderana nekukura kuri kudiwa kwezvinhu zvekuvaka zvinogara kwenguva refu, zvisingaenderane nemamiriro ekunze.

4. R&D muNanotechnology

Tsvagiridzo ichiri kusimukira inoongorora ADH yekuchinjika-inobatanidza mune nanostructured zvinhu, inosimudzira mechanic uye inopisa zvimiro zveanosanganiswa masisitimu.

Kubata uye Kuchengetedza

  • Matanho ekudzivirira:Pfeka magirovhosi, magirazi uye mask paunenge uchibata kudzivirira kushatirwa kana kufema.
  • First Aid Matanho:
    • Kufema: Enda kumhepo itsva uye tsvaga kurapwa kana zviratidzo zvikaramba zviripo.
    • Kubata Paganda: Geza zvakakwana nesipo nemvura.
  • Kupararira:Unganidza uchishandisa inert absorbent material uye urase maererano nemitemo yemunharaunda.

HEC fekitari

Adipic Dihydrazide (ADH) ine simba muchinjika-inobatanidza mumiriri uye yepakati neyakakura kunyorera mumaindasitiri. Kugadzikana kwemakemikari ayo, reactivity, uye kuenderana nezvinodiwa zvemazuva ano zvekusimudzira zvinoita kuti ive chinhu chakakosha mune zvinonamira, machira, biomedical zvinhu, uye nezvimwe. Sezvo tekinoroji ichishanduka, kukosha kweADH mukugadzira zvinhu zvepamberi kuri kuramba kuchikura, zvichisimbisa kukosha kwayo mumisika yazvino neyechiri kusimukira.
