Cellulose etana (mhec)

Methyl hydroxytHyl cellulose. Heano kuongorora kweMheC:

Chimiro:

Mhec ishandiso yakagadziridzwa cellulose ether inotorwa kubva ku cellulose kuburikidza neyekutevedzana kwemakemikari maitiro. Iyo inoratidzirwa nekuvapo kwemaviri methyl uye hydroxytHyl mapoka pane iyo cellulose backbone.

Zvivakwa:

1. Solubl Solubility: MheC inonyura mumvura inotonhora, achigadzira mhinduro dzakajeka uye dziscous.
2. Kukakavara: Inoratidza yakanakisa midziyo yakakomberedza, ichiita kuti ive yakakosha se rheology modifier mune dzakasiyana siyana mafambiro.
3. Film formation: Mhec inogona kuumba inochinja uye inobatanidza mafirimu, inopa kushandiswa kwayo mukushandiswa kwayo mumatombo uye maanoman.
4. Kugadzikana: Inopa kugadzikana kune emulsions uye kumiswa, kuvandudza hupenyu hwesherufu hwezvigadzirwa zvakarongeka.
5. Adhishing: MheC anozivikanwa nezvivakwa zvayo zvinonamatira, zvinopa kuvandudza kuderedza mune zvimwe zvekushandisa.

Zvishandiso:

1. Indasitiri yekuvaka:
   • Tile Adhireles: Mhec inoshandiswa mumatanda anomhara ekuvandudza kushanda, kuchengetwa kwemvura, uye kuderedza.
   • MOTANDA uye VABEREKI: Inoshanda mumutero-yakavakirwa motamba uye inoshandura kuchengetedza kwemvura kuchengetedza uye kushanda.
   • Kuzvimiririra mishonga: MheC inoshandiswa mukuzvimiririra makomendi ekuzvimiririra kune kwayo uye kusimbisa zvivakwa.
2. Coatings uye pendi:
   • MheC inoshandiswa mumvura-yakavakirwa mapepa uye marara seanoti uye stabilizer. Iyo inobatsira kudzivirisa kushoora uye kuita kwakazara kwekucheka.
3. Mahwira:
   • MheC inoshandiswa mumanzwiro akasiyana siyana ekuwedzera kushushikana uye kugadzirisa zvinhu zvakatsauka zvemafambiro ekuzvinamatira.
4. Mishonga:
   • Mune mishonga yemishonga, mhec inoshandiswa seye binder, disintegrant, uye mafirimu-ekugadzira mumiririri mukugadzira piritsi.

Kugadzira Maitiro:

Iko kugadzirwa kweMheC kunosanganisira eretera ye cellulose ine musanganiswa we methyl chloride uye ethylene oxide. Mamiriro ezvinhu chaiwo uye reagent ratios anodzorwa kuti uwane iyo yaunoda degree rekutsiva (DS) uye kugadzirisa zvinhu zvechigadzirwa chekupedzisira.

Hwakanaka Kudzora:

Mhando dzekutonga, kusanganisira imbäiti yekuongorora yakadai seyosalear magineti resonance

Muenzaniso waMhec unoita kuti ive yakakosha yakakosha mune yakasarudzika yezvinhu, inopa kuti igadziriswe pamabasa ekuvaka, majasi, anomisheni, uye mishonga. Vagadziri vanogona kupa mamakisi akasiyana eMHEC kuti isangane zvinodiwa zvakasiyana-siyana zvemaindasitiri akasiyana siyana.
