I-Cellulose Tellose

I-Cellulose Tellose

I-Cellulose Afers ingumndeni wama-polymers ancibilikayo asuselwa ku-cellulose, i-polymer eyenzeka ngokwemvelo etholakala ezindongeni zeseli zezitshalo. Lezi zinto zokutholwa zingamakhemikhali ama-cellulose polymers anamaqembu ahlukahlukene asebenzayo, adlulisela izakhiwo ezithile kuma-molecule. I-Cellulose Afers isetshenziswa kabanzi emikhakheni ehlukahlukene ngenxa yokuguquguquka kwayo, kufaka phakathi ukwakhiwa, amakhamishini, ukudla, izimonyo, nokuningi.

Ukunquma i-ether "enhle kakhulu" ye-cellulose kuncike kwizidingo ezithile zohlelo lokusebenza okuhlosiwe. IBHODI EBONAKALAYO YOKUZIPHATHA KWAMABHODI EZIQINISEKILE, njengokusobala, ukulekelela, kanye nekhono elenza ifilimu, kubenza balungele izinhloso ezihlukile. Nazi ezinye izithiyo ezisetshenziswa kakhulu futhi ezibhekwa kahle ze-cellulose:

  1. Methyl cellulose (MC):
    • Izakhiwo: I-MC yaziwa ngamandla ayo aphezulu okugcina amanzi, okwenza ilungele ukusetshenziswa ezinhlelweni zokuqina, ikakhulukazi embonini yezokwakha. Iphinde isetshenziswe emikhakheni nemikhiqizo yokudla.
    • Izicelo: Izakhi zodaka kanye nosimende, amaphilisi wezemithi, kanye ne-ejenti yokuqina emikhiqizweni yokudla.
  2. I-Hydroxyyethyl cellulose (HEC):
    • Izakhiwo: I-HEC inikeza i-solubility yamanzi amahle futhi iguquguqukayo ngokuya ngokulawulwa kwe-viscosity. Imvamisa isetshenziswa kuyo yomibili imikhiqizo yezimboni nasemsebenzini.
    • Izicelo: Paints kanye nezembatho, imikhiqizo yokunakekelwa komuntu siqu (ama-shampoos, lootion), anamathela, kanye nokwakheka kwemithi.
  3. I-Carboxymethyl Cellulose (CMC):
    • Izakhiwo: I-CMC ingukuncibilika kwamanzi futhi inezakhiwo ezinhle kakhulu nokuzinza. Kusetshenziswa kabanzi kwizimboni zokudla kanye nemithi.
    • Izicelo: Imikhiqizo yokudla (njenge-smicner ne-stabilizer), amakhambi, izimonyo, izindwangu, kanye noketshezi lokumba embonini kawoyela negesi.
  4. I-Hydroxypropyl methyl cellulose (HPMC):
    • Izakhiwo: I-HPMC inikeza ibhalansi enhle ye-soubity yamanzi, i-gelation ye-thermal, kanye nezakhiwo ezakha amafilimu. Kusetshenziswa kabanzi kwizicelo zokwakha kanye nezemithi.
    • Izicelo: Ama-Tile anamathela, ama-cend-based Render, ukwakheka kwemithi yomlomo, nezinhlelo zokukhishwa kwezidakamizwa ezilawulwayo.
  5. I-Ethyl Hydroxyethyl cellulose (EHEC):
    • Izakhiwo: U-Ehec waziwa ngokusobala kwayo okuphezulu nokugcinwa kwamanzi, okwenza kwalungenze kulungele izinhlelo zokusebenza ekwakheni nasezemithi.
    • Izicelo: Izithasiselo zodumbu, ama-ejenti wokuqina ezinhlamvini, kanye nezimonyo.
  6. I-Sodium carboxymethyl cellulose (NA-CMC):
    • Izakhiwo: I-NA-CMC iyi-ether engenamanzi ye-cellulose ether enamanzi amahle kakhulu wokuqina kanye nokuzinza. Ivame ukusetshenziswa ekudleni nasezisetshenzisweni ezahlukahlukene zezimboni.
    • Izicelo: Imikhiqizo yokudla (njenge-smilener ne-stabilizer), amakhambi, izindwangu, kanye nokumba uketshezi.
  7. I-Microcrystalline Cellulose (MCC):
    • Izakhiwo: I-MCC iqukethe izinhlayiya ezincane, ze-crystalline futhi ivame ukusetshenziswa njenge-binder ne-filler kumathebulethi wezemithi.
    • Izicelo: Amaphilisi wezemithi kanye nama-caplule.
  8. I-Sodium carboxymethyl starch (CMS):
    • Izakhiwo: I-CMS iyisitabane esivela ngezakhiwo ezifana ne-NA-CMC. Isetshenziswa kakhulu embonini yokudla.
    • Izicelo: Imikhiqizo yokudla (njenge-smicner ne-stabilizer), izindwangu, kanye nemithi yezemithi.

Lapho ukhetha i-cellulose ether ukuthola uhlelo oluthile, kubalulekile ukubheka izici ezinjenge-viscosity edingekayo, i-solubity, ukuqina, nezinye izici zokusebenza. Ngaphezu kwalokho, ukuhambisana namazinga okulawulwa nokucatshangelwa kwemvelo kufanele kubhekwe. Abakhiqizi bavame ukuhlinzeka ngamashidi wedatha yezobuchwepheshe ngolwazi olunemininingwane kwizakhiwo nokusetshenziswa okunconyiwe kwezithambisi ezithile ze-cellulose.
