Zvimiro zveMethyl Cellulose

Methyl cellulose (MC) is a cellulose ether ine huwandu hwakawanda hwekushandisa mumaindasitiri akasiyana, kusanganisira chikafu, mishonga, uye kuvaka. Zvimwe zvezvivakwa zveMC zvinosanganisira:

  1. Solubility: MC inonyungudika mumvura uye inogona kugadzira mhinduro yakajeka uye yakagadzikana pane tembiricha yekamuri. Iyo zvakare inonyungudika mune mamwe organic solvents, senge ethanol uye methanol.
  2. Viscosity: Iyo viscosity yeMC mhinduro inotsamira pane akati wandei zvinhu, kusanganisira dhigirii rekutsiva, uremu hwemamorekuru, uye kusungirirwa kweMC mhinduro. MC mhinduro dzinoratidza dzisiri-Newtonian kuyerera maitiro, zvichireva kuti viscosity inoshanduka neshear rate.
  3. Kugadzira firimu: MC inogona kugadzira firimu kana yanyungudutswa mumvura yobva yaoma. Iyo firimu yakaumbwa neMC inochinjika, yakajeka, uye ine yakanaka inodzivirira zvivakwa.
  4. Thermal kugadzikana: MC ine kugadzikana kwakanaka kwekupisa uye inogona kumira tembiricha inosvika 200 ° C pasina kuderera kwakanyanya.
  5. Kugarisana: MC inowirirana nezvimwe zvinhu zvakawanda, zvinosanganisira mamwe cellulose ethers, starch, uye mapuroteni.
  6. Hydrophilicity: MC yakanyanya hydrophilic, zvichireva kuti ine hukama hwakasimba hwemvura. Ichi chivakwa chinoita kuti MC ibatsire mukuumbwa uko kuchengetwa kwemvura kwakakosha, senge muchikafu uye zvigadzirwa zvekuchengeta munhu.

Pakazere, zvimiro zveMC zvinoita kuti ive zvinhu zvakasiyana-siyana zvinogona kushandiswa mumashandisirwo mazhinji akasiyana.
