Ndedzipi nzira dzekunyungudika cellulose ether?

Kuzeya Cuculose Consulose anaiters kunogona kuve danho rakakosha mumizidhi dzakasiyana-siyana senge mishonga, chikafu, zvinyorwa, uye kuvaka.Cellulose etanainoshandiswa zvakanyanya nekuda kwezvivakwa zvavo zvakadai sekurema, kusunga, kuumbwa-firimu, uye kusimbisa. Nekudaro, kusanzwisisika kwavo mumazhinji manyorerwo mashoma kunogona kuitika matambudziko. Nzira dzinoverengeka dzakagadziriswa kuti dzinyanye kunyungudika cellulose.

Organic sol soles:

LadoHols: Lower sortle inoremerwa Atehanol, methanol, uye isopropanol inogona kunyungudutsira cellulose. Nekudaro, ivo vanogona kunge vasina kukodzera kune ese marudzi e cellulose ana vana uye anogona kuda kupisa kwakakwirira.
Ether-doro midziyo: musanganiswa we dihthyl ether uye ethanol kana methanol kazhinji anowanzoshandiswa kunyungudika cellulose. Aya masoli anopa zvakanaka solubility uye anowanzo shandiswa mumarabharari marongero.
Katoni: Dzimwe keneti dzakafanana neacetone uye methyl ethyl ketone (meki) inogona kudzima mamwe marudzi e cellulose ana vana. Acetone, kunyanya, inoshandiswa zvakanyanya nekuda kwemutengo wayo wakaderera uye kushanda.
Esters: esters akadai seEthayl acyl uye butyl acetate inogona kunyungudika cellulose ana vana zvinobudirira. Nekudaro, ivo vangangoda kupisa kupaza zvakakwana.

Mhinduro Dzose:

Alkaline Solutions: Cellulose etana inogona kunyimwa muAlkaline Solutions yakaita seSodium Hydroxide (Naoh) kana Potassium Hydroxide (Koh). Izvi zvinopesana izvi hydronyze cellulose ana ana ana eter kuumba alkali simbi saltts, iyo inonyangadza.
Amonia Solutions: Amonia (NH3) Solutions inogona zvakare kushandiswa kunyungudutsa celloutersers uye kuumba ammonium inopenga ye ether.

Ionic zvinwiwa:

Ionic lionics organc salts ayo ari mvura pakupisa kupisa, kazhinji pazasi 100 ° C. Zvimwe zvinwiwa Ionic zvakawanikwa kuti arege kunyungudutsira cellulose anaJanterly pasina kukosha kwemamiriro ezvinhu akaomesesa. Ivo vanopa zvakanakira zvakadai sekuderera, kusimba kwakanyanya kwekunyora, uye kudzokorodza.

Yakasanganiswa solvent system:

Kubatanidza akasiyana masosi mashari anogona dzimwe nguva kusimudzira iyo solubility ye cellulose etana. Semuenzaniso, musanganiswa wemvura ine co-sol solen kunge dimethyl sulfoxide (dmso) kana n-methyl
Iyo Hansen Solubility paramende pfungwa inowanzo shandurwa kuti igadziriswe inoshanda yakasanganiswa solvent system yekunyungudza mheremalose emacoulose maCellulose macalulose mapapita ekugadzirisa iyo solubility parameter uye yekudyidzana kwavo.

Nzira dzepanyama:

Mechancal Kuchena: Yakakwirira-Shear Kusanganisa kana Swangu kunogona kubatsira mukuparadzira cellersing ma cellevelose ana vana mune solvent uye kugadzirisa kupaza kini.
Kudzora tembiricha

Chemical Shification:

Mune zvimwe zviitiko, shanduko yemakemikari ye cellulose etana inogona kuvandudza yavo yekubatanidza zvivakwa. Semuenzaniso, kuunza hydrophobic mapoka kana kuwedzera iyo degree rekutsiva kunogona kuita kuti ma cellulose ana vatambisi zvakanyanya mune organic sol.

Micellar Solutions:

Surfacts inogona kuumba micelles mune mhinduro, inogona kugadzirisacellulose etana. Nekugadzirisa surnantant kusangana uye mhinduro mhinduro, zvinokwanisika kumisikidza cellulose ana vana zvinobudirira.
Mukupedzisa, sarudzo yenzira yekunyungudika manyaniso ana vana inoenderana nezvinhu zvakaita serudzi rwechikadzi ether, inodikanwa yekufungisisa, uye yakagadzirirwa kushandisa. Imwe neimwe nzira ine zvakanakira uye zvisingakwanisi, uye vaongorori vanoramba vachiongorora nzira nyowani kuti dzivandudze kupaza kwemheremalose ana manyoro mumifananidzo akasiyana.
