Ndeupi musiyano uripo pakati pe cellulose ether ne cellulose?

Cellulose uye cellulose ether zvese zvakatorwa kubva kune cellulose, yakasikwa polymer inowanikwa mumasero emadziro emiti. Nekudaro, ivo vane misiyano yakasiyana mune yavo makemikari zvimiro uye zvimiro:

1. Chimiro cheKemikari: Cellulose inonzi polysaccharide ine mutsara unodzokorora zvikamu zveglucose zvakabatanidzwa ne β (1 → 4) glycosidic bonds. Iyo yakatwasuka-cheni polymer ine yakakwira dhigirii rekristaro.
2. Hydrophilicity: Cellulose inherently hydrophilic, zvichireva kuti ine hukama hwakasimba hwemvura uye inogona kutora huwandu hwakakura hwehunyoro. Ichi chivakwa chinopesvedzera maitiro ayo mumashandisirwo akasiyana siyana, kusanganisira kusangana kwayo nemvura-yakavakirwa masisitimu senge simende musanganiswa.
3. Solubility: Pure cellulose hainyungudika mumvura uye yakawanda organic solvents nekuda kweiyo yakanyanya crystalline chimiro uye yakakura yehydrogen bonding pakati pepolymer cheni.
4. Derivatization: Cellulose ether imhando yakagadziridzwa ye cellulose inowanikwa kuburikidza nekemikari inobuda. Kuita uku kunosanganisira kuunza mapoka anoshanda, akadai sehydroxyethyl, hydroxypropyl, methyl, kana carboxymethyl mapoka, kumusana we cellulose. Aya magadzirirwo anoshandura zvimiro zve cellulose, kusanganisira kunyungudika kwayo, rheological maitiro, uye kusangana nezvimwe zvinhu.
5. Solubility muMvura: Cellulose ethers inowanzonyungudika kana kuparara mumvura, zvichienderana nerudzi uye dhigirii rekutsiva. Kunyungudika uku kunoita kuti zvive zvakakosha mumaindasitiri akasiyana siyana, kusanganisira emishonga, chikafu, zvekuzora, uye kuvaka.
6. Chishandiso: Cellulose ethers inowana kushandiswa kwakapararira semaajenti ekukora, anosimbisa, mabhainda, uye maajenti ekugadzira mafirimu mumhando dzakasiyana dzezvigadzirwa uye maitiro. Mukuvaka, ivo vanowanzoshandiswa sekuwedzera mune simende-yakavakirwa zvinhu kuvandudza kushanda, kuchengetedza mvura, kunamatira, uye zvimwe zvivakwa.

Muchidimbu, nepo cellulose uye cellulose ether vachigovana mavambo akafanana, cellulose ether inogadziriswa kemikari kuti iunze chaiyo midziyo inoita kuti inyungudika kana kuparara mumvura uye yakakodzera kune akasiyana maapplication apo kutonga pamusoro pemaitiro erheological uye kusangana nezvimwe zvinhu zvinodiwa.
