Cellulose ether

Cellulose etherinogadzirwa kubva ku cellaulose kuburikidza nekutsvafeneka maitiro eimwe kana akati wandei etera etsenti uye yakaoma kugeda. Sekureva kwemakemikari akasiyana emakemikari eanders, cell everituets, cellaulose etana anogona kukamurwa kuita anonic, catiics uye vasingatendi vatinhi. Ionic cellulose evainers inonyanya kusanganisiraCarboxymethyl Cellulose ether (cmc); zvisiri-ionic cellulose evainers zvinosanganisira kusanganisiraMetHyl Cellulose ether (MC),Hydroxyprusyl methyl cellelose ether (hpmc)uye hydroxythyl cellulose ether.Chlorine ether (hc)zvichingoenda zvakadaro. Vasina-ioniz aungana vakakamurwa kuita eriters-inokonzerwa nemvura-simba, uye vasingamoni-madiki-madiki emvura inonyanya kushandiswa mune zvigadzirwa zvemota. Mukuvapo kweCalcium ion, Ionic Cellulose ether haina kugadzikana, saka hazviwanzo kushandiswa mune yakaoma-yakasanganiswa motsi zvigadzirwa zvinoshandiswa simende, etc. seyakasvibirira. Nonition Water-Solule Cellulose Cellulose inoshandiswa zvakanyanya muindasitiri yekuvaka yemiindasitiri nekuda kwekumiswa kwavo kwekumiswa uye kuchengetwa kwemvura.

Makemikari zvivakwa zve cellulose ether

Imwe neimwe cellulose ether ine yekutanga chimiro che cellulose -anhydroglucose chimiro. Mukuita kwekugadzira cellulose ether, iyo cellulose fiber yakatanga kupisa mumhinduro yeAlkaline, uye ikazingarapwa nemumiririri wekunyepedzera. Iyo fibrous maitiro echigadzirwa inonatswa uye inodururwa kuti iite yunifomu poda neine mwero.

Mukutonga kwekugadzira kweMC, chete methyl chloride inoshandiswa semumiriri erettification; Pamusoro pe methyl chloride, profylexe oxide inoshandiswawo kuwana hydroxyprupropylsl mapoka mukugadzirwa kweHPMC. Yakasiyana-siyana cellulose ethyl methyl uye hydroxypruppropyl substitution ratios, iyo inokanganisa iyo organic inoenderana uye yekupisa magetsi tembiricha yemhereme.
