Cellulose ether semuenzaniso

Cellulose enzande muenzaniso ndeye polymer yakagadzirwa nemheremalose ine ether chimiro. R Mhete dzega dzega dzeglucose muCellulose Macromolecule ine mapoka matatu eHydroxyl, iyo yekutanga hydroxyl boka kabhoni kabhoni, uye yechipiri hydroxyl boka pane yechipiri kabhoni maatomu. Iyo hydrogen mu hydroxyl boka inotsiviwa neiyo hydrocarbon boka kuti riite cellulose. Icho chigadzirwa chekutsiva kwehydroxyl hydrogen ne hydrocarbon boka mu cellulose polymer. Cellulose is polyhydroxy polymer inowanzoitika kuti hapana mbichana kana kunyungudika. Cellulose inogona kunyungudutswa mumvura, Dilute Alkali solution uye organic solvent mushure mekuwedzera, uye ine iyo thermoplastic prezerties.

Cellulose ether ndiyo nguva yakajairika yezvinhu zvigadzirwa zvakagadzirwa nekuita kweAlkali cellulose uye kuendenamira mumiririri pasi pemamwe mamiriro ezvinhu. Alkali cellulose inotsiviwa nekusiyana kwekunyengedza vamiririri kuti vawane vakasiyana cellulose ana vana.

Maererano neIonization zvivakwa zvevakatsauka, cellulose eters semuenzaniso chinogona kukamurwa kuita ionic (senge carboxymeyl cellemose) uye isiri-ionic (yakadai methyl cellowose) mitezo miviri.

Sekureva kwerudzi rwekutsiva, cellulose vaitenda semuenzaniso vanogona kukamurwa kuita kamwechete (senge methyl cellulose) uye sevakasanganiswa (sevakasanganiswa (senge hydroxpropropyl methelose). Sekureva kwaSalubility, inogona kukamurwa kuita mvura svutugadzike (senge hydroxythyl cellulose) uye organic solvent salubilse (senge ethyl cellulose). Dry yakasanganiswa motsi inonyanya kushandisa mheremhero yemvura, iyo inogona kugoverwa mukukurumidza-kupera simba uye kunonoka kunyungudusa mhando mushure mekurapwa kwemusoro.

Admixture anotamba yakakosha basa mukuvandudza zvinhu zvekuomeswa-dema Chikamu chakakura chechiitiko mumusika wemba chinopihwa nevatorwa nevatorwa, uye chirevo chechigadzirwa chakapihwawo nevatengesi. Nekuda kweizvozvo, mutengo wezvigadzirwa zvakaoma-mongororo zviripo zvakakwirira, uye zvakaoma kugutsikana zvakajairika mononry merare uye kupururudza dhafuro nehuwandu hukuru uye nzvimbo yakakura. Yakakwira-yekupedzisira misika zvigadzirwa zvinodzorwa nemakambani ekunze, akaoma moter Vagadziri akaderera purofiti, mutengo usina kunaka wekutadza; Iko kushandiswa kweAdminture Inoshayikwa yakarongeka uye yakatariswa kutsvagisa, kutevera bofu kutevedzera mafambiro ekunze.

Kuchengetwa kwemvura ndeyekiyi ndeyekushambadzira kwekuvandudza mari yekuchengetwa kwemvura yekuomeswa kwekuomeswa kwemotokari yakasanganiswa uye zvakare chimwe chekiyi yekubvumirana kuti uone mutengo wezvinhu wakaoma wakasanganiswa. Basa guru re cellulose ether richiramba richichengeta mvura.

Chiito chechiitiko chemheremalose ether mumota zviri seanotevera:
