Mune kuumbwa kweiyo yakaoma poda dhiri,cellulose etherChinhu chakakosha neyekuwedzera neyakawedzerwa kuwedzera mari, asi inogona kuvandudza zvakanyanya kukosha kwekusanganisa uye kwekuvaka kwemutya. Kuti uise izvo, zvinenge zvese zvakasanganiswa zvisina kujairika zvivakwa zvekutyaira izvo zvinogona kuoneka neziso rakashama rinopihwa ne cellulose ether. Iyo mheremalose inobviswa yakawanikwa nekushandisa cellulose kubva kune huni nekotoni, kuita nekotoni soda, uye wozotadza neyekutsauka mumiririri.
Mhando dzeCellulose ana
A. Hydroxypruppyl methyl cellulose (HPMC), iyo inonyanya kugadzirwa nekotoni yakanatswa seyakanatswa seyakagadzirwa, yakanyatsotsauswa pasi pemamiriro ezvinhu ealkaline.
B. Hydroxytlyl methylcellose (hemc), is is is is-ionic cellulose ether, ine chena hupfu mukuonekwa, kusanzwisisika uye kusavapo.
C. HydroxytHyl Cellulose (Hec), iyo isiri-ionic siractorctant, chena muchitarisiko, isina kusimba, isina kunaka uye isiriyo uye iri nyore-inoyerera poda.
Izvo zviri pamusoro hazvina-ionic cellelose eriters, uye ionic cellulose etana (senge carboxymindyl cellose cmc).
Munguva yekushandiswa kweiyo yakaoma poda powder motsi, nekuti Ionic cellulose (CMC cellulose (CMC cellulose (cmc celloulose Mune dzimwe nzvimbo kuChina, imwe yemukati madziro yakagadziriswa nechimiro chakagadziridzwa seyekutanga mashizha ekunongedza uye Shuangfei poda sezvo iyo filer shandisa cmc seyekuputika. Nekudaro, nekuti ichi chigadzirwa chinowanzoitika kune nyoro uye hachirambe mvura, inobviswa zvishoma nezvishoma nemusika. Parizvino, iyo cellulose ether inonyanya kushandiswa muChina ndeye HPMC.
Cellulose ether inonyanya kushandiswa seyekuchengetwa kwemvura mumiririri uye akakwenenzverwa mumasimendi-akavakirwa zvinhu
Basa rayo rekuchengetwa kwemvura rinogona kudzivirira iyo substrate kubva pakubata mvura yakawandisa uye kudzivisa kubhururuka kwemvura, kuitira kuti ive nemvura ine mvura yakakwana kana iri hydrate. Tora kushanda kweplasing semuenzaniso. Kana simende yakajairwa slurry inoiswa pachigadziko chemusoro, iyo yakaoma uye yekutsiva ichakurumidza kutora huwandu hwemvura kubva kuSlurry padyo neyekuvhara , saka kwete chete kukwanisa kuumba simende ine simba pamusoro peiyo substrate yeiyo substrate Kana grout raishandiswa rakatetepa, zviri nyore kuumba marara mune yese gritut. Naizvozvo, mumusoro wepamberi pekuparadza kushanda, mvura inowanzoshandiswa kunyorova yekutanga substrate kutanga, asi iyi yekuvhiya haisi kungoita basa uye kupedza nguva, asiwo kusavapo kwemhando kwakaoma kudzora.
Kazhinji, kuchengetwa kwemvura kwemvura simende kusimbisa kunowedzera nekuwedzera kwezvinhu zvemukati meruculose ether. Iyo yakakura iyo visikopa yeiyo yakawedzerwa cellulose ether, zvirinani kuchengetwa kwemvura.
Kuwedzera pakuchengetwa kwemvura uye kurerutsa, cellulose ether inokanganisa zvimwe zvivakwa zvekemende, sekudzosera, kupinza mweya, uye kuwedzera kusungwa. Cellulose etera inodzora mamiriro ekuisa uye kuomesa maitiro eiyo simende, nekudaro inowanzogara nguva yekushanda. Naizvozvo, dzimwe nguva inoshandiswa seyakawirirana.
Nekuvandudzwa kweakaoma-yakasanganiswa dhaka,cellulose etherrave rakakosha simende dorman admixture. Nekudaro, kune marudzi mazhinji uye kutaurwa kwemheremalose ether, uye mhando pakati peBatch ichiri kuchinjika.
