Cellulose ether is a polymer yakanyorwa kubva kune yakasikwa mhermanculose kuburikidza nekutsvagira maitiro, uye iri yakanaka yakanaka uye yekuchengetwa kwemvura.
Tsvaga kumashure
Cellulose ana ana vaishandiswa zvakanyanya mune yakaoma-yakavhenganiswa motokari, ishandiswe zvakanyanya masa cellulose ether methelose ether (hemc) uye hydroxyprosl methyl cellel ether (hpmc). Parizvino, hapana akawanda manyorero pane nzira yekuyera yeiyo viscosity ye cellulose erthime. Munyika medu, mamwe mimwe mimwe mitemo uye monographs anotaurisa nzira yekuedzwa yeiyo viscosity ye cellulose gadziriso.
Iyo yekugadzirira nzira ye cellulose ether mhinduro
Kugadzirira kweMethyl Cellulose Ether Solution
MetHyl Cellulose anaiters zvinoreva cellerose anaiters ine methyl mapoka mumorekuru, akadai saMC, HEMC uye HPMC. Nekuda kweiyo hydrophobicity yeboka reMethyl, Cellulose Erthose Solutions vane maMethyl Zvivakwa, ndiko kuti, ivo vanozvisimbisana nemvura inopisa pane tembiricha yakakwira kupfuura tembiricha yemagariro (anenge 60-80 ° C). Kuti udzivise iyo cellulose gadziriso yekugadzira Agglomerates, kupisa mvura pamusoro pemvura inopisa, ramba uchimhanya uye kutonhora kune iyo tembiricha yekupisa, inogona kugadziriswa mune yunifomu yemheremari yekugadzirisa.

Kuti udzivise kuunganidzwa kwemheremalose ether panguva yekunyungudika, vagadziri vanomboita zvemakemikari kurapwa pamasero ekombi kune kunonoka kushungurudzika. Maitiro ayo ekunyungudutswa anoitika mushure mekunge ma cellulose ether akaparadzaniswa zvakakwana, saka inogona kuparadzirwa zvakananga mumvura inotonhora nemvura inotsamwisa isina chaakakoshesa pasina kuumba agglomerates. Iyo yepamusoro iyo PH kukosha kweiyo mhinduro, kupfupika nguva yekunyungudza kwemheremello enther ine kunonoka kudzvinyirira kudzvinyirira. Gadzirisa kukosha kwe p p p p p p p p p p p p p p p p p p p p p p p p p p p p. Alkalinity ichabvisa iyo inononoka kushamisika yeiyo cellulose ether, ichikonzera iyo cellulose ether yekugadzira inosimbisa kana ichinyungudika. Naizvozvo, iyo pH kukosha kwemhinduro inofanirwa kurerwa kana kudzikiswa mushure mekunge cellulose ether inoparadzirwa zvakakwana.

Kugadzirira kwehydroxytHyl cellulose ether mhinduro
Hydroxethyl Cellulose Ether (Hek) mhinduro haina nzvimbo yemagariro egwenzi, saka, hec pasina kurapwa kwemusoro kuchaitawo kugarisana nemvura inopisa. Vagadziri vanowanzoita zvemakemikari zvekurapa pamapepa ehuku kune kunonoka kushungurudzika, kuitira kuti zvive zvakanyatsoputirwa mumvura inotonhora nePH kukosha kwePP kusina kwaakarerekera. Saizvozvo, mune mhinduro ine yakakwirira alkalinity, hec inogona zvakare kuumba agglomilorates nekuda kwekunonoka kushaya simba rekunyora. Sezvo simbe slurry is alkaline mushure mehydration uye iyo pfi kukosha kwemhinduro iri pakati pegumi nemaviri kusvika gumi nematatu emari yekubatwa neyekutakura mherementi yekushongedza zvakare nekukurumidza.

Mhedziso uye kuongororwa
1. Kupararira maitiro
Kuti udzivise zvinokanganisa mhedzisiro pane iyo nguva yekuedza nekuda kwekunyura zvishoma nezvishoma kwezvinhu zvekurapa zvekurapa, zvinokurudzirwa kushandisa mvura inopisa yekugadzirira.
2. Kutonhora maitiro
Cellulose Ether Solutions anofanirwa kumutswa uye akatonhorera paAmbient tembiricha kuti aderedze chiyero chinotonhorera, icho chinoda nguva dzekuyedza.
3. Kukurudzira maitiro
Mushure mekunge ma cellulose ether anowedzerwa kumvura inopisa, iva nechokwadi chekuramba uchimutsa. Kana tembiricha yemvura ikadonha pazasi peGel tembiricha, iyo cellulose ether ichatanga kunyungudika, uye mhinduro ichava zvishoma nezvishoma viscous. Panguva ino, kumhanya kwekukurudzira kunofanira kuderedzwa. Mushure mekunge mhinduro inosvika kune imwe viscosity, inoda kumira kweanopfuura maawa gumi pamberi pemabubu zvishoma nezvishoma zvishoma nezvishoma kuenda kumusoro kuti aputike uye aperere.

4. Hydaring maitiro
Hunhu hwe cellulose ether uye mvura dzinofanira kuyerwa chaizvo, uye edza kusamirira mhinduro yekusvika pane yepamusoro viscosity usati wazadza mvura.
5. Viscosity bvunzo
Nekuda kweiyo thkixotropy ye cellulose mhinduro, kana uchiedza zvavakaita, apo iyo rotic yeTortometer yaiswa mumhinduro, ichavhiringidza mhinduro uye kukanganisa mhedzisiro. Naizvozvo, mushure mekunge rotor yaiswa mumhinduro, inofanira kubvumidzwa kumira kwemaminitsi mashanu usati waedza.
