Kukurukurirana pamusoro peNzira yeKuyedza Viscosity yeCellulose Ether Solution yeDry-mixed Mortar

Cellulose ether ipolymer compound yakagadzirwa kubva ku cellulose yechisikigo kuburikidza ne etherification process, uye inyanzvi yekukora uye kuchengetedza mvura.

Tsvagiridzo Yekare

Cellulose ethers yave ichishandiswa zvakanyanya mumortar yakasanganiswa yakaoma mumakore achangopfuura, anonyanya kushandiswa ndeaya asiri e-ionic cellulose ethers, anosanganisira methyl cellulose ether (MC), hydroxyethyl cellulose ether (HEC), hydroxyethyl cellulose ether Methyl cellulose ether (HEMC) uye hydroxypropyl methyl cellulose ether (HPMC). Parizvino, hapana mabhuku akawanda pamusoro penzira yekuyera viscosity ye cellulose ether solution. Munyika medu, mamwe ma standards nema monographs chete ndiwo anoratidza nzira yekuyedza viscosity ye cellulose ether solution.

Nzira yekugadzirira mhinduro ye cellulose ether

Kugadzirira kweMethyl Cellulose Ether Solution

Methyl cellulose ethers zvinoreva cellulose ethers dzine mapoka emethyl mumorekuru, akadai seMC, HEMC neHPMC. Nekuda kwekusagadzikana kweboka remethyl, mhinduro dze cellulose ether dzine mapoka emethyl dzine hunhu hwekupisa, kureva kuti, hadzinyungudike mumvura inopisa patembiricha yakakwira kupfuura tembiricha yadzo ye gelation (inenge 60-80°C). Kuti udzivise mhinduro ye cellulose ether kuti isagadzire ma agglomerates, pisa mvura pamusoro petembiricha yayo ye gel, inenge 80~90°C, wobva wawedzera upfu hwe cellulose ether mumvura inopisa, kurunga kuti ipararire, ramba uchikurunga uye utonhore. Kusvika patembiricha yakatarwa, inogona kugadzirwa kuita mhinduro ye cellulose ether yakafanana.

Hunhu hwekunyungudika kwe ethers dzisina kurapwa pamusoro pe methylcellulose

Kuti vadzivise kuungana kwe cellulose ether panguva yekunyungudika, vagadziri dzimwe nguva vanoita mushonga wemakemikari pamusoro pezvigadzirwa zve cellulose ether zvine upfu kuti vanonotse kunyungudika. Kunyungudika kwayo kunoitika mushure mekunge cellulose ether yapararira zvachose, saka inogona kuparadzirwa zvakananga mumvura inotonhora ine pH isina kusimba pasina kugadzira ma agglomerates. Kana pH yakakosha yemushonga yakakwira, nguva yekunyungudika kwe cellulose ether ine hunhu hwekunyungudika kwanonoka inopfupika. Gadzirisa pH kukosha kwemushonga kusvika pamutengo wakakwira. Alkalinity ichabvisa kunonoka kunyungudika kwe cellulose ether, zvichiita kuti cellulose ether igadzire ma agglomerates painonyungudika. Naizvozvo, pH kukosha kwemushonga inofanira kukwidzwa kana kudzikiswa mushure mekunge cellulose ether yapararira zvachose.

Hunhu hwekunyungudika kwe ethers dzine methylcellulose dzakarapwa pamusoro

Kugadzirira Hydroxyethyl Cellulose Ether Solution

Hydroxyethyl cellulose ether (HEC) solution haina hunhu hwekupisa, saka, HEC isina kugadziriswa pamusoro pemvura inozogadzirawo ma agglomerates mumvura inopisa. Vagadziri vanowanzo gadzira mishonga yemakemikari pamusoro pe HEC yakakuyiwa kuti inonoke kunyungudika, kuitira kuti ikwanise kupararira zvakananga mumvura inotonhora ine pH isina kusimba pasina kugadzira ma agglomerates. Saizvozvowo, mumushonga une alkalinity yakawanda, HEC inogonawo kugadzira ma agglomerates nekuda kwekunonoka kunyungudika. Sezvo simende slurry iri alkaline mushure mekunyoroveswa kwemvura uye pH yemushonga iri pakati pe12 ne13, mwero wekunyungudika kwe cellulose ether yakacheneswa pamusoro pe simende slurry unokurumidzawo.

Hunhu hwekunyungudika kweHEC yakarapwa pamusoro

Mhedziso uye Kuongorora

1. Maitiro ekupararira

Kuti udzivise migumisiro yakaipa panguva yekuedza nekuda kwekunyungudika kwemishonga inogadzirwa pamusoro pemvura zvishoma nezvishoma, zvinokurudzirwa kushandisa mvura inopisa pakugadzirira.

2. Maitiro ekutonhodza

Mhinduro dzeCellulose ether dzinofanira kusanganiswa uye kutonhodzwa patembiricha yekunze kuti dzideredze mwero wekutonhodza, izvo zvinoda nguva yakareba yekuedza.

3. Maitiro ekukurunga

Mushure mekunge cellulose ether yawedzerwa mumvura inopisa, iva nechokwadi chekuti unoramba uchikurunga. Kana tembiricha yemvura yadzikira pasi petembiricha yegel, cellulose ether inotanga kunyungudika, uye mhinduro yacho ichava viscous zvishoma nezvishoma. Panguva ino, kumhanya kwekukurunga kunofanira kuderedzwa. Mushure mekunge mhinduro yasvika pakunaka kwakati, inofanira kumira kwemaawa anopfuura gumi isati yatanga kuyerera zvishoma nezvishoma pamusoro kuti ibude uye iparare.

Mabhubhu emhepo muCellulose Ether Solution

4. Maitiro ekuisa mvura mumuviri

Hunhu hwe cellulose ether nemvura hunofanira kuyerwa nemazvo, uye edza kusamirira kuti mhinduro isvike pakunaka kwakanyanya usati wawedzera mvura.

5. Bvunzo reViscosity

Nekuda kwe thixotropy ye cellulose ether solution, painoyedzwa viscosity yayo, kana rotor ye rotational viscometer ikaiswa mu solution, inozokanganisa solution uye inokanganisa mhedzisiro yekuyera. Saka, mushure mekunge rotor yaiswa mu solution, inofanira kuregwa kuti imire kwemaminitsi mashanu isati yaedzwa.
