Kukonzeresa simba re cellulose ether

Cellulose ether inowana iyo yakanyorova motsi ine mongororo yakanakisa, iyo inogona kuwedzera kugona kwekubatanidza pakati pemucheka wemarara uye nekuvandudza basa rekurwisa. Iyo inoshandiswa zvakanyanya mulastering motsi, kunze kwemadziro ekunze insulation system uye zvidhinha maruva. Mhedzisiro inoshamisa ye cellulose ether inogona zvakare kuwedzera iyo homogeneity uye yekuparadzira kugona kwezvinhu zvakasanganiswa, kongiri, uye pasi pemvura kongiri uye inokonzeresa concrete kongiri.

Cellulose ether inowedzera iyo visikopa yeiyo coment-yakavakirwa zvinhu kubva kune viscosity ye cellulose gadziriso. Iyo indekisi ye "viscosity" inowanzoshandiswa kuongorora iyo viscosity ye cellulose erthime. Iyo viscosity ye cellulose ether inowanzoreva iyo cellulose ether mhinduro ine imwe pfungwa (yakadai se2%). Kumhanya (kana kudengenyeka, kwakadai se20 rpm), kukosha kwemisangano kwakayerwa nechiridzwa chakataurwa (chakadai sechiteshi chekutenderera).

Viscosity i paramende yakakosha kuti uongorore mashandiro emheremalose ether. Yakakwira iyo viscosity ye cellulose gadziriso mhinduro, iri nani kusarudzika kwemasimendi-yakavakirwa, iri nani kudenha kune substrate, uye yakasimba yekudzivirira uye anti-kupatsanurana kugona. Kana zvisizvo zvacho zvakanyanyisa, zvichakanganisa iyo svutugadzike uye yekuvhenekera yeiyo coment-yakavakirwa zvinhu (senge inonamatira mapanga ekupenya panguva yekuvharirwa drevar kuvaka). Naizvozvo, viscosity ye cellulose erther inoshandiswa mune yakaoma-yakavhenganiswa motsi kazhinji inowanzo 15,000 ~ 60,000 mpa. S-1, kuzvimanikidza pachako-dhizaini yekunyepedzera, iyo inoda yakakwirira fluidity, inoda kuderera viscosity ye cellulose ether.

Uye zvakare, iyo inoshamisa mhedzisiro ye cellulose ether inowedzera iyo yekuda kwemvura yeiyo coment-yakavakirwa zvinhu, nokudaro ichikura gobvu.

Iyo viscosity ye cellulose gadziriso gadziriso zvinoenderana nezvinotevera zvinhu:

Molecular uremu (kana degree rePolymerization) uye kusunganidzwa kwemherekukwereta ether, mhinduro tembiricha, shear rate uye nzira yekuedza.

1. Iyo yakakwira mwero wePolymerization ye cellulose ether, iyo yakakura huremu, uye yakakwira zvikwangwani zvemhedzisiro yacho mhinduro kwayo;

2..

3. Kufanana nezvakawanda zvinwiwa, visikoka ye cellulose gadziriso mhinduro ichaderera nekuwedzera kwekudziya, uye kumusoro kwekusungirirwa kwemasangano e cellurose ether, iyo yakakura pesvedzero yekushisa;

4. Cellulose ether mhinduro kazhinji inowanzo pseudoplasticastic, iyo ine pfuma yekutsemuka. Iyo yakakura iyo Shear rate panguva yekuedzwa, iyo yakaderera viscosity.

Naizvozvo, kubatana kwemutema kuchaderedzwa nekuda kwesimba rekunze, iro rinobatsira pakuvaka kwekuvhunduka kwevhu, saka kuti moturu anogona kunge aine basa rakanaka uye kubatana panguva imwe chete. Nekudaro, iyo cellulose ether Solution icharatidza iyo Newtoniya yeNewtonian Fluid maitiro kana iyo yekuvhara yakadzika kwazvo uye iyo visikoka idiki. Kana iko kuwanda kwacho kuchikwanisika, mhinduro ichazivisa zvishoma nezvishoma pseudoplastic fluid tsika, uye yakakwira pfungwa, iyo iri pachena iyo pseudoplastical.
