Madhaka ekuzvimisikidza anotsamira pahuremu hwawo kuti agadzire hwaro hwakatsetseka, hwakatsetseka uye hwakasimba pane substrate, zvichibvumira zvimwe zvinhu kuti zvigadzirwe kana kusungirirwa, uku uchiwana nzvimbo dzakakura, dzinoshanda dzekuvaka. Naizvozvo, kunyungudika kwemvura kwakakosha hunhu hwedhaka rinozvimisa-leveling dhaka. Inofanirawo kuva nehumwe chiyero chekuchengetedza mvura uye simba rekubatanidza, pasina percolation uye kupatsanurwa, uye kuva adiabatic uye yakaderera tembiricha.
General self-leveling dhaka inoda mvura yakanaka, asi chaiyo simende slurry kuyerera kunowanzova 10-12cm chete; cellulose ether ndiyo huru yakagadzirira-yakasanganiswa dhaka additive, kunyange zvazvo mari yakawedzerwa yakaderera zvikuru, inogona kuvandudza zvakanyanya kushanda kwedhaka, iyo inogona kuvandudza dhaka risingachinji, kushanda, kushanda kwekubatanidza uye kuchengetedza mvura. Iine basa rakakosha zvikuru mumunda wedhaka rakagadzirwa rakagadzirwa.
1 Fluidity
Cellulose ether ine simba guru pakuchengetedza mvura, kuwirirana uye kushanda kwedhaka. Kunyanya sedhaka rekuzvimisa-leveling, fluidity ndechimwe chezviratidzo zvikuru zvekuongorora mashandiro ega-leveling. Iyo fluidity yedhaka inogona kugadziridzwa nekushandura huwandu hweselulosi ether pasi pemamiriro ekuona kuti yakajairika kuumbwa kwedhaka. Kunyanya kukwira kunoderedza kuyerera kwedhaka, saka, huwandu hweselulosi ether hunofanirwa kudzorwa mukati mehumwe hunoenderana.
2 Kuchengeta mvura
Mvura inochengetedza dhaka chiratidzo chakakosha chekugadzikana kwezvikamu zvemukati zvesamende dhaka. Kuti uite gel zvinhu zvizere hydrated reaction, inonzwisisika huwandu hweselulosi ether inogona kushandiswa kwenguva yakareba kuchengetedza mvura mudhaka. Kazhinji, sezvo huwandu hwe cellulose ether hunowedzera, kuchengetwa kwemvura kwedhaka kunowedzerawo. Mukuwedzera, iyo viscosity ye cellulose ether ine simba guru pakuchengetedza mvura kwedhaka; iyo yakakwirira viscosity, zviri nani kuchengetedza mvura.
3 Kuronga nguva
Cellulose ether ine blocking effect padhaka. Nekuwedzera kwe cellulose ether yemukati, nguva yekumisikidza yedhaka ichawedzerwa. Uye nepamusoro-soro ye cellulose ether, yekutanga kommoni hydration hysteresis mhedzisiro yesimende inova pachena.
4 Flexural simba uye kumanikidza simba
Kazhinji kutaura, simba ndeimwe yeakakosha maitiro ekuongorora ecementitious simentitious zvinhu kurapa musanganiswa. Iyo yekumanikidza simba uye flexural simba redhaka richaderedzwa kana zviri mukati cellulose ether zvichiwedzera.
