Doka rinozvimisa rinogona kuvimba nehuremu hwaro kuti riumbe hwaro hwakati sandara, hwakatsetseka uye hwakasimba pane substrate yekuisa kana kubatanidza zvimwe zvinhu. Inogonawo kuita kuvaka kwakanaka panzvimbo yakakura. Kunyungudika kwemvura chinhu chakakosha chedhaka rekuzvimisa. ; Pamusoro pezvo, inofanirwawo kuve nekumwe kuchengetedza kwemvura uye kusimba kwekubatanidza, kusaburitsa kupatsanurwa kwemvura, uye kuve nehunhu hwekudzivirira kupisa uye kuderera kwekushisa kukwira.
Kazhinji, dhaka rekuzvimisikidza rinoda mvura yakanaka.Cellulose etherchinhu chikuru chekuwedzera kune yakagadzirira-yakasanganiswa dhaka. Kunyangwe huwandu hwekuwedzera hwakaderera kwazvo, hunogona kuvandudza zvakanyanya kuita kwedhaka. Inogona kuvandudza kuwirirana, kushanda kwekushanda, uye Adhesion properties uye mvura yekuchengetedza zvinhu, etc. Inoita basa rinokosha mumunda wedhaka yakagadzirira-yakasanganiswa.
Fluidity
Cellulose etherine simba rakakosha pakuchengetedza mvura, kuenderana, uye kuita kwekuvaka kwedhaka rekuzvimisa. Kunyanya yekuzvimisa-leveling dhaka, fluidity ndechimwe chezviratidzo zvikuru zvekuongorora kuzvidzora kuita. Pachikonzero chekuvimbisa kuumbwa kwechinyakare kwedhaka, kuyerera kwedhaka kunogona kugadziriswa nekushandura huwandu hweselulosi ether. Nekudaro, yakanyanya kuwanda dosage inoderedza kuyerera kwedhaka, saka dosage ye cellulose ether inofanirwa kudzorwa mukati mehumwe hunoenderana.
Kuchengetedza mvura
Kuchengetedzwa kwemvura yematope chiratidzo chakakosha chekuyera kugadzikana kwezvikamu zvemukati zvesamende nyowani. Kuti uite zvizere hydration reaction yeiyo gel zvinhu, inonzwisisika huwandu hweselulosi ether inogona kuchengetedza mwando mudhaka kwenguva yakareba. Kazhinji kutaura, chiyero chekuchengetedza mvura yeslurry inowedzera nekuwedzera kwemukati we cellulose ether. Basa rekuchengetedza mvura re cellulose ether rinogona kudzivirira substrate kuti isatora mvura yakawandisa nekukurumidza uye ichitadzisa kubuda kwemvura, nokudaro kuve nechokwadi chekuti slurry nharaunda inopa mvura yakakwana yesamende hydration. Mukuwedzera, iyo viscosity ye cellulose ether inewo simba guru pakuchengetedza mvura kwedhaka. Iyo yakakwirira viscosity, zviri nani kuchengetedza mvura. Cellulose ethers ane general viscosity ye400 mpa.s anonyanya kushandiswa mumatope ekuzvimisa, ayo anogona kuvandudza kushanda kwedhaka uye kunatsiridza density yedhaka.
Nguva ye coagulation
Cellulose etherine chimwe chinokanganisa padhaka. Sezvo zvinyorwa zve cellulose ether zvinowedzera, nguva yekuisa yedhaka inowedzera. Kudzoreredza kuita kwe cellulose ether pane simende slurry kunonyanya kuenderana nehuwandu hwekutsiviwa kwemapoka ealkyl uye ine hukama hudiki nehuremu hwayo hwemamorekuru. Iyo idiki iyo alkyl inotsiva dhigirii, iyo yakakura iyo hydroxyl yemukati, uye zvakanyanya kuoneka maitiro ekudzoreredza. Uye iyo yakakwirira yemukati we cellulose ether, zvakanyanya kujeka iyo yakaoma firimu layer iri mukudzoreredza kwekutanga hydration ye simenti, uye nekudaro, zvakanyanya kuoneka kudzoreredza mhedzisiro.
Flexural simba uye kumanikidza simba
Simba ndeimwe yeakakosha ekuongorora zviratidzo zvekusimba kwesimba resimende-yakavakirwa simende zvinhu pamusanganiswa. Sezvo zviri mukati me cellulose ether zvichiwedzera, iyo yekumanikidza simba uye flexural simba redhaka rinoderera. Inoda kudzorwa mukati meimwe nzira inonzwisisika.
Bonding simba
Cellulose ether ine simba guru pakubatanidza zvinhu zvedhaka. Cellulose ether inoumba firimu repolymer rine chisimbiso pakati pe simenti hydration particles mu liquid phase system, iyo inosimudzira mvura yakawanda mupolymer firimu kunze kwemasimende zvidimbu, izvo zvinoita kuti kuzara kwe hydration ye simenti, nokudaro kuvandudza Bond simba. mushure mekuoma kwe slurry. Panguva imwecheteyo, huwandu hwakakodzera hweselulosi ether hunosimudzira plastiki uye kuchinjika kwedhaka, inoderedza kuomarara kwenzvimbo yekuchinja pakati pedhaka nehwaro zvinhu, uye inoderedza kugona kutsvedza pakati penzvimbo. Kusvika kumwero wakati, iyo yekubatanidza mhedzisiro pakati pedhaka uye base zvinhu inowedzerwa. Uye zvakare, nekuda kwekuvapo kwe cellulose ether mune simende slurry, yakakosha interface yekushandura zone uye interface layer inoumbwa pakati pemateki edhaka uye zvigadzirwa zvehydration. Iyi interface layer inoita kuti iyo interface yekushandura zone iwedzere kushanduka uye kuderera kusimba. Nokudaro, Jehovha, kuitira kuti dhaka rive nesimba rakasimba rekubatanidza.
