Cement-based zvinhu zvinoshandiswa zvakanyanya muindasitiri yekuvaka.Zvishandiso izvi, izvo zvinowanzo sanganisira simende, jecha, mvura uye zvakaunganidzwa, zvine elastic uye inomanikidza simba, zvichiita kuti ive inofarirwa pakuvaka nekuvandudza zvivakwa.Zvisinei, kushandisa cellulose ethers sezvinowedzera kune simenti-based zvinhu zvinogona kuvandudza zvakanyanya zvivakwa zvavo, kunyanya kusimba kwavo, kushanda uye kuyerera.Cellulose ethers akagadziridzwa makabhohaidhireti makomisheni anobva ku cellulose, chinhu chakakosha chechirimwa masero madziro.
Durability
Kusimba kwesimende-yakavakirwa zvinhu chinhu chakakosha mukuvaka, kunyanya mumamiriro ezvinhu akaomarara.Nekuda kwemaitiro avo ekuchengetedza mvura, cellulose ethers inogona kuvandudza kusimba kwezvinhu izvi.Mushonga wacho unoumba zvisungo zvemuviri uye zvemakemikari nemvura, zvichibatsira kudzikisira kuparara kwehunyoro kuburikidza nekubuda uye kugadzirisa nzira yekurapa.Nekuda kweizvozvo, simende-yakavakirwa zvinhu zvinova zvakanyanya kusagadzikana nekutsemuka kana shrinkage, izvo zvakakosha pakuona kugadzikana kwenguva refu kwemaitiro.Pamusoro pezvo, cellulose ethers inogona kuvandudza kusamira kwechando-kunyunguduka kwesimende-yakavakirwa zvinhu nekudzivirira mvura kuti isapinda mumapores, nekudaro ichideredza njodzi yekukuvadzwa kubva kuchando-inonyungudutswa.
Processability
Kushanda kwesimende-based materials kunoreva kukwanisa kwavo kusanganiswa, kudirwa, uye kuumbwa pasina kupatsanurana kana kubuda ropa.Cellulose ether additives inogona kuvandudza zvakanyanya kushandiswa kwezvinhu izvi, zvichiita kuti zvive nyore kubata nekugadzirisa panguva yekuvaka.Mushonga wacho unoshanda semukobvu uye wakagadzikana, unowedzera kuwirirana uye kusimba kwesement-based materials.Uku kuvandudzwa kwekushanda kunobvumira kutonga kukuru pamusoro pekuyerera kwezvinhu, kuve nechokwadi kuti inogona kudururwa muchimiro chinodiwa uye chimiro pasina kurasikirwa kwayo kwemaitiro.Mukuwedzera, cellulose ethers inogona kuvandudza kupomba kwesimende-based materials, zvichiita kuti zvive nyore kutakurwa kuburikidza nepombi uye hoses.
kuyerera
Kuyerera kwakakosha kune simende-yakavakirwa zvinhu, kunyanya kune yega-yepamusoro kongiri, uko kuenderana uye kuyerera kwakakosha.Cellulose ethers inogona kuwedzera kuyerera kwesimende-yakavakirwa zvinhu kuti iwane yakakwira mazinga, izvo zvinobatsira mukuderedza kuumbwa kwehomwe dzemhepo kana mabhubhu muzvinyorwa.Iyo kompani inoshanda seye rheology modifier, inovandudza kuyerera kwemaitiro esimende-yakavakirwa zvinhu pasina kukanganisa ma mechanic properties.Naizvozvo, simende-yakavakirwa zvinhu zvine cellulose ethers zvinogona kuwana kufukidzwa kukuru uye kupera kwepamusoro.
mukupedzisa
Kuwedzera cellulose ether kune simende-yakavakirwa zvinhu zvinogona kubatsira kuvandudza nekusimudzira zvivakwa zvavo.Iyo inovandudza kusimba, kushanda uye kuyerera kwesimende-yakavakirwa zvinhu, zvichiita kuti ive yekuwedzera yesarudzo yemapurojekiti ekuvaka.Komboni yacho inochengeta hunyoro, inovandudza simende, uye inoderedza njodzi yekutsemuka uye kupera.Mukuwedzera, cellulose ethers inogona kusimbisa kubatana uye kuwirirana kwesimenti-based materials, zvichiita kuti zvive nani kutonga kwekuyerera kwezvinhu, zvichiita kuti zvive nyore kushandisa mukuvaka.Nokudaro, kushandiswa kwema cellulose ethers mukugadzirwa kwesimenti-based materials kunogona kuunza migumisiro yakanaka uye inobatsira.
