Ndeipi tsanangudzo yemvura inoderedza?
Mvura inoderedza mumiririri rudzi rwekongiri musanganiswa, iyo inogona kuvandudza kushanda kwekongiri, kuderedza kushandiswa kwesimba rekuvaka uye kuvandudza kushanda kwekuvaka. Mukongiri, mvura inoderedza mumiriri inowedzerwa kumusanganiswa we simenti particles dispersion effect, iyo inogona kukwidziridza kushanda kwesement. Pasi pemamiriro ekuchengetedza kongiri inodonha nguva dzose, kusanganisa uye kubvisa mumiririri kunogona kuderedza zvakanyanya kushandiswa kwemvura kwekongiri musanganiswa uye kuderedza mvura simende reshiyo yekongiri uye kugadzirisa simba uye kugadzikana kwekongiri yakasimbiswa.. Kana pasi pemamiriro akafanana ekugadzirisa kwekongiri uye simba, kuwedzera mvura yekudzikisa mvura kunogona kuderedza chikamu chesimende kuitira kuchengetedza simende. Zvisinei, kune zvakare mamwe matambudziko mukushandiswa kwe superplasticizer mukongiri. Semuyenzaniso, apo iyo yakawanda ye superplasticizer ions iri anionic surfactants, ikoko kucharatidza zvimwe zvinhu zvakaita se lignin sulfonate, naphthalene sulfonate formaldehyde polymer, etc..
Nzira yekugadzira mvura inoderedza agent?
Kushandisa methyl naphthalene uye sulfur trioxide sezvinhu zvakabikwa, kuburikidza ne sulfation, condensation, neutralization uye mamwe maitiro, pakupedzisira kuburikidza nekuomesa chigadzirwa.
Matambudziko akajairika ekupomba kongiri: mhedzisiro yemvura inodzikisa mumiririri pamvura inobuda ropa!
Maererano nemaitiro echiito chemvura-inoderedza agent, polar mamorekuru adsorb akatenderedza simende zvimedu, kuita kuti zvidimbu zvidzinge, kuderedza flocculation, kuburitsa mvura yakavharwa nesamende zvidimbu, uye kutetepa iyo adsorbed yemvura layer pamusoro pezvimedu zvesimende, kuderedza zvakanyanya mvura yekunyorova inodiwa. Maererano nemuchina uyu, iyo inoderedza mvura inogona kuwedzera huwandu hwemvura yemahara mukrete nyowani uye kuwedzera kubuda kwemvura. Asi nerumwe rutivi, nekuda kwekudzikisa mvura kwemugadziri wekudzikisa mvura, mvura inosanganiswa inodiwa kune kongiri ine dhigirii rakafanana rekudonha inoderedza zvakanyanya mvura, kuitira kuti kongiri ibvise mvura yemahara kuderedza mvura. Mamiriro ekupedzisira ekubuda ropa anoenderana nekuti ibasa ripi rinotonga.
Iko kuchinjika kwema admixtures uye simenti kunokanganisawo kubuda ropa kwekongiri.
Ndeapi makuru ekutsvaga nzira dzekongiri yekudzikisa mvura mune ramangwana?
(1) Kugadzirwa kwezvinhu zvinoderedza mvura zvinogona kukwidziridzwa zvakanyanya kugadzirwa. Kuburikidza nekusarudzwa kwezvinhu zvekugadzira uye shanduko yekugadzira tekinoroji, iyo molecular chimiro chekudzikisa mvura inogadziriswa kuvandudza kuchinjika pakati pemvura inoderedza uye simende, kuitira kuwedzera mhedzisiro yemvura inoderedza.
(2) Zviviri kana kupfuura zvepamusoro-zvinoita zvinoderedza mvura zvinofanirwa kuve zvakasanganiswa zvakagadzirirwa mune imwe chikamu, kuitira kuti uchinje kushanda kwechikamu chimwe nechimwe panguva imwe chete uye kuunza kurongeka kwemukati kuburitsa chimiro chepamusoro.
(3) Kubva kudivi rekugadzirwa kwepolymer kweiyo nyowani inoshanda yekudzikisa mvura, zvizere optimize kongiri simba uye kusimba, etc, kuitira kuderedza mari yekugadzira.
Cie-China.org ndiyo inotungamira furo kongiri yekuwedzera inopa inopa kongiri inopupuma mumiriri, superplasticizer,foam kongiri simba rekusimudzira kune lightweight kongiri, CLC inovhara. Kana uri kutsvaga superplasticizer, ndapota inzwa wakasununguka taura nesu.
