1. Iyo polycarboxylic acid-based high-performance water-reducation agent yakasiyana neaphthalene-based high-performance high-performance-reducation agent mune izvozvo:
Yokutanga ndeyekusiyana-siyana uye kugadziriswa kwechimiro che molecular; chechipiri ndechekuwedzera kuisa pfungwa nekuvandudza zvakanakira zvemhando yepamusoro yekudzikisa mvura, uye kuwana girinhi uye isina kusvibiswa-isina maitiro ekugadzira.
Kubva pamaitiro echiito, chimiro chemolecular yepolycarboxylic acid inoderedza mvura mumiririri ine muzinga. Iyo yakasimba polar anionic "anchoring" boka mumaketani makuru rinoshandiswa adsorb pane zvimedu zvesimende. Muzinga wekunze-unowedzera unotsigirwa nemacheni akawanda emapazi. Chimiro chezino chinopa yakakwana nzvimbo yekuronga mhedzisiro yekuwedzera kupararira kwemasimende zvimedu. Kuenzaniswa nemagetsi ekudzoreredza kwekaviri yemagetsi layer ye naphthalene-based water reducing agents, iyo steric chipingamupinyi chinochengeta kupararira kwenguva yakareba.
Nekushandura zvakakodzera chimiro chemuzinga wepolycarboxylate inoderedza mvura uye nekushandura zvakakodzera kuwanda uye kureba kwemaketani ekumativi, mvura yakakwirira-inoderedza uye yakakwirira-yekutanga-simba-inoderedza mvura inokodzera zvikamu zvakagara zvakagadzirirwa inogona kuwanikwa.
Polycarboxylic acid-yakavakirwa mvura-inoderedza maajenti anogona kugadziridzwa uye kushandurwa zvinoenderana nezvinodiwa kuti uwane chinangwa chekuchinja mashandiro, pane kushandisa nyore musanganiswa wekugadzirisa. Zvichienderana nekunzwisisa uku, zvinogona kutikurudzira kuvandudza tekinoroji yedu yekushandisa mune ramangwana.
2. Kuchinjika kwepolycarboxylic acid-yakavakirwa mvura yekudzikisa maajenti kune simende zvinhu:
Mhando dzakasiyana dzesimende dzine mapoinzi akasiyana-siyana epolycarboxylic acid-based superplasticizers, saka zvakakosha kuti uwane nzvimbo dzekuzadza dzemasimende akasiyana. Zvisinei, kana mushandisi akati 1.0% chete inotenderwa kuwedzerwa, kana simende yakasarudzwa isingachinjiki pachiyero ichi, zvichanetsa kune admixture provider kuti aibate, uye nzira yekubatanidza inowanzoita zvishoma.
Madota ekutanga ane maitiro akanaka, nepo yechipiri-level uye yechitatu-level madota kazhinji haana kukodzera. Panguva ino, kunyange kana huwandu hwepolycarboxylic acid huchiwedzerwa, mhedzisiro yacho haisi pachena. Kazhinji kana imwe simende kana dota renhunzi riine hurombo hwekuchinjika kune zvakasanganiswa, uye hausati wanyatsogutsikana kana wachinja kune imwe musanganiswa, ungazopedzisira watsiva simende.
3.Dambudziko remukati mevhu mujecha:
Kana madhaka ejecha akakwira, chiyero chekudzikisa mvura yepolycarboxylate-based water-reducing agent ichaderedzwa zvakanyanya. Kushandiswa kwenaphthalene-based-water-reducing agents kunowanzogadziriswa nekuwedzera dhigirii, nepo polycarboxylic acid-based-based-reducing agents haishanduki zvakanyanya kana chiyero ichiwedzerwa. Muzviitiko zvakawanda, kana mvura isati yasvika padanho rinodiwa, kongiri yakatanga kubuda ropa. Panguva ino, mhedzisiro yejecha rekugadzirisa chiyero, kuwedzera mhepo yemukati kana kuwedzera thickener hakuzove kwakanyanya kunaka. Nzira yakanakisisa ndeyokuderedza dhaka.
