Yakakwirira-Kuita Mvura-Kuderedza Agent Application
1. Molecular Structure Customization
Iyo polycarboxylate yekudzikisa mvura mumiriri ine divi recheni density ye ≥1.2 per nm² inosarudzwa. Iyo steric hindrance mhedzisiro inogona kuderedza kukuvadzwa kweiyo adsorption layer inokonzerwa nekupisa kwakanyanya. Kana yawedzerwa ne 30% fly ash admixture, chiyero chekudzikisa mvura chinogona kusvika 35% -40%, nekurasikirwa kweawa imwe chete kuderera kwepasi pe10%. Iyi yepamusoro-side cheni density polycarboxylate inodzikisa mvura inoumba yakakora adsorption layer pamusoro pemasimende, ichipa yakasimba steric repulsion, ichibvumira masimende kuchengetedza nzvimbo yakapararira zvakanaka kunyangwe munzvimbo dzine tembiricha. Uyezve, kuwedzererwa kwedota renhunzi hakungodzikisi sement kushandiswa uye kunoderedza kupisa kwe hydration, asi zvakare kunogadzira synergistic mhedzisiro neinoderedza mvura mumiriri, zvichiwedzera kuvandudza kushanda uye kusimba kwekongiri.

2. Slump-Kuchengetedza Synergistic TechnologyIko kuiswa kwemethyl allyl polyoxyethylene ether monomer inogadzira matatu-dimensional network chimiro. Munzvimbo inofananidzwa pa 50 ° C, yakasanganiswa nechikamu chekudzorera, kuwedzera kwekrete kunogona kuchengetedzwa pamusoro pe 650mm kwemaminitsi 120, kusangana nezvinodiwa zvekupomba kwezvivako zvepamusoro-soro. Iko kuunzwa kwemethyl allyl polyoxyethylene ether monomers inogadzirisa chimiro chemolecular yepolycarboxylate superplasticizer, ichigadzira matatu-dimensional network dhizaini inosimudzira kugona kwayo kuvharira uye kuparadzira masimende masimende. Munzvimbo dzepamusoro-tembiricha, chimiro ichi chinonyatso pikisa kukanganiswa kubva kune simenti hydration zvigadzirwa, kuchengetedza fluidity uye kudonha kwekongiri. Kana yakashandiswa pamwe chete nezvinodzoreredza zvikamu, inogona panguva imwe chete kunonoka simende hydration uye kuchengetedza kudonha, kusangana nezvinodiwa zvekuvaka kwekongiri yepamusoro, senge pakupomba kwepamusoro-soro.
