Superplasticizer mhedzisiro uye musimboti

Iyo yakakwirira-yepamusoro-inoshanda yekudzikisa mvura inogona kuvandudza zvakanyanya fluidity yekukurudzira slurry, kuitira kuti madhaka anopupuma asvike pakuzvigadzika muforoma, kuderedza kana kutoshaya chingwa. Inogona kuderedza zvakanyanya kushandiswa kwemvura uchichengeta kudonha kwekongiri, uye mvura inoderedza mumiririri inonziwo dispersant kana plasticizer. Ndiyo inonyanya kushandiswa musanganiswa.

Basa rekudzikisa mvura:

1. Deredza iyo solid-liquid interface simba remasimende zvimedu

2.Static repulsion

3.Spatial zvinosemesa simba

4. Lubrication maitiro e hydration film

Mvura inoderedza mumiririri musimboti:

Iyo chaiyo nzvimbo yesamende inowanzoita 350-400m2 / kg, uye saizi yechidimbu inodarika 90% zvesimende zvimedu zviri pakati pe 7-80 microns, inova yechikamu chehupfu hwakatsetseka. Yesimende-mvura system, pamusoro pezvikamu zvesimende uye hydrated simende zvimedu zvine polar zvishoma uye zvine simba re hydrophilicity.. Zvimedu zvesimende zvakakura zvine saizi chaiyo pamusoro pesimba (solid-liquid interface simba). To reduce the total heat on the surface solid-liquid, zvimedu zvesimende zvakanaka zvinowanzoita kudzika mu floc kudzikisa iyo interface simba reiyo system uye kuita iyo thermodynamic system.. Chengetedza kugadzikana. Panguva imwe, muchikamu chekutanga che simenti hydration, pamusoro peC3A particles inopomerwa zvakanaka, nepo nzvimbo dzeC3S neC2S zvidimbu zvichipomerwa zvakaipa. Iyo electrostatic kukwezva kwechaji yakanaka uye yakaipa inosimudzirawo kuumbwa kweiyo flocculation chimiro chemasimende zvimedu..

Kune nzira nhatu dzemvura mukongiri: mvura yemahara-inosungwa nemvura uye adsorbed mvura. Muchikamu chekutanga chekusanganisa simenti, kune mvura shoma inosungwa nemakemikari uye mvura yakashambadza, uye mvura yakasanganiswa inonyanya kuvepo muchimiro chemvura yemahara. Zvisinei, nekuda kweiyo flocculation chimiro chemasimende masimende, 10% -30% mvura yakashama ichaputirwa mariri, nokudaro kuderedza zvakanyanya fluidity yemusanganiswa wekrete. Basa rekutanga nderekuparadza flocculation chimiro chemasimende masimende, chengetai munzvimbo yakapararira, uye sunungura mvura yemahara mupakeji uye floc, nokudaro achivandudza fluidity yekongiri itsva.

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.
