Mechanism yekuita yemvura inodzikisa agent

Mvura inoderedza maajenti, anozivikanwawo semaplasticizers, anowedzera anoshandiswa mukongiri uye zvimwe zvinhu simende kuderedza huwandu hwemvura inodiwa kuti uwane kushanda nesimba kwaunoda.Iyo nzira yekuita kwemvura inoderedza vamiririri inogona kutsanangurwa nemhedzisiro yavo pane zvemuviri zvimiro zvecementitious zvinhu.

Mvura inoderedza maajenti anoshanda nekushambadza pamusoro pezvikamu zvesimende uye nekuchinja machaji emagetsi pazvimedu.Izvi zvinoderedza masimba anosemesa pakati pezvimedu, zvichivabvumira kurongedza pamwechete zvakasimba.Nekuda kweizvozvo, nzvimbo dzisina chinhu pakati pezvikamu zvinodzikiswa, uye mvura inodiwa kuzadza nzvimbo idzodzo inodzikira.

Kushandiswa kwemvura yekudzikisa mvura kunogonawo kuvandudza kushanda kwekongiri kana simenti, zvichiita kuti zvive nyore kubata uye kuisa.Izvi zvinokonzerwa nekuderedza viscosity yemusanganiswa, iyo inobvumira kuvandudzwa kwekuyerera uye kubatanidzwa.

Mvura inoderedza mishonga inogona kuiswa muzvikamu zviviri zvikuru: lignosulfonates uye synthetic polymers.Lignosulfonates inotorwa kubva muhuni pulp uye inowanzoshandiswa mune yakaderera kusvika pakati nepakati simba kongiri.Synthetic polymers anogadzirwa kubva kumakemikari uye anogona kupa kudzikiswa kukuru kwemvura inodiwa uye yakagadziridzwa kushanda, ichiita kuti ive yakakodzera kushandiswa mune yakakwirira-inoshanda kongiri.

Muchidimbu, maitiro echiito chemvura ekudzikisa maajenti anosanganisira adsorption pane zvimedu zvesimende uye kushandura machaji emagetsi pane zvimedu.Izvi zvinoderedza masimba anosemesa pakati pezvimedu uye zvinozvibvumira kurongedza pamwechete zvakasimba, kuderedza nzvimbo dzisina chinhu uye kuderedza huwandu hwemvura inodiwa.Kushandiswa kwemvura yekudzikisa mvura kunogonawo kuvandudza kushanda kwekongiri kana simenti, zvichiita kuti zvive nyore kubata uye kuisa.
