Ndeapi marudzi anoderedza mvura uye ndeapi maitiro avo?

Vanoderedza mvura, vanozivikanwawo semaplasticizers kana superplasticizers, makemikari ekuwedzera anoshandiswa mukongiri uye musanganiswa wedhaka kuvandudza kushanda, kuderedza zviri mukati memvura, uye kuwedzera kushanda kwechinhu. Kune marudzi akati wandei evamiririri vanoderedza mvura, imwe neimwe iine maitiro ayo uye mashandisiro ayo. Heano mamwe marudzi akajairika:

1. Lignosulfonates: Lignosulfonates inotorwa kubva muhuni hwehuni uye ndeimwe yemhando dzekare dzemvura-kuderedza vamiririri. Iwo anowanzo shandiswa mumisanganiswa yekongiri kuvandudza kushanda uye kuderedza mvura yemukati uchichengetedza simba rakakwana. Lignosulfonates inodhura-inoshanda uye inoenderana nemhando dzakasiyana dzesimende.
2. Naphthalene Sulfonates: Naphthalene sulfonate-based water reducers inoshanda zvakanyanya mukuderedza mvura yemukati mukongiri musanganiswa uchivandudza kuyerera uye kushanda. Vanonyanya kukodzera kubudisa kongiri yakakwirira-yakadzika nemvura-kusvika-simenti ratios. Naphthalene sulfonates inogonawo kubatsira kuderedza dambudziko rekuparadzanisa uye kubuda ropa mukrete.
3. Melamine Sulfonates: Melamine-based water reducers inopa yepamusoro-yekudzikisa mvura zvivakwa zvichienzaniswa ne lignosulfonates uye naphthalene sulfonates. Ivo vanopa yakanakisa kushanda, yakakwira simba rekutanga, uye yakagadziridzwa kusimba mumakongiri musanganiswa. Melamine sulfonates anowanzo shandiswa mune yakakwirira-inoshanda kongiri kunyorera senge precast uye prestressed kongiri.
4. Polycarboxylate Ethers (PCEs): Polycarboxylate ethers chizvarwa chitsva chevamiririri vanoderedza mvura vanozivikanwa nekushanda kwavo kwepamusoro uye kushandiswa kwakasiyana-siyana. Vanogona kuderedza zvakanyanya mvura yemukati mumisanganiswa yekongiri uku vachichengetedza kuyerera uye kushanda kwenguva yakareba. MaPCE anopa kuenderana kwakanyanya nemhando dzakasiyana dzesimende uye zvinosanganiswa uye anowanzo shandiswa mukuzvibatanidza kongiri (SCC) uye yakakwirira-performance kongiri (HPC) application.
5. Combination Admixtures: Mamwe maajenti ekudzikisa mvura anogadzirwa semusanganiswa wemusanganiswa, izvo zvinogona kusanganisira musanganiswa weakasiyana makemikari makomisheni kuti azadzise zvinangwa zvekuita. Izvi zvinosanganiswa zvinogona kupa synergistic mhedzisiro, senge yakagadziridzwa slump kuchengetedza, kuwedzera simba rekuvandudza, kana kuderedzwa kwemhepo kupinza.

Hunhu hwevamiririri vanodzikisa mvura hunogona kusanganisira:

• Kuderedzwa kweMvura: Basa rekutanga revanoderedza mvura nderokudzikisa huwandu hwemvura inosanganiswa inodiwa kuti iwane kuenderana kunodiwa kwekongiri kana dhaka musanganiswa. Izvi zvinobatsira kuvandudza simba, kusimba, uye kushanda kwechinyorwa uku uchideredza njodzi yekuparadzaniswa uye kubuda ropa.
• Kushanda: Vamiririri vanoderedza mvura vanovandudza kushanda uye kuyerera kwekongiri yakasanganiswa, zvichiita kuti zvive nyore kuiswa uye kubatanidzwa pasina kupa simba kana kubatana. Ivo vanobatsira kuve nechokwadi chekugovaniswa kwakafanana kweaggregates uye cementitious zvinhu mukati memusanganiswa.
• Kugarisana: Vanoderedza mvura vamiririri vanofanirwa kuenderana nezvimwe zvinosanganiswa uye zvinowedzera zvinoshandiswa mumisanganiswa yekongiri, senge air-entraining agents, set retarders, uye accelerators. Kuenderana kunovimbisa kuti inodiwa zvivakwa uye kuita kwekongiri kunowanikwa pasina kushata maitiro kana mhedzisiro.
• Chiyero cheDosage: Kushanda kwevamiririri vanodzikisa mvura kunoenderana nehuwandu hweyero, iyo inowanzo ratidzwa sechikamu chesementitious zvinhu zvirimo mumusanganiswa. Optimal dosage rates inogona kusiyana zvichienderana nezvinhu zvakaita sesimende rudzi, aggregate hunhu, ambient tembiricha, uye inodiwa kongiri zvivakwa.
• Kuisa Nguva: Vamwe vamiririri vanoderedza mvura vanogona kukanganisa nguva yekumisikidzwa kwekongiri musanganiswa, kungave kukurumidza kana kudzoreredza nguva yekutanga uye yekupedzisira. Yakafanira dosage uye kusarudzwa kwezvinoderedza mvura zvinodikanwa kuti uwane inodiwa yekumisikidza maitiro kune chaiwo mashandisirwo ekuvaka.
• Mutengo uye Kuita: Mafungiro akadai sekudhura-kushanda, zvinodiwa pakuita, uye maratidziro epurojekiti anoita basa rakakosha pakusarudza mumiriri akakodzera wekudzikisa mvura kune imwe application. Izvo zvakakosha kuti uongorore mabhenefiti uye zvipimo zvemhando dzakasiyana dzezvinoderedza mvura kuti uone sarudzo yakanyatsokodzera kune zvinodiwa neprojekiti.

vamiririri vanodzikisa mvura vanoita basa rakakosha mukugadzirisa mashandiro uye kusimba kwekongiri nedhaka musanganiswa, zvichibvumira maitiro ekuvaka ane hunyanzvi uye kuvandudzwa kwemhando yezvivakwa zvakapedzwa.
