Mvura inodzikisira musanganiswa wekongiri unogona kuderedza huwandu hwekusanganisa mvura uchichengetedza kudonha kwekongiri. Vazhinji vavo vane anionic surfactants. Mushure mekuwedzera kune musanganiswa wekrete, ine simba rekuparadzira pane zvimedu zvesamende, izvo zvinogona kuvandudza kushanda kwayo, kuderedza kushandiswa kwemvura yeyuniti, nekuvandudza fluidity yemusanganiswa wekrete; kana kuderedza kushandiswa kwesemende uye kuchengetedza simenti.
Maererano nechitarisiko:
Yakakamurwa kuva mvura-based uye powder-based. Iyo yakasimba yemvura-yakavakirwa kazhinji 10%, 20%, 40% (inozivikanwawo sedoro raamai), 50%, uye iyo yakasimba yehupfu inowanzoita 98%.
Zvinoenderana nekugona kuderedza mvura uye kuwedzera simba:
Yakakamurwa kuita yakajairwa mvura inoderedza (inozivikanwawo seplasticizer, ine mwero wekudzikisa mvura isingasviki 8%, inomiririrwa ne lignin sulfonates), yakakwira-inoshanda mvura inoderedza (inozivikanwawo se superplasticizer, ine mwero wekudzikisa mvura isingasviki. kupfuura 14%, kusanganisira naphthalene series, melamine series, aminosulfonate series, aliphatic series, etc.) uye inoderedza mvura yepamusoro-yepamusoro (chiyero chekudzikisa mvura haisi pasi pe25%, inomiririrwa ne polycarboxylic acid series water reducer), uye yakakamurwa kuva mhando yesimba rekutanga, mhando yemhando uye inononoka yekumisikidza mhando zvichiteerana.
Zvinoenderana neyakagadzirwa zvinhu:
Lignin sulfonates, polycyclic inonhuwira munyu, mvura-soluble resin sulfonates, naphthalene-based high-effective water reducers, aliphatic high-effective reducer water, amino high-effective water reducers, polycarboxylate high-performance water reducers, nezvimwewo.
Zvinoenderana nemakemikari:
Lignin sulfonate zvinoderedza mvura, naphthalene-based high-effective water reducers, melamine-based high-effective water reducers, aminosulfonate-based high-effective water reducers, fatty acid-based high-effective water reducers, polycarboxylate-based high-effective water reducers. .
Basa remvura inoderedza:
1.Pasina kushandura chiyero chezvinhu zvakasiyana-siyana zvakasvibirira (kunze kwesamende) uye simba rekrete, huwandu hwesimenti hunogona kuderedzwa.
2.Pasina kushandura chiyero chezvinhu zvakasiyana-siyana (kunze kwemvura) uye kudonha kwekrete, kuderedza kuwanda kwemvura kunogona kuvandudza zvikuru simba rekrete.
3.Pasina kushandura chiyero chezvinhu zvakasiyana-siyana, rheology uye plastiki yekrete inogona kuvandudzwa zvikuru, kuitira kuti kuvaka kwekrete kunogona kuitwa negiravhiti, kupomba, pasina kudengenyeka, nezvimwewo, kuwedzera kukurumidza kwekuvaka uye kuderedza kushandiswa kwesimba rekuvaka. .
4.Kuwedzera-yakakwirira-yakanyatsogadzirisa mvura inoderedza kune kongiri inogona kuwedzera hupenyu hwekongiri nekanopfuura kaviri, ndiko kuti, kuwedzera hupenyu hwesevhisi hwechivakwa nekanopfuura kaviri.
5.Deredzai shrinkage rate yekrete solidification uye kudzivirira kuputika muzvikamu zvekrete; kuvandudza kupikisa kwechando, iyo inobatsira pakuvaka kwechando.
Mechanism yekuita yemvura inoderedza:
·Kupararira
·Kuzora
·Steric chipingamupinyi
·Kunononoka-kuburitsa mhedzisiro yeakabatanidzwa copolymer parutivi cheni
