1.Kushanda kune simende:
Kuumbwa kwesimende uye simenti zvinhu zvakaoma uye zvinoshanduka.Kubva pakuona kweadsorption-dispersion mechanism, hazvibviri kuwana mvura inoderedza mumiririri inokodzera zvose.Nyangwepolycarboxylate mvura-yekudzikisa mumiririri ine yakafara kuchinjika kupfuura naphthalene akatevedzana, ichiri Kugona kusagona kuchinjika kune mamwe simende.Uku kuchinjika kunonyanya kuratidzwa mu: kuderedzwa kwehuwandu hwekudzikisa mvura uye kuwedzera kurasikirwa kwekudonha.Kunyangwe iri simende imwe chete, mhedzisiro yemvura inodzikisa mumiriri ichave yakasiyana kana bhora rikagayiwa kune fineness yakasiyana.
Chiitiko:Chiteshi chekusanganisa chinoshandisa imwe P-042.5R simende munzvimbo yemunharaunda kuti ipe C50 kongiri kunzvimbo yekuvaka.Inoshandisa apolycarboxylatesuperplasticizermvura-kuderedza mumiririri.Paunenge uchiita kongiri musanganiswa reshiyo, zvinoonekwa kuti uwandu mvura-kuderedza mumiririri anoshandiswa simende ndiyo Iri zvishoma kupfuura mamwe simende, asi panguva chaiyo kusanganisa, kudonha kwefekitari kongiri musanganiswa akanga nemaziso kuyerwa kuva 21Omm.Pandakaenda kunzvimbo yaivaka kuti ndiburutse rori yepombi yekongiri, ndakaona kuti rori yacho yaisagona kuburutsa kongiri.Ndakazivisa fekitari kuti itumire dhiramu.Mushure mokunge mvura inoderedza mvura yakawedzerwa uye yakasanganiswa, kudonha kwekuona kwaiva 160mm, iyo yakanyatsosangana nezvinodiwa zvekupomba.Zvisinei, pakuburutsa zvinhu, zvairatidza kuti yaisakwanisa kuburutswa.Rori rekongiri rakadzorerwa pakarepo kufekitari, uye mvura zhinji nechitsama chiduku chokuderedza chakawedzerwa.Iyo liquid agent haina kuburitswa uye yakada kusimba mumixer rori.
Chikonzero chekuongorora:Hatina kuomerera pakuitisa bvunzo dzekuchinjika nemamixtures pabatch yega yega simende tisati tavhura.
Kudzivirira:Ita muyedzo wekubatanidza nereshiyo yemusanganiswa wekuvaka pabhechi rega rega resimende usati wavhura.Sarudza zvakasanganiswa zvakakodzera."Gangue" semusanganiswa we simenti haina kugadzikana kupolycarboxylate superplasticizerzvinoderedza mvura, saka dzivisa kuishandisa.
2.Sensitivity kune kushandiswa kwemvura
Nekuda kwekushandiswa kwepolycarboxylate mvura-inoderedza mumiririri, kushandiswa kwemvura kwekrete kunoderedzwa zvikuru.Kushandiswa kwemvura kwekongiri imwe chete kunowanzoita 130-165kg;muyero wemvura-simende ndeye 0.3-0.4, kana kunyange isingasviki 0.3.Panyaya yekushandiswa kwemvura yakaderera, kuchinja kwekuwedzera kwemvura kunogona kukonzera shanduko huru mukudonha, zvichiita kuti musanganiswa wekongiri uwedzere kudonha uye kubuda ropa.
Chiitiko:Chiteshi chekusanganisa chinoshandisa P-032.5R simende kubva kune imwe fekitori simende kugadzirira C30 kongiri.Kondirakiti inoda kuti kudonhera kunzvimbo yekuvaka iri 150mm:t30mm.Kana kongiri yabva mufekitori, kuyerwa kudonha kuri 180mm.Mushure mokuendeswa kunzvimbo yekuvaka, kongiri inoyerwa panzvimbo yekuvaka.Kudonha kwacho kwaive 21Omm, uye marori maviri ekongiri akadzoserwa achitevedzana.Pakudzoserwa kufekitori, zvakasimbiswa kuti kudonha kwacho kwanga kuchiri 21Omm, uye kwaive nekubuda ropa uye delamination.
Chikonzero:Simende iyi ine zvakanaka kuchinjika kune ichi chinoderedza mvura, uye huwandu hwemvura inodzikisa mvura yakakura zvishoma.Nguva yekusanganiswa haina kukwana, uye kudonha kwekrete kana uchisiya muchina hakusi iko kudonha kwechokwadi nekuda kwenguva pfupi yekusanganisa.
Kudzivirira:Zvesimende zvinonzwa nepimo yepolycarboxylatesuperplasticizermvura-inoderedza admixtures, iyo dosage ye admixtures inofanirwa kuve yakakodzera uye kuyerwa kwechiyero kunofanira kunge kwakakwira.Nyatsowedzera nguva yekusanganisa.Kunyangwe neine mapatya-shaft yakamanikidzwa musanganisi, nguva yekusanganisa haifanirwe kunge iri pasi pemakumi mana masekonzi, zviri nani kupfuura masekonzi makumi matanhatu.
