7. Simba rekusanganisa nguva uye kusanganisa kumhanya

Nguva yekusanganisa ine zvakananga zvakananga pane zvemukati zvekongiri uye kupatsanurana kwekongiri yekongiri pane kongiri, uye zvisina kunangana zvinokonzeresa, michina yekubatira uye kusimba kwekongiri. Kana iyo musanganiswa unomhanya zvakanyanya, zviri nyore kukuvadza iyo colidal chimiro muchikamu uye iyo mbiri yemagetsi emagetsi membrane pamusoro peiyo simenti time, iyo ichazokanganisa nguva yekuisa uye kutsvedza kwekongiri kune yakakura. Iko kusanganisa kumhanya kunoda kudzorwa mukati memaminitsi 1.5-3. Kana iyo nzira yakaoma yekusanganisa inoshandiswa, kongiri inogona kusanganiswa zvakanyanya nekushandisa iyo kuderedza kwemvura zvine musoro. Kana mhinduro yacho ichida kuwedzerwa, iyo mvura inoda kubviswa kubva mukusanganiswa panguva yekugadziriswa kwemvura kugovera kuti ive nechokwadi chekusimbisa kwemvura-simende. Kuti vave nechokwadi chekutsvedza kwekongiri uye kupa zvizere kutamba kune chinzvimbo chekubhadhara kwemvura, iyo nzira yekusanganisa-yekusanganisa inogona kushandiswa zvakananga. Yakasiyana neyakanyanya-mukana wekudzvanywa mvura yekudzoreredza yekuwedzera nzira, iko kusevenzesa kwekongiri kunogona kuvezwa nekushandisa nzira yekutumira-kusanganisa zvine musoro zvine musoro. Kana rori yemununuri inodiwa kutakurwa kongiri, kuderedza kwemvura kunogona kuwedzerwa kune iyo musanganiswa mota 2 usati watema nekumhanyisa kuwanda kwemusanganiswa wemuvhimi uye kuvandudza maitiro ekutsvagira.

8. Chikonzero chekushambadzira tembiricha uye humidity

Iyo yekuisa nguva, kuomesa kumhanya uye kusimba kwekutanga kwemusanganiswa wakanangana zvakananga zvinoenderana nekuporesa tembiricha. Pashure pokuwedzera mvura kugovera mvura, chiitiko ichi chiri pachena, uye mhedzisiro yacho ichave yakakosha kana nguva yekuisa iri pazasi 20 degrees celsius. Kazhinji, yakakwira tembiricha, iyo inokurumidza hyment hydration chiyero, uye nekukurumidza iyo yekubuda kwemutengi yekongiri ichave. Mvura yemahara mukati mekongiri icharamba ichiwedzera kuwedzerwa kune iyo kongiri pamusoro kuburikidza neCapillary, inoenderera mberi ichikurudzira hydration mhedzisiro yeiyo simende. Mvura yemahara mumakongiri iri yakachekwa uye yakaderedzwa, iyo inowedzera kurasikirwa kwekutsvedza kwekongiri. Uye zvakare, kudzoreredzwa kweimwe konganzuru yekongiri kuchadzikiswa zvakanyanya pamusoro pemakore makumi matatu celsius. Naizvozvo, kana zvichidikanwa kushanda mumamiriro ekunze epamhepo, zvinodikanwa kuti uwedzere kuwedzera huwandu hwekongiri yekubvumirana nekudzivirira kunyatso dzivirira kuitika kwemvura yekubuda kwemvura. Wood calcium ine imwe inononoka kuisa midziyo. Inogona chete kuve neimwe mhando yesimba rerudzi mushure mekudurura kwenguva yakareba. Munguva yekugadzirisa basa, zvinodikanwa kuti uwedzere nguva yekumisa nguva yakakwana uye maitiro esainzi iyo dosage. Zvikasadaro, kongiri inowanzo kuve yakakomba marara, kusununguka kwepasi uye kushusha panguva yekushandisa. Mukuita kwekushandisa yakakwira-kugona kwemvura kuderedza, nekuda kwekunyora kwemhepo kupindirana, iyo inononoka kugadzika haigoni kuvimbiswa, uye yakareba nzvimbo yekumira haina kudiwa panguva yekuporesa steam yekuporesa. Naizvozvo, mukuwedzera kuwedzerwa muAffinture, basa rekugadzirisa rakakodzera rinofanira kuitwa nokungwarira kudzivirira kubuda kwakakura kwemvura panguva yekugadzirisa maitiro.

9. SIMENT yekuchengetedza nguva

Mumamiriro ezvinhu akajairwa, nguva pfupi yekuchengetedza nzvimbo yekuchengetera, ichaonekwa mubereki, uye zvakanyanya kunaka kwesimbiso yesimendi ichave. Chissimusi chitsemhemberero, iyo yakasimba iyo mhosva yakanaka, uye iyo yakawanda yeonic surfachers inoyemurika. Zvemasumbidzo iyo ichangobva kuongororwa, iyo yekudzora kwayo mwero yakaderera uye kurasikirwa kwekutsanya kutsanya. Zvemasimendi ane nguva yakareba yekuchengetedza, matambudziko aya anogona kudzivirirwa.

10. Alkali zviremerwa mu cement

Iyo alkali yezvinyorwa zvakare ine zvakananga zvakaringana pane shanduko yeiyo simende uye mvura kuderedza. Sezvo zvaAlkali zvemukati wesimende zvinowedzera, kupokana kwesimbe kuchawedzera. Kana iyo Alkali icent inodarika imwe huwandu, ichave neyakanyanya kukanganisika pane iyo nguva yekuisa uye kutsvedza kwesimendi. Uye zvakare, chimiro cheAlkali mumumumende zvakare chine zvakananga zvakananga kukanganisa pane iyo yekushandisa mhedzisiro yemvura inobhadhara mvura. Mumamiriro ezvinhu akajairika, kana alkali iripo muchimiro cheSulfate, zvayo zvinogadziriswa nemvura zvakaderera pane izvo zviri muchimiro che hydroxide.

11. Gypsum in coment

Nekuwedzera siment gypsum kuti isimbe, hydration yemasimende inogona kunonoka kwazvo, uye kuyamadza kwakananga kunogona kudzivirirwa, nekudaro kunovandudza kushanda kweiyo simende uye kuderedza mvura. Zvinoenderana nehuwandu hukuru hwezvidzidzo, mushure mekuwedzera imwe huwandu hwe gypsum kusvika simende, iyo adsorption yekudzora mvura pa coment mineral c3a inogona kuderedzwa zvino. Izvi zvinonyanya kuitika nekuti gypsum uye c3a zvinogona kuita kuti uvhara zvakananga pamusoro peC3A, iyo inogona kupedza simba reC3A particles pane mvura kuderedza mvura. Mhando dzakasiyana dzeGypsum ine akasiyana dissolution mitengo uye midziyo. Type uye zvemukati zveComent Gypsum vane zvakananga zvakananga kukanganisa pane shanduko pakati peiyo simende uye mvura kuderedza. Iyo Pore Fluid Sulfate muComent Consrete inonyanya Kubvira kubva kuSulfate yakaumbwa neSiltirate center Iyo sulfate ion in gypsum kazhinji inochinja zvakasiyana panguva yekukuya. Kana tembiricha yekugeza maitiro yakakwirira, iyo dhizaini gypsum ichave yakadzika marara uye fomu hemhydrate gypsum. Kana tembiricha iri mukati megayo yakanyanya kukwirira, huwandu hwakawanda hweHeMiytrate gypsum ichaumbwa mune izvi, izvo zvinozopedzisira zvaunza kuitika kwesimendi pseudo-kurongedza. Zvemasimendi ane mashoma alkaline Sulfate zvikamu, pasi peiyo Adsorption yeSulfonic acid-yakavakirwa mvura inoderedza, ichakonzera kukonzeresa kongiri kuti idonhedze nekukurumidza. Kana iyo Suluble Sulfate Zvemukati inowedzera, iyo adsorption yekubudirira kwemvura yakakwira inodzikisira icharatidza Quasi-mutsara pasi pasi.

12. SEment Kukuya AIDS

Iyo simende yekukuya inogona kuvandudzwa kwazvo nekushandisa simende yekukuya zvinhu zvine musoro. Mukuita kwekugadzirwa kwesimendi mumakambani mazhinji ekunze ekunze, ekukuya AIDS anowanzoshandiswa muhuwandu hukuru. Mumakore achangopfuura, mushure mekushandiswa kwezvinyorwa zvitsva zvechinyorwa munyika yangu, izvo zvinodiwa nesimba uye zvakajeka zveSimende zvakavandudzwa, izvo zvakaisa zvinodiwa zvepamusoro zvekushandisa rubatsiro rwekukuya. Parizvino, kune akawanda marudzi ezvemument anoyevedza AIDS, uye nhamba yekukweva yekukuvara vabatsiri munyika yangu iri kuratidzawo maitiro ekuwedzera kuwanda. Various cement grinding aid manufacturers have continuously invested in the research and development of economical, efficient and easy-to-use grinding aids. Nekudaro, vamwe vagadziri vekuchera vanobhadhara zvakanyanya kutarisisa kwemitengo yekugadzira uye kuisa mari zvishoma mukushandiswa kwekunyepedzera, yemabhawa engoro mukati kongiri. ② Iko kushandiswa kwekutapira kweLignin Sulfonate kunotungamira padambudziko rakakura kusingakwanisi kupindirana pakati pe simende uye kongiri admixture. Kuti ③ kuitira kuti udzikise zvinobudirira mari yekugadzira, huwandu hwakawanda hwemaindasitiri anowanzoshandiswa, ayo ane simba rakanyanya kujaira kongiri. Muchirongwa chazvino chekugadzira kongiri, iyo Alkali uye chloride ion yeCym Mukushandiswa kwekukwevera AIDS, kusimba kwesimende hakugone kubayirwa. Kuumbwa kwekukwevera AIDS kwakanyanyisa kuoma. Chete nekushandisa kugeda AIDS zvine chikonzero kunogona kuita kongiri kuvimbiswa. Munguva yekugadzira maitiro, yekukuvara rubatsiro vanofanirwa kuve nekunyatsonzwisisa kwekunzwisisa kwekambani yekugezesa, uye tenzi mhando dzekukwevera AIDS uye simenti tringer.

13. Kuvaka musanganiswa ratio

Iyo yekuvaka musanganiswa ratio ndeyako yeinjiniya dhizaini dambudziko, asi ine zvakananga zvakaringana pakuenderana nekongiri yekubvumirana uye simende. Sekureva kwedata yakakodzera, kana jecha ratio yakanyanya, zviri nyore kukonzera iyo fluidity yemusanganiswa wekongiri kuderera, uye kurasikirwa kwekutsvedza kwakakura kwazvo. Mukuwedzera, chimiro, mvura yekubatwa nemabwe ematombo ari mumusanganiswa wemasanganiswa anozochinjawo, kuchengetwa kwemvura, kubatana uye kuumbwa kwekongiri kune imwe nhanho. Miedzo yakakodzera inoratidza kuti nekuderedza iyo yemvura-simende rekongiri inogona kuvandudzwa kune imwe nhanho. Pasi pemamiriro ezvinhu emvura akakwana, zvinhu zvakasiyana-siyana zve congment congment zvinogona kuzoshandiswa zvizere, zvekuti pfungwa dzayo dzive dzakanyatsogadziriswa, kusunganidzwa kwezviitiko kunogona kuvimbiswa, uye kuwirirana kwechiitiko uye simende kunogona kuvandudzwa.
