Superplasticizer C-3. Plasticizers ngoba usimende slurries

Superplasticizer C-3 yaziwa nangokuthi "Superplast-Standard". It uba i okufakiwe for ukhonkolo kanye sisetshenziselwa izinto zokwenziwa organic okuyinto elakhiwe okusekelwe umkhiqizo esukela ukufingqa naphthalenesulfonic acid formaldehyde. Owenza okufakiwe ngokuvumelana GOST 24211-2003 futhi ibekwe njengoba amanzi ekunciphiseni plastifitsiruyusche-umbono.

kudingeka sisebenzise

Sebenzisa le okufakiwe ukwandisa ukuhamba ukhonkolo mass nodaka amamiksi a P5 ezingeni. Ngaphezu kwalokho, uma ungeza plasticizer, bekuyoba ukuqeda ematfuba i ukulahlekelwa ekuseni wamandla, okuyilokho, eqinisweni, esivela iningi superplasticizers. Kwezinye izimo, asikho isidingo ukushintsha isikhathi kulungiselelwa, wabe esesebenzisa okuningi plasticizer. Ukusetshenziswa Its kuyadingeka esimweni lapho kwakhiwa ezisindayo, ingxenyenamba amancane ukhonkolo engasindi. Ngaphezu kwalokho, lokhu okufakiwe, okuyinto akuphazamisi kulungiselelwa kwesikhathi, isetshenziswa esihambisana amasistimu usimende izinhlelo zokusebenza ezikhethekile.

Umthelela plasticizer phezu mix ukhonkolo

Superplasticizer C-3 emva kwalokho kunganciphisa ukusetshenziswa usimende ingxenye ku-20%, kusobala njengoba evelele kunazo zonke omuhle izinga idatha izithasiselo. Le nto ngcono kakhulu processability we ukhonkolo nodaka. Ngemva plasticizer kuyinto ingxenye yesixazululo, lona wamuva kuba lula kakhulu ukusebenza. Ngakho, kulula kakhulu isitayela, kuba sengathi eyohlobo ngaphezulu, awusebenzi yini sehlukane ukuze ngiphinde ubuqotho ezahlukene. Kalula isitayela iba ephakeme kunaleyo 30%.

Superplasticizer-3 kunomthelela yokulungiswa ukulahlekelwa ukuhamba sokuqanjwa ngokuhamba kwesikhathi. Ebusika, uma kukhona isidingo kuvuleke uwuveza obala ukufudumeza ukwelashwa. Ngemva kwalokho izinto ezichazwe kungalindeleka ukuthi umnotho wawo kakhulu ukunciphisa isikhathi sokwelashwa ezishisayo sokuqanjwa yokusakaza. Ngokunjalo ngemva solidification isakhiwo ozuza amandla ngcono futhi inikeza isikhathi isikhathi eside kunaleso ukhonkolo ngaphandle okufakiwe.

Superplasticizer C-3 inomthelela ushintsho kwamanzi kanye negesi permeability ngokhonkolo. Lezi zinombolo abangelutho. Futhi lapho zihlatshwa okushisa aphansi of izakhiwo zikakhonkolo libhekene ukuzinza okusezingeni eliphezulu. Ngaphezu kwalokho, ukhonkolo iba amelana zonke izinhlobo yabezindaba nolaka, ngenxa nje kuphela seal kodwa futhi kumiswa isakhiwo setshe usimende.

Uma lichaza ekwakheni ukhonkolo yasiphendula plasticizer, okuyinhloko ungaqiniseka ukuthi umphumela ayisivikelo design mayelana nokuqiniswa sensimbi kakhulu anda. A ukuziphatha concreting lapho Ukwakheka has a okufakiwe ekhethekile kungaba ngisho ebusika lapho lokushisa kuma ifinyelela inkomba -15 ° C.

Ukwehlisa isikhathi futhi ukushuba vibration izinqubo

Njengoba yaziwa, ngemva ethela ukhonkolo angena ikhambi formwork kudingeka, ngemisebenzi ubuchwepheshe, ukuthonya indlela yokwakheka ipuleti vibration. Isikhathi salesi ukuchayeka ingancishiswa kakhulu ngemva superplasticizer kuyinto C-3, ukulaya ekusetshenzisweni ozokwethulwa ngenzansi ikhambi. Ngaphezu ekunciphiseni vibration ukuchayeka isikhathi zingancishiswa futhi ngegalelo lako. Esinye isici esihle plasticizer wukuthi elisetshenziswa ukubunjwa ukhonkolo abakwazi kuphela inciphise aggregate kusilela krupnofraktsionnogo, kodwa futhi aluqede ngokuphelele ke. Buyisela lesi ingxenye kungaba ukhonkolo esihle.

Ikakhulukazi ukusetshenziswa "Superplast-Standard"

Superplasticizer C-3, ekusetshenzisweni imiyalelo kumele zihlolwe ngaphambi kokuba zisetshenziswe, inezici kakhulu ukuthi sewenze ndaba athandwa kakhulu kuleli ukwakhiwa yesimanje. Umenzi uncoma ukusetshenziswa i okufakiwe ezichazwe ethile umthamo umthamo kukhawulwe Inkomba kusuka 0.5 kuya 0.75% ngesisindo sezinti ingxenye usimende. Ukubala kwenziwa nsuku ezomile.

Uma ukhetha ukusebenzisa super plasticizers for ukhonkolo ke elamukelekile kubalulekile ukwethula izithako okufakiwe ku mix ukhonkolo. Lokhu kungenziwa ngokukhumula eyodwa yezindlela ekhona. Omunye kuhilela kwalokho ngesikhathi esisodwa plasticizer nalo lonke ivolumu uketshezi at ukuxuba. Isizathu sesibili indlela ehlanganisa ngokungeza plasticizer kusengaphambili ezihlangene mix ukhonkolo. Kulokhu, lo okufakiwe siqala ngala umthamo omkhulu wamanzi. I plasticizer angase engezwe emva kuhlangana mix ukhonkolo, kodwa kubalulekile ukucabangela umthamo wamanzi. Khetha noma iyiphi indlela eyodwa yokwazisa okufakiwe kungaba, kuye ngokuthi izidingo ukukhiqizwa, ubuchwepheshe esetshenziswa futhi ukunemba imishini metering.

Izici superplasticizer C-3

Plasticizers ngoba usimende izigqulo kukhiqizwa ngokuvumelana TU 5730-012-97474489-2010. Ngaphambi kokuba uqale ukusebenzisa kwabo, kubalulekile ukuba bajwayelane izici lobuchwepheshe izithasiselo. Ngakho, ngokubukeka kuba powder eyohlobo, ngokuvamile kufanele ibe nombala brown ukukhanya. okuqukethwe Water asendabeni akumele leqe 10%. Ngokuphathelene nomsebenzi hydrogen ion, lesi sibalo kumele ilingane 8.5 + 1.5, okuyinto leqiniso 2.5% isixazululo aqueous. Chloro, noma kunalokho, layo ingxenyenamba mass kumele singeqi sibalo 0.1%, okuyinto kuyiqiniso ngoba into isebujameni ezomile.

Uma uke waqala ukukhiqizwa tile, ungabese badinga plasticizer ngoba tile, yengezwe ekukhiqizeni ungqimba phezulu imikhiqizo.

Okufakiwe futhi isitoreji

Plasticizers amakhambi usimende kumele athuthelwa egcinwe ngokuvumelana nemithetho ethile kuphela. Ngakho, ngemva senqubo yokukhiqiza izidakamizwa is zahlanganiswa ku izikhwama ezenziwe polypropylene. Ngaphezu kwalokho, izikhwama kufanele abe liner polyethylene. Isisindo isikhwama ngasinye ezifana 25 kg. Gcina plasticiser kumele kube ngokukhethekile emaphaketheni yomenzi, kungenjalo ukwakheka angase maduzane ulahlekelwe eliphezulu ukusebenza kwabo futhi kuyoba langakufanelekela ukusetshenziswa ngokwengeziwe. Phakathi kwezinye izinto, lo kwalokho akufanele kwenziwe nje igcwele, kodwa futhi ibe ishede enompheme.
Kodwa ezokuthutha superplasticizer kungaba yisiphi ezokuthutha zilwane.

Incazelo superplasticizer C-3 zithutha

Kukhona olunye uhlobo ezivamile plasticizer, okuyinto kuveza ngokuvumelana TU 2481-111-07511608-2012. Lapho yalolu ketshezi ine uhlobo microgranules ezithinta tinge ukukhanya yellow noma ensundu. Isici esiyinhloko sokuqanjwa obonakaliswe ngobuningi kwabantu, okuyinto ilingana kumkhawulo 0,50-0,80 g / cm ^3. ingxenyenamba IMisa yamanzi plasticizer ukuhlukahluka okunjalo kumele singeqi 10%. Kodwa-hydrogen ion Inkomba umsebenzi amabanga kusuka 7 kuya 10. Yini engashiwo ukuze ikhambi aqueous, lo ingxenyenamba mass impahla okuyinto ilingana 2.5%.

Okufakiwe futhi isitoreji okwalandela

a superplasticizer okunjalo kwi polypropylene izikhwama, isisindo okuyinto, ngemva kokuba ukugcwaliswa 20 kg. Gcina izimonyo futhi kudingeka emafektri ehlanganiswa anoma yiluphi uhlobo. Kodwa umkhiqizi uncoma ukusebenzisa plasticizer unyaka ongu-1.

Izindleko izinhlobo ezahlukene plasticizer C-3

Superplasticizer, intengo zazo iyahlukahluka kuye ngokuthi inguqulo, kubalulekile ukuba ukuthenga kuphela ngemva kokubala lemali edingekile of material. Lokhu kuyokwenza ugcine kakhulu ukuqaliswa wokwakha imisebenzi. Ngakho, uma kukhona isidingo ukusebenzisa uketshezi plasticizing izithasiselo ezihlukahlukene emisiwe, kubalulekile kuyodingeka bakhokhe ruble 28 kilogram per. Kodwa plasticizer e powder kungase kubize kakhulu. wentengo ngayinye amakhilogramu kuze ruble 120.

Noma yini wakhetha ukwakhiwa superplasticizer - liquid noma owomile, kuzomele uqale ufunde kabanzi mayelana nezici yokusetshenziswa kwawo. Phela, ukusetshenziswa engalungile kungaholela izindleko ezengeziwe, futhi umphumela kulindeleke ngeke bakwazi ukuthola.
