Isinciphisi samanzi se-Polycarboxylate(I-PCE)uhlobo olusha lomshini wokunciphisa amanzi osebenza kahle kakhulu futhi onobungani nemvelo, olusetshenziswe kabanzi emikhiqizweni eyahlukahlukene yekhonkrithi, ikakhulukazi ekukhiqizweni kwemikhiqizo yekhonkrithi esetshenzisiwe. Ngokuthuthuka kwezimboni zokwakha, izingxenye zekhonkrithi zithuthuke ngokushesha emikhakheni yezindlu, ezokuthutha, ukuphathwa komasipala, njll., futhi i-PCE powder isibe ngenye yezingxube ezibalulekile zokuthuthukisa ikhwalithi kanye nokusebenza kahle kokwakhiwa kwezingxenye zekhonkrithi ngenxa yokusebenza kwayo okuhle kakhulu kanye nokuzivumelanisa nezimo.
1. Isingeniso ku-PCE powder
Impuphu ye-PCE iwuhlobo oluqinile lwe-polycarboxylate water reducer enokusabalalisa okuhle kakhulu, ukugcinwa kokugoba kanye nokuhambisana. Uma kuqhathaniswa ne-PCE ewuketshezi, impuphu ye-PCE kulula ukuyithutha nokuyigcina, ifanele ukusetshenziswa ku-mortar exutshwe okomile, izinto zokwakha zempuphu eyomile kanye nezimo ezingenamanzi, ifaneleka kakhulu ezidingweni zokukhiqizwa kwekhonkrithi eqanjwe kusengaphambili okusekelwe efektri kanye nobuningi.
2. Izici kanye nezinselele zekhonkrithi eqanjwe kusengaphambili
Imikhiqizo yekhonkrithi ebekwe kusengaphambili ifaka phakathi imishayo ebekwe kusengaphambili, amaphaneli odonga abekwe kusengaphambili, izitebhisi ezibekwe kusengaphambili, ama-sleepers, izingxenye zamapayipi, njll. Lezi zingxenye zinezici ezilandelayo:
Izidingo zamandla aphezulu: Ukhonkolo uyadingeka ukuze ube namandla aphezulu okuqala kanye namandla okugcina ukuze kusheshiswe ukudilizwa kanye nenqubekela phambili yokuthutha.
Ukugeleza okuhle: Ikakhulukazi uma ukhonkolo ozimele (i-SCC) osetshenziselwa ukubumba isikhunta, ukugeleza okuhle kumele kugcinwe ukuqinisekisa ubuningi kanye nekhwalithi yokubukeka.
Umjikelezo wokwakha osheshayo: Ukhonkolo uyadingeka ukuze kuthuthukiswe amandla asheshayo kusenesikhathi, okusiza ekuthuthukiseni ukusebenza kahle kokukhiqiza.
Ukunemba okuphezulu: Isidingo sokulahlekelwa okuncane kwekhonkrithi sibonakala kakhulu.
Ngakho-ke, izidingo eziphakeme zibekwa phambili ezinciphisweni zamanzi, okungukuthi, izinga eliphezulu lokunciphisa amanzi, ukugcinwa okuhle kokuwa kanye nesikhathi sokusetha esilawulekayo kuyadingeka.
3. Izinzuzo zempuphu ye-PCE kukhonkrithi elungisiwe
3.1. Ukusebenza kahle kokunciphisa amanzi
Impuphu ye-PCE inokusebenza okuhle kakhulu kokusabalala. Ingasonga futhi isakaze izinhlayiya zesimende ngesakhiwo esikhulu seketanga kanye neseketanga eliseceleni esakhiweni sama-molecule, futhi ingafinyelela izinga lokunciphisa amanzi elingaphezu kuka-20% ngesilinganiso esiphansi. Lokhu kusiza ukuthuthukisa ukuqina nokuqina kwekhonkrithi futhi kuhlangatshezwane nezidingo zokusebenza okuphezulu kwezingxenye ezilungisiwe.
3.2. Ukusebenza okuhle kakhulu okulondoloza ukwehla
Ukukhiqizwa kwekhonkrithi elungisiwe ngokuvamile kudinga ukuxubaniswa kusengaphambili kanye nokuthuthwa ukuya endaweni yokuthululwa, okudinga ukuthi ikhonkrithi igcine uketshezi oluhle isikhathi esithile. Impuphu ye-PCE inokuqina okuqinile kokusabalala, okubambezela ukulahlekelwa ukuwohloka ngenkathi kugwema ukulahlekelwa amanzi ngokushesha, okuqinisekisa ukusebenza kwekhonkrithi kuyo yonke inqubo yokwakha.
3.3. Thuthukisa amandla okuqala
Impuphu ye-PCE yenza ngcono isilinganiso sangaphakathi sokubopha amanzi kanye nobuningi bekhonkrithi, ngenkathi ikhuthaza ukusabela okusheshayo kokumanzisa kwesimende, okusiza ukuthuthukisa amandla okuqala. Lokhu kusebenza kufaneleka kakhulu enkambisweni yokukhiqizwa kwesikhunta esisheshayo kanye nokukhuculula okusheshayo kwezingxenye ezilungisiwe, kunciphisa isikhathi sokukhuculula kanye nokuthuthukisa ukusebenza kahle kokushintsha kwesikhunta.
3.4. Ukuhambisana kahle nezinto ezahlukahlukene ezifaka usimende
Impuphu ye-PCE iyakwazi ukuzivumelanisa kahle nezinhlobo ezahlukene zesimende kanye nezingxube (njengomlotha wezimpukane, i-slag, i-silica fume, njll.), futhi ifaneleka emiklamo ehlukahlukene yokuxuba. Ingalungiswa kalula ngokwezidingo zephrojekthi ukuze kuthuthukiswe ukusebenza okuphelele kwekhonkrithi.
3.5. Ukuvikelwa kwemvelo kanye nezinzuzo eziphansi zekhabhoni
Impuphu ye-PCE ngokwayo iyinto yokwakha enobungani nemvelo futhi ayinazo izithako eziyingozi. Umphumela wayo omuhle wokunciphisa amanzi unganciphisa ukusetshenziswa kwamanzi kanye nesimende, ngaleyo ndlela unciphise umthelela wekhabhoni wekhonkrithi, okuhambisana nomkhuba wezakhiwo eziluhlaza kanye nentuthuko eqhubekayo.
4. Amacala okusetshenziswa okukhethekile kwempuphu ye-PCE ezingxenyeni ezilungisiwe
Ikhonkrithi yezingxenye: Izingxenye ezisetshenziswa emihubheni yokuvikela zidinga amandla aphezulu, ukuncishiswa okuphansi, kanye namandla okuqala ekhonkrithi. Ukusetshenziswa kwempuphu ye-PCE kungaqinisekisa ikhwalithi, ukuqina kanye nokusebenza kahle kokunciphisa izingxenye.
Ukukhiqizwa kwe-sleeper: I-sleeper idinga ukumelana nemithwalo emikhulu enamandla, okudinga ukuthi ukhonkolo ube nobuncane obuhle nokuqina. Izinga eliphezulu lokunciphisa amanzi le-PCE powder lisiza ekuthuthukiseni amandla nokuqina.
Amaphaneli odonga akhiwe kusengaphambili: Amaphaneli odonga akhiwe kusengaphambili asetshenziswa ezakhiweni zokuhlala ezilungisiwe adinga ikhwalithi enhle yendawo kanye nokunemba okulinganayo. Ukusetshenziswa kwempuphu ye-PCE kungathuthukisa kakhulu umphumela wokubumba kwendawo yekhonkrithi.
Izingxenye ze-PC (ukhonkolo osuvele ulungisiwe): Ukusetshenziswa kwempuphu ye-PCE ezingxenyeni ezifana nemishayo nezitebhisi ezilungisiwe kungaqinisekisa ukuhambisana nokuzinza kokukhiqizwa ngobuningi futhi kuthuthukise ukusebenza kahle kokwakha.
5. Izinyathelo zokuqapha zokusetshenziswa
Ukulawulwa kwesilinganiso: Ngokuvamile kunconywa ukuthi isilinganiso sempuphu ye-PCE sibe ngu-0.1% ~ 0.3% wesisindo sezinto ezifakwe usimende. Isilinganiso esithile sidinga ukunqunywa ngokuya ngezinto zokusetshenziswa kanye nokuhlolwa okudingekayo.
Izimo zokugcina: Impushana idinga ukugcinwa endaweni eyomile ukuze kuvinjelwe ukumuncwa komswakama kanye nokuhlangana, okuzothinta ukusebenza kwayo.
Ukuhlolwa kokuhambisana nezinye izinto ezixubile: Ukuhlolwa kokuhambisana kuyadingeka uma kusetshenziswa ezinye izinto ezixubile (ezifana nezithibela kanye nezinto zokunweba) ukuze kugwenywe ukwehluleka kokusebenza.
Impuphu ye-PCEsekuyinto ebalulekile ekuhlanganisweni kwemikhiqizo yekhonkrithi eqanjwe kusengaphambili ngezinzuzo zayo zokusebenza kahle kakhulu ekunciphiseni amanzi, ukuvikela ukuwa, amandla okuqala kanye nokuvikelwa kwemvelo. Esikhathini esizayo, ngokuthuthukiswa kwezimboni zezakhiwo kanye nezinto zokwakha eziluhlaza, izidingo zokusebenza kwezingxenye eziqanjwe kusengaphambili zizoba ziphakeme, futhi i-PCE powder izoqhubeka nokudlala indima ebalulekile ekwenzeni ngcono ukusebenza kanye nokulawula okuhlakaniphile, inikeza ukwesekwa okuqinile kokuthuthukiswa kwekhwalithi yezingxenye eziqanjwe kusengaphambili kanye nokuguqulwa kokusebenza kahle kwesakhiwo.
