1.Ukusebenza kusimende:
Ukwakheka kukasimende nezinto zikasimende kuyinkimbinkimbi futhi kuyashintsha.Ngokombono we-adsorption-dispersion mechanism, akunakwenzeka ukuthola i-ejenti yokunciphisa amanzi elungele yonke into.Nakubai-polycarboxylate i-ejenti yokunciphisa amanzi inokuguquguquka okubanzi kunochungechunge lwe-naphthalene, kusengenzeka ibe nokuvumelana nezimo okungekuhle kwamanye usimende.Lokhu kuvumelana nezimo kubonakala kakhulu kulokhu: ukuncipha kwezinga lokuncishiswa kwamanzi kanye nokwenyuka kokulahleka kokuwohloka.Ngisho noma kuwusimende ofanayo, umphumela we-ejenti yokunciphisa amanzi uzohluka uma ibhola ligaywa ekucoleni okuhlukile.
Ukwenzeka:Isiteshi sokuxuba sisebenzisa usimende othile we-P-042.5R endaweni ukuze sinikeze ukhonkolo ongu-C50 endaweni yokwakha.Isebenzisa i-api-olycarboxylatesi-uperplasticizeri-ejenti yokunciphisa amanzi.Lapho wenza isilinganiso sokuxuba ukhonkolo, kutholakala ukuthi inani le-ejenti yokunciphisa amanzi elisetshenziswe kusimende Lingaphezu kancane kwamanye amasimende, kodwa ngesikhathi sokuxuba kwangempela, ukuwohloka kwengxube yekhonkrithi yefekthri kwakulinganiswa ngokubonakalayo ukuze kube ngu-21Omm.Lapho ngiya lapho kwakhiwa khona ukuyothulula iloli elimpompa ukhonkolo, ngathola ukuthi iloli lalingakwazi ukukhipha ukhonkolo.Ngazisa ifekthri ukuthi ithumele umgqomo.Ngemva kokuba i-ejenti yokunciphisa amanzi yengezwe futhi ixutshwe, ukuwohloka okubonakalayo kwaba ngu-160mm, okwakuhlangabezana nezidingo zokupompa.Nokho, phakathi nenqubo yokuthulula, kwabonakala sengathi ngeke kuthululwe.Iloli likakhonkolo labuyiselwa ngokushesha efektri, futhi kwanezelwa inani elikhulu lamanzi nenani elincane lokunciphisa izinto.I-ejenti ye-liquid ayizange ikhishwe futhi icishe yaqina elolini le-mixer.
Ukuhlaziywa kwesizathu:Asizange siphikelele ekwenzeni izivivinyo zokuvumelana nezimo nezixube kuqeqebana ngalinye likasimende ngaphambi kokuvula.
Ukuvimbela:Yenza ukuhlolwa kokuhlanganisa ngesilinganiso sokuxuba ukwakhiwa kweqoqo ngalinye likasimende ngaphambi kokuvula.Khetha izixube ezifanele."I-Gangue" njengengxube kasimende ayinakho ukuguquguquka okungalungile ku-pi-olycarboxylate si-uperplasticizerama-ejenti okunciphisa amanzi, ngakho gwema ukuwasebenzisa.
2.Ukuzwela ukusetshenziswa kwamanzi
Ngenxa yokusetshenziswa kwei-polycarboxylate i-ejenti yokunciphisa amanzi, ukusetshenziswa kwamanzi kokhonkolo kuyancipha kakhulu.Ukusetshenziswa kwamanzi kokhonkolo owodwa kakhonkolo ngokuvamile ku-130-165kg;isilinganiso samanzi nosimende singu-0.3-0.4, noma singaphansi kuka-0.3.Endabeni yokusetshenziswa kwamanzi okuphansi, ukushintshashintsha kokwengezwa kwamanzi kungase kubangele izinguquko ezinkulu ekuwohlokeni, kubangele ingxube kakhonkolo ukuthi inyuke ngokuzumayo ekuweni nokopha.
Ukwenzeka:Isiteshi sokuxuba sisebenzisa usimende i-P-032.5R evela efekthri ethile kasimende ukuze silungise ukhonkolo we-C30.Inkontileka idinga ukuthi ukuwohloka kwendawo yokwakha kube ngu-150mm:t30mm.Lapho ukhonkolo usuka efektri, ukuwohloka okulinganiselwe kungu-180mm.Ngemva kokuhanjiswa endaweni yokwakha, ukhonkolo ukalwa endaweni yokwakha.Ukuwa bekuyi-21Omm, kwabuyiswa amaloli amabili kakhonkolo elandelana.Lapho kubuyiswa efemini, kwaqinisekiswa ukuthi ukuwohloka kwakusengu-21Omm, futhi kwakuphuma ukopha nokuphuma kwegazi.
Isizathu:Lo simende unokuvumelana kahle nezimo kule ejenti yokunciphisa amanzi, futhi inani le-ejenti yokunciphisa amanzi likhulu kancane.Isikhathi sokuxuba asanele, futhi ukuwohloka kwekhonkrithi lapho ushiya umshini akuyona i-slump yangempela ngenxa yesikhathi esifushane sokuxuba.
Ukuvimbela:Ngosimende ozwela umthamo we-pi-olycarboxylatesi-uperplasticizerama-admixtures okunciphisa amanzi, umthamo we-admixtures kufanele ube ofanele futhi ukunemba kokulinganisa kufanele kube phezulu.Yandisa kahle isikhathi sokuxuba.Ngisho ne-twin-shaft ephoqelelwe mixer, isikhathi sokuxuba akufanele sibe ngaphansi kwamasekhondi angu-40, okungcono ngaphezu kwamasekhondi angu-60.
