1.Ukuzungeza usimende:
Ukwakheka kukasimende kanye nezinto zokwakha cementile kuyinkimbinkimbi futhi kuyashintsha. Ngokombono wendlela yokuhlakazeka kwe-adsorption, akunakwenzeka ukuthola i-ejenti enciphisa amanzi efanelekile yonke into. Nokhopolycarboxylate Umenzeli oncishisiwe amanzi unobuhlakani obukhulu kunochungechunge lweNaphthalene, kusenokuvumelana okumpofu ngezimo ezithile. Lokhu kuzivumelanisa nezimo kuboniswa kakhulu ku: Kuncishiswe isilinganiso sokuncipha kwamanzi kanye nokulahleka kokuncipha. Noma ngabe kufana nesimende, umphumela we-ejenti yokunciphisa amanzi uzohluka lapho ibhola liyabumba ubunzima obuhlukile.
IPhenomenoni:Isiteshi sokuxuba sisebenzisa usimende othile we-P-042.5R endaweni yendawo ukuhlinzeka ngokhonkolo we-C50 endaweni yokwakha. Isebenzisa i-API-OlycarboxylatesI-UperPlastizeri-ejenti yokunciphisa amanzi. Lapho wenza isilinganiso sokhonkolo sixube, kutholakala ukuthi inani le-ejenti elincishisiwe lamanzi elisetshenziswa ku-usimende lingaphezu kwamanye amamitha, kepha lapho kuxubana kwangempela, ukuncibilika kwento ekhonkolo yefektri kulinganiswe ngo-2. Lapho ngiye esakhiweni sokwakha ngithulule iloli ekhonkolo yepompo, ngathola ukuthi iloli alikwazanga ukusula ukhonkolo. Ngazise ifektri ukuthumela umgqomo. Ngemuva kokuthi umenzi oncishisiwe wamanzi wengezwe futhi ahlanganiswe, ukuncibilika okubukwayo kwakungu-160mm, owayehlangabezana nezidingo zokupompa. Kodwa-ke, ngesikhathi senqubo yokulayisha, kwavela ukuthi ngeke ilayishwe. Iloli likakhonkolo labuyiselwa ngokushesha efektri, kwafakwa inani elikhulu lamanzi kanye nenani elincane le-ejenti yokunciphisa. I-ejenti yoketshezi yayidedelwa futhi yacishe yaqina elolini le-mixer.
Ukuhlaziywa kwesizathu:Asizange siphikelele eqhuba izivivinyo eziguqukayo nge-admixtures kwi-batch ngayinye kasimende ngaphambi kokuvula.
Ukuvimbela:Yenza isivivinyo esijabulisayo ngesilinganiso sokuxuba sokwakha nge-batch ngayinye yesimende ngaphambi kokuvula. Khetha ama-admixtures afanele. "IGangue" njengoba ukuhlangana kosekhumenti kunokuzivumelanisa nezimo ezingezinhle ku-PI-Olycarboxylate sI-UperPlastizerAmanzi anciphisa ama-ejenti, ngakho-ke gwema ukuyisebenzisa.
2.Sensitivity kokusetshenziswa kwamanzi
Ngenxa yokusetshenziswa kwepolycarboxylate I-ejenti yokunciphisa amanzi, ukusetshenziswa kwamanzi kokhonkolo kuncishiswe kakhulu. Ukusetshenziswa kwamanzi ukhonkolo owodwa kakhulu kungu-130-165kg; Isilinganiso samanzi-usimende singu-0.3-0.4, noma ngaphansi kuka-0.3. Endabeni yokusetshenziswa kwamanzi okuphansi, ukuguquguquka kokungezwa kwamanzi kungadala ushintsho olukhulu ngokuncibilika, okwenza ukuthi inhlanganisela ekhonkolo ikhule ngokuzumayo ekunciphiseni nopha.
IPhenomenoni:Isiteshi sokuxuba sisebenzisa usimende we-P-032.5r kusuka efektri ethile yesimende ukulungiselela ukhonkolo we-C30. Inkontileka idinga ukuthi ukuncibilika endaweni yokwakha kungu-150mm: T30mm. Lapho ukhonkolo eshiya ifektri, i-slump elinganisiwe ingu-180mm. Ngemuva kokuthunyelwa esakhiweni, ukhonkolo ulinganiswa endaweni yokwakha. Ukushiswa kwaba ngu-2 ngonyaka ka-Aloyman, kwabuyiselwa amaloli amabili kakhonkolo ngokulandelana. Lapho ibuyela efektri, yaqinisekiswa ukuthi i-slump ibisengu-2 ngonyaka, futhi kwaphela ukopha nokuhlehlisa.
Isizathu:Lo msele unokuzivumelanisa nezimo okuhle kulokhu kuncishiswa kwamanzi, kanye nenani le-ejenti elanciphisa lamanzi likhudlwana kancane. Isikhathi sokuxuba asanele, kanye nokwehla kokhonkolo lapho ushiya umshini akuyona indawo eyiqiniso ngenxa yesikhathi esifushane sokuxuba.
Ukuvimbela:Ngokosimende ozwela umthamo we-pI-OlycarboxylatesI-UperPlastizerUkuncipha kwamanzi okunciphisa amanzi, umthamo we-admixtures kumele ulunge futhi ukunemba kokulinganisa kumele kube phezulu. Ukunweba kahle isikhathi sokuxuba. Noma nge-Twin-Shaft Forced Mixer, isikhathi sokuxuba akufanele kube ngaphansi kwemizuzwana engama-40, mhlawumbe imizuzwana engaphezu kwama-60.
