Uhlobo: Zoncore
Uhlobo: I-Polycarboxylate Slump-Retaining Agent
1. Uhlolojikelele Lomkhiqizo Nokwakheka Kwezinto
I-ZK-7E iyisithako samakhemikhali esisebenza kahle kakhulu esiklanyelwe ngokukhethekile ukusetshenziswa kukakhonkolo.Ukwakheka Kwamakhemikhali: Yakhiwa ngobuchwepheshe be-free-radical copolymerization. Izinto zokuqala ezisetshenziswayo zihlanganisa i-C6 polyether macromonomers kanye ne-hydroxypropyl esters. Yakhelwe nge-“isikhathi-ubuchwepheshe bokukhishwa okulawulwayo,” obuvumela ukukhishwa okuqhubekayo kwezingxenye ezisebenzayo ngokusebenzisa i-ester hydrolysis, kuqinisekisa ukuthi inani le-slump kakhonkolo lihlala lingashintshi cishe amahora angu-3. I-ZK-7E inikeza isixazululo esibalulekile se- ukuthuthwa kukakhonkolo amabanga amade kanye namaphrojekthi adinga izikhathi zokubekwa ezinwetshiwe, okuqinisekisa ukuthi ukhonkolo ufika endaweni ukuthi ulungele ukuthelwa ngaphandle kokulahlekelwa amandla noma ukuzinza kobukhulu.
Isimo Somzimba: Uketshezi olungenambala, olubonakalayo.
Ubuchwepheshe Obubalulekile: Busebenzisa "ubuchwepheshe bokukhishwa okulawulwa isikhathi," obuvumela ukukhishwa okuqhubekayo kwezingxenye ezisebenzayo ngokusebenzisa i-ester hydrolysis.
2. Izici Eziyinhloko Nemisebenzi
Umsebenzi oyinhloko wale agent ukugcina ukusebenza (slump) kakhonkolo isikhathi eside ngaphandle kwemiphumela emibi.
Ukugcinwa Kwe-Slump Isikhathi Eside Kakhulu: Kuklanyelwe ukugcina inani le-slump kakhonkolo lingashintshi cishe amahora angu-3 (imizuzu engu-180).
Ukusebenza Okuzinzile: Ngokuvamile ifinyelela umthamo wayo wokugcina i-slump emizuzwini engaba ngu-90. Ngemva kokukhishwa komphumela wokugcina, i-slump kakhonkolo ihlala izinzile ngaphandle kwezinguquko ezingazelelwe.
Ukunciphisa Ukufinyela: Inciphisa kakhulu ukufinyela kukakhonkolo, ithuthukisa ukuzinza kwevolumu nokuqina kwesakhiwo sokugcina.
Ukuhambisana: Iklanyelwe ngokukhethekile ukuthi isetshenziswe kanyekanye nezinciphisi zamanzi ezisebenza kahle kakhulu ezisekelwe ku-polycarboxylate.
3. Imininingwane Yobuchwepheshe
Ithebula elilandelayo lifingqa izidingo ezijwayelekile nemiphumela yokuhlolwa kukakhonkolo oqukethe i-ZK-7E:
4. Izimo Zokusebenzisa
Lo mkhiqizo ulungele amaphrojekthi kakhonkolo adinga ukugcinwa kwe-slump isikhathi eside kakhulu kanye nokuthuthwa amabanga amade, okuhlanganisa:
Amaphrojekthi Okhonkolo Wokuhweba
Izitimela Ezinesivinini Esikhulu
Imigwaqo Eshaywayo
Iziteshi Zamandla Enuzi
Izikhungo Zokulawula Amanzi
5. Ukupakisha Nokugcina
Izinketho Zokupakisha:
Imigqomo yepulasitiki
Amabhasikidi e-IBC: 1000L.
Amaloli Amanzi: Okuthutha ngobuningi.
Izimo Zokugcina:
Isikhathi Sokuphila: Max. izinyanga eziyisi-6
Izexwayiso: Vala kahle, gwema ukukhanya kwelanga okuqondile, futhi uvikele ekubandeni.
Isexwayiso Sokugqwala: Inomphumela omncane wokugqwala ezitsheni zensimbi. Ukugcinwa isikhathi eside ezitsheni zensimbi kuzobangela ukuthi okuqukethwe kuphenduke umbala onsundu obomvu ngokukhanyayo. Ayinabo ubuthi, inephunga elincane elimuncu, futhi ayivuthi.
6. Izinyathelo Zokucophelela Ezibalulekile
Ungaxubanisi ne-naphthalene sulfonate water reducers, i-melamine-based water reducers, noma i-aliphatic water reducers.
Umthamo: Umthamo onconyiwe we-ZK-7E ngu-0.1% –0.3% ngesisindo se-binder ephelele. Ukwengezwa ngokweqile kungaholela ekwandeni kwe-slump kakhonkolo futhi ngisho nokubangela ukwehlukana kakhonkolo.
Umthelela Othuthukisiwe: Uma kusetshenziswa kuhlangene nama-polycarboxylate high-performance water reducers kanye ne-Type I polycarboxylate slump-retaining agents, umphumela uba sobala nakakhulu.
7. MOQ: amathani ama-5
Izinzuzo zomkhiqizo:
1. Ukugcinwa Kwe-Slump Okude Kakhulu (Ukusebenza Okunwetshiwe)
Ukukhishwa Okulawulwa Isikhathi: Kusebenzisa ubuchwepheshe obungokomfaniswano "bokukhishwa okulawulwa isikhathi" obusekelwe ekuhlukanisweni kwe-ester hydrolysis. Lokhu kuvumela i-agent ukuthi ikhishwe izingxenye zayo ezisebenzayo kancane kancane ngokuhamba kwesikhathi.
Ukuzinza Kwamahora Amathathu: Yakhelwe ukugcina inani lokwehla kukakhonkolo lingashintshi isikhathi esingafika emahoreni amathathu (imizuzu eyikhulu nengamashumi ayisishiyagalombili).
Akukho Ukuwa Ngokuzumayo: Umphumela wokugcina ukwehla kwe-slump uvame ukufinyelela umvuthwandaba emizuzwini engaba ngu-90. Ngemva kwalesi sikhathi, i-slump kakhonkolo ihlala izinzile ngaphandle kwezinguquko ezingazelelwe noma ukulahlekelwa okungazelelwe kokugeleza, okuvumela isikhathi eside nesethembekile sokusetha.
2. Ukuhambisana Okuhle Nokusebenzisana
Umsebenzi Ohambisanayo: Yakhelwe ngokukhethekile ukuthi isetshenziswe kanye nezinciphisi zamanzi ezisebenza kahle kakhulu ezisekelwe ku-polycarboxylate.
Umthelela Othuthukisiwe: Uma isetshenziswa kanye nezinhlobo zokuqala ze-polycarboxylate ezokugcina ukwehla kanye nezinhlobo zesibili noma zesithathu ze-polycarboxylate ezokugcina ukwehla, umphumela wokusebenzisana uba sobala nakakhulu, okuvumela ukulawula okunembile kokugeleza kukakhonkolo.
3. Ukuqina Okuthuthukisiwe Nokuzinza Kobukhulu
Ukuncipha Okuncishisiwe: Kunciphisa kakhulu ukuncipha kukakhonkolo. Imibhalo ikhombisa izinga lokuncipha kwezinsuku ezingama-28 lingu-109% kuphela (uma kuqhathaniswa nemfuneko ejwayelekile ye-≤120%), ukuthuthukisa ukuzinza kwevolumu yesakhiwo nokunciphisa ubungozi bokuqhekeka.
Ukugcinwa kwamandla: Ngenkathi kugcina i-slump, akudeli amandla. Isilinganiso samandla okucindezela sezinsuku ezingama-28 sifinyelela ku-108%, kuqinisekisa ukuthi ubuqotho besakhiwo kakhonkolo buhlala buphezulu.
4. Isikhathi Sokumisa Esizinzile
Ukusetha Okulawulwayo: Inikeza umphumela ophakathi nendawo wokubambezela. Umehluko wesikhathi sokuqala sokumisa ngu-+20 imizuzu, oqinisekisa ukuthi ukhonkolo awumisi ngokushesha kakhulu phakathi nezikhathi ezinde zokuthutha kodwa futhi awulibambezeli kakhulu ishejuli yonke yokwakha.
Lokhu kuyinkomba kuphela kodwa akusho ukuthi kuphelele futhi akukho sibopho. Sicela uqhubekele phambili ukuze uhlole ukusebenza.
