Idethi yokuthunyelwe:19, Feb,2024
Izici zendlela yokwakha:
(1) Lapho uklama ingxenye yengxube kakhonkolo, ukusetshenziswa okuyinhlanganisela kwe-ejenti yokunciphisa amanzi esebenza kahle kakhulu kanye ne-ejenti yokungenisa umoya kuxazulula izidingo zokuqina zezakhiwo zikakhonkolo ezindaweni ezibandayo kakhulu;
(2) Ngokuhlanganisa izingxenye zokulondoloza ukwehla kwezinga eliphezulu ekusebenzeni okuphezulu kokunciphisa amanzi, umthelela wamazinga okushisa aphezulu ehlobo ekusebenzeni kokukhonkolo uyaxazululwa;
(3) Ngokuhlaziywa kokuhlola, ithonya lodaka okuqukethwe kukhonkolo ekusebenzeni namandla okucindezela kakhonkolo;
(4) Ngokuhlanganisa isihlabathi esimahhadlahhadla nesihlabathi esicolekile esilinganisweni esithile, isenzakalo sokuthi uhlobo olulodwa lwesihlabathi sikakhonkolo alukwazi ukuhlangabezana nokusebenza kukakhonkolo luyaxazululeka;
(5) Izici ezithinta ukusebenza kwekhonkrithi zichazwe, futhi umthelela wezici ezimbi ekusebenzeni kokusebenza kokhonkolo ugwenywa ngesikhathi senqubo yokwakha ukhonkolo.
Umgomo wokusebenza we-ejenti yokunciphisa amanzi esebenza kahle kakhulu:
(1) Ukuhlakazwa: I-ejenti yokunciphisa amanzi i-adsorbed ngendlela eqondile ebusweni bezinhlayiya zikasimende, okwenza zithwale inkokhiso efanayo ukuze zenze i-electrostatic repulsion, ekhuthaza izinhlayiya zikasimende ukuba zihlakazeke zodwa, zicekela phansi isakhiwo sokugeleza esakhiwe usimende oludaka, futhi ukhulula ingxenye yamanzi asongwe. Khulisa ngempumelelo i-fluidity yengxube kakhonkolo.
(2) Umphumela we-Lubricant: I-ejenti yokunciphisa amanzi ineqembu elinamandla kakhulu le-hydrophilic, elenza ifilimu yamanzi ebusweni bezinhlayiya ze-samente, ukunciphisa ukumelana nokuslayida phakathi kwezinhlayiya ze-cement, ngaleyo ndlela ithuthukise ngokwengeziwe uketshezi lwekhonkrithi.
(3) Isithiyo se-steric: I-ejenti yokunciphisa amanzi inamaketanga aseceleni e-hydrophilic polyether, akha ungqimba lwe-hydrophilic lwe-adsorption enezinhlangothi ezintathu ebusweni bezinhlayiya zikasimende, okubangela ukuthikamezeka okuqinile phakathi kwezinhlayiya zikasimende, ngaleyo ndlela kuqinisekiswe ukuthi ukhonkolo unezakhiwo ezinhle. ukuwohloka.
(4) Umphumela wokukhishwa kancane kwamagatsha axhunywe nge-copolymerized: Ngesikhathi sokukhiqiza nokulungiswa kwama-ejenti amasha okunciphisa amanzi, amaketanga anamagatsha anemisebenzi ethile ayengezwa. Lolu chungechunge lwe-branched alugcini nje ngokuba nomphumela we-steric hindrance, kodwa futhi lungasetshenziswa ngesikhathi se-hydration ephezulu ye-samente. Ama-Polycarboxylic acid anemiphumela yokuhlakaza akhululwa endaweni ene-alkali, ethuthukisa umphumela wokuhlakazeka kwezinhlayiya zikasimende futhi ilawule ngempumelelo ukulahleka kokuwohloka kukakhonkolo phakathi nenkathi ethile yesikhathi.
Isikhathi sokuthumela: Feb-19-2024
