Kufurira kwedhaka rejecha papolycarboxylate superplasticizerkazhinji inouraya, izvo zviri pachena kupfuura naphthalene series uye aliphatic superplasticizers. Kana madhaka akawedzera, kushanda kwekongiri kunovandudzwa nekuwedzera kuwanda kwepolycarboxylate superplasticizer, dzimwe nguva nehafu yenhamburiko, uye dzimwe nguva kubuda ropa kunotanga kusati kwasvikirwa. Kana madhaka emusanganiswa akakwana anopfuura 5%, mwero wekudzikisa mvura wekongiri yakasanganiswapolycarboxylate superplasticizervachaderera, uye kunyange ivo
fluidity icharasika zvachose, uye slump retention performance ichave yakashata. Kune zviri mukati mehupfu hwematombo, zvinodiwawo kuita pa-saiti bvunzo kakawanda kuti udzore zvine musoro zviri mukati mehupfu hwebwe, kuitira kuti senitivity igone kudzorwa zvakanaka, kuyerera kwekongiri kunogona kuvimbiswa, uye kuita kwe kongiri inogona kugadzirwa.
Kune dambudziko razvino remadhaka emukati, pane akati wandei akajairwa mhinduro:
(1) Wedzera muyero kana kuwedzera chikamu cheanononoka-kusunungurwa-anochengetedza mumiriri, asi kudzora huwandu hwekudzivirira matambudziko ekutsvuka, kubuda ropa, kupatsanurwa, kubata pasi uye kongiri kunonoka nguva kuve yakarebesa;
(2) Gadzirisa jecha rejecha kana kuwedzera huwandu hwemhepo-inopinza. Pamusoro pekusimbisa kushanda kwakanaka uye simba, kuderedza chiyero chejecha kana kuwedzera huwandu hwemhepo-inopinza kuti uwane chinangwa chekuwedzera mvura yemahara uye slurry huwandu hwekongiri system. kugadzirisa zvinhu zvekrete;
(3) Wedzera kana kushandura zvikamu kuti ugadzirise dambudziko. Ongororo dzakaratidza kuti kuwedzera huwandu hwakakodzera hwesodium metabisulfite, sodium thiosulfate, sodium hexametaphosphate, uye sodium sulfate kune inoderedza mvura inogona kuderedza pesvedzero yedhaka remukati kongiri kusvika pamwero wakati.
Ehe, nzira dziri pamusoro apa hadzigone kugadzirisa matambudziko ese emukati medhaka, uye mhedzisiro yedhaka pane kusimba kwekongiri inoda kumwe kutsvagisa, saka mhinduro yakakosha ndeyekudzikisa madhaka ezvinyorwa.
