Mmiri reducer bụ ihe admixture nke nwere ike ibelata ego nke ịgwakọta mmiri mgbe ịnọgide na-enwe slump nke konkret. Ọtụtụ n'ime ha bụ anionic surfactants. Mgbe agbakwunyere ya na ngwakọta ihe, ọ na-enwe mmetụta na-agbasasị n'ahụ akụkụ ciment, nke nwere ike imeziwanye ọrụ ya, belata oriri mmiri nke unit, ma mee ka mmiri dị nro nke ngwakọta ihe; ma ọ bụ belata oriri ciment unit ma chekwaa ciment.
Dị ka ọdịdị ahụ si dị:
A na-ekewa ya na mmiri dabere na ntụ ntụ. Ọdịnaya siri ike nke mmiri dabere n'ozuzu 10%, 20%, 40% (nke a makwaara dị ka mmanya nne), 50%, na ọdịnaya siri ike nke ntụ ntụ bụ n'ozuzu 98%.
Dị ka ike ibelata mmiri na welie ike:
A na-ekewa ya na onye na-ebelata mmiri nkịtị (nke a makwaara dị ka plasticizer, nke na-ebelata mmiri nke na-erughị 8%, nke lignin sulfonates na-anọchi anya ya), onye na-ebelata mmiri na-arụ ọrụ nke ọma (nke a makwaara dị ka superplasticizer, na mbelata mmiri na-erughị 8%). karịa 14%, gụnyere usoro naphthalene, usoro melamine, usoro aminosulfonate, usoro aliphatic, wdg) na onye na-ebelata mmiri na-arụ ọrụ dị elu (ọnụego mbelata mmiri abụghị ihe na-erughị 25%, nke polycarboxylic acid na-anọchi anya onye na-ebelata mmiri mmiri), ma kewara ya n'ime. Ụdị ike mmalite, ụdị ọkọlọtọ na ụdị ntọala ngwa ngwa n'otu n'otu.
Dị ka ihe mejupụtara si dị:
Lignin sulfonates, polycyclic aromatic salts, resin sulfonates resin soluble, mmiri naphthalene nke na-ebelata mmiri na-arụ ọrụ nke ọma, ndị na-ebelata mmiri na-arụ ọrụ nke ọma nke aliphatic, ndị na-ebelata mmiri na-arụ ọrụ nke ọma, ndị na-ebelata mmiri polycarboxylate dị elu, wdg.
Dị ka ihe mejupụtara kemịkalụ siri dị:
Ndị na-ebelata mmiri Lignin sulfonate, ndị na-eme ka mmiri dị elu na-arụ ọrụ naphthalene, ndị na-eme ka mmiri dị elu na-eme ka melamine na-eme ka mmiri dị elu, ndị na-eme ka mmiri dị elu na-eme ka aminosulfonate na-eme ka mmiri dị elu, ndị na-eme ka mmiri dị elu nke fatty acid, ndị na-eme ka mmiri dị elu nke polycarboxylate. .
Ọrụ nke mbelata mmiri:
1.Without na-agbanwe agbanwe nke dị iche iche akụrụngwa (ma e wezụga ciment) na ike nke ihe, ọnụ ọgụgụ nke ciment nwere ike ibelata.
2.Without na-agbanwe agbanwe nke dị iche iche ngwaọrụ (ma e wezụga mmiri) na slump nke ihe, mbenata ego nke mmiri nwere ike ukwuu mma ike nke ihe.
3.Without na-agbanwe agbanwe nke dị iche iche ngwaọrụ, na rheology na plasticity nke ihe nwere ike dị ukwuu mma, nke mere na ihe owuwu nwere ike rụrụ site ike ndọda, pumping, na-enweghị vibration, wdg, na-amụba ewu ọsọ na-ebelata-ewu ike oriri. .
4.Ịgbakwunye ihe na-eme ka mmiri na-arụ ọrụ dị elu na-eme ka ọ bụrụ ihe nwere ike ime ka ndụ ihe dị elu karịa okpukpu abụọ, ya bụ, ịgbatị ndụ ọrụ nkịtị nke ụlọ ahụ karịa okpukpu abụọ.
5.Reduce the shrinkage rate of concrete solidification na-egbochi mgbawa na ihe components; meziwanye nguzogide ntu oyi, nke na-eme ka owuwu oyi.
Usoro ọrụ nke ndị na-ebelata mmiri:
· Mgbasa
· Mmanu mmanu
