Ndị na-ebelata mmiri na-abụkarị anionic surfactants, na ugbu a na-ejikarị n'ahịa gụnyere polycarboxylic acid dabeere na mmiri na-ebelata ihe ndị na-ebelata mmiri, naphthalene dabeere na mmiri na-ebelata ihe, wdg. , meziwanye ike ihe, ma belata ihe omume nke mgbape. Ha na-ekere òkè dị mkpa n'ịchịkwa ihe arụrụ arụ. Otú ọ dị, ngwakọta kọnkịtị jikọtara ya na ndị na-ebelata mmiri nwere ike izute nsogbu ndị dị ka ịrapagidesi ike na tank na ntọala ụgha. Iji zere ọnọdụ nke nsogbu dị iche iche, Freeman ga-enyocha ihe kpatara na ngwọta nke nsogbu n'otu n'otu.
一. Nwere ike ịrapara phenomen:
Phenomenon: Akụkụ nke ngwa ngwa ciment na-arapara n'ahụ mgbidi nke cylinder mixer, na-eme ka mwụpụ ntụ na-adịghị mma na nke na-erughị ala nke kọnkịrị, na-ebute kọmpụta na-egbuke egbuke.
Nyocha ihe kpatara ya:
Concrete sticking na-emekarị mgbe agbakwunyere ndị na-azụ azụ na ihe ndị na-ebelata mmiri, ma ọ bụ n'ime igwe na-agwakọta drum nwere oke axial nke yiri ya.
Usoro mmezi:
(1) Lezienụ anya n'oge kwesịrị ekwesị na nhicha na iwepụ ihe ndị fọdụrụ;
(2) Nke mbu, gbakwunye aggregates na mmiri ka ị gwakọta, wee tinye ciment, mmiri fọdụrụnụ, na ihe na-ebelata mmiri ka ị gwakọta;
(3) Jiri nnukwu oghere dayameta ma ọ bụ igwekota mmanye.
二. Pseudo coagulation phenomen
Phenomenon: Ihe ahụ mgbe ọ hapụsịrị igwe ngwa ngwa na-efunahụ mmiri ya na ọbụna enweghị ike ịwụsa ya.
Nyocha ihe kpatara ya:
(1) Enweghị ọdịnaya nke calcium sulfate na gypsum na ciment na-eduga ngwa ngwa hydration nke calcium aluminate;
(2) Onye na-eme ka mmiri na-ebelata mmiri enweghị ike ime mgbanwe maka ụdị ciment a;
(3) Mgbe ọdịnaya nke triethanolamine karịrị 0.05-0.1%, ntọala mbụ dị ngwa ngwa ma ọ bụghị ntọala ikpeazụ.
Usoro mmezi:
(1) Gbanwee ụdị ciment;
(2) Ọ bụrụ na ọ dị mkpa, gbanwee admixtures ma mee ihe mgbagwoju anya;
(3) Tinye Na2SO4 akụrụngwa na admixture.
(4) Belata ikpokọta okpomọkụ
