Process for the fabrication of thinning agents for mineral binders. |
摘要 |
The thinners are based on water-soluble products of the condensation of naphthalene or alkylnaphthalenes and formaldehyde and are prepared by a process which is characterised in that the viscosity of the reaction mixture during the condensation reaction and after a basic viscosity of 4,000-8,000, preferably 5,000-7,500 mPas, has been achieved is reduced by adding water.
