- Naphthalene sulfonates are used in preparation of naphthalene sulphonated
formaldehyde (NSF) which is used in polymer-concrete admixtures to neutralize the surface charge on cement particles in enhancing water tied up in the cement agglomerations, and thereafter, in reducing the viscosity of the paste and concrete.
Furthermore, the offerings of global Superplasticizer Market can be categorized into different types such as Lignosulphonates, and Sulphonated
Melamine Formaldehyde (SMF) among other types of superplasticizer that offer different properties to the concrete.
In our previous studies, the bioactivity of PEEK was increased via sulphonation and deposition of HA crystalline particles on the sulphonated
layer [11, 12].
naphthalene formaldehyde is used as a plasticizer.
Zderadicka, High Performance Liquid Chromatography-Mass Spectrometric Analysis of Sulphonated
Dyes and Intermediates, J.
 Due to recent reports on improvement of cell response to sulphonated
poly(Aryl ether ketones) form the basis of the current study.
Imports of Acyclic Alcohols, Sulphonated
, Nitrated and Nitrosated Derivatives has fallen month on month basis by -13.87%.
The superplasticizer (a commercial sulphonated
melamine formaldehyde polymer) with relative density of 1.15 was employed to achieve good workability.
When peroxide bleaching is done using non-ionic surfactants, whiteness aspects are much better due to the absence of yellow coloured sulphonated
It is comprised of a surfactant system (including an alkox-ylated nonionic surfactant, a sulphated or sulphonated
anionic surfactant; and a neutralizing co-surfactant); a thickener or mixture thereof; a chelant or mixture thereof; a solvent selected from the group consisting of ethers having from 4 to 14 carbon atoms, diethers having from 4 to 14 carbon atoms, glycols, alkoxylated glycols, alkoxylated aromatic alcohols, aromatic alcohols, alkoxylated aliphatic alcohols, aliphatic alcohols, C8-C14 alkyl hydrocarbons, C8-C14 cycloalkyl hydrocarbons, C8-C14 alkyl ha lohydrocarbons, C8-C14 cycloalkyl halohydrocarbons, C6-C16 glycol ethers, and mixtures thereof; and water.
Super--plasticisers now are organic substances that, by their chemical composition, may be classified into the following groups: sulphonated
naphthalene formaldehydes, sulphonated
melamine formaldehydes, modified lignosulphonates, polycarboxylates and polycarboxylate ethers (Usherov-Marshak 2005; Erdogu 2000; ACI COMMITTEE 212 1989; Mosquet et al.
