| SMECTONE CLAY |
is a rheological additive for organic indigenously manufactured organic clay derivative is a replacement for the entire Bentone organophilic clay series, which is so far being imported, in large quantities by the paint, grease, tyre and many other industries in India.
|
DESCRIPTION
|
SMECTONE CLAY is an organophilic clay complex formed by the reaction of high molecular weight cationic organic compounds with highly purified montmorillonite substance. It is specifically meant for use as agellant, thickener and antisettling agent for organo-liquid systems.
SMECTONE CLAY rheological additives are specially well suited to the grease, coating, rubber, plastic, and oil-well drilling industries. Besides they have a broad spectrum of application where thickening of organic liquid based systems or emulsification of water- in- oil systems are required. |
INCORPORATION TECHNIQUES
|
SMECTONE CLAY gallants are supplied in the form of dry powder. For full development of their useful properties, the gallants must by thoroughly dispersed so as to get complete separation of the minute ultimate particles. The required dispertion is obtained by using a combination of the forms of energy described below: |
| |
| 1. Mechanical Shear Action: |
|
Milling, grinding and stirring provide mechanical shear action, a few examples of
which are detailed as under |
| Roller Milling |
Highly efficient for preparing master batches of SMECTONE CLAY gelling agents in typical vegetable oils, low volatility solvents, epoxy resins, polyesters, etc. |
| Pebble Milling |
|
Very useful for dispersion of the SMECTONE CLAY gelling agents in cases where solvents are too volatile, too fluid or too corrosive for a roller mill. |
| Colloid Milling |
Particularly useful for producing SMECTONE CLAY gels where addition of polar additive is not permissible and where relatively high melting materials such as waxes and asphaltic compounds are to be gelled.
|
| High Speed Stirring |
Employable, though use of milling techniques are preferable to stirring. In cases where milling techniques are not possible or practical to use, mechanical stirring can be employed, keeping in mind that the stirring equipment should be capable of developing a high rate of shear, as in stirring there is always a tendency to develop lumpy gels. |
