How to test dibutyl phthalate (DBP)?
The higher the oil absorption value, the better the strengthening performance. How to test DBP?
○ Method (The testing sample should be dried at (105±2)°C for 1.5h before testing.Weigh dry sample 1g (precise to 0.001g), placed on a glass plate, began to drop at a faster rate of dibutyl phthalate.)
Which liquid is a suitable alternative to DBP measurement?
Out of different tested liquids, like linseed oil, paraffinic oil, etc., DOA was found as the most suitable alternative which leads to evaluated absorption numbers close to DBP measurement.
How is the final absorption value of dibutyl phthalate calculated?
The final absorption value (cm3/g) is calculated based on the consumption of dibutyl phthalate absorbed in the 1g sample. Note: The difference between the two test results must not exceed 0.13 cm3/g. Dosage of precipiated silcia in dif...
How do you determine a DOA absorption number?
The determination of the DOA absorption number is performed by means of an absorptometer which is equipped with a torque measurement and processing system. The DOA absorption number provides an indication of the void volume formed by the aggregates and agglomerates of the pigments and extenders.
How to determine liquid absorption capacity of a pigment and extender?
This International Standard specifies a general method for determining the liquid absorption capacity of a pigment and extender by using di- (2-ethylhexyl) adipate (DOA, CAS 103-23-1). The determination of the DOA absorption number is performed by means of an absorptometer which is equipped with a torque measurement and processing system.
Is there a suitable alternative for DBP and DOP?
The search of a suitable alternative for DBP and DOP, especially for measuring the absorption capacity of polar pigments and extenders, like silica, calcium silicates and sodium aluminium silicates has been carried out in a task group of the Association of Synthetic Amorphous Silica Producers (ASASP) between 2004-2008.
