(Animal Protein Frothing Agent)
Animal protein-based lathering agents are acquired mostly from hydrolyzed keratin or collagen sourced from slaughterhouse by-products such as hooves, horns, bones, and hides.
Through regulated alkaline or enzymatic hydrolysis, these architectural healthy proteins are broken down right into amphiphilic polypeptides rich in amino acids like glycine, proline, and hydroxyproline, which have both hydrophilic (– NH â‚‚,– COOH) and hydrophobic (aliphatic side chains) useful teams.
This double fondness enables the particles to adsorb effectively at air– water interfaces throughout mechanical oygenation, reducing surface area tension and supporting bubble development– a crucial requirement for generating uniform mobile concrete.
Unlike artificial surfactants, animal healthy protein foaming representatives are biodegradable, safe, and show superb compatibility with Rose city cement systems as a result of their ionic nature and modest pH buffering capability.
The molecular weight circulation of the hydrolysate– generally between 500 and 10,000 Da– straight influences foam security, water drainage price, and bubble dimension, making procedure control throughout hydrolysis vital for consistent performance.
1.2 Foam Generation Device and Microstructure Control
When watered down with water (commonly at ratios of 1:20 to 1:30) and presented into a foam generator, the healthy protein solution develops a viscoelastic film around entrained air bubbles under high-shear problems.
This movie stands up to coalescence and Ostwald ripening– the diffusion-driven growth of bigger bubbles at the cost of smaller sized ones– by creating a mechanically robust interfacial layer reinforced through hydrogen bonding and electrostatic communications.
The resulting foam displays high growth ratios (typically 15– 25:1) and reduced drain rates (
