(Animal Protein Frothing Agent)
Pet protein-based lathering agents are derived primarily from hydrolyzed keratin or collagen sourced from slaughterhouse byproducts such as hooves, horns, bones, and hides.
Via regulated alkaline or chemical hydrolysis, these structural healthy proteins are damaged down into amphiphilic polypeptides rich in amino acids like glycine, proline, and hydroxyproline, which have both hydrophilic (– NH TWO,– COOH) and hydrophobic (aliphatic side chains) useful teams.
This twin fondness allows the molecules to adsorb effectively at air– water user interfaces during mechanical oygenation, minimizing surface area stress and supporting bubble formation– an essential need for generating uniform mobile concrete.
Unlike synthetic surfactants, pet protein foaming representatives are biodegradable, non-toxic, and show exceptional compatibility with Rose city concrete systems because of their ionic nature and modest pH buffering capacity.
The molecular weight distribution of the hydrolysate– typically between 500 and 10,000 Da– directly influences foam security, drain price, and bubble size, making process control throughout hydrolysis crucial for regular efficiency.
1.2 Foam Generation Mechanism and Microstructure Control
When thinned down with water (usually 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 conditions.
This movie withstands coalescence and Ostwald ripening– the diffusion-driven growth of larger bubbles at the expenditure of smaller sized ones– by forming a mechanically durable interfacial layer reinforced with hydrogen bonding and electrostatic communications.
The resulting foam shows high development ratios (typically 15– 25:1) and reduced water drainage rates (
