1. Beginning, Structure, and Molecular Style

(Animal Protein Frothing Agent)
Pet protein-based lathering representatives are derived mainly from hydrolyzed keratin or collagen sourced from abattoir spin-offs such as hooves, horns, bones, and hides.
Via controlled alkaline or enzymatic hydrolysis, these structural healthy proteins are damaged down into amphiphilic polypeptides abundant in amino acids like glycine, proline, and hydroxyproline, which have both hydrophilic (– NH TWO,– COOH) and hydrophobic (aliphatic side chains) functional groups.
This double affinity allows the molecules to adsorb effectively at air– water interfaces during mechanical oygenation, lowering surface tension and supporting bubble formation– a crucial requirement for generating uniform cellular concrete.
Unlike artificial surfactants, pet healthy protein frothing representatives are eco-friendly, non-toxic, and exhibit excellent compatibility with Rose city concrete systems as a result of their ionic nature and moderate pH buffering capacity.
The molecular weight distribution of the hydrolysate– generally in between 500 and 10,000 Da– directly influences foam security, drainage price, and bubble size, making process control during hydrolysis essential for consistent performance.
1.2 Foam Generation Device and Microstructure Control
When watered down with water (typically at proportions of 1:20 to 1:30) and introduced into a foam generator, the healthy protein service forms a viscoelastic film around entrained air bubbles under high-shear problems.
This movie resists 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 strengthened with hydrogen bonding and electrostatic interactions.
The resulting foam displays high development proportions (usually 15– 25:1) and low drain rates (
