calcium polyacrylateの例文
- The less stable calcium polyacrylate chains are progressively replaced by aluminum polyacrylate, allowing the calcium to join the fluoride and phosphate and diffuse into the tooth substrate, forming polysalts, which progressively hydrate to yield a physically stronger matrix.
- These polyanions have carboxylate groups whereby cations bind them, especially Ca 2 + in this early phase, as it is the most readily available ion, crosslinking into calcium polyacrylate chains that begin to form a gel matrix, resulting in the initial hard set, within five minutes.
