Process for continuously manufacturing microcapsules. |
摘要 |
<p>In a process for continuously manufacturing microcapsules, capsule nucleus material and wall formation chemicals are mixed in a conduit (6) before being passed through an emulsification mill (7). The resulting emulsion flows without turbulence through an encapsulating conduit (8) which passes through a water jacket reactor (9) maintained at a single elevated temperature and emerges from the conduit as a dispersion of finished microcapsules. The wall formation chemicals are (a) methylol melamine or etherified methylol melamine or low molecular weight polymers thereof or a combination of these materials and (b) one of a specified class of negatively-charged polyelectrolytes. The resulting capsules may be used in pressure-sensitive copying materials.</p> |
