Stimuli-responsive micro-reservoirs for release of encapsulants

This invention relates to polymer-based partially-open, hollow reservoirs in the nano-size to micro-size range that encapsulate an additive, which can be released from the reservoirs using specific event stimuli such as reduction-oxidation and voltage change, or at will, using the same stimuli. This invention also relates to method preparing such reservoirs, and for releasing the additive. This invention further relates to matrix that comprises such reservoirs and the method of preparing such matrix. This invention also relates to applications, for example in corrosion inhibition, lubrication, and adhesion, that benefit from using such a controlled release of an additive.

METHOD FOR THE CONTINUOUS PRODUCTION OF A MIXTURE WITH A PRE-DEFINED RATIO OF FULLY COLORED AND NON-COLORED FERTILIZER PARTICLES AND SYSTEM AND USE THEREOF
20230002292 · 2023-01-05 ·

A method for continuous production of fully colored and non-colored fertilizer particles having a median size of about 1 to 6 mm, with a predefined ratio of the fully colored and non-colored fertilizer particles, starting from a stream A of non-colored fertilizer particles. The method includes continuously separating the stream A of non-colored fertilizer particles into a stream C of non-colored fertilizer particles and parallel streams B1, B2, . . . Bn of non-colored fertilizer particles in a predefined ratio, continuously coloring the non-colored particles from the parallel streams B1, B2, . . . Bn with a non-rub-off coloring agent, such that the particles become fully colored, continuously joining the parallel streams B1, B2, . . . Bn, including the fully colored fertilizer particles, with the stream C of non-colored fertilizer particles downstream, thereby obtaining the mixture of fully colored and non-colored fertilizer particles, and, optionally, processing the mixture of fully colored and non-colored fertilizer particles.

PolyHIPE-based substance-releasing systems

System and method for manufacturing polymer coated controlled release fertilizers
11591276 · 2023-02-28 · ·

A system and method are provided for manufacturing the polymer-coated fertilizers with a controlled release in a single pass. The system has a feeding mechanism connected to a first chill roll to supply the articles to the first cavities provided on the first roll to store and hold the articles. A first machine produces and applies a first polymer film on the articles held in the first chill roll to coat the articles partially with the first polymer film. The partially coated articles are transferred to a second chill roll placed at a side or on a top of the first chill roll. A second machine produces and applies the second polymer film on the partially coated articles in the second chill roll so that the articles are encapsulated by the first and second polymer films. A collector mechanism receives the encapsulated articles from the second chill roll.

Drying a coating using electromagnetic radiation or heating of drum

Methods, systems, and apparatuses for coating a material by contacting the material with a coating material and a solvent are disclosed herein. The coated material can be obtained by evaporating the solvent: by heating the coated material directly or indirectly with electromagnetic radiation; by heating with heat generated from a heat source that heats an internal container for the material to be coated and/or coated material; and/or in an interior volume of a coating container having a side wall, by heating a portion of the side wall of the coating container and/or internal container with a heat source that is positioned outside of the interior volume of the coating container.
