摘要:
An integral three-dimensional article having interstitials therethrough, the three-dimensional article comprises an unconstrained number of axially successive stages. An apparatus and process for molding such a three-dimensional article are also disclosed. The apparatus has members extending into a mold cavity, each member having access to the periphery of the mold cavity. Each stage may nest within an adjacent stage. The nesting may be accomplished by having the end of one stage be convex, while the mating end of an adjacent stage is complementary and concave. The article may be useful as a static mixer, heat exchanger, etc.
摘要:
An extrusion/coating die. The die has an internal cavity and one or more static mixers in the die cavity. The static mixer fills the die cavity at its respective cross section. The die may also have one or more auxiliary inlets for separately admitting material/energy to the die.
摘要:
A structured liquid composition having a liquid matrix having water and a fibrous network structurant, the fibrous network structurant having a non-polymeric crystalline hydroxyl-functional materials; a bacterial cellulose network; and mixtures thereof; and an encapsulated active. The encapsulated active is suspended within the liquid matrix of the structured liquid composition such that the encapsulated actives do not undesirably sink, float, or collect in any discrete portion of the composition. Further, the structured liquid composition can be in the form of a raw material such as an encapsulated active slurry, in the form of an additive such as a laundry additive, and as a consumer end product. In one embodiment, the encapsulated active is a perfume microcapsule.
摘要:
A static mixer having one or more stages and/or elements. The static mixer may be scaled from bench size to any commercially desired size. During scale-up the surface area to void volume ratio is maintained constant. Maintaining this ratio constant may be accomplished by increasing the number of bars in each element of the static mixer.
