Apparatus for passive mixing of a multi-phase (ic) flow or hydrodynamic performance that is housing a conduit / tube, which is a channel extending internally from the fluid inlet to the outlet ports, comprising axially stacked plurality of static mixers possessing structural elements or mixing elements (possessing structural elements on their inner walls), that are responsible for continuous splitting, and combining of the flow through the conduit, bringing about enhanced mixing of contents of the flow, mass-transfer, and heat transfer. The structural elements bring about enhanced mixing of multi-phasic systems passing through the conduit such as liquid-liquid, liquid-gas-liquid, and systems comprising immiscible and viscous liquids. The mixing elements or structural elements are responsible for splitting of flow into sections of multiple streams, followed by forced recombination of the multiple streams which is responsible for the equitable dispersion of individual components of the multiphasic flow, thereby enhancing the mixing of the flow.

This invention relates to the field of polymer processing aids, specifically to a rheology modifier for low-polarity organic media such as white oil, mineral oil, and alkane solvents. This invention aims to overcome the technical shortcomings of existing oxidized polyethylene products and provide a synthetic route. This route involves moderate and controllable preliminary oxidation of polyethylene raw materials, followed by quantitative and targeted deep chemical modification of the generated oxygen-containing groups, thereby constructing a "comb-like" polymer structure with both excellent oil compatibility and strong hydrogen bonding ability. Firstly, this invention provides a comb-like structure rheology modifier for low-polarity systems. Secondly, this invention provides a method for preparing the above-mentioned rheology modifier. Thirdly, this invention provides the application of the above-mentioned rheology modifier in compositions using white oil, mineral oil, synthetic alkanes, or mixtures thereof as the continuous phase. Fourthly, this invention provides a low-polarity fluid composition. Through precise secondary chemical design of oxidized polyethylene, this invention successfully transforms a mediocre wax product into a high-performance rheology modifier with a well-defined structure, high efficiency, transparency, and ease of use, perfectly solving the dual requirements of low-polarity systems for excellent rheological properties and appearance quality.

A method and apparatus for a two-piece capsule configured to expel air and reduce bubbles within a composition. The invention features a capsule with a cap and body, where the cap includes an insert with a dome shape designed to compress against the meniscus of a fluid composition or powder. This compression minimizes trapped air and enhances the capsule's structural integrity and longevity. Additionally, the capsule may employ a sealing element to prevent leakage, ensuring a stable, bubble-free environment for the contents. The capsule's design allows for efficient filling and reduces oxygen exposure, thus preserving the quality of the encapsulated material. The invention can be used for both powder and liquid encapsulations, enhancing shelf life and stability by significantly reducing internal air and maximizing fill volume.
