Abstract

Polylactide (PLA) parts can be crystallized via two procedures. In the first procedure, i.e. a 2-step post-mold annealing process, the complete crystallization of PLA parts can be done after molding in a secondary operation called as post-mold annealing to make higher heat-resistant PLA parts. There are limitations to this 2-step operation, namely, a) warpage of parts with complex geometries, and b) scaling up higher production volume times. In the second procedure, i.e. 1-step in-mold annealing process, the complete crystallization of PLA parts can be done in the mold itself by holding the temperature of the mold at the crystallization temperature of PLA which is about 100° C. The 1-step in-mold annealing process using a masterbatch blended with neat PLA results in a highly crystalline article produced in a significantly lower cycle time.

Abstract

2 and tensile elongation of greater than 12%. This exceptional improvement observed in the PLA blend is a synergistic effect of the addition of the difunctional flexible polymer of the copolymer and thermal annealing. The improvement observed in the mechanical properties with high PLA homopolymer content above about 90 to about 98 wt. % is unusual and results in an increased scope of molding and thermoforming applications. The annealed PLA-copolymers having a difunctional flexible middle segment have also been found to have improved notched Izod impact properties.

The invention relates to a biodegradable and compostable blend of polylactic acid, a compostable polyester with or without carbon based biocontent, polyethylene glycol, and optionally an inorganic talc filler that have greatly increased elongation, flexibility, and tensile toughness as measured by tensile test ASTM D638-10. These blends of PLA with 5-30% of said polyester, about 10% PEG, and about 5% of an inorganic talc filler unexpectedly increased the elongation to 750+ % for molded test bars. Additionally, 4 mil films showed a max tear strength of about 1200 gms (in MD) and 900 gms (in TD) measured by ASTM D1922-09 while maintaining other preferable properties.

The sleeves are permeable to vapors emitted by the solid VCI compounds and flow through the pipe to a perforation where they are admitted into an area beneath a storage tank so that they can contact the tank bottom (soil side) and protect the same from corrosion. Alternatively, solid SCI compounds can be used in combination with VCI compounds. The corrosion protection system is designed to be used with aboveground storage tanks. This includes, but is not limited to, single bottom tanks: newly installed or existing tanks undergoing bottom replacement or installation of double bottoms. These tanks are located on substrates such as the compacted soil/sand or hard substrates such as concrete, bitumen mixtures and asphalt where channels can be cut into the substrate for installation of the pipe system.

Abstract

A method and apparatus for the corrosion protection of tank soil side bottoms is achieved by providing equipment to an existing storage tank as by installing a chime delivery system about the perimeter of the storage tank bottom plate, and introducing an appropriate amount of a corrosion inhibitor into the chime delivery system, whereby the corrosion inhibitor is readily admitted into the spaces between the substrate and the tank bottom plate. The system avoids any refurbishment of the tank and allows for easy introduction and replenishment of inhibitor without interruption of tank operations. The system also does not require any renovation of the tank, and does not require any replacement of the tank bottom plate panels.
