Abstract:
A method of optimizing an autoclave volume utilization includes, in an exemplary embodiment, determining process parameters of an autoclave (10); modeling an autoclave configuration to determine airflow patterns in the autoclave, temperature variation throughout the autoclave, and the distribution of turbulent intensity in the autoclave; and modifying the autoclave configuration with hardware changes to the autoclave to alter the airflow patterns in the autoclave. The method also includes modeling the modified autoclave configuration to determine modified airflow patterns in the autoclave, modified temperature variation throughout the autoclave, and the modified distribution of turbulent intensity in the autoclave; and modeling the modified autoclave configuration with parts (24) to be cured in the modified autoclave configuration to determine an arrangement of parts that maximizes the number of parts in the autoclave that meet predetermined cured properties of the parts.

Abstract:
The invention relates to a pressurised appliance (10) comprising a chamber (34) for receiving a liquid content, and a cover (16) for closing the chamber in a closing position, said cover comprising a sampling tip (50), said tip comprising a cannula (52) that can be in contact with the content when the cover is in the closing position, the sampling tip having at least one closable opening (58) which allows, when the cover is in the closing position thereof and said opening is open, the maintenance of a pressure balance between the inside of the cannula and the inside of the chamber, and, when the cover is in the closing position thereof and said opening is closed, the sampling of the content via the cannula.
Abstract:
A high-gravity rotating bed device, comprising a motor (10), a rotor (20) and a housing (30). The rotor (20) and the motor (10) are entirely arranged within the housing (30). A load-bearing plate (31) is provided within the housing (30). The load-bearing plate (31) divides the housing (30) into a reaction chamber (32) and a balance chamber (33). The motor (10) is arranged within the balance chamber (33). A transmission shaft of the motor (10) passes through the load-bearing plate (31) and is fixedly connected to the rotor (20) arranged within the reaction chamber (32). A gas inlet (34), a gas outlet (35), a liquid inlet (36) and a liquid outlet (37) are arranged on the housing (30). An externally communicating pipeline (331) is arranged on the balance chamber (33). Also disclosed is an application of the present high-gravity rotating bed device under high-pressure conditions in operations such as mixing, transferring and reacting.

Abstract:
The present invention discloses a pump-type autoclave system and a providing method for steam and pressure thereof, wherein the pump-type autoclave system comprises an autoclave, a steam providing device and a compressor, said steam providing device comprises a water storage container and a heating device used for heating said water storage container, said water storage container, the compressor and the autoclave are connected through a pipeline to form a closed loop, an inlet of the compressor is connected with a steam output port of the water storage container, an outlet of the compressor is connected to a steam input port of the autoclave, and a condensate water drain outlet of the autoclave is connected to the water storage container. The present invention uses the compressor to depressurize an intermediate-low temperature water source to obtain steam, and the steam is pumped into the autoclave and condensed to release heat to obtain corresponding temperature and pressure. Since the present invention fully utilizes a great amount of low-cost intermediate-low temperature heat sources obtained from natural, industrial or living waste heat to provide needed high temperature, steam and pressure to the autoclave system, the energy is saved.
Abstract:
A method of preparing and rapidly curing a composite material having a thin cross section. The composite material includes a mixture of solid particles, at least some of which are a material that reacts with C0 2 , such as a silicate, for example Wollastonite. The green material is prepared by mixing the solid components with a liquid such as water to form a slurry, and forming green bodies by placing the slurry in forms. The green bodies are reacted with C0 2 to form cured composite materials having thin sections, in the range of 10 to 15 mm. Curing in periods of 6 hours has been demonstrated.
Abstract:
The present disclosure provides methods and apparatuses estimating casting throughput during casting process to provide polyamide pellets. The method of estimating casting throughput of an extruded polyamide polymer comprises measuring an amount of casting water flowing in to a casting apparatus typically from two or more locations, measuring the temperature of the casting water flowing in, and measuring the temperature of the casting water flowing out. Additional steps include calculating a heat transfer between the casting water flowing in and the casting water flowing out using the measured amount, and correlating the heat transfer to the casting throughput.
