Polymer materials are materials composed of compounds with relatively high molecular weight.Divided into natural and syntheticTwo types, for exampleThe natural materials we come into contact with, such as cotton and natural rubber, are composed of polymer materials，SynthetichaveChemical fibers, plastics, rubber, etc.Polymer materialshaveUnique structure and easy to modify and process characteristics.Application of Polymer MaterialsVery extensiveSynthetic rubber, synthetic fibers, and plastics all belong to polymer materials. Applications are found in fields such as communication, electronics, healthcare, chemical engineering, aviation, and aerospace. The chemical industry is the most widely used, with latex, coatings, and other materials composed of high molecular weight polymers.Entering the era of technology, enterprisesThe freeze-drying technology of polymer materials utilizes the principles of industrial freeze-drying machines to manufacture polymer materials for special applications.

At present, freeze-drying of polymer materials is applied in many fields,Shanghai Tianfengpass throughThe principle of polymer material freeze-drying machine, according toThe characteristics of the material need to be adoptedFZGSeries freeze dryerPerform -50 ℃ pre freezing crystallization. After the specified pre freezing time, start the vacuum pump to form a vacuum environment. When the pre pumping reaches the required standard vacuum value and runs for the required time, enter a drying and analytical drying process. During the process, the water replenishment device needs to maintain a condensation temperature of -50~-70 ℃. The partition is controlled by a curve, and the vacuum degree is fine tuned between 15~30pa. After drying, obtain a polymer material with a moisture content of about 3%. The entire process is controlled by a microcomputer and computer, and can be started with one click after pre-set programs, which is in line with industrial operation management.FZGThe material tray, box, partition, condenser, etc. of the series freeze-drying machine are made of 304 or 316 stainless steel to avoid corrosion of equipment by polymer materials. During the drying process, in order to prevent material aggregation and discoloration after drying, special freeze-drying processes are required to control the characteristics of the material. This can be achieved throughFZGFreeze dryer engineers provide guidance or training on operation and offer technical solutions.
