Shape-stabilized phase change material are composite energy storage materials composed of phase change materials and polymeric support materials, due to slight packaging and supporting function of polymeric cystic materials, as the core materials, the solid-liquid phase change materials don’t outflow during phase changes and the whole composite material can maintain its original shape and a certain intensity after core materials melt.
American Florida University of Science and Technology has used mixture of fatty acids and short-chain acids, mixture of methyl ester and short-chain acids as phase change materials, respectively, uses the mortar board as the base materials, to prepare phase change wallboard by immersion method.
Research is being carried out gradually, such as, the choice of the phase change materials, thermal analysis, phase change materials combined with building materials and the actual use of phase change wall .

The raw and auxiliary materials are mainly from domestic suppliers, and the usage ratio is shown in Table 2.
The use of phase-change materials in the production of phase-change gypsum plasterboard is the main stage causing eutrophication, which can be improved from the use of phase-change materials to enhance material utilization efficiency and to reduce waste
(4) The transportation process of various raw materials and energy also has a certain environmental impact on the life cycle of the two kinds of gypsum boards; therefore, transportation distance of various raw materials and energy can be optimized or reduced, and symbiotic park of raw materials can be built to reduce the load on the environment.

In this paper, a context-aware materials data integration meta model is presented which is incorporating an advanced materials demand mapping and decomposition mechanism to support fine-grained materials data in the right time for the provision of materials services, based on the analysis of the application context involving the key points and relationships in their manufacturing processes.
Introduction Materials management is important during the process of production management in the enterprises[1].
Context data are defined as any raw materials data values of the relevant entities, which affect the data integrating.
Actually, this is the mechanism for obtaining first-order context information from raw materials data.
