Plastic Technology for Automotive Modules

With the rapid development of plastic products in the world and the increasingly sophistication of plastic technology, rotational moulding (RM), has become the most practical and irreplaceable way of producing the large and super large containers like tanks, tank, etc. Compared with injection moulding and blow moulding, RM has the characteristics of low cost and easy-to-use, and its application has been extended into many domains. The principle of rotational moulding and comparison of raw material by the requirement of rotational moulding is introduced. The paper emphasizes the introduction of state-of-the-art of RM equipment; also it points out the development of RM.

Plastic Technology

Insulation systems of building structures involve the solution of the following group of tasks: creation of favorable conditions for the work of structural elements and construction as a whole; optimization of heat losses through the insulation shell; creation of comfortable conditions in the room. Such a system would function normally if effective thermal insulation, including polyethylene, were used. The price of polyethylene foam can be reduced without prejudice to the properties in the case of the use of secondary polyethylene foam. The article presents the results of experimental studies, the purpose of which is to optimize the composition of polyethylene foam with the addition of secondary polyethylene, the formation of methods of selection of its composition and the development of systems for the application of products based on polyethylene foam. The article presents the main provisions of the method of analytical optimization, which allows to significantly reducing the material and time costs of processing the results of the experiment. The article deals with aspects of the implementation of construction systems using products based on polyethylene foam in terms of minimizing heat loss through the contact areas. Mandatory criteria for the construction and implementation of insulation systems are safety conditions, including both structural safety (including maintenance-free cycle) and fire safety.
