Process design of annual output of 100000 polyethylene blow molding barrel
Design general description:The design task source is based on the design issues given by the instructor, to choose their own graduation design topics for their own major. The design standards are based on the requirements of the task book for this graduation design. According to the book, the contents of this design are plastic blow drum, and its capacity is 30L, the material is HDPE, the color is white, the wall is 5 (-2, +3) mm. The design principle is to comprehensive use of what they have learnt knowledge and combined with production practice and reality to independently design, in line with the requirements of the design task, in line with the school of design in the link of graduation requirements.
The introduction tells about the increasing share of blow molding products in the market and a certain percentage of growth every year, which can be pided into packaging containers and industrial and structural products.. The plastic variety of polyethylene is the earliest product of the plastic hollow molding material, and it is also the most popular variety.. As one of the PE, HDPE has broad market prospects.. The characteristics of HDPE is excellent hardness, tensile strength and creep, good impact toughness, electrical insulation, tear resistance, low temperature resistance, etc., with good chemical stability and resistance to organic solvent, acid, alkali and salt. HDPE of the hollow products are pharmaceutical bottles, beverage bottles, cosmetics bottles, detergent bottles, fuel tanks, tanks, etc., and its products have various shapes.
Formulation design part tells the story of the raw materials according to the requirements of the task book for HDPE, due to the high density polyethylene (HDPE) with high rigidity and toughness, excellent mechanical properties and heat resistance, also has good solvent resistance, resistance to steam permeability, processing performance, so consider the formula does not require the addition of plasticizer. Due to product belongs to a hollow container, so the choice of formula should be considered first products of impact resistance, aging resistance performance and performance in outdoor use, secondly if used for filling detergent, bleaching powder etc., also need to consider product antistatic performance, so to choose impact modifier, antioxidant, light stabilizer, antistatic agent and so on. Finally select the corresponding color masterbatch products. HDPE itself performance is excellent, there is no need to add too many additives, so the number of additives and the number of additives is not much. 年产10万只聚乙烯吹塑桶车间工艺设计(2):http://www.751com.cn/huaxue/lunwen_23042.html
