Plastic household products are general designation of household articles which is made of plastic as the main raw material.
Plastic household products, including the production of general ingredients, molding, mechanical processing, bonding, modification and assembly, etc..Household plastic products have been formed as a product or semi products, after the four processes, it is also known as the two processing of household plastic products.
The forming of plastic household products is the key link in the processing of domestic plastic products.The various forms of plastic (powder, granular, solution or dispersion) made the required shape of plastic products or blank.As many as 30 kinds of molding method. Its choice is mainly determined by the type of domestic plastic products (thermoplastic or thermosetting), the starting shape and the shape and size of the product. Household plastic products processing, thermal plastic household plastic products commonly used methods such as extrusion and injection molding, calendering, blow molding and thermoforming.
Plastic household products have a lighter weight. The household plastic products are light materials, and the relative density is between 2.2 and 0.90.
Plastic household products have good chemical stability.For acid, alkali and other chemical substances, the vast majority of household plastic products have good corrosion resistance.Especially, commonly known as king of household plastic products of PTFE (F4) and its chemical stability even better than gold, put boil ten hours in the "aqua" will not degenerate. Because F4 has excellent chemical stability, it is an ideal corrosion resistant material. Such as F4 can be used as a material for conveying corrosive and viscous liquid pipelines.
Plastic household products is a poor conductor of heat, it has the effect of noise reduction, shock absorption.
The mechanical strength distribution of plastic household products is wide, it has a higher ratio of strength.Some household plastic products as hard as stone, steel, some soft such as paper, leather; from the household plastic products hardness, tensile strength, extension rate and impact strength and mechanical properties, wide distribution, great choice. Domestic plastic products also have obvious shortcomings, such as easy to burn, the stiffness is not as high as metal, poor aging resistance, heat resistance and so on.
