New polypropylene material for making barrels in dishwashers instead of stainless steel

2019-05-31

A new type of polypropylene material has recently been developed that can replace the stainless steel material in the barrel of the dishwasher. In addition to the stability required, the mechanical properties are also checked. Therefore, a fall test is required, that is, the fully assembled dishwasher falls from a height of half a meter to the concrete floor, and the inner drum of the dishwasher must be intact. Due to the short design development cycle required, a dynamic computer simulation program was used to simulate the fall test. These dynamic calculations and simulations greatly shortened development time and reduced development costs. Replaces stainless steel as a dishwasher in the barrel material home appliance technology. The material properties, processing properties and design properties together form the final product. Each specific application has its own special requirements. The question is how to determine these requirements and find the most cost-effective material solution that meets the requirements.

For the inner barrel of the dishwasher, the material must meet the following requirements: high rigidity, high impact strength, good surface quality, good scratch resistance, good contact with hot water or builder, no discoloration, high thermal deformation resistance, high stabilizer resistance Good stability and good dimensional stability. Based on the above requirements, the newly developed polypropylene material has developed a mechanical property of polypropylene material that can replace the inner barrel of stainless steel. It is a new polypropylene material filled with talcum powder. It has excellent impact resistance, good rigidity and good stability to builders, hot water and cleaning agents.

Filler selection In order to achieve specific material requirements, fillers must be added to the polypropylene. For the filler, the particle size distribution, color, hardness, specific gravity, aspect ratio, surface modification, etc. should be considered. Many factors. Among the many plastic fillers, we have chosen talc as the active filler because the talc-filled polypropylene compound has higher resistance to thermal deformation than the calcium carbonate-filled compound.
