Storage method of polypropylene composite material

Abstract

The invention belongs to the field of polypropylene composite material production, and particularly discloses a storage method of a polypropylene composite material. The storage method comprises the steps of drying, packaging, storing and maintaining, wherein the drying step comprises primary drying and secondary drying. According to the storage method, before packaging, the polypropylene composite material is subjected to double drying treatment, a vibrating screen is combined with a hot air blower, convection drying is conducted on the upper surface and the lower surface, and polypropylene composite material particles can be comprehensively dried; and then a fluidized bed is used for three-stage drying, drying is thorough, the good drying state of the polypropylene composite material entering the packaging link can be kept, and the situation that the interior of the polypropylene composite material is mildewed is avoided. A storage plate with a high storage frame is arranged in a warehouse, so that a polypropylene composite material bag is prevented from being in direct contact with the ground, and the moisture-proof effect is good; and meanwhile, a layer of drying agent is scattered on the ground below the storage plate, so that the polypropylene composite material bag can be kept in a good drying environment, and the storage time of the polypropylene composite material bagis prolonged.

Description

technical field [0001] The invention relates to the production field of polypropylene composite materials, in particular to a storage method for polypropylene composite materials. Background technique [0002] Polypropylene, referred to as PP, is a colorless, odorless, non-toxic, translucent solid substance. Polypropylene (PP) is a thermoplastic synthetic resin with excellent performance, which is a colorless and translucent thermoplastic lightweight general-purpose plastic. With chemical resistance, heat resistance, electrical insulation, high-strength mechanical properties and good high wear-resistant processing properties, etc., polypropylene has been rapidly used in machinery, automobiles, electronic appliances, construction, textiles, and packaging since its inception. It has been widely developed and applied in many fields such as agriculture, forestry, fishery and food industry. [0003] At present, after production and processing, the quality of polypropylene compo...
