What machinery and materials are needed for the production of disposable plastic cups?
PP is crystalline polymer. PP is the most common plastic, and the density is only 0.91g/cm3 (smaller than water). In general plastics, PP has the best heat resistance, and its thermal deformation temperature is 80-100 DEG C and can be boiled in boiling water. PP has good stress cracking resistance and has a high bending fatigue life, commonly known as "fold gum"". PP products are light, tough and chemical resistant.
The material required is PP, which is polypropylene.The machines needed are injection molding machines, shredders and dryers.PP plastic, chemical name: polypropylene, specific gravity: 0.9-0.91 g / cubic centimeter molding shrinkage: 1.0-2.5% molding temperature: 160-220 DEG C.
Injection molding machine, also known as injection molding machine or injection machine. It is a thermoplastic or thermosetting plastic plastic molding mold made of plastic products of all shapes of the main molding equipment. The injection molding machine heats the plastic, applying high pressure to the molten plastic to make it crack and fill the mold cavity.Crusher is a large size of solid materials crushed to the required size of the machine. The crusher is composed of coarse crushing, fine crushing, pneumatic conveying and so on. It achieves the purpose of crushing in the form of high-speed impact. The use of wind power as a single powder eliminates traditional screening procedures.
The dryer is moving in the same direction in the process of system design with the temperature reducing water vapor return material prepared to go back to the problem; in the process of drying, hot air flow from the tail to move forward, fully contact with the material, the heat conduction, convection and radiation heat transfer and make full use of heat energy; will be passed directly to the material, the material in the water the cylinder has been evaporated, inlet draught device will flow out of a large number of moisture, moisture, prevent dust pollution two efflux caused by internal spiral; stirring, sweeping, copy board, promote the movement of materials, complete the whole drying process; inverse spread guide avoid dehydration, reduce duplication of drying process.
