Q:What are the main raw materials used in plastic products?
Molding performance 1. amorphous material, medium mobility, moisture absorption, must be fully dry, surface requirements of the plastic parts must be prolonged preheating, drying 80-90 degrees, 3 hours2., should take high material temperature, high mold temperature, but the material temperature is too high, easy to decompose (decomposition temperature is >270 degrees). For the higher precision plastic parts, mold temperature should take 50-60 degrees, for high gloss, heat-resistant plastic parts, mold temperature should take 60-80 degrees3, to solve the water to increase the liquidity of the clip, material, high temperature, high modulus to temperature, or change into the water level method.4, such as forming heat-resistant or flame retardant materials, the production of 3-7 days later, the mold surface will remain plastic decomposition, leading to the surface of the mold shining, the need to clean the mold in a timely manner, while the mold surface to increase the exhaust position.
Q:What does PPE mean in plastic products?. Polypropylene or polyethylene, for example, or something else?
Poly (phenylene oxide) (PPE) is a kind of high performance thermoplastic engineering plastics. It has excellent electrical and thermal resistance. In order to adapt to some special occasions, such as copper clad laminate industry, South Africa should be modified as thermosetting material.
Q:What is the difference between plastic raw materials and engineering plastics?
Plastic is resin and filler, so it is usually granular. Raw materials too. Only a few powdery.
Q:Is chlorine dioxide corrosive to plastic products?
Chlorine dioxide is a strong oxidizing agent which can corrode ordinary plastics.
Q:What kind of material do ordinary plastic cups have?
Plastic, glass, metal, etcPlastic cups commonly used materials are glass and AS plastic space two. Space glass also called PC engineering plastics, is widely used in the world, is the main component of polycarbonate. This material lightweight, durable, with insulation, extensibility, dimensional stability, chemical corrosion resistance and high strength, heat resistance with excellent cold resistance. Also has the advantages of self extinguishing, flame retardant, non-toxic, can be colored, and the disadvantage is the lack of hardness than metal, which leads to the appearance of it is easy to scratch
Q:What is the plastic bottle used to make after crushing?
Plastic is a component of polymers, which has a thermal reshaping, that is, heating the plastic, turning it into a liquid, re plasticity, producing new plastic bottles, or other plastic products!
Q:How do plastics weld?
Bonding can achieve good performance and good quality joints, but it is difficult to operate. It needs careful preparation of joints and surfaces, and it is very slow and unsuitable for mass production. The welding is economical, simple, fast and reliable, and can form static strength close to the parent material. Therefore, it is suitable for mass production, and has gained more and more extensive application in the automobile industry. The level of plastic welding technology has become one of the marks to measure the level of automobile production technology and new material development.
Q:What is the difference between plastic PP1, PP2, PP3 and PP4?
PP4 corrosive gases that contain acids, bases, and chemicals. PP5 high impact, toughening, weathering,.PP6, heat aging. PP6 applications: air conditioning systems. PP7 good chemical resistance, good liquidity, medium heat resistance, can be used in home appliances, automotive applications, industrial applications. PP8 high heat resistant. PP9 for automotive impeller and so on. PP10 high rigidity, high heat resistance, high gloss, high definition, used in food containers.
Q:How to make plastic shrink?
The shrinkage of plastic is the percentage of the size of the plastic parts at the molding temperature and the size of the mold after being removed from the mold and cooled to room temperature. It reflects the extent to which plastic parts are removed from the mold and cooled to a reduced size.
Q:What harm does it take to eat hot food with plastic?
Some plastic raw materials are non-toxic, in the manufacture of plastics in the process of adding toxic benzene, alkene and other substances. Plastic bags of particularly deep color, such as black, red and dark blue, are reprocessed with recycled plastic. They are very harmful to the human body and can not be used to import food.
