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 about the outlook for plastic particles?
A medium-sized plastic woven bag factory annual consumption of more than 2000 tons of recycled polypropylene particles, even individual small factories are required minimum annual consumption of hundreds of tons; a medium-sized shoe factory in need of polyvinyl chloride (PVC) recycling 2000 tons of recycled plastics enterprise...... particles of huge demand, provide a broad market space for enterprises and individuals to establish the regeneration of the waste plastic particles factory. As a result, recycled plastic particles do not worry about sales.
Q:What kind of plastic bottles can be used again and again?
Subsequently, the reporter found some food containing plastic bottle, was found in the bottom of the bottle is part of digital signs, such as China 550G installed at the bottom of honey bottle labeled "02". However, the reporter also found that many bottles at the bottom without any mark, like master 500ML fresh daily C Coca-Cola 450ML, beautiful fruit juice drink.
Q:Plastic molding is what to do, how the process?
The process is divided into four phases:The first stage, plastic injection. When the melt enters the mold cavity, it meets a lower temperature mold wall, forming a thinner solidification layer;The second stage: gas incidence. The inert gas enters the molten plastic, pushing the center of the uncured plastic into the cavity that is not yet filled;The third stage: gas incidence. The gas continues to flow through the plastic melt until the melt fills the mold cavity;The fourth stage: gas pressure maintaining. Under the condition of holding pressure, the air in the air compresses the melt to supplement the material to ensure the appearance quality of the parts.
Q:Is the resin material of imitation jade handicraft Plastic?
Resin usually refers to softening or melting range after heating. When softening, it tends to flow under external force. At normal temperature, it is solid, semi solid, and sometimes liquid organic polymer.
Q:How about a bottle of water?
General plastic bottles can only be installed cold water, such as hot water used, it will increase the risk of harm, it is recommended not to use plastic bottles for a long time to drink water.
Q:What are the raw materials used in the production of plastic products?
Bearing cleaning supplies, plastic containers and bath products currently used in supermarkets and shopping malls in the plastic bag is made of this material, can resist high temperature of 110 DEG C, indicating the food use of plastic bags can be used for holding food. Bearing cleaning supplies, plastic containers and bath products can be repeatedly used carefully after cleaning, but these containers are usually not good cleaning, easy residual cleaning supplies, become a breeding ground for bacteria, it is better not to use circulation cleaning is not thorough so.
Q:Can plastics be recycled?
Become soft when heated so as to flow and become hardened by cooling. The process is reversible and can be repeated. Polyethylene, polypropylene, PVC, polystyrene, POM, polycarbonate, etc.. Thermoplastics can be recycled, while thermosetting plastics cannot be recycled.
Q:What plastic sunscreen?
PVC also has titanium dioxide and UV absorbers
Q:What is the difference between plastic PP1, PP2, PP3 and PP4?
PP1 plastic centrifuge tube with PP material production, no toxicity, good chemical resistance and heat aging.PP2.PP3- uses: endoscopy about shell, toolbox, door handle note: the corrosive gas.PP5 weathering heat aging resistance of.PP4 acid composition and chemical composition of high impact toughness, weather resistance, heat aging of.PP6 use:.PP6 the air conditioner system.PP7 good chemical resistance, good fluidity, medium heat resistance, can be used for household appliances, automotive applications, industrial application of.PP8 high heat.PP9 use in automobile.PP10 impeller of high rigidity, high heat resistance, high definition, Ze Gao Guang, used for food containers.
