Q:Can I marinate salted eggs with a plastic bucket?
May notA plastic PVC is often used, it is made of PVC resin, plastic resin increasing agent and anti-aging agent, and non-toxic. But the addition of plasticizer, antioxidant and other accessories are toxic, daily in PVC plasticizer, mainly using terephthalic acid two butyl phthalate two formic acid two ester etc., these chemicals are toxic, lead salt antioxidant stearic acid polyvinyl chloride is toxic.
Q:What does plastic melt mean?
The melt flow rate instrument is a test facility for measuring the melt flow rate of thermoplastics under certain conditions. The melt flow rate is an index to measure the melt flow of plastics. The higher the value, the better the melt fluidity of the plastics.
Q:What does Tupperware cup other7 stand for?
Plastic products recycling logo, made by the relevant institutions of the plastics industry in the United states. The logo will be plastic plastic identification code in the container or packaging, from 1 to 7, so that the public need not bother to learn the similarities and differences of various types of plastic materials, you can simply join the ranks of recycling. Each plastic container has a small identification card - a triangular symbol, usually at the bottom of a plastic container. There are 1~7 numbers in the triangle. Each number represents a plastic container. They are made of different materials, and there are different taboos on using them.
Q:How much is plastic PP5 resistant to cold?
Ordinary homopolymer PP has higher heat resistance, but when it reaches -20 degrees of low temperature, it will not stand, easy to brittle.
Q:What harm does plastic particles do to the body in the factory?
Factory waste affects the respiratory tract for a long time, and reduces local resistance. It can cause local invasion because of decreased immunity.
Q:Is the plastic box good or the glass good?
The glass composition is silica, inert, no oxidation; plastic components are polyethylene, is not good for health. So try to choose the glass bottle. You are the same, the plastic box called do not know if you have not read the instructions carefully, it is not plastic, it is food grade plastic, if not particularly hot stuff hot, harmful substances inside will not cause harm to humans.
Q:EVA plastic products poisonous?
EVA plastic products are non-toxic.Ethylene vinyl acetate copolymer, referred to as EVA. Ethylene vinyl acetate (VA) content in 5%-40%, and polyethylene (PE) compared to EVA due to the molecular chain of the vinyl acetate monomer, thereby reducing the high crystallinity, improved toughness, impact resistance, filler compatibility and heat sealing performance, is widely used in foam material, functional films, packaging mold, hot melt adhesive, wire and cable and toys and other fields.
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:Can I make tea with a plastic cup?
The plastic cups sold in the mall are qualified and unqualified. As consumers, we can only make a simple judgement from the surface of the goods. For example, look at the trademarks, factory name, site, telephone, raw materials, texture, certificate and so on
Q:Plastic products in the injection process should pay attention to what?
When the material is formed, the molten material contacts the cavity surface and the outer layer is cooled immediately to form a low density solid shell. Because of the poor thermal conductivity of plastic, the inner part of the plastic part is cooled slowly to form a large solid layer with high density. Therefore, the wall thickness, cooling slow, high-density layer thickness is large contraction. In addition, the layout and number of inserts have direct influence on the direction of material flow, the density distribution and the shrinkage resistance. Therefore, the characteristics of plastic parts have great influence on the shrinkage size and direction.
