Q:How do you understand the level of engineering plastics?
LDPE (low density polyethylene): common plastic film, plastic film and so on. High temperature will produce harmful substances, plastic film into the microwave.
Q:White plastic for a long time. Why does it turn yellow?
The plastic box production after or after using for a long time are yellow because the material used in aging, or perhaps because produced after degradation, the most serious of this phenomenon is that some white plastic box, such as some white box, plastic barrels and so on.
Q:What is the difference between plastic raw materials and engineering plastics?
engineering plasticIt's a kind of plastic, and a universal plastic.Like everyday things, what barrels, pots, plastic, etc?.
Q:What happens when plastic gets wet and sticky?
Plastic sticking is the main reason:1, time is too long, leading to aging;2, contact a number of chemicals, the reaction occurred;3, the external environment overheating leads to changes.
Q:How many kinds of plastic materials are there?
There are many kinds of plastics. So far, there are about more than 300 kinds of plastic produced in the world. Many classification methods of plastic, there are two kinds of commonly used: 1, according to the nature of the heated plastic divided into thermoplastic and thermoset plastic molecular structure are linear structure, softening or melting when heated, plastic into certain shape, after cooling and harden. After heating to a certain extent, it softens again and hardens again after cooling. This process can be repeated many times. Such as PVC, polyethylene, polystyrene and so on. Thermoplastic molding process is relatively simple, can be continuous production, and has a high mechanical strength, so the development of very fast.
Q:What harm does plastic particles do to the body in the factory?
Heating inside the screw shear will release some of the lower molecular gas, especially PVC, POM, PS and other chlorine containing benzene plastic raw materials, volatile gases are harmful to human body.
Q:What can soften a hardened plastic?
Thermoplastic structures are linear structures that soften or melt when heated and are plastically made into a definite shape and hardened after cooling. After heating to a certain extent, it softens again and hardens again after cooling. This process can be repeated many times. For example, most plastics, such as PE, PP, PVC, PPR and PS, belong to thermoplastic plastics. Thermoplastic molding process is relatively simple, can be continuous production, and has a high mechanical strength, so the development of very fast.
Q:How is the recycling of plastic bottles handled?
The properties of polyethylene vary depending on the molecular structure and density.Mainly used in the manufacture of films, containers, pipes, monofilament, wires, cables, daily necessities, etc., and can be used as television, radar and other high-frequency insulation materials.
Q:Electric kettle is plastic, okay?
Precautions for using an electric kettle1, before use, should check your power voltage and nameplate (at the bottom of the kettle) the target voltage is consistent.2, do not use when water is not added, prevent dry burning.3, ensure that the power supply base and connectors dry, beware of leakage.4, in the power on state, metal objects can not touch the contact in the power base.5, the water should be careful when boiling, in case the water vapor burns.6, in the area of hard water users should regularly for kettle, available vinegar or salt water immersion electrolysis (sodium hypochlorite).7, when the water is boiling, steam comes out very high temperature, should be avoided by hand or touching other parts of the body and a kettle cover and the kettle spout gap between the handle, to avoid burns.
Q:Mobile phone shell or other plastic products, the internal screw column thread is injection, or?. After injection processing?
The internal screw column of a mobile phone shell and other products has smaller diameter, and the screw column thread of the utility model is not molded out by injection, but is processed in the late stage.
