Newly bought plastic toys or plastic toys that have been used for some time will produce a lot of bacteria. At this time, it is necessary to clean it in time, otherwise it may have adverse effects on the body. So how to clean and disinfect plastic toys? Let’s take a look at the following: First, the boiling disinfection method Usually the traditional method of disinfection refers to the boiling method, and the method is also very simple. Cook a […]

Plastic toys are good friends of children, and choosing a good toy is very important. Many parents think that children’s toys don’t last long, so they like to go to the small commodity market to buy, which is cheap and has a lot of tricks. However, if you do not have the 3C logo, parents should never buy. Because this toy may be the murderer who harms the child. The choice of plastic toys depends on whether there is a […]

The name of white electric oil is n-heptane, which has high fat solubility and high volatility. It has strong decontamination ability in electroplating processing of plastic products, so it is often used as a cleaning agent in the industry. It is used in hardware, electronics and plastic plating. The use is particularly extensive. However, white oil is actually a very dangerous substance. Someone may have to ask? White oil is so dangerous, don’t you use it? Or what are the […]

The quality of toys in the children’s toy market can now be described as good or bad. There are many small toy manufacturers who do not hesitate to shoddy. Not only are they particularly harmful to children, but they are also subject to legal sanctions. What are the security risks of plastic toys? Here are some introductions: Plastic recycling enterprises use simple waste plastics from simple sources to be processed into “two materials”, which are supplied to toy factories as […]

Plastic products can be seen everywhere in our lives. Plastic products are also produced by factories. Enterprises will have many problems when processing plastic products. The shrinkage of plastic products is one of the common problems in processing. Let’s take a look at the reasons for the shrinkage marks in plastic processing. There may be one or more reasons for the formation of shrinkage marks in plastic products, including processing methods, component geometries, material selection, and mold design. The geometry […]

A common defect in the production of plastic products, the main reason is due to stress deformation. There are mainly residual stresses, external stresses, and stress deformations caused by the external environment. Residual stress is mainly caused by the following three conditions, namely, overfilling, demolding, and metal inserts. As a crack generated in the case of overfilling, the solution can be mainly achieved in the following aspects: 1. Since the pressure loss of the sprue is the smallest, if the […]

The production of plastic toys requires the consumption of petroleum resources, while petroleum resources are non-renewable resources. It is everyone’s responsibility to produce high-quality plastic products with limited resources. Sometimes, the surface of plastic injection molding will appear dull, or shiny, uneven color. Why? For this phenomenon, summarize the reasons and solutions. 1. The injection speed of the injection molding machine is too fast, and the material retention time is too long, which may cause the surface gloss of the […]

Polymers are composed of many small, simple structures with small bonds that are covalently bonded. There are many kinds of polymers. Generally, if they are classified according to changes in heat, they can be divided into two categories of plastic products. Let’s take a look at them in detail today. Let’s take a look. 1. Thermosetting plastics.. refers to the combination of molecular structure into a network form after heating. Once combined into a network polymer, it will not soften […]

Due to climate change and pollution, plastics manufacturers estimate the environmental cost of using plastics to be estimated at $75 billion. However, cost savings can be achieved by closed-loop recycling and the use of biodegradable polymers. If you expand these behaviors, you can create a net worth of $3.5 billion a year. Citing the example of Dell closed-loop recycling, using recycled plastics from its own products to create new computers, according to plastics manufacturers, if every plastics manufacturer can recycle […]

In the process of plastic melting and plasticizing, the mold of plastic products is prone to defects. The solution is to reduce the quenching stress after heat treatment to a very low level, because the quenching stress and the reticulated carbonized structure are under the action of grinding force. Extremely easy to crack the workpiece. Reasonable use of cooling lubricants, play the three major functions of cooling, washing, lubrication, keep cooling and lubrication clean, and thus control the grinding heat […]
