There are many plastic products and many plastic printing products in our life. Different types of plastics have different printing characteristics. In plastic printing, what are the characteristics of different plastic printing?
There are many kinds of plastic printing process, screen printing is the main one, it is the secondary processing of plastic in the processing process. Plastic secondary processing is generally to finish the surface of plastic, change its color, appearance, or make up for the wear resistance of plastic. Therefore, for plastic printing, printing technology is very important. Here are the characteristics of different plastic products after plastic printing
1. PVC plastic printing
PVC has been produced for nearly one hundred years. PVC plastic printing products have bright color, good tensile strength, acid and alkali resistance, good toughness and low price. But in the production process, many harmful auxiliary ingredients are added, so it is often toxic, not easy to degrade, not easy to package food, so the current PVC plastic products are not very popular in the market. But many plastic cloth and leatheroid are PVC products.
2. ABS plastic printing
ABS is a copolymer of acrylonitrile, butadiene and styrene. As an engineering plastic, ABS is widely used in computer, computer and other fields. Therefore, ABS plastic printing has been widely used. Because ABS is composed of three compounds, ABS has the characteristics of these three compounds: acrylonitrile makes ABS corrosion-resistant, high surface hardness; butadiene makes ABSplastic itself has a wide range of colors, so after plastic printing, it has bright colors, good glossiness and good waterproof performance. At the same time, ABS plastics have good mechanical properties, tensile and impact resistance. Even above - 40 ℃, ABS plastics still have good tensile strength and stable chemical properties. Suitable for plastic printing process, easy to process, easy to form, good printing effect.
3. PE (polyethylene) plastic printing
Polyethylene is a kind of widely used plastic products. The molecular structure of polyethylene is complex, which determines that the higher its density is, the more complex it is for plastic printing. Only at high temperature can polyethylene be slightly soluble in some special solvents, such as toluene and amyl acetate. Therefore, in the process of plastic printing, it is necessary to print under high temperature environment, soak the plastic with heating solvent, and increase the ink adhesion by destroying the surface crystallization.
What are the characteristics of different plastics in plastic printing? The above three kinds of plastic printing have a high proportion of plastic varieties. For these different plastics, the characteristics of plastic printing are different, so it is necessary to carefully select and choose the right type of plastic printing.
