Development and application of dry ice blasting in production industry
The mold plays a vital role in industrial production, because the quality of the mold directly affects the quality of the workpiece. The mold is often used in high temperature and high humidity environment. After long-term use, there are many residues accumulated in the internal carved lines, which will affect the precision of the mold and the shape of the final product, leading to the increase of defective produ

Dry ice, which is solid carbon dioxide, is known for a variety of uses, including preservation and refrigeration. Generally dry ice has two states, one is small pellets, used as a cleaning agent for industry; another is dry ice blocks, used as a refrigerant for food preservation.

The cooling capacity of dry ice is more than 3 times that of water ice. After absorbing heat, it sublimates into carbon dioxide gas，no residual, no toxicity, no odor, and has the effect of steriliz

There are car repair and maintenance knowledge you don`t know, and the true stories behind those illusions. If you want to become a real car expert, here will be one of the better ways for you to add knowledge. Regarding the known, unknown, curious, and ignorant of the car, you can find the answer here. For both you and me, this may be a new beginning!

Carbon deposition is an unavoidable problem for almost every car. No matter whether it is Japanese, American, European, high-end or lo

The ink on the printing machine is not easy to clean, but the cleaning degree of the printing machine directly determines the quality of the product, especially the pure white and clean paper is easily contaminated by oil. Choosing a suitable cleaning method is particularly important for the printing industry. Whether the most admired dry ice cleaning method can completely solve the problems of the printing industry is of concern to people in the printing industry.

Dry ice cleaning is used to clean oil stains, gas residues, plastic residues, inorganic salts, hand sweat, dust and other dirt on the surface of mold steel, beryllium copper mold steel and rubber molds. Dry ice cleaners are often used for cleaning injection molds, die-casting molds, and rubber molds. Dry ice cleaners are often divided into general-purpose and particulate. Large-scale enterprises use general-purpose dry ice cleaners to clean the equipment. Its characteristics are that it has a

Dry ice is pure CO2, which is made by decompressing liquid CO2 to produce CO2 snow. The snow is then compacted and extruded through a die plate to form solid CO2 pellets. Dry ice is unstable above minus 78.6°C, but it will not melt into CO2 liquid, but directly sublimate into CO2 gas. It is this sublimation process that produces a cleaning effect when dry ice is used as a blasting medium. During the spraying process, compressed air is used to accelerate the particles to a speed of 200-300

Precautions for the operation of dry ice cleaning printers. In the printing process of the printing press, especially the monochrome offset press, the trademarks, packaging and decoration often need to wash the ink and change the color, clean the entire inking system of the offset press, and then replace it. New ink. The ink wiper of the ink washing device is composed of a rubber knife, an ink receiving tank, and a tightening and loosening adjustment screw.

With the development of social networks, communication has brought us a lot of convenience. According to incomplete statistics, there are almost two laptops in China. It is conceivable that the after-sales market of laptops is huge, coupled with the rapid development of the network, the probability of repair is also relatively high. High, but it also brings trouble to the manufacturer when the notebook is repaired.

In order to ensure high-quality injection molding, how to thoroughly clean the complex cavity and vent holes of the mold? This is a common problem faced by plastic parts manufacturers!

In the process of injection molding, demolding or labeling, the residue inside the mold will cause the increase of defective products and damage the mold!

SO! Keep the mold clean and clean the mold thoroughly in time! Is the key to improve product quality and yield!

To store dry ice, you need to use a special storage box (dry ice incubator), but there will still be losses. A good storage box (dry ice incubator) can reduce the loss to 6‰, and the price will be relatively high. If there is no special box, ordinary foam boxes can be used for storage. In addition, try not to cut a whole piece of dry ice into small pieces or granules. Cut into small pieces of dry ice will sublimate more easily than a whole piece of dry ice. Do not put dry ice directly
