The main body of metal printing is tinplate printing. However, due to low tin production and high prices, chrome-plated or tin-plated thin steel plates have been used in recent years. Decorative building materials are mainly galvanized iron plates. Aluminum materials are printed as thin plates, foils, stamping cans, and drawing cups. Compared with other printing materials, metal is characterized by its smooth surface, hard texture, and wood-absorbing ink. Therefore, the printing ink must be a fast-drying or UV-curing photosensitive ink; at the same time, since the printed metal substrate needs to pass through Mechanical processing, but also required to dry the coating and ink film is strong enough; if you want to make food cans, you must pay particular attention to the high temperature and other factors in the sterilization. Therefore, the printing ink should have the same characteristics as ordinary offset printing; the ink film of the printing ink should not be discolored, discolored or yellowed after being heated and dried; it should have good solvent resistance and prevent bleeding when glazing; printed iron products Most of them need to be processed through stamping, punching, bending, and sealing. The ink film should have good adhesion, flexibility, surface hardness, and impact strength. As a daily product, printing ink should not be affected by light or climate change. And fading and aging and so on. Since the metal material is not hygroscopic, the paint, the printing, and the glazing are all in a wet state, and therefore must be dried; and wet and wet multicolor printing cannot be performed, and only two-color printing can be performed on a screen with less overlap. If UV drying inks are used, multi-color printing can be performed using a four-color tin printing press. In iron offset printing, hard rubber erasers and hard liners should be used, otherwise the outlets will be poorly reproduced. Ground screw anchor are generally cut, deformed, welded, pickled, hot-dipped, and other processes to produce qualified piles. Among them, pickling and hot-dip galvanizing are important treatment processes that directly affect the service life of the screw piles.

The processing level of the pile directly determines the service life of the metal pile, such as the quality of the selected welded pipe, the quality level of welding, whether there are blisters, virtual welding, and the width of the welding. These all affect the future service life of the pile and the quality of subsequent processing. Pickling is an important foundation process, and the quality of hot-dip coating, such as the time of hot-dip coating, and the appearance of surface treatment, all affect the quality of pile treatment. Under normal circumstances, spiral piles can be used for 40-80 years. The environment and application method of the application process also affect the service life of the pile. For example, the acidity of the soil, whether the operation process is proper, or improper use will cause damage to the surface of the metal pile and damage the metal protective layer. Corrosion of metal piles is accelerated, reducing service life.
How to use spiral piles in messy terrain?
For the terrain, there should be many different terrains. How to deal with the messy terrain?
If it is a severe situation that the drilling tool cannot be lifted and released, and the impactor does not sound, now as long as the rated torque is added or auxiliary tools are used to assist in the improvement, the drilling tool is reversed, and then it is required to increase the drilling tool while air is being supplied. , Until the problem processing stops. During heavy drilling, first apply a little pressure, and then gradually increase the propulsion force until the normal working pressure is reached.
