The current discussions around the global climate, petroleum energy and pollution issues have also caused manufacturers to be extremely sensitive and concerned about environmental issues in the printing industry. Therefore, the continuous maintenance of the ecological environment of production is a strategic element for the success of enterprises-ecological elements not only affect the production of printing press assembly, but also determine the production of printed products.
Reduce paper consumption
Papermaking requires a lot of energy, so paper is regarded as one of the components of the entire printing environment, and its manufacturing is related to most environmental impacts. Printing plants reduce waste paper is the most important contribution to environmental protection. The lower waste paper rate protects natural resources, while also reducing printing production costs.
Save the production process
Using simple techniques can save the production process. Various quick change options, such as improved sheet control and color management, are examples of waste paper reduction. According to the manufacturer, the pre-adjustment of fast-changing ink fountain slides (equivalent to ink fountain keys) is designed by itself and takes into account actual experience values. Therefore, the preset value of the required ink density can be quickly reached. The inking and landing sequence of the inking roller of the fast-changing color inking device avoids the ink color fluctuation of too dark and too light when printing is restarted and then restarted.
The quick air exchange technology can store the air volume adjustment, and the quick start can make the printing machine start at the production speed. ColorPilot (ink adjustment) technology is used to quickly adjust the ink color. For example, the Manroland online inspection device can identify waste pages early in the printing process and automatically reject the waste pages through the online sorter.
Effective temperature control
Modern fountain cooler, ink roller thermostat, air supply and drying system ensure a smooth printing process and increased productivity. The temperature and air humidity should always be kept within small tolerances in the printing shop. However, the residual heat generated by the air-cooled machine components will heat up the printing shop. An increase in the temperature of the printing environment is bound to use air conditioning, which in turn leads to increased production costs.
Selecting a mixture of water and ethylene glycol to dissipate heat from machine components is an ecologically meaningful measure. Due to the higher heat capacity and higher density of water and air compared to air, the pipe system using smaller diameter pipes can remove 50% of the machine's residual heat from the printing workshop.
The circulating water cooler installed outside the printing workshop is used as a heat exchanger, and the residual heat is discharged into the outdoor air through the fan. When the air humidity is higher than 40%, the water atomized in the cooling system can be evaporated by adiabatic cooling (that is, without heat energy exchange). In addition, you can also choose to use the waste heat to heat buildings and prepare hot water.
Reduce alcohol consumption
Another challenge for offset printing is to reduce the alcohol content in the fountain solution without reducing the printing quality. Isopropyl alcohol (IPA) belongs to VOC (volatile organic compound) due to its low boiling point. Many printer manufacturers currently strive to reduce or eliminate isopropyl alcohol. Manroland also provides certified products for isopropyl alcohol-free and isopropyl alcohol-free printing. Blankets, cleaning agents and fountain solutions, varnishes and inks, as well as ink rollers, printing plates and lubricants are all certified products.
Food packaging ecology
Nowadays, the food industry requires safe packaging. During the entire shelf life of the food, it will not damage the food, nor will it change the food, nor will it respond to environmental impacts. The packaging used for sensitive items must be made of mutually compatible raw materials, which not only fulfills the obligations stipulated by law, but also meets the requirements of customers. In addition, we must pay attention to the conditions of the production process and the special hygienic requirements of chemical and physical applications.
Modern people are paying more and more attention to health management, and hyperbaric oxygen chambers have become an important way to achieve health preservation. DOING hyperbaric oxygen chambers are widely used in various scenarios, including office workers, insomnia patients, beauty enthusiasts, and sub healthy individuals. In the future, the expansion of the market will broaden the application prospects of hyperbaric oxygen chambers.
DOING soft Hyperbaric Oxygen Chamber provides an environment above one atmosphere, allowing people to breathe high concentrations of oxygen inside the chamber. People absorb higher and purer concentrations of oxygen, thereby achieving an increase in blood oxygen concentration and improving hypoxia conditions.
DOING hyperbaric oxygen chamber adopts high-efficiency molecular sieve oxygen production technology, which is one of the most advanced, mature, and stable oxygen supply technologies in the world. Oxygen is produced through molecular sieve pressure swing adsorption.
The design of the two transparent observation windows in DOING hyperbaric oxygen chamber ensures that personnel outside the cabin can timely understand the situation inside and have a grasp of the situation inside. In addition, the transparent observation windows also provide sufficient lighting, giving users inside the cabin a sense of safety.
The automatic pressure reducing valve of DOING high-pressure oxygen chamber can automatically adjust the pressure in a high-pressure environment, keeping the pressure inside the chamber within the set threshold. DOING high-pressure oxygen chamber is also equipped with a manual pressure reducing valve. In case of emergency, users can open the manual pressure reducing valve to manually reduce pressure.
