We all know that surface printing ink must emphasize their luster as the film can not be supplemented by light. However, polyamide resin has a problem with residual solvent. Because the plastic gravure printing process is mainly by hot air to dry, hot air to dry the ink surface, the drying mechanism is from the outside dry, from the outside in, gradually dry out. But since the outside dries first, the membrane forms first. The formation of this layer of film, although to avoid the next color group printing ink stick, but also prevent the inner layer of solvent emission. Therefore, the use of polyamide resin ink printing, in order to make the ink thoroughly dry, the hot air should be properly opened larger, the speed can not be too fast. To remove as much residual solvent as possible. Otherwise, we often meet this situation in our daily production. A roll of finished products printed down, packaged into the box, after a period of time to open, a pungent smell on the face, this is often recruited to customer complaints of residual odor problem. To solve this problem, we suggest that on the basis of not changing the ink, take the following measures: 1. Appropriately increase the drying temperature, slow down the speed, so that the solvent volatilization is sufficient; 2. Check the exhaust gas system of gravure printing machine, check the air inlet pressure and the air outlet pressure, refer to the data provided by the printing machine manufacturer, make the pressure difference as large as possible. Sometimes, the heat has been opened too much, but the smell is still there, at this time, it is necessary to check the wind pressure, if only the temperature and no qualified wind pressure, the solvent is still not very good volatile. Pay attention to check whether the air duct is smooth. In the days of low pressure, the exhaust system itself can not meet the process requirements, then we should check the rationality of the exhaust system. If you have any problems when you are producing ink, pls let us know. Then we will give you reply timely.

In July, Sunman company organized a long travel to Xinjiang province. Xinjiang is the province with the largest area, the largest number of bordering neighbors, and the longest land border area. Standing on the ancient Silk Road, Xinjiang is famous for being dominated by desert, mountains, stunning lakes, green grasslands, and its ethnic religion and colorful customs. Xinjiang Tourist Attractions: the Tianshan, Bayanbulak Swan Lake, Bayanbulak grasslands, Urumqi Mogui Cheng, Changji Cheshi old course, Narat grasslands, Sailimu Lake, Ili, Guozigou, Altai, etc. The sceneries at there are very beautiful: The company organizes such travel from time to time to enrich cultural life of employees, advocate healthy and up-to-date lifestyles of employees, enhance the team cohesion and centripetal force of all employees of the company.

Due to today's overall environmental protection and resource conservation, water-based inks have received widespread attention from inside and outside the industry due to their unique environmental performance, and have become the main direction of the current ink industry development. So, what is the advantages of water-based Inks? Waterborne ink features and advantages: 1. Water-based ink is a new environment-friendly printing ink with good adhesion, good softness, good elasticity, anti-adhesion, water resistance, good printing ability and high solid content. 2. Non-flammable, stable ink, non-corrosive printing substrate, prevent color change, strong water resistance and rapid drying. It can not only reduce the hidden danger caused by static electricity and flammable solvents, but also reduce the residual toxicity on the printing surface, and it is very convenient to clean the printing equipment, so it is especially used in food, beverage, medicine and other packaging industries. 3. Water-based ink solvent for water and a small amount of alcohol, significantly reduce VOC emissions, can prevent air pollution, does not affect human health, in direct contact with the human product, such as: T-shirt and other pure cotton, elastic cloth, insole printing industry also has a very wide range of uses, is the world recognized environmental protection materials, is currently all printing ink approved by the United States Food Association of ink. Fyi, our water-based acrylic resin is the mainly raw material to produce water based ink. If you need goods, pls contact with us.
