Problems and precautions in the application of cigarette bag gravure water-based ink

With the continuous application of new technologies and the increasing awareness of environmental protection, benzene based gravure printing inks have gradually faded out of people's sight, replaced by ester soluble and alcohol soluble inks, especially water-based inks, which have been hyped by the industry in recent years for their superior environmental protection. Next, Xiaobian summarizes his understanding of aldehyde ketone resin as follows, hoping to promote its popularization and application.

The storage and transportation of water-based coatings do not contain flammable organic solvents, so it is relatively safe to store and transport. In case of pollution, a large amount of water can also be used for washing and dilution. However, the storage and transportation of water-based coatings have temperature requirements, and it is necessary to carry out insulation transportation and storage at minus 5 ℃, otherwise emulsion breaking and other ills will occur. Most of the functional surpassing solvent based coatings are organic products. Organic products will have a series of problems such as chain breaking and carbonization under high temperature conditions. At present, the high temperature resistance of organic product Z does not exceed 400 ℃.

The special high-temperature resistant coating with special inorganic resin in the water-based coating can withstand thousands of degrees of temperature. For example, ZS series high-temperature resistant water-based coating can also withstand high temperature for a long time while taking into account the corrosion and oxidation resistance of conventional coatings. Z high temperature can withstand 3000 ℃ high temperature, which is a height that solvent based coatings cannot achieve. Safety and environmental protection differences solvent based coatings have potential safety hazards of fire and explosion during production, transportation, storage and use, especially in confined space construction, which is prone to suffocation and explosion. At the same time, organic solvents will also cause certain harm to human body.

Z's famous case is toluene carcinogenesis, and now toluene is no longer allowed to be used. The VOC of solvent based coatings is high, and the conventional products are even as high as more than 400. Enterprises have great pressure on environmental protection and safety when producing and using solvent based coatings. Water based coatings are environmentally friendly and safe in production, transportation, storage and use (except for fake water-based coatings from some informal manufacturers), which has made great contributions to the corresponding national policies of energy conservation, emission reduction, safety and environmental protection.
