Color paste, also known as pigment paste, is an important form of dye application, which is widely used in textile, ink, paint and other industries. In the classification of pastes, low-halogen pastes and ordinary pastes are two common types. They have certain differences in composition, performance and use, and the differences between the two types of pastes will be discussed in detail below. Fir...
1.There are many formulations of coated glue, and different formulations need to be determined according to the specific use. It generally includes basic glue, thickener, curing agent, auxiliaries and other ingredients. 2.Basic glue is the most important component of laminating glue, it can be selected according to different use requirements of different types, such as water-based, oily, dilu...
The performance requirements of water-based varnish for printing paper glazing are as follows: 1.The film has good environmental resistance. Some of the printed matter after glazing is used to make all kinds of packaging cartons, in order to be able to play a good protective effect on the packaged products, the environmental resistance of the glazing film layer must be better. For example, the pac...
The transparency of composite film is very high, but in the composite processing of plastic film, the composite film often has problems such as insufficient transparency. So, what is the reason for affecting the transparency of the composite film? This article analyzes one by one for reference. Improper selection of adhesives: Such as the color of the adhesive itself is dark or the fluid...
Ink scraping is not clean troubled many manufacturers, there are ten reasons for scraping is not clean, save it for use! 1.Ink viscosity is too high When the viscosity of the ink increases, the surface tension also increases correspondingly, and the force between them also increases, so that the scraper will increase the impact force of the ink on the scraper in the contact process with the ink, d...
First, material selection and preparation To make the resin crack effect, you first need to prepare the resin and pigment. Resin selection of high transparency, high hardness, wear resistance products, pigments can choose mineral pigments or metal pigments, you can also add a small amount of color pigments to prepare a rich color. Second, color mixing Mix the paint into the resin one by one and st...
Different processing methods will cause different fault manifestations, the following we mainly analyze the causes of paper thermit sealing delamination phenomenon under the gravure and solvent-free composite processing methods. The YBB paper aluminum-plastic composite film standard does not specify the composite strength index of the paper aluminum layer in the paper aluminum-plastic composite fi...
Water-based ink is referred to as ink, and flexible water-based ink is also known as liquid ink, which is mainly made of water-soluble resins, organic pigments, solvents and related additives by composite grinding processing. Water-based ink is especially suitable for tobacco, wine, food, beverages, medicines, children's toys and other packaging and printing products with strict sanitary condition...

Classification of surfactant applications in coatings: According to the role of the classification, the coating industry used surfactants can be divided into the following categories: emulsifier, pigment surface treatment agent, pigment wetting dispersant, defoamer, levelling agent, anti-mold, fungicide, antistatic agent, brightening agent, slippery agent and so on. Application of surfac...
Insufficient or uneven amount of glue due to insufficient amount of glue produced by the white spot can be observed in the composite machine. In the dry composite process, the coated adhesive must be able to fill the bumps and bumps on the surface of the ink and film to avoid appearance defects such as obvious white spots. When the water-based adhesive dry composite is used to produce lightweight ...
