Surfactants play the role of wetting, dispersing, emulsifying and solutizing in pesticide processing, and have become one of the indispensable components of pesticide preparations, and are often called auxiliaries, emulsifiers, dispersants, auxiliary agents, etc., they can be a combination of a variety of surfactants.At present, pesticide formulations are developing in the direction of waterborne,...
The processing method of aluminum plating film is to vaporize metal aluminum through high temperature under high vacuum, making aluminum vapor deposit on the surface of plastic film, thus forming a composite flexible packaging material. In soft plastic packaging, aluminum plating film often used is basically divided into two categories, CPP aluminum plating and PET aluminum plating, but because al...
Water-based pressure-sensitive adhesive is a type of adhesive that uses water as a solvent and is pressure-sensitive, that is, it can adhere quickly to the surface when slight pressure is applied. Due to its environmental protection, non-toxic, cost-effective, adjustable viscosity and other advantages, it has gradually become the mainstream product in the pressure sensitive adhesive market. Accord...
The foam problem in water treatment has troubled many people, debuting the initial foam, surfactant foam, impact foam, peroxide foam, circulating water treatment with non-oxidizing fungicide generated foam, etc., so the use of defoamer in water treatment is more common, this article comprehensively introduces the principle, classification, selection and dosage of defoamer! Methods of foam eliminat...
Advantages and disadvantages of the same type of defoamer Organic defoamer such as mineral oils, amides, low alcohols, fatty acids, fatty acid esters and phosphate esters has been studied and applied earlier, belonging to the first generation of defoamer, which has the advantages of easy access to raw materials, high environmental performance and low production cost.The disadvantages are low defoa...
Water dispersion system is commonly used to analyze the relationship between surfactant structure and dispersion.As a hydrophobic solid particle, it can adsorb the hydrophobic group of the surfactant, and if it is an anionic surfactant, the outward-facing hydrophilic genes have the same charge and repel each other. Obviously, the adsorption efficiency of surfactants increases with the increase of ...
Defoamer is a substance with low surface tension and high surface activity, which can inhibit and eliminate foam in the liquid, that is to say, defoamer can reduce the surface tension of water, solution, suspension, etc., to prevent foam generation or eliminate the original foam.Long-term defoaming is also known as defoaming, and the length of the defoaming time is the main sign of the quality of ...
1.Familiar with the properties of adhesives For bonding, adhesive is the basis, the selection of adhesive, its performance is an important basis. Different types of adhesives, with different properties, determine their various uses, only familiar with the performance of adhesives, in order to handy selection. 2.Identify the nature of the adhesive There are many types of adhesive species with diffe...
Whether the water-based film adhesive meets the quality requirements of composite products, in addition to the quality of the glue itself, but also related to the paper, film, equipment accuracy, operating experience and other supporting factors in the film coating process, after long-term practice, we summarized the common problems in the application of water-based film adhesive, and put forward ...
As a kind of widely used adhesive, coated adhesive has a variety of processes. Here are some of the common processes used: 1. Hot melt coating: hot melt coating is to place a layer of film on the surface of the print, and then through hot pressing the film and the print together.In this process, the laminating glue is heated to turn it into a liquid, which then forms a uniform coating between the ...
1. The effect of membrane material There are dust adsorption, particle impurities, poor plasticization and other crystal points in the film. The moisture absorption on the film surface of the material and the precipitation of additives in the material will cause composite bubbles. The thickness of the film should be as uniform as possible, if the distribution is uneven, it is easy to cause the imb...
Water-based adhesives for printing are very common, which mainly include water-based pasting adhesive, laminating adhesive, water-based sealing adhesive and so on. Water-based laminating adhesive Water-based film adhesive has been widely used in recent years for its high brightness, low cost, easy operation and water-based environmental protection. Water-based film adhesive is mainly divided into ...
First, environmental performance VOC content Needless to say, water-based wood paint is perfect in this respect, water-based wood paint is based on water as a solvent with ultra-low VOC content, and will not produce pungent odor during construction. Nitrocellulose paint and polyester paint add organic solvents, and their products contain benzene, toluene, xylene and its derivatives, whic...
The difference between water-based paint and paint: Compared with paint, water-based paint, its wear resistance, and aging resistance have been significantly improved, compared with traditional paint, water-based paint is more affordable, more easily used by people, and less harmful. Water-based paint, water as diluent, with wear-resistant, aging resistance, easy to use and other characteristics, ...
There are four common waterborne polyurethane thickeners: ①Inorganic thickeners, such as flake silicates, fumed silica, etc.; ②Natural organic thickeners, such as cellulose ethers; ③Synthetic organic thickeners, such as polyacrylates, polyvinylpyrrolidone; ④associative thickener. This paper mainly introduces the associated emulsion thickener. Associative emulsion thickeners are non-ionic synthetic...
Organic pigment is the most basic material to provide color to the ink, but as the ink attached to the surface of the substrate, the color shown to the consumer often produces more or less deviations from the color of the pigment itself. The reason is that in the ink, the pigment particles do not exist alone, but are dispersed in the connecting material medium. Microcosmic, the best wetting disper...
