Common problems with water-based paint: the coating contains bubbles and degassing Phenomenon: During the production of waterborne coating, it is found that the coating contains bubbles after thickening.The bubble volume is big bubble, the volume is small bubble, This kind of phenomenon often happens in paint of equal thickness thick pulp of elastic drawing. Bubble may cause pinhole or prickly hea...
The internal structure of waterborne acrylic emulsion particles will affect several aspects of waterborne paint formulations.According to the order in which the effects are affected, the phase structure will first affect the selection and addition of the filming aid.Different phases have different hydrophilic/lipophilic characteristics, and the oleophilic properties of various coalescents are diff...
With the development of The Times, many products in the production of nano coating, the coating can be very good protection from water and air substances invasion, the use of nano coating can obtain what characteristics, let us know about it. 1.Features The hardness of the coating is extremely high, which is more than 3 times that of tool and die steel, even more than 4000HV(ceramic characteristic...
What is nano coating? What are the advantages? Nano paint is a new high-tech coating, is the nano raw materials and coating material, in addition to add silicon oxide single slurry nano technology emulsion nano technology pesticides fungicide and other modifiers.The metope paint with relative tradition not only lacquer face is meticulous and extraordinary, and price also is cost-effective.The meto...
The bonding effect can be achieved by applying pressure for a short time (non-aqueous solvent heating) It overcomes the solvent volatilization and drying time needed during the operation of structural adhesive, and can improve the working environment After stripping, it can be corrected without contamination and can be reused for many times Easy to operate, can greatly improve the production effic...
In the process of coating manufacturing, it is necessary to belong to the hydrophilic polar material Yan, fillers dispersed to belong to the hydrophobic non-polar material organic base material.In order to increase the affinity between inorganic matter and organic polymer, it is generally necessary to use coupling agent or other surfactants to treat the surface of inorganic matter, so that it chan...
Sixteen common types of self-adhesive labels This paper introduces sixteen types of self-adhesive labels commonly seen in daily life. The specific types of self-adhesive labels are as follows: 1. Press smooth writing paper and offset paper labels Multi-purpose label paper for information labels, bar code printing labels, especially suitable for high speed laser printing, also suitable fo...
Classification and characteristics of screen-printable pressure sensitive adhesives I.Characteristics and performance requirements of screen printing process Screen printing is through a certain pressure to make the printing base material through the holes of the plate to the substrate, the formation of an image or text. In order to achieve good printing adaptability, the physical properties of sc...
Waterborne polyurethane: A new type of polyurethane system using water instead of organic solvent as dispersion medium, also known as water dispersed polyurethane, water polyurethane or water based polyurethane. Oily polyurethane: polyurethane system with organic solvent as dispersion medium, polyurethane system with thermoplastic linear structure. Distinguish by appearance Waterborne polyurethane...
Preparation method of waterborne acrylic emulsion 1.The preparation of water-based acrylic emulsion: the raw materials including acrylic hard monomer, acrylic soft monomer and acrylic functional monomer all acrylic monomer, emulsifier, water added to the pre-emulsifying kettle, emulsifying 30 ~ 40min.A non-stratified emulsion is obtained. Then the remaining water, remaining emulsifier and buffer a...
Acrylic resin is made of acrylic ester and methacrylate and other alene monomers copolymerization resin, through the selection of different resin structure, different formula, production process and solvent composition, can be synthesized different types, different performance and different application of acrylic resin, Acrylic resin can be divided into thermoplastic acrylic resin and thermosettin...
The addition of wetting dispersant has obvious effect on the foam of some water-based ink.For example, polyacrylic acid wetting dispersants foam more than other types of wetting dispersants.Generally speaking, wetting dispersant foam with low dispersion capacity is also less. If diisobutyl sulfonate is based on disate, there is little foam at its content of 0.1-0.25%. The use of thickeners will ma...
Water - based ink is also known as water - based (oil) ink, referred to as ink.Water-based ink is made of water-soluble or water-dispersed polymer resin, colorant, surfactant and other related additives through chemical process and physical processing. Water - based ink containing a small amount of alcohol water as solvent, ink stability.Therefore, it is especially suitable for food, medicine and ...
1.Water as a dispersion medium, do not use organic solvents, non-toxic or flammable danger, is environmentally friendly products; 2.Acrylic monomers have many types, containing ester groups, carboxyl groups, hydroxyl groups and other functional groups have strong polarity, it is easy to emulsion copolymerization with other monomers such as vinyl acetate, styrene, vinyl chloride, etc., to make emul...
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,...
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 ...
