With the gradual improvement of national living standards, people on the printing and packaging of exquisite, green and other requirements are getting higher and higher, thus driving the printing and packaging industry to flourish, but also led to a large number of productions about adhesive which is used for printing. One of the water-based adhesive with its water-based environmental protect...
Textile dyeing and finishing auxiliaries according to the production process can be divided into two major categories of textile auxiliaries and printing auxiliaries. Dyeing and finishing auxiliaries in the dyeing and finishing industry is widely used, has penetrated into the printing and dyeing processing of all corners, its main uses are: lubrication, wetting, penetration, promote dyei...
The method to determine whether the quality of the seal printing tape is poor: Ordinary sealing tape glue is acrylic glue, also known as pressure-sensitive adhesive, the main component is tincture. Tincture is a kind of macromolecular active substance. The activity will be affected by the level of temperature. Tincture content of glue will directly affect the use of tape. Some individuals thi...
Factors affecting the curing speed are the main types of paint, coating thickness, curing methods, curing conditions, curing equipment and specific curing procedures. 1.The type of paint Under the same curing conditions, the type of paint is different, the curing speed is very different. Generally speaking, the volatile paint curing fast, oily paint curing is slow. Polymeric paint is very dif...
The Selection of good quality water-based adhesive not only help to improve the production efficiency, but also to protect the appearance of the product quality. Such as widely used in the field of self-adhesive water-based pressure-sensitive adhesive, such as water-based pressure-sensitive adhesive which is widely used in the field of stickers. This adhesive has many advantages, it is particularl...
Some of the traditional glue in the adhesion of a great advantage is good adhesion, and the efficiency is very low, the most important thing is relatively low cost, most are someorganic materials. Relatively speaking,the biggest advantage of water-based adhesive is green, the traditional glue is inorganic materials, so it is not very environmentally friendly, pollution is relatively large, water-b...
Future development of waterborne paint: In foreign countries, the application of waterborne paint is very wide, especially in the application of home decoration is very mature. In domestic already many enterprises are used at inside ark besmear, cane implement besmear is installed wait With the development of waterborne paint technology, waterborne paint will become a very important paint in furni...
Plastics are classified into two types: thermosetting and thermoplastic.Among them, thermosetting plastics have high cross-linking density, good solvent resistance and heat resistance, relatively high surface polarity, and wide range of coatings available.For example, unsaturated polyester is called polyester fiberglass. The texture is hard and polar, and there are many coatings that can be used. ...
Waterborne paint testing and standards:hardness Hardness is one of the most important physical properties of a coating. Coating hardness reflects the coating's ability to resist constant dents, scratches, scribes, and penetrations caused by a hard object. Testing the hardness of materials with different methods will give different results because the testing methods are for different amounts of ma...
Current problems with waterborne polyurethane adhesives: (1) Low solid content: At present, the solid content of water-based polyurethane (WPU) can reach 45%. Fewer systems lead to higher drying and transportation costs. Increasing the solid content leads to an increase in the viscosity of the system, which makes emulsification and dispersion difficult. Reduced emulsion stability. (2) Slow drying ...
Environmentally friendly water-based polyurethane waterproof coating is two-component,The component A is an isocyanate-terminated prepolymer obtained by polycondensation of polyether and isocyanate, and the component B is a colored liquid composed of a plasticizer, a curing agent, a thickener, a coagulant, and a filler.After use, the two components of methyl and ethyl are evenly mixed according to...
In polyurethane waterproof coating construction often encounter some problems, so in the process of waterproof construction encountered different problems how to solve it?sinograce waterproof with you to learn the following, polyurethane waterproof coating construction common problems and solutions. 1. viscosity (1) coating itself viscosity is very large, construction effort. (2) if the client app...
Composition of water bases adhesive 1.adhesive: also known as adhesive agent, after the surface treatment of two or more adhesive materials firmly connected together, and has a certain mechanical strength of chemical properties, such as epoxy resin phosphate copper oxide white latex. 2.Solid material (base material): determines the main physical, chemical and mechanical properties of rubber joints...
1.Principles of adhesive selection Consider the type, nature and hardness of the bonding material Consider the shape, structure and process conditions of the bonding material Consider the load and form (tensile force, shear force, peel force, etc.) borne by the bonding part; consider the special requirements of materials such as high temperature and low temperature resistance. 2.Properties of bond...
