Antifogging paint is a very practical paint, it can prevent fog, block people's sight, the basic principle and definition of antifogging paint what, let us know about it. Antifogging coating is a kind of functional coating.It is based on the hydrophilic group or hydrophobic group as the main component of polymer materials, and other additives and organic solvents in proportion to prepare, with anti-fogging function of chemical products. Because solidify method is different, have heat solidify to prevent fog coating and UV(ultraviolet) light solidify to prevent fog coating ultraviolet solidify to prevent fog coating to have higher transmittance than heat solidify to prevent fog coating normally.Uv-curable antifogging coatings usually have higher light transmittance than heat-curable antifogging coatings.Because they have different antifogging mechanisms, they also have hydrophilic antifogging coating and hydrophobic antifogging coating hydrophobic antifogging coating is more widely used than hydrophobic antifogging coating. Whether it is heat curing anti-fogging coating or uv curing anti-fogging coating, there are only two types of anti-fogging mechanism: hydrophilic anti-fogging and hydrophobic anti-fogging. Hydrophilic antifogging and hydrophobic antifogging are two different processes of water molecules, so their antifogging mechanisms are completely different: hydrophilic antifogging coatings make surfaces hydrophilic and reused. Anti-fog coating hydrophilic groups of hydrophilic adsorption moisture factor, reduce the surface tension of water, reduce water molecules and the contact Angle between the surface and the water vapor is not on surfaces accumulate into small water droplets, will be wet, spread or forming a thin transparent film adsorption on the surface, no longer scattering incident light, does not interfere with the line of sight of people, so as to achieve the purpose to prevent mist.

Printing mucilage requirements The requirements of printing mucilage for manual plate printing Manual table printing is to press the screen on the fabric of the table for manual scraping, and the pressure extrusion on the scraper will print the glue through the mesh hole of the pattern part to the fabric. The shear stress of the binder is small, so thePrinting mucilageis required to have good rheological and mesh permeability, that is, the viscosity decreases when the scraper is scraped, and the mesh is transferred to the fabric, and permeated to the fabric interior; When the scratch printing stops, the shear stress disappears, and its viscosity can quickly return to the original level, to ensure that the pattern printed on the fabric is clear, so the printing paste used for manual platform printing should have a certain thickness, that is, a higher viscosity, but the rheology is better, the lag thixotropy is small. The requirements should be paid attention to during the scraping operation Drawing printing pulp is a kind ofPrinting mucilagepulp material, is a kind of milky thick pulp, mainly used for drawing printing process printing, its flow performance is very good, not plug net, quality is stable, the use of process is very simple. Printing pulp in scratch printing operation should pay attention to the method and requirements: mesh between 800-1200 mesh; Drawing printing powder to add 5%-10%, to stir to decompose completely; Before starting printing, the pulping glue should be filtered. If it is found to be thick in the production process, it is necessary to stop using it.Press, printing parts to be dry to press, in order to avoid color. If the flower appeared white edge, then it is necessary to pressure that overheating; Heat treatment after printing, bake for 3 minutes or press for 15-2 seconds between 150-170℃; When scraping printing, scraping 4 knives at a time.  Printing mucilage and substrate matching requirements Printing manufacturers in the process of printing production, often encounterPrinting mucilageand cloth adhesion problem.The main reasons for this situation are as follows: the surface of printed cloth (cut piece) is covered with water-repellent coating grease material and other substances, resulting in insufficient adhesion betweenPrinting mucilageand printed cloth; The adhesion ofPrinting mucilageitself is not enough, resulting in poor adhesion; Improper operation of printing process will also cause poor adhesion, such as insufficient printing strength, less pulp or no appropriate drying method,Printing mucilageis not completely solidified. Therefore, before printing factory production, it is necessary to choose good Printing mucilage and substrate matching, and make samples, and then production, to ensure the quality of production products.

Laminated oil magnetic cards, Identification Card and other cards used in water-based adhesive. The card is both a document and a form or carrier of the document's existence, although it has entered the 5G era,Many things exist in electronic form, such as electronic balance cards, electronic driver's licenses, electronic health care cards, etc.But the physical card such as id card bank card is also a must in daily life, you have encountered this kind of distress?It's the skin on the top of the card and if you open it up, if you peel it off over a long period of time the pattern inside can get worn down, and sometimes it can even affect the circuits or chips inside,If it is not torn, it will be ugly, so a good card will need to use a good card glue to do it will have a better experience.  Here is to introduce the operation process and use process of our card glue. Base material: card glue ,PVC film ,Identification Card Equipment:Card compound equipment, oven, wire rod operation process 1.Apply the card glue to PVC film with a wire rod 2.Put PVC film into 70 oven for 1-2 minutes, and then half dry 3.Put the card and the baked PVC film together into the card compounding equipment 4.Press and take out to test adhesion The above is all the operation process, our card glue produced by the product stability and high strength, welcome to understand the consultation.
