In recent years, smart dimming glass has been widely used in home partitions, hotel bathroom partitions, office partitions and other scenarios. The glass itself has all the characteristics of safety glass, but also has the control of glass transparent or not privacy protection function. EC dimming glass has a slow response speed, which may be as long as several minutes. PDLC has very limited thermal insulation effect. Increasing the thermal insulation effect can add a layer of low-E glass, while SPD and EC technologies have good thermal insulation effect.Due to the relatively high operating voltage, the application scenarios are relatively limited due to the consideration of security risks, and are relatively rare in China. PDLC has two basic states: transparent and atomized. Even if glass atomized, a lot of light will pass through, that is, transparent but opaque. PDLC can also create transformable transparent or atomized graphic effects on glass, with good design and expansion properties. EC and SPD can continuously adjust the rate of light passing between transparent and colored states, but cannot design graphic effects.
Water-based cold paste peritoneal glue technology (solid content 12%-40% adjustment)
Following the low cost and high quality---the new technology of anti-theft door styrofoam
First, the product application range: 
Beijing Huaxia Keyuan Technology Development Center (please visit: http://) The adhesive expert group has made a major breakthrough on the basis of the original water-based cold-adhesive peritoneal glue technology after more than one year of technical research, completely changing the tradition. The production process of peritoneal glue not only reduces the production cost and improves the quality of the products. The products produced by this technology are produced from the original one-ton reaction kettle (8 hours) to produce 1 ton of glue per day, and now it is changed to produce 3 tons of glue every day for 8 hours. Adjusting from 12% to 40%, the product is mainly suitable for biaxially oriented polypropylene film, polyester film and color printing paper. Applicable to the cover of hardcover books, product advertisements, brochures and other high-end prints and various paper and gold, silver cards, box bags and plastic composite . 
Second, features: 
1. Non-ethylene-vinyl acetate emulsion, good adhesion to film and ink. 
2, the composite light brightness is good, the pattern is realistic, never change color, no white cloud cloud point. 
3, the composite is loyal to the color, does not destroy the ink color. 
4, can be adapted to bronzing, gold, silver, composite product rolling line, ç ¸ bumps are not affected. 
5, green environmental protection products, non-toxic, non-polluting, non-combustible and non-explosive. 
6, no heating, the amount of glue per square meter is about 10 grams, the process adaptability is good, the standby time is long, anti-skinning time is long. 
7, freeze-thaw stability is good, winter use is not affected. 
8. This product is suitable for both old-fashioned laminating machine and new laminating machine. 
Third, the production conditions: 
The workshop is 50m2～80m2, one reactor (with heating device), workers: 2~5, general measuring instruments. The cost is about 1,200 yuan to 4,500 yuan per ton, and the market price is 4,500 yuan - 8500 yuan. 
Fourth, the basic parameters: Project indicator index pH value 6.5~7 Solid content 12~40 Viscosity 160～230 Storage period ≥6 months Exterior White lotion
Five, use: 
1. The glue is evenly coated on the surface of the peritoneum and directly attached to the paper. The amount of glue placed on the winding is determined according to the specific conditions of the paper and film. The pressure is not suitable for the glue to be pressed out. 
2. After the winding, place it for about 15 minutes and start cutting. 
3. After use, please clean the machine and tools with water. 
Sixth, technical service methods: 
1. Provide a full set of technical formulas, process materials, on-site training, and so far. 
2. The technology transfer training fee is 26,000 yuan, and the solvent-based laminating glue technology is given. 
3. At the same time, learn the two techniques of water-based laminating adhesive and dry laminating adhesive, which can be preferentially 15-20%.
Seven, special instructions:
1. Recently, some customers in Anhui, Jiangsu, Shandong and Hebei have received water-based peritoneal glue and oily peritoneal glue in Sichuan, all of which have technical problems and cannot be solved. Later, after I re-learned water-based peritoneal glue (oil-feeding peritoneal glue) Now, the production of 25-28% solid content of the cover powder is better than the original 38%. The receiving unit can go to the factory for field visits and study.
2. For manufacturers who are currently producing water-based peritoneal glue, a 10% discount can be given.
