What is the substance in the form of true solution in emulsion?

Solid content Solid content is the remaining percentage of emulsion or coating after drying under specified conditions, which is actually called nonvolatile content. The solid content is not only film-forming substances, but also emulsions such as fillers and additives. There is no clear definition of high solid emulsion. It is generally considered to be a high-solid emulsion with a solid content of more than 60%. Compared with the emulsion whose solid content is less than 50%, it has the advantages of high production efficiency, low transportation cost, fast drying and low energy consumption, and has become the research object of many researchers. Ai Zhaoquan and others have developed a kind of water-emulsion plastic-wood composite adhesive with high solid content, which can also be used for paper-plastic composite. TDI reacted with hydroxypropyl acrylate to obtain crosslinked prepolymer, and then it was prepared by emulsion polymerization with butyl acrylate, styrene and acrylonitrile. Its solid content is 60% 1%. The solid content of emulsion paper-plastic composite developed by Xu Zushun et al. [12] reached 62% 1%. Chinese name of peracetic acid: peracetic acid English name: peracetic acid Chinese name 2: peracetic acid English name 2: peracetic acid CASNo. : 79-2 1-0 molecular formula: C2H4O3 molecular weight: 76.05 physical and chemical characteristics main ingredients: content: 35% (by weight) and 18 ~ 23%. Colorless liquid with strong pungent smell. Melting point (℃): 0. 1 boiling point (℃): 105 Relative density (water =1):1.15 (20℃) Saturated vapor pressure (kPa): 2.67 (20. Health hazard: This product has strong irritation to eyes, skin, mucous membrane and upper respiratory tract. Inhalation can cause inflammation, edema and spasm of larynx and bronchus, chemical pneumonia and pulmonary edema. Contact may cause burning sensation, cough, wheezing, laryngitis, shortness of breath, headache, nausea and vomiting. Explosion hazard: This product is flammable, explosive, corrosive and irritating, which can cause burns to human body. Hazard characteristics: flammable, it will decompose violently when heated to 100℃, and it can be detonated in case of fire, heat or impact. Contact with reducing agent, combustion improver, organic matter, combustible, etc. will produce violent reaction, which is in danger of combustion and explosion. It is very corrosive. Peroxyacetic acid alias: Peroxyacetic acid, Peroxyacetic acid and PAA are broad-spectrum, quick-acting and efficient disinfectants. This product is a strong oxidant, which can quickly kill all microorganisms, viruses, bacteria, fungi and spores, and can be widely used for disinfection of various instruments and environments. Contact with 0.2% solution for 10 minute can basically achieve the purpose of sterilization. Used for air and environmental disinfection and preventive disinfection. Dosage and usage 1 Wash your hands and soak them in 0.2% ~ 0.5% solution for 2 minutes. 2 Plastic and glass products are soaked in 0.2% solution for 2 hours. 3 floors, furniture, etc. Spray with 0.5% solution. Note: 1 "stock solution" is highly irritating and corrosive, and cannot be directly touched by hands. It is corrosive to metals and cannot be used for disinfection of metal instruments. 3 "Stock solution" can be decomposed when stored, and the expiration date should be indicated. It should be stored in a cool, dark plastic bucket, away from olefinic substances.
