The polymer in dry powder state is stable when the temperature is lower than 30 ℃. If the temperature is higher than this, the powder is easy to agglomerate, but this phenomenon does not affect the quality of the material, and the lump is easy to crush. The polymer in dry powder state is stable within 3 years when the temperature is lower than 30 ℃ and stored in a sealed container.
The international standard system needs to be optimized
The Chinese Pharmacopoeia is a legal technical standard that should be followed in the research, development and production of pharmaceutical excipients in China, and an important technical standard for the standardization and standardized development of pharmaceutical excipients industry in China. At present, the number of pharmaceutical excipients in use in China is more than 540, and the excipient standards included in the Pharmacopoeia have increased from 132 in 2010 to 270 in 2015. The number of varieties of medicinal excipients being used in the United States and Europe is about 1500 and 3000, respectively, and the standards of medicinal excipients included are about 750 and 1500, respectively, far away from China. In addition, many new pharmaceutical excipients have been widely used abroad, but there is no registration in China. Therefore, in terms of the number of varieties and specifications, China's pharmaceutical excipient standards have a great space for expansion.
Spring is the peak season for decoration, but the odor in the decorated room is a headache. How can you quickly eliminate the odor? In fact, you don't have to buy deodorant products. Some of the things you can easily get in your daily life can also remove the odor of decoration, and save money and protect the environment.
Two pots of salt water can be put indoors, and the smell of paint will soon disappear. If the smell of paint emanates from wooden furniture, you can scrub it with tea several times, and the smell of paint will disappear faster. To quickly remove the residual paint smell, the cotton ball can be soaked with citric acid and hung indoors and in wooden furniture. Fill the container with cold water, add some vinegar and put it in the ventilated room, and open the furniture door. In this way, the water can be evaporated properly to protect the wall top coating surface, and the residual odor can be absorbed and eliminated. The way to be economical and beautify your home is, of course, to put appropriate flowers and plants at home. The plants that can be absorbed are cactus, fulang flower (also known as gerbera), reed, evergreen, iron tree, chrysanthemum, etc.
When it comes to the "face project" of home decoration, I believe many friends have heard about it, but how much do you know about paint? How can we have an ideal healthy and environmentally friendly home? Xiao Bian brings some basic knowledge of paint today to make you realize your ideal home!
① What is the difference between paint and paint?
Answer: In our country, it is generally believed that the paint is water-based and low-grade. The paint is. In fact, this is a wrong concept. Paint includes paint, which can be divided into water-based paint and solvent (oil-based) paint. With the development of petrochemical industry, chemical products are emerging one after another. Most of the current coatings have broken away from the tradition of using oil to produce coatings. More and more coating products have better performance through chemical synthesis and are used more and more widely.
② What is primer?
Answer: The general function of the primer is to promote the adhesion of the finish paint and prevent the paint from penetrating into the substrate too much to affect the adhesion.
③ What is midcoat?
Answer: It is a layer of paint between the primer and the top coat. Its main function is to improve the adhesion between the top coat and the primer, and help to improve the hiding power and the degree of the entire coating. Some varieties can also play or provide the effect of surface three-dimensional graphics, such as relief paint.
④ What is a topcoat?
Answer: It is a coating in painting, which has decorative and protective functions, such as color texture, and also needs to be resistant to harsh environments.
⑤ What is the hardness of paint?
Answer: Hardness refers to the resistance of paint film to foreign objects invading its surface. The hardness of paint film is an important performance of its mechanical strength. Generally speaking, the hardness of the paint film is related to the composition and drying degree of the paint. For example, the more dry the paint film is, the higher the hardness is.
⑥ What is paint film?
Answer: The paint film is a kind of physical property, that is, the ability of the paint film surface to reflect the light on it. The more light reflected, the higher it will be. Paint film is an important indicator for decorative coatings.
⑦ What is the drying time of paint?
Answer: The physicochemical process of coating from fluid layer to solid film is called film drying. The time of drying process is called drying time. The drying process of film can be divided into surface drying and actual drying.
Easy construction of water-based furniture paint:
With tap water as the solvent, the source is convenient and local materials can be obtained at low cost. It eliminates the danger of fire during construction, improves the working environment, and has significant effect on reducing pollution and saving resources.
