(1) Development and utilization of engineering plastics
At present, there are more than 10 major engineering plastic products, among which polyamine, polyoxymethylene, polyphosphate, modified polybenzoic acid and thermoplastic polyester are known as the five major engineering plastics. Their output is relatively large. The price is generally The traditional general plastic is 2-6 times. The price of special engineering plastics such as polysulfuric acid is 5-10 times that of general plastic. Replacing the three traditional basic materials of steel, wood and cement with plastic can save a lot of energy, manpower and material resources.
(2) Development and utilization of synthetic rubber
Due to the abundant raw materials for the production of synthetic rubber, and its good performance can meet certain special requirements put forward by the development of contemporary science and technology, so synthetic rubber has been very rich in varieties for decades, it can be generally divided into general synthetic rubber and There are two types of special synthetic rubber. The properties of general-purpose synthetic rubber are similar to those of natural rubber, and they are used to manufacture general rubber products, such as various tires, transmission belts, hoses and other industrial supplies and raincoats, rubber shoes and other daily necessities. Special synthetic rubber has the advantages of high temperature resistance, low temperature resistance, acid and alkali resistance, etc. It is mostly used in special environments and high-tech fields, such as aviation, aerospace, military, etc.
(3) Development and utilization of synthetic fibers
There are dozens of synthetic fiber varieties, but the most common are the six major types: polyamide fiber (trade name nylon), polyamine fiber (trade name polyester), polyethylene fiber (trade name acrylic), polypropylene fiber ( Trade name polypropylene), polyvinyl acid fiber (trade name vinylon), polyvinyl chloride fiber (trade name spandex).
Polymer synthetic materials have the characteristics of small quality and good insulation performance, so they have developed rapidly, but they all have inherent deficiencies, that is, they are sensitive to oxygen, heat and light to varying degrees. However, with the rapid development of high technology, the army of polymer synthetic materials will certainly play a pivotal role in economic life.
4. Ceramic materials
Fine ceramics have risen among the ceramic materials. It is unique in the world of new materials with high temperature resistance, super strength, multi-function and other excellent properties. Fine ceramics refer to high-performance ceramics sintered with refined high-purity artificially synthesized inorganic compounds as raw materials, which are sintered using a precision control process, so they are also called advanced ceramics or new ceramics. There are many types of fine ceramics, which can be roughly divided into three categories.
(1) Structural ceramics.
This ceramic is mainly used for making structural parts. Some seals, bearings, knives, ball valves, cylinder liners, etc. in the machinery industry are parts that are frequently subject to friction and are easy to wear. They are sometimes made of metals and alloys and will not be damaged after long use. Advanced structural ceramic parts can Withstand this "tribulation".
(2) Electronic ceramics
Refers to the functional ceramics used to produce electronic components and structural components of electronic systems. In addition to their high hardness and other mechanical properties, these ceramics can be "indifferent" to changes in the surrounding environment, that is, they have excellent stability, which is an important performance for electronic components. In addition, they can withstand high temperatures.
(3) Bioceramics
Bioceramics is a ceramic material used in the manufacture of human "skeleton-muscle" systems to repair or replace human organs or tissues.
Fine ceramics is one of the special values ​​of new materials, which has a bright future. This fine ceramic with excellent performance may be widely used in place of steel and other metals in a large range, to achieve the purpose of saving energy, improving efficiency, and reducing costs; combining fine ceramics and polymer synthetic materials. Make transportation means lighter, smaller and more efficient.
Fine ceramic materials will become veritable high-temperature resistant high-strength materials, which can be used as various heat engine materials including aircraft engines, fuel cell power generation component materials, nuclear fusion reactor wall materials, pollution-free external combustion engine materials, etc. . Fine ceramics, high-performance molecular materials, new metal materials, and composite materials are listed as four new materials. Some scientists predict that due to the appearance of fine ceramics, mankind will re-enter the ceramic age from the steel age.
Detection of specific surface area of ​​ceramic materials
As ceramic materials have become one of the four new materials, the application fields of ceramic materials are increasing, and the specific surface area parameter of ceramic materials has also become one of the important parameters. Along with this, what methods are used to test the specific surface of ceramic materials and how to accurately measure these series of problems has become a problem faced by the majority of ceramic material manufacturers.
Many ceramic material manufacturers, such as Gefeng Technology, Ying Tao Kangshun and so on, chose the ceramic material specific surface area tester produced by Best.
Best Instrument Technology (Beijing) Co., Ltd. is one of the earliest professional companies engaged in the R & D, production and sales of ceramic material specific surface area testing instruments. It is a high-tech enterprise recognized by Beijing Zhongguancun Science Park.
At present, it has ten technical patents. It is the manufacturer of the ceramic material specific surface area tester with the most patented technologies in the same industry in China. It has strong R & D and innovation capabilities. A number of technical patents are specifically used to improve the accuracy and stability of the instrument.
In 2012, it stood out among hundreds of thousands of enterprises, and was selected as a technology-based SME technology innovation fund support enterprise by the Ministry of Science and Technology. It invested special funds specifically for instrument R & D and update, thereby launching a new generation of instruments and bringing the development of the enterprise into a new Stage.
The ceramic material specific surface area tester has successful cases of hundreds of users, including many colleges, scientific research institutions and well-known enterprises, and the sales of the instrument have been far ahead for many years.
In 2009, a production enterprise that passed ISO9001 certification, the ceramic material specific surface area tester has a complete sales, training, service system, and an efficient and professional team guarantees to provide customers with quality equipment and first-class service.
After a year of professional R & D team development, many industry experts participated, international cutting-edge design concept, ceramic material surface area meter has an integrated valve and pipeline design, fully modular assembly, high vacuum and high stability, excellent performance comparable to imported high-end device.
Because most of the foundation is moisture and grease, makeup brushes are resistant to moisture and grease, and can withstand washing, and man-made fibers work well.
Benefits of foundation brush
No dirty hands: This is the main reason why some people switch to Liquid Foundation brushes. Whether you use your fingers or a Powder Puff, the liquid foundation will inevitably get on your fingers, and there is no such annoyance with a foundation brush.
Save foundation: It does not absorb foundation by itself. When it is applied to the skin with better skin on the outer edge of the face, the remaining foundation on the foundation brush can just cover the skin thinly, and the effect of powder makeup changes from thick to thin, soft transition . If you want to save more liquid foundation, spray the brush with water (wet but not dripping) before dipping it, so that the brush will absorb less liquid foundation.
Good makeup effect: Once the foundation brush is used handily, its makeup effect is hardly critical: it is thin and even, and the skin is moisturized and shiny.
