For cyclists, you must wear attractive bicycle helmets when riding out. However, after experiencing wind, rain, sun, rain, and pasting number stickers, it is inevitable that the helmet will gradually become old.However, it is your fault that the helmet is dirty and smelly, and even the EPS edge of the inner shell is potty, which is caused by improper maintenance.
First of all, maintaining the luster of the helmet shell is a contradictory problem, because the luster of the attractive bicycle helmets are due to the ultraviolet rays of the sun and the dust from the surroundings that are attached to our helmets during daily riding, making it lose its former luster. . Although we can't avoid it, at least we have to find a way to make the gloss last longer.
Remember that bicycle helmets should not be exposed to the sun and frequent rain, or they will be glued soon. There is also a cotton cloth moistened with alcohol or white electric oil to wipe the surface of the helmet every time you come back to remove the stains and dust on the surface of the helmet (never use a harder cloth to wipe the helmet shell). You can also put some wax on the helmet to make it more shiny.
For the inner shell EPS, there is no need for maintenance, but as time goes by, the place where there is no outer shell on the edge will be pitted and not as smooth as before. For those places where the depressions are not deep, we can use the screwdriver's shank part to slightly press the depressed areas around the depressions.
Remember to use a screwdriver to select a round rod and press it back and forth. For those places where the depression is deeper, we use the mosquito incense that is used daily to smoke mosquitoes. We first light it, and then use the lighted part to bake it. The EPS will foam as soon as it becomes hot. Remove the mosquito coil when you see the sunken place and the same place.
The lining needs daily cleaning. When removing the inner lining, do not pull it suddenly with great force, it is very easy to tear off the Velcro and the inner lining together. The disassembled inner liner cannot be washed in a washing machine, nor can it be brushed with a brush. This will easily deform the inner liner and lose its elasticity. Just soak it in water with detergent or detergent for a few minutes, rub it a few times with your hands, rinse it with water, and dry it.
Helmets are witnesses that accompany us through every journey worth remembering. As a must-have, the most important attractive bicycle helmets, it is very stressful. So, for your purse and its light, please treat it normally.
Factors affecting the dimensional accuracy of sand processing equipment
The accuracy of the dimensions is always a critical issue for any part, and sand handling equipment is no exception. But there are often other factors that affect its dimensional accuracy. Let's take a look at the factors that affect the dimensional accuracy of sand handling equipment:
Under normal circumstances, the factors affecting the dimensional accuracy of castings are various, such as the structure, shape and size of the sand processing equipment itself, the influence of the quality of the foam, the influence of the coating, the influence of the molding and casting process in the casting process.
In the entire lost foam casting process, the casting process is one of the most important steps. The four factors of casting system, casting speed, pouring temperature and casting process are the key processes to improve the quality of castings. Only continuous improvement and continuous improvement can be cast. A high quality casting with high precision.
Coating coating also has a great influence on the precision of sand processing equipment. Coating performance and coating thickness can affect the size of the pattern, which affects the dimensional accuracy of the casting. Therefore, in lost foam casting, the coating should have good performance and sufficient strength. The coating application process should be reasonable.
The above is the introduction of the factors affecting the dimensional accuracy of the sand processing equipment, I hope to help everyone. If you still have questions, please feel free to contact us and we will be happy to help you.
The product yield rate is the life of the injection molding enterprise. However, with the long-term operation of the equipment, various dirt condenses on the mold core surface and the mold cooling water path, which not only damages the service life of the mold, but also makes the product yield rate difficult to protect. It has a huge impact on production.
Thorough cleaning of stencils and molds is the key to maximizing mold life, improving mold reliability, and ensuring product quality and yield.
What are the dirt of the mold?
The dirt of the mold mainly exists on the surface of the core and the cooling water path of the mold.
(1) Dirt on the surface of the core: gas / sulfide / glue, oil and rust
(2) Mold cooling waterway: scale, rust, mud
How does the mold dirt form?
The surface of the core is formed by dirt:
Gas, sulfide, glue, etc.
During the injection process of the plastic raw material, the gas generated by the high temperature and high pressure in the cavity, together with the instantaneous exhaust volume of the exhaust groove, can not keep up with the exhaust gas, sulfide, glue and other dirt on the surface of the core.
Oil stain
The thimble oil, high temperature oil applied to the core thimble, the slider, the row position, the rust preventive agent is sprayed, the cleaning agent is not completely evaporated, and the cleaning is not cleaned or migrated to the surface of the core, thereby contaminating the surface of the core.
Rust
The use of mold, water in the storage process, environmental humidity and other external conditions, resulting in the mold is oxidized, resulting in rust spots.
Mold cooling waterway
The external open-type water tower circulating water is in the mold pipeline, and after frequent use of cold and heat for a long time, scale, rust and sediment are generated.
Common cleaning method for mold dirt
Manual cleaning
Laser cleaning
Dry ice cleaning
Ultrasonic cleaning
Electrolytic cleaning
The above is a common mold dirt cleaning method. For used machines to be cleaned frequently, thoroughly cleaning the template and mold is an effective way to maximize the life of the mold and improve the reliability of the mold.

Carbon fiber refers to high-strength and high-modulus fibers with a carbon content of more than 90%, and the high temperature resistance ranks first among all chemical fibers. Acrylic fiber and viscose fiber are used as raw materials and are carbonized by high temperature oxidation. They are excellent materials for manufacturing high-tech equipment such as aerospace.
Since the early 1950s, the Wright-Patterson Air Force Base in the United States has succeeded in the production of carbon fiber from viscose fiber. In 1956, U.S. Union Carbide Co., Ltd. successfully produced high modulus viscose-based carbon fiber and developed stress graphitization. Technology to increase the strength and modulus of carbon fiber.
At present, the main products of carbon fiber are polyacrylonitrile-based, asphalt-based and viscose-based. Each type of product is divided into many varieties depending on the type of fiber, the process and the properties of the final carbon fiber. Each carbon fiber is made up of thousands of smaller carbon fibers, about 5 to 8 microns in diameter.
The carbon fiber at the atomic level is very similar to graphite, and is composed of a layer of carbon atoms arranged in a hexagonal shape, the difference being between the layers. Graphite is a crystal structure in which the interlayer bonds are loose, and the carbon fiber interlayers are irregularly connected to prevent the strength of the slip enhancing material.
The density of carbon fiber is generally 1750 kg/m3. The thermal conductivity is high but the power transmission capacity is low, and the specific heat capacity of carbon fiber is also lower than that of copper. When heated, the carbon fibers become thicker and shorter.
In the late 1970s, the International Union of Theoretical and Applied Chemistry (IUPAC) regulated the classification and naming of carbon fibers. First, PAN (polyacrylonitrile), MP and VS (viscose) are used to indicate the type of carbon fiber, and the lowercase English letters indicate heat treatment temperature such as lht (indicating heat treatment temperature, lower than 1400 ° C), hht (heat treatment temperature is 2000 ° C) Above), and then add a symbol indicating performance (such as HT for high strength, HTHS high strength and high strain, IM medium mold and UHM super high mold, etc.). At the same time, it is pointed out that polyacrylonitrile-based, viscose-based and ordinary-type pitch-based carbon fibers are all difficult to graphitize polymer carbon, while mesophase pitch-based carbon fibers and vapor-grown carbon fibers are easily graphitized carbon.
The carbon fiber manufacturing process generally uses polyacrylonitrile, viscose fiber and other raw materials, first pre-oxidation in air at 200-300 ° C, followed by inert gas protection with carbonization at a temperature of about 1000 ° C, and finally heated to 1500-3000 °C into carbon fiber.
At present, the carbon fiber market in the world is complicated in variety and variety, and brands and products are difficult to count and prices are different. For consumers, it is difficult to buy a carbon fiber product that is desirable in such a market environment.
However, with the advent of high-performance and ultra-high-performance carbon fiber in the early 1990s, it is expected that work will be focused on improving processes, expanding production, reducing costs, and developing applications. With the development of science and engineering, the carbon fiber process will also have great development.
