Play it safe, don't let the "Save your life" helmet turn into a "Save your life" pit!
Summer is coming, we still need to wear a helmet to ride a motorcycle, why?
Mask in February, machine in March, melt-blown cloth in April, helmet in May! When man sits at home, melons come from heaven.
In the melt-blown cloth swimming has not come ashore, the new "flow star" helmet and fierce!
The original will bring goods not only the network red anchor, but also the Ministry of Public Security traffic management Bureau! What's going on there?
The Traffic Management Bureau of the Ministry of Public Security recently issued a notice that from June 1, a nationwide "helmet belt" safety operation will be launched to correct motorcycle and electric bicycle riders who do not wear safety helmets and car drivers who do not use seat belts. (" Helmet "refers to the helmet; "Belt" is the seat belt)
Relevant research results show that when an accident occurs, the riding helmet can absorb most of the impact force, play a buffer, shock absorption protection role, can make the proportion of injured by 70%, mortality by 40%.
The helmet is on fire! The raw material of the helmet rises!
Some people have estimated that the current social ownership of 300 million electric vehicles, electric vehicle helmet ownership is less than 30%, then at least 200 million more helmet demand.
Suppose that the average use of a helmet shell plastic is 500g, the potential market amount of electric bicycle helmet plastic is 200 million *500g/ only = 100,000 tons.
Under the epidemic, in addition to melt-blown materials, can modified plastics find a better incremental market than this? It smells good!
Now, in the circle of friends, the heat of the safety helmet has overshadowed the meltblow material.
and there are those who already close to recommend helmets testing equipment:
then ask a friend! What is the raw material of helmet that?
What are the main materials of the shell?
1, the common is the resin material of ABS, which is an engineering plastic, strong impact resistance and good dimensional stability. The material helmet market price: usually full helmet between dozens to one hundred.
2, PC alloy material is better than ABS, the strength and toughness are improved a lot, and the low temperature impact performance is also improved a lot. At present, Chinese alloy materials are widely used in helmets.
3, FRP is better than ABS, lighter and stronger, but it is also more difficult to do, the output is lower, so it is also more expensive than ABS.
4, the best should be carbon fiber, very fast, light weight, high technical content, very expensive! (This material can be used to make fishing rods).
5, PP material can only be made of children's protective helmets, the quality is very light and comfortable to wear, but the safety is poor.
protective foam filler
helmet buffer layer are expanded polystyrene (EPS), foamed polypropylene (EPP) and thermoplastic polyurethane (PU) ) material, etc.
Helmet lining materials are usually polymer foams, mainly because they are easy to process and their ability to absorb energy is more comprehensive. The foam pad is placed between the inner shell and the outer shell, filling the space between the inner shell and the outer shell, and playing the role of cushioning and shock-proof.
EPS foam
EPS, referred to as flexible polystyrene, commonly known as foam, is a thermoplastic material, different from the general ordinary foam material, after heating foaming, each cubic meter volume contains 300— — 6 million independent sealed bubbles, containing more than 98% of the air volume.
EPS foam polystyrene foam material, mainly because it is a kind of high impact resistance material, with seismic buffer effect. Its low density and light weight are also one of the reasons why this material is applied to safety helmets.
EPP foamed polypropylene
Another lining material EPP foamed polypropylene, also has a good buffer effect. EPP is a high crystallization polymer/gas composite material with excellent performance, and has become one of the fastest growing new anti-pressure buffer insulation materials with its superior performance.
Classification of helmets
According to the different protection positions, helmets are divided into full helmets, 3/4 helmets, half helmets and flip helmets are also called uncovered helmets (uncovered helmets do a good brand Italy Caberg (Caberge), Germany Schuberth (Schubert)) four, the above four helmets, as far as safety is concerned, full helmet ≥ Uncovered helmet > Three-quarter helmet > Half helmet & GT. The specific advantages and disadvantages are as follows:
According to the applicable object, the helmet can be divided into two categories: A type helmet and B type helmet, A type helmet is suitable for the total displacement of 125cc or more motorcycles, the shape of the helmet and half helmet two kinds; Class B helmet is suitable for motorcycles with A total displacement of 125cc below, and its volume and weight are smaller than class A helmets, and the shape is all half helmets.According to the different material, and divided into many kinds, such as ABS material, PC, FRP material, and so on. The general bicycle helmet is polyester vinyl, and the safer ones use carbon fiber.
According to the different use of the scene, it is also divided into motorcycle helmets, bicycle helmets, hard hats, VR helmets and so on.
National standard of helmet National standard: The current mandatory national standard version is "Motorcycle occupant helmet" (GB 811-2010). According to the requirements of the "motorcycle occupant helmet" (GB 811-2010), the qualified motorcycle occupant helmet needs to pass the detection of 10 items such as "field of vision", "goggles", "stiffness performance", "collision energy absorption performance" and "penetration resistance", among which, "Collision energy absorption performance" and "penetration resistance" are representative indicators of helmet safety protection performance.
CCC certification: October 2017, Aqsiq and CNCA issued the "Announcement on the release of Motorcycle Occupant helmet, electric blanket, mastic products to mandatory product certification management transition period arrangement" (2017 No. 86) required in November 01, 2017 to officially implement mandatory product certification management of motorcycle occupant helmet products, August 1, 2018, Motorcycle occupant helmet not obtained CCC certification, may not be factory, sale, import or use in other business activities.
motorcycle helmet crew national standard and CCC certification rules
quality identification: Qualified motorcycle occupant helmet, must pass the mandatory national standard "motorcycle occupant helmet" (GB 811-2010) provided for the certification test, and by the corresponding factory quality assurance ability audit, in order to pass the mandatory product certification (CCC certification). The global mainstream qualification marks include, the United States Department of Transportation's ordinary road specifications (DOT), international recognized racing specifications (SNELL) and European specifications (ECE), of which SNELL is more stringent than DOT, as long as there are three of them, are more secure.
SNELL: A non-official standard developed by a third-party independent laboratory in the United States. In 1956, a racer named William Pete Snell died after suffering a severe blow to the head during a race. In his memory, his relatives, friends, and a group of scientists and racers established a non-profit memorial Foundation in his name in 1957, dedicated to research, education, testing, and development of the nature of human head injuries in vehicle motion and helmet standards. The SNELL Foundation was established in 1957. The Snell Foundation has a board of directors to oversee the foundation's operations. The members of the board are mainly medical experts and scientists, who are experts in the field of head injury and safety. Since its inception, SNELL has been a pioneer in helmet safety in North America and around the world. Snell's testing requirements are extremely rigorous, and the standard is updated every five years, with the latest standard being M2015.
The biggest feature of SNELL certification is that different test standards are provided for different purposes of the helmet. Snell certified helmets can be worn on the track.
When selecting helmet suppliers, buyers can check the factory's CCC certification and product quality inspection report; When the user purchases the helmet, he can identify it by the "CCC" mark pasted on the helmet, and do not use the helmet that has not passed the CCC certification.

Production helmet need to buy injection molding machine, mold opening, purchase raw materials, drying bucket, suction machine, manipulator, etc., after the process of painting, printing, assembly, packaging and shipping, equipment, supporting products, etc.
In the mask melt-blowing cloth ushered in the era of survival of the fittest, safety helmet heat skyrocketing, related material enterprises, processing enterprises, equipment enterprises benefit, will undoubtedly usher in a wave of development of small peak.
in the market need to be careful
masks make money market, has its special background. Mainly because of the epidemic, masks are just demand, and masks are consumable products, the demand is huge. In addition, the production capacity of masks is slowly improved, which is greatly affected by the raw material melt-blown cloth.
Xiaobian recently learned from a number of channels that after April, most of the small enterprises that entered the production of melt-blown cloth are now wiped out, and some people have been ruined.
Helmet It is not consumable, buy one can be used for a long time; It is not just needed, the price is too outrageous, you can not ride electric vehicles; Low technical content, cheap raw materials and fast capacity improvement.
Therefore, the market of helmets will not last long, and the price will not rise very far. If factories want to, they can increase the supply, and soon the supply and demand will be in balance.
Be careful what you fry!
Xiaobian wants to say, the business opportunity is coming, but remember that the helmet is used to save life, can not be in order to make helmets and corners, shoddy. I also hope that colleagues in the industry operate in good faith, do not bid up the price, and work together to create a rational and healthy plastic industry ecology.
