Why use ramps?
Unlike humans, a dog can walk upright on two legs. Its body structure determines that it must walk on all fours. However, when a dog climbs stairs, the plane width of the steps is very narrow, which cannot satisfy the dog’s four limbs at the same time. on one level.

If dogs climb steep stairs for a long time, it is easy to cause intervertebral disc herniation, hip joint wear and tear, and even paralysis. Especially for those dogs that are larger in weight but smaller in size, such as British cattle and French dogs, climbing stairs is a torture for them.

Old people are not recommended to climb stairs, regardless of dog breed or size.

An Open Letter to Kylian Mbappé

Kylian,

The old adage that football is just a game where 22 men and up to three substitutes from either team kick a ball around for 90 minutes is one that classically frustrates the ardent football fan.

After all, the sport is a global, money-making machine with a vast array of intricacies from tactics to squad dynamics, from boardroom politics to local rivalries. The sheer variety of skill-sets required to run a functioning football club, much less a functioning football league make this sport excitingly nuanced, because the complexity of football ensures that unexpected success or catastrophic failure are both ever-present possibilities.

But at its core, what is football? It is a chance at victory, glory; what every fan hopes for. On its most human level, football also has the capacity to inspire. The adoring story of underdog Leicester City’s Premier League title win last season captured the hearts and minds of the world. Although it is a team sport, in an ever-increasingly commercialised game, the onus in recent times to inspire or at least act as a role model has fallen at the feet of the individual, the player, rather than on a team as a whole.

Yet this letter Kylian is not about the probable multi-million Euro sponsorship deals that you are surely already being lined up for by the big sportswear companies, nor is it offering marketing advice, about how you should surely be coming up with your own unique dance celebration in order to boost your brand.

You see Kylian, if one looks past the relatively recent mass-commercialisation of the game for just a second, you realise that 21st century football fans are undeniably inspired by talent, much like the generations before them. The vast majority of football fans have played the sport to some degree, and therefore have an appreciation for raw ability.

For example, a sequence of pieces of technical skill from Lionel Messi, where he beats three or four players of a La Liga standard before tucking the ball in the back of the net, as he appears to have achieved at a superhuman level of regularity throughout his career, is something that they could never reproduce. They have an understanding of how much work, dedication and ingenuity is required to reach such a level of excellence in the game.

From that standpoint, it becomes easier to understand how millions of individuals around the world can be inspired by a footballer without him even having to open his mouth, without him having to fight for any other honourable cause apart from the success of his team.

You see France is falling in love with you Kylian, as are parts of Europe.

Why? Because you have shown dedication, because you have shown fearlessness and because you have shown yourself to have an ability and an instinct that is verging on supernatural.

An ability that suggests you might have the potential to join an elite set of footballers in the game’s history who inspired millions with simply what they do with the ball at their feet. An instinct that only the world’s best and most ruthless are blessed with.

Remarkably, you have made an entire nation take notice of you at merely 18 years of age. All this, whilst consistently offering both considered and humble words when speaking to the media. You appear to have struck a balance between never seeming to be in a hurry to get away from reporters whilst not spending a second longer than club duties dictate you must in front of the cameras after matches – a feat that many professional footballers never achieve.

Now maybe none of this has occurred to you yet, and perhaps that is a good thing. You appear to be dealing with the added media attention, that comes notably with being the first ever player in French football history to be born after the 1998 World Cup success to be called up to play for your country, with aplomb. Your family appears to have your best interests, namely your progression on the football field, at heart.

I hope that you are grateful for this: many of the most talented French football players of the 21st century have had their careers blighted by surrounding themselves with the wrong people. During a period in your life when everything appears to be changing, the amount of attention you are receiving, your playing time for club and country, your salary, sometimes the only constants are the people that loved you before anyone had even heard of Kylian Mbappé.

Hold them close to you, because they are the only people that you can be sure will be there for you during the invariably darker periods that come with the highs and lows of a career in professional football.

The main purpose of this letter Kylian is to warn you. At Get French Football News, we watch tens of precocious talents leave the realm of French football for the Premier League too soon. To the point where they do irreparable damage to their careers.

In the summer of 2015, Anthony Martial made the decision to leave AS Monaco, where he had been guaranteed a starting spot in the central striking role for the 2015/16 campaign, for Manchester United for the sort of fee of that your talents would likely command in this ever-inflating marketplace.

18 months later and Martial’s Premier League stay has been diabolical. Not necessarily for him, I cannot speak for him, but perhaps for his career and certainly for French football. He had the potential to become a world-class centre forward, to achieve in the self-proclaimed “best league in the world” what only the likes of Thierry Henry has achieved as a Frenchman.

But he went too soon. He did not have enough experience as a centre-forward, he did not even play a whole season in that position for Monaco. The result? He flits in and out of José Mourinho’s Manchester United side, with no consistency in terms of performance or confidence. When he does play, he is exiled to the left-wing, his pace used almost like a gimmick, restricting him to the sort of one-trick pony status reserved for squad players when he should be improving his technical and positional abilities holistically as a central striker to fulfil his status as one of the world’s most devastating attacking talents. Monaco was the platform where he could achieve that.

Kylian, Europe’s biggest clubs are after you, but don’t make the mistake of thinking you have seen all that Ligue 1 has to offer you yet.

Leonardo Jardim is developing a reputation as one of the most formidable developers of young talent in Europe, Monaco have a project centred around giving quality players consistent game time, regardless of their age and with the new investment in Lyon, Nice, Lille and Marseille, the French top flight next season will be stronger in terms of competitiveness and quality than it has been in the 21st century.

Harness your tremendous talent and sign a new contract with AS Monaco. Don’t fall for the advances of the Premier League’s millions. At least not until you are comfortable within your newfound status and happy that you have taken everything from your adventure with Monaco that there is left to take.

You have the potential to inspire a generation of football fans and with patience and humility you will prevail. Why put all of that in jeopardy by pulling the trigger too early and skipping over necessary steps of development and maturity at your first footballing home?

It is time that one of French football’s great prospects made smart early career decisions. Kylian, we are all counting on you.

Congratulations for everything so far.

Best of luck with everything to come.

Look after yourself.

What is Powder Coating?

Click:Snus Bag Packaging Machine

Powder coating has become a popular type of surface finish in the CNC machining and manufacturing, as it helps protect metals from external influences like rusts and scratches.

This technique enhances not only the aesthetic appeal but also the durability of products, making it a crucial component in various applications.

This comprehensive guide focuses on everything you need to know about powder coating, and if it’s a more advanced approach compared to other types of coating.

What is Powder Coating?

Powder coating is a dry finishing process, where a powder material, typically a polymer resin mixed with color pigments, hardeners, and other additives, is electrostatically applied to a surface, cured under heat to form a skin-like layer. This method is favored for its ability to produce a tough, uniform coating on metal objects without the environmental drawbacks of traditional liquid paints.

Short History of Powder Coating

Powder coating, a term synonymous with durability in manufacturing, traces its origins back to the mid-20th century. Daniel Gustin, a pioneer in chemical engineering, revolutionized surface finishing techniques with the development of this process. Officially patented in 1945, as evidenced by US Patent 2538562, powder coating emerged as a robust alternative to traditional paint methods. This innovation provided industries with a more efficient, environmentally friendly way to apply protective and decorative coats to a variety of materials, notably metals used in manufacturing and CNC machining.

What Is Powder Coating Made Of?

At its core, powder coating consists of several key components, each playing a pivotal role in its performance and aesthetic qualities. Here’s a breakdown of the main ingredients:

  • Polymer Resin: The backbone of powder coatings, polymer resin forms the protective and adhesive layer upon curing. It is typically a thermoset or thermoplastic material, which determines the coating’s durability and heat resistance.
  • Additives: These substances enhance the powder’s properties, such as flow characteristics and UV stability, ensuring the finish can withstand various environmental factors without degrading.
  • Pigments and Dyes: Responsible for the vibrant and diverse colors seen in powder-coated finishes, pigments are added to the mix before it is applied to the surface. These not only contribute to the aesthetic appeal but also improve coverage and opacity.
  • Fillers: Used to reinforce the coating, fillers can improve its mechanical properties, such as impact resistance and texture. They are integral in applications requiring enhanced durability, like automotive parts and outdoor furniture.

What are the Different Stages of Powder Coating?

The powder coating process is a complex yet meticulous procedure that transforms a plain metal surface into a vibrant and durable finish. This method involves several critical stages, each designed to ensure the longevity and quality of the coating. Understanding these stages not only enhances the effectiveness of the process but also ensures optimal adherence and finish quality.

Surface Preparation

Proper surface preparation is paramount in the powder coating process, as it directly affects the adhesion and overall quality of the finish. This initial phase involves cleaning and pre-treating the surface to remove any oils, dirt, or contaminants that could impair the coating’s ability to bond with the material. Effective preparation provides a clean and reactive base that enhances the coating’s durability, making it resistant to chipping, flaking, and corrosion.

Blasting

The first step in surface preparation is blasting, and it involves using abrasive materials to thoroughly clean the metal surface. This technique not only removes existing coatings, rust, or scale but also roughens the surface to improve the mechanical adhesion of the powder coat. Typically, materials like sand, steel grit, or other specialized media are propelled at high speeds across the surface, ensuring it is optimally prepared for the subsequent application of powder coating.

Cleaning and Degreasing

Another important step in surface preparation for powder coating is cleaning and degreasing. This phase ensures the removal of all contaminants such as oils, greases, and dirt from the metal surface. Effective cleaning is paramount as it prevents defects in the coating process and ensures a strong adhesion of the powder. Various methods, including solvent cleaning and alkaline washes, are employed depending on the substrate and the type of impurities present.

Pretreatment

Following cleaning, pretreatment plays a vital role in promoting the durability and quality of the powder coating. Pretreatment typically involves several steps:

  • Alkaline Cleaning: Further cleans the surface by removing any residual contaminants and providing a chemically reactive surface for subsequent treatments.
  • Iron Phosphate Application: This step enhances both paint adhesion and corrosion resistance, critical for components exposed to harsh environments.
  • Rinsing: Thorough rinsing with reverse osmosis water removes all phosphate residues, ensuring a clean surface ready for the next treatment.
  • Zirconium Sealer: An application of zirconium sealer helps enhance the powder adhesion further and provides a barrier against oxidation, extending the life of the powder coating.

Primer

Applying a primer is a critical step in the powder coating process, especially for metal substrates. This stage involves applying a preliminary coat that helps to enhance the adhesion of the powder coat and increases corrosion resistance. Primers are essential for ensuring a long-lasting and durable finish, particularly in applications exposed to harsh environmental conditions.

Masking

Masking is utilized to protect certain areas of the substrate that should not receive powder coating. This technique involves covering specific parts of the object with tape, silicone plugs, or other resistant materials to prevent the powder from adhering to these areas during the application process. Effective masking ensures precision in the coating process, maintaining the functionality and aesthetics of parts with complex designs.

Application Techniques

Powder coating is applied using a variety of methods, each suited to specific types of materials and desired finishes. Here are the primary techniques used in the powder coating process:

  1. Electrostatic Spray Deposition (ESD): This is the most common method, where powder coating is applied using a spray gun that imparts a positive electric charge to the powder, which is then attracted to the grounded workpiece. This method provides a uniform layer and is efficient for coating large volumes of metal parts.
  2. Fluidized Bed Application: In this technique, preheated parts are dipped into a tank containing powder particles that have been aerated by passing air through a porous plate. This causes the powder to adhere and melt onto the surface, forming a smooth coating after curing.
  3. Electrostatic Fluidized Bed Coating: Combining the principles of electrostatic spray and fluidized bed techniques, this method charges the powder in a fluidized bed, and the part is passed through the charged powder cloud. This allows for thicker coatings compared to the spray method.
  4. Magnetic Brush Coating: Used for small parts or intricate shapes, this method uses a magnetic brush-like device that directs the powder to specific areas of the part.
  5. Thermoplastic Dip Coating: Parts are preheated and dipped into a tank of fluidized thermoplastic powder, where the heat of the part causes the powder to melt and adhere to the surface.

Curing Process

The curing process is crucial in powder coating, as it is the phase where the applied powder is transformed into a smooth, hard finish. Curing typically occurs in a specialized oven where the coated parts are heated to temperatures that range from 180°C to 210°C (356°F to 410°F), depending on the type of powder used. This heat reacts chemically with the polymer resin systems in the powder, causing them to cross-link into a solid film. The curing time can vary from 10 to 20 minutes, again based on the specific properties of the powder.

Curing is essential not only for achieving the desired level of hardness and durability of the coating but also for ensuring the finish is uniform and free from defects such as drips or bubbles. Properly cured powder coatings provide excellent resistance to weathering, chemicals, and UV light, making them ideal for both indoor and outdoor applications.

Thermoset Curing

Thermoset curing is a critical phase in the powder coating process where the coated item is heated in an oven, causing the powder’s chemical structure to change irreversibly. This reaction results in a highly durable network of polymers that provides superior performance characteristics such as high resistance to chemicals, wear, and heat. The typical curing temperature for thermoset coatings ranges between 180°C and 200°C (356°F to 392°F), with the time and temperature adjusted based on the specific properties of the resin used in the powder.

UV Cure

UV curing is an innovative technique in powder coating that utilizes ultraviolet light to cure the coating instead of heat. This method offers the advantage of significantly faster curing times and reduced energy consumption. When the UV light hits the coated surface, it triggers a photochemical reaction that instantly cures the powder. This method is particularly useful for products sensitive to high temperatures and those requiring rapid processing. UV curing not only enhances production efficiency but also contributes to a lower environmental footprint of the coating process.

What are the Different Types of Powder Coating?

There are various types of powder coating available, meaning you have a wide range of options to select from. However, two of the most popular types are thermoset and thermoplastic powder coatings, each serving distinct purposes and offering unique benefits.

精选最顶级的原厂头层牛皮制作而成。

皮料的金字塔等级分类图

我们采用的是A部分最顶级的原厂头层皮A+B=头层皮料

头层皮大约占整个动物皮料的1/9,因此头层皮特别珍贵,它保持了皮料自身的天然属性,是最有质感和肉感,毛孔清晰细小,富有弹性和透气性。

A粒面皮:选用最顶级的进口头层皮,保留了皮料自身的天然粒面,是最接近牛皮本身的质感肉感,没有经过太多的人工优化。

B修面皮:修面皮料本身瑕疵多,或肉感不好,需要人工修面来降低瑕疵提高利用率,但失去了完美的手感、肉感和香气。

C二层皮:真皮的下面一层,经化学材料喷涂或覆盖上薄膜加工而成,虽有一定的弹性和可塑性,但强度较差,

D再生皮:将二层牛皮的碎屑压成再生二层皮,再加上PVC人造皮层。

颗粒纹牛皮

我们的颗粒纹牛皮,皮革中最经典的一种,也是最常见的,许多的包包中都有出现,

特点:颗粒小且饱满,防水耐用,哑光质感高级感十足,有天然的颈纹的纹理。

来源:颗粒纹皮革取自公牛皮颈部,天生带纹理,每张皮子的纹路深浅、纹路大小都不一样,颗粒纹牛皮韧性很好,颗粒小也相对饱满。

鳄鱼纹牛皮

我们的鳄鱼纹:选择进口皮胚,自己反复推敲设计仿真鳄鱼纹肚皮纹路,双色立体感,少有的既有含蓄光泽,又有高级质感的鳄鱼纹,可以和红宝三打磨稀有鳄鱼皮媲美。

特点:耐磨抗造,纹理感和光泽感十足

来源:鳄鱼纹皮是头层牛皮压纹所制成,而非真鳄鱼的皮。

摔纹牛皮

我们的摔纹牛皮:来自意大利知名的皮料供应商——GR工厂,奢侈品御用原厂皮,摔纹是自然收缩纹理,皮料每个部位纹理是不一样的,每个包包都是独一无二的。

来源:是把皮在转鼓里摔来摔去形成一种比较自然的纹路,质感较好,没有经达机械压纹的。

手搓纹牛皮

特点:手搓纹是赛琳和爱马仕共用的独立皮料,横向纹足和平纹最大的区别就是手搓纹横纹很紧绷,纹理是细细的不太规则的横纹理。

来源:手搓纹是通过手工师傅用大拇指指腹逆着毛孔方向揉搓而形成的工艺性纹理。

鱼子酱牛皮

特点:硬挺有型,手感高级,肌理感和颗粒感很强。

来源:鱼子酱我们选的是顶级头层牛皮压制而成,不光纹路立体感好。

手感和香气也非一般皮料比拟,在牛皮表面做出的凹凸颗粒感像鱼子酱,所以叫鱼子酱牛皮。

山羊皮

特点:山羊皮纹很轻,纹路低调华丽,爱马仕家的小皮具选用了很多,耐磨度高于羊皮和小牛皮。

树纹胎牛皮

特点:树纹胎牛皮,来自全球最大的奢侈品皮料供应商,皮料粗旷自然,

手工搓出树纹,特殊工艺海绵托底,皮质特别轻盈,而且香香哒。

天然牛皮的特征

保留牛皮天然的味道

1:因为意大利畜牧业发展程度较高,

气温适宜,牛吃的草品质较好。

2:做皮料的时候加入几味当地纯天然的植物精华和秘方配比,故意大利的头层牛皮会有皮料

特属的香气,会给人带来美好的幸福感。

牛皮的肋部伤痕

关于牛皮的肋部伤痕

所谓肋部伤痕是指牛在活动时在身体上所留下来的伤痕,有些狂野的感觉。

牛的助部约占全身的百分之七十左右,而这也是皮革最常运用的部位。

有些匠人会刻意保留这些伤痕,凸显出作品的独特性。

皮料的天然皱纹

有时尚牛皮在加工处理后,会浮现像老虎斑纹的痕迹,这是牛天然的皱纹,和人一样的皱纹。由于牛有低头吃草的习性,因此大部分会出现在牛的脖子到肩膀部分,呈现大片的纹路状。
