Characteristics and quality index of copper clad aluminum buckle

Copper clad aluminum buckles are decorated with H62 brass as their surface materials, and their color is similar to that of 18 K gold. Therefore, they have strong decorative properties. After being treated with excellent surface treatment methods, they can ensure long time use without changing colour or rusting.

In addition, the copper clad aluminum button has thin copper surface and few copper. At the same time, the clasp handle of aluminum clad aluminum alloy is made of aluminum alloy to ensure the mechanical strength of the button.

The absolute strength of the handle can reach more than 300N, so that the copper clad aluminum clasp can be used under any conditions without the occurrence of buttons.

Coconut shell is very hard, so it can be used to make buttons.

The buttons are characterized by a light brown to dark brown color, a different color on the opposite side, and spots or filamentary veins on the surface of the buttons.

The coconut shell is lighter in color before immersion, and the color becomes dark brown after soaking.

After bleaching, all kinds of buttons can be dyed.

Compared with wood buttons, the characteristics of the coconut shell buttons are more prominent.

The disadvantages of coconut shell buttons are also similar to those of wood buttons. The main reason is that the water absorbency is too strong, but it is slightly better than the wood buttons.

Coconut shell buttons are mainly used on some casual shirts.

The basic method of anticorrosion of copper is to polish the surface of H62 brass with the method of slightly acid polishing to show its brightness similar to that of 18 K gold.

Then use repeated coating method to dip or spray different protective coatings on the surface.

Among them, the bottom of the dipping lacquer is a kind of paint with good sealing performance to improve its protective performance. The spraying part requires the paint with high hardness to enhance the friction resistance and prolong the service life of the paint film, so as to ensure that the buttons are used for a long time without changing color and rusting.

Emotional symbolism of color

The color of the metal fastener in the clothing configuration also reflects everyone's preferences and emotions. This preference and emotion depend on each person's cultural level, age, gender, social status, nationality, habits and so on. For example, jeans are used to configure bronze fasteners, although their hue is different, but their purity and lightness are close to each other, showing a kind of natural, vigorous, strong personality characteristics.

In the southwest of China, the colorful ethnic costumes with many silver costumes show their mentality of loving beauty and loving life.

Selection of buttons for professional clothing combinations

The style of professional clothing is solemn, neat, and wears for a long time. Buttons are usually determined by various trades themselves.

But the general principle of selection is to embody the characteristics of professional clothing.

In addition to appearance, durability should be considered in terms of quality.

To achieve this goal, light alloy materials or high strength synthetic resins, such as nylon and formaldehyde resin, are often used as buttons on the base, with special logo ornaments to show industry characteristics.

Wood buttons, wood buttons and bamboo buttons belong to buttons made of plant stems.

There are quite a number of these buttons in the international market.

Especially in recent years, as people pursue the greening of environmental quality, the demand for button of these plants has increased, and consumption in developed countries such as Europe, America and Japan has gradually increased.

Wood buttons are the main products in the product structure.

The motivation for people to choose wood buttons originates from the boredom of the long-term use of synthetic plastics.

Many people think that "natural" materials are nontoxic and beneficial to human health, and wood buttons are catering to people's psychology.

Wood buttons with natural wood texture, very simple and natural, and its appearance is rough, and plastic buttons of high gloss feel a sharp contrast.

So these buttons match the hemp fabrics or plain colored casual clothes, and satisfy some people's unconventional and unconventional aesthetic habits.

The main component of wood buttons is lignin, which has strong resistance to organic solvents. Durable detergent can be dry cleaned with clothing.

The fatal drawback of wood buttons is its water absorbency.

Because of the strong absorbency of wood fiber, when it is wet or put into the water, it will absorb and expand quickly. When it is dried again, it will probably crack, deform or become rough.

In order to overcome the shortcomings of wood buttons, we should pay attention to selecting wood dense, long growing and old timber or parts when selecting materials.

After polishing button, high quality varnish is used to treat the surface and seal all the suction holes.

The buttons after such treatment can avoid the problem of easy water absorption.

Transparent injection button

The materials of such buttons include pparent plastic injection molding, such as pparent polystyrene, polycarbonate, acrylic resin (372.613 moulded plastic, etc.), AS resin and so on. The main characteristics of these buttons are as follows: 1. pparent polystyrene button, which has better pparency, cheap material, easy injection, but brittle, and is not resistant to high temperature and solvent, so it can only produce low grade buttons.

2. polycarbonate button (PC) polycarbonate is an engineering plastic, which is not only pparent, but also has excellent mechanical properties, especially its resilience and is not easily broken, so it is mostly used for injection molding with spring buckles.

The disadvantages are high cost and poor injection molding performance.

3. acrylic resin buttons are the most pparent and pparent plastics.

There are many kinds of resins that can be used for injection molding. The main models in China are 372, 613 and 504, but the comprehensive pmittance is slightly worse.

Because of the high pmittance and pure color of acrylic resin, most of the buttons in the manufacturing industry use this kind of material to make high purity and high pparent buttons. Its appearance is like the effect of crystal glass, made of buttons or buttons alone, or combined with other materials to form a combination button, which is popular in women's fashion.

The disadvantage of these buttons is that the surface is wear-resistant, organic solvent resistant and temperature resistant. It is not suitable for high-grade and durable clothing.

4.K resin button K resin is a styrene one or two butene copolymer.

It is characterized by good pparency, good flexibility and easy injection.

The buttons made of this resin often have some elasticity and are used for producing pparent and plucent rope buckles.

Because the resin is limited by the mechanical properties of the material, the buttons are of poor durability and low grade.
