High Reflective Index Glass Beads

• High refractive index glass microsphere / beads is a key raw material for the production of refractive stuff, which mainly include refractive film, refractive ink, refractive line-mark paint, refractive cloth, refractive leather, refractive textile band, refractive security silk, etc.

• Refractive stuff is featured by retro- reflection, therefore enjoys high regressive refraction effect without consuming extra energy. Since it congregates and refracts nearly all the ray of light within a very small angle, its luminance greatly exceeds what the common stuff can achieve. This is the reason why it is widely applied to the fields such as road, harbor, mine, fire department. As a security mark, it highly improves users’ safety reliability.

• Retro-refraction Theory:High refractive glass bead can be regarded as a spherical lens. Adding a refractive layer to the focus, the spherical lens is able to regressively refract the entry light to the original source. The location of the glass bead focus depends on the refraction rate of the bead. Based on the location of the glass bean at refractive stuff, it can be divided into Exposed-lens type and Encapsulated-lens type.Exposed-lens Type : Glass bead is located at the front surface of the refractive stuff, which directly interact with air. This type of material has simple structure and high refraction. However, it can only refract non-color light. What’s more, the surface is easily adhered by dust and refraction rate decreases in the rainy days. The application of this type of materials include refractive cloth, refractive paint. It can also be found in most refractive clothing.

• • Encapsulated-lens Type : Glass beads are buried into transparent rosin, which interact with air. This type of material

performs well despite of the weather condition. It can refract colorful light, dust-free on the surface and maintain high refractive rate in the rainy days. However, the structure is complex, claiming high requirement of both equipments and processes. It is mainly applied to various refractive films and can be found in the express way.

Breath Cooling Waistcoat • Functional features of breath cooling waistcoat are • Refrigerative and Dustproof

• Breath Cooling Waistcoat is our latest body cooling equipment specially for the staff who work under heat stress. The equipment has similar shapes with armoured vest. When the worker puts on the Waistcoat upon, it can cool human body and never influence ordinary work. The core technology of the equipment is independently developed and operated by us. As soon as the product appeared on the market, it has been consistent high praise by the domestic, external experts and the consumers. Because of the patent technology, our company quickly becomes the worldwide leader of body cooling.

Breath Cooling Waistcoat • Breath Cooling Waistcoat is different from traditional cooling waistcoats and its function has achi

eved a qualitative leap: the main cooling goal are targeted on the body's internal organs and the brain, and not only on the surface or skin of the human body.It activates body natural temperature regulation system directly led by respiratory system, though which the heat accumulated in the internal organs and the brain can be transferred to the air, then the temperature in vivo remained on a normal physiological condition,so the users no more feel irritancy and anxiety,

• furthermore, the users feel more clearly.This waistcoat has a unique combined lung protection system.In the environment with heat and high dust concentration, the waistcoat not only can cool the body and let users comfortably work, but

• also can create fresh and clean air for users in order to effectively reduce the occurrence of lung occupational disease.

• Breath Cooling Waistcoat is particularly applicable to the building industry in the tropical region such as africa, the middle east. Even in 60℃ region, the product could still maintain well cooling effect, and the users couldn’t fell palpitation,

• dyspnea, vertigo.

Breath Cooling Waistcoat

• Functional characteristics:

• 1. Mainly cooling in vivo. The theory of cooling is directly targeted on the body's internal organs and the brain which rarely eliminate heat from the body.

• 2. Cooling by the body surface or skin concurrently. By the body surface or skin, the waistcoat can cool chest, stomach, dorsum and waist, which product more heat than other organs.

• 3. The unique combined lung protection system.Because the system can filter air by many ways for many times, and effectively remove vapour, fog, smoke, dust and fiber from the air inhaled by the users, the users can breathe fresh and clean air in order to effectively reduce the occurrence of lung occupational disease.

• 4. The best appearance. The Waistcoat’s appearance is designed according to the frame and form of “BLACK HAWK WAISTCOAT” used by the US Marine Corps. The waistcoat has characteristics such as comfortable and aesthetically pleasing, not affectting the body’s movement

Breath Cooling Waistcoat

• 5. International standard and well adjustability. To ensure that all peoples with different height and size can use it, the waistcoat ‘s design adopt the international size standard, and adjustable shoulder straps and belt for the user’s comfort.

• 6. Environmental friendliness and safety. The material of the waistcoat used new TPU composite fabric with waterproof, nontoxic and environmental friendliness for the user’s safety.

7. Burden changeability. The waistcoat has many positions for internal energy ice bag.

The users can decide ice bag number of the waistcoat according to actual demand for the user’s burden changeability.

• 8. Adjustability of decalescence speed. The users can adjust decalescence speed by their self according to their physical quality. The waistcoat can meet the demand of different constitution users.

• 9. Internal energy ice bags adopt the new biomaterial, and can be put cold thousands times for recycling

•

Breath Cooling Waistcoat• Fields of application• 1. Metallurgical industry: ferrous metal smelting, steel-smelting, steel rolling, coking, non-ferro

us smelting, et al.

• 2. Machinery industry: casting, forging, heat treatment, welding, et al.

• 3. Chemical industry: oxidation, synthesis, heating, chemical reaction, et al.

• 4. Glass, enameled, pottery industry ： combustion chamber, coil base, calcination and firing, oasthouse, kiln, et al.

• 5. Light industry: steaming in Papermaking industry, roistering in candy/food industry, sulfuring in rubber industry,heat pressing in plastic industry, et al.

• 6. Textile industry: heating or steaming of printing and dyeing, reeling silk, et al.

• 7. Building materials industry ： the furnace in refractory material industry, brick and tile oven and the cement sintering, et al.

• 8. A variety of heating furnace, boiler, et al, in other industry.

• 9. Summer outdoor work: construction and operation, dock, road construction and strip mining, et al.
