Application of UV Adhesive in Metal Bonding

Glass-bonded metal UV glue, often referred to as metal aluminium and stainless steel, metal aluminium is the most widely used in glass furniture, such as aluminum cake on several feet of the tea table, metal aluminium cake on the door of the TV cabinet switch; and the bonding with stainless steel is often reflected in the cover and frame of watches and clocks.

 

Firstly, the bonding between aluminium cake and glass should focus on the strength after bonding. As mentioned above, the strength is a non-perceptual concept. In the process of using this UV adhesive, the following points should be paid attention to:

 

1. Viscosity of Glass-Bonded metal UV adhesives, the general customers will think that the greater the viscosity of the adhesives, the better the quality of the adhesives, which is also taken into account in our production process. Generally, the viscosities of Glass-Bonded metal are more than 1000 Mpa/S (MPa/s).

 

2. Whether Glass-Bonded metal UV adhesive is rigid or flexible after curing, if it is rigid after curing, then it can not be treated after bonding failure. If it is flexible after curing, once bonding failure, it can be bonded again. Our company's glue is also flexible. Ultra-low-cost glass-metal glue is generally rigid, which is closely related to the formula of the glue. There are too many hard monomers in the formula.

 

3. Sticking large or small aluminium cakes is also a name without definite concept. The reason why there is such a call is that some manufacturers use some inferior glue now, and the corresponding glue sticking large aluminium cakes is definitely higher than that sticking small aluminium cakes in price.

 

2. The bonding between stainless steel and glass or crystal glass is mainly used on the cover of clocks and watches. As an ornament at present, clocks and watches are priced at middle and high end consumers. Therefore, the following points are emphasized:

 

1. Glass-bonded metal UV glue has no shadow after bonding. If the traces can be seen after bonding, the glue can not be used. Of course, our company's products can guarantee no shadow.

 

2. Whether Glass-Bonded metal UV glue can seep in the bonding part is also a point emphasized by clocks and watches. At present, watches are mostly marked by "three preventions", waterproof, vibration-proof and pressure-proof.

 

Advantages of UVLED curing light source for optical glass:

 

1. No toxic mercury, no heat radiation, no damage to cured products, safer and more environmentally friendly.

 

2. Mercury vapor arc lamp with higher luminous efficiency and spectral radiation power equivalent to several kilowatt; low power consumption and service life of 20000-30000 hours

 

3. Small volume light source and power supply design, accurate ultraviolet spectrum irradiation, high luminous purity, stable light output

 

4. UV curing machine is suitable for many kinds of substrates: flexible or rigid, absorbable and non-absorbable materials.

 

5. The LED irradiation head is controlled by computer CPU. It can choose manual or automatic control operation according to actual needs, and set the time needed for irradiation by itself.

 

6. Optical glass UV curing machine can be cured quickly, so it can greatly shorten the production time and improve efficiency.
