How Does Acrylic Sheet Work Best?

Acrylic is derived from English Organic Glass. It is an important plastic polymer material developed earlier. It has good transparency, chemical stability and weather resistance, easy dyeing, easy processing and beautiful appearance. There are a wide range of applications. Pure acrylic light transmittance of up to 95%, with crystal-like quality, so many acrylic products are treated and treasured as crystal products. How to show the clear and transparent characteristics of acrylic, reflect the value of acrylic crafts, maximize the grade and taste of acrylic crafts, bonding technology plays a decisive role here. Acrylic products are often processed by cutting, grinding, polishing, bonding, etc., and the bonding process is a very critical link in the processing of acrylic products. The fastness of the bonding surface, the transparency and the rationality of the bonding process directly affect the quality of the acrylic crafts. A craftsmanship, crystal clear acrylic crafts will be loved by people, and a rough craftsmanship and lack of aesthetics of acrylic crafts will not cause people's interest, the quality of the bonding process directly affects The beauty and quality of acrylic crafts.

The bonding process of the acrylic sheet is mainly affected by two aspects: one is the applicability of the adhesive itself; the other is the operation skill of the bonding. There are many kinds of adhesives in the domestic and foreign markets, mainly in two types, one is two-component, such as universal adhesive, epoxy resin; and the other is one-component, such as CHCl3 (chloroform). Generally, the two-component adhesive is bonded by a curing reaction, and the one-component adhesive is a final volatilization of a solvent to achieve bonding. 

The two-component adhesive is characterized by good bonding effect, no bubbles after bonding, no whitening, and high strength. The disadvantages are complicated operation, high difficulty, long curing time, slow speed, and difficulty in adapting to mass production. The general one-component adhesive is characterized by high speed and can meet the process requirements of mass production. The disadvantage is that the bonded product is easy to generate bubbles, easy to be white, and has poor weather resistance, thereby directly affecting the outer part of the acrylic product. In the aesthetics and product quality, therefore, in the processing of acrylic products, how to choose the appropriate adhesive, improve the grade and grade of acrylic products, is a big problem that must be solved first in the bonding process. The above two adhesives Both have their advantages and disadvantages and cannot produce the ideal bond. Later, I contacted some acrylic adhesive experts from western developed countries and exchanged adhesive experience with them. They found that they also have a lot of adhesives for various kinds of uses, but they are not suitable for use when they are used, and they are expensive and the effect is not very good. ideal. In the processing of acrylic products, how to achieve excellent bonding effect and easy operation, this problem has been plaguing our work, which is a big problem that must be solved and must be solved. Taiwan's BONLE chemical team is determined to study the bonding problem of acrylic sheets. 

Through a large number of acrylic bonding tests, analysis of the advantages and disadvantages of existing acrylic adhesives on the market, especially in the exchanges with foreign experts, learned a lot of practical knowledge, in people without me, people Under the guidance of my excellent thoughts, a new type of adhesive 3094 shadowless glue was finally born. BONLE brand 3094UV glue This product is specially designed for the bonding of acrylic, plexiglass, PMMA and other plastics. It has moderate viscosity, strong adhesion, convenient operation, fast curing speed, no cure, no glue, no stickiness after curing. Hand, good flexibility, high transparency, no whitishness, no yellowing, no atomization, no air bubbles, good weather resistance, etc., thus achieving the speed, strength and bubble-free required for the bonding operation of the acrylic sheet. Ideal for good adhesion and transparency.

How does Uv glue stick acrylic sheet work best? 1. In order to prevent the acrylic glue from contaminating the acrylic sheet, a self-adhesive method can be used to protect the parts that do not need to be bonded. 2. Grease, dust or pores will affect the uniform coating of the uv glue layer and leave bubbles, which must be carefully removed before bonding. 3. If the amount of uv glue is too small when bonding, it will cause shrinkage during the curing process of the glue, and bring air into the air to generate bubbles. 4. Indoor temperature and humidity and other factors also have a certain impact on the bonding of acrylic products. 5. The stress on the surface of the acrylic sheet, the surface stress and the degradation caused by the cutting tool will affect the bonding effect of the acrylic product. 6. Acrylic materials are chosen to avoid the use of acrylic materials made from recycled materials on the market. 7. The transmittance of acrylic materials and the UV intensity of uv curing lamps of different powers are different. The time of complete curing is different. Before mass production, small batch testing should be done to master the empirical data of complete curing time. It is the action to be careful and slow. Slow work out. When we use 3094 glue to bond acrylic sheet, the first thing we need to do is to wipe the surface of the acrylic board first. It is best to use the master to achieve bonding, so that the bonding parts do not shake, which is beneficial. Improve the quality of bonding. The cross-section bonding with a thickness of 3 mm or less can be uniformly and slowly injected into the 3094 glue from one side by a syringe, and the bonding can be completed by irradiating with a uv curing lamp for 1-2 minutes. 

For bonding with a thickness of more than 3 mm, it can be padded into a thin metal wire, and the sizing can be performed by the principle of capillary action. After the sizing, the wire is extracted before the ultraviolet curing lamp is irradiated, or the tape which can be stuck is not attached. Protect, leave glue on the glue, and then put it into the acrylic plate to squeeze out the bubbles. Irradiate with uv curing lamp for 1-2 minutes
