Glass is something we came into contact with within the early days. In our opinion, transparent products are generally made of glass. We never thought that one day glass will be eliminated by acrylic sheet products. Maybe acrylic products are constantly improved based on the disadvantages of glass. Glass instead. Let me explain to you the main reasons why acrylic sheet products replace the glass.

1. The light transmittance of the acrylic sheets is very good, the light transmittance is above 92%, while the light transmittance of ordinary glass is 85%. Therefore, dyed and colored acrylic craft products are crystal clear and very beautiful under sunlight.

2. It has a very good insulation effect, which should be found in many electronic products. For example, some very small component insulators are used in products such as tablet computers, mobile phones, computers, stereos, and televisions. If you pay attention to electronic products when they are being repaired, you can see them all.

3. The weather resistance is very strong. It will not turn yellow or become broken due to exposure to the sun, freezing, and other reasons, so it is very convenient for you to clean it.

4. The freedom of shaping is very high. Can be processed at will to become the type you want very much.

5. The anti-corrosion ability is very strong.

The adhesion of acrylic products is a key process in acrylic processing. How to show the clear and transparent characteristics of plexiglass, reflect the value of tobacco and alcohol packaging crafts, and maximize the grade and taste of acrylic crafts, bonding technology plays an important role.

The bonding of plexiglass is mainly affected by two aspects: one is the applicability of the adhesive itself; second, the bonding technique.

There are many adhesives on the domestic and foreign markets, there are mainly two types, one is two-component, such as universal glue and epoxy resin; there is only one component, such as CHCl3 (chloroform). Generally speaking, two-component adhesives are bonded through curing reaction, and one-component adhesives are finally volatilized by solvents.

Two-component adhesives have the characteristics of a good bonding effect, no bubbles, no whitening, and high strength after bonding. The disadvantage is that the operation is complicated, difficult, long curing time, slow speed, and it is difficult to meet the requirements of mass production. The common one-component adhesive is characterized by fast speed and can meet the technological requirements of mass production. The disadvantage is that the adhesive product is prone to bubbles, easy to whiten, and has poor weather resistance, which directly affects the appearance and product quality of plexiglass products. Therefore, how to choose a suitable adhesive to improve the grade and grade of plexiglass products is a major problem that must be solved first in the bonding process.

In addition, bonding skills are also very important. The following are some common bonding techniques, a brief analysis of their practical experience.

1. Docking: Place the two plexiglass plates to be docked horizontally on the operating platform, close them, and sticky tape on the bottom, leaving a gap not greater than 0.3mm wide for applying adhesive. Use a syringe to inject the adhesive uniformly and slowly through the gap from one side until it is completely filled. After it is completely cured, remove the tape.

2. Facade laminating: Facing laminating is the most widely used laminating technology, widely used in the production of various plexiglass IT electronic digital display products. First, the surface to be bonded must be wiped clean. It is best to use a die to achieve the bonding, so that the bonded object will not shake, which is beneficial to improve the bonding quality. For the bonding of plexiglass plates with a thickness of 3mm, thin metal wires can be inserted, and the bonding can be completed by capillary action. The metal wires can be drawn out before the adhesive is cured, or the adhesive can be applied after bonding with tape.

3. Bevel bonding: The bonding bevel must use a 90-degree angle to prevent the bonding surface from shifting. Apply the adhesive slowly and evenly. The master can only be removed after it is completely cured.

4. Plane bonding: Plane bonding is a special bonding method. First, wipe the glued surface clean, place it horizontally, and pour an appropriate amount of adhesive on it. Place the other plexiglass plate on one side obliquely, contact with the plexiglass plate coated with adhesive, and then put it down evenly and slowly to drive out air bubbles from one side to complete the bonding. The plexiglass adhesive will corrode the surface of the plexiglass board, leaving traces that are difficult to eliminate. Therefore, the tape can be used to protect parts that do not need to be glued. Grease, dust, or pores can hinder the uniform application of the adhesive and leave air bubbles. When the adhesive shrinks, excessive use of the adhesive will bring in air. Direct blowing will cause the edge of the bonding surface to become white due to the volatilization of the adhesive. Indoor humidity, temperature, etc. It has a direct impact on the adhesion of plexiglass.

The acrylic sheet manufacturer tells you that a very critical process in the acrylic sheet solution process is the bonding process of the acrylic sheet. The bonding process also requires perseverance. Products can be displayed to attract customers’ attention. Therefore, the acrylic board manufacturers remind you to pay attention to the matters that should be paid attention to when bonding the acrylic board to produce and process products:

1. If the acrylic product is blown immediately, the edges of the adhesive will become milky white due to the rapid evaporation of the adhesive.

2. Before the adhesive is cured, the acrylic emulsion will have varying degrees of yellow when exposed to the sun for a long time, which greatly impairs the aesthetics of the acrylic emulsion.

3. This type of adhesive will rot the name of the acrylic production and processing product, leaving an imprint that cannot be removed, so it is possible to use an adhesive-free method to maintain the whole machine without bonding.

4. Acrylic board products must be connected beforehand. Due to vegetable oils, dust, or holes, the adhesive of the uniform coating layer will be prevented from remaining blisters.

5. If the amount of adhesive is too small, air will be drawn in when the adhesive shrinks.

The above five points are all matters needing attention in the production and processing of acrylic sheets. Only with careful processing technology, the products can meet the needs of customers.
