The acrylic bonding method of acrylic swimming pool
The bonding of acrylic swimming pools is a key process link in acrylic processing. How to show the clear and transparent characteristics of plexiglass, the sense of the value of acrylic swimming pools, and how to improve the grade and taste of acrylic handicrafts, bonding technology plays an important role.
The bonding of plexiglass is mainly affected by two aspects: one is the applicability of the adhesive itself; the other is the bonding skills.
There are many adhesives at home and abroad, there are two main ones, one is two-component, such as all-purpose adhesive and epoxy resin, and there are also single-component, such as CHCl3. Generally speaking, two-component adhesives are produced by curing reaction Bonding, while one-component adhesives are bonded by solvent evaporation.
The two-component adhesive is characterized by a good bonding effect, no foaming, no whitening, and high strength after bonding. The disadvantage is that the operation is complicated and difficult, the curing time is long, the speed is slow, and it is difficult to meet the requirements of mass production. The general one-component adhesive is characterized by fast speed, which can meet the process requirements of mass production. The disadvantage is that the bonded product is prone to foaming, whitening, and poor weather resistance, which directly affects the appearance and product quality of plexiglass products. Therefore, how to choose a suitable adhesive and improve the grade of plexiglass products is a big problem that must be solved first in the bonding process.
In addition, the bonding skills of the acrylic swimming pool are also very important. Introduce some common bonding techniques for acrylic swimming pools, and briefly analyze their practical experience.
1. Docking: Place the two plexiglass plates to be butted on the operating platform horizontally, close them, stick tape on the bottom, and leave a gap no larger than 0.3mm wide for gluing. Use a syringe to inject the adhesive into the gap evenly and slowly from one side until it is completely filled. After it is completely cured, remove the tape.
2. Facade bonding: Facade bonding is a widely used bonding technology, which is widely used in the production of various plexiglass IT electronic digital display products. First, the surface to be bonded should be wiped clean. Use a mold to achieve bonding, so that the glue will not shake, which is conducive to improving the bonding quality. For the bonding of plexiglass plates with a thickness of 3mm, fine metal wires can be placed on them, and the bonding can be completed by capillary action. The wire is pulled out, and it can also be glued with tape, and then the adhesive is applied.
3. Oblique bonding: A 90-degree template must be used to bond the inclined surface to prevent the bonding surface from shifting. Apply the adhesive evenly and slowly, only remove the contours when fully cured.
4. Flat bonding: Flat bonding is a special bonding method. First, wipe the glued surface clean, place it horizontally, pour an appropriate amount of glue on it, place another plexiglass plate at an angle, contact with the plexiglass plate coated with the adhesive, and then put it down evenly and slowly, removing the air bubbles from one side. Driven out to complete the bond, the plexiglass adhesive will corrode the plexiglass surface, leaving indelible marks. Therefore, the tape can be used to protect parts that do not need bonding, where grease, dust, or air holes can prevent the adhesive from spreading evenly and leaving air bubbles behind. Excessive use of adhesive can introduce air as the adhesive shrinks. Direct blowing will make the edge of the glue surface white due to the volatilization of the glue, and the indoor humidity and temperature will have a direct impact on the bonding of plexiglass.
Acrylic swimming pool cleaning and maintenance precautions
1. Precautions for the maintenance of acrylic swimming pools.
1. Do not wipe the swimming pool with cleaning powder, it will corrode the surface and reduce the brightness.
2. It is strictly forbidden to wipe the swimming pool surface with sharp objects or abrasive objects.
3. After the swimming pool is installed under the water, the silica gel needs 24 hours to cure, generally do not use it during this time, otherwise it will cause water leakage.
4. It is strictly forbidden to place light bulbs, open flames, and high-temperature objects connected to the power supply in the swimming pool, otherwise, it will leave traces or cause the swimming pool to deform.
5. Avoid contact with strong organic solvents such as paint, volatile agents, thinners, etc., otherwise, it may cause surface softening, dissolution, cracking, and other phenomena that endanger product quality.
6. It is forbidden to add boiling water directly into the swimming pool. When swimming, add cold water before heating. Acrylic products begin to soften when heated at 100°C, so avoid storage and use at high temperatures above 60°C.
7. Strictly use highly corrosive chemical liquids (such as sulfuric acid, hydrochloric acid, and lye) to wipe. The surface of the pool body and hardware accessories shall not be disinfected with strong corrosive disinfectants such as 84 disinfectant. Disinfection supplies can be disinfected with special disinfectants for baby pools or other physical disinfection methods.
Second, acrylic swimming pool cleaning precautions
1. When cleaning the acrylic swimming pool every week, use a sponge or flannel, do not use coarse cloth or scouring pad, do not use any cleaning agent containing granular objects, and avoid direct sunlight and high-temperature contact. After each water change in the children’s pool, rinse thoroughly with clean water and dry with a soft cloth. When cleaning, use mild detergent, do not use abrasive detergent, or use glass water to wash.
2. Repair traces in time. Do not hit or hit the pool surface with hard objects, causing scratches or bruises. If scratches appear accidentally, you can sand them with 2000c water sandpaper, then use toothpaste and a soft cloth.
3. Deal with pipe blockages at any time, use special pipe cleaners, and disinfect the sewer pipes on time. It is recommended to wash it once or twice a month to remove the smell and prevent the growth of bacteria.
