Take you to understand the material characteristics of acrylic swimming pools
The acrylic swimming pool is a special place for people to swim, where they can play or compete, most swimming pools are built on the ground, according to the water temperature can be divided into ordinary swimming pools and thermostatic swimming pools, which can be divided into indoor and outdoor, the official pool is 50 meters long, at least 21 meters wide and more than 1.8 meters deep; swimming, diving, water polo pools, water depth of 1.3 ~ 3.5 meters; 10-meter diving pool, the water depth to 5 m, the pool water temperature should be maintained at 27 ~ 28. There should be filtration and disinfection equipment to keep the pool water clean.
Acrylic swimming pool material acrylic also known as PMMA or plexiglass, chemically named polymethyl methacrylate, is an important plastic polymer material developed earlier, with good transparency, chemical stability, and weather resistance, easy to dye, easy processing, beautiful appearance, widely used in the construction industry. Plexiglass products can usually be divided into cast panels, extruded panels, and molded plastics.
Acrylic swimming pool material characteristics.
1. With crystal transparency, a light transmission rate of 92% or more, soft light, visual clarity, and coloring with dye acrylic coloring effect is good.
2. Acrylic panels have excellent weather resistance, high surface hardness, good gloss, and high-temperature performance.
3. Acrylic panels have good processing performance, both thermoforming, but also mechanical processing.
4. Transparent acrylic sheet light transmission is comparable to glass, but the density is only half that of glass. And it is not as fragile as glass, and even if broken will not form sharp fragments like glass.
5. Acrylic plate wear resistance close to aluminum, good stability, and resistance to a variety of chemicals.
6. Acrylic panels have good printability and spraying performance, the appropriate printing and spraying process can give acrylic products ideal surface decorative effects.
7. Combustibility: non-spontaneous combustion, combustible, not self-extinguishing.
Acrylic swimming pool material characteristics.
1. Hardness. Hardness is one of the parameters that can reflect the production process and technology of cast acrylic panels and is an important part of quality control. Hardness can reflect the purity of the raw material PMMA, the sheet’s weather ability, and high-temperature resistance. Hardness directly affects whether the sheet will shrink and bend during processing and whether the surface will crack. Hardness is one of the hard indicators to measure the quality of the acrylic sheet.
2. Thickness (acrylic tolerance). Acrylic tolerance exists in the thickness of the plate, so the control of acrylic tolerance is an important reflection of quality management and production technology.
3. Transparency/whiteness. Strict selection of raw materials, advanced formula follow-up, modern production process, to ensure the excellent transparency and pure white of the plate, flame polishing, crystal clear.
Take you to understand the acrylic swimming pool acrylic bonding method
Acrylic swimming pool bonding is a key process link in acrylic processing. How to show the clear and transparent characteristics of plexiglass, acrylic swimming pools’ sense of value, to enhance the grade and taste of acrylic crafts, bonding technology plays an important role.
Plexiglass bonding is mainly affected by two aspects: one is the suitability of the adhesive itself; the second is the skill of bonding.
There are many adhesives at home and abroad, there are mainly two kinds, one is two-component, such as universal adhesive and epoxy resin, and there are also single-component, such as CHCl3. Generally speaking, the two-component adhesive is bonded by a curing reaction, while the single-component adhesive is bonded by solvent volatilization.
The characteristics of a two-component adhesive are a good bonding effect, no blistering, no whitening, and high strength after bonding. The disadvantage is that the operation is complicated, difficult, long curing time, slow, and difficult to meet the requirements of mass production. The general one-component adhesive is characterized by fast speed and can meet the requirements of the mass production process. The disadvantage is that the bonded products are easy to blister, white, poor weather resistance, which directly affects the appearance of plexiglass products and product quality. Therefore, how to choose the right adhesive to improve the grade and class of plexiglass products, is the big problem that must be solved first in the bonding process.
In addition, the bonding skills of acrylic swimming pools are also important. Introduce some common bonding techniques for acrylic swimming pools and a brief analysis of their practical experience.
1. Docking: the two pieces of plexiglass panels are to be docked horizontally on the operating platform, closed, and the bottom of the tape, leaving a gap no greater than 0.3mm wide for the application of adhesive. Use a syringe to inject the adhesive evenly and slowly into the gap from one side until it is completely filled, and then remove the tape after it is completely cured.
2. Elevation bonding: elevation bonding is a widely used bonding technique, widely used to make various Plexiglas IT electronic digital display products, first of all, the surface to be bonded should be wiped clean. Use the mold to achieve bonding, so that the adhesive will not shake, which is conducive to improving the quality of bonding, for the bonding of a 3mm thick plexiglass plate, you can pad the fine metal wire, through the capillary action to complete the bonding, you can pull out the wire before the adhesive curing, you can also use adhesive tape bonding, and then apply adhesive.
3. Oblique bonding: 90-degree template must be used to bond the oblique surface to prevent the bonding surface from shifting. Apply the adhesive evenly and slowly, and remove the profile only after it is completely cured.
4. Planar bonding: Planar bonding is a special bonding method. First, wipe the bonded surface clean, place it horizontally, pour the right amount of adhesive on it, place the other Plexiglas board on one side at an angle, contact with the Plexiglas board coated with adhesive, and then put it down evenly and slowly to drive out the air bubbles from one side to finish the bonding, the Plexiglas adhesive will corrode the Plexiglas surface and leave indelible traces. Therefore, adhesive tape can be used to protect the parts that do not need to be bonded. Grease, dust, or air pockets can prevent even coating of the adhesive and leave air bubbles. Excessive use of adhesive can bring in the air as the adhesive shrinks. Direct blowing will make the edges of the adhesive surface white due to the volatilization of the adhesive. Indoor humidity and temperature have a direct impact on the bonding of Plexiglas.
Acrylic swimming pool engineering design, installation, and maintenance
Today, talk about the construction program of the acrylic swimming pool project, including the use of the acrylic swimming pool initial research design, acrylic swimming pool installation technology, and acrylic swimming pool later for maintenance.
At the beginning of the project cooperate with the customer, provide the customer with a detailed construction plan and quotation program, and according to the actual situation of the customer project survey to confirm. Generally include: project overview, construction process flow, progress plan, site coordination, post-maintenance, and other items, combined with the construction of the project, a detailed understanding of the process;
I. Construction process
