① Highly transparent. Plexiglass is currently the most excellent polymer transparent material, with a light transmittance of 92%, which is higher than that of glass. The tube of the sun lamp called the artificial little sun is made of quartz because quartz can completely transmit ultraviolet rays. Ordinary glass can only transmit 0.6% of ultraviolet rays, but plexiglass can transmit 73%.
②High mechanical strength. The relative molecular mass of plexiglass is about 2 million. It is a long-chain polymer compound, and the chains that form the molecules are very soft. Therefore, the strength of plexiglass is relatively high, and the ability of tensile and impact resistance is higher than that of ordinary glass. 18 times. There is a kind of plexiglass that has been heated and stretched, in which the molecular chains are arranged in a very orderly manner, which significantly improves the toughness of the material. Use nails to penetrate this plexiglass, even if the nail penetrates, there will be no cracks on the plexiglass. This kind of plexiglass will not break into pieces after being penetrated by a bullet. Therefore, the stretched plexiglass can be used as bulletproof glass, and also as a cockpit cover on an airplane.
③Light weight. The density of plexiglass is 1.18kg/dm. The weight of a material of the same size is only half that of ordinary glass, and 43% of metallic aluminum (belonging to light metal).
④Easy to process. Plexiglass can not only be cut with a lathe and drilled with a drill, but also can be bonded into various shapes with acetone, chloroform, etc., and can also be processed into airplanes by blow molding, injection, extrusion, and other plastic molding methods. Cockpit covers are as small as dentures and dental trays.
Where are the advantages of ocean engineering technology?

Therefore, after promotion in the market, the advantages it occupies will become more and more prominent. So, where are the technical advantages of aquarium marine engineering reflected?
However, when comparing the technical advantages of aquarium marine engineering manufacturers, it is also necessary to understand the process flow in the molding process. Only in this way can we know that the efficiency and performance of the molding equipment in the operation process are also very prominent. Improve the marketing characteristics in the market.
Fish farming and water quality
Higher acidity will affect the growth rate of the fish, and it is ideal to keep the pH at 6.8-7 degrees.
Too low water temperature will affect the fish’s metabolism, it is better to keep it at 26-28 degrees Celsius.
Ammonia and nitrite
During the breeding process, due to residual bait, fish metabolism and organic matter corruption, the concentration of ammonia (also known as Armonia) and nitrite in the water will gradually increase, becoming the number one killer of fish. Moreover, ammonia can destroy the function of red blood cells in fish, causing serious physiological damage.
Ammonia and nitrite poisoning symptoms:
1, difficulty breathing;
2, the eyes are cloudy;
3. Difficulty in swimming and loss of balance;
4. In severe cases, lying on the bottom of the tank, even death.
The detection of ammonia and nitrite relies on various test tools sold in the aquarium market.
Ammonia and nitrite concentration index:
Water quality range Ammonia (Ammonia) Nitrite (Nitrite)
Ideal water quality 0mg/L 0.3mg/L
Short-term tolerable range 0.25mg/L 0.8mg/L
Danger 1.5mg/L 1.6mg/L
Very dangerous 5mg/L 3.3mg/L
PH requirements for several types of common ornamental fish:

The maintenance of the acrylic fish tank
Acrylic fish tanks are one of the mainstream fish tanks today, so many consumers who like to raise fish in the family want to know how acrylic fish tanks are and how to maintain them. Today, I will follow the editor to take a look at the characteristics of acrylic fish tanks and acrylic fish tanks. Purchase skills and maintenance skills for your reference.
1. Acrylic Fish Tank–Features
1. Acrylic fish tank has good weather resistance and acid and alkali resistance.
2. Acrylic fish tank has excellent insulation performance.
3. Acrylic fish tank has good light transmittance, which can reach more than 92%, and the required light intensity is small, which saves electricity.
4. Acrylic fish tank has strong impact resistance, which is sixteen times that of ordinary glass.
5. Acrylic fish tanks have a long lifespan, which is more than three years longer than fish tanks of other materials.
6.Acrylic has lightweight, half lighter than ordinary glass, and the load on buildings and brackets is small.
7. Acrylic fish tanks are colorful and high-brightness, which can’t be matched by other materials.
8. Acrylic fish tank has strong plasticity, large changes in shape, and easy processing and forming.
9. Convenient maintenance, easy to clean, rain can be cleaned naturally or scrubbed with soap and a soft cloth.
10.Acrylic sheet has excellent weather resistance, high nominal softness and surface gloss, and poor low-temperature performance.
11.The wear resistance of acrylic sheet is on the verge of aluminum, and it is not regularly resistant to the corrosion of a variety of chemical teachings.
Acrylic fish tanks are made of special materials like acrylic. This material is light and environmentally friendly, and the landscape is also very beautiful, which is deeply loved by people. But in daily fish farming, the daily care of acrylic fish tanks is also an issue that needs our attention:
1. Acrylic is a new type of plastic material with good transparency and weather resistance. However, acrylic is easily corroded by some solvents. After the acrylic is corroded, it is likely to produce cracks that affect its appearance. In our daily life, we should avoid contacting acrylic fish tanks with some quick-drying diluents, aromatic hydrocarbon solvents, esters such as ethyl acetate, and ketone solvents such as acetone. These solvents are corrosive, and Acrylic fish tank contact will erode the fish tank. Some paints, adhesives, various primers, etc. almost contain toluene. These solvents will also corrode acrylic fish tanks, so avoid direct contact with acrylic fish tanks. In addition, these solvents also have a certain degree of volatility, and the volatilized gas will also corrode acrylic after contact with acrylic, so don’t talk about these things being put together with acrylic.
2. Acrylic is easily deformed when the temperature is above 100°C, so do not put acrylic in an environment with a temperature above 80°C, which may cause acrylic deformation. Do not put acrylic in an environment where there are many sparks in electric welding. Some cigarette butts will also cause acrylic deformation. Try not to throw cigarette butts around the acrylic. Avoid prolonged exposure of acrylic to lighting or spotlights.
3. If the acrylic fish tank is used for a long time, there will be some dust or oil on the surface of the fish tank. The way to clean the dust and oil is to wipe it gently with a soft cloth or sponge. For some difficult-to-remove stains such as oil stains, it is recommended to wipe slowly with warm water. When cleaning solvents such as detergent are necessary, make sure in advance that there is no solvent in the cleaning agent that will corrode the acrylic fish tank.
4. Sometimes there will be some difficult-to-remove stains on the acrylic surface, such as adhesive tape, which will cause damage to the acrylic surface when cleaning with some solvents, so don’t use it.
How to maintain fish tank acrylic sheet
When designing interior decoration, many aquarists will put an ornamental fish tank in the living room, not only to increase the beauty of the living room, but also to cultivate sentiment in the free time, but the acrylic plate material of the ornamental fish tank should be maintained with reasonable maintenance. Do you know how to do it? I will introduce the tips of ornamental fish tank maintenance to all aquarists, and what are the advantages of using ornamental fish tanks. Four tips for the maintenance of ornamental fish tanks. In normal times, if you find that there is dust on the fish tank, you can use a feather duster, or wipe it with a rag moistened with clean water.
If you want to keep the acrylic sheet of the ornamental fish tank always bright, you can use liquid polishing wax. The steps are: choose a soft cloth, pour the polishing wax on it, and then evenly scrub it on the fish tank to maintain the brightness of the acrylic sheet. degree. If you accidentally watch the fish tank with a chipped corner, don’t panic at this time. You can use IPS adhesive glue to apply to the damaged position, and then glue the piece that fell off, and wait for it to dry.
Uses of fish tank filters
Its purpose is:
1. In order to remove feces and other dirt in the water.
2. In order to keep the water clear, with sufficient oxygen, no harmful substances, and no pollution, create a comfortable environment suitable for the growth of fish.
How the fish tank filter works
As a fish tank filter, there must be two or more filtering methods. At present, the main filtering methods are physical filtration, biochemical filtration, chemical filtration, adsorption filtration, and it will work continuously as long as it is plugged in. Below, I will follow up and introduce the principles of various filtering methods.
Physical filtration: It uses mechanical means to isolate the larger particles in the water.
Biological filtration: cultivating beneficial bacteria and decomposing harmful elements through bacteria, such as ammonia, nitrite, nitrate, phosphate, etc. Commonly used filter materials are: biochemical balls, ceramic rings, glass rings, coral sand, etc. (the main filter method is to maintain the ecosystem)
Chemical filtration: It is the use of chemical agents to remove impurities in water. The agents used include water stabilizers, flocculants, algaecides, protein decomposers, deodorants, and so on.
Adsorption filtration: It is wood, coal, fruit shells, animal bones, and other substances with an extremely high carbon content that can absorb proteins, trace elements, decolor and deodorize in seawater, and even ozone molecules can be absorbed by it. Fish urine, microalgae, and drugs in the water can also be absorbed by it. Because nitrifying bacteria must live in the filter cotton, glass ring, or bottom sand with flowing water, the filter should be opened 24 hours a day.
Filtration equipment is very important for fish tanks. A suitable filter can reduce the number of water changes in the fish tank, and at the same time provide a good water quality environment for the fish; if you have other questions about the fish tank filter, you can be better with nature Aquarium gets in touch to solve related problems such as filtration for you.
