The advantages and disadvantages of acrylic aquariums and ultra-white glass?


First, the advantages and disadvantages of ultra-white glass fish tank:
1. The glass self-explosion rate is low because the ultra-white glass raw materials generally contain less impurities such as NiS, and the fine control during the raw material melting process makes the ultra-white glass have a more uniform composition than ordinary glass, and its internal impurities are less, which greatly reduces the possibility of self-explosion after tempering.
2. Color consistency Because the iron content in the raw material is only 1/10 or even lower than that of ordinary glass, ultra-white glass absorbs less green band in visible light than ordinary glass, ensuring the consistency of glass color.
3. The visible light transmittance is high, the permeability is better than 91.5% of the visible light transmittance, with crystal clear crystal quality, so that the display products are more clear, more able to highlight the true appearance of the exhibits.
4. Low ultraviolet transmittance Compared with ordinary glass, ultra-white glass has a lower absorption of the ultraviolet band, which can be used in places that prevent ultraviolet rays, such as museums and other areas, which can effectively reduce the passage of ultraviolet rays, slow down the fading and aging of various exhibits in the display cases, especially the protection of cultural relics.
5. Large market, high technical content, and strong profitability Ultra-white glass technology content is relatively high, production control is difficult, and has relatively strong profitability of ordinary glass. The high quality determines its high price, the current price of ultra-white glass is 1 to 2 times that of ordinary glass, the cost is not much higher than ordinary glass, but the technical barriers are relatively high, with high added value.
Then say the advantages and disadvantages of acrylic fish tank:
Advantages: It has the characteristics of light weight, good light transmission, strong plasticity, and not easy to break.
1. Easy to scratch, not only as the outside of the aquarium, internal cleaning will not be like a glass aquarium can use a algae scraper to clean the algae on the aquarium wall, leaving subtle traces on the tank wall. These marks can not be repaired, and remain on the cylinder wall for a long time, more and more, seriously affecting the ornamental.
2. Aging faster than glass. It yellows easily. Aging is another unacceptable defect. Acrylic is a kind of plexiglass, and the essential difference between it and ordinary glass is mainly reflected in the material. The aging speed of acrylic is much faster than that of general glass, and the aging acrylic glass is yellow and brittle. Brittle means easy to crack. So cracking is the third defect, especially in large fish tanks.
3. Acrylic is originally corrosion resistant, but water and alkali will accumulate on the cylinder wall at the water surface, forming a piece of white plaque. If you choose the sea tank, this phenomenon is more obvious. So the question is, without scratching the cylinder wall, how do you plan to remove frequent water alkali?
4. Easy to deform. Acrylic has strong plasticity and is the main material for hot bending cylinder. But for this reason, it is also prone to deformation. If it is not strained, it may appear deformed after a few years. But you'd have to make sure you've been using the same fish tank for years to get that problem.
