Acrylic fish tank is a high-grade aquarium product. Acrylic has a high transparency and a light transmittance of 92%. It has the reputation of "plastic crystal". It has better weather resistance, especially for outdoor use, it is the crown of other plastics, and has good surface hardness and luster, and has large processing plasticity. Acrylic can be made into a variety of shapes and products. Another variety of plates, rich in color (including translucent swatches), another characteristic of acrylic is that the slab can still maintain high transparency. Acrylic fish tanks have good weatherability and acid and alkali resistance.

Pay attention to the surface of the aquarium with scratches, scratches, no nodular vortex, surface shrinkage marks (especially at the corners), cracks, mottled spots, mildew spots, alkali marks, water marks, bubbles in the middle of the plate, and foreign objects. Impurities. The glass aquarium has high transparency, is not easy to scratch, and has high pressure resistance. The glass aquarium is made of silica gel. The safety of the glue depends on whether the thickness of the glue is uniform and whether there is air bubbles in the glue.

1. Acrylic contains a polar side methyl group, which has obvious hygroscopicity. The water absorption rate is generally 0.3%-0.4%. It must be dried before molding. The drying condition is drying at 80°C-85°C for 4-5h.

2. Acrylic has obvious non-Newtonian fluid properties in the temperature range of molding processing. The melt viscosity decreases with the increase of shear rate, and the melt viscosity is also sensitive to temperature changes. Therefore, for the molding process of acrylic, increasing the molding pressure and temperature can significantly reduce the melt viscosity and achieve better fluidity.

3. Acrylic begins to flow at a temperature of about 160 ° C, and the temperature at which decomposition begins is higher than 270 ° C, with a wide processing temperature range.

4. Acrylic melt viscosity is higher, the cooling rate is faster, and the product is easy to generate internal stress. Therefore, the process conditions are strictly controlled during molding, and post-treatment is also required after the product is formed.

5, Acrylic is an amorphous polymer, the shrinkage rate and its range of variation are small, generally about 0.5% -0.8%, which is conducive to the formation of plastic parts with higher dimensional accuracy.

6. Acrylic cutting performance is very good, and its profiles can be easily machined to various required sizes.
