in What are the requirements for material selection during the processing of acrylic products ? Let us introduce the various glasses.

glass:

1, ordinary glass:

Turquoise green, fragile, low transparency, easy to age and deform in rainy days and sunlight, try not to be used as a fish tank.

2, float glass:

Transparent float glass is made from glass paste through a control door into a tin bath. Due to the action of gravity and surface tension, it floats on the surface of the molten tin and then enters the cold bath to make both sides of the glass smooth and uniform, and the ripple disappears. Dark green, smooth surface without ripples, good perspective, and a certain degree of toughness. Recommended Use.

3. Tempered glass:

Tempered glass is a high-strength safety glass that is heated to a softening point and then cooled by a large amount of air. At the same thickness, the flexural strength of tempered glass is 4-5 times higher than that of ordinary glass, and the impact strength is 5 times higher than that of ordinary glass. Tempered glass has a strong thermal stability and can withstand severe temperature changes without damage. The larger feature of tempered glass is safety. This kind of glass can be broken into honeycomb particles to avoid harm to the human body. Note: Tempered glass can no longer be cut, drilled or grooved. It is not recommended for use in aquariums because the glass breaks into honeycomb particles and cannot be repaired at all.

4, acrylic glass

A glass material similar to plexiglass and ordinary glass was originally used in aircraft. Most of the early curved acrylic fish tanks were made of acrylic glass. It is light in weight and strong in toughness. It needs a body. It is easy to scratch and has low transparency.

5, plexiglass

PMMA, commonly known as plexiglass, is an important thermoplastic developed earlier. It has good transparency, chemical stability, easy dyeing and processing. However, the strength is low, except for some small process tanks (boxes) that are usually not used.

Glass glue:

Silicone glass glue is the full name. There are a variety of glass glues on the market, such as acid glass glue, neutral weathering glue, silicate neutral structure glue, silica glue, neutral mold glue, hollow glass glue, aluminum plastic plate special glue, aquarium special glue, Large glass special glue, bathroom special anti-corrosive glue, acid structural glue, etc.

Special glues for aquariums are generally rare, so please use imported glue, and then use high-quality glass glue.

Manufacturing Technology

Grinding (car) surface:

Polish the edges of the cut glass to the right size to make it smooth, beautiful and not dangerous. With a special glass edging machine, the cut glass is generally subjected to 45 degree chamfering.

Tensile:

In order to prevent the cylinder block from leaking or rupturing due to water pressure after water injection, the local edge reinforcement method is also adopted, which is also made of glass material, and is generally used for the upper and lower edges of the cylinder block.
