Someone left a message saying that plexiglass is durable and transparent, which is more suitable for greenhouse. Let's not draw a conclusion first. Let's make a comprehensive comparison first, and you will know which one is better.
The chemical name of plexiglass is polymethyl methacrylate, which is a macromolecular compound polymerized by methyl methacrylate and is an early developed thermoplastic.
Organic glass is divided into colorless transparent, colored transparent, pearlescent and relief organic glass. Its shortcomings are also its fatal weakness: fragile, difficult to make thick products, can not make hollow products. Moreover, the surface is not easy to take care of and is prone to water stains. Organic glass products have poor temperature resistance and are easy to burst due to temperature changes. Of course, the transparency of plexiglass is good.It has strong fashion, rich shape and wide application.
Let's take a look at the sunshine board (PC board). First of all, the raw material of sunshine board is PC polycarbonate, which is generally a double-layer structure, and the thickness of more than 10 mm is a multi-layer special-shaped structure with high light transmittance. Cold and heat resistance: between -40 and 120, the sunlight board will not be deformed. The self-ignition point is 580, which can be extinguished automatically after ignition. When burning, it will not produce toxic gases, nor will it contribute to the spread of fire.
We compare the flame retardancy of the two products. Plexiglass is PMMA, commonly known as acrylic. It does not spontaneously combust, but is flammable and not self-extinguishing. The average hardness is about 8 or 9 degrees on the Rockwell scale. Heat resistance is not high, continuous use temperature over 90 will be thermal deformation. The cold resistance is also poor, and the crisp temperature is about 9.2.
Moreover, the sunlight board is generally hollow, and the plexiglass is solid. One side of the sunlight board is anti-condensation, and the other side is anti-ultraviolet. The plexiglass is the same on both sides. Sunlight panels can be exposed directly outdoors, while plexiglass generally cannot receive direct sunlight. The sunlight board has good light transmission performance, strong impact resistance and excellent heat preservation performance.
To sum up, sunshine board is more suitable for roof than plexiglass, and it is also an excellent material for sunshine greenhouse.
