Bending radius of monolithic and cellular polycarbonate
Polycarbonate is one of the most popular materials for construction. application for the equipment of greenhouse complexes, and in the manufacture of carports, and even when installing canopies. It features incredibly high strength, excellent light transmission and long service life.
Moreover, it is also a flexible material, however, when installing an arched roof, it is necessary to take into account the bending radius of cellular polycarbonate (or monolithic, if we are talking about it).
It is possible to bend monolithic polycarbonate, because this type of plastic (polymer) has a large number of positive parameters and properties:
- Relatively light weight.
- High degree of flexibility.
- Wide operating temperature range (-40 ...
+ 125 degrees).
- High quality sound insulation.
- Amenable to curvature both in cold and hot conditions.
- Easy to handle.
- Does not chip if the integrity of the surface is violated.
Monolithic slabs (as opposed to the same glass) are significantly higher in strength. The thickness of one sheet is from 0.2 to 2 cm. If you compare it with a honeycomb, then the weight of the monolith will be heavier, and it will cost more. Most often it is used to equip urban infrastructure.
Honeycomb-type plastic sheets are thinner, and their thickness can be from 1.6 to 4.2 cm, and they also stand out from the rest in terms of thermal and noise insulation, excellent transparency. Given the fact that much less of the required raw materials are consumed for its manufacture, the initial cost is low. Due to such quality, transparent honeycomb plastic is actively used to create overlapping greenhouses, sheds and greenhouses.
This concept means that an indicator that will indicate the maximum allowable value of sheet folding. If you ignore this parameter when installing an arched roof, you may have such negative consequences when using slabs with a smaller radius than required:
Please note that the quality of the twist will not be reflected in any way on the strength and shape characteristics of the resin plastic.
After the process of unrolling the roll, the polycarbonate will take on its original appearance.
When creating honeycomb plastic sheets, the manufacturer complies with certain standards. So, the usual dimensions of a cellular polymer are 210 * 600 or 210 * 1200 cm, and a monolithic 205 * 305 cm. An interesting fact is that cast and honeycomb sheets differ in terms of the minimum degree of curvature, and also in the weight and thickness of the sheets. The thinner the material of synthetic origin is, the more it will bend (or curl).
It is possible to bend monolithic polycarbonate in all directions - both along and across.
Please note that it is allowed to twist the sheets of polymeric cellular plastic only along the stiffeners. Moreover, when installing transparent boards, it is important to consider where the UV-coated side is located, since otherwise the material will not fully perform its functions.
To avoid damage to the synthetic panels during transport, you must never exceed the restrictive barrier when curling the material. Otherwise, the probability that the polymer will burst is almost 90%.
The following indicators are obtained:
75 meters (transportation can be carried out either on the roof of a car or by a truck).
By and large, in terms of the curvature parameters of monolithic and cellular polymer, the indicators are practically similar, but the cast-type plastic twists better in all directions. But in terms of mass, it loses to hollow material, which will impose certain restrictions when used in certain structures and structures.
One of the advantages of polymer type plastic is the ability to bend even in a cold state, and therefore there is no need to expose it to a certain temperature level, which greatly simplifies the work with it. Here the most important condition is to take into account the indicator of the minimum degree of curvature.
Since molded plastic bends in all directions, there were no particular difficulties in giving it the required shape.The process of bending slabs of a monolithic type provides for the following algorithm:
This way you can roll the molded type of plastic to the required degree, but without exceeding the permissible value. Despite the fact that this type of building material has an increased level of strength, compliance with safety measures will still not be superfluous.
To give a specific shape for a sheet, it is necessary to take into account the following important points:
It is not effective to heat cellular building materials, and it is best to use monolithic slabs for plastic bent at a right angle. The rate of flow of synthetic material is extremely important, since it is more than +125 degrees. To bend cellular or monolithic polycarbonate at home, it is imperative to adhere to the instructions, and also not to overdo it with the force of curvature.
Polymer plastic is a universal building material that has a large number of positive parameters, one of which is the ability to bend in a cold state ... The main thing here is not to exceed the permissible value of the minimum twisting degree for a certain thickness of the slabs. When using cellular plastic of a polymer type, it is important to bend only along the honeycomb.
The permissible bending radius of monolithic polycarbonate is a special value of a synthetic building material, which must be taken into account when giving the slab the desired shape. It is quite easy to do it at home - with your hands, clamping the stove in a vice. Compliance with the main recommendations makes it possible to achieve the desired result.
