In the ancient culture of China, derived from a variety of national culture, during which there are many amazing art forms born, of course, there is no shortage of a variety of cruel punishment, let people shudder, but in today's democratic society, human rights first, for such inhumane punishment we do not advocate ......
But you know what? In Sayyas' window and door laboratory, the main materials of the brand's own window and door products are still subjected to "hellish torture", which is a must for every successful window to go through the ordeal!
External aluminum panel frame - Baig test and cooking
For aluminum clad wood windows, its life is always made up of two sides, the inner side is made up of solid wood to provide a softer and more comfortable environment inside. The outer side is made up of an aluminum frame that must withstand the wind, rain, sun, etc. on a daily basis, thus protecting the interior.
Therefore, for the outer aluminum frame, its birth will be a very "cruel" process. Regarding the adhesion of the aluminum powder, in Sayyas window and door laboratory, a hundred frames will be drawn with a scribe to observe whether there is paint loss, peeling and other phenomena, as if the aluminum surface is cut numerous times with a knife.
After the 100-gram test, the outer aluminum frame will also be impacted by the impact table, and then repeatedly sticky uncovered using special 3M tape imported from the United States, the results require: naked eye observation, the coating does not appear peeling, chipping phenomenon.
After passing the above two tests, the outer aluminum frame will also be put into boiling water for two hours, requiring no bubbles, no peeling, no discoloration.
After this "torture", if the outer aluminum frame can maintain its standard, then it has the qualification to become part of Sayyas aluminum clad wood windows, to ensure that the outer aluminum powder in the process of use, hard objects cut, strong impact, rain soaked, etc. will not appear in the phenomenon of paint, fading.
Glass - smash test
Glass accounts for more than 75% of the entire window area, its importance is evident, so in Sayyas windows and doors laboratory, it is also difficult to escape the fate of "torture". During the experiment, the experimenter will use a steel ball with a weight of 1040g to impact the surface of the tempered glass at a height of 1m, and the tempered glass will be qualified if it is not damaged (6 specimens, all of which will not be damaged).
Tempered glass hardness is one of its advantages, we will not let it break, but the glass is fragile after all, even if the tempered glass will inevitably break, in the laboratory, tempered glass will also be "cruel" broken, the purpose is to verify whether the granularity of the broken tempered glass to meet the safety performance standards (The more granularity, the safer).
National standard requirements: the number of fragments in the range of 50 * 50 mm ≥ 40, allowing a small number of long fragments, its length does not exceed 75 mm.
Sayyas requirements: the number of fragments in the range of 50 * 50 mm ≥ 48, allowing a small number of long fragments whose length does not exceed 50 mm.
Broken without injury, this is another advantage of qualified tempered glass!
Summary
The above is the "two tortures in the window and door laboratory", for sure, in Sayyas window and door laboratory, there are many strict experiments are carried out every day.
This is the road that every successful aluminum clad wood window must go through before it is born. We firmly believe in the truth that "the more you suffer, the better you will be", which also applies to windows, the stricter the quality, we are serious about making windows!
