Telescopic door manufacturers explain the quality problems of electric doors, the deion and cracking of electric doors, the industry is attributed to rare results, "do not crack, do not call the plain wood"? Is that true? What methods can be dealt with?
1. Electric door cracking, quality is fruitful?
Many enemies assume that if the electric door is cracked, the electric door must be false. In fact, it is unavoidable that even the real electric door will crack.
Even the valuable red sandalwood furniture will crack when it is displayed in the Forbidden City. On the contrary, it needs to be revised.
Almost all famous brands in the past have such rules in their after-sales service: electric door cracking is a natural feature, assuming the responsibility of amending as far as possible and not assuming the responsibility of communication.
If the moisture content of the electric door is not well controlled, the quality results such as cracking and deion will appear. After the door is finished, the moisture content and monotonic stress of the wood choose the appearance of the door and whether the material will change again.
Therefore, it is important to control the moisture content of the electric door properly. The moisture content after balance will not crack and deform due to the environmental factors such as sunshine, supercooling and superheating.
The natural characteristics of the talus choose its variability. After making products, the affirmative extension is unavoidable. Electric door enterprises can not stop dealing with this phenomenon, but can stop reasonable control from some aspects, so cracking can be avoided.
The water content requirement of the electric door is one to two percentage points lower than the theoretical air uniform water content. Because of the difference of astronomical position, the climate of our country is not the same, so the requirement of water content of electric door is different.
For example, the average annual water content in Beijing is 11.4%, so the water content of electric door should be controlled at 10.4% or 9.4%. In the south, the average water content of air is 14%, while in the south, 12% to 13% is requested.
Therefore, some electric doors manufactured in the South will crack when they are transported to the south, while the electric doors manufactured in the South will shrink and cannot close when they are transported to the south.
Electric doors will inevitably bump and bump in the course of transportation, so we should pay attention to the wings during transportation. Although electric doors are more "stable" than other materials, they are difficult to escape if they are not well taken care of.
