In the past, people used to use side cutting to intercept wood. The cut is tangent to the annual ring of the wood. There are different annual rings of wood on the opposite sides of the same piece of wood. Therefore, it is easy to be warped or twisted due to different water shrinkage rates, resulting in waste of wood. Because of the influence of climate, nutrition, etc., the quality of wood grown in different years is different, reflected in the annual rings, wide and narrow, loose and dense. In order to overcome the drawbacks caused by this, scientists have invented a new method of cutting wood in the direction of radiation, that is, cutting from the center of the wood, so that the cutting line is perpendicular to the annual ring. The wood board thus cut does not have the corresponding point material difference on the two faces, and the only material difference is in the width. Therefore, after the water shrinks and shrinks, the width of the board changes slightly, but the deformation is never twisted, thereby greatly improving the utilization rate of the wood. A BBQ grill mat is a non-stick mat that can be placed on top of a grill to prevent food from sticking and falling through the grates. It is typically made of heat-resistant materials such as PTFE (polytetrafluoroethylene) or silicone. The mat creates a barrier between the food and the grill, allowing for easy flipping and preventing flare-ups. It also helps to distribute heat evenly and can be used for cooking a variety of foods, including vegetables, fish, and delicate items like eggs or pancakes. The BBQ grill mat is reusable, easy to clean, and can be used on gas, charcoal, or electric grills.
