  What is meant by space truss? Space trusses are three-dimensional structures with longitudinal members connected at their ends by hinges assumed to be frictionless. The loads on space trusses are applied only at the nodes or joints, thus the self-weight is allocated for each element at its two ends joining other elements of the truss. What is the difference between plane truss and space truss? A planar truss is one where all members and nodes lie within a two-dimensional plane, while a space truss has members and nodes that extend into three dimensions. The top beams in a truss are called top chords and are typically in compression, the bottom beams are called bottom chords, and are typically in tension. What are space trusses used for? Space truss is commonly used in three-dimensional structural element. The forces are subjected axially in space truss elements, which are assumed pin connected where all the loads act only at joints . What is space truss structure system? Abstract...

  There are many kinds of furniture panels, and people who look at it are dazzled. So, which of the common panels is MDF or solid wood particle board? Let's get to know it now. 1. The advantages and disadvantages of medium density fiberboard Medium-density fiberboard   is commonly known as density board. It is a man-made board made of wood fiber or other plant fibers and applied with adhesive. According to its density, it can be divided into high-density fiberboard, medium-density fiberboard and low-density fiberboard. Among them, the nominal density of medium-density fiberboard is in the range of 650KG/square meter-800KG/square meter, and the environmental protection level can reach E1. advantage: 1. The internal organizational structure is uniform, the performance is stable, and the physical index does not change much under different environments, so it is not easy to deform. 2. The surface is smooth and delicate, which is convenient for finishing and saving paint, and the b...

   The effective solution to the yellowing of elastomers is to add  antioxidants   and ultraviolet absorbers, which can effectively prevent and delay the yellowing. However, there are many kinds of antioxidants, and the selection of suitable products requires certain technical support and experience accumulation. The main culprit of oxidative yellowing of elastomers is ultraviolet rays, which are mainly from sunlight. Therefore, especially in the face of customers whose products need to be used outdoors, we will recommend adding a certain amount of ultraviolet absorbers to the products. , Can effectively absorb ultraviolet rays and delay yellowing. Moreover, the use of ultraviolet rays and antioxidants together can play a synergistic effect, and the effect of 1 plus 1 is greater than 2. 2. What are the different classifications and mechanisms of antioxidants? The classification of antioxidants, one is the main antioxidant: capture peroxidative free radicals, mainly h...
