Since the external object (by force, humidity, etc.) and is deformed in the body to produce the internal forces of interaction between the various parts to withstand the effect of such external factors, Weinan warm wall carbon crystal, and try to make the object from the deformation position back to the position before the deformation. In a cross-sectional study on the basis of the internal forces at a point called stress. With a vertical cross-section is called normal stress or normal stress, the same cross-section tangency is called shear stress or shear stress. Stress will increase and thickening of the external force, for a certain kind of board quality, warm wall carbon crystal which brand is good, stress thickening is limited, beyond this limit, Which is a warm wall carbon crystal warm and good, board would damage the quality. [Crown] you know a new energy heating good road system board should have what requirements? There are two core requirements, first to secure anti-available, how about a warm wall carbon crystal, the other one is the effect to be good. And some users will ask, warm wall carbon crystal set, the disc plate under the wall through the wall for a long time will not it? Our DG - 002 standard HVAC heating plate board is not allowed to have the joint, a circuit board is a whole, all the joints are in a diversity wall is inside, warm wall carbon crystal wall after laying required pressure test excluding possible through the wall. Set warm wall carbon crystal, crystal wall of warm carbon choices attention a lot. Quality heating plate (DG - 007X-A material) performance is warm wall carbon crystal thick, curved plate only when turning sleeve, can do the entire board without connector, can effectively prevent the penetration. Our environmental policy is: caring nature, pollution control, energy conservation and sustainable development. Welcome to inquire! Which is good, warm wall carbon crystal crown _ Energy (online consultation) _ warm wall carbon crystal Hebi in Henan crown by New Energy Technology Co., Ltd.
