I. Series of ball valve
Ball valve has two types of structure, which of split body and three-piece body. Besides small fluid resistance, fast opening and closing, simple structure, has the following features:
  1. Ball valve with FEP lining has high chemical stability, can be applicable far any strong corrosive medium except molten alkali metal and fluorene.
  2. The structure of full bore, floating ball can class under full pressure without leakage- is also convenient for pipeline pigging and pipeline maintenance
  3. Compact structure and smallest space of valve cavity reduced medium retention. In addition, special molding process make the sealing face has good sealing, plus the PTFE packing, the valve can realize no leakage.
  4. Structure of split body and three-piece body could be applicable for pipeline system of any requirements and services, in which valve of three-piece body allows main valve body to separate from valve body of two sides: can realize quick replacement and maintenance on site.

The main function of the edge banding is to seal the cross-section of the board, so as to avoid the damage of the board and the adverse factors (mainly moisture) in the process of use and prevent the formaldehyde inside the board from volatilizing, and at the same time achieve the effect of beautiful decoration.
The product has the following main features: smooth surface, no blistering, no ribbing, moderate gloss, smooth surface and back surface, uniform thickness, uniform width, reasonable hardness, high elasticity, good quality, strong wear resistance, trimmed and sealed The color of the side and the side is close to the surface color, not whitish, good gloss, and the overall color of the finished furniture is coordinated.
PVC furniture edge banding is relatively light, which is relative to metal and plexiglass. The reason for the lightness is not because it is a polymer compound, but because they are organic compounds, which are composed of carbon, hydrogen, oxygen, and chlorine. And other lighter elements.
The material of pvc furniture edge banding is plastic, which is easy to process. Plastic has plasticity, that is, it deforms after heating or pressurizing, and maintains its original shape after the temperature drops or the pressure disappears. It can be processed into edge bands of their respective shapes by extrusion and other methods, such as T-shaped edge bands, H-shaped edge bands, D-shaped edge bands, V-shaped edge bands, I-shapes, and so on.
pvc furniture edge banding is of high quality and low price, and the price of plastic is far less than that of metal.
