Hight Strength Plastic Bar Chair (SP0303B)

Plastic space block for protective layer of reinforcing steel bar is designed according to the requirement of national steel concrete construal design norm. It is widely applied in the civil and industrial construction of buildings, roads, bridges, tunnels, airports, subway and so on. And the clip style spacer usually used in the bevel of the construction. Clip plastic special use at the inclined plane.

Product Character: Having the advantages of high bearing capacity, self locking, crash-proof, good coherence, and easy operation. It is free from the potential quality problems of instable thickness of the protective layer resulting form the use of traditional materials of coprolites and sands.

Code: SP0151B-SP01801B, protection layer: 15mm-80mm
Executive Standards: GBT10-89 Q/SJLX01-2000
Compression Strength: ≥ 4.2Mpa
Tensile Strength: ≥ 4 Mpa

Zinc Sulfide Lens

Multi-spectral grade of zinc sulfide has low absorption and scatter properties over its broad transmission range of 0.4 - 12μm. Zinc Sulfide Multispectral is a chemically vapor deposited material which is commonly used in thermal imaging. With its excellent transmission properties in the visible and infrared, Zinc Sulfide Multispectral is the material of choice for systems that have both visible and mid-wave or long-wave infrared sensors. It is slightly harder and more chemically resistant than zinc selenide.

We consistently offer various high quality optical components according to the customer's requirements use other infrared materials. Such as prisms,Spherical Lens, aspherial lens,Ball lens,Optical Windows,Achromatic Lens,cylinder lens etc.
