Wood-plastic composites (Wood-Plastic Composites, WPC) is a new type of composite material that has been booming at home and abroad in recent years. It refers to the use of polyethylene, polypropylene, polyvinyl chloride, etc. instead of the usual resin adhesives. More than 35%-70% of wood fiber, rice husk, straw and other waste plant fibers are mixed into new wood materials, and then the plastics processing technology such as extrusion, molding, injection molding, etc., produces sheets or profiles. Mainly used in building materials, furniture, logistics and packaging industries. The plastic and wood flour mixed in a certain proportion after the hot extrusion of the sheet, called extrusion wood-plastic composite sheet. (1) waterproof, moisture-proof. It fundamentally solves the problem that wood products are easily rotted and distort after moisture absorption in wet and multi-water environments, and can be used in environments where traditional wood products cannot be applied.
(2) Prevent insects and termites, effectively eliminate pest harassment and prolong lifespan.
(3) Colorful, many colors to choose from. Both natural wood texture and wood texture, but also can customize the desired color according to their own personality [3]
(4) It has strong plasticity and can be very simple to achieve personalized modeling, fully reflecting the personality style.
(5) High environmental protection, no pollution, no pollution, and can be recycled. The product does not contain benzene substances, and the formaldehyde content is 0.2, which is lower than the EO level standard. It is a European-level environmental protection standard. Recyclable use greatly saves the amount of wood used, is suitable for the sustainable development of the national policy, and benefits the society.
(6) High fire resistance. Can effectively flame-retardant, fire rating to B1 level, self-extinguishment in the event of fire, does not produce any toxic gases.
(7) Good machinability, can be customized, planed, sawable, drillable, paintable on the surface.
(8) Simple installation, convenient construction, no complicated construction process, saving installation time and costs.
(9) No cracking, no expansion, no deformation, no maintenance and maintenance, easy to clean, and save the cost of later maintenance and repair.
(10) Sound absorption effect is good, energy saving is good, so that the indoor energy-saving up to 30%.
HHCMS-200 carbon molecular sieves
CMS-200 is a new kind of non-polar adsorbent specially designed for extracting nitrogen-rich gas from air. It is suitable for separating nitrogen from air. It has a high adsorption capacity for oxygen and can separate nitrogen from air.
The most notable feature of the Carbon Molecular Sieve is its high gas-producing efficiency, especially the preparation of nitrogen with a purity of less than 99.5%.
It is widely used in large air nitrogen making equipment.

Pay attention to
1. The nitrogen production equipment can reduce the adsorption temperature to better show its excellent nitrogen production performance under conditions;
2. Pay attention to low temperature drying and seal preservation during storage;
