SPRING SELECTION GUIDE 
-Standard Spring Suitable for the line pressure of 0.298MPa through 0.89MPa without any pressure loss and the upward flow direction of vertical installation.
-Low Coil Spring Ideal for gas with the line pressure of 0.1MPa and under.
-High Coil Spring Suitable for the line pressure of 0.88MPa.

THE SEAT DESIGN OF DUAL PLATE CHECK VALVE
-No leak, no distortion seals Seat design can be furnished with the resilient seal materials that provide tight seals without leakage and metal seals with minimum leakage.

ADVANTAGE
-Face-to-face dimensions for Dual Plate Wafer Check Valves are about one fourth of a Swing Check Valve.
-Weight is as little as about 20% of the corresponding Swing Check Valve due to the compact design.
-Dual Plate Wafer Check Valves have a spring design to close valves more efficiently when the back flow occurs to reduce the water hammer.
-These valves have the lower pressure drop than Swing Check Valves because of little friction resistance.
-Dual Plate Wafer Check Valves are less expensive than Swing Check Valves because of the lightness and compact design. These valves are also easier and less expensive to install and maintain because of fewer piping supports and easy handling for installation.
-Because Dual Plate Wafer Check Valves are flangeless, they are installed between flanges.
-Normal installation method for horizontal flow is with the hinge pin in vertical position.
-Installation is available for both horizontal and vertical piping.

Hot Melt Adhesive For Wet Tissue Cover

Hot melt adhesive is a solvent-free new environmentally friendly material, the formula is based on polyurethane for various characteristics design, at room temperature is a solid, heating more than the melting point will melt into a viscous liquid, for bonding processing, cooling to room temperature and then back to solid, belongs to reversible thermal plasticity material, with good elasticity, flexibility and low and high temperature resistance and other characteristics. It has strong bonding effect on a variety of different materials.

Hot melt adhesive mainly consists of hot melt adhesive block and hot melt adhesive pellet. Because it is solvent-free and 100% solid, there is no danger of flammability or explosion during processing and transportation. In addition, there are the following advantages:

(1) Fast curing speed, cooling is curing, high production speed, saving Equipment space.
(2) The bonding process is simple, less waste, and there is no mixing problem.
(3) 100% solidified components, can be fully utilized, less waste, can reduce transportation and storage costs.
(4) can be followed by a wide range of substrates, can be automated processing.
(5) excellent chemical and physical properties, with high bonding strength and flexibility.
(6) Do not use organic solvents, no VOC pollution problems.
(7) Environmentally friendly materials, waste can be naturally degraded.
(8) moderate fluidity, strong adhesion, less bubbles, good temperature resistance and other advantages.

More and more varieties of hot melt adhesive, more and more widely used, can be bonded leather, books, pearl cotton, hand bags, plastic bags, clothing, cartons, etc., can be used in packaging (corrugated paper and thick cartons), wireless binding of books, etc.

In general, hot melt adhesive has different applications in all walks of life, the specific parameters and usage are not the same, we need to choose different corresponding hot melt adhesive according to different industries, so as to ensure the quality of work more accurately and efficiently. In the future, the application range of hot melt adhesives will be more extensive, because they are healthy and environmentally friendly, high viscosity and non-stimulating, greatly shortening the working time, improving the work efficiency, and reducing the production of human and material resources.
