Knife-type gate valve for mining coal-fired power plant, slagging, urban sewage treatment, food, paper, medicine, petroleum, chemical and other oil, water, steam pipeline, connect or cut off the pipeline slurry, gold Powder, Ores, Slag, Slime, Pulp, Wood Pulp, Tailings, Fibers, Dust, Chemical Wastewater, Sedimentation Tanks, Bitumen, Silo Exports, Fruits, Cereal, Slaughterhouse Wastewater and other media. 1. Can improve the sealing surface of the shutter, can scrape the sealing surface of the adhesive, automatically remove debris. 2. Stainless steel gate to prevent corrosion caused by leakage seal, grinding and polishing can get better sealing effect. The bottom end of the blade is processed into a knife-edge shape, which has the function of cutting off the soft materials such as fiber, pulp and wood pulp and has a good function of opening and closing. In the upper edge of the blade is installed a hard Teflon scraper to prevent dust, gravel and other abrasives into the stuffing box, can significantly increase the life of the knife. 3. Stainless steel body durable, body rib design to improve the body strength, double-headed screw opening and closing more quickly. 4. The overall stainless steel, to prevent corrosion damage. The valve body and packing culvert are all precision castings, of which the valve body is flanged and integrally cast, the material can be selected according to user needs 304,316,316L, WCB, 2Crl3, PTFE reinforced PTFE ring PTFE material, corrosion resistance, Wear-resistant, non-stick residue. 5. Full circular DC channel design does not slag, no jamming. 6.Scientific seal packing design, so that the seal is safe and effective, durable. 7. Short structural length, can save raw materials, installation space, but also effectively support the pipe strength. Triangular bracket to save raw materials, to ensure the mechanical properties needed. 9. Knife gate valve body guide block to make the correct movement gate. Squeeze block to ensure effective sealing of the gate. 10. Knife gate valve can also choose any drive mechanism. 11. V-type gate can be used as a control valve. 12. Compact design, small footprint, light weight, low price, easy to install, wear-resistant anti-blocking measures to improve, easy maintenance, easy to use and long life, and optional drive. 13. Valve plate has 5 support points, so that the valve plate has a good self-aligning. When the valve is closed, and withstand back pressure, the valve plate does not shift.

Pigment&Dye
Pigment must have a high tinting strength relative to the materials it colors. It must be stable in solid form at ambient temperatures.
Pigments are used for coloring paint, ink, plastic, construction, fabric, cosmetics, food, and other materials. Most pigments used in manufacturing are dry colorants, usually ground into a fine powder. For use in paint, this powder is added to a binder (or vehicle), a relatively neutral or colorless material that suspends the pigment and gives the paint its adhesion. A colorant can act as either a pigment or a dye depending on the vehicle involved. In some cases, a pigment can be manufactured from a dye by precipitating a soluble dye with a metallic salt.
