How to use flame retardant to cover a Lamp Shade?--Novista Chemicals
2015 / 10 / 19
According the the National Fire Protection Association, 84 percent of all civilian fire deaths result from home structure fires. To protect yourself, you need to protect your home. Many lamp shades are made out of cloth, and that cloth will spread fire quickly if the bulb it's shading catches fire. One preventative step you can take is to cover the lamp shade in your home with fire retardant. It's a quick and easy step to making your home safe. 1.Purchase indoor fire retardant from a home supply store. 2.Pour the fire retardant into a spray bottle if it was not purchased in one. 3.Keep children and pets out of the room where the lamp shade you are spraying is located. 4.Remove the shade from the lamp fixture. Set the lamp down on a carpeted surface. 5.Spray a mist of fire retardant on both sides of the lamp shade. Make sure the entire shade is covered, but do not soak the shade. 6.Wait for the lamp shade to dry. This should take only a matter of minutes if sprayed properly. 7.Return the shade to the lamp fixture. Children and pets may re-enter the room.
How to use polyethylene flame retardant?--Novista Chemicals
2015 / 10 / 19
1.Add a halogen-containing flame retardant to polyethylene during processing. Bromine and chlorine are halogens used in fire-retardant compounds. Polyethylene is usually produced with fillers, unreactive compounds added to the polymer. Brominated compounds are the most widely used fire-retardant compounds. Add them instead of filler. Brominated compounds prevent fires, because they break down at high temperatures, such as those produced by a fire, and form water and bromide radicals which quench the fire. 2.Add antimony trioxide together with a brominated compound to polyethylene during processing. Antimony trioxide acts synergistically with brominated compounds to enhance fire-retardant properties by slowing down the combustion process. 3.Add a phosphorus-containing compound together with a brominated compound to make polyethylene fire retardant. Phosphorus flame retardants prevent fire by promoting charring. In case of fire, a phosphorus compound will release phosphoric acid, which produces a thick layer of carbon and will cut off the fuel for the flame. 4.Add hydrated aluminum oxide or magnesium oxide alone or together with bromine or phosphorus compounds to low density polyethylene. During a fire, these compounds decompose and absorb energy. They reduce the fire by releasing water and form a fire barrier by charring. Alum oxide and magnesium oxide are non-toxic, non-volatile and environmentally friendly.
What is flame retardant?--Novista Chemicals
2015 / 10 / 19
Flame retardants are compounds added to manufactured materials, such as plastics and textiles, and surface finishes and coatings that inhibit, suppress, or delay the production of flames to prevent the spread of fire. They may be mixed with the base material (additive flame retardants) or chemically bonded to it (reactive flame retardants).Mineral flame retardants are typically additive while organohalogen and organophosphorus compounds can be either reactive or additive. Effectiveness The effectiveness of flame retardant chemicals at reducing the flammability of consumer products in house fires is disputed. Advocates for the flame retardant industry, such as the American Chemistry Council`s North American Flame Retardant Alliance, cite a study from the National Bureau of Standards indicating that a room filled with flame-retarded products (a polyurethane foam-padded chair and several other objects, including cabinetry and electronics) offered a 15-fold greater time window for occupants to escape the room than a similar room free of flame retardants.However, critics of this position, including the lead study author, argue that the levels of flame retardant used in the 1988 study, while found commercially, are much higher than the levels required by TB 117 and used broadly in the United States in upholstered furniture. Another study concluded flame retardants are an effective tool to reduce fire risks without creating toxic emissions. Several studies in the 1980s tested ignition in whole pieces of furniture with different upholstery and filling types, including different flame retardant formulations. In particular, they looked at maximum heat release and time to maximum heat release, two key indicators of fire danger. These studies found that the type of fabric covering had a large influence on ease of ignition, that cotton fillings were much less flammable than polyurethane foam fillings, and that an

CPVC Hot & Cold Water Piping introduction
2016 / 08 / 05
Chlorinated polyvinyl chloride (CPVC) pipe, tube, and fittings have been successfully used in hot- and cold-water distribution systems since 1960. From 1960 to 2000, enough CPVC tubing was sold to plumb millions of typical single-family dwelling units and usage increases each year. The products consist of ASTM D2846 SDR 11 CPVC tubing manufactured to Copper Tube Size (CTS) ODs (outside diameters) and CPVC sockettype fittings. The ASTM D2846 standard cover sizes ½-inch through 2-inch and both the tubing and fittings are tan in color. As hot and cold water piping, the system carries a continuous use rating of 100 psi at 180° F and 400 psi at 73° F. When sizes larger than 2-inch are needed, ASTM F441 Schedule 80 CPVC pipe made to iron pipe size (IPS) ODs and ASTM F437 and F439 Schedule 80 CPVC fittings are used. Plumbing codes may require proof testing of assemblies for 48 hours at 150 psi and 210° F. Most producers have had these tests performed to qualify their products for use under such codes. CPVC CTS tube and CPVC IPS Schedule 80 pipe is sold in straight lengths. Smaller diameter CTS tube is also sold in coils. 8. Cooling and Solidification Stage Working component: water bath, cooling fan The extruded product is quickly cooled and solidified by the cooling system to maintain its shape and dimensional stability. Cooling methods include water bath cooling, air cooling, etc. 9. Cutting and Post-processing Stage After the cooling stage, the solidified plastic can be further processed, especially in plastic modification applications. At this stage, precision becomes critical. The solidifi
