In the process of the flame retardant, most manufacturers use the installation order of addition of the flame retardant wood → → → start retardant adding water. In general, when the wood started to absorb water, Fuzhou fire door prices tend to lead to the wood began to absorb very low concentrations of flame-retardant liquid. Thus, in the process timber retardant, a flame retardant is also required concentration absorbed from the timber to the low concentration of the high concentration of normal procedure, directly affects the dry salt uptake and absorption speed of the timber, thereby affecting the flame retardant effect. Flame retardant sequential addition of water → → → start retardant mounted timber, a timber retardant liquid begins to absorb the standard concentration, avoiding the absorption process retardant liquid timber from a low concentration to the normal concentration is too high, thereby increasing the retardant quality. If the business conditions, flame retardant can first liquid having a predetermined concentration, and then added to the pool flame retardant quality will be better. La EBS manufacturers generally magnesium hydroxide decomposing ability and relatively high thermal capacity. Compared with ordinary inorganic flame retardant magnesium synthetic material can withstand higher temperatures, not only improve the rate of extrusion, but also greatly reduces molding practice. Further, it may also be added to a variety of paints and paints, in order to promote the flame retardant properties of the material. Inorganic flame retardants rich source, low price, but is flame retardant, excessive additives. Flame retardant and a flame retardant into physically mixed flame retardant chemical bonding reaction.Xylenyl Phosphate manufacturer  The basic physical properties required flame retardants are: good compatibility of plastic and synthetic fibers; ② does not change the natural function of the amount of the fine; ③ small amount, a high effect; ④ processing temperature not synthesized; ⑤ small, asexual combustion gases; ⑥ low cost. The main advantage of sealed concrete curing agent is a floor does not require much maintenance, you can reduce maintenance costs. Nitrogen and Phosphorus flame retardant material is still hot art halogen-free flame retardant. Phosphorus-nitrogen flame retardant paper of 40 per cent. Seek efficiency phosphazene flame method is the primary hotspot. Nano, hyperbranched, inorganic composite materials, microcapsules covered phosphaphenanthrene flame synthesized so occupy the mainstream of such paper. Many college teams China University of Technology, Sichuan University, Qingdao University and other papers are concentrated in this area. Phosphorus compound flame retardant can be divided into different phases of the reaction zone and the vapor phase flame retardant mechanism aggregation mechanism, organophosphorus flame retardant in the condensed phase play a role retardant mechanism is as follows: in the combustion process, P decomposition of noncombustible compound film, up to the boiling point ℃ adsorbent product physical and chemical properties of test data Test report - (dry basis) pore volume average particle diameter (laser) (centrifugal sedimentation) (laser) (centrifugal sedimentation) ( laser) (centrifugal sedimentation) (laser) (laser). (3) halogen-free flame retardant in the polymer system material formulation, by weight of a high proportion of halogen-free flame, close to or above the matrix resin material, particle morphology (powder) and the ratio (greater than resin) and the resin matrix difference large, the flame retardant system matrix resin mixed with a dispersion is also very important, which will determine the homogeneity of the material, so that development of processing equipment for processing and halogen free flame retardant system performance characteristics and polymeric materials. The polyolefin compound is gradually substituted compound based on polyvinyl chloride, and are widely used in areas have strict requirements for smoke and toxic gas emission, the field of underground pipes, in public places, insulated wires and cables etc. in particular. Processing these materials at high temperature, the processing temperature reaches 300 ℃. Therefore, many manufacturers polyolefins based on magnesium hydroxide flame retardants produce dense final product. The magnesium hydroxide can improve the processing performance, good mechanical properties, high thermal stability. Formulation used: Silicone flame retardant connecting the reaction as a monomer to the polymer chains, or grafted onto the organosiloxane polymer chain, integration with the base material, a flame retardant, on the one hand prevent the polymer migration of the flame retardant, the flame retardant on the other hand a perfect compatibility with the polymer matrix, which can effectively maintaining or even improving mechanical properties. For example, SFR-100 silicone polymer and polymer binding mechanism and partially crosslinking mechanism similar to an interpenetrating polymer network, can inhibit the flowability of the flame retardant polymer matrix of silicon, to prevent the migration resistance burning the material surface. Because of good compatibility with polypropylene SFR-100, commonly used alone or with other synergist alone (aluminum hydroxide, ammonium polyphosphate, magnesium stearate, etc.). Flame-retardant polypropylene, PP improved flame retardancy and smoke suppression. First, a length of a width of 80 special adhesive applicator 2 in the packaging site, and then pressed into a long mesh 80, the remaining standby throw. 3) a special adhesive applicator configured behind the extruded sheet, the thickness of the adhesive was about 3 compacted.Flame retardant TXP factory  To ensure firm bonding, adhesive bonding method can be employed strip method and article point method. 4) viscosity method: the needle bed gap trowel special adhesive applied in a uniform horizontal extrusion plate, strip width 10, thickness 10, 50 in the distance. One cause of the fire is flame retardant XPS extruded plate lost, leading to the spread of fire. The biggest difference between the ordinary sheet and the board is whether a flame retardant is added, a little lighter weight: 32 kg or more fire-retardant plate on each side, only about 28-31 kg ordinary plate. 'Price is high flame retardant board greatly increased the cost. 'No flame retardant effect is not good common plate, or even that rate is zero flame. In general, the organic flame retardant has a good affinity. In plastic guess, brominated flame retardants has an absolute advantage in the organic flame retardant system. Although criticism multiport on environmental issues, but it is difficult to be replaced Changshu flame retardant system. In the non-halogen flame retardants, red phosphorus is a good flame retardant, has added less, high flame retardant efficiency, low smoke, etc wide use; red phosphorus with aluminum hydroxide, and expanded graphite, inorganic using flame retardant compound, resulting in a phosphorus compound / magnesium; P / Al; P / graphite, other non-halogen flame retardant amount may be greatly reduced, thereby improving the function and the processing functions of mechanical equipment of the finished plastic. However, ordinary red phosphorus is easily oxidized in air, moisture, dust is likely to cause difficulty in transportation, the polymeric material defects and poor compatibility, limited applications.Flame Retardant TXP supplier  Use concrete floor hardener greatly improving the modern building ground mode.
