Magnesium hydroxide and aluminum hydroxide are two different flame retardants. In addition to a fairly influence on the environment, these two flame retardants have obvious contrast in terms of thermal reaction, decomposition temperature, applicable polymer, flame retardant, and the performance of magnesium hydroxide is better than that of aluminum hydroxide resistance.
Cresyl Diphenyl Phosphate supplier Combustion. Today, the seven aspects of magnesium hydroxide and aluminum hydroxide, I hope to help you.
When the flame retardant is heated, the non-combustible gas is decomposed, and the flammable gas concentration decomposed by the combustible material is dilute to the lower limit of combustion. At the same time, the oxygen concentration of the combustion zone is diluted to prevent combustion from continuing to achieve flame retardant effect. Hegang liquid flame retardant sales.
It promotes the cover of the polymer long carbon chain surface active agent on the flame retardant particles, and the mutual winding of the long carbon chain surface active agent and the polymer matrix can improve the interaction force of the powder flame retardant and the matrix resin. Further improve the mechanical properties of the halogen-free flame retardant polymer material.
At present, domestic wood flame retardant treatment is generally in a certain temperature, and the metal storage tank is soaked with aqueous phosphorus, nitrogen, etc., so that the flame retardant penetrates into the wood ≥ 5mm, then dry, then flatly flattened according to the actual size. In the supervision and inspection, we use a lighter to take a small amount of fire door wood, often found that some fire door wood has no flame retardant treatment or wood flame retardant treatment does not reach the corresponding depth, which will seriously affect the fire door of fire door.
In the process of processing, the Hubei flame retardant market has no waste loss. General plastic processing is simple and fast than ordinary woodworking machine tools, which is very important to our production. Do you know the advantages of a five-layer flame retardant? Most of the mid-thick flame retardant plates appear in the form of a plywood, and a flame retardant is added to different layers. However, the thickness of the plywood of different layers is different, and the flame retardant plate is too thick. The flame retardant is not good. The flame retardant effect is good. The five-layer flame retardant plywood can be added multiple times, and the combustion speed of the plate is delayed on the fire resistant effect. High strength, because the flame retardation plate often needs to be fixed with nails, so good grab is determined by the stability of the finished product. The three-layer flame retardant can be used for the backplane, but it cannot be supported as support. The layer of flame retardant plate is high, and the intensity of the layer is high, the pinch is strong, and can be used as a backplane or support.
The halide system, that is, a gas phase flame retardant mechanism. Common halogen flame retardants have tipphenylene ether, hexa bromoate dodecane, octopher ether, tetraromobisphenol A, etc., plus a flame-retardant impetition of trioxide oxide, has less added amount, resistance Good characteristics of fuel effects. However, halogen flame retardants have been restricted by green environmental protection organizations, which are prohibited in some cases.
Compared to the halogen-containing organic flame retardant, in order to achieve a considerable flame retardant effect, usually the amount of filling should reach 50% or more. Since magnesium hydroxide is inorganic, the surface and the polymer substrate are relatively poor. If the surface modification of magnesium hydroxide is not obtained so high fill, the mechanical properties of the composite material after filling into the polymeric material will fall.
News: TYD indoor real news) With people's environmentally friendly, safe, health awareness, countries around the world have begun to use environmentally friendly flame retardants as the focus of R & D and application, and have achieved certain results. The flame retardant is classified according to the effective element, which can be divided into phosphorus, chlorine, bromine, antimony, aluminum, boron flame retardant, and the like. According to the flame retardant effective element, the flame retardant is divided into four flame retardants such as halogen-free flame retardants, bromine flame retardants, halogen-like flame retardants, and several environmentally friendly flame retardants having application prospects are introduced. With the development of my country's material industry, the expansion of the application fields, flame retardants have broad market prospects in chemical building materials, electronic appliances, transportation, aerospace, daily furniture, interior decoration, food, clothing, housing, transportation and other fields.
A textile flame retardant is applied to the computer circuit board, and a textile flame retardant is applied to the plastic housing. Hospital and theater seats and car seats use textile flame retardants. The outer wall insulation material of public buildings is also coated with a textile flame retardant. The environmentally friendly flame retardant is not determined by any tissue and environmental label, but is determined by the structure and performance of the leather flame retardant itself. Environmentally friendly flame retardants must meet the following conditions: First, the flame retardant is environmentally friendly. If you want to consult wood flame retardants and flame retardants, Welcome to the production of flame retardant for more than 10 years of flame retardant.
Diphenyl cresyl phosphate factory 2-Methylphenyl diphenyl phosphate manufacturer
The insulation performance of the extruded plate extruded plate extruded on the XPS polyethylene extruded plate is well known. Extrusion plate manufacturers should pay attention to the following problems in production to increase the quality and performance of the sheet. The project is an extrusion process, which is an incomprehensible link in the production of extruded sheets, and is also one of the important aspects of the quality of extruded board. Reasonable control of the extrusion process is conducive to the quality of the insulation board, and the manufacturer must not be ignored. Adding flame retardants is the second problem that needs attention in extruded board manufacturers. One of the feature of the insulation board is to flame retardant fireproof, so you can't forget to add flame retardants in production. At the same time, pay attention to the amount of flame retardant, can't be too or too little. The specific amount can be determined according to the instructions of the flame retardant and its own experience.
