Flame retardants
Most plastics are flammable . With the plastic in the construction, furniture, transportation, aviation , aerospace , electrical and other aspects of the widely used to improve the flame retardancy of plastics has carbon black powder become a very urgent issue. Inhibiting polymer flame retardant is a class of flammability additives, they are mostly of the Periodic Table Ⅴ, Ⅶ Ⅲ elements and compounds ; especially phosphorus , bromine , chlorine , antimony and aluminum compounds. Sub- additive flame retardants and reactive types . Flame retardant halogen-containing primarily phosphate and Acrylic processing aid phosphate, a halogenated hydrocarbon , antimony oxide , and aluminum hydroxide . Advantage is easy to use and adaptable . However, the addition of capacity of 10 % to 30% , often affect the performance of plastics . Reactive flame retardant containing the elements actually monomer, it has little effect on the plastic properties . Common reactive flame retardants , halogenated anhydrides such as for polyesters , for epoxy resins of tetrabromobisphenol A, and phosphorus for polyurethane polyol. Flame , the current amount of second plasticizer. Consuming most varieties of plastic flame retardant polyvinyl chloride, polystyrene, polyurethane foam , unsaturated polyester , ABS resin and polypropylene.
Most plastic is flammable , its titanium dioxide anatase products, which brought a lot of application security risks. Precisely, flame retardants, flame retardants known as more appropriate , because " flame " contains two meanings flame retardant and smoke suppression , compared with the broader concept of flame retardants . However , long time, people have become accustomed to the concept of use of flame retardants

Analysis of the use of natural red iron oxide
Iron oxide red do you know? Professionals may be more familiar with such items. Today we'll learn a wide range of uses of natural iron oxide red! Look at it together!
Red iron oxide has both natural and Metal stearate artificial. West said the natural red. A substantially pure iron oxide. Red powder. As production methods and operating conditions, their crystal structure and physical properties are very different, color changes from orange to blue to violet light between. Hiding power and tinting strength are great. There are excellent light, high temperature performance and resistance to atmospheric effects, resistance to dirty gas, all the alkali resistance. Only in optical brightener concentrated acid under heating was gradually dissolved.
Natural red iron oxide has good coloring power, the production of ultra-fine natural red iron oxide pigments, the main chemical ingredient, fine texture, pure color, particle size distribution science, measured by the Chinese Institute of Chemical Industry Metals data indicate that, in similar products , it is non-toxic, high temperature, not with acid, alkali, salt effect, is replaced Hongdan green pigments. Surface to be easily attached to dust, Every time there was rain Xueshuang, more so the film surface scrub as new, soft lead stearate colors and elegant, do not fade, change color, replace part of red iron oxide. Natural red iron oxide is mainly used for the production of iron red paint industry series primer, paint, mixed paint and high-grade paint colors such species or building components for color, natural red iron oxide can replace the roots of materials and precipitated barium sulfate , talc and other fillers. ...

PVC heat stabilizers and mechanism
PVC is the first ideal structure - tail structure-CH2-CHCl-CH2-CHCl-, is quite stable. But so far the PVC synthesis method can not be like synthetic butadiene rubber, as the role of catalyst in Jigger so there are rules for orientation cis butadiene polymerization is a free radical polymerization of vinyl chloride random polymerization, in addition to its stable First - tail structure, as well as the first - the first structure-CH2
-CHCl-CHCl-CH-, tail - tail structure-CHCl-CH2-CH2-CHCl-; generate a coupling disproportionation vinyl Results CH2 = CH-CHCl
-CH2-structure and allyl chloride-CH2-CH = CH-CHCl-CH2 and so on.
Generated in the PVC synthetic allyl chloride, chlorine and tertiary carbon double bond in its molecular chain structure instability, unstable cis
Sequence is: PVC within the molecular chain allyl chloride> tertiary carbon Chlorine> terminal allyl chloride> sec chlorine. PVC processing is easily degraded but because
The PVC molecular chain structure, there vegetable stearic acid is instability factors, such modification not be stabilized, and its decomposition temperature is about 130 ℃, but
PVC resin to be processed into useful articles, molding temperature to above 190 ℃. Therefore, you must add to its junction heat stabilizer
Improved structure for stabilization. Four types of heat stabilizers heat discoloration Comment
Ideal thermal stabilizer should also absorb HCL, remove the active site, the addition of a conjugated polyene chain, from the destruction of carbenium
Sub-salt, to prevent the auto-oxidation and other functions, without generating a catalytic degradation of PVC products. The plastic processing aid actual heat stabilizer due to
Has a different function and behave in a different thermal stability characteristics, can be divided into early-type, long type, intermediate type and versatile
Four categories.
1) cadmium, zinc soap is typical of early-type heat stabilizers, can quickly absorb HCL, and Cd, Zn in the catalyst effectively carboxylic
Replace PVC chain radical unstable chlorine atoms, thereby effectively suppressing the initial degradation and coloring, but because of consumption of fast transformation products CdC12, ZnC12, but also off the HCL PVC efficient catalysts, which will lead to the aluminium distearate degradation of PVC material suddenly becomes a vicious black, so
Long-term thermal stability. 2) barium, calcium soap is a typical long-term thermal stabilizers, absorption HCL function only and therefore can not effectively suppress coloring PVC,
But the transformation products BaC12, CaC12 does not have catalytic activity, does not cause a sudden black PVC, long-term thermal stability. 3) fatty acids, organic tin are intermediate, both absorbs HCL, can effectively replace PVC with chain carboxylate unstable chlorine
Atoms, and conversion products do not have catalytic activity.
