Extensive use of pigments

Pigment ink is a pigment ink aggregates consisting of molecules, the molecular diameter of which is much greater than the smallest unit of the dye ink, ranging from 50 to 200 nanometers, usually in the form of the  Plastic impact modifier presence of an opaque liquid. Pigment ink right image point is powdered ink, of course, this is just kind of image of the argument, and not accurate enough. Accurate to say that it is the solid pigment ground into very small particles, dissolved in a special water solvent, is called a semi-solution solution or suspension, with the nature of our pigment dyeing clothes also. Penetrate into the media with dye ink color and then formed exactly the opposite principle, it is through color material attached to the medium (such as copy paper or printing paper) to the surface of the hair color. Therefore, under the influence of external corrosion damage first only the outermost molecular structure inside the  one pack stabilizer structure is not easily damaged, destroyed after the outer layer of molecules, such phenomena appear faded. For color printing, the ink because the pigment of the outer layer of the polymer, it will not exhibit good color and vividness of color, even in the light printing paper sheet having a flat surface can not print glossy images, which is why general use pigment inks to print out the reason things are not shiny. Advantages: waterproof light. Disadvantages: large particles, it is likely to cause the plug, the color of the printed image is not good, not bright. 2 Dye ink Dye ink is totally dissolved at the molecular level of the ink is generally from 1 to 2 nm in diameter, Dan Jun supplies INKOOL brand ink technology more carbon collar diameter approaches zero; compound The ink solution is complete, the Azodicarbonamide  ink blocking Probability head is small, easy to be absorbed by the material after printing and printing on smooth paper, light radiation performance is very good, so the ability of strong color reproduction, print out the picture colorful, low-cost and cost ; but because unlike the dye ink Pigment ink as a protective surface layer of polymer, and therefore under harsh conditions, molecules are readily decomposed, resulting in discoloration.

Plastic heat stabilizer is recommended usage and molding temperature

1, in the PVC pipe, fittings , profiles generally recommended dosage is about 2 parts . Because of the  Titanium dioxide rutile lubrication -free thermal stabilizers , and the composite powder of lead calcium / zinc, adding more lubricant itself stabilizer compared to the poor slipperiness , and therefore required in the formulation according to the temperature change during processing and molding products such as surface smoothness of a case appropriate increase in the lubricant , especially the amount of external lubricant melting point ;
2, the organic calcium having good thermal stabilizer pre- plasticization process can reduce the current host , to reduce energy consumption ;
3 , depending on the original formula processing temperature systems and equipment , lower than the original 5-10 ℃, without affecting the processing flow and product performance ;
4 , with the company developed QS Series Composite lubricant use, better performance and Aluminum hydroxide  long-term initial color thermal stability . Recommend adding 1 part component composite lubricant around .

Some of the major pigment brief introduction

Now paint on the market can be said to be varied, to judge whether it is truly  Titanium dioxide rutile green paint coatings, we need to pay attention to the following aspects.
1 , red iron oxide pigments in various types of precast concrete products and construction data as a pigment or coloring agents, directly transferred to the cement used. Various colorful concrete exterior room table , a variety of construction ceramics and glass ceramics.
2 , red iron oxide color pigments for a variety of coatings and maintenance materials , also  PVC plasticizer apply to oily Lo epoxy enamel , alkyd , amino and other primers and topcoats ;
3 , iron Pink paint color for plastic products , such as thermosets and thermoplastics , and colored rubber products such as automobile tire, aircraft tube , bicycle inner tubes and so on.
4 , popular and used in the construction of iron , rubber, plastics , paint and other industries, especially iron red with rust primer function, can replace expensive red lead paint , saving non-ferrous metals . Grinding and high-grade materials, equipment used for fine metal , optical glass polishing . High purity is the primary base powder metallurgy used to exercise various Aluminum hydroxide  magnetic alloys and other high-grade alloy steel .
5 , used in paints , rubber, plastics , paint and other construction , in addition to iron oxide pigments can also be used for all kinds of cosmetics , paper, leather color .

Efficiency of halogen-free flame retardants

Halogen-free flame retardant is an efficient system of phosphorus and nitrogen , and Plastic impact modifier  made ​​a small amount of smoke halogen-free flame retardant , does not produce toxic, corrosive gases. Halogen-free flame retardant additives mainly phosphorus compounds and metal hydroxides as. These two compounds , combustion is not volatile, does not produce corrosive gases , pollution-free flame retardants are called , is an ideal environmentally friendly products :
Halogen-free flame retardant is a phosphorus-nitrogen based organic flame retardant high performance , a triazine compound and a triazine trione compound triamines , after a special surface treatment, it is easily dispersed in  aluminium stearate the plastic material , no precipitated with good flame-retardant effect . W666 decomposition temperature of about 450 ℃, the maximum particle size (D50%) of 20/um, the appearance of white powder , a high temperature does not affect the color of the product recommended for high-performance halogen flame retardant polyamide ( nylon ) is widely used in epoxy resins , polyurethane , polystyrene, polyester (PET, PBT), and halogen-free polyolefin wire and cable is recommended to add 15% -30% of the Azodicarbonamide  halogen-free flame retardants W666, you can reach V0 94UL -V2 standard .

The main introduction of polyurethane flame retardants

The polyurethane material is a polyol isocyanate reaction and synthesis of a  aluminium stearate polymer containing urethane materials , polymer materials are widely used in such adhesives, coatings, low tire , washers, car mats and other industrial fields. In the areas of daily life are used to manufacture a variety of polyurethane foam and insulation materials. However, because the host material is a polyether polyurethane polyol and a polyisocyanate reactive synthetic polymers , mostly consisting of carbon , hydrogen, oxygen and other elements , which has flammability, environmental and human safety of the potential threat. Therefore, improving the flame retardant polyurethane material has become an urgent problem to be solved . So adding a flame retardant in polyurethane materials is imperative .The flame retardant effect is to delay or prevent combustion of the combustion speed . When adding a flame retardant polyurethane  Chlorinated paraffin contact with fire , burning speed can slow down ; When leaving the ignition source , could soon be self-extinguishing . Flame retardant mechanism is very complex, in short, is in some way to achieve the purpose of cutting off or blocking the combustion cycle .Here to talk about where the flame retardants used in the polyurethane :First, Brominated : Brominated flame retardants absolute dominance in the organic flame retardant system , although on environmental issues , ” criticism ” multiport it has not been difficult to have replaced other flame retardant systemTwo red phosphorus :In the non-halogen flame retardants , red phosphorus is a better flame retardant, with  Aluminum hydroxide less added flame retardant, high efficiency , low smoke , low toxicity , etc. widely .But ordinary red phosphorus easily oxidized in air, moisture, dust explosion prone , transportation difficulties , and poor compatibility with the polymer material defect , the application has been limited.
