PVC plasticizers is committed to environmental protection PVC plasticizers transition

Although widely used plasticizer for PVC plastic materials is essential, but it is  zinc stearate extremely regrettable that, as has been pointed out phthalate plasticizers potentially carcinogenic, so, for its application, we will have a different sound. If it’s been proven carcinogenic, so a lot of use of plasticizers to PVC production industry will freeze weak, like food packaging materials, medical devices and children’s toys. More importantly, people in contact with these products frequently more important to human health has a great impact. So if their material is so people “talk about their mere mention.” Well, how else would damage their health products to pay for it? And, as people’s awareness of environmental protection, they are increasingly focusing on the green with harmless products. So, if vendors just to reap tangible benefits and profits at the expense of the health of consumers to produce products. So, destined to  Plastic impact modifier be eliminated by the competitive market. Nowadays, conventional PVC plasticizers application has gradually been limited, but insects hundred die hard to be pulled out of it quickly is not possible in conventional PVC plasticizers still exist in some areas of production, and The most important point is that the new type of green PVC plasticizers common characteristics of high cost, which gives the opportunity to drill a conventional plasticizer free. But we all know that new things are bound to overcome the old things, the good news is, now at home and  Metallic stearate abroad has begun production or development of new environmentally friendly pvc plasticizer catalyst; such as sodium bisulfite class, solid super acid, p-toluenesulfonic , inorganic salts, amino acids and heteropoly acids and the like.

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 .

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.

The new varieties developed chemical structure of the pigment

Only in the case of heating to be dissolved in concentrated acids , organic solvents and insoluble in an organic binder , a high heat resistance , α-Fe2O3 generally heat resistance up to 1200 ℃. Iron oxide red pigment is inert , iron oxide pigments are the most stable one , with good weather resistance, light, water and atmospheric effects is very stable and  Calcium stearate can strongly absorb ultraviolet light , leaving the red iron to protect the items from UV damage . For rust , and is based on its dense coating obtained on the items covered by the shield from the physical effects [ 13,14 ] , while iron red rust on the base have the ability , the ability of dirty gas , alkali , coloring force , hiding power . Due to the low prices, wide range of applications in rust , but rust resistance 1.2 micaceous iron oxide

the difference between organic pigments and dyes where

So that the water can not be distinguished as a standard color dyes PVC flame retardant  and pigments, which difference is the way the object of coloring dye can penetrate into the interior of the object is colored, such as the internal fiber; only act on the pigment surface, such as the surface of the cloth.
Follows:
Fine powder pigment is a colored material, generally insoluble in water, oils and solvents, but can be uniformly dispersed therein. Paint pigments are secondary film-forming substances, and modulation primer, putty and  PVC lubricants colored wood was decorated in wood process, often using pigments. Because of the opaque paint pigments into their film has some color and opacity. Coating the pigment while also enhancing the durability, weather resistance, abrasion resistance.
Dyes and Pigments different, it is soluble in the liquid colored material in water, alcohol, oil, or other Aluminum hydroxide  solvents. Dye solution can penetrate the wood, and the composition of the material of wood (cellulose, lignin and hemicellulose) complex physical and chemical reactions occur, but will not make vague colored wood grain of the wood, the wood can be dyed bright and fastness color.

What is the pigment tinting strength and hiding power

As production Paintbox dye industry, we have to understand very thorough knowledge of the industry. So as to produce more excellent products, quality is more reliable products. So, what is the pigment tinting strength? Today we introduce to you simply. Pointing color tinting strength pigment effect level (also refers to the color intensity)
Tinting strength and dispersion of related, but it is important decisions on their own crystal structure and optical properties. Coloring power can be used to dilute the test pigment with a white pigment used to dilute Metallic stearate  the standards to a certain extent to a certain extent the pigment ratio of the amount of the white pigment used in percentage. Cover means hiding pigment coloring pigment, so that it no longer significant penetration ability, which is the opposite of transparency expressed. The refractive index of the pigment / binder is a transparent refractive index of a pigment> an opaque pigment, the hiding power, the hiding power is also displayed depending on the extent of absorption and dispersion of light.
Technological innovation, simple and strict, standardized management. The  PVC lubricants main business of organic pigments, phthalocyanine blue, phthalocyanine green, acid dyes, various phthalocyanine dyes, azo dyes, vat dyes, reactive dyes, food grade dyes, welcomes you.
In the application of the organic pigment fine particles are uniformly dispersed in the application media, although the application of the molecular structure on the properties of organic pigments play an important role, but the organic pigment particles are applied to its performance has a great influence. After the determination of the chemical structure of the pigment, with almost all of the difference in the physical properties of the solid particles but their application is very chromium oxide  different properties of the pigment of the pigment producers “pigment of processing” This term is not strange, but the vast majority of Pigment production engineers know that “pigmentation process,” what are methods. Indeed, the current method of processing the pigment in the pigment industry is nothing more than these types used: acid soluble, soreness, milling, kneading, solvents and surface active agent.

What flame retardant treated wood impregnation method

Liquid fire retardant impregnated wood, pine and ash timber specimen, select PVC lubricants  pressure impregnation, pressure impregnation, pressure impregnation after microwave treatment, ultrasonic and microwave processing ultrasonic pressure impregnation pressure impregnation of five retardant wood treatment, after testing, exploring the feasibility of introducing microwave and ultrasound technology in the production of fire-retardant wood impregnation method, find the effect of a good wood fire-retardant treatment. The innovation of this study is to microwave treatment with ultrasonic radiation technology applied to the wood fire-retardant treatment, the use of microwave heat treatment to improve the permeability of the wood structure, the PVC plasticizer  use of ultrasonic cavitation enhanced flame immersed in performance and proposed a new technology roadmap. Wood is one of the most widely used building material uses, but the flammability of wood in certain occasions to mankind tremendous disaster. To reduce the threat of fire wood, to be its fire-retardant treatment. Current research focus on wood flame retardants and flame retardant mostly focused on the mechanism, the cutting-edge topics in basic research is to permeable timber of fluid permeability of wood as an important matter.
