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.

Iron oxide colors

Iron oxide pigment colors not only about its chemical composition, and its crystal structure type and size of the pigment particles, such as iron oxide red for the α-Fe2O3, iron oxide yellow for the α-Fe2O · H2O, black iron oxide as Fe3O4. In the chemical composition and the same crystal configuration, the small differences in grain size and shape of the pigment has a very important influence on the performance. For wet synthetic red iron oxide, which is nearly spherical particles  Chrolinated polyethylene of the body, when the particle size increases from 0.15μm to 0.5μm, its color from pale orange (yellowish red) gradually transformed into dark red, dark brown red (purple phase red), the color saturation (c * value) is first increased, then decreased gradually to the maximum value, the brightness (L * value) can change substantially so, for the dry calcined copperas red iron which a c * value L * value and also has a substantially similar circumstances, the yellow iron oxide and synthetic red iron oxide yellow calcination, its needle like particles thereof, which depends not only on the color ratio of the particle size of the shaft, and with a minor axis closely related to the diameter. In the case of substantially constant axial ratio, with the yellow iron oxide particles increases, the pigment color change from pale  stearic acid lemon yellow to orange lemon direction through which the color saturation and brightness of a c * value L * value increases also the first to a maximum value, then decreased gradually. The integrity of the shape of the pigment particles on the optical properties of the grains have a significant impact. The color pigment is a pigment of the performance characteristics of the richest properties, especially a coloring pigment. Nature and color pigments are closely related to its chemical composition, the different chemical composition of each color of the pigment characteristics, but there is a color change within a certain range. Although the same chemical composition, particle size, particle size distribution, the PVC plasticizer  difference in impurity content, etc., will result in differences in shade (pictured), and the colors are extremely sensitive to these factors, but also the human eye is extremely sensitive to the perception of color caused by this paint shade is also difficult to control absolutely the same reason.

Pvc composite stabilizer uses Guinness

The most common cable it uses pvc composite stabilizer is calcium zinc stabilizers composite stabilizer, because the material calcium zinc composite stabilizer is calcium stearate, zinc stearate, antioxidants, hydrotalcite, PE wax Chlorinated paraffin  and other materials, high performance and stability will not be cracked or deformed so on. There is a relatively large tubular objects usually use organic tin and lead salts based pvc composite stabilizer, but a problem needs attention leaded material wishful cause toxic reactions, while tin and lead salts of organic ingredients in favor of tubular objects stable, had to remind everyone in the family life and drinking water pipes must avoid the use of terms. There are also used in our daily life leather products such as shoes, bag, clothes and so they can not be separated using Pvc composite stabilizer in the production process, in which barium zinc stabilizers and stabilizers containing  PVC lubricants cadmium used in series more, mainly because these stabilizers are relatively no odor and transparency better. Like those who have more or plate-type items in the production process of some more of lead salt stabilizer, mainly because of high wear resistance. Although the types of pvc composite stabilizer more choice is too much trouble, but in order to better understand some of the  Stabilizers for pipe application or should a lot of knowledge about the stabilizer, using them will not rush.

Iron oxide for green porcelain firing

Seamless white porcelain body and glaze , warm jade , porcelain and Polyethylene wax  enamel often has its ” ivory “, ” white onion root “, ” lard white” , ” white building “, ” cream ” and the ” velvet white” . Ming Dynasty Dehua porcelain -type is the most famous figure statue , a common Guanyin, Bodhidharma , there Sin cups and vases, four treasures , such as name and imitation bronze incense burner heavy world. To Qing Dynasties , the kilns are not subject to court attention, mostly folk commodity products , often white glaze Fan Qing , in addition to a number of porcelain production also went outside and colorful blue and white porcelain , etc. .
In general, clay and glazes contain some iron ( iron oxide yellow, iron oxide brown , red iron oxide , etc. ) , iron oxide after 1300 degree heat roasting, will be showing different shades of blue , but  zinc stearate if you tire of soil and Glaze iron content in the feed contained less than 0.75% , after baking that will form white porcelain . Therefore , Dehua porcelain kiln firing is not to add white coloring agent to tread the soil or glaze , but use less iron oxide calcined china clay and glazes , and then processed to contain reduce the amount of iron in the high-temperature oxidation reduction , coupled with pure white porcelain transparent glaze can burn create high whiteness porcelain , so in the history of porcelain firing has appeared in the ” blue glaze “, ” sweet white glaze , “” ivory “and other porcelain products. The white porcelain kiln production is not green, or due to containing silicon oxide and hydroxide , glass excellent degree of fetal thin  PVC window stabilizer slices of white enamel products Secheng translucent yellow powder , which is a different place with other white porcelain .

Several factors affect the PVC heat stabilizers transparency

1, the refractive index of the stabilizer
PVC resin, heat stabilizer and 1.52 to 1.55 and a refractive index of  Titanium dioxide rutile visible light or near the same , the better the transparency of PVC products , the transparency is low and vice versa .
2 , stabilizer molecules ( molecules ) of linear length
Heat stabilizer molecule ( or molecules ) linear length of less than 400 ~ 735nm wavelength of visible light refraction less transparency higher , whereas less transparent .
3 , a heat stabilizer in PVC , ” solubility” , i.e., the compatibility of
Compatibility is two or more substances refers to the affinity of each when mixed . Compatibility is good that it is possible to achieve molecular level dispersion . A thermal stabilizer in the molten state has good compatibility with PVC resin . Do not form a two-phase , which is not obvious interface or interface , refraction less , more transparent PVC products . Liquid stabilizer than the corresponding solid metal soaps in PVC compatibility, the length of the linear molecule and smaller , and  Aluminum hydroxide thus the higher the transparency of the PVC .

Good quality lubricant should have the following properties

1 pair of plastic properties should have no adverse effects: as light, heat stability, mechanical properties, electrical properties, transparency, toxicity and no secondary processing and other adverse effects.
2 lubricant itself have excellent light, thermal stability and chemical stability. Poor light stability, are formed in the plastic products after darken light or even decomposition of the lubricant is undesirable; if the lubricant is poor thermal stability and chemical stability, thermal processing, a lubricant darkening affect the color of manufactured goods, even broken down into other substances that may affect processing system to balance the inconvenience. Lubrication of both the outer lead stearate heat stabilizer, thermal stability after the participation of the reaction of stearic acid and lead chloride, lead chloride, and stearic acid in a degree of compatibility with the original hard polyvinyl chloride stearates differences, so it is also a great difference between lubricity, most likely caused by internal and external lubrication imbalance.
3 dispersion. All additives added volume is very limited, inside and outside the lubricant is generally added to the total amount does not exceed 2.5 parts, so they requested that the lubricant must have good dispersion. This, of course cohesion and lubricant compatibility with resin degree related, but also related to the melting point. If the  optical brightener melting point is higher than the plastic processing temperature, the degree of compatibility and poor, such as dibasic lead stearate melting point greater than 280 ℃, barium stearate melting point greater than 225 ℃, is difficult to achieve molecular-level dispersed in the resin melt. If the melting point of the lubricant in the following 120 ℃, high speed mixing in the resin has melted i.e., there may be more uniformly dispersed in the resin.
4 Low volatility: the higher the melting point of the lubricant in general, the lower its volatility. Stearic acid and paraffin cheap, lubrication strong, but its low melting point, more volatile, and thus should be selected higher melting wax, such as microcrystalline wax, the amount should not be too much, otherwise affect its volatile in late lubricating balance, even in its more volatile and condense die, the impact of the mechanical properties of injection molded parts, vacuum  aluminum stearate forming or pore blockage, and the impact of continuous driving time, and even have to shut down for two days to clean up the die.
5 synergies with other additives: if an additive has multiple functions, and of course good, but the premise is the main function of the additive does not affect the characteristics of the condition also known as an adjuvant to achieve a variety of help from agent, or have synergies with other additives and is feasible when the optimum price-performance. GMS such as glyceryl monostearate partially esterified polyhydric is very transparent hard PVC lubricants, while the auxiliary heat stabilizer, antistatic agent antifogging drops; hot metal soaps stabilizers, lubricants, etc. can also commonly used to strengthen the  plastic lubricant role of other additives, if used properly, can be considered with other additives have a positive synergy.
