The principle of ECO-solvent Ink and printing application 2019-11-11
Inkjet printers are inexpensive and have good print quality. They are one of the most popular printers on the market in recent years and are widely used in the inkjet printing industry. Inkjet ink is one of the important elements of inkjet printing technology. At present, green printing has become the common consensus in the industry. The choice of environmentally friendly weak solvent ink as printing ink is of great significance for energy saving and environmental protection. Inkjet ink overview 1. Composition and classification of inkjet ink The composition and function of the inkjet ink are shown in Table 1. According to the type of coloring agent, inkjet ink is mainly divided into dye-based ink and pigment-based ink. The dye-based ink has bright color, soft color and fine particles, but the light fastness is poor, and it is easy to fade and deteriorate. The color of pigment ink is although Not as bright as dye-based inks, but its color fastness can be as long as six months or even a year. Inkjet inks are mainly classified into solvent-based inks, aqueous inks, and uncoated inks and weak solvent inks developed in recent years, depending on the solvent used. 2. The principle of action of weak solvent ink Low-solvent ink, also known as environmentally friendly solvent ink, has the English name ECO-solvent Ink, which is environmentally friendly, uncoated substrate and outdoor weather resistant. The principle of action is that the ink is transferred to the substrate through the nozzle of the micro-piezoelectric print head, wherein the solvent penetrates into the substrate, and as the solvent evaporates, the binder and the colorant in the ink are fixed on the surface

Can superfine silica be used in leather coatings? 2019-09-24
Can superfine silica be used in leather coatings? The so-called extinction, also known as matte light, is the physical uniformity and dispersion of small nano particles in the system, zinc stearate when the light after a period, by these small particles attack continuous reflection, the so-called total reflection, so that the light can not be emitted, so that the appearance looks dark, dull.The action of ultrafine silica depends on the slack strength to a large extent.Arrive good slack effect can choose the rotor must be slack or ball mo machine, three roller machine slack, ultrasonic slack equipment.Slack method and slack equipment selection depends on the consistency of the system.Sometimes it is advisable to use some liquid or some formula material to disperse all the ultrafine silica, and then join the rest of the liquid and other formula materials to adjust the ultrafine silica content to reach the formula requirement.In principle, silica is added with the reduction of the fundamental particle size. However, with the addition of particle fineness, higher shear force is required to reach its thickening effect . Leather finishing agent is polyurethane system, there are two kinds of high gloss (light) and matte, usually according to the light and matte according to a certain ratio of conditioning requirements of gloss, gas silica matte finishing agent to play the role of matte matte matte powder.Due to the serious proportion of the deposited mute powder, it simply presents the sedimentary appearance in the polyurethane system, and independently applies the matting powder ts-100 and tt-600 of degasse gas phase method or toyama fm-14 of Japan, etc. The matting effect can be applied and the deposition appearance can be processed, but the cost is high.At this time, Germany wacke N20 (hydrophilic, 200 square meters/

Electrical insulation and chemical properties of teflon Teflon PTFE has good electrical insulation properties.It has very high resistivity, very low dielectric loss, and because teflon PTFE does not adsorb and absorb water vapor (it does not absorb water and is not infiltrated by water), the surface resistivity is very high even at 100% relative humidity.This property and its flashover resistance make teflon PTFE especially suitable for all kinds of situations requiring insulation.Teflon PTFE is chemically stable, better than any other elastomer.It does not react with all known acids and bases, including the three strong acids and hydrofluoric acids.Teflon PTFE is impervious to moisture and does not dissolve in any known solvent (but can dissolve in molten alkali metals).PTFE is non-flammable and non-toxic, releasing toxic gases only when heated at temperatures above 400 ° c.Due to the inactivity of teflon PTFE, it can only be bonded by special methods.Attention should be paid to the highest working temperature of the adhesive when bonding.Teflon PTFE can be used for high speed cutting with ordinary cutting tools.Different feeding materials (such as graphite, glass fiber, copper powder, etc.) are added in the sintering process of teflon PTFE to obtain modified teflon PTFE, mainly to improve its mechanical and thermal properties.In vacuum technology, teflon PTFE can be used as sealing gaskets, permanent or mobile seals for introduction devices, insulating elements and low-friction motion elements.The application
What are the ingredients and functions of water-based color paste? 2019-09-05
Water-based color paste and water-based coating are developed with the emergence of people's environmental protection needs.Compared with the traditional solvent - based and oil-based solvent - based coatings, the basic characteristics of water - based coatings lay its position in environmentally friendly coatings. The advantages and disadvantages of water-based color paste system and its process type are introduced below.There are two kinds of water-based color paste system: one is high pigment content without resin system;The other is a low pigment content resin (general resin or other single resin) system.Among them, the former pigment has high concentration, strong coloring power, good color performance, compatibility and fluidity, which generally does not cause floating color and hair flowers.The latter pigment concentration is relatively low, but has good coloring power, good color transmissibility, fluidity and viscosity is relatively stable, the system contains resin, compatibility needs to be tested otherwise easy to lead to paint floating color flower.In water-based printing ink and coating, water as solvent and solvent coating compared with organic solvent, water chemistry H ₂ O has a significantly different properties: a water than rich in organic solvent a lot;Water safety, no harm to the human body, no pollution to the environment.The volatile matter of sanshui is water vapor, which will neither increase VOC to produce harmful air pollutants, nor produce atmospheric reaction under the action of light and oxygen, causing secondary air pollution;Four water is non-combustible, unlike solvent - based color paste and solvent - based paint, i
How much do you know about the influence factors of matte powder luster? 2019-08-28
Raise ceaselessly as people living standard, on the one hand consumer feels the bright light coating after becoming film of high burnish glances more serious, harmful to the eye of the person;On the other hand, consumers' aesthetic concept is more and more inclined to be casual, fashionable and personalized.Therefore, when we use matting powder, we should also consider how to use matting powder comprehensively.What are the factors that affect matting powder? First of all, what are the factors affecting gloss and gloss? Light rays cast onto the surface of the object will occur light reflection, the object surface light reflection ability called luster.Different objects on the surface of the gloss is not the same, measuring the amount of light reflection on the surface of the object, called gloss.Gloss is expressed as a percentage.The more shiny a surface is, the more light it reflects and the brighter it is.The degree of gloss is determined by photoelectric gloss instrument.According to the size of glossiness, coating can be divided into light, matt, matt and so on.Classification of paint gloss (take the reflection gloss of 60° (that is, the incidence Angle of light is 60°) as an example) : Matt paint: gloss < 10%; Matt coating: 15 ~ 60% gloss;
There is no more detailed water-based paint thickener than I wrote! 2019-08-19
Many people think that water-based paint thickeners are only for the purpose of reducing costs. Actually, thickeners can make articles thicker, but definitely not to reduce costs. In the production of water-based paints, the viscosity of the emulsion will not be thick. Stable, not conducive to dispersion, and then lead to too low viscosity after coating, thick film sag is serious, so it is very necessary to put thickener in the production or use of water-based paint, but how to choose how to purchase water-based paint Thickener, let Quanxu company Xiaobian tell everyone about it! What is the role of thickeners in coatings? One is to directly increase the overall viscosity of the paint, just like adding more in a class, such as a conventional non-associative thickener, and the other is to connect the ingredients inside the paint, just like the whole class. The hands of the classmates are brought up, such as the hydrophobically modified cellulose ether. What are the hazards of water-based paints that are not thick enough? 1. The emulsion viscosity in the production process is unstable, which is not conducive to dispersion; 2. During storage, the viscosity is too low, causing

The effect of Matting Powder on Coating 2019-08-05
The influence of average particle size of matting powder on coating 1. Relationship between average particle size and transparency: transparency becomes worse with the increase of average particle size.Transparency refers to the good particle size of the powder with the property that the object penetrates through visible light and scatters less. Generally, it should be 1/2 of the wave length of the light in the air, i.e. 0.2-0.4m. Below this value, the powder will lose its ability to scatter light.The powder is usually a mixture of different particle sizes, ranging from 0.01 to 50m. In the system, the smaller the particle size of extinction powder is, the less scattered visible light is, and a large number of incident light rays pass through the extinction powder due to diffraction, so the better the transparency of the system is.However, if the average particle size is too small, fewer particles will play the role of extinction, which cannot play the due role of extinction.When the average particle size is in harmony with the thickness of the coating, the larger the average particle size is, the better the extinction effect of extinction powder is.Therefore, the factors of extinction, transparency and film thickness should be taken into account when selecting matting powder, and the matting powder that meets the requirements should be selected through comparative tests. 2. Relationship between average particle size and anti-sinking ability: in the same system, with the same time of placement, the system with large average particle size has a fast settling rate and is easy to form hard precipitation.The square of particle size is proportional to the settling rate, so the larger the average particle size is, the faster the settling rate will be. 3. Relation between average partic
