Q:What are the differences between digital textile printing ink and printing ink?
3. acid ink:Suitable for jet printing of silk, wool and nylon;4. coating ink:Suitable for direct printing of all textiles.
Q:Which is better, ceramic fiber or spray velvet?
With the blowing of thrown silk cotton is two kinds of refractory ceramic fiber cotton cotton in the market at present, according to different production process is defined. Because of the different process, the characteristics of the two kinds of fire-resistant cotton are also different. According to different characteristics, they are applied in different heat insulation fields respectively. Ceramic fiber cotton, also known as aluminum silicate fiber cotton, its main purpose is to use other forms of refractory products, production and processing of raw materials.
Q:What are the uses of ceramic fiber blankets?
Ceramic fiber blanket is mainly used for high temperature, tough, self bearing high strength of the place, but also used for high airflow speed, mechanical destruction of large places. Ceramic fiber blanket can be used in these occasions.
Q:Is everybody's ceramic fiber cloth poisonous?
With aluminum, zinc and other non-ferrous molten metal erosion capacity. Excellent high temperature strength. The bottom heat conductivity makes the product have good heat insulation performance. Excellent electrical insulation performance. Non-toxic, harmless, no adverse effects on the environment, excellent tensile properties.
Q:What are the man-made fibers polluting the environment?
Fibers are roughly divided into natural fibers, man-made fibers, and synthetic fibers[natural fiber] refers to the natural growth or formation of fiber, including plant fiber (natural cellulose fiber), animal fibers (natural protein fiber) and mineral fiber. Plant fibers include: seed fiber, phloem fiber, leaf fiber, and fruit fiber. Seed fiber is the unicellular fiber that grows from the epidermal cells of some plant seeds. Such as cotton, kapok. Bast fiber is a single fiber or process fiber obtained from the phloem of some plants. Such as: linen, ramie, jute. Leaf fiber is the process fiber obtained from the leaves or sheaths of some plants. Such as: sisal, abaca. Fruit fiber is the fiber obtained from the fruit of some plants. Coconut fiber. An animal fiber (natural protein fiber) that includes hair, fiber, and gland fibers. Hair follicles: fibers of the hair follicles that have multicellular structures and are composed of keratin. Such as: wool, cashmere, camel hair, rabbit hair, Ma Haimao. Silk fibers: fibers formed from the glands of some insects, especially those produced by lepidopteran larvae, and fibers formed by secretions of some mollusks. Such as: silk.
Q:Can ceramic fibers be spun?
Ceramic fiber itself is relatively brittle, silk is relatively short, spinnability, but after adding viscose (differential polyester glass fiber, even pulp) as the heart can be spun,
Q:The difference between ceramic fiber cloth and ceramic fiber paper
1. appearance. The ceramic fiber cloth has an obvious grid like appearance, and the ceramic fiber paper is very few or even mesh like.2. density. The density of ceramic fiber paper is greater than that of ceramic fiber cloth.3. thickness. Ceramic fiber paper, the thinnest can do 0.5mm, ceramic fiber paper can not do so thin, generally thin, there are also 2mm.4. stand erect. Ceramic fiber paper can be like in our life that can be placed on the A4 paper, mold, stand up. Ceramic fiber cloth is like the fabric used in our 5. lives. It's soft and doesn't stand upright.6. tear resistance. The toughness of the ceramic fiber paper is not as good as that of the ceramic fiber cloth.
Q:Is aluminum silicate fiber completely insulated from heat transfer?
Fire-resistant insulation layer is used to make ceramic fiber module insulation, thermal insulation thickness of four hundred mm, the ceramic fiber blanket double extrusion, ceramic fiber module in parallel sorting, the trolley furnace wall temperature to plate temperature rise of forty-five degrees, which is almost a best isolation effect.
Q:Does the component of textiles contain 70% acrylic? Does it hurt the body?
Acrylic may sound strange, because it is a new word that has appeared on the mainland in the last two years. It was not until 2002 that the advertising industry, furniture industry and handicraft industry were gradually understood by a few. "Acrylic" is a transliteration of foreign words, English is ACRYLIC, it is a chemical material. The chemical name is called "PMMA", which belongs to propylene alcohol, commonly known as "specially treated organic glass". In the application industry, its raw materials usually appear in the form of particles, plates, pipes and so on.
Q:What is the function of (ceramic) ceramic powder?
In the process of porcelain fused to metal (PFM), the powder material used for sintering and making ceramic restoration is made. There are long stone and alumina ceramic powder, as well as a variety of crystal reinforced porcelain powder, high temperature porcelain powder and low temperature porcelain powder.
