As the common printing materials of 2513 uv flatbed printing machine, PVC and acrylic are not unfamiliar to us and are often used in our daily life, such as acrylic signs, PVC labels, etc. However, many people think that acrylic, PVC transparent board These two materials are roughly the same, but this is not the case. The two materials are still very different, and there are certain requirements in the field or industry of use. Let's follow the Haibangda editor to learn more about it!
Transparency and environmental protection: The environmental protection of acrylic (PMMA) is better than that of PVC. Some manufacturers' PVC may add plasticizers (plasticizers) to their formulas. harmful to human body;
Transparency: acrylic (PMMA) has better transparency; PVC raw materials are cheaper;
Color: The stability of PVC board is poor, and it is easy to decompose during processing. Generally, the background color will be more yellow than the acrylic of the same color;
Density: The density of the pvc transparent board is 1.38g/cm3, and the density of the acrylic board is 1.1g/cm3; the same size, the pvc board is slightly heavier;
Sound: Use two boards of the same area to drop lightly on the floor or tap with your hands, the sound is clear and crisp is acrylic, and the dull is PVC;
Burning smell: When acrylic burns, the flame is yellow, it smells of alcohol and there is no smoke. When the PVC board burns, the flame is green, there is the smell of hydrochloric acid, and white smoke.
PVC
(1) Polyvinyl chloride (PVC) plastic is a polymer formed by free radical polymerization of vinyl chloride monomer. The English name is polyviny chloride, or PVC for short. PVC can be divided into soft PVC and hard PVC. Among them, hard PVC accounts for about 2/3 of the market, and soft PVC accounts for 1/3.
(2) Hardness PVC board: It has good chemical stability, corrosion resistance, high hardness, high strength, high strength, anti-ultraviolet (aging resistance), fire resistance (self-extinguishing), reliable insulation performance, and smooth surface Flat, non-absorbent, non-deformed, easy to process and so on. This product is an excellent thermoforming material, which can replace some stainless steel and other corrosion-resistant synthetic materials. It is widely used in chemical, petroleum, electroplating, water purification treatment equipment, environmental protection equipment, mining, medicine, electronics, communication and decoration industries. .
(3) PVC transparent board: a high-strength, high-transparency plastic board produced by using advanced imported raw and auxiliary materials. Product colors are white, gem blue, brown, coffee and other varieties. The product has high strength, high transparency, good weather resistance, non-toxic, hygienic and physical properties better than plexiglass. Widely used in equipment guards, interiors, drinking water tanks, liquid level displays, etc.
ACRYLIC
(1) ACRYLIC. It is a chemical material. The chemical name "PMMA" belongs to polyacrylate, commonly known as "specially treated plexiglass". In the application industry, the raw materials of acrylic generally appear in the form of particles, sheets, pipes, etc. Acrylic, also known as plexiglass with special treatment, is a replacement product of plexiglass. The light box made of acrylic has good light transmission performance, pure color, rich color, beautiful and smooth, taking into account both effects of day and night, long service life, and does not affect the use, etc. In addition, acrylic sheets can be perfectly combined with aluminum composite panel profiles, advanced screen printing, etc. to meet the needs of businesses. Acrylic blister is the best form of outdoor advertising to improve the level of business stores and unify corporate image.
(2) Generic term for Acrylic acrylic and methacrylic chemicals. Including monomers, sheets, pellets, resins and composite materials, acrylic sheets are polymerized from methyl methacrylate monomer (MMA), that is, polymethyl methacrylate (PMMA) sheet plexiglass, "organic glass". "Glass" is derived from the trade name "Oroglas" (a PMMA sheet), taken from "Organic Glass" (ie, plexiglass).
(3) Acrylic cast sheet: high molecular weight, excellent stiffness, strength and excellent chemical resistance. This board is characterized by small batch processing, unparalleled flexibility in color system and surface texture effect, and complete product specifications for various special purposes.
(4) Acrylic extruded sheet: Compared with cast sheet, extruded sheet has lower molecular weight and slightly weaker mechanical properties. However, this feature facilitates bending and thermoforming, and when dealing with larger size sheets, it facilitates rapid vacuum forming. At the same time, the thickness tolerance of the extruded sheet is smaller than that of the cast sheet. Due to the large-scale automatic production of extruded boards, it is inconvenient to adjust the color and specifications, so the variety of product specifications is limited to a certain extent.
The above is a summary of the commonly used printing materials for 2513 uv flatbed printing machine, I hope it will help you.
