The role of acrylic acid and use
Acrylic acid and its series products, mainly is the ester, rapid development in recent years. Such as ethylene, propylene, vinyl chloride, such acrylonitrile, develop to become important high polymer chemistry industrial raw material. Acrylic acid and its ester as polymers monomers, the world production has more than t, and made by the polymer and copolymer (mainly emulsion type resin) yield nearly 5 million t. The resin application in coatings, plastic, textile, leather, paper, building materials, packaging materials, etc and numerous departments. Acrylic acid and its ester available for organic synthesis and polymer synthesis, and the vast majority are used for the latter, and is more with other monomers, such as ethylene acetate, styrene, methyl methacrylate (mma) of copolymerization, all kinds of the performance of synthetic resin, functional polymer material and all kinds of additives, etc. Main applications: (1) the warp size and methyl methacrylate by acrylic acid, acrylic acid ethyl ester, acrylonitrile, ammonium polyacrylic acid based on raw materials such as the warp size, polyvinyl alcohol (pva) than the size of desizing capacity, save the starch. (2) with acrylic adhesive, acrylic, acrylic acid methyl ethyl ester, acrylic-2-ethyl ester copolymerization has latex, can make electrostatic flocking, the hair of the adhesives, the firm sex and feel good. (3) water thickener use bingxisuan and acrylic acid ethyl ester copolymer made into high molecular weight powder. Can be thickener, used in oil field, every tons of product can yield increase by 500 t crude oil, oil production to old Wells effect is good. (4) paper finishing agent, with acrylic butyl acrylic, acrylic-2-ethyl acetate, styrene has four yuan copolymerization latex paint for glossy paper, not the color yellow, printing performance is good, not sticky roller, than butyl benzene latex good can save dry and cool meat. (5) polyacrylic acid salts use acrylic acid to produce various polyacrylic acid salt products (such as the ammonium salt, sodium salt, potassium, aluminum salt, nickel salt, etc.). Used as a NingJiJi, water quality treatment agent, dispersant, thickener, food BaoXianJi acid and alkali resistant desiccant, softener, etc. Various kinds of polymer additives, as oil drilling mud thinners XY27 /, XY28, oilfield drilling mud drop water loss, FA368 FA367 etc.

Acrylic understanding
Printing often hear of acrylic products acrylic plate, acrylic, plastic pellets, acrylic light boxes, signs, acrylic bathtub,acrylic artificial marble, acrylic resin, acrylic (latex) paint, etc. products, a wide range. In fact, the Department of acrylic products, general market consumers often acrylic pellets, sheet metal or resin and other raw materials through avariety of different processing methods, and with a variety of different materials and functions of parts to beassembled from the acrylic products. As for the commonly heard of acrylic fiber, acrylic, cotton, acrylic yarn, acrylicdragon and other means by acrylic polymer made of man-made fibers, not related with the acrylic products. Among them, commonly known as acrylic plate of polymethyl methacrylate Polymeric Methyl Methacrylate (PMMA) plates, it is'the methyl methacrylate monomer of methyl Methacrylate (MMA)' polymerization. Extrusion is made through thecrowded board machine or by acrylic pellets. Previous acrylic panels are commonly known as plexiglass. Theplexiglass derived from the English Organic Glass, means that organic compounds of the MMA made of PMMA sheet,transparency and light transmission as glass. But in recent years due to the sheet of transparent plastic such as PS, the PC or made by the poor quality of the recovery of MMA are collectively referred to as plexiglass. Demandsegmentation purposes, the special will be made in the pure material of high quality MMA PMMA plate shall be acrylic plate names of the plexiglass plate and in general the segment.
PMMA is a polymer of acrylic acid and its esters polymerization collectively referred to as acrylic resin, the corresponding plastic collectively referred to as the polyacrylic acid plastic, which is the most widely used poly methylacrylic ester methyl application. Symbols of poly (methyl methacrylate) PMMA, commonly known as Plexiglas, is the most excellent quality so far synthetic transparent material.
PMMA has a lightweight, inexpensive, easy to shape and so on.Forming method, casting, injection molding,machining, acrylic thermoforming. Injection molding, can be mass-produced, the process is simple, low cost.Therefore, it is more widely applied, it is widely used in instrumentation parts, car lights, optical lenses, transparentpipeline.
