Acrylic Risers Glass alternative material
Polymethylmethacrylate (referred to as PMMA, English Acrylic), also known as acrylic or plexiglass, in Hong Kong and more known as Aga glue, with high transparency, low price, easy machining, etc., is often regular Use of glass instead of material. The monomer of polymethylmethacrylate is methyl methacrylate (MMA, acrylic monomer).
Acrylic chemical called polymethyl methacrylate, at room temperature is non-toxic, the taste of the cut when the ester-specific flavor, often smell will make people dizzy, is toxic but not highly toxic. When the temperature exceeds 130-140 ° C, the chemical reaction will cause the acrylic to burn and produce harmful gases.
In order to better use acrylic products, we should note the following:
1 can not be stored with other organic solvents, but can not contact with organic solvents
2 During transport, the surface protective film or protective paper can not be scratched
3 can not be used in environments where the temperature exceeds 85 degrees Celsius. Of course, when the temperature exceeds 130-140 ° C, in the case of aerobic on another matter, it will play a chemical reaction. When we learned high school chemistry, so that the probability of burning completely burning acrylic, so basically acrylic combustion will produce harmful gases. I have this experience. Our factory is specialized in the production of acrylic products, acrylic display stand, and sometimes will use the laser engraving machine, each time through the laser engraving machine carved acrylic, always smell a pungent taste. This is the acrylic gas is not full combustion of harmful gases. Therefore, when using a laser engraving machine, the doors and windows should be opened and kept in a ventilated state. Especially in winter, do not shut the doors and windows, should not open air conditioning.
4 cleaning acrylic products only 1% of soapy water, with soft cotton cloth dipped in soap and water, can not be used hard or dry rub, otherwise the surface is easy to be scratched. Acrylic (methyl methacrylate) in addition to polymerization can be PMMA and acrylic sheet for the downstream processing plant made of finished products, but also and a variety of other different monomer raw materials from the copolymer (Co-polymers ), The liquid type, made of various uses of the resin, used in the following products:
· PVC modifier (MBS): used to improve the impact resistance of PVC and processing performance.
Paint: acrylic resin paint can be divided into oily, water-based two categories, used for indoor and outdoor architectural paint and metal, wood, plastic and other industrial paint.
Adhesive: can be divided into two types of pressure and non-pressure. Pressure-sensitive acrylic adhesive can be used for labels, tape, decorative film, protective materials, surgical tape, pressure-sensitive wallpaper, carpets, N times sticky notes paper, shoes and so on. Non-pressure-sensitive adhesive can be used for paper, fabric fit, flocking, building with the paste.
· Textile processing agent: can be used for the production of non-woven, flocking, printing and dyeing, paste and finishing purposes.
· Paper light treatment agent and paper dispersant: UV hardening resin polishing agent for the bulk, can improve the surface gloss of printed matter, increase the appearance and a sense of high, increase the surface of the wear resistance and scratch resistance.
