essing of surface will appear chapped etc.. Hardness is one of the qualityevaluation of acryl plate rigid index. Our company product import castable acrylic sheet with the current domestic same product the highest hardness index. The averageDaluoshi hardness of 89 degrees.
2: thickness tolerance control sheet thickness tolerance is an important manifestation ofthe quality management and production technology. To control the import castableacrylic board thickness tolerance within +0.2mm.
3 transparency / whiteness:
Production process to follow up and modernization strict material selection, formula withthe advanced plate, ensure excellent transparency and white. Flame polishing crystal clear.
The matters needing attention
1 acrylic plate can not be with other organic solvent with save a place, more can not contact with organic solvent
2 in the transport process, not the surface protective films or scratch paper
3 cannot be used in a temperature exceeding 85 DEG C environment
4 clean the acrylic sheet only use 1% of the soap water, dipped in soapy water with a soft cotton cloth, not available hard or dry rub, otherwise easily be scraped surface
5 acrylic plate cold and heat expansion coefficient greatly, due to temperature changesshould be considered for reserved expansion gap
Acrylic plate and the organic glass
"Organic glass" from English Organic Glass. In recent years in some areas will platemade of transparent plastic all referred to as organic glass, actually this is wrong,acrylic refers to pure PMMA (PMMA) material, and the PMMA sheet called acrylic plate.
Characteristics and advantages of acrylic plate
Acrylic high transparency, light transmission rate of 92%, a "plastic crystal" reputation.And has excellent weather resistance, especially in outdoor applications, the other plastics of the crown, and with good surface hardness and luster, processing and plasticity, can be made into various shapes needed and products. Other kinds of rich color plate type (including the translucent shade guide), another characteristic is the plate can still maintain a high level of transparency.
Acrylic history
Acrylic (ACRYLIC), common name the special treatment of organic glass. Research and development of acrylic, dating back more than one hundred years of history. In 1872 the polymerization of acrylic acid resistance was found in 1880; methyl acrylic acidpolymerization known; synthesis of propylene poly propionic acid lipid completed in 1901; in 1927 the use of the above synthesis attempts to industrialized manufacturemethyl acid ester; in 1937 the successful development of industrial manufacturing, thus entering scale manufacturing. During World War II because acrylic with high toughnessand excellent light transmittance, first of all, be applied to aircraft windshield, tank drivercab vision mirror. In 1948 the first world only acrylic bathtub was born, marks theapplication of acrylics entered a new milepost.
The application of acrylic
PMMA has the advantages of light weight, low cost, the advantages of easy moldingetc.. It's a casting molding method, injection molding, machining, heat molding etc..Especially in injection molding, can be mass production, has the advantages of simple process, low cost. Therefore, it is used more and more widely, it is currently widely used instrument parts, auto lamp, optical lenses, transparent pipes etc..
Acrylic is a new material best following the ceramic sanitary ware can be made after the.Compared with the traditional ceramic materials, acrylic high brightness incomparableexcept outside, still have the following advantages: good toughness, is not easy to damage; repair is strong, can be used as long as the soft foam dipped in toothpaste willware wiped clean; the texture is soft, the winter is not cold feeling; bright color, can meet the needs of different grade the pursuit of individuality. Acrylic production of basin,bathtub, toilet, not only exquisite style, durable, and has environmental effects, radiation and the radiation level of the body's own bone not much difference between. Acrylic ware first appeared in the USA, now occupies the entire international market more than 70%.
Acrylic production due to difficult, high cost, so there is a lot of low qualityinexpensive substitutes market. These substitutes also known as "acrylic", is actually the common organic plate or composite board (also known as the sandwich board). Plexiglass plate with ordinary common organic materials plus pigments cast from cracking, the surface hardness is low, easy to fade, with fine sand and polished finish and difference. Only the surface of a thin plate layer
Acrylic, middle is the ABS plastic, easy to use by the thermal expansion and contraction of the delamination. True or false acrylic, can from the plate section of the subtle effects of color and polishing to identify
1 Application Architecture: windows, insulation windows, lighting cover, a telephone booth
2 application: light boxes, signs, advertising signs, display rack
3: train traffic applications, vehicle doors and windows
4 medical applications: baby incubators, various operation medical apparatus people activities: bathroom facilities, handicrafts, cosmet
