GRG(Glass Fiber Reinforced Gypsum)玻璃纖維增強(qiáng)石膏制品
GRG是玻璃纖維增強(qiáng)石膏制品，它是一種經(jīng)礦物纖維預(yù)制增強(qiáng)的特殊改良石膏裝飾材料，造型的無局限可塑性使其成為個性化建筑室內(nèi)設(shè)計師的首選，它獨特的材料成型構(gòu)成方工足以抵御外部環(huán)境造成的破損、變形和開裂，達(dá)到最佳裝飾效果。
設(shè)計造形豐富任意采用預(yù)鑄式加工工藝的 GRG產(chǎn)品可以定制單曲面、雙曲面、多曲面的三維覆面各種幾何形狀、鏤空花紋、浮雕圖案等任意復(fù)雜的藝術(shù)造型，充分發(fā)揮設(shè)計師想象的空間。
強(qiáng)度高、質(zhì)量輕GRG產(chǎn)品的彎曲強(qiáng)度達(dá)到Mpa20-25（ASTMD790-2002測試方式）。
拉伸強(qiáng)度達(dá)到Mpa8-15（ASTMD256-2002測試方 式，且6-8mm厚的標(biāo)準(zhǔn)板重量僅為6-9kg/m2，能滿足大板塊吊頂分割需求的同時，減輕主體重量及構(gòu)件負(fù)荷。
不變形、不開裂出于主材石膏熱膨脹系數(shù)低、干濕收縮率小于0.01%，使GRG產(chǎn)品不受環(huán)境冷、熱、干、濕變形影響，性能穩(wěn)定不變形。獨特布纖加工工藝使產(chǎn)品不龜裂使用壽命長。
聲學(xué)反射性能GRG具有良好的聲波反射性能，經(jīng)同濟(jì)聲學(xué)研究所測試：30mm 單片重量48kg的GRG板，聲學(xué)反射系數(shù)R≥0.97，符合專業(yè)聲 學(xué)反射要求，適用于大劇院、音樂廳等聲學(xué)原聲廳。
它主要以壁薄、質(zhì)輕、強(qiáng)度高及不燃性（級防火材料），并可對室內(nèi)環(huán)境的濕度進(jìn)行調(diào)節(jié)，以其能達(dá)到舒適的生活環(huán)境。其高強(qiáng)度、高硬度和很好的柔韌性，能滿足最終被制成任意造型
防火、防潮、環(huán)保，防火性能阻燃性能達(dá)到級，按GB8624-2012《建筑材料及制品燃燒性能分級》標(biāo)準(zhǔn)。環(huán)保性能放射性核素限量達(dá)到A 級，按GB6566-2010《建筑材料放射性核素限量》標(biāo)準(zhǔn)。防潮性能GRG材料均為無機(jī)材料，不會發(fā)生霉變發(fā)黃現(xiàn)象。
GRG is glass fiber reinforced gypsum products, it is a special modified gypsum decorative
material reinforced by the mineral fiber prefabrication, which makes it become the first
choice of personalized architectural interior designer, and its unique material forming way
is enough to resist the damage, deformation and cracking caused by external environment,
and achieves perfect interior decoration effect.
Design-shaped rich arbitrary-the use of pre-cast processing technology GRG products can be customized single,
double curved, curved three-dimensional covering a variety of geometric shapes, hollow patterns, relief patterns,
such as any complex art model ing, give full play to the designers imagined space.
The flexural st rength of GRG products wi th high st rength and light qual i ty is mpa20-25 (astmd790-2002 test mode) .
Tensile strength reached mpa8-15 (astmd256-2002 test method, and 6-8mm thickness of the standard board weight is
only 6-9kg/m2, can meet the needs of large plate cei l ing segment, whi le reducing the main weight and component load.
No deformation, no cracking-for the main material gypsum thermal expansion coefficient is low, wet and dry shrinkage
rate is less than 0.01%, so that GRG products are not af fected by the envi ronment cold, hot, dry, wet deformat ion, stable
performance and no deformation. Unique fiber processing technology so that products do not crack long service life.
Acoustic reflection Per formance GRG has good sound wave ref lect ion per formance, through the Tongji Institute of
Acoustics test: 30mm single piece weight 48kg GRG board, acoust ic ref lectance coef f icient r≥0.97, in line wi th the
professional acoustic reflection requirements, applicable to large theaters, concert halls and other acoustical acoustic
acoustic Hall.
I t is mainly in thin wal l , l ight weight, high st rength and non-f lammable (A-class fire-retardant material), and can be
adjusted to indoor envi ronment humidi ty, in order to achieve a comfor table living envi ronment . Its high strength, high
hardness and good flexibi l i ty, can meet the final form of arbi t rary shape
Fire, moisture, environmental protection, fire performance-flame retardant performance reached a level, according to
GB8624-2012 "Building materials and products combustion performance grading" standard. Environmental
performance-radionuclide limit reached a level, according to GB6566-2010 "Building materials radionuclide limit"
standard. Moisture-proof properties of GRG materials are inorganic materials, will not occur yellowing phenomenon.
