GRG: 中文全稱:預鑄式玻璃纖維增強石膏成型品 GRG 英文名:GlassFiber Reinforced Gypsum GRG是預鑄式玻璃纖維加強石膏板,它是一種特殊改良纖維石膏裝飾材料,造型的隨意性使其成為要求個性化的建筑師的,它獨特的材料構成方式足以抵御外部環境造成的破損、變形和開裂。 GRG產品是采用GRG專用石膏—超細結晶石膏(改良的ɑ石膏)為基料與專用連續剛性的增強玻璃纖維、我司開發的專有添加劑(符合英國原廠的添加劑要求),在模具上經過特殊工藝層壓而成的預鑄式新型裝飾材料,在綜合性能上達到了英國的質量標準。GRG產品是采用高密度Alpha石膏粉、增強玻璃纖維,以及一些微量環保添加劑制成的預鑄式新型裝飾材料,產品表面光潔平滑呈白色,材質表面光潔、細膩,白度達到90%以上,并且可以和各種涂料及面飾材料良好地粘結,形成佳的裝飾效果、環保安全不含任何有害元素。此種材料可制成各種平面板、各種功能型產品及各種藝術造型,是目前國際上建筑材料裝飾界流行的更新換代產品。正常情況下,建筑設計師們經常會推薦應用在業建筑為抵抗高的沖擊而增加其穩定性的吊頂為主。此外,由于GRG材料的防水性能和良好的聲學性能,尤其適用于頻繁的清潔洗滌和聲音傳輸的地方,像學校、醫院、商場、劇院等場所。 GRG性能: 選形豐富任意―采用預鑄式加工工藝的GRG產品可以定制單曲面、雙曲面、三維覆面各種幾何形狀、鏤空花紋、浮雕圖案等任意藝術造型,充分發揮設計。 強度高、質量輕―GRG產品的彎曲強度達到Mpa20-25(ASTMD790-2002測試方式)。拉伸強度達到Mpa8-15(ASTMD256-2002測試方式,且6-8mm厚的標準板重量僅為6-9kg/m2,能滿足大板塊吊頂分割需求的同時,減輕主體重量及構件負荷。 不變形、不開裂―出于主材石膏熱膨脹系數低、干濕收縮率小于0.01%,使GRG產品不受環境冷、熱、干、濕變形影響,性能穩定不變形。獨特布纖加工工藝使產品不龜裂使用壽命長。 聲學反射性能―GRG具有良好的聲波反射性能,經同濟聲學研究所測試:30mm單片重量48kg的GRG板,聲學反射系數R≥0.97,符合聲學反射要求,適用于大劇院、音樂廳等聲學原聲廳。 它主要以壁薄、質輕、強度高及不燃性(A1級防火材料),并可對室內環境的濕度進行調節,以其能達到舒適的生活環境。其高強度、高硬度和很好的柔韌性,能滿足終被制成任意造型、大規格及有質感效果的產品。在120℃高溫下存放72小時無變形。 Choose any-using the form rich cast type processing technology of the product can be customized GRG single curved surface and hyperboloid, 3 d by various geometric shape, face hollow out decorative pattern, such as design of art form any relief, give full play to the design. High strength, light quality-GRG products to the bending strength Mpa20-25 (ASTMD790-2002 test means). Tensile strength to Mpa8-15 (ASTMD256-2002 testing methods, and 6-8 mm thick standards board weight only 6-9 kg/m2, can satisfy the plate condole top division at the same time, reduce demand and main body weight component load. Deformation, cracks-out of material thermal expansion coefficient, dry and wet plaster low shrinkage of less than 0.01%, make GRG products do not suffer environmental cold, hot, dry, wet deformation, performance stability deformation. Unique cloth fiber processing technology make products not cracked long service life. Acoustic reflection GRG has good performance-the sound waves reflected performance, the institute of acoustics tongji test: 30 mm 48 kg weight of single chip GRG board, acoustic reflection coefficient R quartile 0.97, conform to the professional requirements and acoustic reflection, and is suitable for the concert hall, the grand theatre, acoustic acoustic hall. It mainly wall thin, qualitative light, intensity tall and incombustible (A1 level fire materials), and can be used for indoor environment humidity on the adjustment, with its can achieve the comfortable life environment. The high strength, high hardness and good flexibility, can satisfy the eventually be made into any shape, large size and has the effect of simple sense products. In 120Degrees Celsius high temperature store 72 hours without distortion.
