GRG： 中文全稱：預(yù)鑄式玻璃纖維增強(qiáng)石膏成型品 　　 GRG 英文名：GlassFiber Reinforced Gypsum GRG是預(yù)鑄式玻璃纖維加強(qiáng)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(gè)性化的建筑師的，它獨(dú)特的材料構(gòu)成方式足以抵御外部環(huán)境造成的破損、變形和開裂。 GRG產(chǎn)品是采用GRG專用石膏—超細(xì)結(jié)晶石膏（改良的ɑ石膏）為基料與專用連續(xù)剛性的增強(qiáng)玻璃纖維、我司開發(fā)的專有添加劑（符合英國(guó)原廠的添加劑要求），在模具上經(jīng)過特殊工藝層壓而成的預(yù)鑄式新型裝飾材料，在綜合性能上達(dá)到了英國(guó)的質(zhì)量標(biāo)準(zhǔn)。GRG產(chǎn)品是采用高密度Alpha石膏粉、增強(qiáng)玻璃纖維，以及一些微量環(huán)保添加劑制成的預(yù)鑄式新型裝飾材料，產(chǎn)品表面光潔平滑呈白色，材質(zhì)表面光潔、細(xì)膩，白度達(dá)到90%以上，并且可以和各種涂料及面飾材料良好地粘結(jié)，形成佳的裝飾效果、環(huán)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(chǎn)品及各種藝術(shù)造型，是目前國(guó)際上建筑材料裝飾界流行的更新?lián)Q代產(chǎn)品。正常情況下，建筑設(shè)計(jì)師們經(jīng)常會(huì)推薦應(yīng)用在業(yè)建筑為抵抗高的沖擊而增加其穩(wěn)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(xué)性能，尤其適用于頻繁的清潔洗滌和聲音傳輸?shù)牡胤剑駥W(xué)校、醫(yī)院、商場(chǎng)、劇院等場(chǎng)所。 GRG性能： 選形豐富任意―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、三維覆面各種幾何形狀、鏤空花紋、浮雕圖案等任意藝術(shù)造型，充分發(fā)揮設(shè)計(jì)。 　　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(cè)試方式）。拉伸強(qiáng)度達(dá)到Mpa8-15（ASTMD256-2002測(cè)試方式，且6-8mm厚的標(biāo)準(zhǔn)板重量?jī)H為6-9kg/m2，能滿足大板塊吊頂分割需求的同時(shí)，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(dú)特布纖加工工藝使產(chǎn)品不龜裂使用壽命長(zhǎng)。 　　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(cè)試：30mm單片重量48kg的GRG板，聲學(xué)反射系數(shù)R≥0.97，符合聲學(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（A1級(jí)防火材料），并可對(duì)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，能滿足終被制成任意造型、大規(guī)格及有質(zhì)感效果的產(chǎn)品。在120℃高溫下存放72小時(shí)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.
