Excellent performance of gypsum block

　　1. 石膏砌塊與其他墻體材料尤其是傳統(tǒng)實心粘土磚相比具有以下優(yōu)點:

　　1. Compared with other wall materials, especially traditional solid clay brick, gypsum block has the following advantages:

　　石膏的耐火性能是混凝土的5倍捐凭。石膏砌塊具有比普通紙石膏板更高的耐火性能记舆。1998年鸽捻，我國頒布了《建筑材料燃燒性能分類方法》和《建筑材料可燃性試驗方法》，將石膏制品分類為不可燃產(chǎn)品泽腮。1995年《建筑室內(nèi)裝飾設(shè)計防火規(guī)范》實施后御蒲，石膏墻板產(chǎn)品銷量迅速增長。在德國诊赊，石膏砌塊是DIN4102規(guī)定的a1級不燃建筑材料厚满。石膏砌塊隔墻厚度大于80mm為防火級(防火級f180-a);以上100mm石膏板隔墻屬于高耐火等級(防火等級f180-a)，日本建設(shè)省房管局規(guī)定楚餐，凡使用國庫補貼的建筑斤卒，凡發(fā)生火災(zāi)時，非可燃材料必須用石膏板制成天花板和內(nèi)墻防火板撇扯。

　　The fire resistance of gypsum is five times that of concrete. Gypsum block has higher fire resistance than ordinary paper gypsum board. In 1998, China promulgated "Classification Method for Combustibility of Building Materials" and "Test Method for Combustibility of Building Materials", classifying gypsum products as non-combustible products. After the implementation of Fire Protection Code for Building Interior Decoration Design in 1995, sales of gypsum wallboard products increased rapidly. In Germany, gypsum blocks are class A1 non-combustible building materials specified in DIN4102. The thickness of gypsum block partition wall is more than 80 mm, which is fire-proof grade (fire-proof grade f180-a). The above 100 mm gypsum board partition wall belongs to high fire-proof grade (fire-proof grade f180-a). The Ministry of Construction and Housing Administration of Japan stipulates that all buildings subsidized by the State Treasury must be made of non-combustible materials into ceilings and interior wall fire-proof panels in case of fire.

　　此外囚誓，由于兩種水石膏在火災(zāi)高溫狀態(tài)下釋放水分，其含量高達21%见撵。如果墻體為80mm厚的石膏砌塊墻启孔，每平方米火災(zāi)燃燒時應(yīng)蒸發(fā)約15kg的水，墻體可進一步升溫舟到。一般情況下，1kg結(jié)晶水需要126KJ左右的熱量臀嘱。40平方米的辦公室相當于1t的水蒸發(fā)章理，這將消耗大量的熱量所硅。其他非石膏墻體材料則沒有這種特性。

　　In addition, because the two kinds of water gypsum release water at high temperature in fire, the content of water gypsum is as high as 21%. If the wall is 80 mm thick gypsum block wall, about 15 kg of water should be evaporated per square meter when the fire burns, and the wall can be further warmed up. Generally, 1 kg crystalline water needs about 126 KJ of heat. 40 square meters of office is equivalent to 1 ton of water evaporation, which will consume a lot of heat. Other non-gypsum wall materials do not have this characteristic.

　　2杂蒙、具有良好的絕緣和隔音特性

　　2. Good insulation and sound insulation

　　1厘米厚石膏層的隔熱性能相當于3厘米厚的磚層营稼、4厘米厚的灰漿灰泥或5厘米厚的混凝土房屋的隔熱性能。

　　The thermal insulation performance of 1 cm thick gypsum layer is equivalent to that of 3 cm thick brick layer, 4 cm thick mortar or 5 cm thick concrete house.

　　當普通外墻磚厚度為370mm時台腥，傳熱系數(shù)為1.34kcal /M2?H ?如果采用200mm厚石膏板墻體宏赘，傳熱系數(shù)為0.17Kcal/M2?H ?℃時，節(jié)能60%黎侈，一般80mm厚石膏砌塊相當于240mm厚實心磚的保溫能力察署。

　　When the thickness of ordinary exterior wall brick is 370 mm, the heat transfer coefficient is 1.34 kcal/M2?H? If 200 mm thick gypsum board wall is adopted, the heat transfer coefficient is 0.17 Kcal/M2?H????? C, the energy saving is 60%, and the heat preservation capacity of 80 mm thick gypsum block is equivalent to that of 240 mm thick solid brick.

　　此外，以100mm厚石膏砌塊墻體為例峻汉，其隔聲效果達到36-38db贴汪，這是其他同類型、同厚度建筑材料難以達到的休吠。脫硫石膏粉空心砌塊的隔聲價值扳埂，尤其是低頻隔聲價值雖然有所降低，但仍能滿足隔聲要求瘤礁。在石膏砌塊中加入膨脹珍珠巖阳懂、陶粒等輕質(zhì)集合體，或發(fā)泡石膏漿柜思，或采用空腔結(jié)構(gòu)和吸聲材料等岩调，可提高砌塊的保溫隔聲性能。

　　In addition, taking 100 mm thick gypsum block wall as an example, its sound insulation effect reaches 36-38 db, which is difficult to achieve by other similar building materials with the same thickness. Desulfurization gypsum powder hollow block sound insulation value, especially low-frequency sound insulation value, although reduced, but still can meet the requirements of sound insulation. Adding light aggregates such as expanded perlite and ceramsite, or foaming gypsum slurry, or using cavity structure and sound absorbing materials in gypsum blocks can improve the insulation and sound insulation performance of the blocks.

　　3那辰、墻體較輕拳鹉，抗沖擊性好

　　3. The wall is lighter and has good impact resistance.

　　雙石膏粘土固體磚,例如,半磚墻296重㎏/㎡,一堵磚墻的重量524㎏/㎡,和不同的固體抹石膏砌塊墻,大約72㎏/㎡80毫米厚,100毫米厚約90㎏/㎡,粘土實心磚的1/3重量墻- 1/4。

　　Double gypsum clay solid brick, for example, half brick wall 296 heavy /, a brick wall weight 524 /, and different solid plaster block walls, about 72 / 80 mm thick, 100 mm thick about 90 /, clay solid brick 1/3 weight wall - 1/4.

　　由此可見绑燃，具有優(yōu)良特性的石膏砌塊能夠很好地滿足我們的發(fā)展需求乍之，這類環(huán)保節(jié)能產(chǎn)品值得我們的信賴和開發(fā)是很重要的。

　　Therefore, gypsum blocks with excellent characteristics can well meet our development needs. It is very important for us to trust and develop this kind of environmental protection and energy saving products.
