发泡水泥保温板的性能特点介绍
作者:admin 来源:本站 发布时间:2018-11-07 18:42:55 浏览次数:268
2.1 容重轻。每立方米发泡水泥板重200~300kg,仅是水泥砂浆的六分之一。40mm厚发泡水泥板每平方米重量8kg,300×300×40mm的保温板外表面积0.09m2,由于外表有2mm大小的孔,使外表面积放大30%以上,一块保温板实践面积应该为0.117m2。依据粘结砂浆粘结强度大于0.1MPa计算,即每cm2能够有1kg粘结力,而300×300mm的板实践粘结力可达1170kg。
2.1 light weight. Each cubic meter of foamed cement slab weighs 200 to 300kg, only 1/6 of cement mortar. The outer surface area of 40 mm thick foamed cement board is 0.09 m2, which is 8 kg/m2 by weight and 300 *300 *40 mm by weight. Because of the 2 mm hole in the outer surface, the outer surface area is enlarged by more than 30%. The practical area of a thermal insulation board should be 0.117 m2. According to the calculation of bonding strength of bonded mortar greater than 0.1 MPa, that is, 1 kg bonding force per cm2 and 1 170 kg bonding force per 300 mm slab in practice.
2.2 导热系数低。硅酸盐水泥发泡板完成了多孔的闭孔构造使导热系数比混凝土任何砂浆都要低,经实践检测在0.08~0.066W(m.k),完整能到达江苏65%的节能指标请求。
2.2 low thermal conductivity. Portland cement foam board has completed the porous closed-cell structure, which makes the thermal conductivity lower than any concrete mortar. Practical testing shows that it can reach 65% of the energy-saving index requirements in Jiangsu Province at 0.08-0.066W (m.k).

2.3 力学性能优良。抗压强度到达0.4~0.5MPa,发泡水泥板中运用特种纤维,增加了发泡水泥板的抗压强度,经国度专业检测机构检验,抗弯毁坏荷载为可承重自重3倍以上(国度规范为1.5倍),抗压强度为5/MPa以上(国度规范为3.5/MPa),吊挂力为1500/N以上(国度规范为1000/N)。普通的保温砂浆、有机发泡保温板的抗拉强度约为0.1MPa,发泡水泥保温板的抗拉强度能到达0.13MPa。

2.3 excellent mechanical properties. The compressive strength reaches 0.4-0.5 MPa. The use of special fibers in the foamed cement board increases the compressive strength of the foamed cement board. The bending damage load is more than three times of the load-bearing weight (1.5 times of the national code), the compressive strength is more than 5/MPa (3.5/MPa of the national code), and the hanging force is more than 1500/N. (national standard is 1000/N). The tensile strength of ordinary insulation mortar and organic foamed insulation board is about 0.1 MPa, and that of foamed cement insulation board can reach 0.13 MPa.
2.4 吸水率低。正轨的达标企业经过水泥添加剂将水泥中90%的粗孔改动为细毛细孔,由于水分子外表张力作用无法进入该毛细孔内,能完成发泡水泥保温板体积吸水率在10%以下,能够完成更好的保温效果。
2.4 low water absorption. Orthogonal track enterprises change 90% of the coarse pore into fine pore through cement additives. Because of the external tension of water molecules, they can not enter the capillary pore, and the volume water absorption of foamed cement insulation board is less than 10%, which can achieve better thermal insulation effect.
2.5 防火、抗熄灭性能好。由于硅酸盐水泥自身是无机不燃材料,配方中又没有任何有机类纤维和添加剂,所以制成的发泡板在高温1000℃都不燃,到达A1级防火等级;而有机保温材料普通只能做到B1等级(分开火源自熄灭)。发泡水泥保温板抗熄灭性能有两个方面性能:⑴避免火焰扩散的才能,即能阻挠部分火焰扩散而自行熄灭;⑵材料自身的绝热性能好,即便在材料一侧熄灭,另一侧的温度不会升得较高而惹起火灾扩展。与聚苯乙烯泡沫、聚氨酯泡沫相比还有两个特性:⑴着火时无滴落物现象;⑵在着火时外表构成密实的碳层,这就阻止了进一步熄灭。建筑科学技术中心曾对发泡水泥板进行检验,证明它抗火焰性好,如从焊枪喷出的高达3000℃温度的火焰对准泡沫板,2分钟后板反面还未记载到有明显的热感,且无高温热合成和发烟。
2.5 good fire resistance and quenching resistance. Because Portland cement is an inorganic non-combustible material, and there are no organic fibers and additives in the formula, the foam board made of Portland cement does not burn at 1000 C, reaching A1 level of fire prevention, while the organic thermal insulation material can only achieve B1 level (separate fire source from extinguishing). The extinguishing performance of foamed cement insulation board has two aspects: 1) the ability to avoid flame diffusion, that is to say, it can block partial flame diffusion and extinguish itself; 2) the material itself has good thermal insulation, even if extinguished on one side of the material, the temperature on the other side will not rise higher and cause fire expansion. Compared with polystyrene foam and polyurethane foam, there are two characteristics: 1. There is no drop phenomenon during ignition; 2. When the fire occurs, the outer surface forms a dense carbon layer, which prevents further quenching. The building science and technology center has tested the foamed cement board, proving that it has good flame resistance. For example, the flame emitted from the welding gun reaches the temperature of 3000 degrees Celsius for the foam board. After 2 minutes, the reverse side of the plate has not been recorded with obvious heat sensation, and no high temperature thermal synthesis and smoke.
2.6 施工性能优越。由于硅酸盐发泡水泥板外表都是2mm左右的小孔,用砂浆粘贴十分便当,经过小孔比外表积的增加大大进步了板与墙面的结实度。
2.6 superior construction performance. Because the exterior of the silicate foamed cement board is about 2 mm small holes, it is very convenient to paste with mortar. The compactness of the board and the wall is greatly improved by the increase of the specific surface area of the small holes.
2.7 防水性能良好。发泡板本身是闭孔构造,水分无法自在流窜,加上施工中抹满砂浆,一旦墙面部分渗水也不像有机发泡板墙面发作四处活动的现象,便于渗水维修。
2.7 waterproof performance is good. Foam board itself is a closed-cell structure, water can not flow freely, coupled with the construction of plastering mortar, once the wall part of the seepage is not like the phenomenon of organic foam board wall activity around, easy to seepage maintenance.
2.8 化学稳定性强。发泡水泥保温板在抗化学性、溶剂性方面优于其他有机材料,契合《外墙外保温技术规程》JGJ144-2004的规则。而且在施工中能与任何水溶性胶类、溶剂型胶类并用,应用范围广。
2.8 strong chemical stability. Foamed cement insulation board is superior to other organic materials in chemical resistance and solvent resistance, which conforms to the rules of JGJ144-2004. Moreover, it can be used in any construction with any water-soluble glue or solvent based adhesive.
2.9 耐久性。《外墙外保温技术规程》JGJ144-2004还规则了外墙外保温工程各项组成局部应具有物理稳定性,在可能遭到生物损害(鼠害、虫害等)时,外墙保温工程还应具有防生物损害性能;在正确运用和正常维护下,外墙外保温工程的运用年限不少于25年。硅酸盐水泥发泡保温板在一定的温度范围内具有良好的热稳定性,其在呈现收缩或开裂之前的连续运用温度范围为140~175℃,并有禁受不连续运用的辐照温度高达180℃的报道。发泡水泥板发泡组分中掺入惰性填料可明显进步热稳定性,如参加10%的玻璃纤维的发泡水泥泡沫可禁受800℃高温1小时不呈现收缩或开裂。发泡水泥板在低温下运用不受限制。这些性能是其他有机材料所不能及的(有机材料老化寿命普通是15~20年)。
2.9 durability. JGJ144-2004 also stipulates that the components of exterior wall exterior thermal insulation project should be physically stable. When biological damage (rodents, pests, etc.) may occur, the exterior wall thermal insulation project should also have the ability to prevent biological damage. Under correct operation and normal maintenance, the service life of exterior wall thermal insulation project should be limited. Not less than 25 years. Portland cement foamed insulation board has good thermal stability in a certain temperature range. The temperature range of continuous application before shrinkage or cracking is 140-175 C. It has been reported that the irradiation temperature of discontinuous application is up to 180 C. The addition of inert fillers in foamed cement board can obviously improve thermal stability. For example, the foaming cement foam of 10% glass fiber can withstand 800 degree high temperature for 1 hours without shrinkage or cracking. The use of foamed cement boards is not limited at low temperatures. These properties can not be achieved by other organic materials (organic material aging life is usually 15~20 years).
