无机保温砂浆的选择我给你几点建议

时间:2016-01-06     作者:华东公司【原创】   阅读

目前无机保温砂浆主要是玻化微珠保温砂浆和膨胀珍珠岩保温砂浆,二者区别在于:膨胀珍珠岩的材性颗粒大、开口的,吸水率高,导热系数大于玻化微珠,并且吸水后导热系数是不可逆的。玻化微珠颗粒小,闭口的,基本不吸水。

Inorganic insulation mortar at present is mainly vitrified beads insulation mortar and expanded perlite insulation mortar, the difference is: the expanded perlite particles on the big, open, bibulous rate is high, the coefficient of thermal conductivity is greater than the vitrified beads, and after water absorption coefficient of thermal conductivity is not reversible. Vitrified microsphere particles small, silent, basic not bibulous.

无机保温砂浆的选择:

The choice of inorganic insulation mortar:

1、如选用膨胀珍珠岩作为外墙保温砂浆中作主要绝热材料应该密切注意膨胀珍珠岩的吸水率。由于膨胀珍珠岩产品是开口型颗粒,因此它的吸水率达到200%-300%容易造成砂浆上墙以后开裂脱落空鼓,以及渗水,膨胀珍珠岩的导热系数在吸水后不可逆的,这就破坏了它的隔热保温功能。那么膨胀珍珠岩作为绝热材料,必须是憎水型的,也就是通过烧制出来以后增加一个憎水剂喷涂的工艺。

1, if choose expanded perlite as the main insulation of exterior wall thermal insulation mortar should pay close attention to the expanded perlite bibulous rate. Since expanded perlite products is open rack particles, so its water absorption rate of 200% - 300% likely to cause cracking mortar on the wall after fall off empty drum, and water seepage, the coefficient of thermal conductivity of expanded perlite irreversible after absorbing water, it undermines its insulation heat preservation function. Then expanded perlite as insulation materials, must be hydrophobic type, namely by fire after adding a hate water spraying process.

2、如采用珠化微珠作为绝热材料的,除了水泥、胶粉短切纤维,增稠剂,粉煤灰和石膏外,应该在组份中添加一定比例的粗颗粒。

2, if use pearl beads as heat insulation material, in addition to cement, powder, short cut fiber, thickening agent, fly ash and gypsum, a percentage of coarse particle should be added in the components.

3、在无机保温材料中使用石膏作为组分的,石膏的添加比例要严格控制,它遇水后线性伸缩比例很高,容易造成开裂等问题,因此也要要添加憎水剂。

3, use gypsum as a component in the inorganic heat preservation material, gypsum shall strictly control the adding proportion of it in the water after linear expansion ratio is high, easy to cause the problem such as craze, so also want to add a hate water.

4、干密度越大导热系数越大,反之越小。要保温材料的强度(抗压强度,拉伸粘合强度)和抗风压必须要有足够的胶凝材料以及材料的颗粒级配,全部是细粉料的组合,容易开裂

4, the greater the dry density, the greater the coefficient of thermal conductivity, the smaller the vice. To the strength of the insulation material (compressive strength, tensile bond strength), and resistance to wind pressure must have enough gelling material and grain size distribution, all is the combination of fine powder, easy to crack
