    抹面砂浆Plaster mortar

    一、产品用途

    聚合物抹面砂浆适用于外墙保温系统的防护层,与耐碱玻纤网格布(热镀锌钢丝网)复合粘覆在保温浆料上,形成增强保温体系耐久性的保护层,提高体系的机械强度和抗裂性能。

    二、产品特点

    1.无毒无害无味,安全环保

    2.粘结强度高、柔性好、抗渗、防水、抗裂等特点

    3.施工方便施工时无需振捣,在现场加水搅拌即可使用。

    4.具有优良的耐候、抗冲击和防裂性能。

    、执行标准:JG 158-2004 《胶粉聚苯颗粒外墙外保温系统》

    、施工方法

     聚合物抹面砂浆的配制是与水按41左右的比例,并在干净的搅拌桶内先放适量清水缓缓倒干粉砂浆,浸润后用机械搅拌器搅拌均匀。拌好的料在静置10min后再次搅拌成粘稠料浆即可,并按使用规范要求抹面。一般墙体抹灰23mm,外墙体保温抹底层砂浆2-3mm,贴压网格布后抹面层砂浆12mm,抹面砂浆与基层必须粘结牢固无脱层、空鼓。

     2、拌好的物料应在2小时内用完,忌再次搅拌或加入它材料搅拌。

     3、未开封保存阴凉干燥处,保质期6个月


    Product use

    Mortar for protective layer on the external wall insulation system, and alkali fiberglass mesh cloth (galvanized steel wire) composite adhered to the insulating slurry, forming a protective layer that enhances durability of thermal insulation system, improve the system of the mechanical strength and the anti cracking performance.

     

    Product features

    1. innocuous innocuous and tasteless, safe and environmental protection.

    2. characteristics of high bond strength, good flexibility, seepage resistance, waterproof, crack resistance and so on

    3. the construction is convenient, without vibration in the construction, and can be used in the field with water mixing.

    4. has excellent weatherability, impact resistance and crack resistance.

     

    Construction method

    Preparation of polymer mortar and water according to the ratio of about 4:1, and the stirring barrel clean in the amount of water release slowly poured into the dry mortar, soaked with the agitator stirring. The mixture in static 10min again after mixing into a viscous slurry, and by the use of standard precausions. General wall plastering 2 - 3mm, the exterior wall insulation mortar with bottom 2-3mm, pressing the mesh after plastering mortar mortar and 1 - 2mm, the grassroots level must be firmly bonded without delamination and hollowing.

     

    Matters needing attention

    1. the construction temperature of 5 DEG C - 35 DEG C, the wind is not more than 5, in the construction process should avoid the rain;

    2. The mixed material should be used in 2 hours, and should not be stirred again or add water and other materials.

    3. Unsealed and dry place is not opened, and the shelf life is 6 months
