章丘鸿祥泰小编就带你了解岩棉板的标准及注意事项有哪些?

Zhangqiu hongxiangtai small weaving will take you to understand the standards and precautions of rock wool board?

外墙保温岩棉板外墙保温岩棉板为外墙保温专用岩棉板,A级不燃性防火保温材料,较高的抗压和抗拉伸强度、较低的吸水和吸湿性、尺寸稳定性良好、不会产生热膨胀或收缩、耐老化等优点。

Rock wool board for external wall thermal insulation is a special rock wool board for external wall thermal insulation. It is a class a non combustible fireproof insulation material. It has the advantages of high compressive strength, tensile strength, low water absorption and moisture absorption, good dimensional stability, no thermal expansion or contraction, aging resistance, etc.

外观质量:板面平整,无明显凹凸、翘曲、变形;表面清洁,色泽均匀,无胶痕、油污;无明显划痕、磕碰、伤痕等;切口平直,切面整齐,无毛刺;面材与芯材之间粘结牢固,芯材密实。

Appearance quality: the board surface is flat, without obvious concave convex, warpage and deformation; the surface is clean and uniform in color, without glue mark and oil stain; there is no obvious scratch, bump, scar, etc.; the incision is straight, the section is neat, and there is no burr; the bonding between surface material and core material is firm, and the core material is dense.

注意事项

matters needing attention

1.要注意防雨,不能在雨天施工。

1. Pay attention to rainproof, and do not construct in rainy days.

2.用于保冷必然要在加防潮层,在温度特殊低的状况下,用不含树脂的岩棉进行绝热,其防潮层也必需是防火的

2. When it is used for cold insulation, moisture-proof layer must be added. Under special low temperature condition, rock wool without resin is used for heat insulation, and its moisture-proof layer must also be fireproof

3.当温度超过一定的温度,比如:200℃ 时,保温必需加适宜的外护,这样就不会使岩棉板厚度和容重发生转变。

3. When the temperature exceeds a certain temperature, such as 200 ℃, appropriate external protection must be added to the insulation, so that the thickness and bulk density of rock wool board will not change.

4.有关大直径和平壁设备用岩棉成品保温,超越200℃ 时,一定要谨记岩棉板生产厂家的叮嘱:加保温钉,(间距400mm左右 )外护要贴紧。

4. For insulation of rock wool products for large diameter and flat wall equipment, when the temperature exceeds 200 ℃, it is necessary to bear in mind the instructions of the rock wool board manufacturer: add thermal insulation nails (with a spacing of about 400mm), and the outer protection should be tightly attached.

5.需保温的设备、保温钉以及管道为利于防腐,可接纳恰当涂层。另外应没有任何走漏的地方。这样可以达到更好的效果。

5. Equipment, nails and pipes to be insulated can be coated properly for corrosion protection. In addition, there should be no leakage. This can achieve better results.

6.岩棉板成品在室外保温的情况下易受机械磨损的应宜用金属或塑料包皮,然后留意接头的地方,接缝的密 封,需要时加胶质封条,包裹层堆叠局部不小于100mm

6. If the finished rock wool board is easy to be mechanically abraded under outdoor thermal insulation, metal or plastic wrapping should be used. Then, pay attention to the joint position and joint sealing. If necessary, glue seal should be added. The stacking part of the wrapping layer should not be less than 100 mm

7.当保温对象呈90度放置,且有一定的高度时,岩棉板的保温层必然要有定位销或支承环,间距一定不要大于3米,以防保温资料在有震动时向下滑动。

7. When the insulation object is placed at 90 degrees and has a certain height, the insulation layer of rock wool board must have positioning pin or supporting ring, and the spacing must not be greater than 3 meters, so as to prevent the insulation material from sliding downward in case of vibration.

8.为了可以达到热损掉最小目标,岩棉板和毡的接头一定要对接严密,如果有多层保温时各个十字接缝需要交织开来,以免构成热桥,在保冷时必须根绝冷桥。

8. In order to achieve the goal of minimizing heat loss, the joints of rock wool board and felt must be tightly butted. If there are multi-layer insulation, each cross joint needs to be interlaced to avoid forming a thermal bridge. In cold insulation, the cold bridge must be isolated.
