1．需保溫的設施和管道應無泄漏，表面干燥，無油脂，無銹蝕在這些條件下，為利于防腐，可采取適當涂層。

1. Facilities and pipelines that require insulation should have no leaks, dry surfaces, no grease, and no rust. Under these conditions, appropriate coatings can be applied to facilitate corrosion prevention.

2．為達到熱損失zui小目的，板和氈的所有接頭一定要對接十分緊密，在多層保溫時各個十字接縫應交錯開來，以免形成熱橋，在保冷時必需杜絕冷橋。

To achieve the goal of minimizing heat loss, all joints between the board and felt must be tightly connected. When insulation is applied in multiple layers, the cross joints should be staggered to prevent the formation of thermal bridges. Cold bridges must be avoided during insulation.

3．巖棉制品用于室外保溫或者在易受機械磨損的地方宜用金屬或塑料皮，并注意接頭，接縫的密封，必要時加膠質封條，包裹層重疊部分不小于100mm 。

3. Rock wool products should be used for outdoor insulation or in areas prone to mechanical wear and tear. Metal or plastic skin should be used, and attention should be paid to the sealing of joints and seams. If necessary, adhesive seals should be added, and the overlapping part of the wrapping layer should not be less than 100mm.

4．用于保冷一定要在保冷面加防潮層，在溫度特別低的情況下，用不含樹脂的巖棉進行絕熱，其防潮層也必須是防火的。

4. When used for cold insulation, a moisture-proof layer must be added to the cold insulation surface. In particularly low temperatures, non resin rock wool should be used for insulation, and the moisture-proof layer must also be fire-resistant.

5．當溫度超過200℃ 時，保溫必須加合適的外護，這樣可能產生的膨脹就不會使厚度和容重發生變化。

When the temperature exceeds 200 ℃, appropriate external protection must be added to the insulation, so that the possible expansion will not cause changes in thickness and bulk density.

6．對于大直徑或平壁設備用巖棉制品保溫，超過200℃ 時應加保溫釘，（間距400mm ）外護要貼緊。

For large-diameter or flat wall equipment, rock wool products should be used for insulation. When the temperature exceeds 200 ℃, insulation nails should be added, and the outer protection should be tightly attached (with a spacing of 400mm).

7．當保溫對象垂直放置，具有相當高度時，其保溫層一定要有定位銷或支承環，間距不要大于3 米，以防保溫材料在有震動時向下滑動。

7. When the insulation object is placed vertically and has a considerable height, its insulation layer must have positioning pins or support rings, with a spacing of no more than 3 meters, to prevent the insulation material from sliding down in the presence of vibration.

8．室外保溫，保冷施工不宜在雨天進行，否則應采取防雨措施。

8. Outdoor insulation and cold insulation construction should not be carried out on rainy days, otherwise rainproof measures should be taken.

外墻用巖棉(外墻薄抹灰用巖棉施工介紹)

外墻用巖棉主要一點是要求具有強度和一定的抗拉力。

The main requirement for using rock wool for exterior walls is to have strength and certain tensile resistance.
