防水基层作业条件

Working conditions for waterproof base layer

1、彩钢瓦基面无尘土、无松动。松动部分处理后才能施工。

1. The base surface of the colored steel tile is free of dust, soil, and looseness. Construction can only be carried out after the loose parts are treated.

2、基面不得有积水现象，如有必须进行加固处理，合格后方可进行防水层施工。

2. There should be no water accumulation on the base surface. If there is any, reinforcement treatment must be carried out, and the waterproof layer construction can only be carried out after it is qualified.

3、彩钢瓦缝隙超过03MM时要进行加固处理,处理后方可进行施工。

3. When the gap between the colored steel tiles exceeds 03MM, reinforcement treatment should be carried out before construction can proceed.

4、阴阳角、桩立面与平面阴角、立面内角和外角必须做附加层。

4. Internal and external corners, pile facade and plane internal corners, Internal and external angles of facade must be added.

5、早上施工,彩钢瓦面有露水时,要停止施工。

5. Construction should be stopped in the morning when there is dew on the colored steel tile surface.

6、严冬施工彩钢瓦上要刷基层处理剂。

6. In severe winter construction, the colored steel tiles should be coated with base treatment agent.

下面济南彩钢瓦厂再来讲讲其操作工艺：

Next, let's talk about the operation process of Jinan Color Steel Tile Factory:

1.清理基面：用托布把旧彩钢瓦面上的尘土擦去，如有铁锈要铁锈，达到平整干净。

1. Clean the base surface: Use a cloth to wipe off the dust on the old colored steel tile surface. If there is rust, remove it to achieve a flat and clean surface.

2.做附加层：阴阳角、通风口、天沟等处要做附加层，附加层为15cm-30cm宽，沿阴阳角的中轴线延长铺贴。

2. Make additional layers: Additional layers should be made at internal and external corners, vents, gutters, etc. The additional layer should be 15cm-30cm wide and extended along the central axis of the internal and external corners.

3.大面积施工：

3. Large area construction:

a.先弹基准线，这样铺贴出的卷材整齐美观。

a. Snap the baseline first, so that the laid roll is neat and beautiful.

b.平铺卷材，对齐放正卷材与要施工的部位，可从两边卷起卷材。

b. Lay the roll material flat, align it with the area to be constructed, and roll the roll material from both sides.

c.从中割开隔离纸，一边揭去隔离纸,一边挤压卷材，尽量使卷材平整。

c. Cut the isolation paper from it, remove it while squeezing the coil to make it as flat as possible.

4.要求：

4. Requirements:

a.铺贴卷材时，施工时从流水下坡方向开始铺。立墙面从高处向下方铺。

a. When laying coiled materials, start from the downhill direction of flowing water during construction. Lay the vertical wall from a height downwards.

b.排除空气，随卷材滚动压排挤卷材内空气,让卷材牢固粘结。

b. Purge the air and press and squeeze the air inside the coil as it rolls, ensuring a firm bonding of the coil.

c.在温度较低时，基层和卷材必须同时涂刷基层处理剂。

c. When the temperature is low, both the base layer and the coil must be coated with the base layer treatment agent at the same time.

d.卷材搭接长边为3cm-8cm，短边为10cm。

d. The lap length of the coil is 3cm-8cm, and the short edge is 10cm.

e.外露卷材短边搭接、卷材收头及异性部位等，应采用密封膏密封。卷材立墙收头原则上用金属压条固定在预留凹槽内，再用密封膏密封。

e. Sealing paste should be used to seal the short edge overlap, end closure, and opposite parts of exposed coils. In principle, the end of the coiled material wall should be fixed in the reserved groove with metal pressure strips, and then sealed with sealing paste.

注意，刚施工完毕的防水层,不要随便揭开,因为这种材料是粘结的时间越久粘结的越牢固.如果揭开二次一上,就会出现粘结不牢固现象。更多相关事项就来我们网站http://sxhtyz.com咨询！

Note that the waterproof layer that has just been constructed should not be removed casually, as the longer the material is bonded, the stronger it will become. If it is removed twice, it will result in weak bonding. For more related matters, come to our website http://sxhtyz.com consulting service
