        5、西卡渗耐PVC防水系统在旧屋面改造中的优势

  Advantages of  Sika Sarnafil PVC Waterproof system

1)、整体防水效果好,热风焊接实现屋面无缝处理。

Good overall waterproof effect, seamless roof processed by hot-air welding.

采用柔性PVC防水材料,其热风焊接的施工工艺,使得整个屋面处于无缝状态,没有了渗漏的隐患。把所有的结构部件覆盖在防水层下面,使整个屋面系统免受外界腐蚀,并且可以随基层作任意变形。

The flexible PVC waterproofing material installed by the construction process of hot-air welding makes the entire roof in a seamless state, without the risks of leakage. All the structural components are covered below the waterproof layer, so that the roofing system can avoid the outside corrosion, and shape with the basic layer.

2)、优越的防火性能,渗耐PVC防水卷材的防火性能为B2级(离火自熄)。

Superior fireproof performance, the safety performance of Sarnafil PVC waterproofing membrane achieves the B2 level (from the fire extinguish).

3)、超过35年的使用寿命。通过英国权威认证机构BBA对渗耐柔性轻钢屋面系统具有超过35年的使用寿命认证。

In the assessment of Sarnafil the BBA States that the Sarnafil flexible Light Weight Steel Roof Covering System should have a life in excess of 35 years.

4)、系统自身荷载轻,不会对原有基层增加额外的荷载。

Light Weight of the system will not increase the additional load on the original basic layer.

5)、屋面防水施工不影响建筑内部的使用功能、更环保;

Roof waterproofing installation will not affect the use of functions inside the building and be more useful for environmental protection.

几乎无噪音振动无刺鼻气味,现场应用热风焊接,非明火,产生的污染少。

Almost no noise, vibration and no pungent odor, the application of hot-air welding in the site which is non-fire will produce less pollution.

6)、不破坏原有结构

Do not destroy the original structure

使用固定件固定卷材于维护结构上或屋面表面。

PVC membranes will be fastened by the fastener on the maintenance structure or the roof surface.

7)、施工便捷,优越的细部处理

Convenient installation, excellent detail treatment.

节点易于处理与PVC材料本身的柔韧性和热风焊接功能有主要关系。尤其对天沟、女儿墙等部位的处理,可以有效保证施工质量,从根本上避免了传统屋面的风险。

Easy details treatment is mainly related to the flexible property and hot-air welding function of PVC membranes, especially for the gutter, parapet and other details, so as to effectively guarantee the quality of installation and avoid the risk of the traditional roof at all.

8)、特有的塑料本质,能很好的解决雨噪声,从而给工厂带来安静的作业环境。

Unique plastic nature will be a good solution to the rain noise and bring the quiet operating environment to the factory. 


9)、后期使用中的破坏点容易修复
     Easy repair in case of damage



10)、浅色的外表面能有效的反射太阳能,有利于节约能源,减少城市热岛效应
     highly reflective, resulting in energy savings and a reduction in the urban heat island effect



        6、施工说明 Installation General Information

    作为世界防水领域的领导者,西卡渗耐在防水制品技术方面拥有近50年丰富经验。

Sika Sarnafil has about 50 year’s experience in waterproofing plastics technology. Today Sika Sarnafil is a world leader in waterproofing systems.

良好的施工技术能进一步凸显我们产品的优良品质,为此我们非常重视对西卡渗耐产品施工人员的培训。

But even our products are only as good as the workmanship with which they are installed. That is Why we place great emphasis on training people to lay Sika Sarnafil membrane

只有顺利完成我们的培训课程,并且有正规的现场实际操作经验的人员才能进行西卡渗耐系统的施工。

Only those who have successfully completed one of our training courses and have regular, practical site experience may install Sika Sarnafil systems.

    Sikaplan F型卷材是一种匀质防水卷材,适用于各种施工方法。匀质卷材是由双层薄膜热熔而成。

Sarnafil® F is homogenous waterproofing membrane suitable for different applications.It is produced as a single layer membrane with additional top layer.

所有运到施工现场的产品应密封贮存或包装,搬运时防止对产品的损坏,卷材应用帆布保护防潮,并存放在地势高的地方,如托盘、木材上。一旦卷材在贮存时受潮浸水,卷材焊接质量就会受到影响。

所有易燃材料应存放在凉爽干燥处,远离火星和明火。

All membranes delivered to the job site shall be in the original container or wrappings.Handle all materials to prevent damage.

Membrane rolls should be protected against exposure with canvas tarpaulins and must be stored on an elevated level, such as pallets, wood Logs

All flammable materials shall be stored in a cool, dry area away from sparks and open flames.

平型屋面材料的施工程序应事先计划好,以适应工地和天气条件。

确定好每天的工作步骤。

确保工作面上能及时排水

确保每天的工作面都全部密封(当日工作面,焊缝和周边,压条上的焊接等部位的防水…)

安排好工序,避免在新铺好的屋面上行走,拖拉设备或存放物品。必要时,施工方应保护卷材免受损坏。

在施工前和施工中,应清除表面上的所有灰尘、碎屑。

The procedure for installing the flat roofing must be planned beforehand and adapted to the site and weather conditions.

- Define daily work stages.

- Ensure that rain water can drain off at all times.

- Make sure daily work stages are leak proof (waterproofing of daily stages, seams and perimeters welding over fastening bars)

- Arrange word sequences to avoid use of newly constructed roofing as walking surface or for equipment movement and storage. where required, contractor shall provide all necessary protections to prevent membrane from damage.

- Prior and during application, all dirt, debris and dust shall be removed from surface.

焊接卷材时,搭接部分必须清洁干燥。对于满粘系流,PVC卷材的搭接宽度应为80mm

When welding membrane, the overlap area must be clean and dry.

The overlap is 80mm for fully adhered applications.


只能采用西卡渗耐认可的焊接工具。

下列工具用于焊接西卡渗耐卷材:

手持式焊枪

2 20mm宽焊嘴

3 40mm宽焊嘴

压辊

焊绳焊嘴

Only use welding tools approved by Sika Sarnafil.

The following tools are available for welding Sika Sarnafil membranes:

1 Hand welding gun

2 20 mm wide welding nozzle

3 40 mm wide welding nozzle

4 Pressure roller

5 Cord nozzle

粘结概况General Information - Adhering

Ø 808/606/ 胶粘剂      Sarnacol / 808/606/  adhesive


卷材只能粘附在耐熔剂、干燥且没有灰尘的表面上,表面不能过度粗糙,被污染,或有其他类似问题。

铺开西卡渗耐卷材,调整对齐,并向后折回大约一半的卷材宽度。

用胶辊和刮板分别在屋面基层和卷材底面上均匀地涂上一层渗耐808胶粘剂。

根据环境温度,分段地涂胶粘剂,并使胶粘剂中的溶剂充分挥发(手触检查)。挥发时间在很大程度上取决于天气条件、承载层和胶粘剂的用量。

待溶剂挥发后将卷材铺在涂胶的承载层上,并使用手持式压辊压实。

折回另一半卷材,并重复上述程序。
