5、西卡滲耐PVC防水系統(tǒng)在舊屋面改造中的優(yōu)勢
Advantages of Sika Sarnafil PVC Waterproof system
1）、整體防水效果好，熱風焊接實現(xiàn)屋面無縫處理。
Good overall waterproof effect, seamless roof processed by hot-air welding.
采用柔性PVC防水材料，其熱風焊接的施工工藝，使得整個屋面處于無縫狀態(tài),沒有了滲漏的隱患。把所有的結構部件覆蓋在防水層下面，使整個屋面系統(tǒng)免受外界腐蝕，并且可以隨基層作任意變形。
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）、優(yōu)越的防火性能，滲耐PVC防水卷材的防火性能為B2級（離火自熄）。
Superior fireproof performance, the safety performance of Sarnafil PVC waterproofing membrane achieves the B2 level (from the fire extinguish).
3）、超過35年的使用壽命。通過英國權威認證機構BBA對滲耐柔性輕鋼屋面系統(tǒng)具有超過35年的使用壽命認證。
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）、系統(tǒng)自身荷載輕，不會對原有基層增加額外的荷載。
Light Weight of the system will not increase the additional load on the original basic layer.
5）、屋面防水施工不影響建筑內部的使用功能、更環(huán)保；
Roof waterproofing installation will not affect the use of functions inside the building and be more useful for environmental protection.
幾乎無噪音、振動、無刺鼻氣味，現(xiàn)場應用熱風焊接，非明火，產生的污染少。
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）、不破壞原有結構
Do not destroy the original structure
使用固定件固定卷材于維護結構上或屋面表面。
PVC membranes will be fastened by the fastener on the maintenance structure or the roof surface.
7）、施工便捷，優(yōu)越的細部處理
Convenient installation, excellent detail treatment.
節(jié)點易于處理與PVC材料本身的柔韌性和熱風焊接功能有主要關系。尤其對天溝、女兒墻等部位的處理，可以有效保證施工質量，從根本上避免了傳統(tǒng)屋面的風險。
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）、特有的塑料本質，能很好的解決雨噪聲，從而給工廠帶來安靜的作業(yè)環(huán)境。
Unique plastic nature will be a good solution to the rain noise and bring the quiet operating environment to the factory.

Sikaplan F型卷材是一種勻質防水卷材，適用于各種施工方法。勻質卷材是由雙層薄膜熱熔而成。
Sarnafil® F is homogenous waterproofing membrane suitable for different applications.It is produced as a single layer membrane with additional top layer.
所有運到施工現(xiàn)場的產品應密封貯存或包裝，搬運時防止對產品的損壞，卷材應用帆布保護防潮，并存放在地勢高的地方，如托盤、木材上。一旦卷材在貯存時受潮浸水，卷材焊接質量就會受到影響。
所有易燃材料應存放在涼爽干燥處，遠離火星和明火。
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應事先計劃好，以適應工地和天氣條件。
- 確定好每天的工作步驟。
- 確保工作面上能及時排水
- 確保每天的工作面都全部密封（當日工作面，焊縫和周邊，壓條上的焊接等部位的防水…）
- 安排好工序，避免在新鋪好的屋面上行走，拖拉設備或存放物品。必要時，施工方應保護卷材免受損壞。
- 在施工前和施工中，應清除表面上的所有灰塵、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.
焊接卷材時，搭接部分必須清潔干燥。對于滿粘系流，PVC卷材的搭接寬度應為80mm。
When welding membrane, the overlap area must be clean and dry.
The overlap is 80mm for fully adhered applications.
只能采用西卡滲耐認可的焊接工具。
下列工具用于焊接西卡滲耐卷材：
1 手持式焊槍
2 20mm寬焊嘴
3 40mm寬焊嘴
4 壓輥
5 焊繩焊嘴

粘結概況General Information - Adhering
? 808/606/ 膠粘劑 Sarnacol / 808/606/ adhesive
- 卷材只能粘附在耐熔劑、干燥且沒有灰塵的表面上，表面不能過度粗糙，被污染，或有其他類似問題。
- 鋪開西卡滲耐卷材，調整對齊，并向后折回大約一半的卷材寬度。
- 用膠輥和刮板分別在屋面基層和卷材底面上均勻地涂上一層滲耐808膠粘劑。
- 根據(jù)環(huán)境溫度，分段地涂膠粘劑，并使膠粘劑中的溶劑充分揮發(fā)(手觸檢查)。揮發(fā)時間在很大程度上取決于天氣條件、承載層和膠粘劑的用量。
- 待溶劑揮發(fā)后將卷材鋪在涂膠的承載層上，并使用手持式壓輥壓實。
- 折回另一半卷材，并重復上述程序。
