一、喷糙土工膜机组概述

糙面土工膜表面由凹凸状结构组成，摩擦系数高，具有防滑性，与光面土工膜 相比，糙面土工膜不仅能应用于楼房屋顶防漏，园林绿化，农田水渠防渗和水土保持，滩涂围垦造田、环境工程中的垃圾填埋、三废处理和环境整治、防止沙漠化等工程，还能应用于陡坡或边坡膜体表面需要覆土等要求有较大摩擦系数的工程项目中，是山区施工、陡坡施工等工程项目的理想材料。

目前糙面土工膜的生产通常有喷丝加糙法、充氮加糙法，轧花辊压延法。其中喷丝加糙法属于二次成型，是通过特殊的喷塑设备喷丝，将熔融状的塑料丝涂在所需加糙的土工膜表面，经过冷却从而制得糙面土工膜的一种方法。该生产方式的优点如下：

1、与充氮加糙法相比，不会在土工膜表面或内部形成气泡或孔洞等从而降低土工膜的各项质量指标。

2、与轧花辊压延法相比，设备投资相对小，加工周期短，而且压延法生产的糙面土工膜表面均一，平整，表面摩擦力相对小，如需不同规格糙面需不断更换花辊。

3、由于喷丝加糙法是在土工膜生产后二次加糙，所以对土工膜生产时原料要求宽松。而且对于不论有吹膜设备还是有压延设备的厂家，都不需要设备改造即可生产糙面土工膜。

4、喷丝加糙法适合生产不同厚度的糙面土工膜。

二、喷丝加糙法土工膜设备的组成及优势

6、全生产线智能化通讯控制，自动化程度高

Spray type Textured Geomembrane production Line

Introduction:

The surface of the textured geomembrane consists of a concave-convex structure with high friction coefficient and anti-slip property. Compared with the smooth geomembrane, the textured geomembrane can be applied not only to the roof of the building for leak prevention, landscaping, farmland canal seepage prevention and soil and water conservation. Landfill reclamation, landfill in environmental engineering, three-waste treatment and environmental remediation, prevention of desertification, etc., can also be applied to steep slopes or slopes where the surface of the membrane needs to be covered, and other projects requiring a large friction coefficient. The preferred material for construction projects such as mountain construction and steep slope construction.

At present, the production of textured geomembrane usually has the method of Spray and roughening, nitrogen filling and roughening, and embossing roll calendering. Among them, the Spray and roughening method is a secondary molding, which is a method of spraying a molten plastic wire onto the surface of geomembrane to be roughened by a special spray equipment, and cooling to obtain a textured geomembrane.

First, the advantages of this production method are as follows:

1. Compared with the method of nitrogen filling and roughening, no bubbles or holes are formed on the surface or inside of the geomembrane to reduce the quality indexes of the geomembrane.

2. Compared with the calender roll calendering method, the equipment investment is relatively small, the processing cycle is short, and the surface of the rough geomembrane produced by the calendering method is uniform, flat, and the surface friction is relatively small. If different specifications of rough surface are required, the flower roll needs to be replaced continuously. .

3. Since the Spray roughening method is secondary roughening after the production of the geomembrane, the raw material requirements for geomembrane production are loose.

Moreover, for manufacturers who have blown film equipment or calendering equipment, no need equipment modification to produce rough surface geomembrane.

4, Spray and roughening method is suitable for the production of rough surface geomembrane with different thickness.

Second, the composition and advantages of the geomembrane Spray equipment

1. Active roll loading device with adjustable speed, suitable for roll loading of geomembrane with different thicknesses.

2. The unique design of the crawler traction device can ensure the uniform and smooth traction of geomembranes with different thicknesses.

3. Stable spray operation platform tower.

4. The design of the ingenious spray mechanism meet the different width of the geomembrane roughening and can leave a margin on both sides of the geomembrane.

5. Convenient central winding device

6. The entire production line intelligent communication control, high degree of automation.
