一、噴糙土工膜機(jī)組概述

糙面土工膜表面由凹凸?fàn)罱Y(jié)構(gòu)組成，摩擦系數(shù)高，具有防滑性，與光面土工膜 相比，糙面土工膜不僅能應(yīng)用于樓房屋頂防漏，園林綠化，農(nóng)田水渠防滲和水土保持，灘涂圍墾造田、環(huán)境工程中的垃圾填埋、三廢處理和環(huán)境整治、防止沙漠化等工程，還能應(yīng)用于陡坡或邊坡膜體表面需要覆土等要求有較大摩擦系數(shù)的工程項(xiàng)目中，是山區(qū)施工、陡坡施工等工程項(xiàng)目的理想材料。

目前糙面土工膜的生產(chǎn)通常有噴絲加糙法、充氮加糙法，軋花輥壓延法。其中噴絲加糙法屬于二次成型，是通過特殊的噴塑設(shè)備噴絲，將熔融狀的塑料絲涂在所需加糙的土工膜表面，經(jīng)過冷卻從而制得糙面土工膜的一種方法。該生產(chǎn)方式的優(yōu)點(diǎn)如下：

1、與充氮加糙法相比，不會在土工膜表面或內(nèi)部形成氣泡或孔洞等從而降低土工膜的各項(xiàng)質(zhì)量指標(biāo)。

2、與軋花輥壓延法相比，設(shè)備投資相對小，加工周期短，而且壓延法生產(chǎn)的糙面土工膜表面均一，平整，表面摩擦力相對小，如需不同規(guī)格糙面需不斷更換花輥。

3、由于噴絲加糙法是在土工膜生產(chǎn)后二次加糙，所以對土工膜生產(chǎn)時(shí)原料要求寬松。而且對于不論有吹膜設(shè)備還是有壓延設(shè)備的廠家，都不需要設(shè)備改造即可生產(chǎn)糙面土工膜。

4、噴絲加糙法適合生產(chǎn)不同厚度的糙面土工膜。

二、噴絲加糙法土工膜設(shè)備的組成及優(yōu)勢

1、主動(dòng)型放卷裝置，速度可調(diào)，適合不同厚度土工膜的放卷。

2、設(shè)計(jì)獨(dú)特的履帶牽引裝置，能保證不同厚度土工膜的平整、平穩(wěn)牽引

3、穩(wěn)固的噴絲操作平臺機(jī)架

4、設(shè)計(jì)巧妙的噴絲機(jī)構(gòu)，滿足不同寬度土工膜的加糙，并可以土工膜兩邊留有余量

5、操作方便的式收卷裝置

6、全生產(chǎn)線智能化通訊控制，自動(dòng)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.
