济南推拉蓬:PE篷布使用的性能介绍

来源://www.shmtd.com/ 日期:2023-12-22 发布人:

1、透气性

1. Breathability

遮阳篷的透气性是必须考虑的,尤其是军用遮阳篷。结构、密度、材料、防水涂料种类和树脂附着力是影响透气性的因素。随着树脂附着力的增加,遮阳篷的透气性降低。当然,这和整理剂有关。

The breathability of sunshades must be considered, especially for military sunshades. Structure, density, material, type of waterproof coating, and resin adhesion are factors that affect air permeability. As the resin adhesion increases, the breathability of the sunshade decreases. Of course, this is related to the finishing agent.

2、抗拉强度

2. Tensile strength

篷布在使用中应能承受各种拉力,如固定时的拉力、使用过程中的风、雨、结等附加力。虽然有这些外力作用,但还是需要保持原有的形状,不易变形,这就要求篷布的拉伸强度很高,垂直和水平拉伸强度不宜相差太大。特别是对于用于充气施工的大型方舱来说,拉伸强度尤为重要。基布通常由高强度聚酯、聚酯等长纤维织物制成。表面用氯乙烯树脂和氯磺化聚乙烯树脂处理。产品的强度主要取决于纤维材料的强度和织物的密度。

The tarpaulin should be able to withstand various tensile forces during use, such as the tension during fixation, and additional forces such as wind, rain, and knots during use. Although there are external forces, it is still necessary to maintain the original shape and not easily deform, which requires the tensile strength of the tarpaulin to be high, and the vertical and horizontal tensile strength should not differ too much. Especially for large shelters used for inflatable construction, tensile strength is particularly important. The base fabric is usually made of high-strength polyester, polyester and other long fiber fabrics. The surface is treated with vinyl chloride resin and chlorosulfonated polyethylene resin. The strength of a product mainly depends on the strength of the fiber material and the density of the fabric.

3、弹性表皮和尺寸稳定性

3. Elastic skin and dimensional stability

它们常用于紧张的环境中,作为雨棚和温室。织物的伸长率不宜过大,其尺寸稳定性取决于材料的蠕变性能。

They are commonly used in tense environments as canopies and greenhouses. The elongation of the fabric should not be too large, and its dimensional stability depends on the creep performance of the material.

4、耐水性

4. Water resistance

防水是防水布的一个重要特点。氯乙烯树脂通过浸渍填充到织物结构的缝隙中,形成薄膜。如果单位面积的树脂附着力超过一定程度,耐水性不成问题。如果薄膜较薄,在弯曲、摩擦或磨损时容易断裂,可能会产生浑水。

Waterproofing is an important feature of waterproof cloth. Vinyl chloride resin is impregnated and filled into the gaps of the fabric structure to form a thin film. If the resin adhesion per unit area exceeds a certain level, water resistance is not a problem. If the film is thin, it is prone to breakage during bending, friction, or wear, and may produce muddy water.
