濟(jì)南推拉蓬:PE篷布使用的性能介紹

來源:http:/// 日期:2023-12-22 發(fā)布人:

1、透氣性

1. Breathability

遮陽篷的透氣性是必須考慮的,尤其是軍用遮陽篷。結(jié)構(gòu)、密度、材料、防水涂料種類和樹脂附著力是影響透氣性的因素。隨著樹脂附著力的增加,遮陽篷的透氣性降低。當(dāng)然,這和整理劑有關(guān)。

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、抗拉強(qiáng)度

2. Tensile strength

篷布在使用中應(yīng)能承受各種拉力,如固定時(shí)的拉力、使用過程中的風(fēng)、雨、結(jié)等附加力。雖然有這些外力作用,但還是需要保持原有的形狀,不易變形,這就要求篷布的拉伸強(qiáng)度很高,垂直和水平拉伸強(qiáng)度不宜相差太大。特別是對(duì)于用于充氣施工的大型方艙來說,拉伸強(qiáng)度尤為重要?;纪ǔS筛邚?qiáng)度聚酯、聚酯等長纖維織物制成。表面用氯乙烯樹脂和氯磺化聚乙烯樹脂處理。產(chǎn)品的強(qiáng)度主要取決于纖維材料的強(qiáng)度和織物的密度。

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、彈性表皮和尺寸穩(wěn)定性

3. Elastic skin and dimensional stability

它們常用于緊張的環(huán)境中,作為雨棚和溫室。織物的伸長率不宜過大,其尺寸穩(wěn)定性取決于材料的蠕變性能。

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

防水是防水布的一個(gè)重要特點(diǎn)。氯乙烯樹脂通過浸漬填充到織物結(jié)構(gòu)的縫隙中,形成薄膜。如果單位面積的樹脂附著力超過一定程度,耐水性不成問題。如果薄膜較薄,在彎曲、摩擦或磨損時(shí)容易斷裂,可能會(huì)產(chǎn)生渾水。

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.
