锌钢道路护栏工艺及特点分析

  锌钢道路护栏工艺及特点分析

  锌钢护栏是指采用锌合金材料制作的锌钢栅栏,由于其具有高强度、高硬度、外观精美、色泽鲜艳等优点,目前已成为住宅小区、场区围墙使用的主流产品。

  传统的护栏使用铁条、铝合金材料,需要借助电焊等工艺技术,而且质地较软、容易生锈、色彩单一。锌钢护栏完美地解决了传统护栏的缺点,而且价格低廉,成为传统阳台护栏材料的替代产品。

  (一)材料

  锌钢护栏由基材和配件组成。

  锌钢护栏型材、锌钢护栏的基材为高温热浸锌材料,热浸锌是指把优质钢材投入几千度的锌液池中,浸泡达一定时间以后锌液就会渗透到钢材中,使之形成一种特 殊的锌钢合金,热浸锌材料表面不经任何处理在野外环境中即可达30年不锈蚀,如:高速公路护栏、高压电塔都是采用高温热浸锌材料,其防锈长达30年之久, 彻底解决了多年来防锈、美观与安全之间的问题。

  锌钢护栏配件采用使用寿命可达50年之久的改性高强度工程尼龙,其强度、硬度远高于普通钢制材料,每平方米可承受183MPA以上的压力,2729MPA的拉伸力,可承受220℃以下高温不变形等优点。

  (二)工艺

  1、锌钢护栏工艺:采用无焊连接、横竖穿插组装而成。相对于传统的武汉铁艺护栏,安装更加快捷,外表更加美观。

  2、锌钢护栏的基材由六层组成,分别是:

  (1)钢材层(Base steel):基材,硬度值为159DPN;

  (2)锌钢合金层(Zeta layer):最靠近基材的一层致密合金层,构造复杂,耐腐蚀性极强,以FeZn7及FeZn13化合存在,硬度值为211DPN,含Fe为7%-11%;

  (3)亚铅层(Delta layer):显著单斜系柱状组织,Fe含量为6%,无毒,耐腐蚀,硬度值为179DPN;

  (4)纯锌层(Eta layer):稠密六方晶系,变形加工不易破裂,锌纯度98.5%,硬度值为70DPN;

  (5)高锌磷化层:具有良好的耐腐蚀性,并增强涂膜与基材附着力;

  (6)阿克苏——诺贝尔彩色离分子高温固化层:优异的防腐性能及抗撞击性能,具有卓越的抗紫外、抗氧化和表面自洁性能,色泽变化率15年不超过5%。

  二、特点

  锌钢护栏具有以下特点:

  1、免焊接的组装式设计,安装快捷简单。

  2、四层防腐处理,二十年以上使用寿命,解决了传统产品短时间内锈蚀、粉化、龟裂等问题,免除了产品维护更新费用。

  3、良好的装饰性,丰富的色彩,满足不同客户对产品的个性化需求。

  4、环保,不污染环境,解决了普通产品污染建筑物问题。

  5、良好的柔韧性能,基材的钢性和柔性使护栏产品具有较好的抗冲击性能。

  6、静电喷涂护栏的仿塘瓷工艺处理的表面,使锌钢护栏产品具有良好的自洁性能,雨水冲刷和水枪喷洗即可光洁如新。

  Process and characteristics analysis of zinc steel road barrier

  Zinc steel guardrail refers to the use of zinc steel fence made of zinc alloy material, because of its high strength, high hardness, beautiful appearance, bright color and other advantages, has become the mainstream residential products, the use of field fence.

  Traditional rail use iron bars, aluminum alloy materials, the need to use welding and other technology, but also more soft texture, easy to rust, a single color. The zinc steel fence perfectly solves the shortcoming of the traditional barrier, and the price is low, and it is the substitute of the traditional balcony fence material.

  (a) material

  The zinc steel fence is composed of base material and parts.

  The substrate of zinc steel guardrail profiles, zinc steel fence for high temperature hot dip galvanized material, hot galvanizing refers to high-quality steel into liquid zinc tank thousands of degrees, soak for some time after the liquid zinc can seep into the steel, so as to form a special kind of zinc alloy steel, hot dip galvanized material surface without any treatment in the wild that is up to 30 years does not rust, such as: highway guardrail, high-voltage tower are used in high temperature hot galvanizing material, its rust for 30 years, completely solve the years between rust, beauty and safety problems.

  Zinc steel guardrail accessories with the service life of up to 50 years of modified high strength nylon engineering, its strength and hardness are higher than those of ordinary steel material, every square metre can withstand the pressure more than 183MPA, tensile strength 2729MPA, advantages can withstand 220 DEG C high temperature deformation etc..

  (two) technology

  1, the zinc steel guardrail process: using solderless connections, they assembled with. Compared with the traditional Wuhan iron fence, installation more convenient, more beautiful appearance.

  2, the base material of the zinc steel fence is composed of six layers, respectively:

  (1) the steel layer (steel Base): the substrate, the hardness value is 159DPN;

  (2) zinc alloy steel layer (Zeta layer): a layer of the most dense layer near the substrate alloy, complex structure, strong corrosion resistance, with FeZn7 and FeZn13 combined, the hardness was 211DPN, containing Fe 7%-11%;

  (3) the lead layer (layer Delta): the significant structure of the columnar structure, Fe content of 6%, non-toxic, corrosion resistance, the hardness value of 179DPN;

  (4) pure zinc layer (layer Eta): dense six party system, deformation processing is not easy to rupture, zinc purity of 98.5%, the hardness value is 70DPN;

  (5) high zinc phosphate coating: good corrosion resistance, and enhance the adhesion of coating and substrate;

  (6) Akesu: Nobel color from molecular high-temperature curing layer: excellent corrosion resistance and impact resistance, excellent anti UV, anti oxidation and surface self-cleaning performance, the color change rate of 15 years is less than 5%.

  Two, characteristics

  Zinc steel barrier has the following characteristics:

  1, free welding assembly design, quick and easy installation.

  The 2 and four layer anti-corrosion treatment, more than twenty years of life, to solve the traditional products within a short period of time, rust powder, cracking and other issues, from the maintenance and update costs.

  3, good decorative, rich colors, to meet the individual needs of different customers on the product.

  4, environmental protection, do not pollute the environment, to solve the problem of pollution of ordinary products.

  5, good flexibility, the base material of the steel and flexibility to make the barrier products have better impact resistance.

  6, the electrostatic spraying process of imitation enamel guardrail surface, the zinc steel guardrail products has a good self-cleaning performance, rain and spray wash to clean as new.

  7, buried installation and anchor plate installation, saving building infrastructure costs, saving land resources.

  8, good weather resistance, salt spray resistance and heat resistance, suitable for the use of different regions.

  7、下埋式的安装方式和地脚板式安装,即节省了您的建筑基础费用,又节省了土地资源。

  8、良好的耐候性、耐盐雾性及耐湿热性能,适合不同地域的使用。
