球墨铸铁井盖有哪些优越性呢?下面就向大家介绍一下球墨铸铁井盖优越:

What are the advantages of ductile iron manhole cover? Now I'd like to introduce the advantages of ductile iron well cover

1、由于球墨铸铁的球状石墨微观结构,在减弱振动能力方面,球墨铸铁优于铸钢,因此更加有利于降低应力。选择球墨铸铁的一个重要的原因在于球墨铸铁比铸钢成本低。球墨铸铁的低成本使得这种材料更加受欢迎,铸造效率更高,也较少了球墨铸铁的机加工成本。

1。 Due to the spheroidal graphite microstructure of ductile iron, ductile iron is better than cast steel in reducing vibration capacity, so it is more conducive to reducing stress。 One of the important reasons for choosing ductile iron is that the cost of ductile iron is lower than that of cast steel。 The low cost of ductile iron makes this material more popular, casting efficiency is higher, and machining cost of ductile iron is less。

2、球墨铸铁的强度和铸钢的强度是可比的。球墨铸铁具有更高的屈服强度,其屈服强度低为40k,而铸钢的屈服强度只有36k。在大部分市政应用领域,如:水、盐水、蒸汽等,球墨铸铁的耐腐蚀性和抗氧化性都超过铸钢。

2。 The strength of ductile iron is comparable to that of cast steel。 The yield strength of ductile iron is higher than that of cast steel, which is 40K lower than that of cast iron。 In most municipal applications, such as water, brine, steam, etc。, the corrosion resistance and oxidation resistance of ductile iron are better than that of cast steel。

3. Due to the different preparation methods, the properties of steel fiber are very different, such as the tensile strength of cold drawn steel wire is 800-2000mpa, the tensile strength of cold rolled steel strip shear method is 600-900mpa, the tensile strength of ingot milling method is 700MPa; although the liquid steel condensation method is 380MPa, it is suitable for the production of heat-resistant fiber.

4、为增强砂浆或混凝土而加入的、长度和直径在一定范围内的细钢丝。常用截面圆形的长直钢纤维,其长度为10~60毫米,直径为0.2~0.6毫米,长径比为50~100。为增加纤维和砂浆或混凝土的界面粘结,可选用各种异形的钢纤维,其截面有矩形、锯齿形、弯月形的;截面尺寸沿长度而交替变化的;波形的;圆圈状的;端部放大的或带弯钩的等。

4。 Fine steel wire with length and diameter within a certain range added for strengthening mortar or concrete。 The long straight steel fiber with round cross section is commonly used。 Its length is 10 ~ 60 mm, diameter is 0。2 ~ 0。6 mm, and length diameter ratio is 50 ~ 100。 In order to increase the interface bonding between fiber and mortar or concrete, various special-shaped steel fibers can be selected, including rectangular, serrated, crescent shaped cross section, alternating section size along the length, wavy, circular, enlarged end or with hook, etc。

1、防盗性好:

1. Good security:

本产品采用钢纤维复合材料。经高温模压而成,因无二次利用价值,具用自然防盗的特点。

This product is made of steel fiber composite material。 It is moulded at high temperature and has the characteristics of natural anti-theft because it has no secondary use value。

2 、方便美观:

2。 Convenient and beautiful:

同规格产品重量只有铸铁盖板的三分之一,给安装、检查维护带来了很大的方便,并根据客户要求生产各种规格及颜色的产品,即便于管理,又美化城市。

The weight of products of the same specification is only one third of that of cast iron cover plate, which brings great convenience to installation, inspection and maintenance. According to the requirements of customers, we can produce products of various specifications and colors, which not only beautify the city, but also manage it.

3、寿命长:

3。 Long life:

不怕酸碱腐蚀,不生锈,电绝缘,耐磨、耐侯。

Not afraid of acid and alkali corrosion, no rust, electrical insulation, wear resistance, weather resistance.

4、精度高:

4。 High precision:

由于该产品是经高温模压成型,盖座合缝间隙较小,克服了铸铁。

As the product is molded at high temperature, the gap between cover and seat is small, which overcomes the problem of cast iron。

5、铸铁井盖没有回收价值,这是因为铸铁井盖采取不饱和树脂、玻纤等材料及钢筋骨架,经特别生产工艺复合而成。树脂的成分也有天然与合成之分。

5. Cast iron well cover has no recycling value, because cast iron well cover is made of unsaturated resin, glass fiber and steel framework by special production process. The composition of resin can be divided into natural and synthetic.

铸铁井盖原料之树脂,一般认为是植物组织的正常代谢产物或分泌物,常和挥发油并存于植物的分泌细胞,树脂道或导管中,尤其是多年生草本植物心材部位的导管中。由多种成分组成的混杂物,通常为无定型固体,外表微有光泽,球墨铸铁井盖篦子特点质硬而脆,少数为半固体。不溶于水,也不吸水膨胀,易溶于醇,乙醚,氯仿等大多数有机溶剂。加热软化,后熔融,焚烧时有浓烟,并有特别的香气或臭气。

The resin used as the raw material of cast iron manhole cover is generally considered as the normal metabolite or secretion of plant tissue。 It often coexists with volatile oil in the secretory cells, resin ducts or ducts of plants, especially in the ducts of heartwood of perennial herbs。 The mixture composed of various components is usually amorphous solid with slightly glossy appearance。 The grate of nodular cast iron well cover is hard and brittle, and a few are semi-solid。 It is insoluble in water and does not swell。 It is easily soluble in most organic solvents such as alcohol, ether, chloroform, etc。 It is softened by heating and then melted。 When burned, it has strong smoke and special aroma or odor。

6、铸铁井盖的原料之树脂,分为天然树脂和合成树脂两大类。合成树脂是指由简单有机物,经化学合成,或某些天然产物经化学反应,而得到的树脂产物,合成树脂是塑料的重要成分。天然树脂是指由自然界中动植物,分泌物所得的无定形有机物质,如松香、琥珀、虫胶等。

6。 The raw materials of cast iron well cover are divided into natural resin and synthetic resin。 Synthetic resin is a kind of resin product obtained by chemical synthesis of simple organic matter or chemical reaction of some natural products。 Synthetic resin is an important component of plastics。 Natural resin refers to the amorphous organic substances obtained from the secretions of animals and plants in nature, such as rosin, amber, shellac, etc。

井盖一般采用圆形,主要用于遮盖道路或家中深井,防止人或者物体坠落。众所周知,井盖在实际使用过程中,也会发生噪音,这该怎么解决呢?我们首先要找到井盖噪音的根源,然后针对性的将其去除。

The well cover is generally round, which is mainly used to cover the road or deep well at home to prevent people or objects from falling。 As we all know, in the actual use of well covers, noise will also occur。 How to solve this problem? We first need to find the source of the noise, and then targeted to remove it。

7、一般,一个完整的井盖装置是由井盖座和井盖构成的,在应用过程中,由于受到车辆或重物的碾压,井盖座和井盖之间,会发生松动,并产生间隙。由此一来,井盖座和井盖撞击,就会有噪音产生,严重影响到周围环境及居民生活,而且也带来了安全隐患。

7. Generally, a complete well cover device is composed of a well cover seat and a well cover. In the application process, due to the rolling of vehicles or heavy objects, the well cover seat and the well cover will become loose and produce a gap. As a result, the impact between the well cover seat and the well cover will produce noise, which will seriously affect the surrounding environment and residents' life, and also bring about potential safety hazards.

8、针对这我们可在井盖装置下端与井口的配合处,固定设置一个防震橡胶圈,用以加强井盖的稳固性,这样产生噪音的可能也大大减少了,也可以通过对井盖材料,加以改进并改善。

8。 In view of this, we can fix a shockproof rubber ring at the matching place between the lower end of the well cover device and the wellhead to strengthen the stability of the well cover。 In this way, the possibility of noise generation is greatly reduced。 We can also improve and improve the material of the well cover。
