球墨鑄鐵井蓋有哪些優越性呢?下面就向大家介紹一下球墨鑄鐵井蓋優越:

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

1、由于球墨鑄鐵的球狀石墨微觀結構,在減弱振動能力方面,球墨鑄鐵優于鑄鋼,因此更加有利于降低應力。選擇球墨鑄鐵的一個重要的原因在于球墨鑄鐵比鑄鋼成本低。球墨鑄鐵的低成本使得這種材料更加受歡迎,鑄造效率更高,也較少了球墨鑄鐵的機加工成本。

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、球墨鑄鐵的強度和鑄鋼的強度是可比的。球墨鑄鐵具有更高的屈服強度,其屈服強度低為40k,而鑄鋼的屈服強度只有36k。在大部分市政應用領域,如:水、鹽水、蒸汽等,球墨鑄鐵的耐腐蝕性和抗氧化性都超過鑄鋼。

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、因制取方法的不同鋼纖維的性能有很大不同,如冷拔鋼絲拉伸強度為800-2000MPa、冷軋帶鋼剪切法拉伸強度為600-900MPa、鋼錠銑削法為700MPa;鋼水冷凝法雖為380MPa,但是適合生產耐熱纖維。

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、為增強砂漿或混凝土而加入的、長度和直徑在一定范圍內的細鋼絲。常用截面圓形的長直鋼纖維,其長度為10~60毫米,直徑為0.2~0.6毫米,長徑比為50~100。為增加纖維和砂漿或混凝土的界面粘結,可選用各種異形的鋼纖維,其截面有矩形、鋸齒形、彎月形的;截面尺寸沿長度而交替變化的;波形的;圓圈狀的;端部放大的或帶彎鉤的等。

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、防盜性好:

1. Good security:

本產品采用鋼纖維復合材料。經高溫模壓而成,因無二次利用價值,具用自然防盜的特點。

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 、方便美觀:

2. Convenient and beautiful:

同規格產品重量只有鑄鐵蓋板的三分之一,給安裝、檢查維護帶來了很大的方便,并根據客戶要求生產各種規格及顏色的產品,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、壽命長:

3. Long life:

不怕酸堿腐蝕,不生銹,電絕緣,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:

由于該產品是經高溫模壓成型,蓋座合縫間隙較小,克服了鑄鐵。

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

5、鑄鐵井蓋沒有回收價值,這是因為鑄鐵井蓋采取不飽和樹脂、玻纖等材料及鋼筋骨架,經特別生產工藝復合而成。樹脂的成分也有天然與合成之分。

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.

鑄鐵井蓋原料之樹脂,一般認為是植物組織的正常代謝產物或分泌物,常和揮發油并存于植物的分泌細胞,樹脂道或導管中,尤其是多年生草本植物心材部位的導管中。由多種成分組成的混雜物,通常為無定型固體,外表微有光澤,球墨鑄鐵井蓋篦子特點質硬而脆,少數為半固體。不溶于水,也不吸水膨脹,易溶于醇,乙醚,氯仿等大多數有機溶劑。加熱軟化,后熔融,焚燒時有濃煙,并有特別的香氣或臭氣。

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、鑄鐵井蓋的原料之樹脂,分為天然樹脂和合成樹脂兩大類。合成樹脂是指由簡單有機物,經化學合成,或某些天然產物經化學反應,而得到的樹脂產物,合成樹脂是塑料的重要成分。天然樹脂是指由自然界中動植物,分泌物所得的無定形有機物質,如松香、琥珀、蟲膠等。

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.

井蓋一般采用圓形,主要用于遮蓋道路或家中深井,防止人或者物體墜落。眾所周知,井蓋在實際使用過程中,也會發生噪音,這該怎么解決呢?我們首先要找到井蓋噪音的根源,然后針對性的將其去除。

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,一個完整的井蓋裝置是由井蓋座和井蓋構成的,在應用過程中,由于受到車輛或重物的碾壓,井蓋座和井蓋之間,會發生松動,并產生間隙。由此一來,井蓋座和井蓋撞擊,就會有噪音產生,嚴重影響到周圍環境及居民生活,而且也帶來了安全隱患。

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、針對這我們可在井蓋裝置下端與井口的配合處,固定設置一個防震橡膠圈,用以加強井蓋的穩固性,這樣產生噪音的可能也大大減少了,也可以通過對井蓋材料,加以改進并改善。

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.
