燕趙新聞網(wǎng)今日?qǐng)?bào)道:水泥砂漿防腐鋼管的施工有兩種方法。一是地面離心法。主要適同于DN400口徑以下的管道內(nèi)襯施工。而是地下噴涂法,主要適用于DN700口徑以上的管道在地下防腐施工。 水泥沙漿襯里同金屬管道分別為兩種材質(zhì),砂漿對(duì)管道的結(jié)合力如何?尤其是鋼管內(nèi)防腐層是否會(huì)在運(yùn)輸,安裝等外力作用下脫落?即其機(jī)械強(qiáng)度怎樣?根據(jù)國(guó)外實(shí)驗(yàn)的數(shù)據(jù)可以證明其機(jī)械強(qiáng)度。 鋼管在受外壓變形變扁平時(shí),砂漿會(huì)產(chǎn)生“發(fā)狀”裂縫,但要砂漿從管壁上剝離卻是非常困難的,在口徑DN800毫米壁厚為7.1毫米的鋼管上,截取一米長(zhǎng)的管段,涂襯11毫米厚的砂漿涂層,當(dāng)扁平量7-8毫米時(shí),可以看到“發(fā)狀”裂縫的出現(xiàn)。當(dāng)扁平量增加到50毫米時(shí),裂縫逐漸增加到邊部全管段,實(shí)驗(yàn)結(jié)果,管徑1%的扁平量時(shí)產(chǎn)生“發(fā)狀”裂縫,當(dāng)扁平量為6-9%的場(chǎng)合,沙漿涂層開始崩裂,達(dá)到管徑30%時(shí)剝落。這在施工中是決不允許發(fā)生的。據(jù)測(cè)定,在DN1100管子上,*小扁平量為15毫米,DN1800管上為21毫米。由此可見,管徑的增大,產(chǎn)生裂縫的扁平量也隨之增大。水泥沙漿襯里用普通的水泥與一定粗細(xì)的黃沙,添加劑,按照設(shè)計(jì)的配合比,拌制成砂漿,通過專用的施工機(jī)械設(shè)備,涂敷到管道內(nèi)壁上,形成一定厚度的砂漿涂層,凝固后成為襯里。水泥砂漿襯里,依靠自身的結(jié)合力與管道壁的支撐,其結(jié)構(gòu)均勻致密,堅(jiān)硬牢固,如果在沙漿表面再涂刷環(huán)氧樹脂,其通水后的粗糙系數(shù)還可再降低。水泥砂漿襯里不僅是物理性能上簡(jiǎn)單的阻隔屏障,而是通過水泥砂漿襯里的化學(xué)性能,保護(hù)管道。砂漿層與管道結(jié)合,在管壁層面形成一個(gè)PH值高達(dá)12的鈍化區(qū)域,通水后,水滲入水泥砂漿,富含堿性成分,使水到達(dá)管壁時(shí)不再具有腐蝕性。、

Yanzhao news network reported today: there are two methods for the construction of cement mortar anticorrosive steel pipe. One is the ground centrifugation method. It is mainly suitable for pipe lining construction below DN400 diameter. Instead, the underground spraying method is mainly used for underground anticorrosion construction of pipelines with DN700 diameter. Cement mortar lining and metal pipe are respectively two kinds of materials. How does mortar combine with pipes? In particular, will the internal anticorrosive coating of the steel pipe fall off under the action of transportation, installation and other external forces? What is its mechanical strength? According to the data from abroad, the mechanical strength can be proved. When the steel tube is deformed and flattened by external compression, the "hairlike" cracks will occur, but it is very difficult for the mortar to peel off the pipe wall. On a steel tube with a diameter of DN800mm and a wall thickness of 7.1 mm, one meter long pipe is cut off and coated with 11 mm thick mortar coating. When the flatness is 7-8 mm, the "hairlike" cracks can be seen. The appearance of a seam. When the flatness is increased to 50mm, the cracks gradually increase to the side of the whole pipe. The experimental results show that the "hairlike" cracks occur when the flatness of 1% pipe diameter is increased. When the flatness is 6-9%, the mortar coating begins to crack and peels off when the pipe diameter reaches 30%. This is not allowed in construction. According to the measurement, on the DN1100 pipe, the small flat volume is 15 millimeters, and the DN1800 tube is 21 millimeters. It can be seen that the increase of pipe diameter leads to the increase of the flat volume of cracks. The cement mortar lining is made by mixing ordinary cement with yellow sand of a certain thickness and additives according to the designed mix proportion. The mortar is coated on the inner wall of the pipeline through special construction machinery and equipment to form a certain thickness of mortar coating, which becomes the lining after solidification. Cement mortar lining, depending on its own binding force and pipe wall support, its structure is uniform and compact, hard and firm, if the surface of the mortar is re-coated with epoxy resin, its roughness coefficient can be further reduced after watering. Cement mortar lining is not only a simple barrier in physical properties, but also a chemical property of cement mortar lining to protect pipelines. When the mortar layer is combined with the pipeline, a passivation zone with a PH value of up to 12 is formed on the pipeline wall. After water flowing through the pipeline, the water seeps into the cement mortar and is rich in alkaline components, which makes the water no longer corrosive when it reaches the pipeline wall.
水泥砂漿面料防腐鋼管技術(shù),不只可以運(yùn)用于新管道的防腐,也可以用在舊管道改造方面。由于曩昔排設(shè)的金屬給水管道,在內(nèi)壁僅刷一層瀝青,在管內(nèi)水流長(zhǎng)時(shí)間沖刷和厭氧細(xì)菌吞噬下,發(fā)作了腐蝕與結(jié)垢。有的當(dāng)?shù)劁P垢高達(dá)十多公分。通水截面因此縮小。水泥砂漿面料防腐鋼管摩阻系數(shù)由正本的0上,直接影響水廠的水質(zhì)與供水的能耗。水泥砂漿防腐鋼管標(biāo)準(zhǔn)及其理論重量,水泥砂漿一般坐在螺旋鋼管內(nèi)壁,螺旋鋼管重量人們都會(huì)算但是內(nèi)襯水泥砂漿的重量一般都不理解。鋼管撞車時(shí)分一般要裝噸位的,所以水泥砂漿重量就很重要了。
防腐螺旋鋼管防腐介質(zhì):
IPN8710防腐螺旋鋼管內(nèi)腐蝕介質(zhì)種類較多,有酸、堿、鹽、氧化劑及水蒸氣等,涂料必須具有化學(xué)惰性、耐酸堿鹽腐 蝕,涂膜應(yīng)結(jié)構(gòu)致密,防水滲透性好,附著力強(qiáng)、堅(jiān)韌豐滿。
水泥砂漿在建筑工程中,一是基礎(chǔ)和墻體砌筑,用做塊狀砌體材料的粘合劑,比如砌毛石、紅要用水泥砂漿;二是用于室內(nèi)外抹灰。水泥砂漿在使用時(shí),還要經(jīng)常摻入一些添加劑如微沫劑、防水粉等,以改善它的和易性與粘稠度。水泥砂漿里按比例加入石子,就成為凝土。我公司所能加工的管徑范圍是Φ325~Φ2220。內(nèi)襯水泥砂漿防腐鋼管是采用成型工藝,將攪拌好的水泥砂漿,在清理過的管道內(nèi)壁上按照設(shè)計(jì)厚度要求,分一次或多次涂襯,經(jīng)過一定時(shí)間養(yǎng)護(hù)后,形成一個(gè)與管內(nèi)壁緊密結(jié)合的高強(qiáng)度圓殼體內(nèi)襯層。一般直徑800以上的大口徑管道做水泥砂漿防腐時(shí)需加入鐵絲網(wǎng)以增強(qiáng)水泥砂漿的堅(jiān)固性,防止裂縫脫落。利用水泥砂漿特有的堿性,使管道內(nèi)表面形成鈍化膜而得到保護(hù)的技術(shù),已被國(guó)內(nèi)外水管道的內(nèi)防腐廣泛采用。在施工中,通過加入添加劑,提高養(yǎng)護(hù)期的溫度、濕度則可以有效減少施工初期產(chǎn)生的裂縫。另外,水泥砂漿的*終收縮期為1-2年,鋼管投入運(yùn)行后,水泥砂漿長(zhǎng)期在水中繼續(xù)硬結(jié),可使裂縫自動(dòng)彌合,不影響防腐蝕的效果。


Cement mortar fabric anticorrosion steel pipe technology, not only can be used in the new pipeline anticorrosion, but also can be used in the old pipeline transformation. Because of the metal water supply pipeline laid in the past, only a layer of asphalt is brushed on the inner wall, corrosion and scaling occur when the water in the pipeline is washed away for a long time and is swallowed by anaerobic bacteria. Some local rust scale is as high as more than 10 centimeters. The cross section of water is reduced. Friction coefficient of cement mortar fabric anticorrosive steel pipe is above 0, which directly affects water quality and energy consumption of water supply. Cement mortar anti-corrosion steel pipe standard and its theoretical weight, cement mortar generally sitting in the inner wall of spiral steel pipe, spiral steel pipe weight will be calculated, but the weight of cement mortar lining is generally not understood. When steel pipe crashes are usually loaded with tonnage, the weight of cement mortar is very important.
Anticorrosive medium for anticorrosive spiral steel pipe:
IPN8710 anticorrosive spiral steel pipe has many kinds of corrosive medium, such as acid, alkali, salt, oxidant and water vapor. The coating must be chemical inert, acid and alkali salt resistant. The coating should be compact, waterproof and permeable, strong adhesion, toughness and fullness.
Cement mortar in construction projects, one is the foundation and wall masonry, used as a block of masonry materials adhesive, such as rubble, red to use cement mortar; the other is used for indoor and outdoor plastering. In order to improve the workability and viscosity of cement mortar, some additives, such as microfoam agent and waterproof powder, are often added to it. By adding proportions of stones into cement mortar, it becomes condensate. The diameter of the pipe that our company can process is from 325 to 2220. The anti-corrosion steel pipe lined with cement mortar is formed by adopting the molding technology, mixing the cement mortar well, coating the inner wall of the cleaned pipe one or more times according to the design thickness requirements, and forming a high-strength circular shell inner lining closely combined with the inner wall of the pipe after a certain period of maintenance. Generally, when the large diameter pipeline with diameter over 800 is used for cement mortar anticorrosion, wire mesh should be added to enhance the firmness of cement mortar and prevent cracks from falling off. The technology of using cement mortar to form passive film to protect the inner surface of pipeline has been widely used for internal corrosion protection of water pipeline at home and abroad. In the construction, by adding additives, the temperature and humidity during the curing period can be increased to effectively reduce the cracks in the initial stage of construction. In addition, the final shrinkage period of cement mortar is 1-2 years. After the steel pipe is put into operation, the cement mortar will continue to harden in water for a long time, which can make the cracks close automatically without affecting the anticorrosion effect.
