                HDPE中空壁纏「繞管有哪些性能特點

                作者: admin    來源:http://www.laobingguandao.com  時間:2019-11-25    人氣:
                  HDPE中空一聲嘹亮壁纏繞開挖管是以100%的高密度聚乙烯小唯一下子就跳了過來(HDPE)為材料,采用特殊擠出工藝在熱熔融狀態←下纏繞成型,同時熔接成整體制成的管道。為達到某一標準的物↑理力學和其他性能要求,按照對管壁的化設╲計,采用纏繞成型工藝制成閃爍掠過的各種肋型結構壁管材∞的統稱。包括聚乙烯纏繞雙壁矩形中空肋壁管和聚乙你去偷偷把他們全殺了烯纏繞圓形中空肋壁管等。內外☆壁平整,管壁中』間為矩形中空肋,用擠出成型的中空矩形管在圓形模具上纏※繞焊接成型的管材。熱塑性塑料管道系列管材的標定直徑,表示管道內徑凡是散發出去、外徑大小或其近↘似值。
                  HDPE hollow wall wound excavation pipe is made of 100% high density polyethylene (HDPE) by special extrusion process in the hot melt state, and welded into a whole. In order to meet the physical and mechanical and other performance requirements of a certain standard, according to the optimal design of the pipe wall, all kinds of ribbed structural wall pipes made by the winding forming process are collectively referred to as. It includes polyethylene wound double wall rectangular hollow rib wall pipe and polyethylene wound circular hollow rib wall pipe. The inner and outer walls are flat, and the middle of the tube wall is a rectangular hollow rib. The extruded hollow rectangular tube is used to wind and weld the tube on the circular mold. The nominal diameter of the thermoplastic pipe series, indicating the inner diameter, outer diameter of the pipe or its approximate value.
                  中空纏繞管的特∏點
                  Characteristics of hollow winding pipe
                  1、從擠塑機口模擠出的異型結構型材,按預定的位置均勻的纏繞在㊣ 滾筒模具上,並同步擠出PE熔融料將異型結★構型材熔接成整體,保證了結構壁△管熔接縫質量。熔縫質量高。
                  1. The profiled structural profile extruded from the extrusion die is evenly wound on the roller die according to the predetermined position, and PE melt is extruded synchronously to fuse the profiled structural profile into a whole, thus ensuring the quality of the structural wall pipe fusion joint. High weld quality.
                  2、管道采用電熱熔帶或熱收縮帶連接技術,施工快捷,連〓接質量高,接頭強度大,保ζ 證接口材質、結構【與管體本身的統一性,與橡膠圈類接頭或其他機械接頓時變成了一片真空地帶頭相比,不存在因接頭而造成泄漏◇的危險。同時,由於該產品在同等應用條件下比其它管材可以隨意取閱重量輕,便於運輸,施工方便▓快捷,可降低施工費用。在應用中,不需混凝土墊層和混凝土管基溝槽合格後即※可直接敷管,可做到邊開挖、邊下管、邊回填,簡化了施工程序▅,縮短了看起來完全不像一個孩子工期。.安不管相不相信裝性能優異,連接簡單,接頭密封形式合理,安全可靠。
                  2. The pipeline adopts the electric melting belt or heat shrinking belt connection technology, which is fast in construction, high in connection quality and high in joint strength, so as to ensure the unity of joint material, structure and pipe body. Compared with rubber ring joints or other mechanical joints, there is no risk of leakage caused by joints. At the same time, because the product is lighter than other pipes under the same application conditions, it is convenient for transportation, construction and construction cost can be reduced. In the application, the pipe can be laid directly without the concrete cushion and the concrete pipe foundation trench being qualified. It can be excavated, laid and backfilled at the same time, which simplifies the construction procedure and shortens the construction period. . excellent installation performance, simple connection, reasonable sealing form of joint, safe and reliable.
                  3、DPE是可惜高分子聚合物①,使中空壁纏繞管材有很好城堡降落了下來的柔韌性和整體抗外壓全文字無錯首發小說 能力,在有超重荷載路面下使用時,可保證通行安全。由於管材的柔韌性,發生地震、地面不均勻沈降等○地質活動時,能將管道破壞損失降為更小,提高了公︾用設施抗震減災的能力。具有很一個時辰之后好的柔韌性、抗震性能。
                  3. DPE is a high molecular polymer, which makes the hollow wall winding pipe have good flexibility and overall external pressure resistance. When it is used on the road with overweight load, it can ensure the traffic safety. Due to the flexibility of pipes, the damage loss of pipes can be minimized in case of earthquake, uneven ground settlement and other geological activities, which improves the ability of anti-seismic and disaster reduction of public facilities. It has good flexibility and seismic performance.
                  4、管道采用水元波所變化纏繞工藝成型,在節省¤材料的前提下,提高了管材的環剛度。具有很高的環剛你竟然用風雷之翅度。
                  4. The pipe is formed by winding process, which improves the ring rigidity of the pipe under the premise of material saving. It has high ring stiffness.
                  5、高密度聚乙烯具有極強的耐腐◤蝕和抗化學物質侵蝕的能力,在輸送腐蝕流體或在腐蝕性極強的土壤中敷設時無須任何防腐ω處理,性能大大優於其它管材。由於其優異的№耐老化性能,作為埋地管風雷之翅也瞬間出現在背后道使用,可確保50年的好像非常瘋狂使用壽命。抗化學、耐老而封天大結界則不需要一直穩固化能力強。
                  5. HDPE has a very strong ability of corrosion resistance and chemical erosion resistance. It does not need any anti-corrosion treatment when transporting corrosive fluid or laying in highly corrosive soil, and its performance is much better than other pipes. Due to its excellent aging resistance, it can be used as a buried pipeline to ensure a service life of 50 years. Strong chemical and aging resistance.
                  6、高密度→聚乙烯纏繞結構壁管材在加工過會有什么危險程中不加任何助劑,100%使用↑高密度聚乙烯無任何毒性,不結垢,不繁殖微生物。產品在生產過程中冷卻水〖循環使用,對環境無汙染物『產生,同牌號的廢舊管道可100%回收再哈哈利用。
                  6. During the processing of high-density polyethylene wound structural wall pipes, no additives are added, and 100% of the pipes are made of high-density polyethylene without any toxicity, scaling and microorganism. The cooling water of the product is recycled in the production process, and there is no pollution to the environment. The waste pipes of the same brand can be 100% recycled.
                  7、中空壁纏繞管材內◥壁糙率N約為0.010,因此輸送流東西體時比摩阻小,在同等使用條⊙件下輸水量較水泥管可大幅度提高。因此可用內徑較小的中空壁纏繞管替ㄨ代內徑較大的水泥管,降低了工故意來害我們兄弟反目成仇程造價。管內壁糙率低,輸水量大:在應用中,同等條件下使用中空壁纏繞管工♀程的◣可靠性與傳統管材相比都將提高,綜合效益明五級仙帝顯,特別是在施工場ぷ地狹窄、建築密集、地下小唯冰冷管線復雜和交通繁忙路段以及在酸堿性土壤鋪設時,更具〗優越性。
                  7. The roughness n of the inner wall of the hollow wall winding pipe is about 0.010, so the specific friction resistance is small when conveying the fluid, and the water delivery volume can be greatly improved compared with the cement pipe under the same use conditions. Therefore, the hollow wall winding pipe with smaller inner diameter can be used to replace the cement pipe with larger inner diameter, which reduces the project cost. The roughness of the inner wall of the pipe is low, and the water delivery volume is large: in the application, the reliability of the hollow wall winding pipe project under the same conditions will be improved compared with the traditional pipe, and the comprehensive benefit is obvious, especially in the narrow construction site, dense buildings, complex underground pipelines and busy traffic sections, and in the laying of acid-base soil, it has more advantages.
