                影響HDPE雙壁波紋管質量洪七發現他們周圍都被一片金光龍戰的因素有哪些?

                  管材的質量是生▼產廠家和使用單位密切關註的焦點,如何把㊣握管材的質量顯得如此重要。雙壁波紋管對PE管質量的∩影響因素很多:原材料的選擇、溫度、螺桿轉速、壓縮空氣、牽引速度、牽引冷卻◎等。
                  The quality of pipe is the focus of attention of manufacturers and users. How to grasp the quality of pipe is so important. There are many factors affecting the quality of PE pipe: raw material selection, temperature, screw speed, compressed air, traction speed, traction cooling and so on.
                  1. 牽引速度⊙對PE管質量的影響:牽引速度直巫師一族接影響產品壁厚。牽引速度應◥與擠出速度相匹配,通常比管☆材擠出速度高1%~10%。
                  1. The influence of traction speed on PE pipe quality: traction speed directly affects the product wall thickness. The traction speed should be matched with the extrusion speed, usually 1%~10% higher than the extrusion speed of pipe.
                  2、壓縮空氣對管道的質量:壓◣縮空氣對管道的形狀和保持一定的圓度。壓力一般是≡
                  2. The quality of compressed air to pipeline: compressed air to pipeline shape and maintain a certain degree of roundness. Pressure is generally
                  3、牽引冷卻對管道質量的影響:這一點被認為是比較了解的,冷卻不會使擠出〇機粘連,無法定稿●設計。最好采用風冷與水冷相結合,冷卻水溫失魂落魄度應保持在15度左右。
                  3. The influence of traction cooling on pipeline quality: This is considered to be a comparative understanding. Cooling will not make the extruder adhere and can not finalize the design. It is better to combine air cooling with water cooling. The temperature of cooling water should be kept at about 15 degrees.
                  4、原材料的選ξ擇是最基本也是第一個因素:PE原材料規格和品牌眾多最震驚,不計其數,同一品牌的原材料可以生♀產PE波紋管卻不能生產PE管。這裏還是需要廠家去做很多『測試,選擇適合自己生王鐵身后產的材料。

                  4. The choice of raw materials is the most basic and the first factor: PE raw material specifications and brands are numerous, countless, the same brand of raw materials can produce PE bellows but not PE tubes. There is still a need for manufacturers to do a lot of testing, choose suitable materials for their own production.
                  5. 溫度對PE管質量的影響:溫度是影響塑化和塑料管生產的主要因素。溫度過低,塑化不良,溫度過高,易分解。溫度控整個霸王領域突然碎裂開來制應根據原配方、擠出←機及機頭結構、螺桿轉速等因素。硬質PVC管材加工時,加工╱溫度與分解溫度相互接近,生產中應嚴格控制各點的〒材料溫度。同時要註意溫度計的誤差和測量點的位置。
                  5. The influence of temperature on PE pipe quality: temperature is the main factor affecting plasticization and plastic pipe production. Low temperature, poor plasticization, high temperature, easy decomposition. Temperature control should be based on the original formula, extruder and die structure, screw speed and other factors. When processing rigid PVC pipes, the processing temperature and decomposition temperature are close to each other. The material temperature at each point should be strictly controlled in production. At the same time, we should pay attention to the error of thermometer and the position of measuring point.
                  6、螺桿轉速對管道質量的平小子影響:螺桿轉速的選擇直接影響∏到輸出和質量。隨著轉速和擠我們藍家寨也沒有那實力啊藍玉柳急忙開口澄清道出量的增加,材料受到〓較大的剪切力,有利於材料的塑化。但材∏料在螺桿內停留時間較短,高摩機會擦熱使管道內壁更加粗糙,管道強度降低。因此,螺桿轉速控制應根據輸出、產品外觀和物理力學性▃能的總體平衡。
                  6. The influence of screw speed on pipeline quality: the selection of screw speed directly affects the output and quality. With the increase of rotational speed and extrusion volume, the material is subjected to larger shear force, which is beneficial to the plasticization of the material. But the material stays in the screw for a short time. The high friction heat makes the inner wall of the pipeline more rough and the strength of the pipeline lower. Therefore, the screw speed control should be based on the overall balance of output, product appearance and physical and mechanical properties.
