Description
技术领域
本发明涉及一种用作排水管或导水管的螺线管,更具体地说,本发明涉及一种粘合螺线管的方法,其中,在制造螺线管时,通过卷绕机将粘接树脂包覆在具有空腔的矩形剖面的四周或者填充有填料,将粘接树脂完全包覆在形成H横梁形的矩形剖面的表面上,从而使得螺线管能牢牢地粘合。
背景技术
如图1和图2所示,通过将粘结树脂涂覆在具有空腔的矩形剖面2的一侧,通过卷绕机卷绕剖面,使得剖面2彼此粘结,并通过辊子挤压剖面形成I横梁形,从而形成一个常规的螺线管1。
也就是说,在常规的螺线管1中,粘结树脂仅仅涂覆在相邻的剖面2之间,从而形成具有I横梁形的粘结树脂层3。
因此,常规的螺线管1仅仅在相邻的剖面2的表面之间具有I横梁形粘结树脂层3,粘合特性很弱。相应的,当施加外部冲击时,在剖面2和粘结树脂层3之间的边界表面处产生裂纹,他们很容易断裂并彼此分开。
此外,当用作排水管或导水管的螺线管1断裂时,污水渗入土壤,严重污染土壤和地下水,并导致地面沉降。
本发明的公开
为了解决上述问题,本发明的目的是提供一种用于螺线管的粘结方法,在该方法中,粘结树脂层整体形成为具有H横梁形,使得螺线管能承受外部压力、冲击和负载,不容易断裂,并具有优良的刚性系数。此外,也可以防止由于管道破裂造成的环境污染。很经济地延长了产品的寿命。与常规的产品相比较,产品的外观很美观。
本发明的另一个目的是提供一种可以应用在具有空腔的矩形剖面或者填充有填料的矩形剖面上的螺线管粘结方法,通过在剖面四周完全包覆粘结树脂使得螺线管的表面很平整,可以防止污泥堆积在管道中,从而可防止管道堵塞。
为了实现上述目的,所提供的螺线管粘结方法包括如下步骤:在180-250℃下通过一个挤压装置熔化混合废旧塑料并挤压出矩形剖面,在通过卷绕机卷绕剖面之前,从一个辅助挤压装置中提供挤压出的粘结树脂以包覆剖面,围绕卷绕机卷绕粘结树脂包覆的剖面,对卷绕剖面外侧四周涂覆的粘结树脂表面进行压制,使得粘结树脂压制成在相邻的剖面之间具有H横梁形,并使剖面彼此粘结。
按照本发明的剖面可以应用在任何内部具有空间部分的中空剖面上或者内部填充有填料的填充剖面上。涂覆粘结树脂形成均匀的剖面体和粘结树脂层,完全包覆相邻剖面的表面,使得在粘结树脂层形成后,管道表面平整。

实施本发明的优选方式
下面,将参考附图详细描述本发明的一个优选实施例。
图3至图6说明了本发明的优选实施例的螺线管粘结方法。图3和图4是分别显示按照本发明的粘结方法应用在中空剖面5上时的螺线管的外观和截面结构的局部剖面透视图和局部放大剖面图。图5和图6是分别显示按照本发明的粘结方法应用在填充剖面8上时的螺线管的外观和截面结构的局部剖面透视图和局部放大剖面图。
如图所示,通过在挤压装置中提供废旧塑料并通过一个具有预定形状的冲模强行挤压材料形成矩形中空剖面5来形成本发明的螺线管。熔融的粘结树脂进入附加的辅助挤压装置的内部并被强行挤压出来以完全包覆中空剖面5。通过卷绕机卷绕涂覆有粘结树脂的中空剖面5,同时,通过辊子压制粘结树脂表面,使得粘结树脂层6形成H横梁形。
在此,不使用中空剖面5,而使用内部填充有填料10的剖面8。粘结树脂涂覆在四周并粘结填充有填料10的剖面8的表面,使得粘结树脂层9具有H横梁形。作为填料10,可使用熔化混合的废旧塑料和诸如农副产物、林副产物或粉尘之类的填料。
下面将详细描述本发明的优选实施例。
(优选实施例1)
参考图3和4,首先,在180-250℃的熔化温度范围内在一个挤压装置中熔化混合各种废塑料并通过一个矩形冲模挤压,形成中空剖面5。
同时,从附加的辅助挤压装置中挤压出粘结树脂,使以预定的直径连续卷绕的中空剖面5彼此粘结,中空剖面5完全被粘结树脂包覆。
提供此种状态的中空剖面5,并通过卷绕机卷绕。当通过卷绕机卷绕整个包覆有粘结树脂的中空剖面5时,通过辊子压制,使之彼此粘结,从而中空剖面5之间的粘结树脂层6形成H横梁形。
在上述的方法中,由于粘结螺线管4的中空剖面5的粘结树脂层6完全包覆中空剖面5,形成H横梁形,与常规的螺线管1相比较,抗冲击强度和环状刚性系数显著提高。
(优选实施例2)
在180-250℃的熔化温度范围内通过挤压装置熔化混合各种废塑料和诸如农副产品、林副产品或烟灰之类的填料以挤压出剖面8。在此,挤压的剖面8的空腔填充了与废塑料混合的填料。
由于填充有填料10的剖面8具有减缓外部冲击的特性,与按照上述实施例的中空剖面5相比较,抗冲击强度性能可进一步提高。
同时,从辅助挤压装置中挤压出粘结树脂,使以预定的直径连续卷绕的剖面8彼此粘结,使得剖面8完全被粘结树脂包覆。
将上述状态的填充剖面8提供给卷绕机卷绕。通过卷绕机卷绕所有表面包覆有粘结树脂的填充剖面8,同时,通过辊子压制,使之彼此粘结,从而使填充剖面8之间的粘结树脂层9形成H横梁形。
按照上述的方法,用于粘合螺线管7的填充剖面8的粘结树脂层9形成H横梁形,完全包覆填充剖面8,与常规的螺线管1相比较,抗冲击强度和环状刚性系数显著提高。
工业实用性
通过熔化混合材料由挤压装置形成剖面,并压制相邻剖面之间的粘结树脂以使剖面彼此粘结,通过包覆剖面形成螺线管。因此,粘合剖面的粘结树脂层具有H横梁形,从而提供一个形成均匀剖面体和粘结树脂的螺线管。
于是,由于可保持粘结树脂在剖面上的整个表面涂覆状态,不会产生不均匀部分,本发明的外观很美观。由于螺线管形成一个均匀体且保持H横梁形,与常规管相比较,粘结强度大大提高。结果是,该螺线管可很好地承受外部压力、静态负荷和动态负荷,抗冲击性和环状刚性系数显著提高。由于污泥不会累积在管道中,排水管不会堵塞。
