Title
(EN) Scale inhibition pipe and production process thereof
(ZH) 一种阻垢管及其生产工艺
Abstract
(EN)
The invention discloses a scale inhibition pipe and a production process thereof, wherein the production process includes the following steps: S1, taking a PP and/or PE raw material with super high molecular weight, and sintering the PP and/or PE raw material by semi-melt die pressing to form an outer sleeve filter core; S2, taking a PP and/or PE raw material with super high molecular weight, andsintering the PP and/or PE raw material by semi-melt die pressing to form an inner sleeve filter core; and S3, assembly the outer sleeve filter core and the inner sleeve filter core to form a tube body, then pouring an FOF scale inhibitor between the outer sleeve filter core and the inner sleeve filter core, and sintering by semi-melt die pressing to form the scale inhibition pipe. The scale inhibitor in the whole scale inhibition pipe is distributed more uniformly, and the scale inhibition pipe has good scale inhibition effect by slowly releasing the FOF scale inhibitor and can continuously play a role in inhibiting scale. At the same time, the FOF scale inhibitor cannot change the water quality after entering water, has little influence on the pH of raw water, and is conducive to maintaining the characteristics of raw water.

本发明取一种阻垢管及其生产工艺,其中,所述生产工艺包括如下步骤:S1、取超高分子量的PP和/或PE原材料,将PP和/或PE原材料通过半熔融模压烧结形成外套滤芯;S2、取超高分子量的PP和/或PE原材料,将PP和/或PE原材料通过半熔融模压烧结形成内套滤芯;S3、将外套滤芯和内套滤芯组装形成管体,然后向外套滤芯和内套滤芯之间灌入FOF阻垢剂,并通过半熔融模压烧结形成所述阻垢管。本发明使整支阻垢管中的阻垢剂分布更加均匀,阻垢管通过缓慢释放FOF阻垢剂,具有较好的阻垢效果,并能够持续地起到阻垢的作用。同时,FOF阻垢剂入水后不会改变水质,对原水pH影响微小,有利于保持原水的特性。
