Problems solved by technology

[0002] At present, in the industrial water treatment process, disposable filter materials such as quartz sand and activated carbon are generally used to filter out suspended solids in water, but the filtration performance of disposable filter materials will gradually weaken over time until they fail, and cannot be reused. The service life is short, in order to ensure a better filtering effect, it is generally necessary to replace it before the performance drops to 50%, resulting in waste

Abstract

The invention discloses a composite membrane filtration pipe and a preparation method thereof. The composite membrane filtration pipe is prepared from the following components in percentage by mass: 60-100 percent of high molecular weight polyethylene powder, 0-35 percent of aluminum oxide ceramic powder and 0-10 percent of a pore forming material. The method for preparing the composite membrane filtration pipe comprises the following preparation steps: (1) weighing the high molecular weight polyethylene powder according to the formula ratio, or weighing the aluminum oxide ceramic powder and pore forming material, filling the mixture into a mold, and pressing and compacting; (2) putting the mold into a constant temperature heating furnace, and heating according to a set heating curve; and (3) taking out the mold, naturally cooling, thereby obtaining the composite membrane filtration pipe. The composite membrane filtration pipe is high in strength, high in porosity and stable in filtration performance, and the filtering capacity can be restored by virtue of back flushing. Therefore, the service life of the composite membrane filtration pipe is greatly prolonged.

Description

technical field [0001] The invention belongs to the technical field of filter materials, and specifically refers to a composite membrane filter tube and a preparation method thereof. Background technique [0002] At present, in the industrial water treatment process, disposable filter materials such as quartz sand and activated carbon are generally used to filter out suspended solids in water, but the filtration performance of disposable filter materials will gradually weaken over time until they fail, and cannot be reused. The service life is short, in order to ensure a better filtering effect, it is generally necessary to replace it before the performance drops to 50%, resulting in waste. Contents of the invention [0003] The first technical problem to be solved by the present invention is to provide a composite membrane filter tube with high strength and good porosity, so that the filter performance is stable and the service life is long. [0004] In order to solve th...
