Abstract
The invention discloses a kind of degradable PLA water filtering elements, filter core material of main part is PLA fibers, the PLA fibers are extruded after PLLA, PDLA, PGLA and water purification agent blending at 160~200 DEG C by spinneret die, by rolling collector formation fibre web and being molded.The water purification agent is the one or more in nano zine oxide, Nano Silver, activated carbon.The filter core can play relatively effective antibacterial, bactericidal action while physical filtering is realized, meanwhile, after the filter element replacing of PLA materials, it can be realized in compost environment degradable.
Description
Technical field
The present invention relates to a kind of water purification catridge, specifically a kind of degradable PLA water filtering elements.
Background technology
In traditional water purification catridge material, the application of PP cotton filter cores is relatively broad, and it is original using acrylic resin
Fiber is made in material, and the winding through fiber itself is bonded and formed.With high porosity, high rejection, dirt of receiving greatly
The characteristics of amount, big flow, low pressure drop.Be widely used in pure water, solvent, coating, detergent, beverage,
Liquid filtering of the industries such as drinks etc..
The diligent consumptive material changed is needed because filter core belongs to, a large amount of use of PP materials causes influence on environmental problem,
Conventional bowl is only capable of realizing the function of physical filtering simultaneously, without water purification, fungistatic effect, there is certain office
It is sex-limited.
With being grown to even greater heights with the cry preserved the ecological environment as the green waves of core, the feature of environmental protection of material and
Security is by extensive concern.PLA is a kind of new biodegradation material, uses reproducible plant
The starch material that resource (such as corn) is extracted is made, can be complete by microorganism in nature after use
Degraded, ultimately generates carbon dioxide and water, free from environmental pollution, this is highly beneficial to environmental protection.
The content of the invention
Aiming at the existing problems and shortcomings of the prior art, the technical problems to be solved by the invention are to provide one kind
Degradable PLA water filtering elements, while physical filtering is realized, can play preferable water purification sterilization
Effect, while realizing the safe and environment-friendly, degradable of material.
In order to solve the above technical problems, the technical solution used in the present invention is：A kind of degradable PLA water purification
Filtration core, filter core material of main part is PLA fibers, wherein, the PLA fibers are made up of following components：With
Percentage by weight meter
A kind of above-mentioned degradable PLA water filtering elements, water purification agent is in Nano-Zinc, Nano Silver, activated carbon
It is one or more of.
Above-mentioned a kind of degradable PLA water filtering elements, by spinneret mould at 160~200 DEG C after each component mixing
Head extrusion, by rolling collector formation fibre web and being molded.
As explanation, in said components, PLLA (poly- PLLA) and PDLA (poly- dextrorotation PLA)
Stereocomplex body structure can be formed, the heat resisting temperature of PLA is greatly improved；PGLA and PLLA has very
Good compatibility, while PGLA can be effectively increased the toughness of filter core.
The invention has the advantages that and advantageous effects：
1st, a kind of degradable PLA water filtering elements of the present invention, can realize extraordinary physical filtering effect,
Certain antibacterial, bactericidal action can be played simultaneously.
2nd, a kind of degradable PLA water filtering elements of the present invention, with extraordinary heat resistance and mechanical strength,
Adapt to a variety of conditions.
3rd, a kind of degradable PLA water filtering elements of the present invention, PLA is as biological environmental production material, with non-
Often good Safety and Environmental Protection and degradability, can be degradable after being replaced and abandoning.
4th, the present invention is practical, and simple to operation, production cost is relatively low, is easy to marketing.
