Abstract
The douche that a kind of anti-biological film sticks is made up of base layer, transition zone and gel layer；Pass through UV-curing technology, under the effect of cross-linking agent and initiator, by amphion gel layer together with transition zone crosslinking curing at douche water passage surface, douche water passage surface is made to possess the anti-biological function sticked, can effectively reduce the douche in drip irrigation technique because microorganism is adhered at the wall of runner limit and forms biomembrane, solid suspended particle at flow path boundary due to relatively low speed, under biomembranous adhesion, particle builds up, and reduces runner valid circulation area and the situation of block water irrigator.
Description
Technical field
The present invention relates to drip irrigation technique field, be specifically related to douche that a kind of anti-biological film sticks and preparation method thereof.
Background technology
Douche as the critical component of drip irrigation system, the quality of its performance directly reflect the whole drip irrigation system life-span,
Water saving ability and uniformity of pouring water.The Main Bottleneck of the blockage problem of runner always suppression drip irrigation technique development, and along with regeneration
Developing rapidly of the technology such as water droplet filling, brackish water drip irrigation, rainwater drip irrigation, it is also proposed higher to the anti-blockage capability of drip irrigation system
Requirement, blockage problem has become the focus that drip irrigation technique is studied.Current result of study both domestic and external shows, overwhelming majority water dropper
Blocking composition is the inorganic particle that biomembrane sticks, after microbial film is formed, and the gelatinous agglomerate formed with fine grained, once
Enrichment will be difficult to peel off at short notice.Under sewage irrigation, drip emitter blocking material is mainly particle diameter > 0.06mm suspension
Granule (physical clogging), but particle is not the startup factor causing blocking process, and the accumulative of granule is as runner table
Biomembrane and the formation of flora mucus on face and start, for labyrinth runner, impurity particle is easily at microbial growth environment
Best sawtooth root concentrates deposition.Along with increasing of correlational study, the startup that emitter clogging is occurred by increasing scholar
The microorganism that factor is attributed in current forms biomembranous adhesion at runner limit wall.
Amphoteric ion polymer has hydrophilic anions and canons group, it is possible to higher by the hydration of electrostatic induction
Bound Water Molecules face, ground forms hydrophilic interface, at molecular level, it was demonstrated that the hydrone of surface adsorbed close is to confer to material and resists
The main cause of bio-adhesive properties, this discovery makes design antibiont adhesion characteristics material be possibly realized.
