Description
Technical field
The present invention relates to Dust Improvement field, specially a kind of dust suppression type anion powder, PET intermingling materials and preparation side
Method.
Background technology
Since reform and opening-up, as industrialization and modernization development, the air pollution problems inherent that China faces are more and more tighter
Weight, especially haze problem, have seriously affected daily life.One big direct sources of air pollution are exactly scattered miscellaneous
Airborne dust caused by material outdoor accumulating processing, such as the outdoor accumulating processing of sandstone cement for building, building waste it is outdoor
Accumulating, reprocessing, the outdoor accumulating in thermal power plant, the coal cinder of steel mill, coal dust is processed and the large area of crops is outdoor
Ted, preliminary working etc., especially northern China enter after winter occur it is dry, green vegetation is rare and continuously blows
Phenomenon, the significantly generation of airborne dust has been further exacerbated by it.
For caused dust pollution problem in the above-mentioned scattered outdoor accumulating process of debris material, at present, more and more
The relative closure or totally-enclosed property factory building that mining area or harbour are made using new material, not only cost is low, intensity is high, and installs
It is also very convenient with safeguarding.
New material is mostly the PET materials of environmental sound used by current making air film structure or dust-suppression net structure workshop
Material.PET, i.e. polyethylene terephthalate, are commonly called as polyester resin, and it is the condensation polymer of terephthalic acid (TPA) and ethylene glycol, with
PBT is referred to as thermoplastic polyester, or saturated polyester together.Nineteen forty-six, Britain delivered first patent for preparing PET, 1949
ICI companies of Britain complete pilot scale, but after du pont company's purchase patent, nineteen fifty-three establishes process units, in the world at first
Realize industrialized production.Initial stage, PET was nearly all used for synthetic fibers (China is commonly called as terylene, dacron).The 1980s with
Come, PET has breakthrough development as engineering plastics, develops nucleator and crystallization promoter in succession, at present PET and PBT mono-
Rise and be used as thermoplastic polyester, turn into one of five large-engineering plastics.PET points are cut for fiber polyester chip and non-fiber level polyester
Piece.1. fiber-grade polyester is used to manufacture terylene short fiber peacekeeping polyester filament, polyster fibre enterprise processing fiber and correlation are supplied with
The raw material of product.The terylene kind maximum as yield in chemical fibre.2. non-fiber level polyester also has the purposes such as bottle class, film, extensively
It is general to be applied to the fields such as packing business, electronic apparatus, health care, building, automobile, wherein packaging is the maximum non-fine application of polyester
Market, while be also the fastest-rising fields of PET.As packaging material PET advantages:1. there is good mechanical property, impact is strong
Degree is 3~5 times of other films, and folding resistance is good.2. oil resistant, resistance to fatty, resistance to olefin(e) acid, diluted alkaline, resistance to most of solvents.3. with excellent
Good high- and low-temperature resistance performance, can be long-term use of in 120 DEG C of temperature ranges, and short-period used is resistant to 150 DEG C of high temperature, is resistant to -70 DEG C
Low temperature, and very little is influenceed on its mechanical performance during high and low temperature.4. gas and vapor permeability are low, existing excellent choke,
Water, oil and peculiar smell performance.5. transparency is high, ultraviolet can be stopped, glossiness is good.6. nontoxic, tasteless, wholesomeness is good, can
It is directly used in packaging for foodstuff.
However, although PET material has many advantages, such as, but it is used to make air film structure or dust-suppression net structure workshop is dissipated
The dust suppression of debris material, also it is only the diffusion for preventing from dissipating debris material airborne dust in accumulating process to greatest extent, and does not have
Active depositing dust dust suppression function, particularly with dust-suppression net made of conventional PET material during dust suppression, due to dust-suppression net in itself
Network, it is even more like water off a duck's back less than or equal to 10 microns of particulate matter to aerodynamic diameter.It is and such trickle
Particulate matter can float for a long time in an atmosphere, form suspension floating dust, and superfine particulate matter can be not only directly sucked in by people and damage, and
And pollutant can also be taken to far place, cause pollution range to expand.Research finds that the harmfulness of ultrafine dust is much larger than
It can be seen that the harmfulness of dust, ultrafine dust has higher adsorptivity, can adsorb the materials such as VOC in air, forms aerosol,
So as the reaction " container " of a variety of chemical reactions, and then photochemical fog is formed, injure eye irritation mucous membrane, cardinal symptom
Have headache, respiratory disorder, chronic respiratory disease deterioration, Pulmonary Function in Children abnormal etc..
Anion is derived from the positively chargeds such as bacterium in anion and air, dust, smog to the catharsis of air
Particle phase combines, and is polymerized to big dust particle and is settled.The Brownian movement that anion is done in atmosphere is to eliminate ultrafine dust
The effective ways of particulate matter, experiment proves that floating dust diameter is smaller, easier on the contrary to be caught by anion, after combining reduction activity
Precipitation.According to non-patent literature《Environment, health and negative oxygen ion》Show：Anion in air is to lung particulate matter
PM2.5 regulation effects are splendid.So the diameter of maximum is endangered in the air containing high concentration small particle anion, in PM2.5
Below 1um micronic dust, bacterium, virus etc. are almost nil.According to non-patent literature《Negative aeroion is in health care and environmental protection
Application》Show：Light ion (small particle anion) in air to as low as 0.01 μm, be industrially difficult to the particulate that removes
Floating dust, have and absolutely settle removal effect.
