Description
Technical field
The utility model is related to plastics corrosion experimental device fields, more particularly to a kind of plastics resistance to liquid energy scale
Experimental provision.
Background technology
With the fast development of petro chemical industry, oil deep process technology is increasingly perfect, and plastic products type is increasingly more
Sample, yield increase sharply.Plastic tube is small, corrosion-resistant with its density, resistance is small, easy to install, low cost, energy saving notable
Advantage obtains the extensive use of pipeline engineering circle.From the 1950s, plastic tube manufacturer of developed country and pipeline engineering
Boundary has carried out a large amount of cooperations, and plastic tube is promoted to account for critical role in pipeline engineering, material also with the trend of plastics steel not
Disconnected development.China develops and uses plastic tube since 20 world sixties, and the eighties, plastic tube started to transport in city gas
Middle application.Due to the implementation of China's Energy restructuring and clean energy resource policy and the continuous propulsion of Urbanization Construction, naturally
The usage amount of gas increases year by year, promotes the application amount of Plastic Gas pipeline constantly soaring.China's plastic conduit is produced as within 2014
13000000 tons, be 7.44% compared with industry overall growth in 2013, the occupation rate of market of plastic conduit is in all material pipeline
Ratio is 40~50% or so.In recent years, house town and country construction industry was always one of main application fields of plastic conduit,
Annual plastic pipe work dosage is about at 300~4,000,000 tons, and wherein municipal works pipeline accounts for about 2/3, and architectural engineering pipeline is about
1/3 is accounted for, accumulation usage amount of the plastic conduit in house town and country construction industry reaches 40,000,000 tons or so.Develop in " 13 "
In planning, plastic conduit is even more to be listed in the product widelyd popularize.Therefore plastic conduit has preferable development prospect in China.
In terms of plastics are widely used in pipeline transportation and corrosion-resistant container as a kind of corrosion-resistant new material, but plastics
And will not non-fully it corrode.The corrosion failure of one of dominant failure mode during metal material use is same in plastic applications
Sample exists, and in the collective effect of complex environment and conveying medium, plastic conduit and container also can be broken by the long-term corrosion of medium
It is bad to fail in turn.The etch state of plastics has a larger difference relative to metal material, and common etch state exists in metal
It there's almost no in nonmetallic materials.Therefore, the corrosion mechanism of plastics is also relatively easy.In material and environmental selection reasonable design
Under conditions of, the corrosion of plastics is broadly divided into physics corrosion and chemical attack two major classes.
Physics corrosion is plastic tube is made plastic components surface molecular loosen by the effect of medium molecule in the medium, principle
It is that gradual loosen of surface macromolecular that medium molecule is in direct contact leaves plastic components surface and enter medium, finally makes plastic section
Part surface loosens, thickness reduces, and from the superficial to the deep, the intensity of plastic components continuously decreases this process, until plastic components fails.
Physics corrosion process generally can be divided into two stages progress.First stage：Plastics are in the medium by medium temperature or pressure etc.
After the effect of factor, media fraction molecule, which becomes active, simultaneously " attacks " frosting macromolecular gap, makes the macromolecular chain of plastics
Section loosens, and the swelling of frosting is presented.Second stage:Under " attack " of medium molecule, the macromolecular of frosting is forced
" pulling down " enters medium, completes corrosion process.Physics corrosion not mechanically makes frosting macromolecular be detached from modeling in layer
Material itself enters medium, also related with the order degree of the molecule arranging structure of plastics, while being also possible to along with chemistry
The process of corrosion.
Chemical attack is under the action of medium molecule, and the macromolecular structure of plastics is destroyed or chemically reactive, is generated
Other substances enter medium and the physics of plastic products and chemical property and mechanical property are caused to change, such as intensity drop
The low, service life, which reduces, even fails, and chemical attack is mainly shown as weightless, discoloration, oxidation and decomposes.Chemical attack is most representative
Be substitution reaction, in plastic material molecular structure the effect of functional pendant groups receptor 1 activity medium occur oxidation, nitrification, chlorination,
The substitution reactions such as sulfonation cause material corrosion resistance to decline, and the mechanical property of material is deteriorated.In addition it is crosslinked between plastic molecules anti-
Material embrittlement, hardening should be also resulted in.
A kind of important failure mode of the corrosion failure as plastics, but the basic data of its correlative study is less, for modeling
The experimental method of the materials and parts immersion corrosion of resistance to different medium and experimental provision are incomplete.Plastics immersion corrosion experimental applications are more wide
General is the bioassay standard of GB/T 11547-2008 plastics-resistant to liquid chemical reagent performance.This standard impregnates plastic corrosion-resisting
The ruler of test solution type needed for experiment and dosage, soaking time and temperature, specimen types, experimental procedure and the front and back sample of experiment
Very little, quality and volume have made detailed regulation, and recommend the experimental provision of immersion corrosion experiment.

It is respectively at the both ends of capillary.In use, sample is put into one of the glass spherical container, in another glass marble container
It is put into medium solution；Experimental provision is placed vertically and is read this moment vertical；Medium solution enters dress when being inverted experimental provision
The glass spherical container for having sample, is impregnated；Experimental provision is erect again after after a time, records the quarter of medium solution
Degree variation.Although this experimental provision can accurately measure solution variation, there is also problems with：(1) each experimental provision is every
Secondary experiment can only place a sample, cannot meet the requirement of experiment of multiple parallel samples under same experiment condition；(2) cannot expire
The experiment of sufficient multicycle then needs a large amount of similar device, according to GB/T11547- to multicycle and more Duplicate Samples immersion tests
The requirement of 2008 standards, primary experiment need 7 experimental periods, and a cycle needs 5 Duplicate Samples, need 35 this experiment dresses
It sets, if to investigate the soak test of multiple material, plurality of liquid medium, leads to that entire pilot system is very huge, bad control
System and management；(3) corrosive medium is replaced to be more troublesome；(4) midway sampling process is cumbersome, and there are larger safety winds when sampling
Danger；(5) liquid to be tested is in static state, cannot reflect the erosion performance to material in dynamic process.
