Abstract
The utility model relates to a kind of test glass measuring mural painting, stone cultural artifact protective material steam breathability, its architectural feature is the groove platform that in test glass cup, span rim of a cup place has, in order to hold and fixing mural painting or stone cultural artifact sample block, distilled water is had in cup, space sealing wax between cup inwall and test block seals, again circular aluminum superzapping lid is pressed on rubber sheet gasket, and with fastened by screw; Or the edge of cup upper oral part is covered with and dries rear material membrane, material membrane underlay rubber sheet gasket with 5% dilute emulsion process of pure-acrylic emulsion, then circular aluminum superzapping lid is pressed on pure-acrylic emulsion material membrane, and with fastened by screw.The utility model is novel in design, makes simple, is widely used, for the research of mural painting protective material, screening, evaluation and engineering practice provide data supporting.
Description
Technical field
The utility model relates to a kind of test glass measuring mural painting, stone cultural artifact protective material steam breathability.
Background technology
Mural painting, stone cultural artifact protective material are some natural or synthesized polymer materials, such as gelatin, polyvinyl alcohol (PVA) and acryl resin etc.Use this class material protection mural painting, stone cultural artifact; generally the aqueous solution or the aqueous emulsion that are mixed with low concentration; to drip, injection or the mode such as spraying, by surperficial closure or infiltrate into certain depth and formed and to be interrupted or the tunic of partial continuous reinforces mural painting and stone cultural artifact.But mural painting, between stone cultural artifact body and the environment residing for it, itself there is normal steam and salt exchange, namely there is a kind of naturally " breathings " to act on, which maintains mural painting, balance between stone cultural artifact and environment.If after protective material is got involved; comprise in protective material process aging in-service; because the permeability of protective material to steam is bad; then can affect this balance; and then the stress that produces of the salt activity causing the top layer of mural painting, stone cultural artifact (as coat of colo(u)r) to cause due to steam and ftracture, peel off and come off; the deterioration of acceleration historical relic, causes irreversible damage.Therefore, measuring the steam breathability of protective material, is evaluate one of its important indicator as mural painting, stone cultural artifact protective material quality.
Summary of the invention
Based on above-mentioned, the utility model object is to provide a kind of test glass measuring mural painting, stone cultural artifact protective material steam breathability simply, reliably and accurately.
The purpose of this utility model is realized by following measures:
A kind of test glass measuring mural painting, stone cultural artifact protective material steam breathability; the groove platform that in test glass cup, span rim of a cup place has; in order to hold and fixing mural painting or stone cultural artifact sample block; distilled water is had in cup; space sealing wax between cup inwall and test block seals, then is pressed in by circular aluminum superzapping lid
rubber sheet gasketon, and with fastened by screw.
The free film of pure-acrylic emulsion after the pure-acrylic emulsion dilute emulsion process of 5% being dried covers the upper oral part edge in cup, pure-acrylic emulsion free film underlay rubber sheet gasket, upper pad circular aluminum superzapping lid, and with fastened by screw, is finally compressed by circular aluminum superzapping lid.
Described test glass is the cup of the circular inner bladder measuring mural painting test block, or for measuring the cup of stone matter test block square inner container.
Advantage of the present utility model:
The utility model designs a kind of test glass, can measure the steam breathability of protective material to mural painting simulating test pieces.2. measure protective material to the permeability of stone cultural artifact simulating test pieces steam.3. measure the steam breathability of the free film of protection pure-acrylic emulsion (comprising other synthesis and natural macromolecular materials).The utility model is novel in design, makes simple, is widely used, for the research of mural painting, stone quality guarantee protective material, screening, evaluation and engineering practice provide data supporting.
Accompanying drawing explanation
Fig. 1 is sample cup for liquid structural representation of the present invention.
Embodiment
In order to the function of clear description test glass, the utility model divides the mensuration of the steam breathability of the mensuration of the steam breathability of mural painting simulating test pieces and the free film of pure-acrylic emulsion to be explained:
The mensuration of the steam breathability of 1 mural painting simulating test pieces
As shown in Figure 1; a kind of test glass measuring mural painting, stone cultural artifact protective material steam breathability; test glass 1 measures the aluminum cup that mural painting test block inner bag is circle; 50-100ml distilled water 8 is added in cup; in cup, span rim of a cup 11mm place has the groove platform 7 of 1mm, and groove platform 7 is equipped with mural painting test block 5, and the sealing wax 6 that 75% paraffin and 25% beeswax are made into of the space between cup inwall and test block seals; again circular aluminum superzapping lid 3 is pressed on rubber sheet gasket 2, and fastening with screw 4.
In process of the test, by the test glass 1 handled well and circular aluminum superzapping lid 3, together put 25 DEG C into, in RH40% climatic chamber, after balance half an hour, rapidly circular aluminum superzapping lid 3 is placed on test glass 1 and compresses, be then placed on electronic balance that range is 1200g, precision 1mg, weigh, and recording quality value.And then put back in climatic chamber by test glass 1, and take off circular aluminum superzapping lid 3.In predetermined time interval, repeat above operation, record each mass value, by the unit of account time, in mural painting test block unit volume, steam through quality, the permeability to steam when measuring mural painting test block 5.
The steam breathability of the free film of 2 pure-acrylic emulsion
The free film of pure-acrylic emulsion after the pure-acrylic emulsion dilute emulsion process of 5% is dried cover have 15mm wide in test glass 1 rim of a cup edge on, pure-acrylic emulsion material membrane underlay rubber sheet gasket 2, again circular aluminum superzapping lid 3 is pressed on pure-acrylic emulsion material membrane, and fastening with three screws 4.
Pure-acrylic emulsion free film steam breathability process of the test is identical with the mensuration of the steam breathability of mural painting test block.
Claims (2)
