Abstract

The utility model relates to a cultural relics decompression infiltration reinforcing apparatus. Decompression to cultural relics in a vacuum chamber is adopted, and protective agent liquid is not put in the vacuum chamber in advance, but is slowly injected in the vacuum chamber through a pipeline after vacuum is pumped for a period of time; then, when the pressure in the vacuum chamber is greater than external pressure, the protective agent liquid in the vacuum chamber is returned to a liquid storage pot. The utility model is firstly vacuum, and then the protective agent liquid is injected into the utility model to attain the purposes of decompression and permeation, making harmful substances of water, steam, etc. in pores on the surface of the cultural relics thoroughly exhausted out of the surface of the cultural relics; then, the protective agent liquid is slowly injected into the utility model, and the protective agent liquid thoroughly enters the deep positions of cultural relic bodies, making the cultural relics reinforced. The utility model solves the problems that the harmful substances in the protective agent liquid can not thoroughly eliminated by an isopiestic permeation method, the protective agent liquid does not deep enter the cultural relics, pollution and waste can be produced when the protective agent liquid is processed. The utility model has the advantages of simple structure, practicality, low cost, workload lightening, low cost of a reinforcing apparatus and easy operation.

Description

Cultural relics through decompression penetration reinforcement instrument

Technical field

The present invention relates to a kind of penetration reinforcement device, particularly a kind for the treatment of apparatus that historical relic is carried out the decompress osmosis reinforcing.

Background technology

There is 5,000 years magnificent historical civilized China to stay these historical historical relics of countless records, traces to the descendant.With the passing of the years, many cultural artifact surfaces begin weathering, oxidation, loose, become very fragile, fracture easily at a touch, damage, influenced the exhibition of these historical relics, the elegance that makes people be difficult to witness these historical relics is experienced shaking of Chinese time-honoured, has also influenced observation and the research of archaeology professional to these historical relics.

Before the present utility model, people adopt following ways and means usually to the protection of historical relic: the one, and brushing is reinforced, promptly brush at cultural artifact surface with front three resin, B-72 resin, 502 glue, organosilicon acrylic resin, acrylic resin, fluororesin etc., owing to be manually-operated, work under bad environment, taste is unpleasant, and is harmful, can't be brushed to historical relic the inside or recess, reinforce just inhomogeneous; The 2nd, normal pressure dipping penetration reinforcement is reinforced cultural artifact surface, and reinforcement depth is shallow; The 3rd, fragile historical relic is reinforced in synchronous vacuum impregnation; protective agent all is better than the first two kind to the even level of coverage of cultural artifact surface and the degree of depth; but still do not put the axe in the helve; though i.e. some macroscopical water; vapour is excluded out cultural artifact surface; but still fail fully to get rid of the adsorbed macroscopical water of historical relic surfaces externally and internally; harmful substances such as vapour; because the surface tension and the liquid level pressure of liquid; make the interior water of microcosmic pore of historical relic; vapour can't be got rid of; in case and cultural artifact surface covers for protected dose; then these harmful substances can't exclude all the better; continue to stay historical relic body internal corrosion historical relic; moreover the synchronous vacuum-impregnated degree of depth is still limited, can't satisfy the requirement to extreme fragile historical relic's protection.

Summary of the invention

The purpose of this utility model just is to overcome above-mentioned defective, and design, development is a kind of historical relic is carried out decompress osmosis adds protectant bracing means or equipment.

The technical solution of the utility model is:

Cultural relics through decompression penetration reinforcement instrument has vacuum chamber and vavuum pump, and its major technique is characterised in that the fluid reservoir connecting pipe, and the pipeline other end is connected vacuum chamber, takes out to return the liquid switch and connect vavuum pump, vacuum chamber, pipeline, fluid reservoir respectively by magnetic valve.

Advantage of the present utility model and effect are to utilize and earlier historical relic are vacuumized; water in the pore through making cultural artifact surface after a while then; harmful substances such as vapour by micro-crack and capillary under the effect of little difference force of saturated vapor pressure gradually; slowly and fully discharged cultural artifact surface equably; slowly inject protective agent liquid under the situation of pressure reduction again existing; be that protective agent enters the historical relic depths more fully under differential pressure action; this will firmly get many than the degree of depth that synchronous vacuum infusion techniques enters; make the historical relic deep inside obtain reinforcing; this is that the reinforcing historical relic is most important, also is the most difficult.

Taking out in the utility model returned the liquid switch and at first made in the vacuum chamber and vacuumize, treat that the vacuum in the vacuum chamber reaches when setting value, keep a period of time, make harmful substances such as water in the pore of cultural artifact surface, vapour under the effect of little difference force of saturated vapor pressure, fully be discharged cultural artifact surface gradually, lentamente by micro-crack and capillary; To take out again and return the liquid switch and be allocated to the fluid injection station; slowly to inject protective agent liquid under the situation of pressure reduction again be material reinforced dose of fluorine existing; make protective agent under differential pressure action, enter historical relic body depths more fully; this degree of depth than synchronous vacuum infusion techniques infiltration will be firmly got many; make the historical relic deep inside obtain reinforcing; this is that the reinforcing historical relic is most important, also is the most difficult.

After to be protected dose of liquid slowly is injected into and finishes in the vacuum chamber; to take out the switch that returns in the liquid switch again is allocated to and returns the liquid station; make the pressure in the vacuum chamber be higher than fluid reservoir; remaining protective agent liquid is discharged from vacuum chamber by pipeline in the vacuum chamber thereby make; to the tank body jar, stopped protectant waste, reduced workload; solve pollution problem, made operation very simple, convenient.The utility model structure is but very simple, and cost is also low.
