Abstract
Abstract: Within the framework of a European project, three cleaning laser devices are tested to evaluate the influence of different parameters on stone cleaning rate and efficiency. The project objective is to design a large surface-cleaning laser. One of the devices is a prototype with some technological improvements compared to the lasers used today for restoration. The tests are performed on limestone and sandstone covered with various dirt layers. The influence of fluence, water spraying, spot area, frequency, as well as particle emission rate is investigated. Results allow a comparison of the importance of each parameter and confirm the increase in cleaning speed of the new prototype. Nevertheless, it can be concluded that an automatic device will be suitable to attain a cleaning speed competitive with other traditional cleaning techniques.

Nevertheless, it can be concluded that an automatic device will be suitable to attain a cleaning speed competitive with other traditional cleaning techniques.</ce:simple-para></ce:abstract-sec></ce:abstract><ce:keywords class="keyword"><ce:section-title>Keywords</ce:section-title><ce:keyword><ce:text>laser cleaning</ce:text></ce:keyword><ce:keyword><ce:text>stone</ce:text></ce:keyword><ce:keyword><ce:text>cleaning rate</ce:text></ce:keyword><ce:keyword><ce:text>limestone</ce:text></ce:keyword><ce:keyword><ce:text>building</ce:text></ce:keyword></ce:keywords></head></converted-article></istex:document></istex:metadataXml><mods version="3.6"><titleInfo lang="en"><title>Assessment of laser cleaning rate on limestones and sandstones</title></titleInfo><titleInfo type="alternative" lang="en" contentType="CDATA"><title>Assessment of laser cleaning rate on limestones and sandstones</title></titleInfo><name type="personal"><namePart type="given">Martin</namePart><namePart type="family">Labouré</namePart><affiliation>Société Quélin, Rueil-Malmaison, France</affiliation><role><roleTerm type="text">author</roleTerm></role></name><name type="personal"><namePart type="given">Philippe</namePart><namePart type="family">Bromblet</namePart><affiliation>Laboratoire de recherche des monuments historiques, 29, rue de Paris, 77420 Champs-sur-Marne, France</affiliation><affiliation>Correspondence and reprints: philippe.bromblet@culture.fr</affiliation><role><roleTerm type="text">author</roleTerm></role></name><name type="personal"><namePart type="given">Geneviève</namePart><namePart type="family">Orial</namePart><affiliation>Laboratoire de recherche des monuments historiques, 29, rue de Paris, 77420 Champs-sur-Marne, France</affiliation><role><roleTerm type="text">author</roleTerm></role></name><name type="personal"><namePart type="given">Günter</namePart><namePart type="family">Wiedemann</namePart><affiliation>Fraunhofer Institut Werkstoff und Strahltechnik, Dresden, Germany</affiliation><role><roleTerm type="text">author</roleTerm></role></name><name type="personal"><namePart type="given">Christophe</namePart><namePart type="family">Simon-Boisson</namePart><affiliation>Thomson CSF Laser S.A., Guyancourt, France</affiliation><role><roleTerm type="text">author</roleTerm></role></name><typeOfResource>text</typeOfResource><genre type="research-article" displayLabel="Full-length article" authority="ISTEX" authorityURI="https://content-type.data.istex.fr" valueURI="https://content-type.data.istex.fr/ark:/67375/XTP-1JC4F85T-7">research-article</genre><originInfo><publisher>ELSEVIER</publisher><dateIssued encoding="w3cdtf">2000</dateIssued><copyrightDate encoding="w3cdtf">2000</copyrightDate></originInfo><language><languageTerm type="code" authority="iso639-2b">eng</languageTerm><languageTerm type="code" authority="rfc3066">en</languageTerm></language><abstract lang="en">Abstract: Within the framework of a European project, three cleaning laser devices are tested to evaluate the influence of different parameters on stone cleaning rate and efficiency. The project objective is to design a large surface-cleaning laser. One of the devices is a prototype with some technological improvements compared to the lasers used today for restoration. The tests are performed on limestone and sandstone covered with various dirt layers. The influence of fluence, water spraying, spot area, frequency, as well as particle emission rate is investigated. Results allow a comparison of the importance of each parameter and confirm the increase in cleaning speed of the new prototype. Nevertheless, it can be concluded that an automatic device will be suitable to attain a cleaning speed competitive with other traditional cleaning techniques.</abstract><note type="content">Figure 1: Cleaning rates obtained with different devices under different working conditions. w, wet; D, dry; F, frequency; S.M., Saint Michel de Bordeaux; N.D., Notre Dame de Paris.</note><note type="content">Figure 2: Colour variation (ΔE*) with two different machines (NL 101 and NL 201) under different working conditions (wet or dry surface, maximum frequency or half of the maximum frequency) on Notre Dame limestone.</note><note type="content">Figure 3: Emission rate during the cleaning of different stones versus cumulated fluence (n*J).</note><note type="content">Figure 4: Particle size distribution of emissions during the cleaning of different stones (measurements by means of a cascade impactor after Professor Berner).</note><note type="content">Figure 5: Number of pulses per spot area used to clean the stone under different working conditions and different fluences (NL 201 on Notre Dame limestone).</note><note type="content">Figure 6: Behaviours of NL 201 and R/2 versus spot area and fluence on the sandstone paving blocks of Champs-sur-Marne Castle.</note><note type="content">Table I: Characteristics of the three laser devices used.</note><note type="content">Table II: Fluence (J) and impact surface (s) of pulses in optimum working conditions.</note><subject lang="en"><genre>Keywords</genre><topic>laser cleaning</topic><topic>stone</topic><topic>cleaning rate</topic><topic>limestone</topic><topic>building</topic></subject><relatedItem type="host"><titleInfo><title>Journal of Cultural Heritage</title></titleInfo><titleInfo type="abbreviated"><title>CULHER</title></titleInfo><genre type="journal" authority="ISTEX" authorityURI="https://publication-type.data.istex.fr" valueURI="https://publication-type.data.istex.fr/ark:/67375/JMC-0GLKJH51-B">journal</genre><originInfo><publisher>ELSEVIER</publisher><dateIssued encoding="w3cdtf">20000801</dateIssued></originInfo><identifier type="ISSN">1296-2074</identifier><identifier type="PII">S1296-2074(00)X0003-9</identifier><part><date>20000801</date><detail type="volume"><number>1</number><caption>vol.</caption></detail><detail type="supplement"><number>S1</number><caption>Suppl.</caption></detail><extent unit="issue-pages"><start>S1</start><end>S356</end></extent><extent unit="pages"><start>S21</start><end>S27</end></extent></part></relatedItem><identifier type="istex">70DD69BA87D78194FCE62DD3CD0DBE5A642E3342</identifier><identifier type="ark">ark:/67375/6H6-X65NQG3N-H</identifier><identifier type="DOI">10.1016/S1296-2074(00)00195-3</identifier><identifier type="PII">S1296-2074(00)00195-3</identifier><accessCondition type="use and reproduction" contentType="copyright">©2000 Éditions scientifiques et médicales Elsevier SAS</accessCondition><recordInfo><recordContentSource authority="ISTEX" authorityURI="https://loaded-corpus.data.istex.fr" valueURI="https://loaded-corpus.data.istex.fr/ark:/67375/XBH-HKKZVM7B-M">elsevier</recordContentSource><recordOrigin>Éditions scientifiques et médicales Elsevier SAS, ©2000</recordOrigin></recordInfo></mods><json:item><extension>json</extension><original>false</original><mimetype>application/json</mimetype><uri>https://api.istex.fr/ark:/67375/6H6-X65NQG3N-H/record.json</uri></json:item></metadata><serie></serie></istex></record>Pour manipuler ce document sous Unix (Dilib)
