The reactor R3601A of GCT Company is a reinforced concrete tank in which the chemical reaction that produces phosphoric acid takes place. <\/p>\n\n\n\n
The reactor is protected by an anti-acid coating in butyl rubber with carbon brick. <\/p>\n\n\n\n
After years of service, the anti-acid coating inside the attack tank loses all or most of its capacity and the concrete will then be attacked by acid. <\/p>\n\n\n\n
The intervention of T.H.I REVETEMENT Company<\/strong> consists firstly in removing the old anti-acid rubber and carbon brick coating, secondly in stripping the contaminated layer of concrete to a depth of at least 10 cm. <\/p>\n\n\n\n After the stripping and cleaning work, the steel reinforcement of the old concrete is sandblasted and protected with a layer of anti-corrosion paint. <\/p>\n\n\n\n The next step is the reinforcement of the walls of the reactor with a new rebar reinforcement. <\/p>\n\n\n\n Following this, the stripped concrete layer is regenerated by the projection of a new layer of micro concrete at high pressure on the new reinforcement. <\/p>\n\n\n\n Once the new micro concrete layer is projected and leveled, the anti-acid protective coating system is applied, composed as follows: <\/p>\n\n\n\n – Application of a leveling and signaling coating in special anti-acid resin. <\/p>\n\n\n\n – Application of a 4 mm thick anti-acid butyl rubber sealing coating. <\/p>\n\n\n\n – Control of porosity and defects possible on the anti-acid coating by electric holiday detector. <\/p>\n\n\n\n – Application of a coating in one layer of anti- acid carbon brick for the wall and two layers of anti- acid carbon brick on the bottom.<\/p>\n","protected":false},"excerpt":{"rendered":" Cuve d\u2019attaque<\/p>\n","protected":false},"featured_media":17317,"template":"","nproject-category":[112],"nproject-tag":[87,85,86,89,104,88,94],"class_list":["post-17266","nproject","type-nproject","status-publish","has-post-thumbnail","hentry","nproject-category-chemical-industry","nproject-tag-beton","nproject-tag-brique","nproject-tag-caoutchouc","nproject-tag-carbone","nproject-tag-inox","nproject-tag-revetement","nproject-tag-revetement-interne"],"acf":[],"yoast_head":"\n
