摘要:
L'invention vise à fournir un enduit intérieur en pâte sous forme d'un système au moins bicomposant comprenant un composant A et un composant B, dans lequel le composant A comporte un liant organique et un liant minéral comprenant un ciment alumineux et/ou un ciment sulfo-alumineux calcique, un bloqueur de prise, des charges minérales, un additif rhéologique, un régulateur/accélérateur de prise,éventuellement une base, les concentrations du régulateur/accélérateur de prise et de la base dans A étant telles que le pH de la partie A est inférieur au seuil de prise de la partie A;et le composant B comporte une base présente dans la partie B à une concentration permettant d'atteindre une valeur de pH final supérieure ou égale au seuil de prise de la partie A. Le procédé d'application, ainsi que le dispositif de mélange/projection pour la mise en œuvre dudit procédé font également partie de l'invention.
摘要:
The present invention relates to a process for the preparation of dispersions of colloidal polymerized particles and to the colloidal polymerized particles obtained and/or obtainable by the process as well as to their use.
摘要:
The invention relates to a composition of cement-polymer composite mixture to a process of developing and implementing a process of composition and the composition uses cement-polymer composites for construction of road infrastructure. Composition and process for obtaining it, and the application process according to the invention lead to the development of roads with enhanced solutions from existing knowledge and benefits consisting of: lack of expansion joints, the tread color from white - gray - gray to black, the road roughness can be controlled in the casting phase, which is adapted to the degree of slope and the necessary adhesion, the composition does not disintegrate in the environment, produces no emissions of particulate, gas and other toxic substances are even organic, not fuel Composition applied on the roads is a real barrier in wooded areas of the alpine areas of fire risk (fire caused by lightning or negligence); price represents 60% of estimated requirements for the construction of a section with recipes traditional asphalt or concrete road with lifetime of the building at 5 to 10 to 40 years depending on weather conditions.
摘要:
Jointing cement intending in particular for fastening together a plurality of filter blocks of a filtering body of an exhaust gas particulate filter of an internal combustion engine of a motor vehicle, having a silicon carbide (SiC) content of between 30 and 90%. The cement according to the invention includes at least 0.05% but less than 5% of a thermosetting resin, the percentages being percentages by weight relative to the total weight of the mineral material, apart from the possible water and the thermosetting resin.
摘要:
A composition for sealing hydrocarbon wells, wherein the composition comprises a prepolymer; a free radical initiator; a hydraulic material; a monomer and water, wherein the composition further comprises a radical inhibitor. A method and a use of the composition is also described.
摘要:
Systems and methods for modifying rheology of a cement slurry are described. Systems and methods may include a composition including at least one of: one or more polycarboxylate ethers (PCEs); one or more functionalized polyacrylamide co-polymers; and one or more polysaccharide biopolymers (BP).
摘要:
The invention relates to a cement formulation with two liquid components. This alleviates the problems which result from dust generation where a powdered cement component is employed. Furthermore, the cement may be formed with conventional liquid handling and mixing equipment. The cement binder formulation comprises a plasticizer. As the plasticizer is non-volatile, it remains an integral part of both the formulation and the final product obtained after application and drying of that formulation.
