摘要:
The present invention relates to a novel agent for promoting adhesion to a heat-insulating surface and in particular to a polystyrene surface, especially when wet or under the effect of a large variation in temperature. The invention also relates to the use of the said agent in a water-insoluble film-forming polymer composition or in a mineral binder composition for applications in the construction field and more particularly in external heat-insulation systems.
摘要:
The invention relates to a method for increasing the waterproofing of a mineral binder compound consisting in adding the sufficient quantity of at least one type of polyalkylalkylsiloxane containing at least one hydrocarbon graft which has 6-18 carbon atoms to said compound. Compounds which can be produced with the inventive method and the use thereof for construction are also disclosed.
摘要:
The invention relates a method for applying a finish coat, for example in the form of a paint or varnish on a surface based on a still humid mineral binder compound. Said invention relates, in particular to mineral binder compounds in the form of mould parts and prefabricated elements for construction, civil engineering or public works. It is possible to give an example of mould parts or prefabricated construction elements embodied in the form of cement or concrete tiles, said cement or concrete being reinforced or not by fibers, gypsum board liners, mould fiber cement elements or gypsum plasterboards.
摘要:
The present invention relates to a process for improving the physicochemical properties of bitumen compositions and also to novel bitumen compositions with improved properties and to their uses in a process for preparing hot bitumen mixes or in a process for preparing cold bitumen mixes.
摘要:
Novel carriers for liquid component antifoaming agents, e.g., polysiloxane based, and well adapted for detergency applications, are comprised of a preferably hydrated sodium tripolyphosphate fraction, and a fraction comprised of sodium hydrogen pyrophosphate, sodium hydrogen orthophosphate, or admixture thereof.
摘要:
Novel granular particulates of sodium metasilicate, well adapted for improved detergency applications, are comprised of a central core of essentially anhydrous sodium metasilicate and a core-enveloping sheath of sodium metasilicate pentahydrate therefor, the amount of water which comprises said sodium metasilicate pentahydrate comprising at least 10% by weight, and advantageously from 10 to 20 or 25% by weight, of the total weight of said particulates.
摘要:
The invention concerns a method for preparing thermoplastics to obtain a hydrophilic behaviour of the surface of objects made from said thermoplastics. The invention also concerns the additives used to obtain said surface hydrophily, said additives being mixed and jointly melted with the thermoplastics (mass-additivation process). The melted mixtures of thermoplastics and additives are shaped by any conventional means (extrusion, injection film stretching) to obtain the desired objects. The invention further concerns the uses of said thermoplastic objects with hydrophilized surfaces.
摘要:
The present invention relates especially to a composition for manufacturing an article comprising one or more superposed layers each less than 5 centimetres thick, comprising a hydraulic binder and at least one compound chosen from an organic compound comprising at least two hydrophilic functions and a hydrophobic chain, and a polyamide oligomer. The use of these additives in the presence of hydraulic binder allows the manufacture of articles and coatings with good protection against water uptake, satisfactory water resistance and good mechanical properties such as breaking strength.
摘要:
The invention concerns solid granulates of a system comprising at least a hydrophobic organic active substance (for example an active detergent substance) encapsulated in solid particles of an alkali-water soluble organic polymer derived by emulsion polymerisation, said particles being dispersed in and encapsulated by a matrix in a water soluble or water dispersible dry organic compound. The invention also concerns the use of said granulates in detergent compositions, in particular for cleaning hard surfaces or for washing clothes and the detergent compositions.
摘要:
Anhydrous sodium metasilicate is stabilized against attrition or "dusting" in detergent and other use, by formulating same with such amount of an additive, e.g., a hydrate, that will transfer water content to the anhydrous metasilicate, at a temperature less than the fusion temperature of sodium metasilicate pentahydrate and as will convert from about 1% to 20% by weight of said anhydrous metasilicate into its pentahydrate form.
