The present invention relates to a dry mortar panel (1) having at least one dry mortar layer (3), wherein the dry mortar layer (3) has a dry mortar mixture that is solidified by means of a water-soluble adhesive, wherein the dry mortar mixture consists of a mineral, in particular hydraulic binder, aggregate and where necessary at least one additive and/or at least one admixture, and wherein the dry mortar mixture has 5 to 35% by weight, preferably 10 to 25% by weight lightweight aggregate comprising open-pored and/or closed-pored lightweight aggregate grains (14) in relation to the dry mass of the dry mortar mixture, and to a method and a device for producing the dry mortar panel (1).
摘要:
The present invention relates to a new formaldehyde-free binder composition for mineral wool products, wherein the binder composition is an aqueous composition containing starch, wherein an amount of 95 weight % or more of the starch is water-insoluble native starch, and an acrylic component. The present invention also relates to the use of this formaldehyde-free binder composition in the manufacturing of mineral wool insulation products. Finally, the present invention relates to a process for manufacturing the formaldehyde-free binder composition wherein a dispersion of starch, wherein an amount of 95 weight % or more of the starch is water-insoluble native starch, is brought in contact with the acrylic component at a temperature of not higher than 40 °C.

A building product comprises calcium sulphate dihydrate particles bound by an organic binder. The calcium sulphate dihydrate particles each have a longest dimension and a lateral dimension, wherein the lateral dimension corresponds to the maximum breadth of the particle about the axis defined by the longest dimension. The calcium sulphate dihydrate particles havea low aspect ratio such that for at least 75% of the calcium sulphate dihydrate particles, the value of the lateral dimension is at least 20% of the value of the longest dimension.
摘要:
An extrudate comprising titania, a carboxyalkyl cellulose, and a hydroxyalkyl cellulose is disclosed. The extrudates have a smooth outer surface when they exit the extruder. The extrusion processibility is improved.
摘要:
The invention relates to a coated granulate for coating roads that comprises i) a mineral granulate and ii) a non-bituminous binder obtained from raw materials of vegetable origin. The binder comprises a cellulose compound of the cellulose fatty-ester family. The melting temperature of the cellulose compound is advantageously 60°C to 250°C, preferably 120°C to 180°C. The coated granulate may include 1% to 20% of the binder in weight percent relative to the material, preferably 4% to 10%. The invention also relates to a method for preparing a coated granulate using said binder.
摘要:
An acoustical plaster system features a base layer mixture and a finish layer mixture. The base layer mixture includes a first binder, a first thickener and a plurality of first particles, with the first particles being porous, lightweight, non-close packing particles having a first mean diameter. The finish layer mixture includes a powder latex binder, a second thickener and a plurality of second particles, with the second particles being porous, lightweight particles having a second diameter. The first mean diameter is larger than said second mean diameter.
