Electromagnetically-induced cement concrete crack self-healing diisocyanate microcapsules include raw materials, in parts by weight, comprising 15-55 parts of petroleum resin, 5-10 parts of paraffin, 5-10 parts of polyethylene wax, 3-10 parts of magnetic iron powder and 20-67 parts of diisocyanate. The diisocyanate microcapsules use the diisocyanate as a core material, and the petroleum resin/paraffin/polyethylene wax/magnetic iron powder mixture as the shell of the capsule. When micro cracks occur in the concrete, the crack propagation can break partial of the microcapsule inside, the diisocyanate inside the microcapsules flows out and diffuses into the crack and is subjected to a solidifying reaction with water in the concrete, so that the crack is repaired in time; and for the microcapsules that are not broken by cracks, external electromagnetic field can be applied to melt the shell to release the diisocyanate inside, thereby diffusing into cracks and solidify with water to repair them.

Mineral wool insulation products are provided. The mineral wool insulation includes a plurality of mineral wool fibers and a wax emulsion applied to the mineral wool fibers. The wax emulsion imparts excellent water resistance and thermal performance properties to the mineral wool insulation.

Described herein are methods of preparing cutin-derived monomers, oligomers, or combinations thereof from cutin-containing plant matter. The methods can include heating the cutin-derived plant matter in a solvent at elevated temperature and pressure. In some preferred embodiments, the methods can be carried out without the use of additional acidic or basic species.

The invention relates to a method for producing particles with pore structures, by means of a hybrid process of atomization via drying-cooling, from a water-in-oil-type emulsion of a composition of a non-solubilized and in melt state matrix. The production method comprises: i) forming a water-in-oil-type emulsion consisting of a composition of a solvent that is aqueous or soluble in water (dispersed phase) and a composition of a non-solubilized and in melt state matrix (continuous phase); ii) forming discrete particles from the emulsion via atomization, using a flow of gas at high pressure and temperature; iii) immediately removing the solvent via evaporation; and iv) subsequently cooling the formed discrete particles, resulting in porous particles that are substantially free from solvents.

Resin particles include a binder resin in each of the resin particles. The binder resin includes a biomass-derived resin, and polyethylene terephthalate or polybutylene terephthalate. An amount A of a biomass-derived component of the biomass-derived resin and an amount B of the polyethylene terephthalate or the polybutylene terephthalate satisfy A>B. Each of the resin particles has a core-shell structure including a shell layer and a core layer. An average thickness of the shell layer is from 100 nm to 500 nm.

A pigment dispersoid and a method for manufacturing the pigment dispersoid are provided. The method for manufacturing the pigment dispersoid includes the following steps. A pigment powder, a dispersant, and a plasticizer are mixed to form a dispersing solution. The dispersing solution is homogenized to form a pigment slurry. A carrier polymer powder is added into the pigment slurry to form a liquid mixture. The liquid mixture is stirred at a temperature ranging from 80° C. to 100° C. to form the pigment dispersoid. The plasticizer prompts the plasticization of the carrier polymer powder such that the pigment slurry is adsorbed by the carrier polymer powder during the plasticization to form the pigment dispersoid.

High jetness carbon black compositions using carriers to improve dispersion and maintain good masstone and undertone properties.

The invention relates to a bicycle frame made by injection molding pellets of a long glass fibre reinforced polypropylene composition having a core containing glass fibres and an impregnating agent and a sheath of polypropylene surrounding said core, wherein the pellets have an average length of at least 1 mm, the amount of the glass fibers is 10 to 70 wt % with respect to the composition and the polypropylene has a flexural modulus determined according to ASTM D790A of at least 1000 N/mm.sup.2.

A cellulosic particle contains cellulose as its base constituent. If hydrophobized silica particles are attached to the cellulosic particle, the percentage detachment upon sonication of the silica particles is 50% or less.
