2results about How to "Reduce drying speed" patented technology

The utility model relates to the field of grain drying equipment, and discloses a drying device for grain storage, which comprises a box body, an outer cylinder is arranged in the box body, a baffle ring is fixedly connected in the left side of the outer cylinder, three upper flow plates are fixedly connected to the inner top wall of the outer cylinder, and four lower flow plates are fixedly connected to the inner bottom wall of the outer cylinder. And an inner cylinder is arranged in the outer cylinder. Through the arrangement of the outer barrel, the inner barrel and the feeding hopper, the problems that the storage stability of grains is reduced, the moisture content of the whole batch of grains is inconsistent, the drying time can be correspondingly prolonged, further heat exchange between hot air and the grains can be hindered to a certain extent, and the drying speed is reduced can be solved; therefore, the uniform heating effect is effectively improved, the consistency of the water content of the whole batch of grains is guaranteed, the drying quality is improved, the drying time is shortened, and the drying efficiency is improved.

This invention relates to the field of coating paste technology, specifically to a two-dimensional nano-Ti3C2T x Material-modified waterborne slurry, its preparation method, and its application. This waterborne slurry comprises the following components by weight percentage: 85.9–89.2% waterborne polyurethane resin, 3–5% two-dimensional nano-Ti3C2T. x The aqueous dispersion contains 0.3% acrylic thickener and 5-6% slow-drying solvent. The aqueous slurry contains Ti3C2T. x It does not affect the drying speed of the printing paste; the slow-drying solvent reduces the drying speed during printing, preventing screen clogging; after printing, Ti3C2T x Temperatures above 50℃ can accelerate the drying speed of the slurry coating and improve efficiency. Adding Ti3C2T... x Subsequently, due to its large specific surface area, the viscosity and thixotropy of the water-based slurry increase rapidly, which can avoid the problem of poor water washability of the coating caused by excessive addition of acrylic thickeners.
