The invention relates to silver paste for mobile phone shielding and a preparation method of the silver paste for the mobile phone shielding. The conductive silver paste comprises the following components, by weight, 45%-54% of metal silver powder, 7%-9% of high polymer resin, 0.2%-0.4% of adhesive force accelerant, 0.5%-2.0% of thickener, and 37%-45% of solvent. The production and preparation of the silver paste is completed through carrier preparation, silver paste preparation and production. Compared with the prior art, the preparation method can enable silver paste products to be solidified at 80 DECG in 30 minutes, and a resistance value after solidification is less than 1 ohm, and therefore not only are temperature-resistance requirements of shielding materials satisfied, but also resistance requirements needed by shielding are satisfied.

The invention relates to a construction method of a grass-shrub mixed ecological hard vegetation module, which comprises the steps of preparing a sticky casting body by reinforcing powder, fine sand and water, casting a hard module reserved with a notch for planting the grass-shrub plantation by the sticky casting body, hardening and molding three days later, planting the selected shrub cutting or bagged seedlings with vigorous growth at the notch, and diffusing the grass stems with germination ability or broadcast sowing the grass seeds on the module and covering a layer of fine sand to formthe ecological hard plant module with mixed grass and shrub twenty days later. The invention replaces the cement without clearance penetrating function with the reinforcing powder capable of forming penetration clearance, the 30MPa strength can satisfy the general resistance requirement, and can be used for hybrid planting grass and shrub. The grass-shrub roots and stems or bagged seedlings are selected for hybrid planting and for three-dimensional afforastation, and the vegetation module is combined with the hard module faster, thereby realizing a self-balanced ecological community, constructing a grass-shrub mixed ecological hard vegetation module and establishing a simple and three-dimensional landscape with rapid formation and stable sustainability.

The invention discloses an array substrate of a liquid crystal display device, and a signal wire and a manufacturing method thereof. The signal wire comprises a first part and a second part, wherein the second part is positioned on two sides of the first part; the second part is not higher than the first part; and at least one groove is formed in the second part. The invention also discloses an array substrate with the signal wire and a manufacturing method of the signal wire. The signal wire with a convex cross section is formed by forming a groove on the signal wire; and when a friction roller passes on the signal wire, the friction can be uniform, thereby solving the problem of unfavorable friction caused by excessive height of the signal wire.

The invention relates to the use of Real Michael Addition (RMA) crosslinkable composition for the preparation of a floor coating, to special RMA crosslinkable compositions with long working time and very short service time and low VOC and to specific floor compositions, in particular for use in high build floor coating applications.

The invention provides a tower lightning protection and grounding device, including a conductive connecting rod (3) and a grounding electrode (5) which are vertically arranged. The upper portion of the conductive connecting rod (3) can be electrically connected with a leg of the tower (1). The grounding electrode (5) comprises a coiled segment (51) and a connecting segment (52). The coiled segment (51) can be disposed in a sleeving manner outside a tower base (2) below the ground (4). The coiled segment (51) is electrically connected with the lower portion of the conductive connecting rod (3) through the connecting segment (52). According to the invention, the lower portion of grounding electrode is buried to a similar depth to that of the bottom of the tower base and laid in a plane manner surrounding the bottom of the tower base, so as to avoid secondary excavation in a laying phase, reduce the work amount and construction cost, and improve the tower grounding construction efficiency.

The invention provides a method of manufacturing scale-like grains on the surface of an aluminum-magnesium alloy with laser and belongs to the field of aluminum-magnesium alloy processing. The methodprovided by the invention comprises the following steps of adjusting a focal point: adjusting a conducting position to the focal point of a laser or a focal depth range of a field lens; drawing a vector diagram: drawing the vector diagram for the conducting position and copying and pasting the vector diagram to form a first diagram layer and a second diagram layer; laser bottom scanning: filling the first diagram layer of the vector diagram of a contour and scanning the same by the laser to form a compact alloy layer on the surface of the aluminum-magnesium alloy; and carrying out laser carving of the scale-like grains: filling the second diagram layer of the vector diagram of the contour, and generating the scale-like grains on a basic face of the original compact alloy layer by the laser. The method provided by the invention has the beneficial effects that the production efficiency is improved, a processed product is stable in performance, the conductivity is improved, and the product yield is improved; detection instruments such as a special multimeter and a magneto-ohmmeter are not used to detect, the step of quality detection is simplified, and detection can be performed directly through appearance, so that the production efficiency is improved greatly.
