The present invention relates to an artificial inductive flowering asexual breeding method of bulbil konjak. Said method includes the following steps: making the bulbil konjak bulb undergo the process of flowering induction, inhibiting germination of lateral bud on the bulb and making the root tip grown out on the bulb be perished, promoting differentiation of top bud of konjak bulb to form flower bud, after the bulb is transplanted, artificially inhibiting flowered leafing plant growth, making flower bract can be matured and seeded so as to obtain lots of seeds capable of reproducing konjak.

The invention relates to the field of electronic application coatings, in particular to high wear-resistant vacuum coating ultraviolet light curing coatings. The composition and content of the high wear-resistant vacuum coating UV-curable coating are: 10-30wt% of difunctional urethane acrylate, 10-40wt% of high-functional urethane acrylate, 5-20wt% of high-functional acrylate monomer, single Functional acrylate monomer 0-15wt%, acid adhesion promotion 1-10wt%, photoinitiator 1-6wt%, nano wear-resistant material 0-5wt%, additive 0.1-2wt%, solvent 10-50wt%. The invention is aimed at protecting the surface of vacuum coating workpieces of electronic products such as mobile phones, MP3s, and digital cameras, and has the characteristics of good surface effect, super wear resistance, high temperature and high humidity resistance, cold and heat cycle resistance, and excellent yellowing resistance, among which RCA has the highest wear resistance It can reach more than 1500 times, effectively improving the service life of electronic products. The invention effectively solves the adhesive force and wear resistance of the UV-cured vacuum coating paint, solves the matching problem of the primer and top paint of the UV-cured vacuum coating paint, and has wide versatility.

The invention discloses an outer wall inorganic coating for tropical island buildings. The outer wall inorganic coating basically comprises, by weight percentage, 5-20% of silicone acrylic emulsion, 20-80% of nano-silica dispersing liquid, 1-3% of coupling agent, 2-6% of black tin dioxide powder, 1-5% of film-forming auxiliary, 10-20% of inorganic filler and the balance of deionized water, wherein the weight percentage of the outer wall inorganic coating is 100%. The outer wall inorganic coating has the advantages that the main film-forming substance of the outer wall inorganic coating is the nano-silica dispersing liquid, and the outer wall inorganic coating has the high temperature resistance, high humidity resistance, salt mist resistance and ultraviolet aging resistance of common inorganic coating; meanwhile, the silicone acrylic emulsion is mixed with the nano-silica dispersing liquid to allow organic polymer to be evenly distributed in the gaps between inorganic coating layers, the shrinkage of a coating film is buffered when the coating film is subjected to alternated cooling and heating, the coating film has certain elasticity, the formed coating film has the features of inorganic and organic coating, and the defects of the inorganic and organic coating are overcome; the added black tin dioxide powder has good photocatalytic activity and can generate an oxidation effect under the effect of sunlight, and effects of sterilizing, self-cleaning and mildew preventing are achieved.

The invention discloses a polycarbonate composition, which comprises the following composition in parts by weight: a, 86-99.5 parts of polycarbonate; b, 0.2-0.7 parts of perfluorinated polyolefin; c, 0.3 The flame retardant of part-13.8 part; Wherein, the sum of the weight parts of a, b, c three kinds of components is 100 parts. The present invention can obviously Improve the hydrolysis stability, abrasion resistance and flame retardancy of the polycarbonate composition, especially suitable for the field of electronic appliances.

A display panel and a manufacturing method therefor are disclosed. The display panel includes a first substrate, a second substrate disposed opposite to the first substrate, and at least one of a first organic film layer disposed on the first substrate, and a second organic film layer disposed on the second substrate, where at least one of the first organic film layer or the second organic film layer is an polyimide doped with a dichromatic organic dye.

The invention discloses a cultivation method for high yield of leaf surface bulbs of bulbel knojak underground bulbs. The cultivation method comprises the following steps of processing underground bulbs and dwarfing plants after leave expansion. Concretely, bulbel knojak underground bulbs are immersed into 40 to 80ppm paclobutrazol solution for 8 to 12 hours; then the bulbel knojak underground bulbs are taken out and stored in environment with the temperature of 15 to 35 DEG C and the humidity no more than 45%; when the day and night temperature is between 15 to 35 DEG C, the bulbel knojak underground bulbels are planted; during the primary period of konjak leafbud sprouting, sunshade is avoided and sunlight is employed for natural dwarfing of the plants; and dwarfing delayer is sprayed after the leaves are fully expanded. Azole compounds are employed for high-efficient plant growth inhibitor to dwarf and strengthen konjak plants, so fast growth of the konjak terminal bug plants in sunshade environment can be delayed and controlled and synthesis of gibberellins in parent bulbels can be restrained; plant apical meristem growth can be delayed and cell elongation speed can be decelerated; plants can be dwarfed but leaf formation cannot be affected; and nutrients in the plants can be quickly accumulated in the leaf surface bulbs.

The invention discloses anti-static discharge high-brightness mirror ink which comprises the following components in parts by weight: 80-90 parts of high-transparency resin, 10-20 parts of polyester resin, 0.3-0.6 part of aluminum powder, 4-22 parts of a hardener, 2-6 parts of additives and 0-20 parts of a solvent The invention also discloses preparation and use methods of the mirror ink, wherein the use method comprises steps of primary printing, secondary printing and silver embossing. The mirror ink provided by the invention adopts a novel formula in which the content of aluminum powder is reduced and a layered printing process is innovated, so that the printed products have high brightness and ESD resisting function, have no failure even if a human body operates a screen with static electricity, and have strong adhesion, high temperature and humidity resistance, high leveling, ultrasonic cleaning resistance, rich color and other excellent properties after being suffered to specific drying conditions.
