The invention discloses a plant cultivation bowl and a production method thereof. The plant cultivation bowl comprises a cultivation bowl body, which is a column with one end and the other end closed, and the inner diameter of the closed end is smaller than that of the open end; a movably connected isolating layer is arranged close to the closed end to form a chamber with the closed end; nutrient solution mixed with compound microorganisms is filled inside the chamber; the isolating layer is provided with a plurality of through holes; the cultivation bowl body is formed by pressing bentonite, cattle chip, straw, bean pulp, humic acid and starch; the outer layer of the upper portion of the isolating layer is coated with hydrogel; hydrogel on the outer layer of the cultivation bowl body is coated with degradable plastics. The invention also provides a production method of the plant cultivation bowl. The plant cultivation bowl is degradable and can provide nutrition for plants planted inside the bowl, has the advantages of being high in water resistance and water retaining property and can improve the disease resistance of the plants. The plant cultivation bowl is particularly applicable to improvement of saline-alkali lands in dry regions or saline-alkali regions.

The invention discloses a fireproof door core. The fireproof door core is prepared from, by weight, 7-12 parts of light calcined magnesia, 20-35 parts of expanded perlite, 15-23 parts of bentonite, 13-21 parts of desulphurization gypsum, 4-8 parts of chopped fiber, 1-2 parts of foaming agent, 11-16 parts of fly ash, 4-8 parts of lignin, 0.5-1 part of expansible graphite, 0.2-0.4 part of zinc borate, 2-7 parts of modifier and an appropriate amount of water. The fireproof door core has the advantages of being excellent in fireproof performance, good in heat preservation performance, environmentally friendly and small in volume, and not generating toxic and harmful gas under fire.

The invention discloses a refractory ceramic tile. The refractory ceramic tile comprises the following raw materials in parts by weight: 10-20 parts of modified asbestos powder, 15-25 parts of corundum sand, 7-13 parts of dolomite, 14-21 parts of perlite, 10-18 parts of modified quartz powder, 20-30 parts of bentonite, 15-25 parts of montmorillonite powder, 3-6 parts of mullite fibers, 4-9 parts of magnesium oxide, 2-4 parts of zirconium dioxide, 3-6 parts of nano aluminum hydroxide and 4-7 parts of a binding agent. According to the invention, the proportion among the raw materials are controlled, so that the prepared product is uniform in structure, good in mechanical property, excellent in thermal shock resistance and good in erosion resistance.

The invention relates to powder coating. The power coating is characterized by being prepared from, by weight, 60-80 parts of magnesium carbonate, 4-5 parts of mica powder, 2-5 parts of cellulose, 3-5 parts of fluorescent powder, 4-5 parts of calcium hydroxide, 5-10 parts of bentonite, 2-10 parts of rubber powder, 60-80 parts of polyester resin, 20-25 parts of a curing agent, 35-40 parts of filler, 8-12 parts of a flatting agent, 4-6 parts of benzoin and 2-4 parts of a brightener. The powder coating has advantages of high hardness, scrubbing resistance, freeness of shedding, low cost and the like, and wall surfaces coated with the powder coating are bright and smooth as porcelain. Powder coatings formed by high-temperature baking and curing of the powder coating are remarkable in whitening resistance, and base material protection performance and appearance effects of the powder coatings are maintained.
