The present invention is polypropylene nucleator and its preparation process with alkyl metal phosphate as material. The nucleator is prepared with organic phosphate and its derivative, superfine inorganic oxide, aluminium-lithium compound and high level aliphatic salt as material. The organic phosphate includes alkyl methylene di(2,4-bialkyl phenoxy) phosphate and di[alkyl methylene di(2,4-bialkyl phenoxy)] phosphate. The preparation process includes mixing, grinding and sieving and obtains polypropylene nucleator to 0.5-100 micron diameter.

The invention discloses a hexavalent chromium adsorbent and a preparation method and application thereof, and belongs to the technical field of environmental protection. According to the hexavalent chromium adsorbent and the preparation method and application thereof, edible fungus waste matrix-fungus chaff serves as the material, the advantages that the fungus chaff is loose and porous, large in specific surface area and rich in active group are utilized, and the fungus chaff is modified and prepared into an anion adsorbent and used for adsorbing hexavalent chromium which exists in an anionic form in electroplating wastewater. The fungus chaff modified adsorbent is used for treating hexavalent chromium wastewater, and on the condition that the pH is 5.5, the initial concentration of hexavalent chromium is 100 mg / L, the dosage of the adsorbent is 3 g / L, the adsorption time is 120 min, the temperature is 25 DEG C, and the rotating speed is 150 r / min, the adsorption quantity can reach 31.5 mg / g. The hexavalent chromium adsorbent and the preparation method and application thereof have the main advantages that agricultural solid waste resource recovery is achieved, contamination of waste fungus chaff to environment is reduced, the fungus chaff is applied to water pollution treatment simultaneously, resource utilization of agricultural solid waste is achieved, and the hexavalent chromium adsorbent has the advantages of being wide in material resource, low in preparation cost, easy to operate, high in adsorption efficiency and the like and can be widely applied to treatment of industrial wastewater in electroplating, printing and dyeing, tanning, metallurgy and the like.

An outdoor thick type fireproof coating for steel structure relates to a fireproof coating. Provided are an aluminate cement-based thick type fireproof coating for steel structure with an inorganic mineral thermal insulation combination material as main material, and a manufacturing method of the fireproof coating. The fireproof coating consists of a binder, a modifier, an aggregate and an enhancement material. The manufacturing method comprises sieving and drying the aggregate; pulverizing and sieving sheet-like mica; cutting off and dispersing the enhancement material; and well stirring the raw and auxiliary materials composed of the binder, the modifier, the aggregate and the enhancement material. The ratio of the modifier to each component of the aggregate and the enhancement material can be adjusted to promote full hydration of the aluminate cement binder and formation of a zirconia-containing aluminum silicate fiber interconnection net-like structure, change component viscosity and improve integrity of the coating. At the same time, a large amount of light fireproof components with different particle sizes are adopted to compact the coating and reduce the coating density. In addition, the coating has high adhesiveness, water resistance and flexibility, is free from cracking, falloff, chalking and wetting, and has good adhesion.
