There is provided a pour point depressant for lubricants that has an effect of lowering pour points of both solvent refined base oils and high viscosity index base oils. A pour point depressant for lubricants comprising: a mixture of an alkyl (meth)acrylate polymer (A) that is composed of an alkyl(meth)acrylate containing alkyl groups having an average carbon number (CA) of 12.5 to 13.8, and an alkyl(meth)acrylate polymer (B) that is composed of an alkyl(meth)acrylate containing alkyl groups having an average carbon number (CB) of 13.9 to 15.5.

The invention provides a bottle arranging mechanism. The bottle arranging mechanism comprises a bottle arranging disc and a bottle separating barrier fixedly arranged on the bottle arranging disc, wherein the bottle arranging disc comprises a bottle arranging area for arranging bottle bodies, the bottle arranging area is provided with bottle arranging textures, and each bottle arranging texture comprises a texture section stretching from the middle part of the bottle arranging disc to the outside of the bottle arranging disc. The bottle arranging mechanism provided by the invention has the advantages that the resistance is reduced, and a bottle falling phenomenon is prevented from happening.

The invention discloses a method for manufacturing stem shreds by processing tobacco stems. The method includes the steps of stem and leaf separating, tobacco stem screening, tobacco stem warming and humidifying, stem pressing, stem roasting, tobacco stem storing, tobacco stem dampening, tobacco stem formula mixing, secondary tobacco stem warming and humidifying, second stem pressing, stem shred cutting, stem shred adding, stem shred warming and humidifying, stem shred drying, stem shred winnowing, perfuming and the like. A whole set of complete new stem shred processing method from leaf hitting tobacco stem re-roasting processing to stem shred manufacturing from the tobacco stems is formed. According to the method, the stem shred production environment is improved; the production cost is reduced; the stem shred quality is improved. The method is easy and convenient, and strong in maneuverability; and large-scale production and application can be conveniently achieved.

The invention relates to a fiber-reinforced cement composite concrete prefabricated building component (PC-FRC) and its production method, which is suitable for building exterior wall decoration, building structure enclosure, energy-saving and thermal insulation projects, and is especially suitable for prefabricated housing industrialization projects. It is suitable for people's livelihood fields such as natural disaster emergency response and post-disaster reconstruction. Including decorative surface layer, fiber-reinforced cement layer, concrete structure layer, insulation layer and steel skeleton; fiber-reinforced cement layer is compounded on the decorative surface layer, and fiber-reinforced cement layer is connected with concrete structure layer; insulation layer is laid in the concrete structure layer , the insulation layer is completely wrapped by the concrete structure layer; a steel skeleton is also laid in the concrete structure layer. Fiber-reinforced cement layer, thermal insulation layer and concrete structure layer are compositely molded in molds with shapes. There are exposed steel bars on the surface connection parts of the prefabricated building components, which are used for the connection between the prefabricated parts and the building structure during building assembly; the hoisting embedded parts are laid on the concrete structure layer.

The invention discloses an environment-friendly type chemical reagent containing device for chemical engineering.
