The invention provides a polypropylene thin film and a preparation method thereof. The thin film comprises a polypropylene core layer and a smooth surface layer adhered to at least one side surface of the polypropylene core layer. The smooth surface layer is a polypropylene layer with dispersed self-lubricating micro-particles. Fusion index of the polypropylene in the polypropylene core layer and the smooth surface layer under 230 DEG C and 2.16Kg are higher than 5g/10min and lower than or equal to 20g/10min. The self-lubricating micro-particles are high-molecular micro-particles with melting temperature higher than or equal to 250 DEG C and with both static friction coefficient and dynamic friction coefficient smaller than or equal to 0.6. The polypropylene thin film provided by the invention has excellent smooth performance, optical performance, and mechanical performance.

Provided is an ash melting temperature estimation device capable of quickly estimating the melting temperature of ash generated by combustion of a plurality of types of fuel. The device is provided with: a theoretical ash composition calculation unit which is provided with a mixing ratio acquisition unit for acquiring the mixing ratio of a plurality of types of fuel included in a target fuel, a fuel-corresponding ash composition acquisition unit that acquires a plurality of fuel-corresponding ash compositions comprising ash compositions of each of a plurality of types of fuel included in the target fuel, and a calculation unit that calculates a theoretical ash composition, which is an ash composition relating to a specific ash content of ash when the plurality of types of fuel are mixed atthe mixing ratio, on the basis of the mixing ratio and the plurality of types of fuel-corresponding ash compositions; an estimation model creation unit that creates an estimation model in which a relationship between a reference ash composition and a reference melting temperature for reference ash generated by combustion of the reference fuel is learned; and a melting temperature calculation unitthat uses the estimation model to calculate an estimated value of the melting temperature of the ash of the target fuel corresponding to the theoretical ash composition.

The invention relates to low-silver high-strength lead-free tin-based brazing filler metal and a preparation method thereof. The low-silver high-strength lead-free tin-based brazing filler metal is prepared from, by mass, 0.3%-1.0% of silver, 0.5%-0.9% of copper, 0.03%-0.5% of cobalt, 0.1%-1.0% of aluminum oxide, 0-0.05% of microelements and the balance tin. The preparation method of the low-silver high-strength lead-free tin-based brazing filler metal comprises the following steps that silver, tin and copper are smelted into smelting liquid; if cobalt exists in the components, tin and cobalt are added into the smelting solution; if cerium and/or phosphorus exist in the components, adding the copper-cerium alloy and/or the copper-phosphorus alloy wrapped by the tin foil into the molten smelting solution; after all the elements are melted, aluminum oxide powder is added, and smelting is conducted for 2-3 hours at the temperature of 500-600 DEG C; and injection molding. The method is convenient to smelt, low in loss, good in wettability, appropriate in melting temperature, small in welding spot, high in strength, good in reliability and resistant to high temperature.
