The invention relates to a magnetic-induction charged ceramic ultra-filtration membrane and a preparation method of the magnetic-induction charged ceramic ultra-filtration membrane. A metal fiber is added into a colloid particle solution and stirred up and dispersed, a dispersant, a thickening agent and a defoamer are added into the mixture solution to prepare a membrane formation solution, a porous support is coated with the membrane formation solution, the membrane is cast and cooled under the protection of nitrogen, so as to prepare the magnetic-induction charged ceramic ultra-filtration membrane. The retaining effect of the ultra-filtration membrane on charged ions varies with the external magnetic field, and the retaining effect can be adjusted at any moment according to the actual situation, and the retaining effect of the charged ions is larger than 98%. The ultra-filtration membrane has advantages of resistance to pollution and corrosion, high strength, long service life, and wide application value.

The invention provides a continuous injection shoe sole material and a processing method thereof. The continuous injection shoe sole material is prepared by mechanical mixing of a hard material and a soft material. The hard material is prepared by the melt extrusion and the granulation of oil filled rubber, polystyrene, K resin, polyphenylene ether, maleic anhydride modified propylene-based elastomer, and / or heavy calcium powder. The soft material is prepared by the mixing smelting and the granulation of oil filled rubber, methyl vinyl silicone rubber, C5 petroleum resin, foaming agent AC and expandable microsphere foaming agent. The oil filled rubber is prepared by mixing styrene-butadiene- styrene triblock copolymer and softening oil. The invention further provides a continuous injection shoe and processing method thereof. The prepared continuous injection shoe sole material has the following advantages that shoe surface and shoe sole can be formed by direct injection, and the continuous injection shoe sole material has the advantages of being light in weight, wear resistant, cold resistant, good in processing performance, and high in production efficiency, recyclable and environmental friendly and the like.

The invention relates to a low-temperature heat pipe filling method. The method includes the steps of heat pipe vacuuming, heat pipe filling, filling medium replacing, filled heat pipe cold welding, heat pipe section local heating, heat pipe exhausting, heat pipe leakage detection and heat pipe soldering and sealing. According to a low-temperature heat pipe filling process, through the technical schemes of filling medium replacing, vacuuming, heat pipe section local heating and exhausting, the problem of purity of room temperature filling of the low-saturated vapor pressure low-temperature heat pipe working media is solved. The process method is simple in equipment requirement, safe, reliable, convenient to operate and excellent in effect; by means of the filling process, the non-condensate gas amount in the filled low-temperature heat pipe is reduced, the constant temperature performance of the low-temperature heat pipe is improved, the heat transfer capacity of the low-temperature heat pipe is enhanced, the process method is low in implementation difficulty, and the low-temperature heat pipe filling method has engineering application and popularization value and significance.
