The invention discloses foaming equipment, which is used for foaming a preassembled component with a defined foaming space. The foaming equipment comprises a foaming mold, a first exhaust mechanism, a second exhaust mechanism, a first negative pressure supplying device, a sealing shell, an external exhaust mechanism and a second negative pressure supplying device, wherein the foaming mold is provided with a defined mold cavity; the first exhaust mechanism is communicated with the mold cavity; the second exhaust mechanism is arranged in the foaming space in an extending manner and is communicated with the mold cavity; the first negative pressure supplying device is connected with the first exhaust mechanism; the sealing shell is sheathed outside the foaming mold and the first negative pressure supplying device; the external exhaust mechanism and the second negative pressure supplying device are connected. According to the foaming equipment disclosed by the embodiment of the invention, negative pressure of air can be transferred into the foaming space by the second exhaust mechanism evenly, so that an insulating layer obtained after foaming has better insulating performance, the foaming materials can be saved, and the cost is reduced. In addition, due to the arrangement of the sealing shell, the foaming quality is guaranteed. The invention further discloses a foaming process employing the foaming equipment and a foaming process of refrigerating equipment.

The invention discloses a freezer and an inner container assembly for the same. The inner container assembly comprises an inner container and an opening frame, a ribbed ring which extends along the horizontal direction is arranged at the outer peripheral edge of the inner container, a first slot matched with the ribbed ring is arranged at the inner peripheral edge of the opening frame, a second slot which extends along the vertical direction and is adjacent to the outer peripheral edge of the opening frame is arranged on the lower surface of the opening frame, and the ribbed ring of the inner container is fittingly arranged in the first slot of the opening frame. According to the inner container assembly in an embodiment of the invention, the first slot and the second slot can be respectively matched with the inner container and a shell, and the position of the inner container is limited in the vertical direction, so that production and assembly of the freezer are facilitated. In addition, the inner container is prevented from falling off, a foam layer of the freezer has a preset thickness, the rejection rate of the freezer is reduced, the freezer is attractive, the foaming quality of the freezer is guaranteed, the freezer is simple in structure, assembly efficiency is improved, and cost is lowered.

The invention relates to foaming agent of waterproof foam concrete, a preparation method and a construction method, which belongs to the fields of construction materials, a preparation method thereof and an architectural method thereof. The foaming agent of the invention comprises the following raw materials in part by weight: 30 to 35 parts of keratinous albumen powder, 4 to 5 parts of Ca(OH)2, 1.5 to 2.5 parts of NaHSO3, 270 to 320 parts of water, 0.8 to 1.5 parts of sodium dodecyl benzene sulfonate (SDBS), 0.2 to 0.7 part of sodium dodecyl sulfate, 0.8 to 1 part of gelatin and 0.5 to 1 part of trolamine. The weight of sulphamic acid is matched with that of Ca(OH)2 and NaHSO3, and the pH value of the mixed three materials reaches 7.
