Container seal strip

Container seals The requirements of container seals are relatively strict, such as common shipping boxes, the basic time is at sea, there is strong ultraviolet sunshine, erosion by the sea, and drifting at sea, boxes and shaking extrusion of the container door seal requirements are also common basic requirements. There is an energy saving box, energy storage box, the sealing strip of this kind of box basically needs a large package Angle, with a wider size of the rubber strip, the properties of this kind of rubber strip mainly deal with the ultraviolet sunshine of the sun, with the requirements of the temperature as the focus, to prevent the backpouring of rain, and then flame retardant, fire prevention and smoke prevention, the grade number of sand prevention needs to be improved to prevent the erosion of internal equipment by wind sand. Such as energy-saving energy storage box compared with equipment boxes, mainly placed special operation equipment, the temperature and humidity in the box has certain requirements, such as freezer similar, freezer is mainly insulation will have a gap with the shipping box railway box, the insulation effect is higher, generally used, the inner door seal and the outer door seal are used together, with better insulation is more conducive to cold storage characteristics. Then there is the tank container, the international standard tank is a stainless steel pressure vessel installed in a tight external frame. The inner tank is mostly made of 316 stainless steel. Most tanks have steam or electric heating devices, inert gas protection devices, pressure relief devices and other optional equipment required for fluid transport and handling. Containers used to carry liquid cargoes such as wine, oil, liquid food, chemicals, etc. It is mainly composed of liquid tanks and frames. The liquid tank is elliptical or nearly spherical and adopts a double-layer structure. The inner wall adopts stainless steel; Or made of other rigid materials, but need to be coated with a layer of epoxy resin to pre Prevents corrosion of liquid cargo. The outer wall is made of insulation material. Generally, the top of the tank has a circular loading port, and the bottom of the tank has a discharge valve. There are high pressure liquid tank, low pressure liquid tank, heat preservation liquid tank, liquid tank with heating device and so on. The frame is made of high-strength steel, and the liquid tank is placed in the middle of the frame. The handling operation, loading, unloading and storage of tank containers need some special places. There are many kinds of sealing requirements for the filling box, and there are various technical indicators, which are generally determined by referring to the transportation products, and some need oil resistance, high elasticity, chemical stability, insulation, wear resistance, and processability air tightness, which are several categories for customers to choose.
