The invention provides an evaporating device and aims to solve the problems that an evaporating device in the prior art needs to be provided with an independent conveying chamber, evaporating chambers need to be vacuumed again for evaporation every time, the evaporating device is complex in equipment and long in conveying and vacuuming time and the like. The provided evaporating device comprises a plurality of evaporating sub-chambers. The evaporating device has the advantages that evaporation in layers is completed by moving a to-be-evaporated base plate among the evaporating sub-chambers, so that conveying time of the to-be-evaporated base plate is saved; by maintaining the evaporating sub-chambers in a same vacuum environment, the evaporating sub-chambers need not to be vacuumed again, so that vacuuming time is saved.

A package for an electronic component includes a first substrate and a second substrate. In the package, an interior space capable of housing the electronic component is formed between the first substrate and the second substrate, a sealing hole communicating with the interior space and an exterior is formed in at least one of the first substrate and the second substrate, the interior space can be airtightly sealed by melting a solid sealant provided in the sealing hole, and an interior wall of the sealing hole has a curved surface extending in directions of penetration and inner periphery of the sealing hole.

The invention discloses a vacuuming method and a device thereof, which are used for vacuuming the interlayer between the outer cylinder and the inner cylinder of a multilayer heat-insulating container. Wherein the vacuum pumping device comprises: a first gas conveying device, which has a gas outlet; a first gas heater, whose inlet is connected with the gas outlet of the first gas conveying device, and whose outlet is connected with the air inlet of the inner cylinder pass; vacuum unit, which communicates with the interlayer; the second gas delivery device, which has a gas outlet; the second gas heater, whose inlet is connected with the gas outlet of the second gas delivery device, and whose outlet is connected with the interlayer connected. By adopting the vacuum pumping method and its device of the present invention, the vacuum pumping time of multi-layer thermal insulation storage tanks, tank containers, and tank trucks is shortened from 7-15 days to 3-6 days, which greatly shortens the time for high-vacuum multi-layer thermal insulation storage tanks. , tank container, tank car manufacturing cycle, reducing manufacturing costs.

The invention discloses an organic fiber toughened inorganic composite artificial stone panel and a preparation method thereof. The panel comprises a surface layer, an intermediate organic fiber toughened layer, and a base toughened layer, wherein the surface layer comprises the following raw material components in parts by weight: 40-70 parts of quartz sand, 10-30 parts of a quartz powder, 20-45parts of an inorganic active powder, 0.5-4 parts of a pigment, 0.3-1 part of a water reducing agent, and 3-10 parts of water; the intermediate organic fiber toughened layer comprises the following rawmaterial components in parts by weight: 40-60 parts of the inorganic active powder, 45-65 parts of sand, 0.8-1.5 parts of the water reducing agent, 6-14 parts of water, and 4-8 parts of organic fibers; and the base toughened layer comprises the following raw material components in parts by weight: 30-50 parts of the inorganic active powder, 30-55 parts of the quartz sand, 15-20 parts of the quartz powder, 0.5-1.2 parts of the water reducing agent, 4-8 parts of water, 0.8-2.5 parts of a toughening agent. The panel has good volume stability, low shrinkage, no warping and deformation during use,extremely low water absorption, good durability, no problems such as aging, good adhesion between layers, and good ductility and no instant brittle fracture, can be used as a bearing structure, has good surface dirt resistance, and is suitable for popularization and use.
