Time to teach you vacuum insulation common sense
1, vacuum insulation technology is a vessel insulation technology, it is the use of vacuum equipment to draw the air between the inner and outer walls of the vessel, so that the formation of a relative vacuum thermal insulation chamber. Heat preservation effect of vacuum ware is mainly affected by two factors:
The vacuum effect of the vessel: the higher the degree of vacuum, the better the effect of heat preservation.
The overall shape of the instrument: the instrument is bigger (more heat source contains more and more small vessels) and export (cross-sectional area for heat conduction is small), the sealing position farther away from the vessel mouth (heat conduction path is provided to the longer, the better insulation).
2, stainless steel vacuum ware, generally can be divided into: tubular vacuum (with a tail vacuum), the overall pumping gas (no tail vacuum) two kinds of different process technology products. (with two kinds of vacuum pan crosscutting map, map with the following two text)
No tail vacuum (integral seal): international advanced equipment, melting seal without leakage, high vacuum degree, long time of heat preservation, effective capacity and long service life.
Tail vacuum (tube type pressure seal): the equipment is simple, low cost, easy to be discouraged, the vacuum degree is low, the heat preservation time is short, the effective capacity is small, the service life is short.
3, a tail vacuum is a traditional process technology, such technical advantages are simple equipment, low production costs; shortcomings are easy to discourage, resulting in vacuum failure.
4, the vacuum process technology is one of the most advanced vessels, under vacuum conditions, the process controlled by the computer to complete the pumping and cooling and sealing. The Time Inc adopts the stainless steel vacuum ware produced by this technology, which has the following characteristics:
The high vacuum degree, long holding time: because it is vacuum pumping and sealing in nearly 1000 DEG C, the vacuum and vacuum the same, when the product is returned to normal temperature, the vacuum degree than "vacuum" is much higher, so the "times" brand vacuum pan / pot the insulation effect was higher than that of GB/T29606-2013 stainless steel vacuum cup "national standard".
Effective capacity: because there is no "tail vacuum" the same mouse tail, do not need to set a "hide tail room", so the effective space. With the "tail vacuum" of the same size of the conditions of the times, the effective space inside the product is much larger.
Long service life: "pressure sealing technology" there are hidden dangers. The sealing technology in high temperature melting the solder sealing airtight, so can not guarantee gas leak, effectively prolong the service life of the product.
