Description
Technical field
The present invention relates to refrigerator foaming field, specifically a kind of refrigerator decompression foaming case clamp.
Background technology
Refrigerator is as daily required household electrical appliance, and more and more universal comes into common people house, while people are for ice
The function and species of case it is also proposed higher requirement.Wherein refrigerator body as refrigerator chief component, for low temperature
Food is preserved, widely used polyurethane uses foam process as insulation material, the process of casing.
Polyurethane foam principle：Polyurethane foam is that polyalcohol and isocyanates course of reaction middle-molecular-weihydroxyethyl continue to increase,
Bubble is constantly produced in simultaneous reactions liquid phase, foam is formed.Continue to increase, bubble is constantly produced in simultaneous reactions liquid phase, formed
Foam.Foaming agent is to prepare the essential raw material of hard polyurethane foams, and it is typically the lower boiling liquid compound of a class.
The heat produced in foaming process vaporizes foaming agent, produces gas core and increases, bubble is wrapped to form by polyurethane reaction thing.
Because boiling point is directly proportional to air pressure.Air pressure is bigger, and boiling point is higher;Air pressure is lower, and boiling point is lower.For example, steam copper
Steam pressure in stove, the boiling point that there are about the water in tens atmospheric pressure, boiler can be more than 200 DEG C.And for example, in height above sea level 1900
At rice, atmospheric pressure is about 79800 handkerchiefs, and the boiling point of water is 93.5 DEG C.
Traditional handicraft is that casing carries out foam process in open environment, so can be caused by regional height above sea level difference
Air pressure difference, and cause the difference of foaming parameters.In addition also due to foaming process rapid gas generating, and can not be timely
Diffusion, forms the local pressure of foamed zones and is unfavorable for the formation of foam.
Decompression foaming is, casing an equipment controlled less than being foamed in normal pressure certain value.Foam environment
Air pressure it is relatively low when, foaming agent be easier from reaction liquid phase in escape, formed gas core.When air pressure is lower, gas karyogenesis it is faster,
Expanding foam solution expansion is rapider, and the mobility for showing as foam is higher, distributivity is better.When reacting quickly, gas core, which increases, to be exceedingly fast,
Abscess is minimum.Foam aperture and structure can so be greatly improved.So decompression foaming technology be at all to create one it is close
The space closed, and with vavuum pump produce a negative pressure environment, then casing foamed inside it.Foaming terminates, and opens this
Individual closed space, takes out product.
The country has also introduced this technology at present, and applied to production.But find in actual applications due to fixture repeatedly
Folding, though using soft seal, still this negative pressure confined space is difficult to control to.Because the system is a complete closed system
System, even if so when being closed in design in fixture, the trickle leakage of joint will also result in the pressure transient of inside.So that
The technology is disabled after introduction of production line, is used as normal pressure foaming, causes the waste of equipment.
