Pressure, now material temperature can raise, cycle of higher pressure 10-15min, carries out foam production after survey rifle sample is qualified；Respectively to foaming before, foaming
Rear door body is weighed, and checks whether actual groundwater increment meets technological requirement, entity bubble average density 31.5-32kg/m3Meet technique
It is allowed for access after requirement and is just producing product, material temperature 18-22 DEG C, mold temperature 35-55 DEG C, steel plate door shell need to heat post-foaming,
During foaming, casing preheating drying tunnel temperature 35-55 DEG C；, tank body pressure 2-4bar, material feeding pressure 100-150bar are black, expect material feeding in vain
Pressure differential is less than 10bar, black and white material mass ratio 1.2-1.3:1；Sample is reactive: wire drawing time 50-60s, does not glue time 80-
90s, density 22.5-23kg/m3；Rifle head flow: straight line 1400-1500g/s, ground loop wire 900-1000g/s；Curing time
700s-900s；
(4) general assembly section: install temperature control, prepackage compressor adnexa on casing, install compressor, by fixing for temp. controlling box rear pre-
Dress refrigerating evaporator, prepackage refrigerating evaporator will be frozen vaporizer after completing and be welded and fixed, be pacified by middle hinge by door of refrigerator afterwards
Dress is fixing, is then installed by cold sotrage door fixing by upper hinge, tears blue adhesive tape, overlay film, cleaning refrigerator, then mounting knob seat,
Glass shelf, now carries out outward appearance and casing inspection, reprocesses immediately as undesirable, carry out power supply when installing compressor
Line is adaptive, dead earth line, power line afterwards, then installs compressor relay cover, carries out pipe arrangement afterwards, blows dirt, by low
Silver soldering connects, high silver soldering welding device for drying and filtering, carries out solder joint cleaning, pipeline shaping after having welded；Then take out
Vacuum, pull out snap joint, attaching water pond, carry out cooling medium charging sealing afterwards, finally by low pressure leak detection, safety check and high pressure inspection
Leakage；
(5) packaging section: the refrigerator after general assembly being completed carries out commodity inspection test, pastes circuit diagram, nameplate, bar code after completing,
Dress door handle lid, then installs fixing fruit and vegetable box, places description, adnexa, carries out end after pasting efficiency, essence copper pipe labeling afterwards
Examine, after inspection is qualified eventually, put door body protection foam, set inner bag, overlap carton, put protection angle brace, dividing plate, top cover, last joint sealing, packing
Machine is packed.
Solder joint mopping during described dress door handle lid, patch note labeling, then fix back cover, power line.
The valve charging refrigerant equipment is opened during described cooling medium charging, to refrigeration system adds 30-60g cold-producing medium,
Compressor is restarted after it circulates 1-5min in refrigeration systems.
Described low silver solder is silver solder, silver wire, silver soldering sheet, silver soldering ring, the one in silver soldering powder solder flux.
Described high silver solder preparation method be first by containing 5% Sn, the P of 5%, the Ni of 1%, the Ag of 2%, 87%
Cu at normal temperatures uniformly mixed preparing alloy raw material standby, then 1000～1200 DEG C, the vacuum less than 10Pa, vacuum
Induction melting in induction heater, it is cast into ingot；Then use hot extrusion molding method, at a temperature of 450～550 DEG C, will close
