Embodiment Construction

[0008] A kind of refrigerant involved in the present invention is characterized in that: described refrigerant is made of ammonium bisulfate, ammonium nitrate, sodium sulfite and sodium sulfate decahydrate, i.e. Na 2 SO 4 10H 2 O is formulated, and its weight ratio is 35-45 parts by weight of ammonium bisulfate, 45-55 parts by weight of ammonium nitrate, 25-35 parts by weight of sodium sulfite, sodium sulfate decahydrate, namely Na 2 SO 4 10H 2 O, 90-100 parts by weight.

[0009] The preparation steps of the refrigerant are as follows: after weighing each component of the refrigerant according to the weight ratio, sodium sulfate is placed on one side of a portable packaging device provided with a separator, and ammonium bisulfate, sodium sulfite, nitric acid The ammonium is placed on the other side of the portable packaging device provided with a partition device, and the partition device of the packaging device is opened during use to allow the components of the refrigera...

Abstract

The inventions are sorts of magnesium, magnesium alloy which is compound plating coat of high anti corrosion, and their preparation technics. They belong to domain of surface treatment of non-ferrous metal. Compound plating coat based on the chemical nickel coat, the thickness of which is between 20 and 25 micron. The callow of it is electrolytic zinc plating and nickel alloy, the thickness of which is between 8 and 10 micron. The following is the preparation craftwork; the chemical nickel plating of magnesium alloy adopts the standard B480-88 of American material experimentation association. Plating time is between 1.4 and 2 hours. The coating thickness if between 20 and 25 micron. The content of phosphor in the plating layer is 9-12%; electrolytic zinc plating and nickel alloy: the plating liquid of it and technics conditions are followed: sodium hydroxide 8-15%, zinc oxice 2-5%, nickelous chloride 0.5-3%, ethylamine 2-4%; tiethanolamine 2-4%, nylander reagent 0.5-3%, DE0.2-0.8%, sodium dodecanesulphonate 0.01-0.1%, the overmeasure is water. Curl density is 0.5-5A / dm2. Plating time is 30 minutes.

Description

technical field [0001] The invention belongs to the technical field of refrigeration, and in particular relates to a formula of a chemical refrigerant and a packaging device thereof. Background technique [0002] At present, ice packs made of chemical refrigerants are showing more and more broad application prospects in occasions such as medical cold compresses, fresh-keeping, summer cooling and heatstroke prevention. Compared with ordinary ice packs, portable chemical refrigeration ice packs have the advantages of easy storage, transportation and long cooling time. Based on this, many researchers have developed it in recent years. For example, Chinese patents 95112233.9, 92216591.2, and 96229387.3 disclose several portable refrigeration devices, but there is little technical content about refrigerants. Propose the use of Na 2 CO 3 ·7H 2 O, NH 4 NO 3 and NH 4 Cl, according to the ratio of 1:1 ~ 3:1 to prepare a portable refrigerant. The raw material Na used in this p...
