Embodiment Construction

[0008] Introduce embodiments of the present invention below in conjunction with accompanying drawing:

[0009] refer to figure 1 , the embodiment of the packaging device of the present invention includes a bag 1 with at least one end having a feed opening, and is characterized in that: a bag holder is provided outside the middle part of the bag, and the bag holder is composed of a thin rod 2 placed inside the folded middle part of the bag and a sleeve It is formed by a hoop 3 on the outer edge of the folded middle part of the bag and has a seam on the bottom side.

[0010] During packaging, 35-45 parts by weight of ammonium bisulfate, 45-55 parts by weight of ammonium nitrate, 25-35 parts by weight of sodium sulfite, and 90-100 parts by weight of sodium sulfate added with water are weighed according to the weight ratio. First put sodium sulfate with water on the end of the bag that does not have a feed inlet, then clamp the folded middle of the bag with a card bag clip, then ...

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. technical background [0002] At present, ice packs made of chemical refrigerants are showing more and more broad application prospects in 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 patent 2 CO 3 ·7H...
