Abstract

The invention discloses a production process of a low temperature phase change cold accumulation ice box or ice bag in the field of phase change material cold accumulation containers. The production process is implemented according to six steps including box or bag manufacturing, edge cutting or trimming, internal material stirring, filling, sealing and encasement. Purified water, ammonium chloride, sodium chloride, sodium carboxymethyl cellulose and antibacterial agents are slowly added into a reaction kettle in sequence; then, internal materials are stirred sufficiently, wherein the accurate ratio of the internal materials is 78.9 to 15.5 to 2.5 to 3 to 0.1; the stirred internal materials are poured in the ice box or ice bag, sealed and encased. The production process has the advantages of being good in cold accumulation effect, wide in usage, good in shaping performance (smoothness), suitable for low temperature refrigeration and freshness preservation, environmentally friendly and safe, lowering use cost, saving energy and power, shortening cold accumulation time, reducing cold accumulation space and the like.

Description

The production technology of low temperature phase change cold storage ice chest or ice bag

Technical field

The production technology of the cold accumulation container that the ultralow temperature phase-change material that the present invention relates to a kind of high-efficiency polymerization is content, more particularly, the present invention relates to a kind of low temperature phase change cold storage ice chest or ice

The production technology of bag.

Background technology

There is no at present and take cold-storage ice chest or the ice bag that the ultralow temperature phase-change material is content, common ice chest or ice bag content all be take super absorbent resin or thickener as main, can't reach real cold accumulation effects, after cold-storage, low temperature is held time short, generally subzero 14, spend to cold-storage in the refrigerator of 18 degrees below zero after 48 hours, initial temperature can only reach subzero 13 degree left and right, in the environment of 28 degree, the time that release temperature experiences to 0 degree is that about 30 minutes to 90 minutes, cold accumulation effects is poor.

Summary of the invention

The objective of the invention is to overcome the deficiencies in the prior art, provide that a kind of cold accumulation effects is good, constancy (planarization) is good, be more suitable for deepfreeze and fresh-keeping, reduce use cost, energy-saving

Electricity and the low temperature phase change cold storage ice chest of Environmental Safety or the production technology of ice bag.

The objective of the invention is to be achieved through the following technical solutions:

The production technology of a kind of low temperature phase change cold storage ice chest or ice bag, this technique by box processed or bag, cut or six steps such as deburring, interior material are stirred, filling, sealing and vanning are implemented:

The first step: bag, with the mould of pre-designed ice bag shape, be arranged on High-frequency machine or heat sealing machine, upper and lower two layers of plastic cloth or plastic composite cloth are welded together, form the sack that surrounds dress, reserved perfusing hole; Box processed, be arranged on blow moulding machine or plastics machine and carry out blowing or injection moulding with the mould of pre-designed ice chest shape, makes the ice chest that surrounds dress, reserved perfusing hole;

Second step: cut limit, for ice bag, along the mould indentation edge, cut sack; For ice chest, along the mould indentation edge, repair because of the inappropriate burr caused of material flowability, mould structure defect and moulding process;

The 3rd step: interior material stirs, pure water that will be good by the standard proportional proportioning, ammonium chloride, sodium chloride, sodium carboxymethylcellulose and antiseptic slowly add successively in reactor, the accurate ratio of pure water, ammonium chloride, sodium chloride, sodium carboxymethylcellulose, antiseptic is 78.9: 15.5: 2.5: 3: 0.1, then internally material fully stirred;

The 4th step: filling, by the product weight requirement, the interior material be stirred is poured in bag or box;

The 5th step: sealing, for ice bag with High-frequency machine or heat sealing machine by the sack sealing; Bottle cap firmly is welded on the ice chest perfusing hole with ultra-sonic welding machine for ice chest, makes it reach the effect of sealing;

The 6th step: vanning, on request by ice bag or box-packedly enter packing case.

Purpose of the present invention can also be achieved through the following technical solutions:

The proportioning allowable error of described pure water, ammonium chloride, sodium chloride, sodium carboxymethylcellulose, antiseptic is in ± 50%.The enough magnesium chlorides of described ammonium chloride energy, potassium chloride, calcium chloride, aluminium chloride, iron chloride, barium chloride, copper chloride, hydrogen chloride substitute.The material of described ice bag is plastics, comprise compound plastics, as aluminium foil, PVC, OPP, PE, TPU, EVA, nylon reach the compound Nylon Taffeta cloth of Compound Fabric outer bag, PVC, the compound cotton of TPU, PE composite terylene cloth, PE clad aluminum foil and compound paper bag as base material.The material of described ice chest is plastics or metal or composite, as PE, PP, ABS, nylon, iron, copper, aluminium, steel, alloy, bamboo and wood and fibrous composite.

Compared with prior art, the present invention has following beneficial effect:

1. there is obvious cold accumulation effects, cold accumulation effects after the polymerization of employing low temperature phase change cold storage material is 3 to 9 times of common ice bag, more than initial temperature can reach subzero 23 degree, in the environment of 28 degree, the time that release temperature experiences to 0 degree is about 4 hours 30 minutes;

2. purposes is wider: can be used as seafood, food, biological reagent, biological medicine, logistics transportation, freezer insulation etc.;

3. constancy (planarization) is good;

4. be more suitable for cryogenic freezing and fresh-keeping, reduce use cost;

5. energy saving, do not need special low temperature to carry out cold-storage as medium, reduces cool-storage time and cold-storage space;

6. Environmental Safety.
