Ice crystal pad and ice bag making technology

In recent years, the market's hot “cool pad” has roughly two categories: one is a liquid cooler pad (including a cool cap). It uses water as a cooling material, and the natural evaporation of water makes people feel cool. It is commercially available for 6-10 yuan. The other type is an ice crystal pad, which is a product made by the present technology. The refrigeration material is a polymer material, and the current market price is 12-20 yuan. Its characteristics are: not only has a lower temperature than the freezing point, but also has a slow heating rate, but also has the characteristics of inhibiting the heat conduction function and keeping cold for a long time. It also has the function of solid water and does not produce water separation or moisture leakage when subjected to pressure or even thawing. , can be used repeatedly for a long time.

First, material preparation

1. Preparation of Cooling Material First, pour 98.7 parts of clean water into an oil-free heating pot or heating barrel. Add 1 part of lime-fat resin, 0.2 parts of sodium polyacrylate and 0.1 parts of ethylene diene, then heat up slowly and follow it. The stirring, generally when the temperature rises to about 80 degrees Celsius, the raw materials will be completely dissolved, and when it is confirmed that all the materials are dissolved and stirred uniformly, that is, the cease-fire allows them to naturally cool, and when the temperature is cold to room temperature, the cold-keeping material is frozen. Its cost is 0.24 yuan per kilogram.

2. PVC fabrics for coats are 1.5 meters wide and the market price is 7.50 yuan per meter, that is, 5 yuan per square meter. Other waterproof and wear-resistant fabrics may also be used.

3, the application of thick film within the inner film bag and strong tensile strength, drawing rate of 1.5-2 times the new material film.

4, heat sealing machine desktop, portable can be less than 100 yuan sold.

Second, product production Product specifications are usually: cushion 43X38 centimeters, pillow 53X33 centimeters, ice 25X12 centimeters, cushions are home sofa size, car seat size set.

1. Make a 43X 38 cm five-seat cushion and cut the fabric to a size of 80X 45 cm. The film was cut into five pieces of 43X18 cm, and the surface was folded into 9 cm with 18 cm. After the film was heat-combined into a bucket, 500 grams of frozen ice crystals were placed in each bag and sealed by heat sealing. Five pieces of ice crystals were then frozen and placed side by side. Into the jacket cloth, and finally the surrounding tight, and four of the five lines are also sewn tightly, put on the outer package Serve. The total production cost is 2.8 yuan, which is very good at the summer heat.

2. Make a 25X 12 cm anti-burning ice pack to cut the fabric into 27X 26 cm. Press 26 cm and fold it into 13 cm. The film can be made of a new, slightly thin film, which is slightly smaller than the outer bag. After the rectangular bag is hot-synthesized, 600 grams of ice crystals are frozen in the film, and the ice can be sealed in the outer cloth cover without the need for delivery. The total production cost is about 0.9 yuan, and it is sold at 5 yuan. Listed sales should also be packaged. For fever and cold burns excellent results, every family must.

Food Grade Poly-Y-Glutamic Acid is often used as a food additive and flavour enhancer in the form of its sodium salt, monosodium glutamate.

1. Poly Glutamic Acid has been implicated in epileptic seizures. Microinjection of glutamic acid into neurons produces spontaneous depolarisations around one apart, and this firing pattern is similar to what is known as in epileptic attacks.

2. Free glutamic acid is present in a wide variety of foods, including and and is responsible for one of the five basic tastes of the human sense of taste.

3. All meats, poultry, fish, eggs, dairy products, as well as are excellent sources of glutamic acid. Some protein-rich plant foods also serve as sources.

4. Auxigro is a plant growth preparation that contains 30% glutamic acid.

Function:

1.Food industry:

as thickener for foods & drinks, improves taste of drinks, stabilizer in ice creams, texture enhancer, binder, animal feed supplement, antifreezing agent or cryoprotectant, bitterness relieving agent, as an additive in preparation of starch foods (bakery & noodles) for avoiding staling, enhancing food texture and maintaining food shapes.

2.Health Care:

Facilitates calcium absorption in osteoporosis cases.

3.Medical treatment:

Drug release carrier, a haemostatic agent, soft tissue augmentation
