| Akron abrasion | cm3/1.61km |
Table 3: the gel heat pad that embodiment makes compares with the performance difference between ordinary hot pad:
| Ordinary hot pad | Accumulation of heat heat pad | |
| Price | Lower | Higher |
| Weight | Lighter | Heavier |
| Energy-conservation | Nothing | Have |
| Portability | Nothing | Have, but heavier |
| Electricity fail safe | Better | Better |
| Radiativity | Lower | Nothing |
| Heat accumulation function | 5-15min | >4h |
| Application and derivative expansion | Generally | Better |
Heat accumulation function is more than 20 times of ordinary hot pad as can be seen from the above table, therefore, can save mass energy.
As: 1 liter of gasoline is 7 yuan, when consumption per hour amount of gasoline × idling is dynamic turn in sleep 5 hours: 1.5 liters × 5 hours.So, the consumption of one day is: 7 × 1.5 × 5=52.5 unit, is so: 1575 yuan for 1 month.
As seen from Figure 2: in heat pad, material and material in other products are at identical temperature environment borehole cooling, heat pad also maintains more than 40 DEG C in about 250min temperature, and material temperature after 200min, all below 40 DEG C, illustrates that in heat pad, material property can be better than material in other products in other.
