1, Shen Jie pressure cooker lid
Many families have a pressure cooker, but a pressure cooker exploded in the kitchen or burn people's accidents happened quite frequently. In addition to purchasing a pressure cooker then time to focus on the quality of the product, the process should be clear in the use of the characteristics of pressure cooker, and master the correct use.
Is well known that the boiling point of liquid pressure with the liquid surface temperature increased, a pressure cooker that is applied by raising the pressure and made the boiling point of this principle. If the pressure cooker's pressure valve to increase the gravity or the sudden opening of the pressure cooker lid internal pressure would have been a serious security risk. Gas pressure inside the pressure cooker solely by the pressure control valve of the gravity, if gravity to increase pressure valve, increased pressure pot, the boiling point increased. This is very easy to create a pressure cooker exploded, so this practice is strictly prohibited.
Pressure cooker burned food, with its Shaotang example, if the suddenly open the lid, the pan suddenly dropped to 1 atmosphere pressure, the boiling point down to 100 , a large number of sudden vaporization of water and boil rapidly, a large number of high-pressure steam, soup poured forth easily result in scalding injury. So, to quickly and safely open the lid, we must first have a cooling process, the following two cooling options:
The first method is the pressure cooker in water cooling, the second method is to keep the lid on the cold water is poured.
Use the first method, the first cooling the lower pot, the pot bottom and is liquid. While other parts also will Since conduction cooling, this cooling method needing time longer. Use the second method, cold water poured at 120 the lid on the immediate vaporization, evaporation will absorb a lot of heat, and not only because of transmission to other parts of the cooling, and cooling from above so that vapor and liquid flow smoothly, so that more cooling save time.
2, PVC cling film carcinogenic risks
PVC cling film in the country a large number of supermarkets and home use, experts warn, PVC food wrap on the human body are relatively large hazard, need to be used with caution.
Because the PVC cling film is a polyvinyl chloride resin as main raw material, PVC, including chlorine, which is toxic. PVC food wrap has two main aspects of inflicted harm: the high content of vinyl chloride monomer, would evaporate; PVC cling film is the main component of plasticizer used ethyl hexyl amine (DEHA). Precipitation of this material is easy, as the food into the body, causing carcinogenic effects on the human body, especially the cause endocrine, hormonal disorders, so the larger the human body harm. With the food into the human body, have carcinogenic effects on the human body, especially the human endocrine disturbances, cause women to breast cancer, birth defects in newborns, male reproductive disorder or mental disease.
Accordingly, experts recommend buying plastic wrap, you should choose a more secure insurance for PE and PVDC (poly vinyl chloride flat 2) plastic wrap. In addition to identifying the time of purchase carefully wrap the label on the packaging, but also there are ways to distinguish between PVC and PE cling film wrap. The transparency of PVC cling film, stretch and cling film adhesive strength than PE. PVC cling film in the use of fire, the flame black, black smoke, a pungent odor, will not drip and leave after the fire goes out automatically. The PE plastic wrap yellow flame burning, odorless, will drip, and left after the fire to continue burning.
3, microwave radiation human health effect
Microwave at work when the electromagnetic wave to the surrounding emission, or electromagnetic radiation. Due to its wave length, frequency, high energy big, strong biological effects, which can affect the human nervous, endocrine, cardiovascular, blood, reproductive, immune and vision.
