Thermal Insulation Vacuum Glass
Compared with the ordinary insulating glass, the thermal insulation vacuum glass from ICESUN has good sun-proof and heat insulation performance. When the sunshine is exposed through the window in summer, the Low-E coating in ICESUN vacuum glass products can effectively reflect infrared rays and block the heat out of the window. The vacuum degree between the glasses is 10-4 Pa, so the thermal convection no longer exists, the heat conduction is reduced to the limit, and the Low-E layer reflects more than 95% of the infrared radiation. Therefore, the heat between the inner and outer glass plates cannot be exchanged, achieving excellent thermal insulation effect. Just turn on the air conditioner for a short time every day to ensure the cool of the indoor day. So Energy Saving Vacuum Glass can not only save electricity, but also keep users away from the trouble of air conditioning diseases. Besides, ICESUN Vacuum Glass LTD. has also released a series of energy saving vacuum glass for environmental protection, including Sound Proof Vacuum Glass, Anti-radiation Vacuum Glass, Sun Proof Vacuum Glass and so on.

The first application of excessive nitrogen fertilizer can lead to a decline in the quality of the vegetables. Mainly in the increase of nitrogen fertilizer application, the content of vitamin C and soluble total sugar in vegetables will decrease significantly. Specifically, it is expressed in vegetables. For example, under high nitrogen conditions, the sugar acidity of the fruit is significantly decreased, the palatability is deteriorated, the quality is deteriorated, the soluble solids in the fruit are also decreased, and the fruit is mashed, making the tomato intolerant. Shipped. At the same time, excessive application of nitrogen fertilizer in vegetables will also significantly reduce nutrients such as magnesium in vegetables and their fruits.
Secondly, excessive application of nitrogen fertilizer can significantly increase the nitrate content in vegetables, and the nitrite ions reduced by humans after eating vegetables are harmful to the human body. Nitrite ion is a strong carcinogen and causes cancer after long-term consumption.

Excessive use of nitrogen fertilizer in vegetables
Nitrogen fertilizer is the main fertilizer in vegetable production. Rational application of nitrogen fertilizer can increase the yield of vegetables, but the application rate of nitrogen fertilizer on vegetables is limited. When it exceeds a certain amount, it will not only cause the yield and quality of vegetables to decline, but also Produce harmful substances.
