ICESUN Vacuum Glass LTD. adopts the unique vacuum eye technology to produce Gen3 vacuum glass with mirror eye. This mirror eye technology refers to place the nano active sodium barium film with the size of pupil in the vacuum chamber. When it encounters trace gas, the eye of vacuum glass would immediately undergo chemical reaction and change from black and bright mirror into white powder. The disappearance of the mirror eye indicates the increase of conduction and convection in the vacuum glass, and also indicates that the Low-E film will soon be oxidized and fail, and the radiation heat transfer would greatly increase. That is to say, the building glass will fail. Therefore, users can easily know the service life of their own windows at any time through installing our Vacuum Glass For Buildings. Besides, our company also provide other good quality and high performance Vacuum Glass For Transportation like cars, Vacuum Glass For Passive House, Vacuum Glass For Sun Room and skylight, etc.

Potato fertilizer characteristics
During the whole growth period of the potato, the types and quantities of nutrients required are different due to different stages of growth. At the seedling stage, there is little absorption of fertilizer, and the amount of absorption in the flowering stage increases rapidly, reaching the peak at the beginning of the potato, and then the amount of fertilizer is drastically decreased. The three factors of nitrogen (N), phosphorus (P2O5) and potassium (K2O) were absorbed in each growth period. According to the percentage of total fertilizer absorption, the germination to emergence period were 6.0%, 8.0% and 9.0%, respectively, and the seeding period was 38.0. %, 34.0%, 36.0%, and the potato-forming period was 56.0%, 58.0%, and 55.0%. Among the three factors, potato has the highest absorption of potassium, followed by nitrogen and phosphorus. According to the test, for every 1000kg of tubers produced, it is necessary to absorb 5-6 kg of nitrogen, 1-3 kg of phosphorus pentoxide, and 12-13 kg of potassium oxide.
