A diligence: It is a patrol pool. The swimming pool is visited 3 times a day. After watching the food in the morning, the pool is observed. At noon the pool is watched for changes in water temperature. At night, the pool is observed for adult food intake.
In the morning: It is early stocking and early eating. Pay attention to whether or not you are eating when the water temperature rises after the Spring Festival. If you do not eat food, you should use warming to feed the adult as soon as possible.
Three look; it is to look at food intake, to see if there is food or food, and see the water quality. Looking at food intake is mainly to see whether the food intake of adults is concentrated or scattered. To see if there is food or food spit, in order to adjust the amount of feeding. Water quality is mainly to see if the water quality is fresh and the transparency is high, so that measures can be taken to improve the water quality.
Four defenses: It is heatstroke prevention, disease prevention, escape prevention, and waterproof change.
Heatstroke prevention is one of the important tasks of summer adult pool management. Due to the high water temperature in summer and the death of adults, it is necessary to adopt anti-cold cooling to facilitate the growth of giant salamanders, and outdoor sun protection is mainly used to set shades to make the light intensity low. Change the water to be taken late at night, so that it is beneficial for the body to “summerâ€.
Prevention of disease is to prevent the baby fish disease. Attention should be paid to the feeding behavior of the giant salamanders. If adults are found to be outliers, they must be examined and studied for disease conditions, and isolation and prevention measures should be used to promptly treat them.
Anti-escape is to prevent adults from escaping. We must constantly inspect the water inlet and outlet, strengthen management, and prevent escape.
Waterproof is to prevent water quality from getting worse.
Hyaluronic Acid For Skin, Sodium Hyaluronate is well known as the best [Natural Moisturizing Factor". For Hyaluronic Acid Cream . In the early 1980s, the excellent moisturizing function of Sodium Hyaluronate has been widely concerned by international cosmetics industry. With its unique film-forming and hydrating characteristics, Hyaluronic Acid Powder Cosmetic Grade is used as a highly effective humectants in cosmetics. It attracts moisture to the skin and hold moisture in the skin, which preserve skin smoothness, suppleness and elasticity. 1 gram of Hyaluronic Acid Powder Cosmetic Grade is able to retain up to 1000 gram of water. So it is regarded as the [key to the fountain of youth".
The effects are as follows:
(1) Moisturizing effect
Moisturizing is the most important effect of Sodium Hyaluronate in cosmetics products. It can be hydrated shell
in skin surface and make the corneum hydration and softening. Compared with
other humectants, Sodium Hyaluronate is less effected by the environment as it
has the highest hygroscopic capacity in a relatively low humidity (e.g., in a
dry winter), but has the lowest hygroscopic capacity in a relatively high
humidity (e.g., in a damp summer). This unique property of Sodium Hyaluronate
makes the skin adapt to different seasons.
(2) Skin nutrition effect
Sodium Hyaluronate is the inherent biological materials of skin. The exogenous
Sodium Hyaluronate can complement the endogenous Sodium Hyaluronate. Low molecular Sodium Hyaluronate can
penetrate into dermis directly to improve the nutrient supply.
(3) Skin repair effect
There is some evidence that topically applied Sodium Hyaluronate can reduce
skin irritation
from various causes. During clinical trials it was also shown that this
ingredient is effective in promoting healing and fighting inflammatory
conditions of the skin. Sodium Hyaluronate serves as a free radical scavenger
and antioxidant, helping to protect the skin from the aging effects of
excessive sunlight exposure.
(4) Emollient and Film-forming
Sodium Hyaluronate is high polymer with high lubrication and film-forming.
Sodium Hyaluronate contained in cosmetics creates protective film on the
surface of skin, which retains moisture, and at the same time prevents moisture
in the skin from evaporation, so that improves freshness of the skin.
(5) Thickening
Sodium Hyaluronate solution have
high viscosity, and 1% solution is gelatinous. It can be added to cosmetics to
improve the thickening and stability.
