Peptides Powder is also called Nano Oligopeptide Collagen (OCO, Nano active Oligopeptide Collagen, or Nano Collagen for short), also known as Oligopeptide, micro peptide, short peptide. Small peptides generally refer to oligopeptides composed of 2-3 amino acids, with an average molecular weight of about 300 daltons. The final products of protein (collagen) digestion in the digestive tract are usually small peptides rather than free amino acids. Small peptides can be completely absorbed and enter the blood circulation in the form of two or three peptides. Small peptides play an important role in protein nutrition.

Attention should be paid to the use of atmospheric pressure condensing horizontal hot water boiler before use
The atmospheric pressure condensing horizontal hot water boiler adopts a shell-type three-return, fully wet back structure. The fuel is burnt in the furnace under micro-positive pressure, and the high-temperature flue gas enters the first flue pipe bundle through the back-burning chamber along the furnace urethane, and the second type of tube bundle enters the second tube bundle after the pressure-type front cigarette box is turned 180o, and is discharged into the atmosphere after convective heat transfer. . It provides endless power for heating, domestic water, and production heat.
Although the operation of the atmospheric pressure condensing horizontal hot water boiler is designed according to the automatic control, the county has a perfect protection system, but the boiler operation personnel are still required to be qualified furnace workers, and should strictly follow the post responsibility system and boiler operation rules. To ensure the normal operation of the equipment to ensure the safety and economy of the boiler unit.
Precautions before use of atmospheric pressure condensing horizontal hot water boiler:
1. The boiler control system should be operated correctly according to the instruction manual.
2. The boiler drain line and drain pipe should be connected to the drain drain.
3. The furnace room is arranged reasonably, and the boiler room should be kept dry and clean at all times to prevent the control system from getting wet.
4. Types of fuel: natural gas, city gas, petroleum liquefied gas, light oil, heavy oil.
5. When using diesel oil, it should meet the local temperature. When using heavy oil, it should be preheated to 40~60oC.
6. Power requirements: rated voltage AC.380V, 50Hz. The voltage fluctuation is within ±5% of the rated voltage. A grounding protection wire should be installed when installing the boiler.
7. It is strictly forbidden to place flammable materials such as oil and gas around the boiler. The distance between the oil tank, the gas tank and the outer wall of the boiler room should be more than 15 meters. If there is a special reason to shorten the fire separation distance, it should be approved by the local fire department and relevant departments; if underground layout is adopted, the cover layer should be above 0.5m, and a firewall should be installed around; when underground, the pump anchor bolts must be tightened, or Other measures to prevent oil bar displacement are used.
8. Precautions when piping for atmospheric pressure condensing horizontal hot water boiler :
a. When the boiler is piped, an expansion tank must be provided. The distance between the water tank and the upper surface of the boiler is between 800mm and 1000mm.
b. It is strictly forbidden to install valves on the water supply pipe, vent pipe and expansion pipe of the boiler.
c. Use a circulating water pump to match the boiler.
