Walnut tree insulation antifreeze essentials

The 1-2 year old saplings that can not safely overwinter in the open field will bend the whole tree to one side and cover the soil. This method is the most effective and reliable measure to prevent the pumping. A mound of soil is cultivated within 30 cm of the base of the seedling to prevent frostbite and grafting. In the coming spring, when the temperature rises and stabilizes, it is removed and the tree is flattened.

Whitening cold-proof saplings can alleviate the temperature difference between the yin and yang of the trunk, and the cold-proof effect is better. It can be applied before the soil is frozen. The formula of the whitening agent is: 0.5 kg of salt, 6 kg of quicklime, 15 kg of fresh water, and then added with a proper amount of adhesive and residue of stone sulphur mixture to spread the young branches.

Spraying the medicinal tree with the general protection of the tree and adding 30 kg of water to dilute the sprayed fruit trees to prevent freezing. Add 40~50 kg of water to dilute the sprayed fruit branches to prevent spring cold. (earth)

HC-134A is a hydrocarbon refrigerant blend. The primary ingredients are hydrocarbons, which are flammable substances such as propane and butane. HC-134a  is available in 30 LB cylinders. Automotive refrigerants that leak out of A/C systems contribute very little to the overall global warming problem.

The U.S. EPA has issued regulations that call for R134a to be phased out of domestic new car production by 2021. R134a will still be allowed for certain export vehicles, but only until 2025. After that, all new vehicles will have to use HC-134A refrigerant. HC-134A is flammable, but the new refrigerant is safe for automotive passenger car use. The risk of fire is extremely remote in case of an accident or refrigerant leak into the passenger compartment.

Application: Replacement refrigerant of R134A.
