The fire hose is a hose for water delivery at the fire station. According to the material, it can be divided into a lined fire hose and an unlined fire hose. The unlined fire hose has low pressure resistance, large resistance, easy water leakage, easy to mold, short life, suitable for laying in the fire…
In order to meet the needs of the work site can be arbitrarily moved, as a professional fire hose manufacturer we usually use pu lining material. The tube with good softness can be bent and folded at will, and it is convenient to use. In addition, this type of water belt has the advantage that…
Agricultural water belt is one of the items we often use, and it is widely used in agriculture, construction and other fields. It can not only achieve large-area irrigation but also save water. The following describes the precautions in the use of agricultural water belts. The quality of agricultural water belts should…
Many people can’t distinguish between fire hoses and agricultural water belts. Here we explain the essential difference between agricultural water belts and fire hoses. Agricultural water belts and fire hoses are produced in two materials. The materials used in the fire hoses are much more stressed than the agricultural water belts. Therefore, it is proved…
There is some concern about the leaching of chemicals that can give water a plastic taste, PVC pipe is designed to withstand damage from virtually any corrosive chemicals and gases. Because of this, they have no problem transporting water over long periods of time. Some have reported water having a “slightly plastic taste,” but this…
PVC pipe features: good tensile and compressive strength, but its flexibility is not as good as other plastic pipes, excellent corrosion resistance, the price is the cheapest in all kinds of plastic pipes, but the brittle connection at low temperature is bonding and bearing. The rubber ring connection and flange thread connection are mainly used…
The process of inventing PVC is very interesting. This is to say from Germany more than 100 years ago – when electricity was expensive, lighting lamps were generally fueled with acetylene gas. Some German companies believe that acetylene gas is a big market and invests in a large amount of acetylene gas. A new type…
1. Aggregation Properties of Rubber The state in which rubber molecules are brought together is called the aggregation state. Aggregation states can be divided into three states: solid, liquid, and gas. Rubber has liquid properties because the molecular segments of rubber can move relatively freely like low molecular liquids. Rubber has the property of being…
