Information

Most rubber and plastic pipe insulation materials are used for pipeline insulation. Usually, the most common thing we use is the heat preservation of the copper pipes of the air conditioner, which can reduce the heat loss of the pipes and play a role in energy saving and emission reduction. But in addition, what are the applications of rubber and plastic pipes? Today, the editor will explain to you.

Generally, most of the pipes that need to be insulated are higher temperature or higher temperature pipes. The outer surface of the pipeline is wrapped with rubber and plastic insulation materials, and the main purpose is also to keep warm. The pipes with higher temperature mainly include exhaust flue, cold and hot water pipe, steam pipe and so on.

One is the pipeline that needs to ensure temperature. Steam pipes, hot water pipes (radiator system 75/50 degrees Celsius, boiler heating system generally requires heat preservation for outlet water temperature of 60/50). The temperature of the exhaust air duct and steam exhaust duct in the kitchen is very high, which may reach 150 degrees Celsius, and the temperature of the exhaust air duct reaches 70 or even 280 degrees.

The other is that the heating medium must guarantee certain conditions or parameters. Cooling water, chilled water supply and return water, hot water supply and return water, air-conditioning air supply pipe, processed air-conditioning fresh air pipe, and air-conditioning return air pipe need to be insulated. The exhaust pipe is temporarily unnecessary, because the exhaust air does not need to guarantee certain state parameters.

Then there are pipes that are outdoors to prevent freezing. When installing or laying in a place where there is a risk of freezing. For example, cooling water, hot and cold water outdoor parts, the temperature in winter is very low, there may be a risk of freezing, so insulation is required to prevent freezing. This one is also suitable for outdoor ducts (outdoor ducts are rare now).

In addition, the medium in the pipeline is lower than normal temperature, or even lower than the dew point temperature. These considerations reduce cold loss and prevent condensation on the surface of the pipeline, requiring insulation. Supplementary air duct, in winter, the outdoor temperature is very low, resulting in low surface temperature of the supplementary air duct. Once it reaches the room, it will cause high-temperature indoor air, which may cause condensation when it encounters a cold wall, so the supplementary air duct also needs to be done Insulation.

Therefore, the most common pipes in daily life that need to be insulated by rubber and plastic insulation pipe sleeves are mainly air-conditioning cold and hot water pipes, cooling water pipes, steam heating pipes, etc.

Application of rubber and plastic insulation materials in the field of sound insulation and noise reduction [ 2020-09-22 ]

Sound insulation and noise reduction are a major feature of rubber and plastic insulation materials. Rubber and plastic insulation materials belong to a closed-cell foam structure. Sound waves enter the rubber and plastic, and through the vibration of the bubbles, the sound energy is converted into kinetic energy and then dissipated. Therefore, rubber and plastics have a good noise reduction effect.

State Grid’s annual cumulative electricity consumption achieves positive growth [ 2020-09-22 ]

A few days ago, the cumulative annual electricity consumption of State Grid Corporation of China customers reached 2.96 trillion kWh, an increase of 730 million kWh over the same period last year, an increase of 0.02% year-on-year, and the cumulative growth rate turned positive for the first time this year. Prior to this, the electricity consumption of State Grid customers continued to rise, with a growth rate of 9.8% in August.

What are the properties of rubber and plastic insulation materials and in which areas are they used? [ 2020-09-22 ]

Air conditioning has become an indispensable necessity in people's lives in the hot summer. Many people are curious about how the air conditioner keeps warm on such a hot day? Today, the editor will come to reveal this secret for you. The main insulation material for air conditioners is rubber and plastic. Many people know that rubber and plastics is the most widely used insulation material in the field of air conditioning insulation.

How does rubber-plastic insulation pipe heat and reduce noise? [ 2020-09-22 ]

Rubber-plastic insulation material is a kind of soft and light elastic closed-cell structure insulation material. The most common thing in our daily life is the rubber-plastic pipe in the air-conditioning duct. Of course many friends will say that they have never seen the rubber and plastic tubes on the air conditioner? In fact, what everyone sees is a rubber-plastic tube bound by a cable tie.
