Solar hot water pipe casing insulation is a sandwich structure composite insulation pipe, which is composed of an inner PPR hot water pipe, an outer PVC pipe and a central polyurethane foam insulation layer. Polyurethane insulation pipe is a kind of insulation pipe that transports hot water from the water source to the insulation place to achieve the purpose of not changing the temperature of hot water. It is also energy-saving, environmentally friendly, safe, convenient and efficient. and other obvious advantages, so it has been welcomed by the majority of users.
Do I need to insulate my solar hot water pipe casing?
If the outdoor pipe of the solar water heater is not covered with insulation cotton, will it freeze and break?
More and more households are choosing to install solar water heaters. Compared with gas water heaters and electric water heaters, solar water heaters have the advantages of environmental protection, energy saving, and easy to use. But solar water heaters also have their own drawbacks: they can easily freeze in winter, and in cold weather, water pipes placed high in the air can even freeze and burst. Although in some cold cities in the north, solar water heater manufacturers will provide "electric heating antifreeze belts" (also known as "electric heating companions"), which can reduce the probability of outdoor pipes being frozen and cracked, but in actual life, there are still many water heaters installed with electric heating companions that are frozen and cracked.
The current pipe insulation of solar water heaters,
There are three ways in which solar hot water pipe casing insulation can be insulated:
1. Use insulation pipes made of low-pass materials such as foam materials, rubber and plastic materials to isolate the heat transfer inside and outside, and play a role in heat preservation.
Secondly, large-scale solar water heaters (mainly hot water projects and heating projects), in addition to the use of insulation pipes, also mainly use electric heating and insulation to prevent long-term power outages and frost damage to the pipes.
Third, the use of circulating insulation of large-scale solar water heaters (mainly hot water engineering and heating engineering) is also one of the commonly used methods. That is, when the temperature of the pipeline is too low, the hot water in the tank circulates in the pipeline through the circulation of the circulating pump, which plays the role of heat preservation and anti-freezing.
Solar water heater pipe insulation can reduce the heat loss of hot water in the pipeline during use, so as to ensure the temperature quality of hot water; Generally, rubber and plastic insulation pipes are used to wrap the pipes, and then aluminum foil or aluminum skin, PVC pipes are wrapped in the outer layer to prevent aging caused by wind and sun; In the low northern area, because the outdoor temperature is lower than zero in winter, it tends to freeze, so you can place a "solar heat trace" in the insulation layer of the pipeline to turn on at a temperature below 5 °C to heat and prevent freezing.
In many fields such as industrial protection and building waterproofing, polyurea materials have been widely used for their excellent performance advantages. In order to give full play to the characteristics of polyurea materials, a high-performance spraying equipment is crucial, and the CNMC-A25 po
