one: the low thermal conductivity

When the average temperature of 0 ℃, this material coefficient of thermal conductivity is 0.034 W/mk, and its surface exothermic coefficient is high, so in the same external conditions, the use of this product thickness more than half than other heat preservation material can achieve the same effect of heat preservation, thereby saving the ceiling above the floor, save investment.

two: flame retardant performance is good

This material contains a large amount of flame retardant smoke reduction material, produced by the combustion smoke density is extremely low, and in case of fire don't melt, don't drop the burning fireball, materials since the quench characteristics.

According to GB8624-1997 "building materials combustion performance grading method", this product is a B1 level flame retardant materials, to ensure safe and reliable.

Three: closed-cell foam, moistureproof performance is good

1: glass fiber: open pore structure high water vapor permeability, leading to longer duration of use, also with higher thermal conductivity, the heat preservation effect is reduced greatly.

2: foaming polyethylene (PEF) : even the pore structure, has a high water vapor permeability, the material of hard and brittle, easy breakage and short service life.

3: China rubber: obturator structure with minimal water vapor permeability, can keep the low coefficient of thermal conductivity for a long time.

Four: good seismic performance

Shenzhou rubber insulation material with high elasticity, and thus can minimize chilled water and hot water pipes in the process of using vibration and resonance.

Five: flexible performance

China rubber and plastic materials with good strength and toughness, bending and irregular pipe construction of easy processing, and can save material.

Six: easy installation, beautiful appearance

Because this product is rich flexibility, easy to install and convenient. Pipe installation: can be put on after the installation together, also can use this glue of the reoccupy after pipe lengthwise. The valve, tee, elbow and other complex components, can clean the plate after cutting, according to the different shapes on the package glue, to ensure the rigor of the whole system, thus ensuring the heat preservation of the entire system. And because of this material are rubber surface smooth level off, and the excellent properties of itself, does not need additional steam insulation layer, protective layer, reduce the trouble of construction, also ensure the beautiful appearance, smooth.

When the equipment or pipeline maintenance, stripping down the material can be reused, performance remains the same.

seven:Other advantages:

China rubber insulation is very safe to use and will not stimulate the skin, also not a health hazard. They can prevent mould to grow, avoid pests or mouse bite, and acid and alkali resistance, superior performance. These performance ideal makes the shenzhou rubber protection pipe insulation, prevent them from corrosion by atmospheric medium or industrial environment.

Determine the thickness of heat preservation material factor:
1, the environment temperature is higher, the thicker the material;
2, the relative humidity is bigger, the material is thicker;
3, medium temperature is lower, the thicker the material;
4, the bigger the pipe diameter, the thicker the material.
