Main features of rock wool pipe
Rock wool pipe shells are suitable for pipe insulation and heat insulation in the industries of electric power, petroleum, metal smelting, and ships (interpretation: general name of ships), especially for small straight pipes, which are convenient and fast to construct. Waterproof rock wool pipe has the special functions of moisture-proof (to prevent mold and deterioration of items), temperature discharge, and water-repellent (function: performance index), especially suitable for use in rainy and humid environments, with a moisture absorption rate of less than 5% and a water-repellent rate of more than 98%. . The waterproof rock wool board is added with waterproof additives in the production (Produce), so that the product has better moisture-proof and hydrophobic properties, and is mainly used in ships, buildings and other occasions that have certain requirements for moisture-proof and fire-proof. The water-repellent rate of waterproof rock wool board is greater than 98%, and the moisture absorption rate is less than 5%. The marine rock wool tube shell and hydrophobic rock wool insulation board are produced with hydrophobic additives, which have good moisture-proof performance. Marine rock wool boards are used for thermal insulation and fire protection of ships; hydrophobic rock wool boards are used for vehicles, mobile equipment, cold storage projects, air conditioning pipes, thermal insulation and fire protection in humid environments, and applications that have certain requirements for moisture resistance.

Important application fields of rock wool (stone wool) shell
The stability of the shell of stone wool (The stability of) and flame resistance put forward strict requirements, which makes the rock wool insulation board develop more rapidly. As a new type of multi-purpose foam material (Material), rock wool tube shell is known for its heat resistance, flame retardant and self-extinguishing, flame penetration resistance,
In case of fire
It has been widely valued for its advantages such as no dripping.
Rock wool (stone wool) shell is made of phenolic (aldehyde) resin (Resin) as the main raw material, adding curing agent, foaming agent and other auxiliary components, while the resin is cross-linked and cured, the foaming agent produces gas dispersion
The foam formed by foaming. The surface of the aluminum silicate shell is smooth, the fibers are long, and the content of slag balls is low, so that the degree of fiber interweaving, delamination resistance, performance, wind erosion resistance, flexibility and tensile strength are all improved, and material loss is reduced. Because it does not contain binder itself, it greatly improves the heat resistance.
Rock wool (stone wool) shell has many excellent properties, the first is heat resistance - the final solidified rock wool shell has a structure that includes several phenol rings and is connected by methylene bridges. It can be known from thermodynamics methylene bridge
organic connection. The closed cell rate of the glass wool shell is more than 92%. Therefore, using polyurethane foam as the insulation layer of the directly buried pipeline can not only play the role of thermal insulation, but also effectively prevent water, moisture and other corrosive liquids, Gas impregnation prevents the growth and development of microorganisms.
The rock wool tube shell is the least affected by temperature and one of the most stable connections, which makes the rock wool insulation board have excellent thermal stability. It can be used for a long time at 150°C, and the instantaneous working temperature can reach 200-300°C
Above, its high temperature resistance
It can be obviously better than other kinds of foam plastics. "Difficult to burn" is also prominent. Phenol molecules are good free radical absorbers. During the pyrolysis process (guò chéng), the free radicals produced (Produce) are rapidly absorbed by the fractured methylene bridges.
phenol molecule
This phenomenon makes the rock wool insulation board extremely difficult to burn; the oxygen (Oxygen) index of the rock wool insulation board is 50, no need to add any flame retardant additives, and the flame retardant grade is flame retardant B1. add
High density with inorganic filler
The oxygen index of the high-strength rock wool (stone wool) shell can reach 70, and the combustion performance meets the requirements of the German DIN4102 building material (Material) non-combustible A2 level. The closed cell rate of the glass wool shell is more than 92%. Therefore, using polyurethane foam as the insulation layer of the directly buried pipeline can not only play the role of thermal insulation, but also effectively prevent water, moisture and other corrosive liquids, Gas impregnation prevents the growth and development of microorganisms. Resistant to flame penetration. According to experts, the rock wool insulation board directly acts on the flame
Under, with carbon formation, without
Dripping, no curling, no melting (definition: the change process of a substance from solid to liquid), the foam basically remains after the flame burns, but a layer of "graphite (chemical formula C) foam" is formed on the surface to effectively protect The foam structure in the layer.
