Fire-retardant casing features and advantages

2016-01-13


Production process: fire-retardant casing made of alkali-free glass fiber spinning yarn and weaving machines weave into the casing pipe, after artificial coated vinyl red iron oxide silica gel via high temperature oven heat treated together.

Performance: fire resistance, high-temperature, heat insulation, heat preservation, insulation properties. At 300? C within the long-term use after installation, fire insulation effect. Temperatures in excess of 300 in an instant? C (for example: molten metal spatter) will not damage the wall, tube products have very good protection. Meanwhile, the product has the characteristics of oil-resistant, corrosion-resistant, acid-resistant and alkali, in such a harsh environment or long-term use.

Use of safety and environmental protection

Alkali-free glass fiber with exceptionally strong pulling, no wrinkling fracture resistance, curing, smokeless, halogen nontoxic, nonflammable, good insulating properties of pure oxygen, and then by grade a vinyl liquid silicone rubber coating cured, use process will not produce harmful toxic substances, effective protection of workers ' health in the work environment, avoiding the occurrence of occupational diseases. Unlike asbestos products and other products used in the process will produce large amounts of toxic and hazardous substances, dangerous inhaled on the human body. Meanwhile, asbestos products has an impact on the surrounding environment.

Superior high temperature performance

Fire-retardant casing material is made of vinyl silicone rubber molecules, vinyl chain contains both "organic groups--vinyl", but also "inorganic structure-methyl", a special molecular structure so that it firmly together, in particular high temperature ambient temperature does not change due to temperature changes in molecular composition, to high temperature properties. Silicon-oxygen (Si-O) key chains, the c-c bond is 82.6 kcal/mole, SI-o bond in the silicone for 121,000 kcal/mole, so at higher temperatures or in radiation environments is not broken, do not break down the chemical bonds of molecules. Methyl vinyl silicone rubber not only at high temperatures up to 300? Around doesn't spoil in the heat to melt and low temperature resistance,-75? C low temperature environment can long-term use, not affected by temperature change characteristics of silica gel, wrinkle, no broken, physical and chemical properties are not changed.

Splash-proof, multiple protection

In modern high temperature processing industries in the production process, working temperature is very high, very prone to melting temperature spray, makes the equipment required for the production of pipes and wires erosion damage. In this way, not only production equipment is often caused by damage to pipe line stagnated, and it can lead to a large number of production waste of resources, affect the normal production. Electric company for long-term testing in proportion, through several organic silica gel coated with fire-retardant casing, not only products of the highest temperature reached 1300? C implement multiple security, can effectively block the molten iron, molten copper, aluminium and other high temperature molten splash, to prevent the cable and equipment were damaged.

Radiation resistance of thermal insulating, stable long-term protection effect

In the environment of high temperature workshop, lots of pipes, valves, or the internal temperature of the device is very high, is likely to cause heat loss makes production equipment operating temperature up to job requirements; in addition, the outer wall of the valve is easy due to the thermal properties of the material temperature is too high, easily causing burns. Electric companies in the production of fire-retardant casing, have better thermal stability and thermal insulation, ensure equipment normal use effective work to achieve energy saving effect. More can effectively prevent the occurrence of accidents, to effective protection.

Aging-oil moisture-proof, extend equipment life

Electric companies in the production of fire-retardant casing has a strong chemical stability, grade a vinyl silicone rubber to oil, acid and alkaline substances produced by chemical reactions, such as extremely low, less than 300 ℃, long-term use and is not aging, service life of up to dozens of years in the natural environment to maximize the protection of pipelines, cables and equipment in these harsh environments, greatly extending its service life.

Resistant to pressure and ARC resistance and ozone, guarantee line pipe insulation

Grade a vinyl silicone rubber coating on the surface, the molecules of chemical chain-Si-O-, unique key exists, it is not easy to be broken down by ultraviolet light and ozone. Fire-retardant casing has good electrical insulation properties, resistant to pressure up to 25KV, dielectric loss, resistance to voltage, arc, Corona-resistant, volume resistivity and surface resistivity of insulating material in the top, and their electrical properties under the influence of temperature and frequency is very small. Therefore, they are a stable electrical insulating material, is widely used in the electronics and electrical industry.

Flame spread fire prevention, safety rest assured

If the pipe conveyor is flammable or toxic media leak likely to cause a fire or cause death; cables are also susceptible to high temperature combustion; fire-retardant casing using heat-resistant up to 600 ° c of e-glass fiber woven together, added silicone on the surface have the appropriate flame retardants and other special materials, so that it has excellent flame resistance. Even when the fire occurred, can prevent the spread of the fire has been able to protect internal lines intact for a long time, to data, information, and other important information rescue possible, and plenty of time.

Install using the convenient

Fire Sleeve-sleeve and ribbon-type, cannot stop job when it comes to production equipment or installation is not easy cases, you would need to use Ribbon-type fire retardant casing. Installation without disassembly of pipes and cables, easily reassembled. Another advantage of factory installed to ensure correct fit and the integrity of the structure.
