Characteristics and advantages

edit

Features: The main components of silicon powder, active high purity magnesium oxide (MgO), high quality magnesium chloride (MgCl), alkali-resistant fiberglass cloth, excellent flexibility of plant fiber (wood chips), non-combustible light perlite, fly ash, Chemical stability lithopone, high-performance modifier by sheet metal forming machine rolled into sheet, the plate cut into the required size, and then spliced ​​into a combination of high-strength fire-resistant flue.

Advantages: 1, fire performance: the current widespread problem is the finished product smoke pipe fire resistance limit without the national fire statutory testing units for type testing, and part of the cement prefabricated smoke pipe material fire performance, wall thickness does not meet Requirements, combined high-strength fire-resistant flue gas fire resistance performance fully meet the national mandatory provisions of the fire resistance requirements;

2, low cost: Compared with the traditional brick flue, combined high-strength fire-resistant flue can save about 40% of the project cost;

3, light high strength: and cement prefabricated flue and traditional brick flue than the combination of high-strength fire-resistant flue grate light weight, high strength, can significantly reduce the load on the building load;

4, the design flexibility: modular high-strength fire-resistant flue can be reserved according to the size of the hole, at any time to adjust the size of the flue;

5, the design of unique: combination of high-strength fire-resistant flue openings installed on the flue gas check valve and fire isolation doors, can effectively prevent the string and string fire;

6, the construction is simple, an increase of indoor space, good airtight, no return to smoke, do not return to smelly, can greatly improve the indoor environment.

Quality requirements

edit

Apparent density of not less than 1.05 tons / per cubic meter of glass magnesium fire board, the quality should be consistent with "glass magnesium plate" JC688-2006 in the D class above the quality requirements, not halogen.

application

edit

Magnesium oxychloride materials and their products in China as early as in the northeast of the puppet period appeared, nearly 70 years of history. In the development of magnesium chloride cement plate JC / T568 standard, the survey found that a chemical plant in Shandong has paved 60 square meters of magnesium chloride cement floor (has been used for 25 years), in September 1987 dismantling process, test its bending Strength of 6.27MPa, the original ground flexural strength of 8.34MPa, the strength retention rate of 75%
