AI Technical Summary

Problems solved by technology

However, rock wool particles cannot withstand the high temperature of 1000°C, and the fire temperature is higher than this temperature. Therefore, when a fire occurs, the ordinary fire-resistant package is useless and cannot achieve the purpose of fire prevention and fire resistance.

Embodiment 1

[0009] (1) Weighing ingredients: Before batching, the weighing scale must be calibrated, and various raw materials can be measured after calibration. The ingredients are weighed according to 45.0% of aluminum silicate fiber cotton particles and 55.0% of raw vermiculite. (2) Stirring and filling: Measure the aluminum silicate fiber cotton particles and vermiculite required for a single fire retardant bag with a corresponding self-made measuring cup, pour into the container, then stir, and fill a single fire retardant bag. (3) Sealing of the fire-resistant bag: Use a special sewing machine to sew and seal the measured small bag package. There must be no skipped stitches, tension, or leaks at the seam. When sealing, the air in the fire-resistant bag should be squeezed out as much as possible. (4) Inspection and warehousing: The personnel of the quality inspection department will conduct inspections, and only after passing the test can they be packaged and put into storage.

Embodiment 2

[0011] (1) Weighing and batching: Before batching, the weighing scale must be calibrated, and various raw materials can be measured after calibration, and the batching is weighed according to 46.0% of aluminum silicate fiber cotton particles and 54.0% of raw vermiculite. (2) Stirring and filling: Measure the aluminum silicate fiber cotton particles and vermiculite required for a single fire retardant bag with a corresponding self-made measuring cup, pour into the container, then stir, and fill a single fire retardant bag. (3) Sealing of the fire-resistant bag Use a special sewing machine to sew and seal the measured small bag package. There must be no skipped stitches, tension, or leaks at the seam. When sealing, the air in the fire-resistant bag should be forced as much as possible. (4) Inspection and warehousing: The personnel of the quality inspection department will conduct inspections, and only after passing the test can they be packaged and put into storage.

Abstract

The invention relates to a method for manufacturing a high-temperature-resistant fire-resistant package. The raw material formula is composed by weight percentage: 40.0%-50.0% of aluminum silicate fiber cotton particles; 50.0%-60.0% of raw vermiculite. The manufacturing steps are as follows: (1) weighing ingredients—(2) stirring and filling—(3) sealing the fire retardant bag—(4) inspecting and storing. The invention provides a fire-resistant package widely used in electric power, metallurgy, petrochemical, construction and other industries, which can withstand high temperatures above 1000°C. It can be dismantled and reused again.

Description

1. Technical field [0001] The invention relates to a method for manufacturing a fire-resistant bag, in particular to a method for manufacturing a high-temperature-resistant fire-resistant bag. 2. Background technology [0002] At present, fire retardant bags used in wire and cable fire protection engineering mainly use rock wool particles, hydroxyethyl cellulose and raw vermiculite as raw materials to manufacture fire retardant bags, such as the intumescent cable fire retardant bag applied by Shengxian Cable Fireproof Accessories Factory Chinese patent CN1073707, its raw materials are: non-combustible refractory materials rock wool, diatomaceous earth, organic silicon adhesive and raw vermiculite, etc.; the Chinese patent CN1565673 of the fire retardant bag published by the Sichuan Fire Research Institute of the Ministry of Public Security, its raw materials For: chlorine partial emulsion 10% ~ 20%, ammonium polyphosphate flame retardant 15% ~ 25%, expanded graphite 6% ~ 16%...
