Problems solved by technology

[0007] At 07:52 on September 26, 2011, a fire broke out in the anti-oxidation section of the vertical continuous electroplating equipment located in the electroplating workshop of an Electronics Co., Ltd. in Wuxi City, Jiangsu Province. Due to the presence of flammable crystals in the PVC ventilation pipe, its own characteristics spread quickly, and During the burning process, toxic and corrosive dense smoke is easily produced. In addition to the fire fighting water, the whole fire caused the loss of buildings, machinery and equipment and inventory. The workshop area is about 12,600 square meters, and the fire area of ​​this accident is about 3,500 square meters. Meter
The smoke and dust after the fire cannot be completely cleaned by using the existing cleaning agent, and at the same time, its pungent smell is also a serious damage to the body of the staff involved in the post-disaster reconstruction
The cleaning effect is not good, and when the cleaning speed is slow, the residual smoke and dust after the fire will cause huge damage to precision instruments, and some instruments that could have been repaired will be scrapped directly, making the losses caused by the fire irreparable, causing great harm to enterprises, insurance companies and even the government. bring a heavy burden

preparation example Construction

[0110] 1. Preparation of samples. A flammable liquid combustion and smoke collection device developed by the Tianjin Fire Research Institute of the Ministry of Public Security was used to simulate the fire environment. The standard ignition source is a mixture of 250mL No. 93 Shell gasoline and 250g PVC pipe. Place a 50mm×50mm PCB board on the sampling board. After the fire source is burned out, use the NJCL-H chloride ion content rapid tester to measure the chloride ion content on the PCB board. The chloride ion content is about 200mg / cm 2 The PCB board as a sample.

[0111] 2. Soot cleaning ability. The chloride ion content of the sample is about 200mg / cm 2 . Mix the example and deionized water evenly at a volume ratio of 1:40. After soaking with dust-free paper, wipe the surface of the sample once or twice, and then wipe it once with a new piece of dust-free paper soaked in deionized water. Use a microscope to observe the smoke and dust residues. Among the 10 samples, ...

Embodiment 1

[0118] The compound shown in formula (A) is selected from ethylene glycol monobutyl ether, the compound shown in formula (B) is selected from AEO-9, the compound shown in formula (C) is selected from sodium hydroxide, and the compound shown in formula (D) is selected from The compound shown is selected from potassium oleate, the compound shown in formula (E) is selected from monoethanolamine, sodium olefin sulfonate is selected from AOS, and Tween is selected from Tween 20.

[0119] Based on 100 parts by weight of the cleaning agent, the post-fire smoke cleaning agent contains 10 parts of ethylene glycol monobutyl ether, 0.75 parts of AEO-9, 3 parts of sodium hydroxide, 0.15 parts of potassium oleate, 8.4 parts of monoethanolamine, and 4 parts of AOS 1.5 parts of Tween 20, 1 part of tetrasodium edetate, and the balance of water.

Embodiment 2

[0121] Same as Example 1, except that the compound represented by formula (A) is selected from ethylene glycol monoisobutyl ether.

Abstract

The invention provides a smoke dust cleaning agent after fire hazards. Every 100 parts by weight of the cleaning agent at least contains 8-12 parts of compounds disclosed as Formula (A), 0.5-1 part of compounds disclosed as Formula (B), 2-4 parts of compounds disclosed as Formula (C), 0.1-0.2 parts of compounds disclosed as Formula (D), 8-10 parts of compounds disclosed as Formula (E), 3-5 parts of sodium olefinsulfonate, 1-2 parts of Tween, 0.5-2 parts of tetrasodium ethylenediamine tetraacetate and the balance of water. In R1-O-(CH2CH2O)x-H (A), R1 is C1-C10 alkyl, and x is a positive integer ranging from 1 to 10. In R2-O-(CH2CH2O)y-H (B), R2 is C1-C30 alkyl, and y is a positive integer ranging from 1 to 20, In M1OH (C), M1 is alkali metal or alkali earth metal. In Formula (D), R3 is C1-C29 alkyl, and M2 is alkali metal or alkali earth metal. In H2N-R4 (E), R4 is a C1-C10 substituent group containing 1 hydroxyl.

Description

technical field [0001] The invention relates to the field of post-fire reconstruction, in particular to a post-fire soot cleaning agent, and also relates to a method for using the post-fire soot cleaning agent. Background technique [0002] Fire refers to the disaster caused by burning out of control in time or space. Among various disasters, fire is one of the main disasters that most frequently and commonly threaten public safety and social development. [0003] At 6:04 am on September 5, 2012, a fire broke out in an internationally renowned American-funded multinational group located in Jiulong Town, Luogang District, Guangzhou City. It is a global leader in circuit board production and electronic manufacturing services. St. Louis, Missouri, USA, has set up 18 factories in 6 countries on three continents (Europe, Asia, and North America). The fire affected assets of about 1.275 billion yuan and an area of ​​about 100,000 square meters. [0004] At 12:40 on May 11, 2012,...
