At 9: 00 a.m. on the 17th, at the site of the square cabin hospital, workers are carrying out construction in an orderly manner, and the basic facilities in the cabin are fully equipped. Beds, bedding, electric blankets, towels, toothbrushes, slippers and other daily necessities for patients are being placed one by one. All kinds of medical equipment and medicines are being delivered one after another, and medical personnel are getting familiar with the site.
The high temperature firing section of ℃ (calculated according to the bad theoretical working conditions) according to the high working temperature in the furnace, the thickness of the ceramic fiber module in the hot surface layer and the total thermal insulation thickness, the temperature of the outer wall of the furnace is calculated. The normal operating temperature of high temperature section is ≤ 1050 ℃. The high aluminum ceramic fiber module with long-term working temperature of 1200 ℃ can fully meet the working requirements of the converter and ensure a good service life. Because the temperature of the backing blanket is far away from the hot surface, the common ceramic fiber with a long-term working temperature of 950℃ can meet the requirements.
“whether you go to China or abroad, there must be a pair of very thick cotton socks and knee pads in your bag.” Ms. Lin said. Especially on a long-distance flight, if her shoes are uncomfortable, she will take off her shoes and put on thick socks and knee pads, which can be both comfortable and warm. Blankets may not be supplied on the plane, and shawls can be brought for preparation. Even if there is a blanket, the area is not large, usually it can cover the top, but not the bottom, so the shawl can come in handy.
The index of air pollutants in the car exceeds the standard, and most of the pollution sources are interior fillers and auto accessories, such as leather in seats and foamed sponges, instrument panels, door linings and other plastic accessories, chemical fiber components in roof blankets and floor mats, as well as a variety of binders to be used in the production process.
The outer application of a layer of reflective aluminum foil in the insulation layer can effectively reduce the heat loss of the pipeline and has high reliability. according to the medium temperature, high temperature and ultra-high temperature of the steam medium, high temperature resistant thermal insulation materials such as hydrophobic aluminum silicate blanket / fiber felt or silica aerogel nano thermal insulation felt can be used as layer insulation layer to meet the requirements of high temperature resistance, and / sliding guide support can be used instead of traditional support. It is more beneficial to the free expansion of the working steel pipe in the outer steel pipe, and the special material thermal insulation measures are adopted between the sliding support and the steel pipe, which effectively solves the thermal bridge problem of the steel sleeve steel insulation pipe. The surface temperature of the outer protective layer at the sliding support is lower. It will not destroy the anti-corrosion coating of the pipeline, and the local corrosion of the pipeline will not occur. By pumping the air layer in the traditional prefabricated directly buried steam steel jacket steel insulation pipe into a vacuum layer, the moisture in the air layer and the moisture absorbed in the insulation layer can be removed.
Third, aluminum silicate blankets can be used when heat preservation and insulation are needed in electric power and other high-temperature devices. Fourth, it can be used to heat the pipe in the device. First, the fire prevention work of high-rise buildings needs to be done well, and we can use aluminum silicate blankets as fire insulation materials. Sixth, gas or chemical reactions in high-temperature equipment require large reactors and strong heat resistance, so we can use aluminum silicate blankets as filters. I believe you all have a certain understanding of aluminosilicate fiber blanket, which is an excellent high temperature resistant product, but do you know that the service time of this material is directly related to the temperature? If at the allowable temperature, the crystal growth of the product will be abnormal, and its performance will be better, and it will be able to work for 5-10 years.
