How to raise muscovy ducks who are afraid of the cold in winter? As adults in winter, the breeding temperature of muscovy ducks should be above 15 ℃, so the first problem is how to keep warm. The suggestion received by Lao Huang is that the high-standard breeding shed must be rebuilt first. Therefore, the heat preservation work of the greenhouse is the key. If you raise this kind of duck in winter, the shed must have a certain thickness, and the roof must be covered with four layers, one layer of plastic film, a layer of blankets on top, and then a layer of insulation cotton. The top layer is for sunscreen. This kind of roof can not only shelter from wind and rain, but also has good thermal insulation. With this kind of top, the temperature in the greenhouse can be maintained at more than ten degrees Celsius in winter.
Roll on the towel and wrap yourself in it. When the baby fish is wrapped in the blanket, the mother continues to sing “lullaby” to put the baby fish to sleep.
3. It can also be used for curing and heat preservation of blades in the wind power industry. Industrial electric blanket has a history of more than several decades because of its environmental protection, low power consumption, adjustable temperature, convenient use and wide use. At present, a new type of intelligent electric blanket has obtained the national patent, and the working principle is similar to that of the electric blanket, such as flexible insulation heating sleeve and so on.
Step 13: after the rice is loaded, dig a well in the middle of the wine tank, almost to the bottom of the well, which is used to observe the output of alcohol, which usually begins to produce wine in a day or two. Cover the lid, seal the wine jar, and finally wrap the wine jar with a quilt or blanket to keep it warm and fermentate. after two days, you can open the lid to see if there is any wine, and then observe it for a week or so. wrap another quilt so as not to affect the fermentation because of the low temperature outside. If you have already produced the wine, it will continue to be sealed, and you can drink after a month, or you can add a little rock sugar, about 100 grams, while opening the lid, which will make the wine sweeter, and if it is too sweet, it will not taste good.
The first is to scientifically implement the work of anti-freezing and heat preservation in waterworks and deep wells of water sources. To strengthen the inspection and thermal insulation protection of the water conveyance and water supply pipeline, the Unicom water pipeline in the ab area of the third waterworks has been discharged and an insulation layer has been added to prevent the pipeline from freezing and cracking. Heat preservation measures such as inspection and pumping, anti-freezing film and blanket blanket are taken for inspection wells of water pipeline network. It ensures the normal operation of the pipeline. The electric heating was opened in 41 deep wells in the first, second and third water sources, ensuring the normal operation of various water supply equipment and facilities.
Cangzhou Chengshengda Pipeline Co., Ltd. wholeheartedly welcomes friends from all walks of life at home and abroad to visit and seek common development. At present, the widely used directly buried steam pipes mainly have the following three representative structural forms: working steel pipe, anti-corrosion coating, fiber insulated pipe (felt), waterproof film, air layer, steel pipe sheath, anti-corrosion coating; working steel pipe, anti-corrosion coating, fiber insulation blanket, fine porous powder insulation block, foam insulation layer (air layer), casing Steel pipe, anticorrosive coating, powdered heat insulation paste, waterproof layer (air layer) and sheath for operation. During the working period, the steel pipe with heat source (working pipe) and the outer protective pipe (which can be made up of steel pipe + anti-corrosion coating).
Set up a special person to measure the temperature, record the temperature measurement in detail, and file it. At the same time, the temperature measurement personnel are responsible for checking the coverage and heat preservation, are familiar with the pouring time of concrete in various parts of the structure, and should strengthen the inspection of the cold blanket coverage in case of strong wind to prevent the cold blanket from blowing by the strong wind. notify the relevant personnel to take effective measures in time if you find something unusual.
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.
But imagine the following, if there is really such a snowcake-like picnic blanket, the picnic you will become the highlight of the crowd, the spirit and spirit of the child fun style is also very unique!
Compared with the furniture at home, the structure of the new car is more complex and the materials are more diverse, so the problem of VOC can not be ignored. Imagine that we spend less than an hour or two in the car every day, and even spend seven or eight hours on long-distance driving. The air quality of the confined space in the car is more related to our daily health. The VOC in the car mainly comes from carpets, dashboard plastic parts, roof blankets, seats and other decorative glue. The plastics, rubber parts, fabrics, paint materials, thermal insulation materials, adhesives and other materials used in the car contain organic solvents, additives and auxiliaries, which will also increase the VOC value inside the car. This does not include the large VOC manufacturers such as floor mats, trunk mats and seat covers installed in the rear market.
