If there is no place to dry quilts in the community, you can find your own way, put a high chair on the balcony, put the quilt on it to dry, or buy a special rack for drying quilts, and take it outside to dry the quilt when there is sun. There are always more ways than difficulties, as long as you think of a way, there will always be a way.

Hello, in response to your question I suggest that you can buy a folding hanger online and dry it on the balcony at home.

Discharge cooling is another type of convection cooling. Unlike regenerative cooling, the coolant used for exhaust cooling absorbs heat to the thrust chamber and is discharged out of the combustion chamber instead of entering the combustion chamber to participate in combustion. Direct drain coolant reduces the thrust chamber specific impulse, so the coolant flow for drain cooling needs to be minimized while only using drain cooling at the outlet section of the nozzle that is relatively less heated.
There is also radiative cooling, in which the heat flow is transferred from the combustion products to the thrust chamber, and then the heat is radiated by the thrust chamber wall to the surrounding space. Radiative cooling is characterized by simplicity and small structural mass. It is mainly used in the extension section of large nozzles and the thrust chamber of small thrust engines using high-temperature resistant materials.
When cooling in the thrust chamber of the tissue, a relatively low temperature liquid or gas protective layer is established on the surface of the thrust chamber wall to reduce the heat flow to the thrust chamber wall, reduce the wall temperature, and achieve cooling. Internal cooling is mainly divided into three methods: internal cooling (shield cooling), membrane cooling and diaphoretic cooling of head tissues. After the internal cooling measures are adopted in the thrust chamber, the mixing ratio near the wall of the combustion chamber is different from the optimal mixing ratio in the central area (in most cases, the near-wall layer rich in fuel is used) due to the need to reduce the temperature of the protective layer, resulting in the uneven distribution of the mixing ratio along the cross-section of the combustion chamber, so that the combustion efficiency is reduced to a certain extent.
Membrane cooling is similar to shield cooling in that it cools the thrust chamber wall by establishing a uniform and stable coolant film or air film protective layer near the inner wall surface, except that the coolant used to establish the protective layer is not injected by the injector, but is supplied through a special cooling belt. The cooling band is generally arranged in a cross-section of the combustion chamber or the convergence section of the nozzle. There can be several cooling bands along the length of the combustion chamber.
In order to improve the stability of the membrane, the coolant often flows through the gaps or small holes in the cooling belts, and when sweating is used, the thrust chamber wall or part of the inner wall is made of porous material with a pore diameter of tens of microns. Porous materials are usually sintered with metal powders or pressed with metal mesh. In this case, the number of pores per unit area is increased by making the micropores in the material as evenly distributed as possible.
The liquid coolant penetrates into the inner wall, creating a protective film that reduces the density of the heat transferred to the wall. When the flow rate of liquid coolant used for sweat cooling is above a certain threshold, a liquid film is formed near the wall of the thrust chamber. When the coolant flow rate is below the critical flow, the inner wall temperature will be higher than the coolant boiling point at the current pressure, and some or all of the coolant will evaporate, forming an air film.
In addition to the above thermal protection, there are other thermal protection methods such as: ablation cooling, thermal insulation cooling, hot melt cooling and composite protection of chamber walls. 3. Thermal protection scheme of high enthalpy gas generator Based on the above methods and the actual situation, the thermal protection method of high enthalpy gas generator is obtained.
The combustion chamber of a high-enthalpy gas generator differs from that of a liquid rocket engine, eliminating the front thrust chamber part, making its structure simpler and more effective. Then, the thermal protection involved is the thermal protection part of the combustion chamber wall. As the fuel enters the combustion chamber, it quickly decomposes and releases large quantities.

If you have the conditions, you can buy an electric mattress, as long as the quilt is spread on the electric mattress, turn on the high temperature, turn it over once in half an hour, and repeat it several times, as long as you feel that it is not damp, but you must pay attention to safety, you can't open it for a long time and don't look at it, it is easy to catch fire. It is advisable to do this, and pay attention to the electric mattress when no one is around.

1. You can go to the supermarket to buy a dehumidification box or dehumidification bag, which is more common.
2. If we have a dehumidifier at home, we can use it.
3. You can use laundry detergent to absorb moisture, but the amount is large, but you can reuse it to wash clothes.
4. You can use a hair dryer, then wrap the soap in a napkin, and smear the quilt, but it can only be emergency, and it must be washed when the weather is good.
5. You can turn on the air conditioner, which is also suitable for hotels.

Legal Analysis: Ask the property for help. However, property service companies do not need to be responsible, but have the obligation to assist and cooperate with the investigation of relevant departments.
Legal basis: Property Management Regulations" Article 35 Property service enterprises shall provide corresponding services in accordance with the provisions of the property service contract. Where a property management service enterprise fails to perform the provisions of the property management service contract, resulting in damage to the owner's personal and property safety, it shall bear corresponding legal responsibility in accordance with law.
The tenon hole is widened, and there are two ways to remedy it. One is to make a tenon according to the existing tenon hole; The second is to make a filler according to the size of the existing mortise and tenon hole, and the mortise and tenon hole will be filled with woodworking glue, and the tenon hole will be opened in the position or the original position after the glue is dried.
