If there is too much wood, tannic acid and humic acid will be decomposed after being soaked for a long time. Although it will not cause direct harm to living things, it is rich in pigments. Therefore, you should wash the wood after you buy it. If possible, you'd better cook it for anti-virus purposes, and then soak it in water. During this period, you should change the water frequently, or directly soak it in flowing water. Pay attention to observation and prevent possible decay. It will take a long time to use the submerged wood after it stops spitting. If there is too much lignin, it may take 1-2 years to stop spitting. If it is used in a hurry, it is necessary to change water and add activated carbon frequently to dilute the pigment. Matters needing attention in home improvement?

Use less wood-based panels and more glass. Conciseness is the main thing.

understanding the structure of a house 1. Knowing the structure of your house, measuring the actual area, drawing a detailed structural diagram, knowing the specific layout (including reasonable changes to the original structure) and the total cost of decoration (including the price of materials and labor costs) can give you a general idea of how to decorate your house. 2 Fund preparation: Generally speaking, the total cost of decoration should be 1% to 2% of the house price. 3. Material budget and cost allocation: At present, people are based on the pursuit of comfort, and the reasonable allocation ratio of material cost is: bathroom and cupboard room account for 45%, hall for 35%, and bedroom for 2%. 4. Preparation for construction period: Take two bedrooms and one living room as an example. Under normal circumstances, the construction period is about 3 days, and if other factors, such as changing the design scheme, are taken into account, it will take up to 4 days. 5, professional knowledge preparation. Diving, diving, diving again. Study, study, and study again. 2. Market research: L. Investigation of basic price. A) Design and construction prices, check online, and run the decoration market. B Only by having a preliminary understanding of the price of materials and the building materials market can we have a good idea and be comfortable in the decoration operation. 2. Have a comprehensive understanding of the situation of the home decoration market. Whether you choose a company or a construction team, you should know something about their integrity and construction quality. You can check it online, watch it on the spot and listen to the feedback from the completed owners. Prevent being cheated. Three steps for home improvement: 1. Make plans and choose grades. 2 planning and design, reasonable layout. Provide a list of items to be placed; 3 understand the market, master the price 4, sign a contract and bind each other: avoid complaints; 5. Check and accept the project against the contract: find the problem and solve it in time. 4. How to prevent excessive decoration According to the investigation of relevant departments, at present, more than 6% of home decoration has the problem of' excessive decoration' to varying degrees. The so-called' excessive decoration' means that the proportion of investment is too large, more indoor space is occupied, the original building structure is seriously damaged, and more toxic and harmful materials are used. From the analysis, there are several reasons for the excessive home decoration: too much listening to the opinions of the decoration company, the decoration company, of course, wants to build more and invest more, so it is inevitable to favor' full bloom' or even' gild the lily' in the home decoration scheme. In this regard, the owner should have sufficient psychological equipment, grasp the principle of' simplifying the complex', and do not blindly' add additional budget investment' with the decoration company. The positions of' protection' and' care' are reversed. In hotels and restaurants, because there are many visitors, the decoration first considers the protection of the environment, such as sticking tablecloths, repairing dados, sticking hard granite on the ground, and installing wall lamps higher. At home, the host will naturally take good care of the indoor environment, so there is no need to stick tablecloths all over the wall, repair dado and stick heavy granite to the ground. Ignoring the problem of a large number of furniture' moving in' after renovation, as far as home is concerned, the living area of most people is not large, and furniture generally accounts for about 5% of the total area. Take the bedroom as an example. In addition to the double bed and wardrobe, some families also have furniture such as TV cabinets, dressing tables, writing desks and sofas. In this way, from the wall to the ground, it is covered by furniture. Therefore, for smaller bedrooms, there is really no need to' go to war' in decoration. Blind comparison and imitation Some people have seen some decoration examples or decoration atlases, and then imitate them stiffly, regardless of whether their rooms have the conditions. Nowadays, the interior of most houses is only 2.6-2.8 meters high, so it is not very suitable to decorate the ceiling. Even if the roof you hang out is beautiful, it will easily give people a sense of oppression. It is better to stick some wood or gypsum ornaments instead. The decoration materials of large rooms blindly pursue high-grade large rooms, which gives people a sense of spaciousness, comfort and value. The important thing is that the decoration should be practical, pleasant in shape and color, and the high-grade materials may not be fully used. One or two sides (such as the ground and the main wall) can be made of high-grade materials, and the rest can be simplified, saving 1 yuan per square meter for decoration, which is not a small number. It is more practical and beautiful to buy some high-grade furniture and electrical appliances with the money saved. 5. What can't be dismantled or changed or need to be cautious? (1) Load-bearing wall: The load-bearing wall can't be dismantled and changed during decoration. What kind of wall is a load-bearing wall? Generally, in buildings with' brick-concrete' structure, all prefabricated walls can't be removed or opened. Brick walls with a thickness of more than 24 cm cannot be demolished. These are load-bearing walls. If you open the door and open the window on the load-bearing wall, it will destroy the load-bearing of the wall, and it is not allowed. (2) Steel bars in the wall: If the building structure is compared with the adult body, the steel bars in the wall are human bones and muscles. If the steel bars are destroyed when laying pipelines, it will affect the bearing capacity of walls and floors. If there is an earthquake, such walls and floors will easily collapse and break. In hydropower reconstruction, the wall should not be slotted horizontally. (3) Beams and columns in the room: Beams and columns are used to support the upper floor. After being removed, the upper floor will fall off, so it cannot be moved. (4) Low wall beside the balcony: there is a door and a window on the wall between the general room and the balcony. These doors and windows can be removed and modified, but the wall below the window cannot be moved. This section of the wall is called the' counterweight wall', which plays the role of stirring up the balcony like thallium. Demolition and alteration of this wall will reduce the bearing capacity of the balcony and lead to the balcony falling. (5) Door: The door frame of the door is embedded in concrete. If it is demolished, it will destroy the building structure and reduce the safety factor. Moreover, it destroyed the building structure at the door, making it more difficult to reinstall the new door. (6) Waterproof layers in bathrooms and kitchens: There are waterproof layers under the ground in these places. If they are damaged, the downstairs will become' water curtain cave'. Therefore, when replacing the ground material, we must be careful not to destroy the waterproof layer. If it is rebuilt after being destroyed, we must do a '24-hour seepage test', that is, fill the kitchen or bathroom with water. If it does not leak after 24 hours, it will be qualified. Is it safe to use overweight materials? In home decoration, it is sometimes necessary to use a large number of overweight materials to raise the floor, lay marble in a large area, build internal walls with bricks and make ceilings with complex structures, which may make the bearing capacity of the building exceed the design standard and lead to the building tilting and sinking. Therefore, light materials should be chosen as much as possible in home decoration. When raising the floor, you can choose lighter perlite blocks to avoid using reinforced concrete with solid structure; When laying granite and marble, the laying area should be controlled as much as possible; It is best to use light steel keel as the wall separating the rooms; When making a suspended ceiling, the structure should be simplified and light materials should be selected. Is it feasible to change the use of the house? Changing the kitchen into a bedroom is extremely dangerous, because once the gas leaks, the consequences will be unimaginable. Changing the outer balcony into a kitchen or bedroom is also not desirable, because the bearing capacity of the outer balcony floor is generally not large. After changing into a kitchen or bedroom, the stress on the balcony floor will increase, which is likely to cause the floor to break and fall off. It is not allowed to change a balcony without water into a kitchen. Eight, why should we choose a good time for family room decoration? The construction of family room decoration project is related to human factors, material efficiency and climatic conditions. The construction period of the decoration project should avoid major festivals. In case of major holidays in decoration, it is easy to delay the construction period. The weather is too hot or too cold, which is not good for operators. When the temperature is higher than 35℃, people sweat profusely during construction; When the temperature is lower than 5℃, the hands and feet are ineffective when working. Therefore, the renovation period should be selected during the temperature of 5℃ ~ 35℃. Some decoration materials will be affected by air temperature and humidity. For example, when the temperature is lower than 5℃, the coating will be sticky and thick, and it will not open and brush unevenly. If the wooden floor is laid under the condition of high humidity, when the humidity is small, the moisture in the board evaporates, and the board will crack and warp. To this end, all kinds of decoration materials must read the relevant instructions before construction to avoid construction under low temperature and high humidity climate conditions. Rainy and snowy weather brings inconvenience to the transportation of decoration materials. The road is muddy and the vehicles are difficult to travel; Some materials piled up in the open air need to be covered and more protective materials are needed; Some renovated parts (such as the ground, etc.) should be protected and covered with cardboard or straw curtains to prevent people from trampling on them, which also costs more protective materials. To this end, it is necessary to collect weather forecast information before decoration, and finally choose a day with little rain and no snow to avoid decoration in the cold winter and rainy season. The commencement and completion dates of decoration should be chosen in the owner's holiday. This is because the renovation starts and finishes the most, so the owners must participate, and the owners will have time to take care of this matter when they choose holidays. The best time to decorate a family room is autumn every year. Of course, it can be done in other periods except during the Spring Festival, depending on the local climate conditions. What time is not suitable for decoration? Newly completed buildings should not be decorated immediately. Generally, the traditional walls of buildings are between 24 cm and 5 cm, and the humidity of the walls is relatively high. It is more appropriate to decorate the walls after they are basically dry, so that it is not easy to cause wood deformation or mildew, which is beneficial to human health. It is not suitable for decoration in the season with high air humidity. There is a large amount of wood for home decoration, and wood and wood products have a considerable reaction to air humidity. We should try to avoid such a season. If the decoration is carried out in this season, we should pay attention to taking corresponding measures to prevent the wood and wood products from getting wet and increasing the water content, prevent the used metal products from rusting, lengthen the painting stage, and pay attention to the drying of the paint film. Where is the decoration in the peak season? After September every year, the home improvement industry entered the second peak season of the year. Due to the crisp autumn in September and October, coupled with the sharp increase in the occupancy of new buildings, the transaction volume of the whole home improvement industry during this period is several times higher than that in the previous three months. In the face of these prosperous decoration companies, some consumers can't help wondering: at this time, the general decoration companies take more orders, will there be a situation of' radish is not washed'? In fact, the decoration in the peak season also has some advantages: in autumn and winter, the traditional festival of China-Spring Festival is coming in a few months, and most of the construction workers, the main force of the home improvement industry, will go home for the Spring Festival, so they work faster at this time, hoping to settle their wages and go home for the Spring Festival as soon as possible, so compared with other seasons, it is rare for workers to dawdle and delay the construction period. But in this way, we must beware of some workers' radish will not wash the mud soon. For example, in order to grab a new project, there will be a sloppy ending to the last project. Therefore, remind consumers to strictly control the acceptance. Some decorative materials have started to be discounted and dumped. In recent years, the speed of upgrading decorative materials has become faster and faster, and most manufacturers like to set the launch time in spring, which will inevitably put some pressure on the sales of old products. For these manufacturers, it is a wise decision to sell their products at a discount during the decoration season, and consumers also have the opportunity to' find' good and cheap products, thus saving a sum of material costs.

Actually, it is easier to raise a bitch than a male dog. Usually, a bitch is more docile and less naughty than a male dog, but it is more troublesome when a bitch arrives at * * *. If she doesn't match, she will ovulate in a few days, which is almost the same as a girl's menstruation and other males and females. If she is raised, she should pay attention to vaccinating her, giving her 3 shots for the first time and one shot every year thereafter. Then, it is best not to give it a bath before the vaccine is finished, because the puppy's immunity is usually reduced and it is easy to get sick, and the vaccine is also a weak virus. Therefore, it is best not to take a bath during the vaccination. If it is really dirty, wipe it with a warm and wet towel. Of course, it is best to eat dog food, because it is better for the teeth and the BB is not so smelly. Eating other foods means paying attention to eating as little salt as possible and supplementing it with calcium. There are some foods that dogs can't eat, which are very harmful to dogs, such as chocolate, onions and seafood. Try not to give them. Take the dogs out for a walk and bask in the sun every day, and the puppies don't know how hungry they are, so don't feed them too much. The amount of feeding depends on the BB of the dog. If you feed them less, the BB will be dry and hard. If you feed them too much, it will be thin and soft, and the hardness will be moderate, which means that the feeding is just right. It's better to wait for the second time to pair the puppy. If you don't want the puppy to have children, you can also consider birth control. That's all.
