The main character of the stairs in the modern family is the solid wood staircase, and the solid wood staircase occupies the main battlefield of high-end consumption. Then most people choose the wooden stairs, they only look at the style and price, and the other details about the quality of the stairs. One knows half or does not care. In fact, when purchasing wooden stairs, especially solid wood stairs, the moisture content of the wood and drying treatment should be paid more attention to the drying process to minimize the moisture content of the wood, and make the wood in the drying process. Avoid deformation cracking and increase the yield of wood. Many consumers have found that their own solid wood flooring has not been used for a year, and cracking has occurred. However, they usually pay attention to protection. How can this happen? In fact, not only solid wood flooring, some solid wood and solid wood. Such phenomena may occur in composite furniture, doors and windows, stairs, etc., and the most direct cause of this phenomenon is that the drying of the material is not in place. Under normal circumstances, the wood itself contains a certain amount of water, so some medium and large manufacturers will dry before making solid wood doors, solid wood stairs and other wood products, which is well known, but drying must follow certain The standard procedure, especially the attention to detail. There is also a professional drying equipment for drying, which is also a very large investment, so there are two kinds of wood drying treatment methods on the market. The first type: earth kiln drying. Some small manufacturers small workshops because of the lack of funds (and such drying is one-off), they will buy a piece of material when consumers order a door, order a staircase to buy a stair, other furniture is also the same Directly use the earth kiln built by yourself (that is, the burnt pit) to dry the wood, which reduces the cost, which can harm consumers and deceive consumers, because they will not say so when they sell. Because the earthen kiln uses the artificial burning temperature is not balanced, some of the materials in the burning process have been baked, and some of the water content is still high, (that is, the drying is not done) with such wood The life of the stairs and other wooden furniture is greatly reduced! And there is no chance to control the cracking of the wood. The second type: after steam drying, the second microwave drying is performed. 1, the first drying, using steam drying, the main principle is to add a certain syrup with steam from the outside to the inside drying, the cycle is generally 30-40 days. The main function is to kill and degrease with the syrup, then dry the water, destroy the original internal stress of the wood, and let the moisture content of the wood reach about 12%. Therefore, its drying is not thorough, because steam drying is carried out from the outside to the inside. Simply put, just like the sweet potato sweet potato we all know is this principle, often outside the paste, and the inside is still blunt. Therefore, whether drying is in place is also the key to determining the service life of wooden home improvement (especially solid wood stairs). (Some small manufacturers small workshops will be finished with this steam drying once) 2, then placed in the warehouse for 3-4 months, let it adapt to the temperature and humidity of the external environment. (This is very important for materials, but manufacturers without financial strength can't do it.) The production cycle has to be extended accordingly, so regular manufacturers generally have longer production cycles. 3. Then perform the second microwave drying before finishing (such as the microwave oven of the consumer's household is the principle of evaporation from the inside to the outside). The principle of this drying is to evaporate the water from the inside to the outside, so that the wood will not crack, deform and completely destroy the internal stress of the wood due to the sharp cold and heat, and the cycle is 24 hours. (Just because of the second drying, the cost per material increased by 2,000 yuan. The increased cost is about 15%. Because the cost of each drying kiln equipment is 1.65 million / Taiwan, the power configuration is 86KW, each time Drying to 1 square meter of wood, the cost per cubic increase = 86 * 24 = 2064 KW / hour * 1 yuan / degree = 2064 yuan, the unified wood industry group is equipped with 8 such equipment. Simply speaking, the German microwave balanced drying kiln is very expensive and costly. It is definitely not possible for small manufacturers and small workshops to use these equipments. Therefore, the production cycle of small manufacturers' small workshops is also very short! The price is relatively low. A unified wood industry snow children remind you that when choosing home furnishings wood products, we must choose a strong brand manufacturers, because the brand manufacturers have strong financial strength, strong brand awareness, strict and perfect management system, relatively speaking, let everyone choose More assured! And if a staircase is not doing well, it will affect the overall aesthetic effect of your decoration, but it will involve the personal safety of your family!
