Upholstered furniture mainly refers to furniture with sponge and fabric as the main body. Mainly include sofas, mattresses, -family:Song type”>soft bedandwithCompatible productsetc. Among them, mattresses and sofas are the two most important types of upholstered furniture. Software The material of furniture is soft and elastic, which can make people get a full rest, reduce fatigue at work, and obtain physical and mental pleasure. Therefore, it is also one of the most widely used and most frequently used furniture, and plays a pivotal role in the complex and huge furniture family. status.
Behind the comfort of upholstered furniture is the variety of internal multi-layer structures The role played by composite materials:
Taking mattresses as an example, if divided according to the main material, the mattress can Divided into spring mattresses, palm mattresses, sponge mattresses, and latex mattresses, among which spring mattresses are the most widely used. The structure of a spring mattress can be divided into fabric layer, filling layer, spring layer and edge. The fabric layers define the look and feel, the spring and padding layers provide stiffness and comfort, and the gussets provide edge support. Among them, the filling layer plays a vital role in adjusting the softness and comfort of the mattress.
The fabric layer is mainly made of various textiles, such as cotton, linen, silk , wool, chemical fiber, etc. The spring layer mainly has three types: Miaoerbuckle spring, Meizi spring and independent pocket spring. As the most important part, the material of the filling layer is more complex, including sponge, hemp, latex, fabric3DMaterials, pure natural animal and plant fibers, etc., the most important of which is sponge. Sponge generally refers to polyurethane sponge, because of its porous honeycomb structure, it has low density, good elastic recovery, sound absorption, breathability, heat preservation and other properties. And the hardness and resilience can be adjusted through formula and process to meet various product needs. The foreign body sensation of the sponge mattress is relatively low, and it has unique stress relief and shock absorption properties, and the time to fall asleep can be reduced compared with other mattresses60%, it is easier to maintain a deep sleep and provide consumers with quality sleep.
fromChemistryangle , the sponge can be divided into: ordinary sponge, slow rebound Sponge, high resilience sponge. TDIThe improvement of product quality can provide strong material support for the upgrading of sponge and upholstered furniture products, and is also a deep demand for the development of sponge and upholstered furniture industries.
In order to better meet the needs of downstream customers, Wanhua Chemical continues to optimize production Process flow, through the development of high-efficiency reaction technology, optimized adjustment and precise control of key parameters, minimize the generation of by-products and impurities from the source. At the same time, according to the impurities produced in the reaction, the impact of each component on downstream production and application is studied one by one, and self-developedTDIProduct refining technology effectively removes solvents, light and heavy components and trace impurities, greatly improvingTDIProduct quality, product purity improved and stabilized99.98%, hydrolyzed chlorine, acidity and other indicators have been greatly reduced, and the overall quality is much higher than the national product standard, reaching the industry-leading level.
4month3, Wanhua Chemical and Gujia Home Furnishing Joint Innovation Laboratory was established in Hangzhou.
