Bonded
NdFeB Magnet has the highest magnetic properties with free choice of
magnetization direction. Ring Magnet is capable of achieving radial and
multi-polar magnetization, and can be used to produce magnets of complex
shapes. Cladded with heat resistant plastics and additives, the
magnetic powder has excellent heat-resistant stability. Special resin
coating helps enable good corrosion resistance.
Generally, the Bonded NdFeB Magnet is produced by molding compression of the compound NdFeB alloy powder with epoxy resin, also it can be made by injection or extrusion from NdFeB alloy powder mixed with plastic. The characteristics are as follows: Bonded NdFeB Magnet,Ring Magnet,Motor Magnet Ningbo Hegao Magnetic Technology Co.,Ltd , http://www.allmagnetstores.com
In the past 10 years, the large-scale development of urban expansion, real estate development and residential decoration in China has promoted the progress of decoration and decoration projects in residential kitchens and bathrooms. The two series of “kitchen and health†have been changed in the past. The situation of ceramics, enamel and natural stone is replaced by the widespread use of artificial stone and FRP materials, and the development is very rapid.
According to the data provided by the China UPR Industry Association, in recent years, China's artificial stone resin has reached more than 350,000 tons, artificial stone production has reached 1.75 million tons, and nearly half of the kitchen and bathroom. According to the calculation of the “two rooms†of one household, the artificial stone and FRP materials are about 80 kg and 5 kg respectively.
The relevant person in charge of the association believes that artificial stone and FRP kitchen and toilet can quickly enter the country's thousands of households and halls in the past 10 years, because the freedom of artificial stone and glass fiber reinforced plastic materials is designed to achieve the perfect personality and art. Unification is an important reason to attract markets and customers. In addition, the molding process of artificial stone and FRP kitchen and bathroom is simple, diverse, fast and low-carbon. In the past five years, a number of stone companies in Guangdong, Fujian and Shandong have abandoned the way of resource-based stone mining, and vigorously introduced the production technology of artificial granite, marble and artificial sandstone to develop artificial stone of various uses. According to some data, in addition to artificial stone products in the “two roomsâ€, urban hotels, leisure centers, fast food restaurants, etc. also use artificial wall stone, artificial paving stone, artificial stone floor, sandstone sculpture, meteorite, Most of the glazed stone of translucent stone and high-end supermarket handicraft cabinets are made of transparent resin-based artificial stone.
It is reported that artificial stone is mainly divided into three categories in China: solid surface material, synthetic granite, and microcrystalline stone. In general, artificial stone mainly refers to the solid surface kitchen board. There are four or five imported brands and a large number of domestic brands in the domestic market. Imported brand manufacturers are large multinational companies, and the products are acrylic artificial stone. In the market, Samsung, DuPont and LG have the majority share of imported solid surface materials, but the market share is small, and most of them enter high-end residential decoration. In recent years, these foreign-invested companies have also turned to the manufacture of a wide range of polyester kitchen countertops. Imported solid surface kitchen countertops are generally designated by the manufacturer as an exclusive agent in a certain area. The agent designates a number of dealers or processors in their area. These distributors or processors are in the retail terminal such as the cabinet company showroom. , sales products, marketing strategies and sales prices are uniformly formulated by agents.
In contrast, domestic brands produce mostly polyester artificial stone. Domestic solid surface kitchen countertops are factory direct sales, large and small processors can buy plates from the factory, there will be many dealers and processors in a region, the price is also determined by themselves. Since the domestic solid surface material has not established a good sales system, the manufacturer has not established a network of powerful agents, distributors and processors, coupled with the low level of physical surface material processing, resulting in chaotic sales channels and prices. Disorderly competition, mutual price reduction.
The cabinet products are standardized products, and the cabinet makers provide the customers with standardized product solutions. After the cabinets are finished, the cabinets are determined according to the cabinets. Therefore, there are almost no on-site measurement and on-site production in foreign countries, all of which are standardized production. The same production sites, personnel, and production efficiency are more than ten times higher than domestic ones.
It is understood that the domestic solid surface kitchen board, the main production areas are concentrated in Guangdong, Zhejiang, Fujian and Jiangsu. The UPR used is basically o-benzene type, a small amount of benzene type and acryl type. After adding the accelerator, color paste, filler and colorant, the resin is thoroughly mixed and stirred, and then added with a curing agent before mixing, and then vacuum-cast. The template is 2440×760×12.7m/m aluminum frame splicing and 12m/m thick flat glass. After the casting is completed, it is exothermic and solidified, and enters the drying room to be matured. After the panel is cooled for several days, it is polished and packed.
According to the person in charge of the association, the artificial stone kitchen platen packing is medium-wearing aluminum hydroxide powder with different grades according to foreign standards. However, the filler used at present is very chaotic. A considerable number of enterprises cater to low-priced users and compete in the market. Calcium carbonate powder. The acid value of calcium carbonate powder is alkaline, hygroscopic and color-absorbing, and it is not resistant to dirt. This kitchen plate, commonly known as “calcium†board, is easily cracked under uneven heat or temperature difference, which has caused Customer complaints and returns. "In response, the China Kitchen and Bath Association has introduced the kitchen board industry standard this year, and it is expected to change this situation to a certain extent." Zhao Honghan said.
1.Higher Magnet Property: the magnet property of bonded NdFeB magnet is between that of sintered NdFeB and ferrite, and with good consistency and stability.
2.Large Freeness of Product Shapes and High Precision of Dimension: the magnet shape and dimension are decided by the tooling, like ring, segment, block, etc., without further sintering and mechanical machining processes.
3.Good Corrosion Resistance: after electrodeposited or through other special treatments, it can be used under normal or unfavorable environment conditions for a long time.
4.Diverse magnetization: Multi-pole magnetization and screw angle magnetization are available, and the field distribution could be square, sinusoid and so on.
5.It has high production efficiency, suitable for mass production.The bonded NdFeB magnet is mainly used for all kinds of micro–miniature motors, such as spindle motor, stepping motor, synchronous motor, DC motor and brushless DC motor. It can replace Sintered Ndfeb Magnet and ferrite, making motor assembling simpler and more reliable, reducing costs and improving efficiency.
The cabinet market drives the development of the artificial stone market behind the hidden crisis
The cabinet industry has experienced more and more development in the past 20 years, and it has also promoted the development of artificial stone countertops. With the popularization of cabinet products, the production, processing and sales of artificial stone have sprung up. However, behind this kind of prosperity, the crisis is deeply hidden, especially the problems of unevenness and disorderly competition in the artificial stone processing industry, which seriously restricts the development of the entire cabinet industry.
