Shandong which microwave equipment package to teach insulation board drying technology, chain transmission of high temperature resistant and reliable operation, automated temperature control output speed, to achieve the output are qualified products. New perlite drying equipment, a fire brought about by a new revolution in thermal insulation materials, a fire in Shanghai makes the urban disease is now especially obvious lag, wall safety by the fire challenge, a new type of flame retardant materials thus born, that is, heat preservation and insulation perlite wall panels, the material is light, easy to process, powerful, environmentally friendly and so many other advantages, so that the perlite enterprises now like asparagus piece of land blossomed. Now well, our company's production of microwave equipment and add new uses for heat insulation materials for rapid drying, equipment covers an area of small, Sui open with the use of energy-saving features such as no preheating by Yancheng, Shenyang, Tianjin Yingkou, Jining perlite manufacturers of the favor.
Jinan Longtuo brand microwave perlite drying machinery | 200kw perlite plate production line | perlite microwave dryer price | drying equipment on the market so much, why also recommend microwave drying perlite plate equipment, the reason why the choice of the equipment on the list of reasons, microwave has the following points. Industrial microwave equipment for most customers are the first time to use, due to the use and operation methods do not understand, often worry about the service life of microwave equipment. In fact, a reasonably designed and successfully utilized microwave equipment service life is very long, its mechanical part due to the slow speed, the load is not high, generally very few failures. Microwave cavity part if the material is sufficient, there is almost no chance of problems. The rest is the electrical part. The Panasonic magnetron (microwave generator) in the electrical part is an electric vacuum device with a certain service life. Under normal use, the service life is generally 8000-10000 hours, if the control part of the design in place, the service life can be more than 12000 hours is also very normal. Subsequently, it will slowly weaken. In addition, the circuit components in the high-voltage capacitors, high-voltage silicon pile of the service life and the specific operating environment, they all belong to the perishable components, the replacement cost is also very cheap, will not have a significant impact on the cost of use. Therefore, please purchase the manufacturer with the strength of research and development is the only guarantee.
1. Microwave has selective heating. Because the water molecules on the microwave energy absorption is the best, so the part of the water content is high, the absorption of microwave power is more than the part of the water content is lower. This is the characteristics of selective heating, the use of this feature can be uniform heating and uniform drying;
2. Microwave drying and dehydration of water and gas direction from inside to outside. Therefore, microwave drying has a puffing effect on the original because of water vapor caused by small bubbles with the role of evacuation, so you can maintain the original hollow state.
3. Environmental protection, energy saving and high efficiency. Microwave is directly on the role of the material, so there is no additional heat loss, the air inside the furnace and the corresponding container will not heat, so the thermal efficiency is very high, the production environment will be significantly improved, and far-infrared heating compared to the power savings of 30%.
4. Simple button operation is easy to control, advanced process. Compared with conventional methods, the equipment that is open and ready to use; no thermal inertia, flexible and convenient operation; microwave can be based on the thickness of the material to adjust the drying time, microwave size and power adjustable. In microwave heating, drying, no waste water, no exhaust gas, is a safe and harmless technology. The following talk about the requirements of drying perlite board
Perlite is a lightweight, multi-functional new material with light apparent density, low thermal conductivity, good chemical stability, wide range of use temperature, moisture absorption capacity is small, and non-toxic, odorless, fireproofing, sound-absorbing and other characteristics, widely used in a variety of industrial sectors. Perlite fireproof board, is a new type of fireproof door core filling material made of expanded perlite, pre-built skeleton, with applicable adhesive as binder, after pressure. In the past few years, the microwave industry has begun to figure out how to quickly dry and digest the insulation board of the large logistics field quickly, the beginning of the volume are not very large, so the equipment to buy a small, and now the sales go up, the site has, so also the original small equipment to refit into a large microwave baking line, so we are also working on the original to buy a small piece of equipment for the enterprise to modify the high-power microwave production line.
Perlite board microwave dryer features:
1, fast drying speed, high efficiency, good product color. According to information, microwave drying speed than the commonly used convection drying speed 20 to 30 times faster.?
2, drying uniformity, no deformation, no cracking. Due to the microwave effect of the internal and external parts of the material at the same time, the heat is uniform, so the microwave treatment of materials, drying uniformly and thoroughly, improve product quality, the surface will not plate knot, improve the toughness, to ensure that there will be no cracking, deformation, discoloration, can be corrected curvature and so on.
3, energy efficient. Drying materials with far-infrared and steam energy, its energy utilization rate of less than 50%, while the utilization rate of microwave as an energy source can reach more than 75%, more than 25% lower than the far-infrared and steam drying energy consumption, perlite insulation board using microwave drying 125px or so of the plate only 5-10 minutes to complete the dehydration curing.Microwave heating principle microwave is the frequency from 300MHz to 300GMHz electromagnetic waves, its direction and size at any time for periodic changes. Microwave and material direct action, the ultra-high frequency electromagnetic waves into thermal energy process that is the microwave heating process. Water is a strong absorption of microwave materials, materials in the water molecules are polar molecules, under the action of microwave, its polar orientation with the change of the external electromagnetic field changes, resulting in molecular friction, collision, so that the material to produce a series of processes such as thermalization and expansion to achieve the purpose of microwave heating. Welcome to engage in high-tech clean energy building materials industry need to dry dehydration of enterprises to visit! More contribution to the construction of environmental protection, for the blue sky is no longer a memory.
