Wooden doors how much temperature will be deformed
85 ~ 95. Wooden door is the use of ultra-fine wood powder and polymer resin mixture, made by the molding process, both wood and plastic excellent characteristics, the production of products to achieve the effect of real imitation wood. As the use of raw materials and production processes do not use glue bonding, will not produce formaldehyde, benzene, ammonia, trichlorethylene and other harmful substances, is a substitute for traditional wood green new materials. The main raw material of wood-plastic doors is PVC resin and high-quality wood powder, PVC resin using domestic medical grade brand-name products, wood powder by the professional wood company to provide high-quality wood powder, after grading screening, grinding, drying, Finished product on the quality requirements of raw materials. Wood-plastic door system with a certain proportion of auxiliary materials, adding stabilizers, foaming agents, modifiers, etc., a variety of ingredients according to strict mixing ratio, effectively guarantee the quality of foam sheet products. Wood-plastic door production equipment has a mixing system, extrusion system, a high degree of automation, which mixing equipment with the amount of ingredients accurate, mixed evenly, high efficiency, fundamentally to ensure the stability of the product. As the production of wood-plastic foam door production of foam extrusion equipment requirements are higher, the use of high-torque twin-screw extruder, and screw, screw and other components to transform to meet the lignin inside and outside the surface crust and uniform hair Soak, to avoid charcoal charcoal and other phenomena occur. Wood-plastic doors using thermal transfer process, in the extrusion of the plate on the transfer of various graphics, the product has a variety of high-grade tree grain and color, according to the market popular varieties to design to meet the needs of modern consumer life personality.

What is the warm lead of the heating cable
You can understand the next million warm smart electric heating system technology mature product quality guaranteed heating cable ten years warranty thermostat two years warranty period comfortable, healthy, energy saving, environmental protection, the best choice for home heating.
What is the composition of the heating system?
Heating systems, heating systems, boiler systems, outdoor pipe networks, indoor pipe networks and radiators. The energy consumed by the traditional heating and heating system is fuel, and the energy consumed by the electric heating and heating system is electricity. Therefore, in the environmental protection requirements of high urban heating and heating, coal-fired boiler room or coal-fired stove will be strictly limited to use, replaced by several possible forms of heating are mainly concentrated heating of the saucer segment Boilers, large electric heat pump and gas boiler room and scattered in the user's room within the home gas stove, electric heater and so on. At the same time, in order to reduce the power grid power generation peak and valley difference, but also consider the heating system set up in the heat storage device, so that meet the heating requirements at the same time, the load on the power load play a role.
What is the difference between the hydraulic module and the original hydraulic module? Please master as much as possible to say the details?
The heat exchange between two kinds of media is one end of the hot and cold source. Hot and cold sources, can be industrial steam, hot water, waste off the urge to criticize the waste of too much water, waste heat and other hot media, can also make ice water, freon and other refrigerant. Can be provided by the heat supply plant, garbage burning plant, boiler, heat pump host. After the heat exchanger through the transfer, will be directly or indirectly cold and hot energy transfer use. Use the end, can be a variety of common terminal load equipment, to warm coil, heat sink, capillary air conditioning, water tanks and so on. As for the landlord mentioned the hydraulic module, the use of plate for specific aspects of which, or to find manufacturers
What is the difference between the quality of the new generation of red tube and the original?
The role of the day heat pipe: the pipe has a good oxygen barrier performance can effectively delay the corrosion of metal parts in the system to extend the life of metal parts and reduce the fouling of the pipeline system. Red and more warm, and white in the phase of the convulsions of the chewing sticks, and more difficult to heat the case, if the outside of the white is better
Home to install 400 atmospheric boiler on the first floor, to the second floor for the warm, the water tank in the boiler next to the circulation pump is 500 watts head 8 meters, equipped with a check valve, Equipment into the export are installed automatic valve, but the temperature of a 40 degrees there is gas parked in the pump, the hot water on the up, please enlighten me master
