The nature, health and safety of the kitchen are of the utmost importance, and all major brands are committed to using newer, more environmentally friendly materials to achieve this. When people buy cabinets, it is easy to ignore many environmental problems related to the environment in the kitchen, such as: the noise brought by the drawers and cabinets in the kitchen, the cracking that will occur after a few years of use, energy consumption and so on. The environmentally friendly kitchen is not only environmentally friendly, but also should be reflected in the details of the core without noise, low energy consumption. Look at the following links to see if your kitchen is environmentally friendly.
First, the E1 cabinet
E0 grade plates do not contain green moisture-proofing agents. They do not need to be glued. The toughness and moisture resistance are relatively low. The substrate used for furniture will be very good, but it is easy to be wetted and broken in the kitchen. Cabinets that meet E1 environmental indicators can be called environmentally friendly cabinets.
Second, Conce
The inner cabinet body of the cabinet generally has a row of drill holes. If there is no cover, even if the plate meets the E1 standard, the formaldehyde in the cabinet will be slowly leaked. The small hole disappeared and the formaldehyde emission from the box was minimized.
Third, edge banding
The sealing process of the cabinet is very important. It is necessary to use the imported edge banding machine and also cooperate with the imported hot melt glue, so as to play the role of sealing the plate. Remind everyone that the correct side panel sealing method is to seal the four sides of the side panels, and the thickness is more than 1 mm.
Fourth, the back plate
Most manufacturers use single-sided stickers in the middle of the board or Polaroid board as the backboard material of the cabinet, which has a veneer on one side and a bare side on the other. The exposed surface does not prevent the release of formaldehyde. The backboard should be double-sided pasteboard, such as the dew river particleboard, which can reach the E1 standard.
Five, BLUM hinge and BLUM hinge damper
The noise reduction is also environmentally friendly. BLUM hinges and BLUM hinge dampers are installed on the cabinet to effectively prevent the noise generated when the door panel is closed and collide with the cabinet, and reduce the rebound speed of the door panel.
Sixth, anti-collision strip
The anti-collision strip and the edge strip are installed at one time in the production process, which not only slows down the impact of the door panel, eliminates noise, but also enhances the sealing property of the cabinet panel and prevents the panel from being deformed by moisture. Since there is no slotting, the edge strips are neat and tidy.
Seven, metal flexible architecture
In order to solve the problem of table cracking, it is possible to adopt a metal flexible structure suitable for artificial stone countertops, and replace the wooden structure with metal supports under the countertops to extend the use time of the countertops. The unique connection between the lower track and the lock card prevents deformation and cracking.
Eight, metal drawer
Plastic drawers are not environmentally friendly, and now the aluminum drawers are popular, and the main body is not plasticized. Such drawers not only use key parts for a long time, but also have a uniform color. The inner pumping is also made of aluminum alloy, which replaces the wooden baffle and is lighter and more durable.
PEI plastics (polyetherimide plastics) is an amber transparent solid. It has an inherent flame retardancy and low smoke concentration without adding any additives. The oxygen index is 47%, and the combustion level is ul94-v-0, and the density is 1.28~1.42 g/cm3.
PEI plastics has a strong thermal stability, and even the non-enhanced PEI plastics still has good toughness and strength.Therefore, the high thermal stability of PEI plasticsis used to make high temperature heat-resistant devices.
PEI plastics has excellent mechanical properties, electrical insulation performance, radiation resistance, high temperature resistance and abrasion resistance, and can be used by microwave.The PEI plastics also has good flame retardancy, chemical resistance and electrical insulation.Vitrification transformation temperature is very high, up to 215 ℃.PEI plastics also has a very low shrinkage rate and good mechanical properties.Adding fiberglass, carbon fiber or other fillings to enhance the purpose of modification;And other engineering plastics of heat-resistant polymer alloys, can be in 160 ~ 180 ℃ under the working temperature of use for a long time.
The long-term use of polyether amines in the us underwriters laboratory is 338T and 356T (according to the grade), and the combustion rating reaches UL94V - 0 (10 mille thickness).The oxygen index is 47, and the polyetherimide is in line with the requirements of the aircraft for the requirements of the FAA's flame retardant and thermal release material standards.It has a glass transition temperature of 419F and is allowed to be used intermittently under 392F, at higher temperatures, resulting in a short-term shift.Under 356T, the tensile temperature and flexural modulus were above 41 and 2068MPa respectively.The material reinforced with Glass Fiber and carbon fiber has higher strength and rigidity under the transition temperature of glass.
PEI plastics long-term resistance to creep under high temperature and stress allows it to replace metals and other materials in many structural devices.PEI plastics shows good performance in variable temperature, humidity and frequency.The low dissipation factor at GHz frequency makes the polyetherimide have high microwave wearability.Its ionic pollutant is low, at 250F100 % R.H.And 207kPa after 120 hours of water extraction with the conductivity, at 20 megaohm, it can be used as an electronic sensor element insulation.
PEI plastics is a fine coating and film forming material which can be used for the coating and film of electronic industry, and can be used in manufacturing aperture < 0.1 mu m, with high permeability microporous diaphragm.It can also be used as high temperature adhesive and high strength fiber.
Application field
Since PEI plastics has excellent comprehensive and balanced performance, PEI plastics has been applied to the departments of electronics, motor and aviation, and used as metal substitute materials for traditional products and cultural life supplies.Using PEI plastics instead of metal to make optical fiber connector, PEI plastics can optimize the structure of the component, simplify its manufacturing and assembly steps, and maintain a more precise size.Used in automobile industry, such as high temperature fittings for manufacturing, the high power lamp and light, control the car cabin outside temperature sensor (air conditioning temperature sensor) and the control of air and fuel mixture temperature sensor (effective combustion temperature sensor).Also can be used for high temperature erosion of lubricating oil vacuum pump impeller, distilling apparatus that operate at 180 ℃ of ground glass joints (following), the lighting of anti fog light reflector.
